Glass fiber white gold cloth is an inorganic material, which is not easy to be corroded,

Glass fiber white gold cloth is an inorganic material, which is not easy to be corroded, has good insulation effect, and has strong heat resistance and heat resistance. Let's learn about the acid attack and use temperature of glass fiber platinum cloth
Acid attack of glass fiber white gold cloth:
Glass fiber white gold cloth is generally considered to have good resistance to hydrochloric acid, acetic acid and nitric acid, and can resist the attack of phosphoric acid at low temperature. However, when aluminum phosphate is formed at high temperature, glass fiber white gold cloth will produce obvious shrinkage. When the temperature is higher than 540 ° C, it is necessary to avoid contact between refractory fiber and phosphoric acid.


Service temperature of glass fiber cloth refractory fiber:
For the glass fiber platinum cloth, the long-term service temperature is 1000-1250 ° C, and the melting temperature is above 1780 ° C, while the continuous service temperature of rock wool, slag wool, etc. is 600-700 ° C. The fibers will shrink and crush when the service temperature exceeds their service temperature. For this reason, these materials cannot be used as the working lining of high-temperature furnaces.
