Kuchulukana kwa dichloromethane: Kuyang'ana mozama pa chinthu chofunikira ichi
Methylene chloride (mankhwala formula: CH₂Cl₂), yomwe imadziwikanso kuti chloromethane, ndi madzi opanda mtundu, onunkhira bwino omwe amagwiritsidwa ntchito kwambiri pamakampani opanga mankhwala, makamaka ngati zosungunulira. Kumvetsetsa kuchuluka kwa kachulukidwe ka methylene chloride ndikofunikira kuti igwiritsidwe ntchito m'makampani. M'nkhaniyi, tikambirana za kachulukidwe ka methylene chloride mwatsatanetsatane komanso momwe katunduyu amakhudzira kugwiritsidwa ntchito kwake pamakina.
Kodi kachulukidwe ka methylene chloride ndi chiyani?
Kachulukidwe ndi chiŵerengero cha kulemera kwa chinthu ndi kuchuluka kwake ndipo ndi chizindikiro chofunika kwambiri chowonetsera chinthu. Kuchulukana kwa methylene chloride ndi pafupifupi 1.33 g/cm³ (pa 20°C). Kachulukidwe kameneka kakusonyeza kuti methylene chloride ndi yolimba pang'ono kuposa madzi (1 g/cm³) pa kutentha komweko, kutanthauza kuti ndiyolemera pang'ono kuposa madzi. Kachulukidwe kake kameneka kamalola methylene chloride kuwonetsa machitidwe apadera pazinthu zambiri, mwachitsanzo munjira zolekanitsa zamadzimadzi, pomwe nthawi zambiri zimakhala pansi pamadzi.
Zotsatira za kutentha pa kachulukidwe ka methylene chloride
Kuchuluka kwa methylene chloride kumasiyanasiyana ndi kutentha. Kawirikawiri, kuchuluka kwa methylene chloride kumachepa pamene kutentha kumawonjezeka. Izi ndichifukwa chakuchulukirachulukira kwa mamolekyu chifukwa cha kutentha kwambiri, komwe kumachepetsa kuchuluka kwa kuchuluka kwa ma unit. Mwachitsanzo, pakatentha kwambiri, kuchuluka kwa methylene chloride kumatha kutsika pansi pa 1.30 g/cm³. Kusintha kumeneku n'kofunika pazochitika za mankhwala kumene kuwongolera bwino kwa zosungunulira kumafunika, monga kutulutsa kapena kupatukana, kumene kusintha kwakung'ono kwa kachulukidwe kungakhudze kwambiri zotsatira za ntchito. Kutengera kutentha kwa kachulukidwe kuyenera kuganiziridwa mosamala popanga njira zophatikizira methylene chloride.
Zotsatira za kachulukidwe ka dichloromethane pamagwiritsidwe ake
Kuchuluka kwa Dichloromethane kumakhudza mwachindunji ntchito zake zambiri m'makampani. Chifukwa cha kachulukidwe kake, dichloromethane ndi chosungunulira chamadzimadzi-chamadzimadzi ndipo chimakhala choyenera makamaka kupatukana kwazinthu zachilengedwe zomwe sizimalumikizana ndi madzi. Imagwiranso ntchito ngati chosungunulira chabwino kwambiri popanga utoto, mankhwala, ndi mankhwala. Kachulukidwe ka methylene chloride imapangitsa kuti iziwonetsa mawonekedwe apadera potengera kusungunuka kwa gasi komanso kuthamanga kwa nthunzi, ndipo imagwiritsidwanso ntchito kwambiri popanga thovu, zochotsera utoto ndi ntchito zina.
Chidule
Katundu wakuthupi wa dichloromethane density amatenga gawo lofunikira pamakampani opanga mankhwala. Kumvetsetsa ndi chidziwitso cha chizindikiro ichi sikungothandiza kukhathamiritsa ntchito za mafakitale komanso kumatsimikizira kuti zotsatira zabwino za ndondomekoyi zimatheka pazikhalidwe zosiyanasiyana za kutentha. Kupyolera mu kusanthula mu pepalali, akukhulupirira kuti owerenga adzatha kumvetsa mozama za kachulukidwe ka dichloromethane ndi kufunikira kwake mu ntchito za mafakitale.
