Methylene chloride, cov organic compound nrog cov tshuaj ch2cl2, yog cov kua tsis muaj kob nrog cov ntxhiab tsw ntxhiab tsw zoo sib xws rau ether. Nws yog me ntsis soluble hauv dej, ethanol thiab ether. Nyob rau hauv ib txwm muaj mob, nws yog ib qho tsis-sib xyaw ua ke nrog cov taw tes npau npau tsawg. Thaum nws vapor ua lub siab huab cua, nws yuav tsim kom muaj zog kub hnyiab, uas yog siv tau los hloov cov roj av roj av ci, ether, etc.
Khoom:HuvMethylene chloridetsis muaj flash taw tes. Cov kuab tshuaj uas muaj sib npaug ntawm dichhloromime thiab roj av, hnyav naphtha lossis toluene tsis yog taws. Txawm li cas los xij, thaum dichhloromethane tau sib xyaw nrog cov dej cawv lossis metyl thiab cua sib xyaw ua ke, tawg kom tsawg 6.2% ~ 15.0% (ntim).
Daim ntawv thov:
1. Siv rau cov nplej fumigation thiab tub yees ntawm cov tub yees qeeb thiab cov cua txias chav tsev.
2, siv raws li cov kuab tshuaj, extractant, mutagenic tus neeg sawv cev.
3, siv hauv kev lag luam hluav taws xob. Feem ntau siv los ua tus neeg sawv cev tu kom tshem tawm cov roj.
4, siv los ua kev tshuaj ntsuab hauv plawv, tub yees, tua hluav taws, cov txheej txheem hlau ua kom huv thiab ua rau tus neeg sawv cev.
5, Siv los ua nruab nrab hauv cov khoom siv hauv nruab nrog cev.
Kev npaj txoj kev:
1. Natural Gas Pab cov txheej txheem ntuj uas muaj roj cua sov nrog cov tshuaj cholorine. Tom qab hydrochloric acid tsim los ntawm hydrogen chloride yog nqus dej, thiab cov khoom tiav yog tau txais los ntawm kev ziab, nias, ua kom lwg thiab cov hws thiab distillation.
2. Chloromethane thiab chloromethane muaj kev cuam tshuam nrog tshuaj chlorine roj hauv 4000KW teeb, uas tau ua tiav los ntawm Alkali ntxuav, Compression, Kev ua kom tawg, kom qhuav, kom qhuav thiab kho kom qhuav. Lub ntsiab ntawm kev cuam tshuam yog trichloromomethane.
Kev Ruaj Ntseg:
1.Ceev faj rau kev ua haujlwm:Zam cov tee teeb thaum lub sijhawm ua haujlwm, thiab hnav cov khoom tiv thaiv tus kheej. Zam kev tso tawm ncu thiab cov huab ntws mus rau ntawm cov pa ntawm thaj chaw ua haujlwm. Kev khiav lag luam hauv ib thaj chaw tshwj xeeb nrog cua zoo thiab muaj pes tsawg tus nqi. Cov lus teb thaum muaj xwm ceev yuav tsum muaj nyob rau txhua lub sijhawm los tua hluav taws thiab cuam tshuam nrog nchuav. Tawg cia cov khoom ntim yuav tseem muaj cov seem seem muaj kev phom sij. Tsis txhob ua haujlwm nyob ze vuam, nplaim taws, lossis cov kub.
2.Cia Kev ceev faj:Khaws rau hauv qhov chaw txias, qhuav, zoo-ventilated qhov chaw tsis muaj kev tshav ntuj ncaj qha. Khaws kom deb ntawm qhov cua sov, nplaim taws thiab inclatibilities xws li oxidant muaj zog, muaj zog acid thiab nitric acid. Khaws rau hauv cov thawv ntim khoom kom zoo. Cov ntim tsis siv thiab cov nruas khoob yuav tsum tau npog kom nruj. Zam kev puas tsuaj rau lub thawv thiab tshuaj xyuas lub tank tsis tu ncua rau qhov tsis xws luag xws li tawg lossis tawg. Cov ntim yog lined nrog galvanized lossis phenolic resin los txo qhov tau txais kev txiav txim siab ntawm methylene chloride. Txwv tsis pub cia. Tshaj tawm cov cim ceeb toom uas tsim nyog. Thaj chaw cia yuav tsum tau sib cais los ntawm cov neeg ua haujlwm ua haujlwm thaj chaw ua haujlwm thiab kev txwv tsis pub nkag mus rau thaj chaw. Siv cov kav dej yas uas tau tsim rau kev siv nrog cov tshuaj mus rau cov tshuaj muaj tshuaj lom. Cov khoom tuaj yeem tsim hluav taws xob zoo li qub uas tuaj yeem ua rau muaj kev sib txuas. Khaws rau hauv qhov chaw txias, qhuav, zoo ventilated qhov chaw deb ntawm tshav ntuj ncaj qha.
3.Ntim thiab Tsheb Thauj Mus Los:Siv Galvanized Hlau Barrels kom raug kaw, 250kg ib lub thoob, tsheb ciav hlau tank, tsheb tuaj yeem thauj khoom. Nws yuav tsum tau muab cia rau hauv qhov txias, tsaus, qhuav, qhov chaw muaj ventilated, xyuam xim rau ya raws.
