Methylene kloride, chinthu chachilengedwe chokhala ndi formula ya mankhwala CH2Cl2, ndi madzi owonekera opanda mtundu omwe ali ndi fungo lopweteka lofanana ndi ether. Amasungunuka pang'ono m'madzi, ethanol ndi ether. Munthawi yabwinobwino, ndi chosungunulira chosayaka chomwe chili ndi kutentha kochepa. Pamene nthunzi yake ikhala yochuluka mumlengalenga wotentha kwambiri, imapanga mpweya wosakanikirana woyaka pang'ono, womwe nthawi zambiri umagwiritsidwa ntchito m'malo mwa ether ya petroleum yomwe imayaka, ether, ndi zina zotero.
Katundu:Yoyeramethylene kloridiAlibe flash point. Zosungunulira zomwe zili ndi ma voliyumu ofanana a dichloromethane ndi petulo, solvent naphtha kapena toluene sizingayake. Komabe, dichloromethane ikasakanizidwa ndi acetone kapena methyl Chemicalbook alcohol liquid mu chiŵerengero cha 10: 1, chosakanizacho chimakhala ndi flash point, nthunzi ndi mpweya kuti apange chosakaniza chophulika, malire a kuphulika ndi 6.2% ~ 15.0% (voliyumu).
NTCHITO:
1. Amagwiritsidwa ntchito pofukiza tirigu ndi kuziziritsa firiji ndi makina oziziritsira mpweya otsika mphamvu.
2, Amagwiritsidwa ntchito ngati chosungunulira, chotulutsa, komanso chothandizira kusintha kwa zinthu.
3, Amagwiritsidwa ntchito mumakampani opanga zamagetsi. Amagwiritsidwa ntchito kwambiri ngati chotsukira mafuta.
4, Amagwiritsidwa ntchito ngati mankhwala oletsa ululu m'mano, choziziritsira, chozimitsira moto, choyeretsa ndi chochotsera mafuta pamwamba pa chitsulo.
5, Amagwiritsidwa ntchito ngati gawo lapakati pa kapangidwe ka organic.
Njira yokonzekera:
1. Njira yopangira chlorine m'mpweya wachilengedwe Mpweya wachilengedwe umakumana ndi mpweya wa chlorine. Madzi akamaliza kuyamwa hydrochloric acid yopangidwa ndi hydrogen chloride, hydrogen chloride yotsalayo imachotsedwa ndi lye, ndipo chinthu chomalizidwacho chimapezeka powumitsa, kupondereza, kuzizira ndi kusungunuka.
2. Chloromethane ndi chloromethane zinagwirizana ndi mpweya wa chlorine pansi pa kuwala kwa 4000kW kuti zipange dichloromethane, yomwe inatha ndi kutsukidwa ndi alkali, kukanikiza, kuzizira, kuumitsa ndi kukonzanso. Chotsatira chachikulu ndi trichloromethane.
Chitetezo:
1.Malangizo Othandizira Opaleshoni:Pewani kutayikira kwa chifunga panthawi yogwira ntchito, ndipo valani zida zoyenera zodzitetezera. Pewani kutulutsa nthunzi ndi madontho a chifunga mumlengalenga wa malo ogwirira ntchito. Gwirani ntchito pamalo enaake okhala ndi mpweya wabwino ndipo tengani kuchuluka kochepa. Zipangizo zoyankhira zadzidzidzi ziyenera kupezeka nthawi zonse kuti zithetse moto ndi kuthana ndi kutayikira. Zidebe zopanda kanthu zosungiramo zinthu zitha kukhalabe ndi zotsalira zoopsa. Musagwire ntchito pafupi ndi malo olumikizirana, malawi, kapena malo otentha.
2.Malangizo Osungira Zinthu:Sungani pamalo ozizira, ouma, komanso opumira bwino popanda kuwala kwa dzuwa mwachindunji. Sungani kutali ndi kutentha, malawi ndi zosagwirizana monga oxidant wamphamvu, asidi wamphamvu ndi nitric acid. Sungani mu chidebe cholembedwa bwino. Zidebe zosagwiritsidwa ntchito ndi migolo yopanda kanthu ziyenera kuphimbidwa bwino. Pewani kuwonongeka kwa chidebecho ndipo yang'anani thanki nthawi zonse ngati pali zolakwika monga kusweka kapena kutayikira. Zidebezo zimakutidwa ndi galvanized kapena Phenolic resin kuti muchepetse kuwonongeka kwa methylene chloride. Kusunga kochepa. Ikani zizindikiro zochenjeza ngati kuli koyenera. Malo osungiramo ayenera kulekanitsidwa ndi malo ogwirira ntchito ambiri komanso malo ocheperako olowera. Gwiritsani ntchito mapaipi apulasitiki omwe amapangidwira kuti agwiritsidwe ntchito ndi zinthu zotulutsa zinthu zapoizoni. Zinthuzo zitha kupanga magetsi osasinthasintha omwe angayambitse kuyaka. Sungani pamalo ozizira, ouma, komanso opumira bwino kutali ndi kuwala kwa dzuwa mwachindunji.
3.Kulongedza ndi mayendedwe:Gwiritsani ntchito migolo yachitsulo yopangidwa ndi galvanized kuti mutseke, 250kg pa mbiya iliyonse, sitima yapamadzi, galimoto ikhoza kunyamulidwa. Iyenera kusungidwa pamalo ozizira, amdima, ouma, komanso opumira bwino, samalani ndi chinyezi.
