I-Hydroxyethyl cellulose kunye ne-ethyl cellulose

I-Hydroxyethyl cellulose kunye ne-ethyl cellulose zizinto ezimbini ezahlukeneyo. Baneempawu ezilandelayo.

Iselulosi yeHydroxyethyl

Njenge-surfactant engeyiyo i-ionic, ngaphezu kokuqina, ukuxhoma, ukubopha, ukujikeleza, ukwenza ifilimu, ukusabalalisa, ukugcina amanzi kunye nokubonelela nge-colloids yokukhusela, nayo ineempawu ezilandelayo:

1. I-HEC iyancibilika kumanzi ashushu okanye abandayo, kwaye ayigqithisi kwiqondo lokushisa eliphezulu okanye ukubilisa, ukwenzela ukuba inoluhlu olubanzi lwe-solubility kunye neempawu ze-viscosity, kunye ne-gelation engeyiyo i-thermal;

2. I-non-ionic ngokwayo inokuhlalisana kunye nolunye uluhlu olubanzi lwezinye iipolymers ezinamanzi, i-surfactants kunye neetyuwa, kwaye i-colloidal thickener egqwesileyo equlethe izisombululo 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 i-colloid ekhuselayo inamandla amakhulu.

Ethyl cellulose

Yi-ether engeyo-ionic cellulose enganyibilikiyo emanzini kodwa inyibilika kwizinyibilikisi zendalo. Inezi mpawu zilandelayo:

1. Akukho lula ukutshisa.

2. Ukuzinza kakuhle kwe-thermal kunye ne-thermoplasticity egqwesileyo.

3. Akukho mbala kukukhanya kwelanga.

4. Ukuguquguquka okuhle.

5. Iimpawu ezilungileyo ze-dielectric.

6. Inokumelana ne-alkali egqwesileyo kunye nokuxhatshazwa kwe-asidi ebuthakathaka.

7. Ukusebenza kakuhle kokuchasana nokuguga.

8. Ukumelana kakuhle netyuwa, ukubanda kunye nokufunxa ukufuma.

9. Uzinzile kwiikhemikhali, ukugcinwa kwexesha elide ngaphandle kokuwohloka.

10. Iyahambelana neerasi ezininzi kunye nokuhambelana kakuhle nazo zonke iiplastiki.

11. Kulula ukutshintsha umbala phantsi kommandla oqinileyo we-alkaline kunye neemeko zokushisa.
