Malo otentha a Ethylene Glycol ndi kusanthula kwake katundu wamankhwala
M'makampani opanga mankhwala, ethylene glycol (Ethylene Glycol) ndi mankhwala ofunika kwambiri omwe amagwiritsidwa ntchito kwambiri m'madera osiyanasiyana monga antifreeze ndi kupanga utomoni. Kumvetsetsa physicochemical properties a Ethylene Glycol, makamaka kuwira kwake, n'kofunika kwambiri pa ntchito yake m'makampani. M'nkhaniyi, kuwira nsonga ya ethylene glycol ndi zake zogwirizana chikoka zinthu tikambirana mwatsatanetsatane.
Katundu Woyamba wa Ethylene Glycol ndi Malo Owiritsa ake
Ethylene glycol ndi madzi a viscous opanda mtundu, opanda fungo, onunkhira bwino okhala ndi mankhwala a C₂H₆O₂. Monga diol, ethylene glycol imakhala ndi hygroscopicity yamphamvu komanso kusungunuka kwabwino. Kuwira kwa ethylene glycol ndi 197.3 ° C. Mtengo uwu, woyezedwa ndi kuthamanga kwa mumlengalenga, umawonetsa kukhazikika kwa kapangidwe kake ka maselo ndi mphamvu ya ma intermolecular hydrogen bond.
Zomwe zimakhudza kuwira ndi kufunikira kwake kwa mafakitale
Kuwira kwa ethylene glycol kumakhudzidwa ndi zinthu zingapo. Kulumikizana kwa haidrojeni mu kapangidwe ka maselo kumakhudza kwambiri powira. Molekyu ya ethylene glycol ili ndi magulu awiri a hydroxyl (-OH), omwe amalumikizidwa ndi ma hydrogen bond, kupangitsa mphamvu za intermolecular za ethylene glycol kukhala zamphamvu ndikupangitsa kuti pakhale kutentha kwambiri. Kulemera kwa molekyulu ya ethylene glycol kumakhudzanso kuwira kwake, ndi zolemera zazikulu zamamolekyu zomwe zimafuna mphamvu zambiri kuti ziwonongeke.
M'mafakitale, kuwira kwa ethylene glycol kumakhudza kwambiri ntchito yake monga zosungunulira, zoziziritsa kukhosi ndi zinthu zina. Mwachitsanzo, kuwira kwapamwamba kumapangitsa glycol kukhala yokhazikika komanso yosasunthika pa kutentha kwakukulu, motero kuonetsetsa kuti mphamvu yake ikugwira ntchito muzozizira ndi antifreeze.
Kusamala pogwiritsira ntchito
Mukamagwiritsa ntchito ethylene glycol, chidwi chimayenera kuperekedwa pakulumikizana kwa malo otentha ndi zinthu zina. Mwachitsanzo, muzinthu zophatikizika kapena zosakanikirana, zinthu zina zimatha kukhudza kuwira kwa ethylene glycol ndipo motero zinthu zomaliza za mankhwalawa. Kudziwa kuwira kwa ethylene glycol kungathandizenso kukhathamiritsa njira zopangira mafakitale, monga kuwongolera kutentha panthawi ya distillation ndi ndende.
Mwachidule, kumvetsetsa kuwira kwa ethylene glycol ndikofunikira pakugwiritsa ntchito mafakitale. Pomvetsetsa katundu wakuthupi wa ethylene glycol, ntchito yake pakupanga ndi kugwiritsa ntchito ikhoza kuyendetsedwa bwino kuti ipititse patsogolo khalidwe ndi kukhazikika kwa mankhwala.
