The anti-corrosion means of PPH storage tank are cathodic protection and coating protection. Coating protection can be divided into two ways, namely, internal anti-corrosion treatment and external anti-corrosion treatment of PPH storage tank. For oil storage or product oil storage tanks, the required performance of anti-corrosion coating in the tank is electrostatic conduction. Therefore, in the process of anti-corrosion treatment of storage tanks, electrostatic conductive coatings are used for anti-corrosion treatment of storage tanks. The treatment of anti-corrosion coating outside the tank is to combine the anti-corrosion performance, weather resistance and aesthetic performance of the tank. In the design of anti-corrosion coating for PPH tank, the temperature resistance characteristics between anti-corrosion coatings must be considered, which is interchangeable. In the alkyd anti-corrosion coating, direct combination use must be avoided. This is because of chemical reaction with zinc powder. Cathodic corrosion protection of storage tank includes impressed current cathodic protection of storage tank bottom plate and protection treatment of storage tank ponding layer anode. Cathodic corrosion protection of storage tank is divided into impressed current cathodic protection on the outside of the bottom plate of the storage tank, and protective treatment on the anode of the ponding layer in the tank.

PPH mixing tank is made by seamless extrusion winding technology. Pipe orifice, inner weld and outer weld are all processed by automatic extrusion unit equipment, which is superior, stronger and lower than plastic tanks made by traditional technology. It is necessary to use electric heating to melt and extrude the particles onto the steel mold, which consumes a lot of power. The PP storage tank only has the power of the welding gun, so it consumes less power; The PPH mixing tank is welded with a large extrusion electric heating drag gun, which consumes a lot of power. The PP storage tank uses a small manual drag gun, which consumes less power. PPH reaction kettle uses PPH spiral extrusion and winding unit to process PPH granules into tank body forming process. The system adopts the process of hot melting PPH particles, extruding them, and then winding them onto steel dies to form cans. PPH reaction kettle has the characteristics of good integrity, uniform thickness, corrosion resistance, seamless, aging resistance and good leakage resistance.

During the processing of PPH winding tank, there are three core points: tank body fabrication, internal and external weld welding, and manhole installation. These three core points will affect the integrity, aging resistance, leakage resistance, service life, mechanical strength and other properties of the tank. PPH granular material is melted on the spiral extrusion winding unit, and then the melted extrusion material forms a tank on the mold, and demoulding is carried out after the temperature is reduced to a certain degree, so as to ensure the integrity of the tank. However, the traditional processing method is plate butt welding to form a tank body. Since the z width of the plate is 2000 mm and the tank body height is generally more than 2000 mm, in actual processing, the tank body is formed by manual welding of sections of the tank body. Then, to be safe, a stiffening ring is added at the joint of the tank body. PPH winding tank is formed by direct processing of PPH particles, without secondary processing. Traditionally, particles are processed into plates, and then the plates are processed into tank bodies; In addition, the PPH winding tank has no problems of joints, welds and leakage, and the overall mechanical strength is far greater than that of tanks processed by traditional processes because of the need for chamfer welding.

PPH storage tank has the advantages of corrosion resistance, corrosion prevention, long service life, light self weight, high strength, safe transportation, convenient maintenance, etc. The working pressure of PPH storage tank is normal pressure, and the working temperature is PPH-10 ℃~120 ℃, and PVC-40 ℃~60 ℃. PPH storage tank has the advantages of one-step forming without welding joint, impact resistance, aging resistance, light weight, no leakage, acid and alkali resistance, long service life, and compliance with health standards. PPH storage tank has excellent chemical corrosion resistance, and has good corrosion resistance to inorganic acid, alkali and salt (except oxidizing media). Common PPH tank solutions include dilute sulfuric acid, hydrochloric acid, hydrofluoric acid, hydrogen peroxide, phosphoric acid, ammonia, etc. Rotational plastic anti-corrosion PP storage tank has great advantages in large size, large capacity and large volume products. Although the volume is large, it only maintains the characteristics of one-time molding integrity, which is beyond the reach of other storage tank processes. Compared with the traditional anti-corrosion storage tank, the price is low and the performance price ratio is high.

When the storage tank made of polyethylene is produced and processed again, it does not need to use traditional welding, so its volume will be larger when it carries liquid. Because the HDPE storage tank does not need to be welded, so there is no weld. When it is used again, it does not need to worry about instability due to too much carrying liquid. Generally speaking, most storage tanks have a stability coefficient. The reason why the stability performance of storage tanks is different is that the performance of raw materials used is different. If the materials used are poor, even if the process is good, the stability performance is not guaranteed. When selecting raw materials for storage tanks, the first thing we should do is to check the quality certificate and inspection report of the raw materials. After checking, all data can be put into production only if they meet the standards. Besides, plates are used at the top and bottom of the tank, so there are requirements for plates.

The main contents of cleaning the HDPE storage tank are as follows: at the end of each manufacturing, clean the surface of the HDPE container with fingers, and continuously clean the outside of the mechanical equipment with a large amount of water. Damage to the thermal insulation layer is strictly prohibited. According to the processing technology, the solution can be cleaned after a certain period of time. For a long time, more than 72 hours, machines and equipment should be cleaned again before class. It is forbidden to enter acid liquor into the bobbin of this commodity. If the cleaning box requires acid, do not use acid with pH<2. Once the acid enters the casing of this mechanical equipment, hydrogen effect will occur, and the surface will fall like a fish scale on a large scale. The general cleaning cylinder uses 2% of sodium hypochlorite solution and uses tap water to clean the cylinder. The HDPE tank shall be cleaned according to the requirements of Chinese standards. When entering the machine and equipment for cleaning, the water bottle should be padded at the bottom of the sponge pad to prevent special tools from falling in. Wear rubber shoes to prevent damage to the laminated glass. To sort out the actual staff, the records must be sorted out immediately to determine the work experience and the inspection and signature of the project.
