Yenziwa ngantoni i-hydroxyethyl cellulose?

I-Hydroxyethyl cellulose (HEC) yipolima yokwenziwa ephuma kwi-cellulose, i-polysaccharide eyenzeka ngokwemvelo efumaneka kwizityalo.Ingumgubo omhlophe, onyibilikayo wamanzi osetyenziswa njenge-ejenti yokuqina, ukumisa, kunye nokuzinzisa kwiimveliso ezahlukeneyo, kubandakanya izinto zokuthambisa, amayeza, izicoci kunye neemveliso zokutya.

I-HEC iveliswa ngokuphendula i-cellulose nge-ethylene oxide, i-chemical compound ephuma kwi-ethylene, i-hydrocarbon gas.I-ethylene oxide isabela kunye namaqela e-hydroxyl kwiimolekyuli ze-cellulose, zenza unxibelelwano lwe-ether phakathi kwee-molecule ze-cellulose.Le ndlela yokusabela idala ipholima enobunzima obuphezulu bemolekyuli kuneselulosi yoqobo, kwaye inika ipholima iipropathi zayo ezinyibilikayo emanzini.

I-HEC isetyenziswa kwiimveliso ezahlukeneyo, kubandakanywa izithambiso, amayeza, izinto zokucoca, kunye neemveliso zokutya.Kwizinto zokuthambisa, isetyenziswa njenge-ejenti yokuqina, i-agent yokumisa, kunye ne-stabilizer.Kumachiza, isetyenziswa njenge-binder, i-disintegrant, kunye ne-arhente yokumisa.Kwi-detergents, isetyenziswa njenge-agent e-thickening, i-agent yokumisa, kunye ne-stabilizer.Kwiimveliso zokutya, isetyenziswa njenge-ejenti yokuqina, i-agent yokumisa, kunye ne-stabilizer.

I-HEC iphinda isetyenziswe kwimisebenzi yokugaya ioli kunye negesi, apho isetyenziselwa ukwandisa i-viscosity ye-drilling fluids kunye nokunciphisa ukulahlekelwa kwamanzi ekubunjweni.Ikwasetyenziselwa ukwenza iphepha, apho isetyenziselwa ukwandisa amandla kunye nokuqina kwephepha.

I-HEC yinto engeyiyo ityhefu, i-non-irritation, kunye ne-non-allergenic, eyenza ikhuseleke ukusetyenziswa kwiimveliso ezahlukeneyo.Iyakwazi ukubola, nto leyo eyenza ukuba ibe lukhetho oluhambelana nokusingqongileyo.
