Alkaline descaling agent is more economical, but it is cumbersome to use and requires specific conditions; liquid inorganic acid descaling agent is more economical, but it is highly corrosive and not convenient for storage and transportation
CN1068801A discloses copolymerization or terpolymer based on acrylic acid and maleic acid as silica scale inhibitor, although replace inorganic acid with organic acid, the cost is high; The descaling agent mixed with urotropine, because oxalic acid and calcium ions can generate calcium oxalate precipitation, thereby increasing the difficulty of descaling; Water tank descaling cleaner, in which nitrilotriacetic acid is insoluble in water, has low toxicity, and is difficult to configure and apply

Embodiment 1
[0027] A high-efficiency water-retaining bactericidal and descaling agent, prepared from the following weight percentages of raw materials: polyvinyl alcohol 3w / %, lauroyl arginine ethyl ester hydrochloride 8w / %, alkylphenol polyoxyethylene ether 55w / %, sodium bicarbonate 5w / %, sodium chloride 6w / %, citric acid 15w / %, ethanol 8w / %.
[0028] Preparation:
[0029] S1. After grinding polyvinyl alcohol, lauroyl arginine ethyl ester hydrochloride, sodium bicarbonate, and sodium chloride separately, pass through a 1000 mesh sieve;
[0030] S2. Weigh each raw material component of S1 according to weight percentage, and mix it evenly;
[0031] S3. Weigh alkylphenol polyoxyethylene ether, citric acid, and ethanol by weight percentage, and mix them evenly;
[0032] S4. Heat the S3 liquid mixture to 60°C, add the solid mixture in step S2, and mix and dissolve; leave it at room temperature for 3 hours to obtain the high-efficiency water-retaining sterilizing and descaling agent.
Embodiment 2
[0034] A high-efficiency water-retaining bactericidal and descaling agent, prepared from the following weight percentages of raw materials: polyvinyl alcohol 2w / %, lauroyl arginine ethyl ester hydrochloride 10w / %, alkylphenol polyoxyethylene ether 50w / %, sodium bicarbonate 10w / %, sodium chloride 5w / %, citric acid 15w / %, ethanol 8w / %.
[0035] The preparation method is the same as in Example 1.
Embodiment 3
[0037] A high-efficiency water-retaining bactericidal and descaling agent, prepared from the following components in weight percentage: polyvinyl alcohol 5w / %, lauroyl arginine ethyl ester hydrochloride 5w / %, alkylphenol polyoxyethylene ether 52w / %, sodium bicarbonate 8w / %, sodium chloride 10w / %, citric acid 10w / %, ethanol 10w / %.
[0038] The preparation method is the same as in Example 1.

Abstract
The invention discloses an efficiently water-retaining and sterilizing scale remover. The efficiently water-retaining and sterilizing scale remover is prepared from raw materials including, by weightpercentage, 2-5 w / % of polyvinyl alcohol, 5-10% of ethyl lauroyl arginate hydrochloride, 50-60% of alkylphenol ethoxylate, 5-10% of sodium bicarbonate, 5-10% of sodium chloride, 10-20% of citric acidand ethyl alcohol as balance. Through the surface active bactericidal ability of amino acids, the scale removing and corrosion inhibiting ability of citric acid and alkylphenol ethyoxylate, and the film forming and water retaining effects of polyvinyl alcohol, the efficiently water-retaining and sterilizing scale remover can strip, moisturize and disperse dirt and corrosives covering the surface of metal or plastics into absorption liquid to achieve the aim of cleaning as well as elimination of bacteria and microorganisms in solution and on the surface of metal and plastics. The efficiently water-retaining and sterilizing scale remover has the advantages of simple production processes, low production cost, safety production and application, environmental protection, high efficiency and thelike and is convenient to transport and use and high in water retaining, bactericidal and scale-removing effects.
Description
Technical field [0001] The invention belongs to the technical field of cleaning agents, and more specifically, relates to a high-efficiency water-retaining sterilization and descaling agent used in a water-cooled heat exchange system and a preparation method thereof. Background technique [0002] With the rapid development of modern industry, the use of cooling water is increasing, but at the same time, the scale existing in a large number of circulating exchange equipment cannot be scientifically cleaned, resulting in energy consumption and environmental damage. At the same time as damage, the operating efficiency is reduced. During the heat exchange process of the cooling water, crystals are continuously deposited on the surface of the heat exchanger to form scale, which not only affects the heat exchange efficiency but also increases energy consumption, and even stops and stops production due to insufficient cooling water flow and reduced pressure . However, traditional clea...
