Nplaim taws retardant mechanism ntawm melamine cylamurate

Melamine Cyalurate(MCA) yog ib feem siv ib puag ncig tus qauv retardant, pa-66), PBTTYREANE, PBT, PBT), PBT), Polyolefin thiab Halogen- Dawb xaim thiab cable. Nws cov nplaim paj zoo heev retardant cov khoom, muaj kev lom zem tsawg thiab zoo thermal stability tau ua rau nws dav muaj kev txhawj xeeb thiab thov rau hauv cov khoom siv hluav taws xob, tsheb thiab kev tsim kho.

Melamine cyalurate yog ib qho compound tsim los ntawm cov tshuaj tiv thaiv ntawm melamine thiab cyanuric acid. Cov qauv molecular lattice tsim los ntawm hydrogen tsev ntawv muaj cov ntsiab lus nitrogen nplua nuj. Qhov no tso cai rau Melamine Cyanurate kom tso qee qhov nyiaj ntawm nitrogen thaum muaj kev sib kis tau kub, uas yog inhibiting kev sib kis taws. Nws cov qauv tshuaj txiav txim siab tias nws muaj qhov zoo thermal stability, tshuab lub zog thiab cov nplaim paj zoo heev retardant nyhuv.

Nplaim taws retardant mechanism ntawm melamine cylamurate

Cov nplaim taws retardant mechanism ntawm Melamine Cyalurate yog feem ntau tau cuam tshuam hauv nws cov yam ntxwv kub ntawm cov khoom siv roj carbon monoxide ntawm cov nplaim hluav taws. Tshwj xeeb, nplaim taws retardant nyhuv ntawm MCA tuaj yeem txheeb xyuas los ntawm cov hauv qab no:

(1) Tso cov nitrogen rau inhibit cov pa oxygen

MCA molecules muaj ntau npaum li cas ntawm cov nitrogen hais. Thaum lub sij hawm cov txheej txheem cua sov, cov ntsiab lus Nitrogen yuav raug tso tawm los ua cov roj (feem ntau nitrogen roj). Cov pa roj nitrogen nws tus kheej tsis txhawb kev sib txuas, txo qhov ntsuas kub ntawm cov nplaim taws ib puag ncig, thiab yog li ua kom muaj kev sib txuas nrog cov kev sib txuas. Tus txheej txheem no yog qhov tseem ceeb los txhim kho cov nplaim hluav taws xob retardant thaj chaw ntawm cov khoom, tshwj xeeb tshaj yog nyob rau hauv cov kev mob siab.

(2) txhawb kev tsim cov txheej txheem carbonized

Thaum lub sij hawm pyrolysis cov txheej txheem, MCA yuav decompose thiab tsim cov txheej carbonized thaum thermal decomposition. Qhov no inert carbonized txheej muaj cov hluav taws xob zoo heev thiab tuaj yeem tsim qhov chaw tsis muaj hluav taws xob thiab hloov chaw kub thiab txuas ntxiv mus rau qhov hluav taws kub.

Tsis tas li ntawd, cov pa roj carbon monoxide colle colute oleygen nyob rau saum huab cua, ntxiv txo cov txheej txheem ntawm oxygen nrog combustibles, yog li muaj txiaj ntsig zoo tiv thaiv kev sib txuas. Qhov tsim thiab muaj kev ruaj khov ntawm cov roj carbon monoxized no yog tus yuam sij rau MCA tuaj yeem ua lub luag haujlwm ua lub luag haujlwm ua lub ntsej muag retardant.

(3) cov tshuaj tiv thaiv tshuaj ua cov dej vapor

Nyob rau hauv ib puag ncig kub siab tshaj plaws, MCA yuav dhau mus ua cov kev xav tsis zoo thiab tso tawm qee yam ntawm cov dej vapor. Dej vapor tuaj yeem txo cov kub hauv lub zos thiab nqa tawm thaum tshav kub kub los ntawm evaporation, yog li txias qhov cub hluav taws xob. Tsis tas li ntawd, kev tsim cov dej vapor kuj tseem tuaj yeem txo cov pa roj oxygen ib ncig ntawm qhov cub hluav taws, txuas ntxiv tiv thaiv kev sib kis cov nplaim taws.

(4) cov nyhuv synergistic nrog lwm cov khoom sib ntxiv

Ntxiv rau nws tus kheej nplaim taws retardant nyhuv, melamine canalurate tseem tuaj yeem ua ke nrog lwm tus nplaim ci retardants lossis fitters los txhim kho cov nplaim hluav taws xob tag nrho cov khoom siv. Piv txwv li, MCA feem ntau siv nyob rau hauv kev sib xyaw nrog phosphorus nplaim taws, thiab lwm yam ntawm cov khoom siv thiab siv zog ua kom muaj txiaj ntsig ntau dua cov nplaim hluav taws xob.

Qhov zoo thiab cov ntawv thov ntawm Melamine Cyalurate

(1) Ib puag ncig tus phooj ywg thiab tsis muaj tshuaj lom

Piv nrog cov nplaim taws cov nplaim hluav taws xob, MCA tsis tso cov pa roj teeb Halogen, thiab lwm yam) Thaum lub ntsej muag muaj kuab paug rau ib puag ncig kev noj qab haus huv thiab kev ua phem rau tib neeg. Cov txheej txheem nitrogen tso tawm ntawm MCA muaj kev nyab xeeb, yog li nws yog ib puag ncig zoo ib puag ncig thaum siv thiab tsis muaj kev cuam tshuam tsawg ntawm cov ecological ib puag ncig.

(2) Zoo thermal stability thiab huab cua tsis kam

MCA muaj siab thermal stability, tuaj yeem tswj cov tshuaj ruaj khov ntawm cov ntsuas kub ntawm qhov kub, thiab tiv thaiv kev sib txuas ua los ntawm kev kub siab. Hauv qee qhov chaw siab ua haujlwm siab, MCA tuaj yeem muab kev tiv thaiv ntev li cov nplaim taws retardant.

Ib qho ntxiv, MCA tseem muaj huab cua muaj zog tiv thaiv, tuaj yeem ua tau zoo siv sijhawm ntev, thiab hloov kho rau cov kev hloov pauv sib txawv.

(3) Cov pa luam yeeb tsawg

MCA tsim cov pa luam yeeb tsawg dua thaum ua kom sov siab rau qhov kub. Piv nrog cov nplaim taws cov nplaim taws ua ke, nws tuaj yeem txo qhov kev tso tawm cov roj lom hauv hluav taws thiab txo cov pa luam yeeb rau cov neeg ua haujlwm.

 

Raws li ib puag ncig phooj ywg thiab tsis muaj tshuaj lomnplaim taws retardant, Melamine Cyalurate muaj cov nplaim taws sib txawv retardant mechanism uas qhia tau ntau yam kev thov kev cia siab hauv cov ntaub ntawv niaj hnub no. Nrog rau kev txhim kho txuas ntxiv ntawm ib puag ncig kev tiv thaiv ib puag ncig thiab kev nyab xeeb, melamline canalurate yuav siv nyob rau hauv ntau daim teb ntawm cov nplaim taws retardant cov ntaub ntawv.
