Dichloromethane Density Analysis
Dichloromethane, yokhala ndi chilinganizo chamankhwala CH2Cl2, chomwe chimadziwikanso kuti methylene chloride, ndi chosungunulira wamba chomwe chimagwiritsidwa ntchito kwambiri mumankhwala, mankhwala, chodulira utoto, degreaser ndi zina. Maonekedwe ake, monga kachulukidwe, malo otentha, malo osungunuka, ndi zina zotero, ndizofunikira kwambiri pakugwiritsa ntchito mafakitale. Mu pepala ili, tisanthula mwatsatanetsatane katundu wofunikira wa kachulukidwe ka dichloromethane ndikuwona kusintha kwake pamikhalidwe yosiyanasiyana.
Chidule chachidule cha kuchuluka kwa dichloromethane
Kachulukidwe ka dichloromethane ndi gawo lofunikira lomwe limayesa kuchuluka kwa gawo lililonse la chinthucho. Kutengera zoyeserera pamikhalidwe yokhazikika (ie, 25°C), kachulukidwe ka methylene chloride ndi pafupifupi 1.325 g/cm³. Izi kachulukidwe mtengo amalola methylene kolorayidi ntchito bwino olekanitsidwa ndi madzi, zinthu mafuta ndi zina zosungunulira organic mu ntchito mafakitale. Chifukwa cha kachulukidwe kake kuposa madzi (1 g/cm³), methylene chloride nthawi zambiri imamira pansi pamadzi, zomwe zimapangitsa kuti wogwiritsa ntchito asiyanitse madzi kudzera pa zida zolekanitsa monga zopangira ma fayilo.
Zotsatira za kutentha pa kachulukidwe ka methylene chloride
Kuchuluka kwa methylene chloride kumasintha ndi kutentha. Kawirikawiri, kachulukidwe ka chinthu kumachepa pamene kutentha kumawonjezeka, chifukwa cha kuwonjezeka kwa maselo, zomwe zimapangitsa kuti chiwonjezeko chiwonjezeke. Pankhani ya methylene chloride, pakatentha kwambiri kachulukidwe kake kamakhala kotsika pang'ono kuposa kutentha. Choncho, m'mafakitale, ogwiritsa ntchito amafunika kukonza kachulukidwe ka methylene chloride pazikhalidwe zinazake za kutentha kuti zitsimikizire kulondola kwa ndondomekoyi.
Zotsatira za kukakamizidwa pa kachulukidwe ka methylene chloride
Ngakhale zotsatira za kupanikizika kwa madzi amadzimadzi ndizochepa poyerekeza ndi kutentha, kachulukidwe ka methylene chloride akhoza kusintha pang'ono pansi pa kuthamanga kwambiri. Pansi pazovuta kwambiri, mtunda wa intermolecular umachepetsedwa, zomwe zimabweretsa kuwonjezeka kwa kachulukidwe. M'mafakitale apadera, monga kutulutsa kuthamanga kwambiri kapena njira zochitira, ndikofunikira kumvetsetsa ndikuwerengera kuchuluka kwa mphamvu ya methylene chloride.
Dichloromethane Density vs. Other Solvents
Kuti mumvetse bwino zakuthupi za methylene chloride, kachulukidwe kake nthawi zambiri amafanizidwa ndi zosungunulira zina zodziwika bwino. Mwachitsanzo, ethanol imakhala ndi kachulukidwe pafupifupi 0.789 g/cm³, benzene imakhala ndi kachulukidwe pafupifupi 0.874 g/cm³, ndipo chloroform imakhala ndi kachulukidwe pafupifupi 1.489 g/cm³. Zitha kuwoneka kuti kachulukidwe ka methylene chloride ali pakati pa zosungunulira izi ndipo m'machitidwe ena osakanikirana osungunulira kusiyana kwa kachulukidwe kungagwiritsidwe ntchito pakulekanitsa koyenera komanso kusankha.
Kufunika kwa kachulukidwe ka dichloromethane pazogwiritsa ntchito mafakitale
Kuchuluka kwa Dichloromethane kumakhudza kwambiri ntchito zake zamafakitale. Muzochitika zogwiritsira ntchito monga zosungunulira zosungunulira, kaphatikizidwe ka mankhwala, zoyeretsera, etc., kachulukidwe ka dichloromethane kumatsimikizira momwe zimayendera ndi zinthu zina. Mwachitsanzo, m'makampani opanga mankhwala, mphamvu ya methylene chloride imapangitsa kuti ikhale yabwino pochotsa. Chifukwa cha kuchuluka kwake, methylene chloride imalekanitsa mwachangu ndi gawo lamadzi panthawi yogawa, ndikuwongolera magwiridwe antchito.
Chidule
Pofufuza kachulukidwe ka methylene chloride, titha kuwona kuti kachulukidwe kake kamakhala ndi gawo lalikulu pamafakitale. Kumvetsetsa ndikuwongolera kusintha kwa kachulukidwe ka dichloromethane pansi pa kutentha ndi kupanikizika kosiyanasiyana kungathandize kukhathamiritsa kapangidwe kake ndikuwongolera kupanga bwino. Kaya mu labotale kapena kupanga mafakitale, deta yolondola ya kachulukidwe ndiyo maziko owonetsetsa kuti njira zama mankhwala zikuyenda bwino. Choncho, kufufuza mozama za kachulukidwe ka methylene chloride ndikofunika kwambiri kwa akatswiri amakampani opanga mankhwala.
