1. Nrog kev nce qib ntawm kev siv tshuab, cov khoom siv roj hmab tau siv dav hauv ntau yam kev lag luam.Hlau thiab cable, roj hmab hlua, conveyor siv, roj hmab hose, cua duct, roj hmab siv, thiab roj hmab cov khoom siv nyob rau hauv cov hluav taws xob thiab hluav taws xob kev lag luam yuav tsum ua tau raws li lub teb chaws tus qauv yuav tsum tau nyob rau hauv cov nqe lus ntawm nplaim retardancy thiab txhua yam khoom.Qhov kev thov rau cov nplaim hluav taws kub nyhiab ntawm cov khoom siv roj hmab kuj nce ntxiv, thiab kev txhim kho thiab siv cov nplaim hluav taws kub hnyiab tau dhau los ua qhov tseem ceeb.
Muaj ntau ntau hom roj hmab, thiab qhov kev ua tau zoo ntawm txhua hom roj hmab sib txawv.Cov roj hmab feem ntau muaj qhov ntsuas tsis tshua muaj oxygen thiab qhov kub ntawm qhov decomposition tsawg, ua rau nws yooj yim rau hlawv.Yog li ntawd, kawm txog cov yam ntxwv ntawm combustion ntawm roj hmab, ntxiv nplaim retardants los yog kev txhim kho cov combustion kev ua tau zoo ntawm roj hmab nws tus kheej tau dhau los ua txoj hauv kev tseem ceeb los npaj cov nplaim hluav taws.
2. Ntau txoj hauv kev tseem ceeb ntawm cov roj hmab nplaim hluav taws
Txoj hauv kev tseem ceeb ntawm cov nplaim hluav taws xob yog kom txo qis thermal decomposition thiab thaiv cov txheej txheem combustion.Cov txheej txheem tshwj xeeb ntawm nplaim taws retardancy yog raws li nram no:
1) Ntxiv ib lossis ntau yam khoom los hloov cov thermal decomposition tus cwj pwm ntawm roj hmab, ua kom lub thermal decomposition kub ntawm cov roj hmab npaj, thiab txo cov roj combustible generated thaum decomposition.
2) Cov khoom siv ntxiv tuaj yeem tsim cov roj uas tsis muaj hluav taws xob lossis cov khoom hnyav uas cais O2 thaum ua kom sov, lossis tuaj yeem nqus tau cov cua sov thaum cua sov, ua rau nws tsis tuaj yeem ua tau raws li peb qhov combustion yam (combustible, oxygen, thiab ncav cuag lub ignition point).
3) Ntxiv cov tshuaj uas tuaj yeem ntes HO ·, cuam tshuam cov tshuaj tiv thaiv kab mob, thiab tshem tawm cov nplaim hluav taws.
4) Hloov cov qauv lossis cov khoom ntawm cov roj hmab molecular chains, txhim kho lawv cov thermal decomposition muaj peev xwm, los yog ua rau lawv nplaim taws.
Vim muaj kev sib raug zoo ntawm cov roj hmab thiab ntau yam khoom siv ntxiv, qhov sib ntxiv ntawm ntau cov nplaim hluav taws kub hnyiab tseem yog ib qho tseem ceeb ntawm cov nplaim hluav taws kub hloov pauv ntawm cov roj hmab tam sim no.
