Methylene kloride, organic pawiri yokhala ndi formula ya mankhwala CH2Cl2, ndi madzi owoneka bwino opanda mtundu okhala ndi fungo loyipa lofanana ndi ether.Amasungunuka pang'ono m'madzi, ethanol ndi ether.Pazikhalidwe zabwinobwino, ndi chosungunulira chosayaka chokhala ndi malo owira otsika.Mpweya wake ukakhala wochuluka kwambiri mumlengalenga wotentha kwambiri, umatulutsa mpweya wosakanikirana woyaka, womwe umagwiritsidwa ntchito m'malo mwa mafuta oyaka moto, ether, etc.
Katundu:Koyeramethylene kloridealibe flash point.Zosungunulira zomwe zili ndi ma voliyumu ofanana a dichloromethane ndi mafuta, zosungunulira za naphtha kapena toluene sizingayaka.Komabe, pamene dichloromethane imasakanizidwa ndi acetone kapena methyl Chemicalbook mowa wamadzimadzi mu 10: 1 chiŵerengero cha kusakaniza, kusakaniza kumakhala ndi kung'anima, nthunzi ndi mpweya kuti apange kusakaniza kophulika, malire a kuphulika 6.2% ~ 15.0% (volume).
APPLICATION:
1. Amagwiritsidwa ntchito ngati fumigation yambewu ndi firiji ya firiji yotsika kuthamanga komanso mpweya wowongolera mpweya.
2, Ntchito monga zosungunulira, extractant, mutagenic agent.
3, Amagwiritsidwa ntchito pamakampani opanga zamagetsi.Nthawi zambiri amagwiritsidwa ntchito ngati choyeretsa pochotsa mafuta.
4, Imagwiritsidwa ntchito ngati mankhwala oletsa mano am'deralo, refrigerant, chozimitsira moto, kuyeretsa zitsulo pamwamba ndi kuchotsera mafuta.
5, Ntchito ngati wapakatikati mu kaphatikizidwe organic.
Njira yokonzekera:
1. Njira yothira chlorine gasi Gasi wachilengedwe amakumana ndi mpweya wa chlorine.Pambuyo pa hydrochloric acid yopangidwa ndi hydrogen chloride ikamwedwa ndi madzi, chotsalira cha hydrogen chloride chimachotsedwa ndi lye, ndipo chomalizidwacho chimapezeka mwa kuyanika, kuponderezana, condensation ndi distillation.
2. Chloromethane ndi chloromethane anachita ndi mpweya wa chlorine pansi pa 4000kW kuwala kuti apange dichloromethane, yomwe inamalizidwa ndi kutsuka kwa alkali, kuponderezana, condensation, kuyanika ndi kukonza.Chotsatira chachikulu ndi trichloromethane.
Chitetezo:
1.Kusamala pogwira ntchito:Pewani kugwa kwa chifunga pamene mukugwira ntchito, ndipo valani zida zoyenera zodzitetezera.Pewani kutulutsa madontho a nthunzi ndi chifunga mumlengalenga wa malo ogwirira ntchito.Gwirani ntchito pamalo enaake okhala ndi mpweya wabwino ndikutenga ndalama zochepa.Zipangizo zothandizira mwadzidzidzi ziyenera kupezeka nthawi zonse kuti zithetse moto komanso kuthana ndi kutaya.Zotengera zopanda kanthu zosungira zithabe kukhala ndi zotsalira zowopsa.Osagwira ntchito pafupi ndi zowotcherera, moto, kapena pamalo otentha.
2.Kusamala posungira:Sungani pamalo ozizira, owuma, opanda mpweya wabwino popanda kuwala kwa dzuwa.Sungani kutali ndi gwero la kutentha, lawi ndi zosagwirizana monga oxidant wamphamvu, asidi wamphamvu ndi nitric acid.Sungani mu chidebe cholembedwa bwino.Zotengera zosagwiritsidwa ntchito ndi ng'oma zopanda kanthu ziyenera kuphimbidwa mwamphamvu.Pewani kuwonongeka kwa chidebecho ndikuyang'ana thanki nthawi zonse kuti muwone zolakwika monga kusweka kapena kutaya.Zotengera zimayikidwa ndi malata kapena Phenolic resin kuti muchepetse kuwonongeka kwa methylene chloride.Zosungirako zochepa.Lembani zizindikiro zochenjeza ngati kuli koyenera.Malo osungiramo katundu ayenera kupatulidwa ndi malo ogwira ntchito kwambiri ogwira ntchito komanso kuti asamalowe m'deralo.Gwiritsani ntchito mapaipi apulasitiki opangidwa kuti azigwiritsidwa ntchito ndi zinthu kuti azitulutsa poizoni.Zinthuzi zitha kupanga magetsi osasunthika omwe angayambitse kuyaka.Sungani pamalo ozizira, owuma, abwino mpweya wabwino kutali ndi dzuwa.
3.Kupaka ndi mayendedwe:Gwiritsani ntchito migolo yachitsulo yotsekedwa, 250kg pa mbiya, tanker ya sitima, galimoto ikhoza kunyamulidwa.Iyenera kusungidwa pamalo ozizira, amdima, owuma, abwino mpweya wabwino, kulabadira chinyezi.
