The invention relates to a scale remover for condensation equipment and a preparation method thereof. The scale remover is composed of 15% to 30% of a dissolving agent, 2% to 5% of a penetrating agent, 1% to 5% of a corrosion inhibitor, and a cosolvent 10% to 30%, purified water 20% to 30%, and the rest is ethanol, in terms of mass percentage; the dissolving agent is selected from oxalic acid, citrate, ascorbic acid, salicylic acid and glacial acetic acid, and the penetrant is selected from diethyl succinate Among esters, ethylene glycol monobutyl ether and dioctyl sulfosuccinate sodium salt, the corrosion inhibitor can be hexamethamine, aniline, diethylthiourea or rhodin, and the cosolvent can be p-benzoic acid, urea, Cyclohexanone, acetamide and sodium salicylate. The invention combines the above-mentioned raw materials and utilizes the combination effect to make them have strong descaling ability and fast descaling speed, less corrosion to equipment, low price, can save a lot of cleaning costs, and improve equipment operation level and energy utilization The level and production efficiency have greatly reduced the cost of producing products.

The invention belongs to the technical field of hollow object cleaning devices, and particularly discloses a bottle body cleaning device. The bottle body cleaning device comprises a rotation rod and acleaning brush. The cleaning brush is in a cylinder shape, and a blind hole for containing the rotation rod is formed in one end of the cleaning brush. A holding handle is fixedly connected to one end of the rotation rod, and a through hole communicating with the blind hole is formed in the side face of the cleaning brush. A cleaning part is arranged in the through hole and comprises a flexible rod and a flexible cleaning layer. The flexible rod is in sliding connection with the through hole. The flexible cleaning layer covers the outer surface of the cleaning brush and is fixedly connected with the edge of the through hole. The flexible cleaning layer is fixedly connected with a tension spring, and the other end of the tension spring is fixedly connected with the inner wall of the through hole. The inward end of the flexible rod is in a wedge shape. The position, corresponding to the through hole, of the surface of the rotation rod is provided with an elastic extrusion part. A limiting boss is arranged at the opening end of the cleaning brush, and the end, away from the holding handle, of the rotation rod is provided with an annular boss matched with the limiting boss.

The invention relates to a chemical cleaning material, and in particular to a special chemical cleaning material for removing scale of a water heater. The special antiscaling agent for the water heater is characterized by being formed by mixing components A, B, C and C, wherein the component A is an acidic antiscaling component which is 70 to 95% in percentage by weight; the component B is an adhesive which is 2 to 8% in percentage by weight; the component C includes a metal ion chelating agent and a curing agent, which is 2 to 20% in percentage by weight; and the component D is a corrosion inhibitor, which is 1 to 5% in percentage by weight. With the adoption of the prescription, the special antiscaling agent for the water heater provided by the invention has the advantages of being relatively low corrosion to metal, and high antiscaling performance; and moreover, the special antiscaling agent can be manufactured in a certain shape, and the dimension is in line with that of a sewage draining port of the water heater; and the antiscaling agent can be directly added to the water heater through the sewage draining port; the problem that the powdered material or liquid is hardly added can be solved; the antiscaling agent is convenient and quick to use, and the operation is simple to carry out.

The invention discloses a scavenger for clearing away PVC (polyvinyl chloride) polymer in a top condenser of a polymerization kettle, which comprises the following components by weight percentage: 60-80% of a chelator, 1-5% of a penetrant, 0.5-3% of a surfactant, 15-25% of a cosolvent and the balance of acetone or glycol. The scavenger is prepared by the steps of adding raw materials such as the chelator, the penetrant, the surfactant, the cosolvent and the like in a reactor, stirring, adding acetone or glycol after the raw materials are fully dissolved, and stirring uniformly; and finally filling. The scavenger for clearing away PVC polymer provided by the invention has strong chelation dissolving capacity, high dissolving rate, almost no corrosion to all metals and high descaling capacity, is convenient to use and fast in action, and does not affect the continuous normal production of enterprises. The scavenger has remarkable social and economic benefits.

The invention provides an alloy material with anti-fouling application, which comprises the following components in mass percentage: Cu: 45%-55%, Zn: 22%-35%, Ni: 11%-25%, Sn: 2 % to 4%, Al: 2% to 3.5%, Mn: 1.5% to 3.5%, Au: 0.01% to 0.1%. The invention also discloses a preparation method thereof, which includes selecting smelting raw materials, performing batch calculation, and selecting smelting tools and smelting processes for smelting. According to the invention, different metal element proportions are then alloyed to form alloy materials, so as to prevent fouling of equipment in the industrial production process, improve thermal efficiency of equipment, and reduce production costs.

The invention discloses a preparation method of a beer bottle sterilizing detergent based on a microcrystalline cellulose / silver composite material. A nanocrystalline cellulose suspension prepared byan enzymatic method is mixed with silver nitrate and then a hydrothermal synthesis reaction is carried out to obtain a nano-silver loaded nano microcrystalline cellulose suspension, a biological surfactant, alkali and other raw materials are added and uniform mixing is carried out to obtain the beer bottle sterilizing detergent. The beer bottle sterilizing detergent prepared by the preparation method not only has the advantages of strong detergency, good anti-dirt redeposition ability, easiness for rinsing and removing dirt, and good cleaning effect on beer bottles, and can reduce scaling of equipment and is favorable for smooth running of a whole system, but also synchronously achieves sterilization and disinfection of the beer bottles with good bactericidal effect, and effectively improves the hygiene performance of the cleaned beer bottles.
