Izinyibilikisi zeKhemikhali–iMethylene Chloride Zenziwe eTshayina

Intshayelelo yeMveliso

I-Rich Chemical ngumthengisi oqeqeshiweyo waseTshayina we-dichloromethane yodidi lwemizi-mveliso eyenziwe eTshayina, ebisoloko isetyenziswa kwiikhemikhali ze-organic kangangeminyaka eli-10. Sinikezela ngesampulu yasimahla, siyakwamkela ngobubele ukuba uthenge iikhemikhali ze-CAS No. ezisemgangathweni ophezulu ezinobunyulu obuphezulu kunye nexabiso eliphantsi nathi.

Iinkcukacha zemveliso
Ifomula yemolekyuli: CH2CL2
Ubunzima bemolekyuli: 84.93
Iimpawu zomzimba nezekhemikhali: ulwelo oluguquguqukayo olungenambala, olufana nevumba le-ether kunye nelimnandi.
Uxinano oluhambelanayo: D4201.326Kg/L.
iqondo lokubila: 40.4 DEG C.
Iqondo lokunyibilika: -96.7 degrees, iqondo lokutsha le-615 DEG C. Inyibilika kancinci emanzini, inyibilika kwi-ethanol, i-ethyl ether, ivuselela ityhefu, i-narcotic. I-Dichloromethane kunye ne-hydrolysis reaction, i-dichloromethane equlethe i-commercial stabilizer, ukuthintela i-hydrolysis. I-Dichloromethane kunye ne-oxygen enoxinzelelo oluphezulu ziya kuvelisa umxube oqhumayo, kodwa awutshi, usetyenziswa kakhulu kwishishini le-toxicity ephantsi, i-solvent engatshiyo kunye ne-bolling point ephantsi.

Injongo
Kwi-solvent engatshiyo: ukucoca isinyithi, i-remover yepeyinti, i-arhente yokususa amafutha esinyithi, i-solvent ye-cellulose acetate ezintathu; ifilimu, i-aerosol, ii-antibiotics kunye neevithamini ekuvelisweni kwe-solvent; i-arhente yokukhupha amagwebu ekuvelisweni kweplastiki yobunjineli; iimveliso ezithintela ilangatye; isetyenziselwa ukuthatha indawo ye-F11 kunye ne-F12 ekuvelisweni kweemveliso; iimveliso zeekhemikhali ezintle.

Ukupakishwa, ukugcinwa kunye nokuthuthwa
Intsimbi egalelweyo, idrama yentsimbi emnyama okanye isitya sokupakisha esitywiniweyo setanki, umthamo we-dichloromethane, i-80%, unokubonelela ngokhuseleko lwe-nitrogen kubasebenzisi abaneemfuno ezikhethekileyo. Indawo yokugcina kufuneka igcinwe kwindawo epholileyo neyomileyo, indawo yokugcina impahla kufuneka ingeniswe umoya ukuze kuthintelwe ukudibana noxinzelelo oluphezulu lweoksijini okanye ii-oxide, ukuze kuthintelwe ukudibana namanzi ukuze kuthintelwe i-hydrolysis. Uthutho kufuneka luhambelane nemimiselo yeRiphabliki yaseTshayina malunga nokuthuthwa kweekhemikhali eziyingozi ngeendlela ezinkulu nangoololiwe.

Impilo nokhuseleko

Umda wokuqhuma komoya yiSichloromethane: 8.1 ~ 17.2%, yeyamakhemikhali atshayo. Uxinzelelo oluphezulu, ukuvezwa ixesha elide kubangela lula isiyezi, ukozela, isicaphucaphu, i-tinnitus okanye ukungaziva kakuhle kwamalungu omzimba, ukufudukela emoyeni omtsha, iimpawu zibuyela umva ngokukhawuleza, aziyi kubangela umonakalo ohlala ixesha elide. Ukutshiza emehlweni kubangela iintlungu nokucaphuka, ukudibana nolusu ixesha elide kunokubangela i-dermatitis.

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