[0030] The following will be combined with the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0031] See also Figure 1 The present invention provides an environmentally friendly glass fiber filter material, and a manufacturing process of the environmentally friendly glass fiber filter material, comprising the following manufacturing steps:

[0032] Step 1: Raw material processing

[0033] The staff puts the prepared raw materials in a mixer according to the proportion for mixing, and adds various auxiliary materials to accelerate the mixing during the mixing process. After the mixing is fully completed, the mixed material is obtained for use;

[0034] Step 2: Melting and drawing

[0035] The mixed material obtained by the treatment in step 1 is sent into a high-temperature furnace, and the mixed material is melted into a glass liquid by the high-temperature furnace. After the mixed material is melted into a glass liquid, the glass liquid material is drawn into glass fiber yarn by a wire drawing machine to obtain glass fiber for standby use;

[0036] Step 3: Textile Sizing

[0037] The glass fiber produced by the step 2 is subjected to textile processing by a wire arrangement machine and a twisting machine, so that the glass fiber is made into glass fiber gauze or glass fiber fabric, and then the glass fiber gauze or glass fiber fabric is sizing treated with a sizing agent, thereby completing the textile sizing treatment of the glass fiber;

[0038] Step 4: Hardening

[0039] The glass fiber after the textile sizing treatment in step three is preheated, and after the preheating of the glass fiber is completed, a hardener is coated on the surface of the glass fiber, and then the glass fiber after the coating of the hardener is heated again, and after the reheating is completed, the glass fiber product is taken out of the heating equipment and allowed to cool naturally to room temperature, thereby completing the manufacturing process of the environmentally friendly glass fiber filter material.

[0040] In step 2, the glass fiber includes the following raw material compositions by weight: 10-20 parts of E-glass fiber, 10-20 parts of C-glass fiber, 10-20 parts of A-glass fiber, 10-20 parts of E-CR glass fiber, 11-18 parts of D-glass fiber, 10-19 parts of S-glass fiber and 12-18 parts of AR-glass fiber, 5-7 parts of sizing agent, 3-5 parts of modifier, and 2-3 parts of additive. Among them, silicone sealant is commonly used in building curtain walls, doors and windows, and outdoor sun rooms due to its excellent weather resistance, high and low temperature resistance, UV resistance, and aging resistance. Polyurethane adhesive has good bonding strength, water resistance, chemical resistance, and weather resistance, and is suitable for Used for bonding and sealing of various outdoor building structures, acrylic adhesives are suitable for bonding various outdoor materials such as metal, ceramics, and wood with their strong bonding force, large initial adhesion and good weather resistance. Modified polymer sealants have good weather resistance, flexibility and adhesion, and are suitable for sealing joints on building exterior walls. In addition to silicone sealants, other silicone-based sealants are also widely used due to their weather resistance, temperature resistance and chemical resistance. Epoxy resin adhesives have good bonding strength and chemical resistance, and some modified epoxy resins also have good outdoor weather resistance. Modified silane sealants combine the weather resistance of silane and the flexibility of polyurethane, and are suitable for sealing outdoor joints and cracks.

[0041] The modifier is a silane coupling agent, the modifier is sodium sulfonate of lignin, the additive is tetratitanic acid, and the sizing agent is waterborne polyurethane.

[0042] In the process of mixing, in order to ensure the uniformity and stability of the mixture, it is usually necessary to add appropriate amounts of various auxiliary materials. These auxiliary materials may include adhesives, thickeners or other modifiers, which can increase the viscosity and fluidity of the mixture and promote the full mixing and reaction of the raw materials.

[0043] The entire raw material processing process requires strict operation control and process flow management to ensure that the quality and proportion of the mixed materials meet the requirements. Only through carefully designed and finely regulated raw material processing can we provide a high-quality raw material basis for subsequent production processes, thereby ensuring that the performance and quality of the final product meet the standards and requirements.

[0044] In step 2, when the mixed material is subjected to high-temperature melting treatment in a high-temperature furnace, the temperature of the high-temperature furnace is 1200-1600 degrees Celsius, and the high-temperature melting treatment time is 30 minutes to 60 minutes.

[0045] In step 2, melting and drawing is a crucial part of glass fiber manufacturing. First, the mixed material after step 1 is transported to a high-temperature furnace. The furnace plays a vital role here. Its temperature is controlled between 1200-1600 degrees Celsius to ensure that the raw materials reach a sufficient melting temperature. This high temperature condition is necessary because only at high temperatures can the various raw materials be fully fused to form a uniform glass liquid.

[0046] The high-temperature melting process in the furnace usually takes 30-60 minutes, which allows the raw materials to fully melt and reach the required viscosity and fluidity. In this process, the temperature control in the furnace is very critical, because too high or too low temperature may affect the quality and stability of the glass liquid.

[0047] Once the raw materials have reached the appropriate molten state, they can be transported to the wire drawing machine for wire drawing. The wire drawing machine realizes the transition from liquid to solid by drawing the glass liquid material into fiber filaments. This process requires high precision control to ensure that the diameter and quality of the wire meet the requirements.

[0048] Finally, through this step, the glass fiber filaments are prepared and can be used for subsequent processing and production. This process requires not only precise control under high temperature conditions, but also highly professional operation and management of equipment and raw materials to ensure maximum product quality and production efficiency.

[0049] In step 2, when the wire drawing machine is drawing the glass liquid material, the processing temperature is 1100-1200 degrees Celsius, the wire drawing speed of the wire drawing machine is 10-12m / min, and the drawn fiber length is 2400m-3600m.

