Chigadzirwa Chekutanga
Richemical chemical is nyanzvi yeChina suphizimusi yeindasitiri giredhi dichlomethane yakagadzirwa muChina, iyo yanga yatoita mumakemikari emakore gumi. Tinokupa yemahara sampuli, tinokugamuchira neushamwari kuti utenge iwe wakakwira mhando CAS HOPE. Makemikari nekuchena kwakanyanya uye mutengo wakaderera nesu.
Chigadzirwa Chinhu
Molecular Formula: Ch2Cl2
Solecular uremu: 84.93
Zvepanyama uye zvemakemikari zvivakwa: mavara asina mavara akajeka akajeka, akafanana nekunhuhwirira kwe ether uye anotapira.
Yevaridzi Density: D4201.326KG / L.
Boling Point: 40.4 deg c.
Inonyungudika Pfungwa: -96.7 madhigirii, iyo yekukasira ye615 deg c. zvishoma nezvishoma inonyudza mumvura, svutugadzike mu ethanol, ethyl ether, ane muchetura, netcotic kukurudzira. Dichlomethane uye Mvura Hydrolysis Reaction, Dichlomethane ine ekutengesa stabilizer, kudzivirira hydrolysis. Dichlomethane uye yakakwirira misheni okisijeni ichagadzira musanganiswa unoputika, asi kwete kupisa, zvinowanzoshandiswa mune indasitiri yekudzikisira kwechinhu chakaderera, isina kupenya solvent uye yakaderera inovhara.
Chinangwa
Zvekuti usiri kupisa solvent: simbi yekuchenesa, pendi remover, simbi degreasing mumiririri, matatu cellulose acetate solvent; Firimu, Aerosol, mishonga inorwisa mabhakitiriya uye mavitamini mukugadzirwa kweiyo solvent; Kupisa mumiririri wekupupuma kwekugadzirwa kweinjiniya mapurasitiki; murazvo unodzora zvigadzirwa; yaishandiswa kutsiva F11 uye F12 kushandiswa kweiyo synthesis zvigadzirwa; zvigadzirwa zvakanaka zvemakemikari.
Kurongedza, kuchengetedza uye zvekufambisa
Gallanized Simbi, Dhigedhi Steel Drum kana Tank Yakacherechedzwa Pairating Container inozadza vhoriyamu yeDichlomethane, iyo 80%, inogona kupa nitrogen kuchengetedzwa kwevashandisi nezvinodiwa nezvinodiwa. Chengetedza chinofanira kuchengetwa munzvimbo inotonhorera uye yakaoma, iyo yekuchengetera inofanira kunge ichipinda kuti udzivise kusangana neyakanyanya kurongeka kweokisijeni kana kudzivirira kusangana nemvura kuitira kudzivirira hydrolysis. Iko kutakurwa kuchatevedzera zviwanikwa zvevanhu republic of China maererano nekutakurwa kwemakemikari ane ngozi nemigwagwa mikuru uye nzira dzechitima.
Hutano uye Kuchengeteka
Sichlomethane mukuputika kwemhepo Limit: 8.1 ~ 17.2%, ndezvemakemikari anowoneka. Kuwedzeredza kwakanyanya, nguva yakareba kuratidzwa nyore kuita kuti uzive, kusvina, tinnitus kana kuonda kwemakumbo, famba uchienda kumhepo, zviratidzo zvinokurumidza kudzorerwa, hazvizokonzere kukuvara zvachose. Splash mumaziso anokonzeresa kurwadziwa uye kushatirisa, kwenguva refu kusangana neganda kunogona kukonzera dermatitis.
