Kugwiritsa ntchito kwakukulu kwa ethylene glycol ndi ngati antifreeze agent mu choziziritsa mwachitsanzo, magalimoto ndi makina oziziritsira mpweya omwe amayika zoziziritsa kukhosi kapena zowongolera mpweya kunja kapena ziyenera kuziziritsa kuzizira kwamadzi. M'makina otentha / ozizira, ethylene glycol ndi madzi omwe amanyamula kutentha pogwiritsa ntchito mpope wa kutentha kwa geothermal. The ethylene glycol mwina amapeza mphamvu kuchokera ku gwero (nyanja, nyanja, madzi chitsime) kapena dissipates kutentha kwa kumira, malinga ndi dongosolo ntchito kutentha kapena kuziziritsa.
Ethylene glycol yoyera imakhala ndi kutentha kwapadera pafupifupi theka la madzi. Chifukwa chake, popereka chitetezo chozizira komanso kuwira, ethylene glycol imachepetsa kutentha kwamadzi osakanikirana ndi madzi oyera. Kusakaniza kwa 1: 1 ndi misa kumakhala ndi kutentha kwapadera kwa pafupifupi 3140 J/(kg·°C) (0.75 BTU/(lb·°F)), magawo atatu mwa anayi a madzi oyera, motero zimafunika kuchulukitsidwa kwa madzi m’chimodzimodzi- kufananiza dongosolo ndi madzi.

Kugwiritsa ntchito
| Itha kugwiritsidwa ntchito kwambiri muzodzola zopangira zopangira, utoto, utomoni wosinthanitsa ndi ion, mafuta, fungicides, zowonjezera zopanda cyanide, zopangira zikopa ndi zikopa, othandizira ochiritsa a epoxy resin, zofunikira zatsiku ndi tsiku, zothandizira thovu la polyurethane ndi zina. pa |
Kusakaniza kwa ethylene glycol ndi madzi kumapereka ubwino wowonjezera ku njira zoziziritsira komanso zoletsa kuzizira, monga kupewa dzimbiri ndi kuwonongeka kwa asidi, komanso kulepheretsa kukula kwa tizilombo toyambitsa matenda ndi bowa. glycol imayang'ana, zosakaniza, zosakaniza, kapena zothetsera.
M'makampani apulasitiki, ethylene glycol ndi kalambulabwalo wofunikira wa ulusi wa polyester ndi utomoni. Polyethylene terephthalate, yomwe imagwiritsidwa ntchito popanga mabotolo apulasitiki a zakumwa zoziziritsa kukhosi, imakonzedwa kuchokera ku ethylene glycol.
Ubwino
Ubwino wazinthu, kuchuluka kokwanira, kuperekera kogwira mtima, ntchito yabwino kwambiri Imakhala ndi mwayi wopitilira amine wofanana, ethanolamine, chifukwa kuchuluka kwakukulu kungagwiritsidwe ntchito pakuwonongeka komweko. Izi zimathandiza oyenga kutsuka hydrogen sulfide pamlingo wocheperako wozungulira wa amine osagwiritsa ntchito mphamvu zonse.
