Kev tiv thaiv kev tiv thaiv: Cree cort chaw ua haujlwm thiab muaj kev nyab xeeb. Cov neeg ua haujlwm yuav tsum yauv kawm tshwj xeeb thiab ua raws li kev ua haujlwm ua haujlwm. Cov neeg ua haujlwm tau nquahu kom hnav cov ntsej muag lim heel Tseg deb ntawm hluav taws thiab cov khoom cua sov. Kev haus luam yeeb yog nruj me ntsis txwv nyob rau hauv chaw ua haujlwm. Cov neeg ua haujlwm yuav tsum siv tawg-pov thawj kev ua pa pa tshuab thiab khoom siv. Tiv thaiv vapor los ntawm kev xau mus rau saum huab cua hauv qhov chaw ua haujlwm. Zam kev sib cuag nrog oxidants, acids, thiab alkalis.

Cia Kev Tiv Thaiv: Feem ntau, cov khoom yog ntxiv rau inhibitors. Khaws nws rau hauv qhov chaw txias, zoo-ventilated tsev rau khoom. Tseg deb ntawm hluav taws thiab cov khoom cua sov. Nws yuav tsum tau muab khaws cia cais los ntawm oxidants, acids, thiab alkalis; Tsis txhob sib xyaw lawv. Siv tawg-pov thawj teeb pom kev zoo thiab cov chaw tua hluav taws xob. Txwv tsis pub siv cov cuab yeej siv cov khoom siv thiab cov cuab yeej uas muaj feem ntau los tsim cov txim taws. Cov chaw cia khoom yuav tsum tau nruab nrog cov khoom siv hluav taws xob muaj xwm ceev thiab cov khoom siv muaj peev xwm.

Kev siv

Hauv polymer synthesis: Raws li ib qho tseem ceeb cov khoom siv, diethylene glycoling aschol ether tuaj yeem koom nrog dawb - radical thiab cationic polymerization kev tawm tsam. Nws tuaj yeem copolymerize nrog cov monomers muaj ob chav khi, qhia cov ntaub pua tes ua kom yooj yim, dej - tsis kam, thiab solubility ntawm polymers. Nws yog qhov dav nyob rau hauv kev tsim cov txheej txheej thiab cov nplaum. Nyob rau hauv cov tsho me, nws tuaj yeem txhim kho cov nplaum thiab huab cua - kev tiv taus; Hauv cov nplaum, nws tuaj yeem txhim kho cov viscosity thiab yooj.

Hauv Cov Khoom Siv Tshuaj Ntau Lawm: Diethylene glycoling wherinyl ether ua lub luag hauj lwm tseem ceeb hauv cov mercury - dawb lis kev ntawm acetaldehyde. Piv nrog cov mercury - raws li txoj kev, cov mercury muaj cov kev zoo sib txawv raws li nws tuaj yeem txo cov kuab paug muaj kuab lom. Tus acetaldehyde tsim yog ib qho tseem ceeb mis feedstock. Nws yog siv los synthesize acetic acid, yas tom kawg tuaj yeem siv los tsim polyvinyl acetection emulsion, thiab lwm yam, cov nplaum, thiab lwm yam khoom lag luam.
