Zotsatira za kutentha pa hydroxy ethyl cellulose yankho

Khalidwe la hydroxyethyl cellulose (hec) mayankho limakhudzidwa ndi kusintha kwa kutentha. Nazi zina mwa kutentha pa mayankho a HeC:

1. Ma Isccess: Makutu a mayankho a HeC nthawi zambiri amachepetsa monga kutentha kumawonjezeka. Izi zimachitika chifukwa chochepetsa kulumikizana pakati pa hec mamolekyulu pabwino, kumapangitsa kuti mamasukidwe. Mosiyana, mafakisoni amachulukana ngati kutentha kumachepa chifukwa njira zosinthira zachipole zimakhazikika.
2. Kusungunuka: Hec amasungunuka m'madzi pamitundu yosiyanasiyana. Komabe, kuchuluka kwa kusungunuka kungasinthe ndi kutentha, chifukwa kutentha kwambiri kumalimbikitsa kusungunuka mwachangu. Kutentha kochepa kwambiri, ma hec amatha kukhala owoneka ngati owoneka bwino kapena a gel, makamaka makamaka pamtunda wapamwamba.
3. Geut: Mayankho a hec amatha kupatuka kwambiri pamatenthedwe otsika, ndikupanga mawonekedwe a gel osakaniza chifukwa cha kuchuluka kwa ma testal. Khalidwe lalikululi limasinthidwa ndipo limatha kuwonedwa mu zothetsera za hec, makamaka kutentha pansi pa mikangano.
4. Kukhazikika kwa matenthedwe: hec yankho la chiwonetsero bwino kwambiri kutentha kwa kutentha kwamitundu yambiri. Komabe, kutentha kwambiri kumatha kubweretsa kuwonongeka kwa unyolo wa polymer, zomwe zimapangitsa kuchepa kwa mafayilo ndi kusintha m'njira. Ndikofunikira kuti mupewe kuwonekera kwa nthawi yayitali kuti musunge yankho.
5. Kupatukana kwa gawo: Kusintha kwa kutentha kumatha kukulitsa gawo la njira ya hec, makamaka pamatenthedwe oyandikira malire. Izi zitha kuchititsa mapangidwe a magawo awiri a magawo awiri, ndi hec yodziyesa yothetsera kutentha pang'ono kapena m'matumbidwe ake.
6. Mphamvu: Khalidwe la HHEOAGOLOAGOLO la HeC ndi kutentha komwe kumadalira. Kusintha kwa kutentha kumatha kukhudza kakhalidwe kameneka, kugwedeza kupatulira, ndi thixotroptic njira ya hec, kumapangitsa kuti ntchito yawo ndi machitidwe awo.
7. Zotsatira pazokhudza kugwiritsa ntchito: Kusinthasintha kwa kutentha kumatha kusintha magwiridwe antchito a HeC mu ntchito zosiyanasiyana. Mwachitsanzo. M'mapangidwe opanga mankhwala, makulidwe otentha amatha kusintha mankhwala kumasula kinetics ndi Mlingo wa Mlingo.

temperature plays a significant role in the behavior of hydroxyethyl cellulose (HEC) solutions, affecting viscosity, solubility, gelation, phase behavior, rheological properties, and application performance. Kuzindikira izi ndikofunikira kuti mutseke mapangidwe a Hec m'malo osiyanasiyana.
