Problems solved by technology

[0002] The chemical pump is an energy-saving pump designed jointly by the whole country. The performance and technical requirements of the pump are designed according to the performance and size stipulated by international standards. Its advantages: the whole series of water conservancy performance is reasonable, the user has a wide range of choices, and the "back-opening" structure , convenient maintenance, efficiency and suction reach the international advanced level, widely used in industrial, urban water supply, drainage, irrigation and drainage of farmland, orchard, for transporting clean water or other liquids with physical and chemical properties similar to clean water, chemical pumps are used in In normal use, due to the different application fields of the pump body, it will be used in some industries with corrosive mesons. Therefore, in the normal processing of chemical pumps, paint will be applied on the surface of the pump body to ensure its corresponding beauty. At the same time, it can also prevent corrosion and improve the service life. However, since the chemical pump is in normal use, it will involve a certain amount of high-calorie fluid delivery, so the ultra-high-calorie fluid will cause the paint on the surface of the chemical pump to be subjected to extremely high temperatures. , it is easy to cause a certain amount of paint to fall off after being heated, so how to carry out surface treatment before spraying paint on the pump body of the chemical pump so that it can be combined with the paint better and prevent the paint from falling off at high temperature is a technical problem to be solved at present

Embodiment 1

[0015] A method for pretreatment of the surface of a chemical pump pump body before painting, comprising the following steps:

[0016] a. Remove the surface rust of the chemical pump to be painted until there is no visible rust on the surface;

[0017] b. Use clarified lime water to evenly spray the surface of the chemical pump after the rust removal above at a pressure of 1.5 MPa. After spraying evenly for 10 minutes, adjust the pressure to 1.0 MPa and continue spraying evenly for 10 minutes, then let it stand for 20 minutes, and then use boiling water. Carry out a surface rinsing, after rinsing, use a hot air blower to dry the surface moisture;

[0018] c Prepare the treatment agent A and heat it to 55°C. Use a brush to directly paint the treatment agent A on the surface of the chemical pump. After standing for 30 minutes, rinse it with boiling water, and then wipe the surface of the chemical pump with a dry cloth. Clean; the treatment agent A is made of the following ingre...

Abstract

The invention discloses a pre-treatment method for the surface of a pump body of a chemical pump before paint spraying. The pre-treatment method comprises the following steps that (a) rusty spots are cleared away; (b) the surface of the pump body is sprayed through clear limewater; (c) a treatment agent A is coated and brushed; (d) a treatment agent B is sprayed; and (e) the pump body is heated to be 40 DEG C, and then paint can be coated and brushed. The pre-treatment method for the surface of the pump body of the chemical pump before paint spraying is simple and convenient in technological process, the surface of the chemical pump is subjected to pre-treatment through the scientific and reasonable method, and it is ensured that the surface of the chemical pump is clean and free of blots; and it is ensured that the paint can be firmly adhered to the surface of the chemical pump during subsequent paint spraying, so that safety and thoroughness are achieved, and adhesive force is high.
