I-Methylene chloride, i-organic compound enefomyula yeekhemikhali i-CH2Cl2, lulwelo olungenambala olucacileyo olunevumba elibi elifana ne-ether. Lunyibilika kancinci emanzini, kwi-ethanol nakwi-ether. Phantsi kweemeko eziqhelekileyo, sisinyibilikisi esingatshiyo esinendawo yokubila ephantsi. Xa umphunga waso uba ngumxube ophezulu emoyeni oshushu kakhulu, uya kuvelisa igesi exutyiweyo etsha kancinci, esetyenziswa rhoqo endaweni ye-petroleum ether etshayo, i-ether, njl.
Iipropati:Icocekilei-methylene chlorideayinayo i-flash point. Izinyibilikisi ezineevolumu ezilinganayo ze-dichloromethane kunye nepetroli, i-solvent naphtha okanye i-toluene azitshi. Nangona kunjalo, xa i-dichloromethane ixutywe ne-acetone okanye i-methyl Chemicalbook alcohol liquid kwi-10: 1 ratio mixing, umxube une-flash point, umphunga kunye nomoya ukwenza umxube oqhumayo, umda wokuqhuma yi-6.2% ~ 15.0% (umthamo).
ISICELO:
1. Isetyenziselwa ukufutha iinkozo kunye nokufrijisa ifriji kunye neyunithi yomoya opholileyo enoxinzelelo oluphantsi.
2, Isetyenziswa njengesinyibilikisi, isithambisi, iarhente yokuguqula izinto.
3, Isetyenziswa kwishishini le-elektroniki. Isetyenziswa kakhulu njengesixhobo sokucoca ukususa ioyile.
4, Isetyenziswa njenge-anesthetic yendawo yamazinyo, i-refrigerant, i-arhente yokucima umlilo, i-arhente yokucoca kunye ne-arhente yokususa amafutha kumphezulu wesinyithi.
5, Isetyenziswa njengesixhobo esiphakathi kwi-organic synthesis.
Indlela yokulungiselela:
1. Inkqubo yokukhupha i-chlorine kwigesi yendalo Igesi yendalo isabela kwi-chlorine gas. Emva kokuba i-hydrochloric acid eveliswa yi-hydrogen chloride ifunxwe ngamanzi, i-hydrogen chloride eseleyo isuswa nge-lye, kwaye imveliso egqityiweyo ifunyanwa ngokumisa, ukucinezela, ukufunxa kunye nokucola.
2. I-chloromethane kunye ne-chloromethane zadibana negesi ye-chlorine phantsi kokukhanya kwe-4000kW ukuze kuveliswe i-dichloromethane, eyagqitywa ngokuhlanjwa nge-alkali, ukucinezelwa, ukufuma, ukomiswa kunye nokulungiswa. Imveliso eyintloko yi-trichloromethane.
Ukhuseleko:
1.Amanyathelo okhuseleko xa usebenza:Ziphephe iinkungu eziphumayo ngexesha lokusebenza, kwaye unxibe izixhobo zokuzikhusela ezifanelekileyo. Ziphephe ukukhupha umphunga kunye namaconsi enkungu emoyeni wendawo yokusebenza. Zisebenzele kwindawo ethile enomoya ofanelekileyo kwaye uthathe ubuncinci bomthamo. Izixhobo zokuphendula ngexesha likaxakeka kufuneka zifumaneke ngamaxesha onke ukulwa nomlilo kunye nokujongana nokuchitheka. Izikhongozeli zokugcina ezingenanto zisenokuba neentsalela eziyingozi. Musa ukusebenza kufutshane nendawo yokutshiza, ilangatye, okanye iindawo ezishushu.
2.Amanyathelo okukhusela ukugcina:Gcina kwindawo epholileyo, eyomileyo, enomoya ococekileyo engenalanga ngqo. Gcina kude nomthombo wobushushu, ilangatye kunye nokungahambisani okufana ne-oxidant enamandla, i-asidi enamandla kunye ne-nitric acid. Gcina kwisikhongozeli esineleyibhile efanelekileyo. Izikhongozeli ezingasetyenziswayo kunye needrama ezingenanto kufuneka zigqunywe ngokuqinileyo. Kuphephe ukonakala kwisikhongozeli kwaye uhlole itanki rhoqo ukuze ubone iziphene ezinje ngokuqhekeka okanye ukuchitheka. Izikhongozeli zigqunywe nge-galvanized okanye i-Phenolic resin ukunciphisa amathuba okubola kwe-methylene chloride. Ukugcinwa okuncinci. Beka imiqondiso yesilumkiso apho kufanelekileyo. Indawo yokugcina kufuneka yahlulwe kwindawo yokusebenza enzima yabasebenzi kwaye kufikelelwe kwindawo ethile. Sebenzisa imibhobho yeplastiki eyenzelwe ukusetyenziswa nezinto ukukhupha izinto ezinobuthi. Izinto zinokwakha umbane ongashukumiyo onokubangela ukutsha. Gcina kwindawo epholileyo, eyomileyo, enomoya ococekileyo kude nokukhanya kwelanga ngqo.
3.Ukupakishwa kunye nokuthuthwa:Sebenzisa iibharele zentsimbi ezigqunyiweyo ukuze zivalwe, i-250kg ngebharele, i-tanker kaloliwe, imoto ingathuthwa. Ifanele igcinwe kwindawo ebandayo, emnyama, eyomileyo, enomoya owaneleyo, qaphela ukufuma.
