Dimethyl CarbonateKev siv:
1. Ib qho tshiab uas tsis muaj tshuaj lom hnyav tuaj yeem hloov tau cov toluene, xylene, ethyl acetate, butyl acetate, acetone los yog butanone hauv cov xim thiab cov nplaum.Nws yog ib puag ncig tus phooj ywg ntsuab tshuaj lom neeg cov khoom
2. Tus neeg saib xyuas zoo methylating, tus neeg saib xyuas carbonylating, tus neeg sawv cev hydroxymethylating thiab methoxylating tus neeg sawv cev yog siv cov khoom siv tshuaj raw khoom.
3. Phosgene, dimethyl sulfate, methyl chloroformate thiab lwm yam tshuaj lom neeg raug txiav txim siab hloov
4. Synthesis ntawm polycarbonate, diphenyl carbonate, isocyanate, thiab lwm yam
5. Hauv cov tshuaj, nws yog siv los tsim cov tshuaj tiv thaiv kab mob, tshuaj tua kab mob thiab tshuaj tua kab mob, cov vitamins thiab cov tshuaj hauv nruab nrab paj hlwb.
6. Cov tshuaj tua kab feem ntau yog siv los tsim methyl isocyanate, thiab tom qab ntawd qee cov tshuaj carbamate thiab tshuaj tua kab (anisole)
7. Gasoline additives, lithium roj teeb electrolyte, thiab lwm yam

UN: 1161 Chav Kawm: 3 PG: Ⅱ
HS Code: 2920900090
Cov yam ntxwv txaus ntshai
Flammable, flammable thaum qhib hluav taws thiab kub kub.Hauv qhov xwm txheej hluav taws kub, cov thawv ntim khoom kub muaj kev pheej hmoo tawg.
Cov khoom tsim kev puas tsuaj
Cov pa roj carbon monoxide, carbon dioxide.
Txoj kev tua hluav taws
Xuab zeb.Ua npuas ncauj, hmoov qhuav, carbon dioxide.
Kev kho mob xwm txheej ceev
Tshem tawm cov neeg ua haujlwm los ntawm qhov chaw paug paug mus rau thaj chaw nyab xeeb sai sai, cais lawv thiab nruj me ntsis txwv tsis pub nkag mus.Txiav tawm qhov hluav taws kub.Nws raug pom zoo tias cov neeg ua haujlwm kho mob thaum muaj xwm txheej ceev hnav tus kheej muaj lub siab ua pa thiab cov khaub ncaws ua haujlwm tiv thaiv zoo li qub.Tsis txhob kov cov xau ncaj qha.Txiav tawm lub hauv paus ntawm kev xau kom deb li deb tau.Tiv thaiv kom tsis txhob ntws mus rau hauv qhov chaw txwv xws li cov kav dej phwj tuaj thiab cov kwj dej tawm.Me me: nqus nrog xuab zeb, vermiculite lossis lwm yam khoom siv inert.Sau thiab thauj mus rau qhov chaw qhib rau faus, evaporation lossis incineration.Cov dej xau loj heev: tsim lub dike lossis khawb lub qhov rau sau.Npog nrog ua npuas ncauj kom txo tau cov pa phem.Hloov mus rau lub tsheb tank lossis cov khoom tshwj xeeb nrog lub twj tso kua mis tawg, rov ua dua lossis thauj mus rau qhov chaw kho mob pov tseg.
Kev ceev faj rau kev ua haujlwm
Kev ua haujlwm airtight thiab txhim kho qhov cua.Cov neeg ua haujlwm yuav tsum tau txais kev cob qhia tshwj xeeb thiab ua raws li cov txheej txheem ua haujlwm.Nws raug nquahu kom cov neeg ua haujlwm hnav lub qhov ncauj qhov ntswg rau lub qhov ncauj qhov ncauj (ib nrab qhov ncauj qhov ntswg), tshuaj tiv thaiv tsom iav, hnav khaub ncaws ua haujlwm zoo li qub thiab cov hnab looj tes roj hmab.Khaws kom deb ntawm qhov hluav taws kub thiab cua sov.Kev haus luam yeeb yog txwv tsis pub nyob hauv chaw ua haujlwm.Siv cov khoom tawg-pov thawj qhov cua thiab cov khoom siv.Tiv thaiv kom tsis txhob muaj pa tawm mus rau hauv huab cua ntawm qhov chaw ua haujlwm.Tsis txhob sib cuag nrog oxidants, reductants thiab acids.Ua tib zoo saib xyuas kom tsis txhob muaj kev puas tsuaj rau lub pob thiab lub thawv.Cov khoom siv tua hluav taws thiab cov khoom siv kho mob thaum muaj xwm ceev ntawm cov khoom sib xws thiab ntau yuav tsum tau muab.Cov thawv ntim khoom pov tseg yuav muaj cov khoom tsis zoo.
Kev ceev faj cia
Khaws rau hauv ib qho chaw txias, qhuav thiab zoo ventilated uas tsis yog combustible warehouse.Khaws kom deb ntawm qhov hluav taws kub thiab qhov cua sov.Qhov kub cia yuav tsum tsis pub tshaj 10 ℃.Khaws cov ntim ntim kaw.Nws yuav tsum tau muab cais tawm ntawm oxidants, reductants, acids, thiab lwm yam. thiab tsis pub sib xyaw cia.Kev tawg pov thawj teeb pom kev zoo thiab qhov cua qhov chaw yuav tsum tau txais yuav.Nws yog txwv tsis pub siv cov cuab yeej siv tshuab thiab cov cuab yeej uas yooj yim los tsim cov txim taws.Lub chaw cia khoom yuav tsum tau nruab nrog cov khoom siv kho mob thaum muaj xwm txheej ceev thiab cov khoom siv tau txais tsim nyog.
Hebei Guanlang Biotechnology Co., Ltd. belongs rau Guanlang Group, uas tau tsim nyob rau hauv 2007, nyob rau hauv Shijiazhuang nroog uas yog lub peev ntawm Hebei xeev thiab hub sector ntawm Beijing Tianjin thiab Hebei thiab muaj kom zoo dua ntawm kev thauj mus los yooj yim.Peb lub tuam txhab yog niaj hnub high-tech chemical enterprise nrog Kev Tshawb Fawb & Kev Tsim Kho, ntau lawm thiab muag.Peb muaj peb tus kheej lub Hoobkas thiab chaw kuaj mob, kuj muab kev pabcuam customized synthesis rau peb cov neeg siv khoom.
