Description

Technical Field

[0001] The present application relates to the field of decoration and repair, and more specifically to a system and method for curing mold and alkali efflorescence on walls and preventing water seepage on walls. Background Art

[0002] Mold and alkali reversion is a common hazard in construction. It's primarily caused by the physical and chemical reactions of soluble acidic and alkaline substances within building materials as they absorb water and migrate and evaporate as temperature and humidity fluctuate. This reaction damages the building materials accordingly. Mold and alkali reversion is most common in kitchens, bathrooms, showers, exterior building walls, and the corresponding interior walls. This is because these walls are more susceptible to moisture, and moisture can "micro-siphon" through tiny cracks and crevices in building materials. During this "micro-siphoning" process, moisture converts between liquid and gaseous states, further increasing its ability to penetrate building materials and ultimately leading to mold and alkali reversion.

[0003] The hazards of mold and alkali return include: 1. It causes the wall to turn yellow or black, affecting the aesthetics of the wall; 2. It causes human skin allergies, stimulating the skin to develop rashes and itching or redness and swelling; 3. When the human body inhales a large amount of moldy gas, it will stimulate the nervous system and cause symptoms of dizziness and fatigue; 4. Mold metabolites can cause symptoms such as headaches, dizziness, nausea, nasal congestion and red eyes. In severe cases, bacteria may even enter the body and cause myocardial cell ischemia and necrosis, heart failure and other conditions.

[0004] The existing method mainly involves scraping and repainting the moldy and alkali-returning areas. After each scraping and repainting, the corresponding wall surface will no longer be moldy and alkali-returning for a period of time. However, this method only treats the symptoms and not the root cause, and rework is required after a certain period of time. Summary of the Invention

[0005] In response to the shortcomings of the existing technology, the present application provides a system and method for curing mold and alkali efflux on walls and preventing water seepage on walls. The system standardizes the treatment steps and reduces the difficulty of treatment, so that ordinary users can also complete the wall treatment by themselves. At the same time, the system can also fill the cracks and gaps in the building materials after treatment, effectively avoiding the occurrence of "micro-siphoning phenomenon", thereby preventing water seepage on the wall and fundamentally curing the mold and alkali efflux phenomenon.

[0006] A system for curing mold and alkali efflorescence on walls and preventing water seepage on walls, comprising a standard atlas, a process flow chart, a scraper, a high-speed micro-blower, a stirrer, a penetrating sand-fixing agent, powder, liquid, sealed twisted fiberglass cloth, a scraper, a brush, quartz sand and a sandblasting machine, which are used in conjunction with each other.

[0007] A method for curing moldy and alkali-rich walls and preventing water seepage on walls, comprising the following steps:

[0008] (1) Determine the construction area based on the mold and alkali condition of the wall;

[0009] (2) Remove the wall surface in the construction area to obtain the construction leveling layer;

[0010] (3) Blow away the dust and water vapor attached to the wall after the construction leveling layer is scraped off;

[0011] (4) Spray a permeable sand-fixing agent on the construction leveling layer to form a sand-fixing sealing layer;

[0012] (5) Preparation of functional slurry;

[0013] (6) Apply the functional slurry on the sand-fixing sealing layer to form the first slurry layer;

[0014] (7) Lay the sealing fiberglass cloth on the first slurry layer;

[0015] (8) Apply the second layer of slurry on the sealed fiberglass cloth;

[0016] (9) Apply the third slurry layer on the second slurry layer.

[0017] The permeable sand-fixing agent described in step (4) is prepared by mixing methyl methacrylate and a diluent in a weight ratio of 3:7 to 4:6; the diluent is dichloromethane.

[0018] The functional slurry in step (5) is prepared by mixing a powder material and a liquid material, wherein the weight ratio of the powder material to the liquid material is 1.5:1 or 2:1;

[0019] The components of the liquid material and their weight parts are: 85 parts of acrylic emulsion, 0.15 parts of hydroxyethyl cellulose 250HBR, 14.3 parts of deionized water, 0.35 parts of NXZ defoamer, 0.1 parts of GT-50 preservative, and 0.1 parts of AMP-95;

[0020] The components of the powder and their weight parts are: 50 parts of Portland cement, 20 parts of glass flakes, 15 parts of quartz sand, 3 parts of silicon dioxide, and 12 parts of mineral fiber.

[0021] The particle size of the silicate cement is 0.2 mm, the particle size of the glass flakes is 0.005 mm, the particle size of the quartz sand is 0.5 mm, and the particle size of the silicon dioxide is 0.0003 mm.

