Nhanganyaya yeChigadzirwa
Rich Chemical ikambani yehunyanzvi yekuChina inopa dichloromethane yemhando yepamusoro inogadzirwa muChina, iyo yave ichishandiswa mumakemikari eorganic kwemakore gumi. Tichipa sampuro yemahara, tinokugamuchirai nemufaro kuti mutenge makemikari eCAS No. emhando yepamusoro ane kuchena kwakanyanya uye mutengo wakaderera nesu.
Ruzivo rwechigadzirwa
Fomura yemorekuru: CH2CL2
Kurema kwemamorekuru: 84.93
Hunhu hwemuviri nemakemikari: mvura inopenya isina ruvara, yakafanana nekunhuhwirira kwe ether ne sweet.
Kuwanda kwehuwandu: D4201.326Kg/L.
pombi yekufashaira: 40.4 DEG C.
Pokunyunguduka: -96.7 degrees, pokubvira kwemoto ye615 DEG C. Inonyunguduka zvishoma mumvura, inonyunguduka muethanol, ethyl ether, inomutsa chepfu, inodhaka. Dichloromethane uye mvura hydrolysis reaction, dichloromethane ine commercial stabilizer, kudzivirira hydrolysis. Dichloromethane uye high concentration oxygen ichaburitsa musanganiswa unoputika, asi usingabatike, unowanzoshandiswa muindasitiri yechepfu shoma, solvent isingabatike uye pokufashaira yakaderera.
Chinangwa
Zvekunyungudutsa zvisingabatike: kuchenesa simbi, kubvisa pendi, chinhu chinobvisa mafuta musimbi, chinhu chetatu che cellulose acetate solvent; firimu, aerosol, mishonga inorwisa mabhakitiriya nemavhitamini mukugadzira chinhu chinonyungudutsa; chinhu chinofuridzira furo pakugadzira mapurasitiki einjiniya; zvigadzirwa zvinodzivisa moto; chinoshandiswa kutsiva F11 neF12 pakugadzira zvigadzirwa; zvigadzirwa zvemakemikari zvakanaka.
Kurongedza, kuchengetera uye kutakurwa
Simbi yakavharidzirwa, dhiramu dema resimbi kana tangi rakavharirwa, vhoriyamu yekuzadza dichloromethane, iyo 80%, inogona kudzivirira nitrogen kune vashandisi vane zvinodiwa zvakakosha. Kuchengetera kunofanirwa kuchengetwa munzvimbo inotonhorera uye yakaoma, imba yekuchengetera zvinhu inofanira kunge ine mhepo inofefetera kudzivirira kusangana neoxygen yakawanda kana ma oxide, kudzivirira kusangana nemvura kudzivirira hydrolysis. Kutakura kunofanirwa kutevedzera zviri muPeople's Republic of China maererano nekutakura makemikari ane njodzi nemigwagwa mikuru nenjanji.
Hutano nekuchengetedzeka
Muganho wekuputika kweSichloromethane mumhepo: 8.1 ~ 17.2%, ndeyemakemikari anotsva. Kuwanda kwakawanda, kugara kwenguva refu kunokonzera dzungu, hope, kuda kurutsa, tinnitus kana kusanzwa simba remakumbo, kufamba kumhepo itsva, zviratidzo zvinodzoserwa nekukurumidza, hazvizokonzere kukuvara kwenguva refu. Kupfapfaidza mumaziso kunokonzera kurwadziwa nekutsamwa, kusangana neganda kwenguva refu kunogona kukonzera dermatitis.
