Khoom siv
Tetrabromophthalic anhydride yog cov nplaim hluav taws kub hnyiab nrog cov ntsiab lus bromine siab.
Reactive nplaim retardants: Nws tuaj yeem siv los ua cov nplaim hluav taws kub nyhiab, cuam tshuam nrog cov polymers los ua covalent bonds, yog li txhim kho cov nplaim hluav taws xob ntawm cov polymers. Nws yog feem ntau siv nrog cov ntaub ntawv xws li polyester resin, epoxy resin, unsaturated polyester, thiab polyurethane.
Additive Nplaim Retardants: Nws tuaj yeem ua haujlwm sib koom ua ke nrog lwm cov nplaim hluav taws, xws li antimony trioxide, raws li cov nplaim hluav taws xob ntxiv hauv cov thermoplastics xws li polystyrene (PS), polypropylene (PP), polyethylene (PE), thiab ABS resins los txhim kho lawv cov nplaim hluav taws.
Tsis tas li ntawd, FHT-4 derivatives tuaj yeem siv rau hauv kev kho cov nplaim hluav taws xob ntawm cov xov hlau, cables, thiab cov ntaub plaub.

FAQ
Q: Puas yog TBPA Toxic?
A:Kev kis tus kab mob TBPA tuaj yeem ua rau cov tsos mob xws li hnoos, txham, ua pa ua pa, dermatitis, thiab khaus qhov muag.
nws reacts exothermically nrog dej. Thaum cov tshuaj tiv thaiv feem ntau qeeb, nws tuaj yeem ua kom muaj zog yog tias cov cua sov hauv zos nrawm nrawm rau nws.
Q: Puas yog tetrabromophthalic anhydride xa tawm raws li cov khoom lag luam lossis cov khoom txaus ntshai?
A: Thaum nws raug xa tawm raws li cov khoom dav dav, peb tuaj yeem muab daim ntawv qhia txog kev thauj mus los.
