Pkab specification:
Qhov tsos:Tsis muaj xim thiab needlelike siv lead ua los yog hmoov dawb.
Siv:
- Bisphenol S molecule muaj ob pawg hydroxyl thiab muaj zog electron rho tawm sulfone, acidic dua lwm cov phenols.
- Bisphenol S feem ntau yog siv los kho tus neeg sawv cev.Kev kho tus neeg sawv cev tuaj yeem tsim rau cov khoom siv raw nrog bisphenol S A.
- Nws muaj kev ua haujlwm kub zoo, lub teeb ua haujlwm thiab oxidation tsis kam,raw khoom ntawmpolycarbonate, epoxy resin thiab polysulfide, polyether sulfone, polyether resin thiab lwm yam.
- Kuj tseem siv tau rau hauv kev tsim cov ntaub ntawv xim xim, kev yees duab sib piv, cov khoom siv thermo rhiab heev (tsim tawm), cov khoom siv niaj hnub surfactant thiab cov deodorant, thiab lwm yam tuaj yeem siv los ua cov tshuaj ntxiv hauv cov tshuaj plating, tawv tanning tus neeg saib xyuas, disperse dye dyeing ntawm qhov kub thiab txias. hardening accelerator, phenolic resin, resin, nplaim retardant, thiab lwm yam. Thiab intermediates ntawm tshuaj tua kab, dyes, auxiliaries, kuj tuaj yeem siv ncaj qha rau hauv cov xim, tawv hloov tus neeg sawv cev, tus neeg sawv cev ntawm lub teeb hlau plating.
