Methylene chloride, organic compound ine kemikari formula CH2Cl2, imvura inopenya isina ruvara uye inonhuwira inonhuwira yakafanana neether.Inonyungudika zvishoma mumvura, ethanol uye ether.Mumamiriro ezvinhu akajairika, chinhu chisingabatike chinonyungudutsa chine nzvimbo yakaderera yekuvira.Kana hupfu hwayo hukave hwakakwirira mumhepo yekupisa, inoburitsa gasi rakasanganiswa risina kusimba, rinowanzo shandiswa kutsiva rinopisa petroleum ether, ether, nezvimwe.
Properties:Puremethylene chloridehaina flash point.Zvinyungudutsa zvine mavhoriyamu akaenzana edichloromethane nepeturu, solvent naphtha kana toluene hazvibatike.Zvisinei, kana dichloromethane yakasanganiswa neacetone kana methyl Chemicalbook doro remvura mu10: 1 chiyero chekusanganiswa, musanganiswa une flash point, mhute nemhepo kuti iite musanganiswa unoputika, kuputika muganhu 6.2% ~ 15.0% (vhoriyamu).
APPLICATION:
1. Inoshandiswa pakuputira zviyo uye firiji yefiriji yakaderera uye air conditioning unit.
2, Inoshandiswa se solvent, extractant, mutagenic agent.
3, Inoshandiswa muindasitiri yemagetsi.Inowanzoshandiswa sechinhu chekuchenesa kubvisa mafuta.
4, Inoshandiswa semazino emunharaunda anesthetic, refrigerant, moto wekudzimisa mumiririri, simbi pamusoro pekuputira kuchenesa uye degreasing agent.
5, Inoshandiswa seyepakati mune organic synthesis.
Kugadzirira nzira:
1. Natural gasi chlorination process Gasi remusikirwo rinosangana ne chlorine gasi.Mushure mokunge hydrochloric acid inogadzirwa nehydrogen chloride inotorwa nemvura, iyo yakasara trace hydrogen chloride inobviswa nelye, uye chigadzirwa chakapedzwa chinowanikwa kuburikidza nekuomeswa, kudzvinyirira, condensation uye distillation.
2. Chloromethane uye chloromethane yakaitwa ne chlorine gas pasi pe 4000kW chiedza kuti ibudise dichloromethane, iyo yakapedzwa nealkali washing, compression, condensation, kuomesa uye kugadzirisa.Iyo huru byproduct ndeye trichloromethane.
Chengetedzo:
1.Chengetedzo yekushanda:Dzivisa kudonha kwemhute panguva yekushanda, uye pfekai midziyo yekuzvidzivirira nayo yakakodzera.Dzivisa kuburitsa mhute nemadonhwe emhute mumhepo yenzvimbo yebasa.Shanda mune imwe nzvimbo ine mhepo yakanaka uye tora shoma shoma.Emergency response equipment inofanira kuvapo nguva dzose kudzivirira moto uye kugadzirisa kurasika.Magaba ekuchengetera asina chinhu anogona kunge achiri nenjodzi.Usashande munzvimbo yewelding, murazvo, kana panopisa.
2.Kuchengetedza:Chengetedza munzvimbo inotonhorera, yakaoma, ine mhepo yakanaka isina chiedza chezuva.Chengetedza kure nekupisa kunopisa, murazvo uye kusapindirana senge yakasimba oxidant, yakasimba asidhi uye nitric acid.Chengetedza mumudziyo wakanyorwa zvakanaka.Midziyo isina kushandiswa uye madhiramu asina chinhu anofanira kunge akavharwa zvakasimba.Dzivisa kukuvadzwa kwemudziyo uye ongorora tangi nguva nenguva kuti uone kukanganisa kwakadai sekuputsika kana kupera.Midziyo inoiswa galvanized kana Phenolic resin kuderedza mukana wekuparara kwemethylene chloride.Chengetedzo shoma.Tumira zviratidzo zvekunyevera pazvinenge zvakakodzera.Nzvimbo yekuchengetera inofanirwa kuparadzaniswa kubva kune yevashandi yakadzika nzvimbo yebasa uye inorambidzwa kupinda munzvimbo.Shandisa mapaipi epurasitiki akarongedzerwa kushandiswa nezvinhu kuburitsa zvinhu zvine chepfu.Izvo zvinhu zvinogona kuvaka static magetsi izvo zvinogona kukonzera kupisa.Chengetedza munzvimbo inotonhorera, yakaoma, ine mhepo yakanaka kure nechiedza chezuva.
3.Packaging uye zvekufambisa:Shandisa galvanized iron barrel kuvharwa, 250kg per barrel, train tanker, mota inogona kutakurwa.Inofanira kuchengetwa munzvimbo inotonhora, ine rima, yakaoma, ine mhepo yakanaka, teerera kune unyoro.
