Malo otentha a dichloromethane: zidziwitso ndi kugwiritsa ntchito
Dichloromethane, yokhala ndi mankhwala opangidwa ndi CH₂Cl₂, ndi madzi opanda mtundu, onunkhira bwino omwe amagwiritsidwa ntchito kwambiri m'makampani ndi ma laboratories. Monga chosungunulira chofunikira cha organic, chimakhala ndi gawo lalikulu pamachitidwe ambiri amankhwala chifukwa cha mawonekedwe ake apadera. Mu pepala ili, tiwona mozama nsonga yowira ya methylene chloride ndikusanthula kufunikira kwake pakugwiritsa ntchito.
Mwachidule za Boiling Point ya Methylene Chloride
Methylene chloride ali ndi kuwira kwa 39.6°C. Kutentha kotentha kumeneku kumapangitsa kuti zisasunthike kwambiri pa kutentha kwapakati. Dichloromethane ili ndi malo otentha otsika kwambiri kuposa zosungunulira zina zambiri, choncho nthawi zambiri imasankhidwa panjira zomwe zimafuna kuti zosungunulira zisungunuke mwachangu. Malo otenthawa amapangitsa kuti methylene chloride ikhale yabwino kwambiri pakubwezeretsa zosungunulira ndi kuyanika, zomwe zimapangitsa kuti mpweya umalizike bwino.
Zomwe zimakhudza kuwira kwa methylene chloride
Ngakhale methylene chloride ili ndi kuwira kwa 39.6 ° C, kutentha kumeneku sikukhazikika. Malo otentha amatha kukhudzidwa ndi zinthu zingapo, monga kuthamanga kwa mlengalenga, chiyero ndi zigawo zina mu osakaniza. Pakuthamanga kwa mumlengalenga, malo otentha a methylene chloride amakhala okhazikika. Kuthamanga kwa mlengalenga kumasintha, mwachitsanzo pamtunda wapamwamba, kutentha kumachepa pang'ono. Kuyera kwa methylene chloride kumakhudzanso kuwira kwake, ndipo kukhalapo kwa zonyansa kungayambitse kusinthasintha kwakung'ono pakuwira.
Dichloromethane kuwira malo mu ntchito mafakitale
Dichloromethane imagwiritsidwa ntchito kwambiri m'makampani chifukwa cha kuwira kwake kochepa, makamaka pakuchotsa ndi kuyeretsa. Chifukwa cha kuthekera kwake kusungunuka mwachangu komanso kusungunuka kwake kwabwino, methylene chloride imagwiritsidwa ntchito pochotsa mafuta, utomoni ndi zinthu zina zachilengedwe. M'makampani opanga mankhwala, amagwiritsidwa ntchito ngati zosungunulira kuti achotse zosakaniza zogwira ntchito komanso pokonzekera mankhwala omaliza kuti achotse mwamsanga zosungunulira zotsalira kuti zitsimikizire chiyero cha mankhwala.
Chidule
Methylene chloride imakhala ndi kuwira kwa 39.6 ° C, chinthu chomwe chimapangitsa kuti ikhale yosungunulira yofunika kwambiri pamakampani opanga mankhwala. Kumvetsetsa komanso kudziwa bwino momwe ma methylene chloride amawotchera amatha kuthandizira akatswiri amakampani opanga mankhwala kupanga bwino komanso kukonza njira zopangira. Mu ntchito zothandiza, kugwiritsa ntchito kuwira mfundo ya methylene kolorayidi molumikizana ndi kusintha kwa chilengedwe ndi chiyero cha zinthu akhoza kwambiri kusintha ndondomeko dzuwa ndi khalidwe mankhwala.
