Hydroxy Ethyl Cellulose (HEC) - kukumba mafuta

Hydroxyethyl cellulose (HEC) ndi polima yosungunuka m'madzi yochokera ku cellulose, yomwe imagwiritsidwa ntchito kwambiri ngati rheology modifier ndi kuwongolera kutaya kwamadzi pobowola mafuta.

Pakubowola mafuta, madzi obowola amagwiritsidwa ntchito kupaka mafuta pobowola, kunyamula zodula zobowola pamwamba, ndikuwongolera kuthamanga kwachitsime. Madzi obowola amathandizanso kuti chitsimecho chikhazikike komanso kuteteza kuwonongeka kwa mapangidwe.

HEC imawonjezeredwa kumadzi obowola kuti awonjezere kukhuthala komanso kuwongolera kayendedwe ka madzi. Itha kuthandizira kuyimitsa zobowola ndikuletsa kukhazikika, komanso kupereka njira yabwino yothetsera kutayika kwamadzimadzi kuti chitsime chisungike bwino. HEC itha kugwiritsidwanso ntchito ngati mafuta opangira mafuta komanso chosinthira keke yosefera, kuti ipititse patsogolo magwiridwe antchito ndikubowola.

Ubwino umodzi wa HEC pakubowola mafuta ndikukhazikika kwake pakutentha kwambiri komanso kupanikizika kwambiri. HEC ikhoza kukhalabe ndi mawonekedwe ake a rheological ndi magwiridwe antchito amadzimadzi-kutaya mumitundu yosiyanasiyana ya kutentha ndi kupsinjika, ndikupangitsa kuti ikhale yoyenera kugwiritsidwa ntchito m'malo ovuta kubowola.

HEC imagwirizananso ndi zinthu zina zomwe zimagwiritsidwa ntchito pobowola madzi, monga dongo, ma polima, ndi mchere, ndipo zikhoza kuphatikizidwa mosavuta mu mapangidwe. Kuchepa kwake kawopsedwe komanso kuwonongeka kwachilengedwe kumapangitsa kuti ikhale yogwirizana ndi chilengedwe komanso yotetezeka kuti igwiritsidwe ntchito pobowola mafuta.

Ponseponse, HEC ndi polima yosunthika yomwe imatha kuwongolera bwino ma rheological ndikuwongolera kutayika kwamadzimadzi mumadzi obowola mafuta. Makhalidwe ake apadera komanso kuyanjana ndi zida zina zimapangitsa kukhala chisankho chodziwika bwino pakubowola m'malo osiyanasiyana.
