Hydroxyethyl cellulose (HEC) ndi polima wosungunuka m'madzi yemwe amagwiritsidwa ntchito kwambiri pazinthu zosiyanasiyana monga zomatira, zokutira, ndi zinthu zosamalira anthu.Kusungunula HEC m'madzi ndi njira yosavuta yomwe ingakwaniritsidwe pogwiritsa ntchito njira zotsatirazi:
Sankhani giredi yoyenera ya HEC: HEC imapezeka m'makalasi osiyanasiyana okhala ndi masikelo osiyanasiyana a ma molekyulu ndi magawo olowa m'malo.Kusankhidwa kwa kalasi kudzadalira ntchito yeniyeni ndi katundu wofunidwa wa mankhwala omaliza.
Konzani madzi: Chinthu choyamba ndikukonzekera madzi poyesa kuchuluka kwa madzi ofunikira ndikuwotha kutentha kwapakati pa 70-80 ° C.Kutenthetsa madzi kumathandizira kufulumizitsa kusungunuka ndikuonetsetsa kuti HEC imakhala ndi madzi okwanira.
Onjezani HEC kumadzi: Madzi akafika kutentha komwe mukufuna, pang'onopang'ono yonjezerani HEC m'madzi pamene mukugwedeza mosalekeza.Ndikofunika kuwonjezera HEC pang'onopang'ono komanso pang'onopang'ono kuti musagwedezeke ndikuonetsetsa kuti imabalalika m'madzi.
Pitirizani kuyambitsa: Mukawonjezera HEC m'madzi, pitirizani kuyambitsa kusakaniza kwa mphindi pafupifupi 30.Izi zidzathandiza kuonetsetsa kuti HEC yasungunuka kwathunthu ndi kuthiridwa madzi.
Lolani kuti chisakanizocho chizizizira: Pambuyo pa HEC itasungunuka kwathunthu, lolani kuti chisakanizocho chizizizira kutentha.Pamene kusakaniza kumazizira, kumakhuthala ndikufika ku viscosity yake yomaliza.
Sinthani pH ndi mamasukidwe akayendedwe: Malingana ndi ntchito yeniyeni, zingakhale zofunikira kusintha pH ndi kukhuthala kwa yankho la HEC.Izi zikhoza kuchitika powonjezera asidi kapena maziko kuti asinthe pH ndi kuwonjezera madzi kapena HEC yowonjezera kuti musinthe kukhuthala.
Kusungunula HEC m'madzi ndi njira yosavuta yomwe ingakwaniritsidwe ndi masitepe ochepa.Posankha kalasi yoyenera ya HEC, kukonzekera madzi bwino, ndikuyambitsa kusakaniza kosalekeza, n'zotheka kupeza njira yothetsera HEC yosungunuka yomwe ingagwiritsidwe ntchito m'njira zosiyanasiyana.
