Product characteristics and structure of PP pickling tank

Advantages of PP pickling tank: acid resistance, alkali resistance and chemical corrosion resistance;

Pickling tank is a container used for chemical treatment to remove rust, oxide scale and other sundries on the surface of various metal parts. Alkali resistance, acid resistance, high temperature resistance, good corrosion resistance, can store all kinds of liquids.

According to the concentration and temperature of corrosive medium, different anti-corrosion material resins (including ordinary poly resin, epoxy resin and vinyl ester resin) are selected to cooperate with alkali free glass felt or glass fiber cloth for production.

1. Acid, alkali and chemical corrosion resistance;

2. It is composed of degreasing agent, dissolution accelerator, high-efficiency corrosion inhibitor and fog inhibitor, and the degreasing, rust removal and oxide scale removal are completed in one step;

3. The deoxidization speed is fast, the efficiency is high, the corrosion to the metal matrix is small, and the corrosion inhibition rate is high; 4. There is no acid mist during cleaning operation, which greatly improves the production environment

Pickling tanks are widely used in metallurgical, electroplating and other industries:

1. It is used for pickling the surface of various copper and aluminum metals such as titanium nickel alloy, stainless steel and so on;

2. Promote the removal of stubborn oxide scale on the metal surface, especially the high-temperature oxide scale generated in the process of hot rolling, annealing and tempering, and prevent the generation of hydrogen embrittlement;

3. Reduce the corrosion rate of metal, double the service life of acid solution, and finally make the product surface clean and form a uniform silver white matte structure.

1、 Tank structure design

The horizontal stiffener, vertical stiffener and support bar at the bottom of the groove shall be divided according to the size of the groove, and the plate thickness of the groove bottom and groove wall shall be checked according to the strength and stiffness requirements, so that the divided size can meet the requirements of plate thickness of 4mm. Then, the section coefficient and moment of inertia of horizontal stiffener, vertical stiffener and groove bottom support bar are calculated respectively according to the size of division and the requirements of strength and stiffness., Select the appropriate section steel according to the section coefficient and moment of inertia of various sections.

2、 Pickling tank heating

The liquid in the pickling tank is processed with a plastic King capillary heat exchanger to heat hot water with a heat source greater than 85 ℃ (the hot water is heated by steam). The plastic King wool thin tube heat exchanger is vertically placed on the inner wall side of the pickling tank, and the hot water is injected into the capillary of the heat exchanger. Under the conduction of the pipe wall, the acid washing liquid is heated quickly and stably, and the cooled condensate is led out of the capillary to the pickling tank.
