Lub hom phiaj Editing tshaj tawm
Styrene feem ntau yog siv los ua monomer tseem ceeb hauv cov khoom siv hluavtaws, ion txauv resins, thiab cov roj hmab hluavtaws, nrog rau hauv kev lag luam xws li tshuaj, tshuaj zawv plaub hau, tshuaj tua kab, thiab kev ua ntxhia.
Kev ntsuas kub ceev kho thiab tshaj tawm
Kev sib cuag ntawm daim tawv nqaij: Tshem tawm cov khaub ncaws tsis huv thiab yaug daim tawv nqaij nrog xab npum thiab dej.
Kev sib cuag ntawm qhov muag: Tam sim ntawd rub daim tawv muag thiab yaug kom huv si nrog cov dej ntws loj los yog cov kua qaub physiological tsawg kawg 15 feeb.Nrhiav kev kho mob.
Inhalation: Tshem tawm sai sai ntawm qhov chaw mus rau qhov chaw uas muaj huab cua ntshiab.Tuav txoj kev ua pa uas tsis muaj kev cuam tshuam.Yog tias ua pa nyuaj, muab cov pa oxygen.Yog tias ua tsis taus pa, tam sim ntawd ua pa ua pa.Nrhiav kev kho mob.
Noj: Haus dej sov kom ntau kom ntuav.Nrhiav kev kho mob.
Hloov kho thiab tshaj tawm cov kev tiv thaiv hluav taws
Cov yam ntxwv muaj kev phom sij: Nws cov vapor thiab huab cua tuaj yeem tsim cov khoom tawg, uas ua rau muaj kev pheej hmoo ntawm kev sib tsoo thiab tawg hauv kev sib cuag nrog cov nplaim taws qhib, kub kub, lossis oxidants.Thaum ntsib cov acidic catalysts xws li Lewis catalysts, Ziegler catalysts, sulfuric acid, hlau chloride, aluminium chloride, thiab lwm yam, lawv tuaj yeem tsim ua phem polymerization thiab tso tawm ntau cov cua sov.Nws cov vapor hnyav dua li huab cua thiab tuaj yeem sib kis mus rau qhov deb ntawm cov ntsiab lus qis.Nws yuav ignite thiab ignite thaum ntsib qhov hluav taws kub.
Cov khoom tsim kev puas tsuaj: carbon monoxide, carbon dioxide.
Txoj kev tua hluav taws: Tshem lub thawv los ntawm qhov chaw tua hluav taws mus rau qhov chaw qhib kom ntau li ntau tau.Txau dej kom lub thawv hluav taws kub kom txog thaum hluav taws tua.Extinguishing agent: ua npuas ncauj, qhuav hmoov, carbon dioxide, xuab zeb.Kev tua hluav taws nrog dej tsis zoo.Thaum muaj hluav taws kub, cov neeg tua hluav taws yuav tsum ua haujlwm hauv qhov chaw tiv thaiv.
