Product Description:
1.High silica fiber （SiO2>96%）Products, It is a kind of high-temperature resistant inorganic fiber product, with a softening point of 1500 ℃, which can be used in 900-1000 ℃ environment for a long time, and can withstand thousands of degrees of airflow erosion in an instant. Therefore, it can be used for spacecraft anti thermal ablation materials, high-temperature heat insulation and fireproof materials, high-temperature gas dust collection, liquid filtration, metal melting, filtration and purification, etc; High silica fiber products also have excellent chemical stability and good dielectric properties. They can be used as high temperature resistance insulation structure integrated multifunctional materials.
2. High silica products have excellent heat resistance, < / strong > chemical stability, good electrical insulation, pre soft texture and easy design and processing; SiO2≥96%； Thermal shrinkage ≤ 8% (sintered cloth ≤ 3%); Heat vector ≤ 3%
3. High silica products mainly include the following series:
A. High silicon oxygen thermal insulation fireproof surface cloth series
B. High silica refractory fiber cloth series
C. High silica fiber felt series products (non-woven felt and staple yarn)
D. High silica network cloth
E. High silicon oxygen sewing thread / braided thread / rope / belt / sleeve, etc
Product purpose:
Compared with quartz fiber, ceramic fiber and other high-temperature resistant inorganic fibers, high silica fiber has the advantages of low cost, stable performance and safe use. In recent years, the demand for high silica products is increasing. High silica fiber cloth has been widely used in the United States and Europe, and the amount is increasing; In China, high silica products mainly serve the military industry and civil use is still in its infancy. However, with the development of China's industry, the demand is also increasing day by day:
A. High silicon oxygen thermal insulation fireproof surface cloth series: the woven fabric is widely used as thermal ablation resistant materials for rockets, missiles and spacecraft, with high temperature resistance and thermal insulation.
B. High silica refractory fiber cloth series: high temperature resistant thermal insulation and insulating materials; Fireproof clothing, fire curtain, special high-temperature gloves and other high-temperature gas filtration.
C. High silica fiber felt series products (non-woven felt and staple yarn): thermal insulation products, used for high-temperature gas filtration in automobile and industrial machinery manufacturing.
D. High silica mesh cloth: filtration in metallurgical industry.
E. High silicon oxygen wire / rope / with sleeve, etc.: sheath of ultra-high temperature wire and cable.
