Hydroxyethyl cellulose Thickener

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 kwi-oyile yokuhlola, iingubo, 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.

Iselulosi yeHydroxyethylujiya

I-viscosity iyatshintsha 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.

Kusetyenziswa kwanjaniI-HEC?

yongezwe ngokuthe ngqo ngexesha lemveliso

1. Yongeza amanzi acocekileyo kwibhakethi enkulu exhotyiswe ngomxube wokucheba ophezulu.

2. Qala ukuvuselela ngokuqhubekayo ngesantya esiphantsi kwaye usihluze ngokukhawuleza i-hydroxyethyl cellulose kwisisombululo ngokulinganayo.

3. Qhubeka uvuselela de onke amaqhekeza afakwe emanzini.

4. Emva koko yongeza i-agent ye-antifungal, izongezo ze-alkaline ezifana ne-pigments, i-dispersing aids, amanzi e-ammonia.

5. Gxuma de kube yonke i-cellulose ye-hydroxyethyl ichithwe ngokupheleleyo (i-viscosity yesisombululo iyanda kakhulu) ngaphambi kokuba ungeze ezinye izinto kwifomula, kwaye ugaye de kube yimveliso egqityiweyo.
