Yonke into omawuyazi malunga neHydroxy Ethyl Cellulose (HEC)

I-Hydroxyethyl cellulose (HEC) i-polymer e-soluble yamanzi ephuma kwi-cellulose, i-polymer yendalo efumaneka kwiindonga zeeseli zezityalo. I-HEC isetyenziswa ngokubanzi kumashishini ahlukeneyo ngenxa yeempawu zayo ezizodwa kunye nokusetyenziswa okuguquguqukayo. Nantsi yonke into ekufuneka uyazi malunga ne-HEC:

Iipropati ze-HEC:

1. Ukunyibilika kwamanzi: I-HEC inyibilika kakhulu emanzini, yenza izisombululo ezicacileyo kunye ne-viscous phezu koluhlu olubanzi lokugxila. Le propati yenza kube lula ukubandakanya kwi-formulation yamanzi kunye nokulungelelanisa i-viscosity.
2. Ukuqina: I-HEC yi-agent esebenzayo yokuqina, ekwazi ukunyusa i-viscosity yezisombululo ezinamanzi kunye nokumiswa. Inika i-pseudoplastic okanye i-shear-thinning behavior, oku kuthetha ukuba i-viscosity yayo iyancipha phantsi koxinzelelo lokucheba kwaye iphinde ibuyele xa uxinzelelo lususiwe.
3. Ukwenziwa kweFilimu: I-HEC inokwenza iifilimu eziguquguqukayo kunye nezidibeneyo xa zomisiwe, zenze ukuba zilungele izicelo ezifana neengubo, iipeyinti, kunye ne-adhesives. Iimpawu zokwenza ifilimu ye-HEC igalelo ekuphuculeni ukubambelela, ukuxhathisa umswakama, kunye nokukhuselwa komhlaba.
4. Ukuzinza: I-HEC ibonisa ukuzinza okulungileyo kuluhlu olubanzi lwamanqanaba e-pH, amaqondo okushisa, kunye neemeko zokucheba. Ichasene nokuthotywa kwe-microbial kwaye igcina ukusebenza kwayo kwiinkqubo ezahlukeneyo zoshishino kunye nokuqulunqwa.
5. Ukuhambelana: I-HEC iyahambelana noluhlu olubanzi lwezinye izongezo kunye nezithako ezisetyenziswa ngokuqhelekileyo kwimiqulu yemizi-mveliso, kubandakanywa i-surfactants, i-thickeners, i-polymers, kunye ne-preservatives. Inokufakwa ngokulula kwiinkqubo zamacandelo amaninzi ukufikelela kwiimpawu zokusebenza ezifunwayo.

Usetyenziso lwe-HEC:

1. Iipeyinti kunye neeNgxoxo: I-HEC isetyenziswe njenge-rheology modifier kunye ne-thickener kwiipeyinti ezisekelwe emanzini, iingubo kunye ne-primers. Inceda ukuphucula ulawulo lwe-viscosity, ukulinganisa, ukuxhathisa i-sag, kunye nokwakheka kwefilimu, okukhokelela ekugqityweni okugudileyo kunye nokufana okufanayo.
2. I-Adhesives kunye ne-Sealants: I-HEC iqeshwe njenge-ejenti yokuqina kunye nokubopha kwi-adhesives esekelwe emanzini, i-sealants, kunye ne-caulks. Iphucula i-tackiness, i-adhesion, kunye neempawu zokuhamba, ukuphucula ukusebenza kunye nokusebenza kwezi mveliso.
3. IiMveliso zoNyango loMntu: I-HEC isetyenziswa ngokubanzi ekuqulunqweni kokunyamekela komntu kunye neemveliso zokuthambisa, kubandakanywa i-shampoos, i-conditioner, i-lotions, i-creams, kunye ne-gel. Isebenza njenge-thickener, i-stabilizer, kunye ne-agent-forming agent, inikezela ukuthungwa okunqwenelekayo, i-viscosity, kunye neempawu zokuziva.
4. Izinto zokwakha: I-HEC ifakwe kwizinto zokwakha ezifana ne-samente-based mortars, i-grouts, kunye ne-adhesives ye-tile ukuphucula ukusebenza, ukugcinwa kwamanzi, kunye namandla okudibanisa. Iphucula ukusebenza kunye nokuqina kwezi zinto kwizicelo ezahlukeneyo zokwakha.
5. I-Pharmaceuticals: Kwishishini lamachiza, i-HEC isetyenziswa njenge-binder, i-disintegrant, kunye ne-agent-release-release-release agent ekuqulunqweni kwethebhulethi. Inceda ukuphucula i-tablet cohesion, ukuchithwa, kunye neeprofayili zokukhutshwa kweziyobisi, ezinegalelo ekusebenzeni kunye nokuzinza kweefom zedosi yomlomo.
6. Ishishini le-Oli neGesi: I-HEC isetyenziselwa ukugrumba ulwelo kunye nolwelo olugqityiweyo njenge-viscosifier kunye nearhente yokulawula ukulahleka kolwelo. Inceda ukugcina uzinzo lwe-wellbore, ukumisa izinto eziqinileyo, kunye nokulawula i-rheology yolwelo kwimisebenzi yokomba.
7. Ukutya kunye neSiselo: I-HEC ivunyiwe ukuba isetyenziswe njengesongezo sokutya kunye ne-ejenti yokuqina kwiindidi zokutya kunye neemveliso zesiselo, kubandakanywa iisosi, izambatho, iimveliso zobisi kunye neziselo. Inika ukuthungwa, i-viscosity, kunye nokuzinza ngaphandle kokuchaphazela incasa okanye ivumba.

I-Hydroxyethyl cellulose (HEC) yipolymer eguquguqukayo kwaye isetyenziswa ngokubanzi kunye nezicelo kuwo wonke amashishini amaninzi. Iimpawu zayo ezikhethekileyo, kubandakanywa ukunyibilika kwamanzi, ukuqina, ukwenza ifilimu, ukuzinza, kunye nokuhambelana, kwenza kube yinto ebalulekileyo kwiindlela ezininzi kunye neemveliso.
