Kodi Kukhuthala kwa Madzi a Glycol ndi Chiyani?
Kukhuthala kwa zosakaniza za glycol-madzi kumasiyana kwambiri kutengera mtundu wa glycol (monga,ethylene or propylene), kuchuluka kwake, ndi kutentha kwake. Propylene glycol, yomwe imakonda kugwiritsidwa ntchito pochepetsa poizoni, imasonyeza kusintha kofanana kwa kukhuthala koma ili ndi zotsatira zapadera za kukakamira kwa pamwamba, zomwe zimapangitsa kuti zikhale zovuta.

Ubwino wa Kuzindikira Kukhuthala
Mu kayendedwe ka mapaipi okhala ndi kutentha kochepa kwa petrochemical, monga mpweya wa pansi pa nyanja kapena mizere yamafuta, zosakaniza zamadzi-glycol zimagwiritsidwa ntchito ngati madzi amadzimadzi osapsa ndi moto a machitidwe owongolera monga ma valve ndi ma actuator. Kutentha kotsika (monga, pafupifupi 2°C m'nyanja yakuya) kumawonjezera kukhuthala, kupangitsa kuyenda ndi mafuta kukhala kovuta, pomwe kupsinjika kwakukulu (mpaka 110 MPa) kumatha kuthana ndi izi chifukwa cha zosakaniza zokhala ndi madzi ambiri (>75%), kuchepetsa kukhuthala ndikuthandizira magwiridwe antchito. Kuyeza kukhuthala kumalola ogwiritsa ntchito kulosera ndikuchepetsa zotsatirazi, kuonetsetsa kuti magwiridwe antchito nthawi zonse popanda kugwiritsa ntchito mphamvu zambiri kapena kuwonongeka kwa makina.
