Izinyibilikisi zeMichiza-Methylene Chloride Yenziwe eTshayina

Intshayelelo yeMveliso

IChemical ecebileyo yingcali yaseTshayina umboneleli webakala leshishini le-dichloromethane elenziwe e-china, elisebenza kwiikhemikhali ze-organic iminyaka eyi-10.Ukunikezela ngesampuli yamahhala, siyakwamkela ngokufudumeleyo ukuba uthenge umgangatho ophezulu we-CAS No. iikhemikhali ezinobunyulu obuphezulu kunye nexabiso eliphantsi kunye nathi.

Iinkcukacha zemveliso
Ifomula yemolekyuli: CH2CL2
Ubunzima bemolekyuli: 84.93
Iimpawu zomzimba kunye neekhemikhali:ulwelo olungenambala olungenambala oluguquguqukayo, olufana nevumba le-ether kunye neswiti.
Uxinzelelo olunxulumeneyo: D4201.326Kg/L.
iqondo lokubila: 40.4 DEG C.
indawo yokunyibilika: -96.7 degrees, indawo yokutshisa i-615 DEG C. I-soluble kancinane emanzini, i-soluble kwi-ethanol, i-ethyl ether, i-toxic, i-narcotic stimulation.I-Dichloromethane kunye ne-water hydrolysis reaction, i-dichloromethane equlethe i-stabilizer yorhwebo, ukukhusela i-hydrolysis.IDichloromethane kunye neoksijini yoxinzelelo oluphezulu iya kuvelisa umxube oqhumayo, kodwa ongatshiyo, iqhele ukusetyenziswa kwishishini letyhefu esezantsi, isinyibiliki esingatshayo kunye nenqanaba elisezantsi lokubila.

Injongo
Kwi-solvent engatshayo: ukucocwa kwesinyithi, ukususwa kwepeyinti, i-agent ye-metal degreasing, ezintathu ze-cellulose acetate solvent;ifilimu, i-aerosol, i-antibiotics kunye namavithamini ekuveliseni i-solvent;i-agent ekhupha amagwebu ukwenzela ukuveliswa kweeplastiki zobunjineli;iimveliso ezithintela amadangatye;isetyenziselwa ukubuyisela i-F11 kunye ne-F12 yokusetyenziswa ekuhlanganiseni iimveliso;iimveliso zeekhemikhali ezilungileyo.

Ukupakishwa, ukugcina kunye nokuthutha
Intsimbi yegalvanized, idrum yentsimbi emnyama okanye itanki etywiniweyo yokupakisha isikhongozeli sokuzalisa umthamo we-dichloromethane, i-80%, inokubonelela ngokukhuselwa kwe-nitrogen kubasebenzisi abaneemfuno ezizodwa.Ukugcinwa kufuneka kugcinwe kwindawo epholileyo neyomileyo, indawo yokugcina kufuneka ifakwe umoya ukuze ugweme ukudibanisa noxinzelelo oluphezulu lwe-oksijini okanye i-oxides, ukuphepha ukudibanisa namanzi ukwenzela ukukhusela i-hydrolysis.Uthutho luya kuthobela izibonelelo zePeople's Republic of China malunga nokuthuthwa kweekhemikhali eziyingozi ngoohola bendlela kunye noololiwe.

Impilo nokhuseleko

ISichloromethane kumda wokudubula komoya: 8.1 ~ 17.2%, yeyemichiza enokutsha.Ukugxininiswa okuphezulu, ukubonakaliswa kwexesha elide kubangela ukuba kube lula ukuba nesiyezi, ukozela, isicaphucaphu, i-tinnitus okanye ukuba ndikindiki kwamalungu, ukuya emoyeni omtsha, iimpawu zibuyiselwe ngokukhawuleza, aziyi kubangela umonakalo ohlala njalo.Ukutshiza emehlweni kubangela intlungu kunye nokucaphuka, ukudibanisa ixesha elide kunye nesikhumba kunokubangela i-dermatitis.

Umgangatho womgangatho we-Q/0523 JLH002-2011 methylene chloride