[0050] In the second step of preparing glass fiber, melting and drawing is a key process. Once the mixed material processed in step one is sent into a high-temperature furnace, the high temperature environment causes the raw materials to quickly reach a melting state and form a glass liquid with high fluidity. This process requires strict control of the furnace temperature to ensure that it remains stable within the range of 1200-1600 degrees Celsius to ensure that the raw materials are fully melted without overheating or cooling.

[0051] Once the raw materials have reached a suitable melting state, the next step is the work of the wire drawing machine. The wire drawing machine plays a vital role in this step. It can draw the liquid glass material into thin and long glass fiber filaments. In this process, the working temperature of the wire drawing machine is usually controlled between 1100-1200 degrees Celsius, which can not only ensure the fluidity of the glass material, but also prevent the material from overheating and causing quality degradation.

[0052] In addition to temperature control, the drawing speed of the wire drawing machine is also very important. Usually, the drawing speed of the wire drawing machine is controlled within the range of 10-12m / min, which can ensure that the size and diameter of the glass fiber meet the requirements while ensuring production efficiency and stable quality.

[0053] During the drawing process, the length of the drawn fiber also needs to be controlled to avoid wire breakage, usually around 2400m-3600m. The control of this parameter directly affects the tensile strength and fineness of the glass fiber, and has an important impact on the performance and application of the final product.

[0054] In step three, before the glass fiber is processed in textile, it is first combed into 200-300 single fibers per bundle by a combing machine, and then the single fibers are processed into a web by mechanical web forming or air web forming. After the web forming process is completed, it is processed through a wire arrangement machine and a twisting machine for subsequent processing.

[0055] In step three, the glass fiber obtained from step two enters the textile processing stage, which is the key step to convert glass fiber into glass fiber yarn or glass fiber fabric. First, the glass fiber is processed by a carding machine to comb the fiber bundles into 200-300 single fibers per bundle. This process plays an important role in the arrangement, separation and arrangement of the fibers, which helps to improve the uniformity of the fibers and the quality of the spinning.

[0056] Next, the single fibers are processed into a web. There are two common web forming methods, one is mechanical web forming and the other is air web forming. In mechanical web forming, the single fibers are passed through a special mesh system, interlaced and interlocked to form a stable web structure. In air web forming, the single fibers are ejected into a high-speed airflow, through which the fibers are interlaced and deposited on a collecting surface to form a fiber web.

[0057] After the web-forming process is completed, the next step is the wire-forming machine and the twisting machine. The wire-forming machine stretches the web-forming glass fibers to make the fibers more uniform and enhance their strength and stability. Then, the twisting machine twists the fibers together. This process can be done in different twisting methods according to needs, such as S twist, Z twist, etc. The twisted fibers form slender glass fiber yarns.

[0058] Finally, the glass fiber gauze or glass fiber fabric needs to be sized. Sizing is a binder that can increase its strength, flexibility and durability by impregnating the glass fiber gauze or fabric. The sizing agent can be selected according to the specific application requirements. For example, the sizing agent used for reinforcement materials may be compatible with the resin to achieve a better bonding effect when preparing composite materials.

[0059] In step 4, the preheating temperature is 160-180 degrees Celsius, the preheating time is 15 minutes to 30 minutes, the hardener is one of epoxy resin or acrylic acid, the reheating temperature is 180-230 degrees Celsius, and the reheating time is 5 minutes to 20 minutes.

[0060] In step 4 of manufacturing environmentally friendly glass fiber filter materials, hardening treatment is a crucial step. First, the glass fiber that has been treated with textile sizing in step 3 needs to be preheated. The purpose of preheating is to increase the temperature of the glass fiber so that it is easier to absorb and fix the hardener before it is coated with the hardener. The preheating temperature ranges from 160-180 degrees Celsius, and the preheating time is usually 15min-3min, which can ensure that the glass fiber reaches the ideal preheating state.

[0061] After preheating, the next step is to apply a hardener to the surface of the glass fiber. The hardener is an important material that can form a solid structure when heated again, enhancing the hardness and durability of the glass fiber product. The hardener can be selected from materials such as epoxy resin or acrylic, which have good adhesion and high temperature resistance and can effectively cure glass fiber products. The following table compares the performance of glass fibers after being treated with different bonding components.

[0062]

[0063]

[0064] The bonding film-forming agent is the most important component in the glass fiber sizing. It has a decisive influence on the processing properties of glass fiber and the performance of FRP products. It contains a large number of functional genes that can react with glass and unsaturated resins, and can greatly improve the mechanical properties and processing properties of glass fiber.

[0065] After the hardener is applied, the glass fiber enters the heating equipment again for reheating. The reheating temperature is usually between 180-230 degrees Celsius, and the reheating time is about 5min-20min. This step is to fully cure the hardener and ensure that it is fully combined with the glass fiber to form a strong fiber structure.

[0066] Finally, after the reheating is completed, the glass fiber product is removed from the heating device and allowed to cool naturally to room temperature. This completes the manufacturing process of the environmentally friendly glass fiber filter material. These processes are carefully designed to ensure that the quality and performance of the glass fiber products meet the expected requirements, enabling them to play an important role in the field of environmental protection. Through these process steps, the glass fiber filter material produced has excellent filtering performance, corrosion resistance and high temperature resistance, and can be widely used in the fields of industrial waste gas treatment, water treatment, and environmental protection, making a positive contribution to improving environmental quality.
