Methylene chloride, uas yog ib qho organic compound.

Cov Khoom:Ntshiabmethylene chloridetsis muaj qhov flash point. Cov kuab tshuaj uas muaj cov dichloromethane thiab roj av sib npaug, cov kuab tshuaj naphtha lossis toluene tsis yooj yim hlawv. Txawm li cas los xij, thaum dichloromethane sib xyaw nrog acetone lossis methyl cawv kua hauv 10: 1 piv sib xyaw, qhov sib tov muaj qhov flash point, pa thiab cua los ua cov khoom sib xyaw tawg, qhov txwv tawg yog 6.2% ~ 15.0% (ntim).

DAIM NTAWV THOV:

1. Siv rau kev fumigation nplej thiab tub yees ntawm lub tub yees qis thiab cua txias.

2, Siv ua cov kuab tshuaj, tshuaj rho tawm, tus neeg sawv cev mutagenic.

3, Siv rau hauv kev lag luam hluav taws xob. Feem ntau siv los ua tus neeg sawv cev ntxuav kom tshem tawm cov roj.

4, Siv ua tshuaj loog hauv zos, tshuaj txias, tshuaj tua hluav taws, tshuaj ntxuav thiab ntxuav cov hlau nto.

5, Siv ua ib qho nruab nrab hauv cov organic synthesis.

Txoj kev npaj:

1. Cov txheej txheem chlorination roj av Cov roj av ua rau cov pa chlorine sib xyaw nrog cov pa chlorine. Tom qab hydrochloric acid uas tsim los ntawm hydrogen chloride raug nqus los ntawm dej, cov hydrogen chloride seem seem raug tshem tawm nrog lye, thiab cov khoom tiav lawm tau los ntawm kev ziab, nias, condensation thiab distillation.

2. Chloromethane thiab chloromethane tau ua ke nrog cov pa roj chlorine hauv qab lub teeb 4000kW los tsim dichloromethane, uas tau ua tiav los ntawm kev ntxuav alkali, nias, ua kom noo, ziab thiab kho. Cov khoom tseem ceeb yog trichloromethane.

Kev Ruaj Ntseg:

1.Cov kev ceev faj rau kev ua haujlwm:Tsis txhob cia muaj pos huab thaum lub sijhawm ua haujlwm, thiab hnav cov khoom siv tiv thaiv tus kheej kom zoo. Tsis txhob tso cov pa thiab cov pos huab rau hauv huab cua ntawm thaj chaw ua haujlwm. Ua haujlwm hauv ib cheeb tsam tshwj xeeb uas muaj cua nkag tau zoo thiab siv tsawg kawg nkaus. Cov khoom siv teb rau thaum muaj xwm txheej ceev yuav tsum muaj txhua lub sijhawm los tua hluav taws thiab daws cov dej nchuav. Cov thawv cia khoom khoob tseem yuav muaj cov khoom seem txaus ntshai. Tsis txhob ua haujlwm ze ntawm kev vuam, nplaim taws, lossis cov chaw kub.

2.Kev ceev faj txog kev khaws cia:Khaws cia rau qhov chaw txias, qhuav, thiab muaj cua nkag tau zoo uas tsis muaj hnub ci ncaj qha. Khaws cia kom deb ntawm qhov chaw kub, nplaim taws thiab cov khoom tsis sib xws xws li cov tshuaj oxidant muaj zog, cov kua qaub muaj zog thiab cov kua qaub nitric. Khaws cia rau hauv lub thawv uas muaj daim ntawv lo zoo. Cov thawv tsis siv thiab cov thoob khoob yuav tsum tau npog kom nruj. Tsis txhob ua rau lub thawv puas thiab tshuaj xyuas lub tank tsis tu ncua rau qhov tsis zoo xws li tawg lossis nchuav. Cov thawv tau muab cov roj galvanized lossis Phenolic resin los txo qhov ua tau ntawm kev lwj ntawm methylene chloride. Kev khaws cia tsawg. Muab cov cim ceeb toom tso rau qhov twg tsim nyog. Qhov chaw khaws cia yuav tsum tau cais tawm ntawm thaj chaw ua haujlwm uas muaj neeg ua haujlwm ntau thiab txwv tsis pub nkag mus rau thaj chaw ntawd. Siv cov yeeb nkab yas uas tau tsim los siv nrog cov tshuaj kom tso cov tshuaj lom tawm. Cov khoom siv no tuaj yeem tsim hluav taws xob static uas tuaj yeem ua rau kub hnyiab. Khaws cia rau hauv qhov chaw txias, qhuav, thiab muaj cua nkag tau zoo uas tsis muaj hnub ci ncaj qha.

3.Ntim thiab kev thauj mus los:Siv cov thoob hlau galvanized kom kaw, 250kg ib thoob, tsheb ciav hlau thauj roj, tsheb thauj khoom tuaj yeem thauj mus los. Nws yuav tsum khaws cia rau hauv qhov chaw txias, tsaus ntuj, qhuav, thiab muaj cua nkag zoo, xyuam xim rau cov dej noo.
