I-Hydroxyethyl cellulose (HEC) yi-cellulose emhlophe okanye ekhaphukhaphu, engenavumba, engeyotyhefu okanye eqinile, elungiswa yi-etherification reaction ye-alkaline cellulose kunye ne-ethylene oxide (okanye i-chlorohydrin).I-Nonionic e-soluble cellulose ethers.Ekubeni i-HEC ineempawu ezintle zokuqina, ukumisa, ukusabalalisa, i-emulsifying, i-bonding, ifilimu-ifom, ukukhusela umswakama kunye nokubonelela nge-colloid ekhuselayo, isetyenziswe ngokubanzi ekuhlolisweni kweoli, ukugubungela, ukwakhiwa, amayeza, ukutya, i-textile, i-papermaking kunye ne-polymerization. kunye neminye imimandla.I-40 ye-mesh sieving rate ≥ 99%;
Imbonakalo: Ifibrous emhlophe ukuya kokukhanya emthubi okanye engumgubo eqinileyo, ayinatyhefu, ayinancasa, iyanyibilika emanzini.Ukunganyibiliki kwizinyibilikisi eziqhelekileyo eziphilayo.
I-viscosity itshintsha kancinci kuluhlu lwexabiso le-PH 2-12, kodwa i-viscosity iyancipha ngaphaya kolu luhlu.Ineempawu zokuqina, ukumisa, ukubopha, i-emulsifying, ukusabalalisa, ukugcina umswakama kunye nokukhusela i-colloid.Izisombululo kwiindidi ezahlukeneyo ze-viscosity zinokulungiswa.Ukungazinzi phantsi kobushushu obuqhelekileyo kunye noxinzelelo, kuthintele ukufuma, ubushushu, kunye nobushushu obuphezulu, kwaye ube nokunyibilika kakuhle kwetyuwa kwi-dielectrics, kwaye isisombululo sayo samanzi sivumela ukugcwala okuphezulu kweetyuwa ukuba kuhlale kuzinzile.
Iimpawu ezibalulekileyo:
Njenge-non-ionic surfactant, i-hydroxyethyl cellulose inezi mpawu zilandelayo ukongeza ekujikeni, ukuxhoma, ukubopha, ukudada, ukwenza ifilimu, ukusasaza, ukugcinwa kwamanzi kunye nokubonelela nge-colloid ekhuselayo:
1. I-HEC iyancibilika emanzini atshisayo okanye kumanzi abandayo, kwaye ayigqithisi kwiqondo lokushisa eliphezulu okanye ukubilisa, ukwenzela ukuba inoluhlu olubanzi lwe-solubility kunye neempawu ze-viscosity, kunye ne-gelation engeyona i-thermal;
2. Ayina-ionic kwaye inokuhlalisana kunye noluhlu olubanzi lwezinye iipolymers ezinyibilikayo zamanzi, i-surfactants, kunye neetyuwa.Yinto egqwesileyo ye-colloidal thickener yezisombululo eziphezulu ze-electrolyte;
3. Umthamo wokugcinwa kwamanzi uphindwe kabini kunalowo we-methyl cellulose, kwaye unolawulo olungcono lokuhamba.
4. Xa kuthelekiswa ne-methyl cellulose eyaziwayo kunye ne-hydroxypropyl methyl cellulose, ikhono lokusabalalisa i-HEC libi kakhulu, kodwa ikhono lokukhusela i-colloid linamandla.
