TF-MCA Halogen-free Flame Retardant Melamine Cyanurate (MCA)
Taw qhia
Melamine Cyanurate (MCA) yog ib qho kev ua haujlwm siab halogen-dawb ib puag ncig nplaim retardant uas muaj nitrogen.Nws yog dav siv hauv kev lag luam plastics ua cov nplaim hluav taws.
Tom qab sublimation tshav kub nqus thiab kub decomposition, MCA yog decomposed rau nitrogen, dej, carbon dioxide thiab lwm yam gases uas tshem tawm cov reactant cua sov kom ua tiav lub hom phiaj ntawm nplaim retardant.Vim yog qhov kub sublimation decomposition kub thiab zoo thermal stability, MCA tuaj yeem siv rau feem ntau ntawm cov khoom ua haujlwm.

Yam ntxwv
MCA yog cov nplaim hluav taws muaj txiaj ntsig zoo vim nws cov ntsiab lus nitrogen siab, ua rau nws xaiv zoo rau cov ntaub ntawv uas yuav tsum tau ua kom tsis muaj hluav taws xob tsawg.Nws cov thermal stability, ua ke nrog nws cov toxicity tsawg, ua rau nws yog ib qho kev xaiv rau lwm cov nplaim retardants xws li brominated compounds.Tsis tas li ntawd, MCA tseem pheej yig thiab yooj yim rau kev tsim khoom, ua rau nws xaiv kev lag luam rau kev siv loj.
Daim ntawv thov
MCA yog siv los ua cov nplaim hluav taws kub nyhiab hauv ntau cov ntaub ntawv, suav nrog polyamides, polyurethanes, polyesters, thiab epoxy resins.Nws yog tshwj xeeb tshaj yog pab tau nyob rau hauv engineering plastics, uas yuav tsum tau high-kub kev ua tau zoo thiab tsis tshua muaj flammability.MCA tseem tuaj yeem siv rau hauv textiles, xim, thiab txheej txheej los txhim kho nplaim taws.Hauv kev tsim kho kev lag luam, MCA tuaj yeem muab ntxiv rau cov khoom siv hauv tsev xws li ua npuas ncauj rwb thaiv tsev kom txo tau qhov sib kis ntawm hluav taws.
Ntxiv rau nws siv los ua cov nplaim hluav taws, MCA muaj lwm yam kev siv thiab.Nws tuaj yeem siv los ua tus neeg sawv cev kho rau epoxies, thiab nws tau pom tias muaj txiaj ntsig zoo los txo cov pa luam yeeb tawm thaum hluav taws kub, ua rau nws muaj txiaj ntsig zoo hauv cov khoom siv hluav taws kub.