[0022] The twist-sealed glass fiber cloth in step (7) is obtained by impregnating the glass fiber cloth with a diluted acrylate emulsion and drying it; the dried acrylate emulsion on the twist-sealed glass fiber cloth adheres to the periphery of all mesh holes on the twist-sealed glass fiber cloth, and the centers of all mesh holes on the glass fiber cloth are through holes; the diluted acrylate emulsion is prepared by mixing acrylate emulsion and water in a weight ratio of 3:7.

[0023] The second slurry layer in step (8) needs to completely cover all the through holes on the fiberglass cloth.

[0024] The scraping coating described in step (8) and step (9) refers to applying the functional slurry on the sand-fixing sealing layer using a scraper so that the functional slurry and the sand-fixing sealing layer are more tightly combined; the brushing described in step (6) refers to applying the functional slurry on the sealing fiberglass cloth or the second slurry layer using a brush.

[0025] In step (6), if there are weak parts of the building in the construction area, it is necessary to first apply the functional slurry 2-3 times on the sand-fixing sealing layer of the weak parts of the building, and then proceed to step (6) after the functional slurry is dry.

[0026] If a finishing material needs to be pasted after step (9), quartz sand needs to be sprayed on the surface of the third slurry layer before vitrification occurs; the mesh size of the sprayed quartz sand is 80 mesh, and the quartz sand is sprayed by a sandblasting machine; if a finishing material does not need to be pasted after step (9), putty and latex paint can be applied in sequence after the third slurry layer is dried.

[0027] Compared with the prior art, the embodiments of the present application have the following beneficial effects:

[0028] The present invention is easy to operate and has standardized and orderly usage steps, so that ordinary users can complete the wall treatment by themselves. At the same time, cracks and gaps in building materials can be filled after treatment, effectively avoiding the occurrence of "micro-siphon phenomenon", thereby avoiding water seepage on the wall and fundamentally controlling the mold and alkali backflow phenomenon.

[0042] Example 1

[0043] A system for curing mold and alkali efflorescence on walls and preventing water seepage on walls, comprising a standard atlas, a process flow chart, a scraper, a high-speed micro-blower, a stirrer, a penetrating sand-fixing agent, powder, liquid, sealed twisted fiberglass cloth, a scraper, a brush, quartz sand and a sandblasting machine, which are used in conjunction with each other.

[0044] Standard atlas such as Figure 2 、 3 As shown, it will display standard construction drawings for decoration and repair, so that users can construct according to the drawings. The standard drawing set is the existing technology in this field. Those skilled in the art can complete its setting and use without creative work, so it will not be described in detail here.

[0045] Process flow chart as follows Figure 4 As shown, its role is to let users complete the operation through the correct process flow, thereby better standardizing the processing process and ensuring the quality of the processed products.

[0046] Example 2

[0047] A method for curing moldy and alkali-rich walls and preventing water seepage on walls, comprising the following steps:

[0048] (1) Determine the construction area based on the mold and alkali condition of the wall;

[0049] When determining the construction area, in addition to the wall where mold and alkali have occurred, you also need to extend 2-5CM to the outside of this range as the construction area.

[0050] (2) Remove the wall surface in the construction area to obtain the construction leveling layer;

[0051] The wall can be scraped with a spatula, or you can choose the tool yourself according to the actual area of the construction area. For the subsequent construction effect, the wall should be scraped as clean as possible; the construction leveling layer is the leveling layer of the original wall.

[0052] (3) Blow away the dust and water vapor attached to the wall after the construction leveling layer is scraped off;

[0053] This step generally involves first using a larger blowing tool to blow away the overall dust in the construction area, then using a brush to brush off the dust that is more firmly adhered to the construction area, and finally using a blowing tool such as a blower that can blow hot air to remove the remaining dust and overall water vapor.

[0054] (4) Spray a permeable sand-fixing agent on the construction leveling layer to form a sand-fixing sealing layer;

[0055] The permeable sand-fixing agent is prepared by mixing methyl methacrylate and a diluent in a weight ratio of 3:7 to 4:6; the diluent is dichloromethane.

[0056] After spraying, the permeable sand fixation agent will penetrate into the cracks or gaps of building materials, and its penetration depth can reach 3-7mm. After the diluent evaporates, the methyl methacrylate will undergo polymerization and solidify into polymethyl methacrylate, which will complete the filling of the cracks and gaps in the building materials, effectively completing the blocking of channels through which water can penetrate.

