I-Methylene chloride, inhlanganisela yezinto eziphilayo enefomula yamakhemikhali i-CH2Cl2, iwuketshezi olungabonakali olungenambala olunephunga elibi elifana ne-ether. Incibilika kancane emanzini, i-ethanol kanye ne-ether. Ngaphansi kwezimo ezijwayelekile, iyisinyibilikisi esingashisi esinendawo yokubilisa ephansi. Lapho umhwamuko wayo uba phezulu emoyeni oshisayo, uzokhiqiza igesi exubile evuthayo kancane, evame ukusetshenziselwa ukufaka esikhundleni se-ether evuthayo, i-ether, njll.
Izakhiwo:Okumsulwai-methylene chlorideayinayo i-flash point. Izinyibilikisi eziqukethe amavolumu alinganayo e-dichloromethane kanye nophethiloli, i-solvent naphtha noma i-toluene azishisi. Kodwa-ke, uma i-dichloromethane ixutshwa ne-acetone noma i-methyl Chemicalbook alcohol liquid ekuxubeni kwesilinganiso esingu-10: 1, ingxube ine-flash point, umhwamuko nomoya ukwakha ingxube eqhumayo, umkhawulo wokuqhuma ungu-6.2% ~ 15.0% (ivolumu).
ISICELO:
1. Isetshenziselwa ukuhlanza okusanhlamvu kanye nokugcina esiqandisini sefriji kanye neyunithi yokupholisa umoya enomfutho ophansi.
2, Isetshenziswa njenge-solvent, extractant, kanye ne-mutagenic agent.
3, Isetshenziswa embonini ye-elekthronikhi. Ivame ukusetshenziswa njenge-ejenti yokuhlanza ukususa uwoyela.
4, Isetshenziswa njenge-anesthetic yendawo yamazinyo, i-refrigerant, i-ejenti yokucima umlilo, i-ejenti yokuhlanza nokususa amafutha ebusweni bensimbi.
5, Isetshenziswa njenge-intermediate ekuhlanganisweni kwezinto eziphilayo.
Indlela yokulungiselela:
1. Inqubo yokufaka i-chlorine kugesi yemvelo Igesi yemvelo isabela kugesi we-chlorine. Ngemva kokuba i-hydrochloric acid ekhiqizwa yi-hydrogen chloride imuncwa ngamanzi, i-hydrogen chloride eseleyo isuswa nge-lye, bese umkhiqizo oqediwe utholakala ngokuwomisa, ukucindezela, ukujiya kanye nokuhluzwa.
2. I-Chloromethane kanye ne-chloromethane zasabela ngegesi ye-chlorine ngaphansi kokukhanya okungu-4000kW ukuze kukhiqizwe i-dichloromethane, eyaqedwa ngokuwasha nge-alkali, ukucindezela, ukujiya, ukomisa kanye nokulungisa. Umkhiqizo oyinhloko olandelanayo yi-trichloromethane.
Ukuphepha:
1.Izinyathelo Zokuqapha Zokusebenza:Gwema ukuvuza kwenkungu ngesikhathi sokusebenza, futhi gqoka imishini yokuzivikela efanele. Gwema ukukhipha umusi kanye namaconsi enkungu emoyeni wendawo yokusebenza. Sebenza endaweni ethile enomoya omuhle futhi uthathe inani elincane. Imishini yokusabela eziphuthumayo kufanele itholakale ngaso sonke isikhathi ukuze ilwe nemililo futhi ibhekane nokuchitheka. Izitsha zokugcina ezingenalutho zingase zibe nezinsalela eziyingozi. Ungasebenzi eduze kwezindawo zokushisela, ilangabi, noma izindawo ezishisayo.
2.Izinyathelo zokuphepha zokugcina:Gcina endaweni epholile, eyomile, enomoya omuhle ngaphandle kokukhanya kwelanga okuqondile. Gcina kude nomthombo wokushisa, ilangabi kanye nokungahambisani njenge-oxidant enamandla, i-asidi enamandla kanye ne-nitric acid. Gcina esitsheni esinelebula efanele. Izitsha ezingasetshenziswa kanye nama-drum angenalutho kufanele zimbozwe kahle. Gwema umonakalo esitsheni futhi uhlole njalo amaphutha afana nokuphuka noma ukuchitheka. Izitsha zimbozwe nge-galvanized noma i-Phenolic resin ukunciphisa amathuba okubola kwe-methylene chloride. Isitoreji esilinganiselwe. Beka izimpawu zesexwayiso lapho kufaneleka khona. Indawo yokugcina kufanele ihlukaniswe nendawo yokusebenza ebanzi yabasebenzi kanye nokufinyelela okulinganiselwe endaweni. Sebenzisa amapayipi epulasitiki aklanyelwe ukusetshenziswa nezinto ukukhipha izinto ezinobuthi. Izinto zingakha ugesi ongashintshi ongabangela ukusha. Gcina endaweni epholile, eyomile, enomoya omuhle kude nokukhanya kwelanga okuqondile.
3.Ukupakisha kanye nokuthuthwa:Sebenzisa imiphongolo yensimbi egayiwe ukuze ivalwe, 250kg ngebharele, ithangi lesitimela, imoto ingathuthwa. Kufanele igcinwe endaweni ebandayo, emnyama, eyomile, enomoya omuhle, qaphela umswakama.
