Methylene chloride, chinhu cheorganic chine fomura yemakemikari CH2Cl2, imvura isina ruvara inopenya ine hwema hunopisa hwakafanana ne ether. Inonyungudika zvishoma mumvura, ethanol ne ether. Mumamiriro ezvinhu akajairwa, i solvent isingatsvi ine poindi shoma yekufashaira. Kana utsi hwayo hwava huwandu hwakanyanya mumhepo inopisa zvakanyanya, inoburitsa gasi rakasanganiswa rinopisa zvishoma, iro rinowanzoshandiswa kutsiva petroleum ether, ether, nezvimwewo.
Zvivakwa:Yakachenamethylene chloridehaina flash point. Zvinonyungudutsa zvine huwandu hwakaenzana hwe dichloromethane nepeturu, solvent naphtha kana toluene hazvibatike. Zvisinei, kana dichloromethane ikasanganiswa neacetone kana methyl Chemicalbook alcohol liquid mu 10: 1 ratio yekusanganisa, musanganiswa une flash point, utsi nemhepo kuti zvigadzire musanganiswa unoputika, muganho wekuputika 6.2% ~ 15.0% (vhoriyamu).
KUSHANDISA:
1. Inoshandiswa pakupisa zviyo nekuisa mufiriji nemhepo inotonhodza zvine simba shoma.
2, Inoshandiswa semushonga unonyungudutsa, unoburitsa, uye unochinja-chinja.
3, Inoshandiswa muindasitiri yezvemagetsi. Inowanzoshandiswa semushonga wekuchenesa kubvisa oiri.
4, Inoshandiswa semushonga wemazino wemunzvimbo, mushonga wekuisa mufiriji, mushonga wekudzimisa moto, mushonga wekuchenesa nekubvisa mafuta pamusoro pesimbi.
5, Inoshandiswa sechikamu chepakati mukugadzirwa kwezvinhu zvakasikwa.
Nzira yekugadzirira:
1. Maitiro ekugadzira chlorine mugasi rechisikigo Gasi rechisikigo rinoita chlorine negasi. Mushure mekunge hydrochloric acid inogadzirwa nehydrogen chloride yanyudzwa nemvura, hydrogen chloride inosara inobviswa ne lye, uye chigadzirwa chapera chinowanikwa kuburikidza nekuomesa, kudzvanya, kupfava uye kudiridza.
2. Chloromethane nechloromethane zvakasangana negesi rechlorine pasi pechiedza che4000kW zvikaburitsa dichloromethane, iyo yakapedzwa nekusuka, kudzvanya, kuomesa, kuomesa uye kugadzirisa. Chinhu chikuru chakagadzirwa itrichloromethane.
Kuchengetedzwa:
1.Nzira dzekudzivirira pakushanda:Dzivisai madonhwe emhute panguva yekushanda, uye pfekai michina yekudzivirira yakakodzera. Dzivisai kuburitsa mhute nemadonhwe emhute mumhepo yenzvimbo yebasa. Shandai munzvimbo ine mhepo yakanaka uye torai huwandu hushoma. Midziyo yekupindura panguva yenjodzi inofanira kuwanikwa nguva dzese kuti irwise moto uye igadzirise marara. Magaba asina chinhu ekuchengetera anogona kunge achiri netsvina ine njodzi. Musashande pedyo nepanosangana welding, moto, kana nzvimbo dzinopisa.
2.Zvidziviriro zvekuchengetedza:Chengeta munzvimbo inotonhorera, yakaoma, ine mhepo yakanaka isina chiedza chezuva chakananga. Chengeta kure nekupisa, murazvo uye kusawirirana kwakadai se strong oxidant, strong acid uye nitric acid. Chengeta mumudziyo une manyorerwo akakodzera. Madhiramu asina kushandiswa uye madhiramu asina chinhu anofanira kuvharwa zvakasimba. Dzivisa kukuvara kwemudziyo uye tarisa tangi nguva nenguva kuti uone kana paine zvikanganiso zvakaita sekutyoka kana kudururwa kwemvura. Madhiramu akafukidzwa ne galvanized kana Phenolic resin kuderedza mukana wekuora kwemethylene chloride. Kuchengetera kushoma. Isa zviratidzo zvekunyevera pazvinenge zvakakodzera. Nzvimbo yekuchengetera inofanira kuparadzaniswa nenzvimbo yebasa rinoitwa nevashandi vakawanda uye nzvimbo yacho inofanira kuvharirwa. Shandisa mapaipi epurasitiki akagadzirirwa kushandiswa nezvinhu zvinoburitsa zvinhu zvine chepfu. Zvinhu zvacho zvinogona kuungana nemagetsi asingachinji izvo zvinogona kukonzera kutsva. Chengeta munzvimbo inotonhorera, yakaoma, ine mhepo yakanaka kure nezuva rakananga.
3.Kurongedza nekutakura:Shandisa mabara esimbi akavharirwa kuti avharwe, 250kg pabhare rimwe nerimwe, tangi rechitima, mota inogona kutakurwa. Inofanira kuchengetwa munzvimbo inotonhora, ine rima, yakaoma, ine mhepo yakanaka, teerera hunyoro.
