Rich Chemical inyanzvi yeChina mutengesi weindasitiri giredhi dichloromethane yakagadzirwa muChina, iyo yave ichiita organic makemikari kwemakore gumi. Kupa sampuli yemahara, tinokugamuchira noushamwari kuti utenge high quality CAS No. makemikari ane kuchena kwepamusoro uye mutengo wakaderera nesu.
Product tsanangudzo
Molecular formula: CH2CL2
Molecular uremu: 84.93
Zvenyama uye zvemakemikari zvimiro:isina ruvara inopenya inoputika mvura, yakafanana nekunhuhwirira kweether uye kutapira.
Hukama density: D4201.326Kg/L.
nzvimbo yekuvira: 40.4 DEG C.
kunyunguduka: -96.7 madhigirii, iyo ignition point ye615 DEG C. Zvishoma kunyungudika mumvura, soluble mu ethanol, ethyl ether, chepfu, narcotic stimulation. Dichloromethane uye mvura hydrolysis reaction, dichloromethane ine kutengeserana stabilizer, kudzivirira hydrolysis. Dichloromethane uye yakakwira yeokisijeni inoburitsa musanganiswa unoputika, asi usingabatike, inowanzoshandiswa muindasitiri yehupfu hwakadzika, isingabatike zvinonyungudutsa uye nzvimbo yakaderera yekubikira.
Chinangwa
Kune isingabatike solvent: kuchenesa simbi, pendi inobvisa, metal degreasing agent, matatu cellulose acetate solvent; firimu, aerosol, mishonga inorwisa mabhakitiriya uye mavitamini mukugadzirwa kwe solvent; foaming agent yekupupa kwekugadzirwa kweinjiniya mapurasitiki; zvigadzirwa zvinodzivirira moto; inoshandiswa kutsiva F11 uye F12 kushandiswa kwekugadzira zvigadzirwa; zvigadzirwa zvemakemikari zvakanaka.
Kurongedza, kuchengetedza uye kutakura
Simbi yakagadziridzwa, dhiramu dema resimbi kana tangi yakavharwa yekurongedza yekuzadza vhoriyamu yedichloromethane, iyo 80%, inogona kupa nitrogen kuchengetedza kune vashandisi vane zvakakosha zvinodiwa. Kuchengetera kunofanirwa kuchengetwa munzvimbo inotonhorera uye yakaoma, imba yekuchengetera inofanirwa kufefeterwa kuti isasangana neyakakura yeokisijeni kana okisijeni, kudzivirira kusangana nemvura kuitira kudzivirira hydrolysis. Chekufambisa chichatevedzera zvakatemwa nePeople's Republic of China maererano nekutakurwa kwemakemikari ane njodzi nemigwagwa mikuru nezvitima.
Utano nekuchengeteka
Sichloromethane mumhepo inoputika muganho: 8.1 ~ 17.2%, ndeyemakemikari anopisa. Yakanyanya kutarisisa, kuratidzwa kwenguva yakareba kunokonzera dzungu, kurara, kusvotwa, tinnitus kana kusanzwa kwemakumbo nemaoko, kutamira kumhepo nyowani, zviratidzo zvinokurumidza kudzoreredzwa, hazvizokonzere kukuvara kusingaperi. Kuputika mumaziso kunokonzera kurwadziwa uye kutsamwa, kubata kwenguva refu neganda kunogona kukonzera dermatitis.
