Ethylene Glycol Boiling Point ndi Kuwunika Kwake Kwazinthu Zomwe Zimakhudza
Ethylene glycol (Ethylene Glycol) ndi mankhwala omwe amagwiritsidwa ntchito kwambiri, amagwiritsidwa ntchito kwambiri mu antifreeze, resins, plastics, solvents ndi zina. Pakupanga mankhwala ndi kugwiritsa ntchito, kumvetsetsa zakuthupi za Ethylene Glycol, makamaka malo otentha a Ethylene Glycol, ndikofunikira pakuwongolera magawo ndikuwonetsetsa kuti zinthu zili bwino.
Mwachidule za zinthu zoyambira ndi kuwira kwa ethylene glycol
Ethylene glycol ndi madzi opanda mtundu, opanda fungo, ma viscous okhala ndi mankhwala a C2H6O2. imakhala ndi kuwira kwapamwamba kwambiri kwa 197.3 ° C (pakuthamanga kwa mumlengalenga). Mkulu kuwira mfundo ya ethylene glycol amapatsa bata mu ntchito zambiri mafakitale, makamaka m`kati zimafunika kugwira ntchito pa kutentha, kumene akhoza kukhala mu madzi boma, motero kusintha njira dzuwa.
Zomwe zimakhudza kuwira kwa ethylene glycol
Malo otentha a ethylene glycol samangokhudzidwa ndi mapangidwe ake a maselo ndi mphamvu za intermolecular, komanso amagwirizana kwambiri ndi zinthu zakunja zachilengedwe. Izi ndi zina mwa zifukwa zazikulu:
Mphamvu ya kuthamanga: Pakuthamanga kwa mumlengalenga, malo otentha a ethylene glycol ndi 197.3 ° C. Ngati kupanikizika kwa dongosolo kumasintha, malo otentha adzasinthanso. Kawirikawiri, kutentha kumakwera pamene kupanikizika kumawonjezeka, ndipo izi ndizofunikira kwambiri pamagetsi othamanga kwambiri kapena ma distillations apamwamba.

Kukhalapo kwa Zonyansa: Malo otentha a ethylene glycol akhoza kusintha ngati ali ndi zonyansa. Zonyansa zina zimatha kuchepetsa kuwira kwa ethylene glycol, pomwe zina zingayambitse kuwirako. Izi zimayika zofunikira kwambiri pakuwongolera chiyero cha glycol pakupanga mafakitale.

Mphamvu Yothetsera Mavuto: Pamene glycol imagwiritsidwa ntchito monga zosungunulira kapena co-solvent, malo ake otentha amakhudzidwa ndi solute. Mwachitsanzo, glycol ikasakanizidwa ndi madzi, malo otentha a osakaniza angakhale otsika kuposa a glycol kapena madzi oyera. Kumvetsetsa katunduyu n'kofunika kwambiri pakupanga ndi kugwiritsira ntchito machitidwe azinthu zambiri kuphatikizapo ma glycols.

Kugwiritsa ntchito Glycol Boiling Point mu Viwanda
Popanga mafakitale, malo otentha a ethylene glycol ndi gawo lofunikira pakupanga ma reactors, mizati ya distillation ndi zida zina. Makamaka pakuchita kutentha kwambiri, chidziwitso cholondola cha kutentha kwa ethylene glycol kumathandiza kupewa kuwonongeka kwa kutentha ndikuwonetsetsa kukhazikika kwa zomwe zimachitika. Mu njira ya distillation ndi kulekana, kudziwa kuwira kungathandize kulamulira ndendende mikhalidwe kulekana ndi kukonza mankhwala chiyero.
Mapeto
Malo otentha a ethylene glycol ndi gawo lofunika kwambiri la thupi lomwe limakhudzidwa ndi zinthu zosiyanasiyana. Kumvetsetsa ndikuzindikira mawonekedwe owira a ethylene glycol kungathandize kukhathamiritsa ntchito yopanga mafakitale ndikuwongolera mtundu wazinthu. M'malo mwake, mainjiniya amayenera kuganizira zinthu monga kupanikizika, zonyansa komanso njira zothetsera vutoli kuti agwiritse ntchito mokwanira mawonekedwe a ethylene glycol ndikuwonetsetsa kuti ntchito yokhazikika komanso yothandiza.
