explain:
Jinquan nano polyphenylene sulfide independently developed HNTs nano materials and their surface modification technology on the basis of SiOx in the early stage to produce nanocomposite short fibers
characteristic:
Compared with pure polyphenylene sulfide, it has higher oxidation resistance, good mechanical properties, excellent chemical corrosion resistance, flame retardant, high temperature resistance, insulation and other physical and mechanical properties. The oxidation induction temperature is increased by 10 ~ 15 ℃, the decomposition temperature is increased by 4 ~ 6230 ℃, and the strength retention rate for 72h is ≥ 90%; In the critical boiling acid-base solution, the fiber has no damage and the strength retention rate is 100%
Purpose:
Used for flue gas dust removal in the field of environmental protection and dust removal: dust removal of high temperature and high corrosion tail gas in heavy industries such as coal-fired boilers, thermal power generation and waste incineration
