Zotsatira za Kutentha pa Hydroxy Ethyl Cellulose Solution

Hydroxy Ethyl Cellulose (HEC) ndi polima wosungunuka m'madzi womwe umagwiritsidwa ntchito kwambiri m'mafakitale osiyanasiyana monga zodzoladzola, mankhwala, ndi chakudya monga thickener, binder, ndi stabilizer. Kukhuthala kwa mayankho a HEC kumadalira kwambiri kutentha, ndipo kusintha kwa kutentha kungakhudze thupi la yankho.

Pamene kutentha kwa yankho la HEC kukuwonjezeka, kukhuthala kwa yankho kumachepa chifukwa cha kuchepa kwa mgwirizano wa haidrojeni pakati pa maunyolo a polima. Kutsika kwa viscosity kumeneku kumawonekera kwambiri pa kutentha kwakukulu ndipo kumapangitsa kuti pakhale njira yochepetsera, yamadzimadzi.

Mosiyana ndi zimenezo, pamene kutentha kwa njira ya HEC kumachepetsedwa, kukhuthala kwa yankho kumawonjezeka chifukwa cha kuwonjezeka kwa hydrogen pakati pa maunyolo a polima. Kuwonjezeka kwa viscosity kumeneku kumawonekera kwambiri pa kutentha kochepa ndipo kumapangitsa kuti pakhale njira yowonjezera, yowonjezera ngati gel.

Kuonjezera apo, kusintha kwa kutentha kungakhudzenso kusungunuka kwa HEC m'madzi. Pa kutentha kwambiri, HEC imakhala yosungunuka kwambiri m'madzi, pamene kutentha kochepa, HEC imakhala yochepa kwambiri m'madzi.

Ponseponse, zotsatira za kutentha pa yankho la HEC zimadalira kuchuluka kwa polima, chikhalidwe cha zosungunulira, ndi ntchito yeniyeni ya yankho la HEC.
