Polyurethane Elastomer TDI System Casting Machine for CPU Scrapers
Polyurethane elastomer casting machine is mainly used to produce polyurethane products, such as polyurethane puff, insole, sole, rubber roller, rubber wheel and other products. It is mixed with two different polyurethane raw material A and B and casting into the mold for molding. Compared with manual pouring, the polyurethane elastomer casting machine has stable pouring quality and higher production efficiency.
The polyurethane elastomer casting machine can be used for the production of CPU products such as TDI, MDI and other prepolymer amine cross-linking or alcohol cross-linking systems. Compared with traditional manual casting, the polyurethane elastomer casting machine has the following advantages:
1. The ratio is accurate and the measurement is stable. The high-precision temperature and pressure-resistant metering pump and precision transmission are used to adjust and display the device. The measurement accuracy is within 1%.
2. Mix evenly without bubbles. A special structure of high-speed mixing head is used. When the viscosity and ratio of the two components are greatly different, the mixing can be ensured evenly, so that the products produced are free of bubbles.
3. The temperature is stable, accurate and controllable.

Polyurethane scraper has high abrasion resistance, aging resistance, solvent resistance, and long service life. According to the different use environment, the hardness of the product is widely selected: ShoreA40-ShoreA95, choose different hardness and different materials for different working conditions. Polyurethane squeegee is also called PU squeegee. It is used on coal and chemical conveyor belts to remove adhered ash powder and powder materials, such as coal transportation, fertilizer transportation, and sand transportation.
