Introduction:
PP is a kind of thermoplastic resin made from the polymerization of propylene. There are three configurations: equivalence, irregularity, and internorm. Industrial products are mainly composed of equivalence. Usually translucent colorless solid, odorless non-toxic. Due to the structured and highly crystallized structure, the melting point is as high as 150 degrees heat resistant, and the product can be steam sterilized as its outstanding advantages. Density 0.90 g/cm3, corrosion resistance, tensile strength 30 MPa, strength, rigidity and transparency are better than polyethylene. Features: non-toxic, no ignorance, low density, strength, stiffness, hardness and heat resistance are better than low-pressure polyethylene, can be used at about 80 degrees. It has good electrical performance and high frequency insulation is not affected by humidity, but it becomes brittle at low temperatures. Not wearable, easy to aging. Suitable for general mechanical parts, corrosion resistant parts and insulation parts. Common acid, alkali organic; Rongqi, which has little effect on it, can be used in food utensils. Suitable for chemical, treatment, pharmaceutical and other industries of corrosion media, dangerous liquid storage.

Principle:
In the inner layer, the reaction solvent can be used for stirring reactions. The sandwich can be used for cyclic heating or cooling reactions with different cold heat sources(refrigerants, hot water or hot oil). Through the reaction kettle sandwich, inject a constant temperature(high temperature or low temperature) thermal media or cooling media, heating or cooling the material in the reaction tank at a constant temperature. At the same time, the stirring reaction can be carried out under normal pressure or negative pressure according to the requirements of use.
Features: PP mixing tank applied to micropositive pressure and slightly higher than room temperature and strong corrosive medium of the ideal reaction cooker, and has the advantages of low cost, light weight, convenient installation and strong corrosion resistance.
1, product specifications: 0.5-30 cubic meters can be customized;
2, operating pressure: micropositive pressure;
3, operating temperature: PP-10 °C ~ 80 °C;
4, strong corrosion resistance, convenient operation, long service life;
5, light weight: for the equipment transportation, installation, maintenance are more favorable.
