High temperature and corrosion resistant air duct, also known as high temperature resistant silicone hose, is made of glass fiber cloth, non-combustible polymer material, silicone rubber, high elastic steel wire, high temperature wire, and vulcanized and compounded at 300 ℃. So how to distinguish the quality of high-temperature air duct in the face of products with inferior quality in the market? As a professional ventilation pipe manufacturer, I will give you a brief introduction below:
- Look at the surface: check the exterior and interior surfaces. The surface of highquality, hightemperature-resistant and corrosion-resistant air ducts should be very smooth, no smudges, no wrinkles, no rough and uneven points.
- Look at the pitch: The highquality, hightemperature resistant silicone hose elastic steel wire and glass fiber thread have the same pitch, and they are evenly wound.
- Look at bending: Highquality, hightemperature resistant silicone hoses bend freely and are elastic, while inferior products have poor elasticity and are not easy to bend.
- Look at the material: Good high temperature, temperature and corrosion resistance air duct is made of high quality silicon rubber, which has better temperature and corrosion resistance. The glass fiber wire wound on both sides of the elastic steel wire is made of the same material as the base cloth, which also has the effect of temperature resistance and flame retardant. Inferior high temperature air ducts are usually ordinary nylon threads used for cost savings.
The above is the main criteria for judging the quality of high temperature resistant silicone ventilation hoses. I hope that everyone can buy high quality products.