[0057] (5) Preparation of functional slurry;

[0058] The functional slurry is formed by mixing powder and liquid, and the weight ratio of powder to liquid is 1.5:1 or 2:1. In order to avoid uneven stirring caused by manual stirring, the powder and liquid are poured into a container and stirred evenly by a stirrer, which better ensures the use effect of the functional slurry.

[0059] Among them, the weight ratio of powder and liquid in the functional slurry scraped on the sand-fixing sealing layer at the weak parts of the building is 2:1, and the weight ratio of powder and liquid in the functional slurry used in the first slurry layer, the second slurry layer and the third slurry layer is 1.5:1.

[0060] The components of the liquid material and their weight parts are: 85 parts of acrylic emulsion, 0.15 parts of hydroxyethyl cellulose 250HBR, 14.3 parts of deionized water, 0.35 parts of NXZ defoamer, 0.1 parts of GT-50 preservative, and 0.1 parts of AMP-95;

[0061] The components of the powder and their weight parts are: 50 parts of Portland cement, 20 parts of glass flakes, 15 parts of quartz sand, 3 parts of silicon dioxide, and 12 parts of mineral fiber.

[0062] The particle size of the silicate cement is 0.2 mm, the particle size of the glass flakes is 0.005 mm, the particle size of the quartz sand is 0.5 mm, and the particle size of the silicon dioxide is 0.0003 mm.

[0063] Portland cement is used as a gelling inorganic powder;

[0064] The glass flakes have a palace-style multi-layered structure, which makes them structurally impermeable and corrosion-resistant, and can be more effectively anti-corrosion, waterproof and anti-seepage;

[0065] The function of quartz sand is to resist pressure and wear;

[0066] The role of silica is to increase density and impermeability;

[0067] The role of mineral fiber is to improve crack resistance and density. In this application, the mineral fiber is selected from ceramic fiber, which has a needle-like structure, which can make the integrity of the coating better and make the adhesion between the inorganic powders tighter, thereby improving the "hydrophobicity" and "water pressure penetration resistance" of the coating.

[0068] The powder of the present application is graded by mixing inorganic powders of different particle sizes, especially the addition of glass flakes, so that after the construction of the waterproof coating, the glass flakes can be arranged in parallel and overlapping in the coating, thereby forming a flat palace-like structure with an aspect ratio of up to 30-120. The penetration of water in the cured coating must pass through countless tortuous paths, so the penetration distance in a certain thickness of the anti-seepage coating is greatly extended.

[0069] (6) Apply the functional slurry on the sand-fixing sealing layer to form the first slurry layer;

[0070] Brushing refers to using a brush to apply the functional slurry on the sand-fixing sealing layer so that the functional slurry and the sand-fixing sealing layer are more tightly combined.

[0071] If there are weak parts of the building in the construction area, it is necessary to first apply functional slurry 2-3 times on the sand-fixing sealing layer of the weak parts of the building, and then proceed to step (6) after the functional slurry is dry.

[0072] The weak points of a building mainly refer to the locations on the wall where holes or grooves are punched or where pipes, wires, etc. directly pass through.

[0073] (7) Lay the sealing fiberglass cloth on the first slurry layer;

[0074] The sealed twisted glass fiber cloth is obtained by impregnating the glass fiber cloth with diluted acrylate emulsion and drying it; the dried acrylate emulsion on the sealed twisted glass fiber cloth adheres to the periphery of all mesh holes on the sealed twisted glass fiber cloth, and the centers of all mesh holes on the glass fiber cloth are through holes; the diluted acrylate emulsion is prepared by mixing acrylate emulsion and water in a weight ratio of 3:7.

[0075] Since both the sealing fiberglass cloth and the functional slurry contain acrylic esters, the sealing fiberglass cloth and the second slurry layer can be more effectively integrated. The sealing fiberglass cloth integrated with the second slurry layer acts as a bracket, effectively improving the integrity of the wall coating.

[0076] By setting up sealed twisted fiberglass cloth, the various materials in the construction area can be more integrated after drying, making them more firmly fixed to the wall, and effectively avoiding the situation where some materials fall off the wall.

[0077] Compared with the sealed twisted glass fiber cloth used in this application, the defects of the non-woven fabric used in the prior art are that it is not resistant to corrosion and has weak support. The defects of the ordinary glass fiber cloth used in the prior art are that it has poor fusion with the coating covering the glass fiber cloth, and cavities are easily formed, which affects the overall coating effect.

[0078] (8) Apply the second layer of slurry on the sealed fiberglass cloth;

[0079] The second slurry layer needs to completely cover all the through holes on the fiberglass cloth.

[0080] (9) Apply the third slurry layer on the second slurry layer.

