Embodiment 1

[0054] A kind of rapid descaling anti-corrosion environmental protection descaling agent, the preparation formula and ratio are: oxalic acid Kg, citric acid 2Kg, malic acid 3Kg, tannic acid 2Kg, sodium polyacrylate 2Kg, dispersant 0.05Kg, sodium hexametaphosphate 10Kg, deionized water 50Kg; wherein, the dispersant is potassium sorbate, benzoic acid, propionic acid in a mass ratio of 1:0.5:2.5 mixed.

[0055] Among them, the sources of different raw materials can be described as follows: sodium polyacrylate was purchased from Henan Zhenya Chemical Products Co., Ltd., and its relative molecular weight is 2000-5000 low molecular weight sodium polyacrylate, industrial grade, model 445N, the goods number is 20181213; the CAS number of oxalic acid is 144-62-7, which is industrial grade, purchased from Jinan Dehou Chemical Co., Ltd.; the CAS number of citric acid is 5949-29-1, which is industrial grade, purchased from Jinan Yuanfei Weiye Chemical Co., Ltd The CAS number of malic acid is ...

Embodiment 2-14

[0062] Example 2-14 of the rapid descaling of the anti-corrosion environmental protection descaler formulation ratio and Example 1 is different, specifically referred to In Table 1, a rapid descaling anti-corrosion environmental protection descaling agent preparation method with Example 1.

[0063] Table 1 Embodiment 1 of the descaler formulation ratio

[0064]

Embodiment 15

[0066] The difference between Example 15 and Example 12 is: a method for preparing a rapid descaling anti-corrosion environmental protection descaler, comprising the following steps:

[0067] S1 Oxalic acid, citric acid, tannic acid and malic acid are crushed and then screened over 700 mesh and set aside;

[0068] S2 mixed the oxalic acid, citric acid, tanninic acid and malic acid and deionized water obtained in S1 for 20 min to give solution A;

[0069] S3 added sodium polyacrylate to solution A, heated to 90 ° C and stirred for 40min, then cooled to room temperature to give solution B;

[0070] S4 in solution B of S3 was added to sodium hexametaphosphate, potassium sorbate, benzoic acid, propionic acid, stirred and mixed.

[0071] Otherwise with Example 12.

Abstract

The invention discloses a quick descaling antiseptic and environment-friendly descaling agent and its preparation method and application. The descaling agent comprises the following raw materials in parts by weight: 3-40 parts of oxalic acid; 2-20 parts of citric acid; 3-20 parts of malic acid 25 parts; 2-12 parts of tannic acid; 2-15 parts of sodium polyacrylate; 0.05-1 part of dispersant; 10-40 parts of preservative; 50-200 parts of deionized water. The preparation method of the descaling agent is as follows: S1 oxalic acid, citric acid, tannic acid and malic acid are crushed and sieved; S2 is mixed with the mixture of S1 and deionized water to obtain solution A; S3 is added sodium polyacrylate to solution A, Heat and cool to obtain solution B; S4 Add preservative and dispersant to solution B, and mix well. The descaling agent of the invention can be used for descaling of central air-conditioning cooling towers, water treatment pipelines, boilers, etc., and has the advantages of low environmental pollution, high descaling efficiency and certain sterilization rate.

Description

Technical field [0001] The present invention relates to the technical field of chemical descaling, more particularly, it relates to a rapid descaling anti-corrosion environmental protection type descaling agent and preparation method and application thereof. Background [0002] The cooling tower of the central air conditioner is exposed to the air during daily use, and there are many suspended solids, dust and impurities in the air that will continue to accumulate in the cooling tower, so the cooling tower will have dirt precipitation, and a large number of biological algae mud will also grow in the cooling water system, resulting in blockage. Secondly, in the winter, the cooling tower rarely needs to be used, and the cooling tower will accumulate a lot of water, and the water in the cooling tower will cause corrosion to the interior of the cooling tower, and over time, it will accumulate corrosive materials, resulting in serious local corrosion and affecting the thermal conducti...
