Kodi hydroxyethylcellulose ndi yomamatira?

Hydroxyethyl cellulose (HEC)ndi polima yomwe imagwiritsidwa ntchito kwambiri m'mafakitale osiyanasiyana, kuphatikiza mankhwala, zodzoladzola, ndi zakudya. Makhalidwe ake amatha kusiyanasiyana malinga ndi zinthu monga ndende, kulemera kwa maselo, komanso kupezeka kwa zinthu zina. Ngakhale HEC palokha si yomata mwachilengedwe, kuthekera kwake kupanga ma gels kapena mayankho kumatha kupangitsa kuti ikhale yolimba pansi pazifukwa zina.

HEC ndi polima yosungunuka m'madzi yopanda ion yochokera ku cellulose. Ntchito yake yayikulu ndi monga chowonjezera, chokhazikika, kapena choyambirira cha filimu muzinthu kuyambira pazinthu zosamalira anthu monga ma shampoos ndi mafuta odzola mpaka kupanga mankhwala ndi zakudya. Mapangidwe ake a mamolekyu amathandizira kuti azilumikizana ndi mamolekyu amadzi, kupanga ma hydrogen bond ndikupanga mayankho a viscous kapena gels.

Kukakamira kwa zinthu zomwe zili ndi HEC kumatha kutengera zinthu zingapo:

Kuyikira Kwambiri: Kuchulukira kwa HEC pamapangidwe kungayambitse kukhuthala kowonjezereka komanso mawonekedwe omata. Opanga amasinthitsa mosamala kuchuluka kwa HEC kuti akwaniritse kusasinthika komwe kumafunikira popanda kupanga chinthucho kumata mopambanitsa.
Kuyanjana ndi zinthu zina:HECakhoza kugwirizana ndi zigawo zina mu chiphunzitso, monga surfactants kapena mchere, amene angasinthe rheological katundu. Kutengera kapangidwe kake, kuyanjana kumeneku kungapangitse kumamatira.
Zinthu zachilengedwe: Zinthu monga kutentha ndi chinyezi zingakhudze khalidwe la mankhwala okhala ndi HEC. M'malo achinyezi, mwachitsanzo, ma gels a HEC amatha kusunga chinyezi chochulukirapo kuchokera mumlengalenga, zomwe zitha kukulitsa kumamatira.
Njira yogwiritsira ntchito: Njira yogwiritsira ntchito imathanso kukhudza malingaliro a kukakamira. Mwachitsanzo, chinthu chomwe chili ndi HEC chimatha kumva ngati chomata kwambiri chikagwiritsidwa ntchito mofanana, koma ngati chowonjezera chikasiyidwa pakhungu kapena tsitsi, chingamve ngati chovuta.
Kulemera kwa mamolekyu: Kulemera kwa molekyulu ya HEC kumatha kukhudza kuthekera kwake kokulirakulira komanso kapangidwe kake komaliza. Kulemera kwa molekyulu ya HEC kungapangitse mayankho ochulukirapo, omwe angapangitse kumamatira.
Muzodzoladzola zodzikongoletsera, HEC nthawi zambiri imagwiritsidwa ntchito popereka mawonekedwe osalala, okoma ku mafuta odzola ndi zopaka popanda kusiya zotsalira zomata. Komabe, ngati sizinapangidwe bwino kapena kugwiritsidwa ntchito, zinthu zomwe zili ndi HEC zimatha kumva ngati zomata kapena zomata pakhungu kapena tsitsi.

pamenehydroxyethyl celluloseLokha silimamamatira mwachibadwa, kugwiritsidwa ntchito kwake popanga mapangidwe kungapangitse mankhwala okhala ndi milingo yosiyanasiyana yamakakamira malingana ndi mapangidwe ake ndi njira zogwiritsira ntchito. Opanga amalinganiza mosamala zinthu izi kuti akwaniritse kapangidwe kake komanso magwiridwe antchito pomaliza.