[0081] The scraping coating refers to applying the functional slurry on the sealed twisted fiberglass cloth or the second slurry layer using a scraper.

[0082] If no finishing material is required after step (9), then putty and latex paint can be applied in sequence after the third slurry layer is dry.

[0083] Because permeable sand-fixing agents penetrate building materials and effectively block water seepage paths or channels, when water seepage on exterior walls causes mold and alkali backflow indoors, this can also be prevented by treating the walls indoors. Therefore, when water seepage occurs on the walls of high-rise buildings, waterproofing can be achieved by treating only the interior walls in this way. This eliminates the need to hire high-altitude workers like Spider-Man to perform high-altitude work on the exterior walls, reducing treatment costs while effectively avoiding the various risks associated with high-altitude work.

[0084] Example 3

[0085] The only difference between this embodiment and embodiment 2 is that, if a finishing material needs to be pasted after step (9), quartz sand needs to be sprayed on the surface of the third slurry layer before vitrification occurs.

[0086] The mesh number of the sprayed quartz sand is 80 mesh, and the quartz sand is sprayed by a sandblasting machine.

[0087] Spraying quartz sand can better improve the fulcrum between the finishing material and the wall, and improve the firmness of the finishing material adhesion.

[0088] like Figure 1 As shown, a sandblasting machine includes a handheld structure, a micro blower 4 arranged on the handheld structure, and a silo 11 arranged on the handheld structure.

[0089] The silo can be made of a bottle with a threaded opening, which can be inverted and fixed to the handheld structure through the threaded opening so that the quartz sand in the threaded opening can fall downward under the action of gravity. The mesh size of the quartz sand should be greater than 80 mesh to ensure that the micro fan can blow it out normally.

[0090] The handheld structure consists of a front power storage handle 9, a mixing chamber 6 arranged on the front power storage handle 9, an air duct 5 passing through the mixing chamber 6 from front to back, and a rear handle 2 connected to the air duct 5.

[0091] The front power storage handle contains a rechargeable power source, which has two functions: one is to provide a gripping mechanism for people to operate, making the device easier to hold; the other is to power the micro blower so that the product can be used when there is no external power supply, thereby improving the flexibility of the product.

[0092] The air duct 5 is connected to the mixing chamber 6; a charging port 8 connected to the front power storage handle 9 is provided on the side wall of the mixing chamber 6.

[0093] The charging power supply can be charged through the charging port. This technology is existing technology. Those skilled in the art can complete its setting and use without creative work, so it will not be described in detail here.

[0094] The front end of the air duct 5 is also provided with a nozzle 10 that matches the air duct 5.

[0095] The function of the nozzle is to adjust the coverage area and coverage rate per unit area of the sprayed quartz sand through different openings, so as to meet the different static friction forces required by different finishing materials.

[0096] The front end side surface of the rear handle 2 is fixed to the side surface of the air duct 5, and the rear handle 2 is in an "L" shape.

[0097] The rear handle is designed in an L shape, which is more convenient for users to hold and control.

[0098] The rear handle 2 is provided with a switch 3 which is electrically connected to the front power storage handle 9 and is used to control the micro fan 4 .

[0099] The switch allows users to more easily control the opening and closing of the micro fan, further improving the convenience of product use.

[0100] The air outlet of the micro fan 4 is connected to the end of the air duct 5.

[0101] The silo 11 is inverted above the mixing silo 6 , and the silo 11 is communicated with the mixing silo 6 ; the mixing silo 6 is provided with a sand inlet 7 communicated with the mixing silo 6 .

[0102] An adjustable feed valve can also be set at the sand inlet to further increase the amount of sand blasting by controlling the opening and closing degree of the feed valve, thereby improving the controllability of the product.

[0103] It should be noted that the silo is only provided with one opening for discharging materials, the purpose of which is to prevent wind from leaking out of the silo, thereby ensuring the effect of product discharging.

[0104] A support base 1 is further provided at the lower end of the rear handle 2 , and the bottom surface height of the support base 1 is the same as the bottom surface height of the front power storage handle 9 .

[0105] The purpose of setting the support base is to facilitate the product to be placed directly on the ground.

[0106] It should be noted that all features disclosed in this specification, or steps in all methods or processes disclosed, except for mutually exclusive features and / or steps, can be combined in any manner.

[0107] Furthermore, the above-described specific embodiments are merely illustrative. Persons skilled in the art may devise various solutions based on the disclosure of the present invention, and such solutions fall within the scope of the present invention and are intended to be protected by the present invention. Persons skilled in the art should understand that the present description and drawings are intended to be illustrative and not to limit the scope of the claims.
