Feem ntau siv ua cov khoom siv raw rau vinyl chloride, ethylene glycol, oxalic acid, ethylenediamine, tetraethyl lead, polyethylene polyamine, thiab benzil. Kuj siv ua cov kuab tshuaj rau cov roj, cov resins, thiab roj hmab; ua cov tshuaj ntxuav qhuav; ua cov tshuaj rho tawm rau cov tshuaj tua kab xws li pyrethrin, caffeine, cov vitamins, thiab cov tshuaj hormones; ua cov tshuaj ntub dej, cov tshuaj nkag mus, cov tshuaj dewaxing roj av, thiab cov tshuaj tiv thaiv kev sib tsoo. Tsis tas li ntawd, nws siv rau hauv kev tsim cov tshuaj tua kab thiab ua cov khoom siv raw rau cov tshuaj xws li nematocide thiab piperazine. Hauv kev ua liaj ua teb, nws tuaj yeem siv ua cov tshuaj fumigant rau cov nplej thiab cov nplej, nrog rau cov tshuaj tua kab hauv av.
Siv rau kev tshuaj xyuas boron thiab ua cov tshuaj rho tawm rau cov roj thiab luam yeeb. Kuj tseem siv rau hauv kev tsim cov acetyl cellulose.
Siv ua ib qho tshuaj reagent analytical, xws li cov kuab tshuaj thiab cov khoom txheem rau kev tshuaj ntsuam chromatographic. Kuj siv ua cov extractant rau cov roj thiab hauv cov organic synthesis.
Siv ua tus neeg ntxuav, tshuaj rho tawm, tshuaj tua kab, thiab tshuaj ntxuav hlau.
Siv ua cov kuab tshuaj rau cov quav ciab, cov rog, roj hmab, thiab lwm yam, thiab ua cov tshuaj tua kab rau cov noob.
Cov Khoom Phom Sij ntawm Dichloroethane:
Nws cov pa ua ib qho sib xyaw nrog huab cua, uas tuaj yeem hlawv thiab ua rau muaj kev kub hnyiab lossis tawg thaum raug hluav taws qhib lossis kub heev. Nws reacts heev nrog cov neeg sawv cev oxidizing. Thaum raug cua sov heev, nws decomposes los tsim cov pa lom thiab corrosive. Nws cov pa hnyav dua li huab cua thiab tuaj yeem kis mus rau thaj chaw deb ntawm qib qis dua, hlawv thiab hlawv rov qab thaum raug hluav taws. Yog tias raug cua sov heev, lub siab hauv lub thawv yuav nce ntxiv, ua rau muaj kev pheej hmoo ntawm kev tawg lossis tawg. Nws corrodes cov yas thiab roj hmab.
Kev Kub Hnyiab (Liab): 3 Kev Ua Haujlwm (Daj): 0
Cov Khoom Siv Hluav Taws Xob (Kev lwj): Carbon monoxide, carbon dioxide, hydrogen chloride, phosgene.
Kev Ruaj Ntseg: Ruaj khov
Cov Khoom Siv Tsis Sib Xws: Cov neeg sawv cev oxidizing muaj zog, cov kua qaub, cov alkalis.
Kev Phom Sij Polymerization: Tsis siv tau
Cov Txuj Ci Tua Hluav Taws: Ua npuas dej, hmoov qhuav, carbon dioxide, xuab zeb, lossis dej tsuag. Yog tias cov tshuaj lossis cov kua dej uas muaj kuab paug nkag mus rau hauv dej, qhia rau cov neeg siv dej hauv qab dej txog kev ua qias tuaj yeem ua rau muaj kuab paug, nrog rau cov neeg saib xyuas kev noj qab haus huv hauv zos, cov tub ceev xwm tua hluav taws, thiab cov chaw tswj kev ua qias tuaj.
Kev Tswj Xyuas Qhov Xaus:
Tshem cov neeg ua haujlwm tawm ntawm thaj chaw muaj kuab paug mus rau thaj chaw nyab xeeb, thiab txwv tsis pub cov neeg ua haujlwm tsis raug cai nkag mus rau hauv thaj chaw muaj kuab paug. Txiav cov khoom siv hluav taws xob. Cov neeg teb thaum muaj xwm txheej ceev yuav tsum hnav cov khoom siv tiv thaiv. Kaw qhov xau yog tias ua tau kom muaj kev nyab xeeb. Kev txau dej tuaj yeem txo qhov evaporation tab sis yuav tsis txo qhov kev kub hnyiab ntawm cov khoom xau hauv qhov chaw kaw. Nqus nrog xuab zeb, vermiculite, lossis lwm yam khoom siv inert, tom qab ntawd sau thiab thauj mus rau qhov chaw pov tseg rau kev kho. Los yog, txhuam nrog cov emulsion ua los ntawm cov dispersants uas tsis kub hnyiab. Cov dej ntxuav diluted yuav tsum tau tso tawm mus rau hauv lub tshuab dej khib nyiab tom qab kho kom ua tau raws li cov qauv pa phem. Yog tias muaj qhov xau loj, siv cov pas dej kom khaws cov khoom, tom qab ntawd rov qab, hloov, thiab rov ua dua tshiab. Qhov chaw muaj kuab paug yuav tsum tau kho kom tsis muaj teeb meem.
