Hydroxyethyl cellulose (HEC)

Hydroxyethyl cellulose(HEC) waa polymer aan-ionic ahayn, biyo-milmi kara oo ka yimid cellulose, polymer si dabiici ah u dhaca oo laga helo gidaarada unugyada dhirta.HEC waxaa lagu soo saaraa wax ka beddelka kiimikaad ee cellulose iyada oo la soo bandhigayo kooxaha hydroxyethyl qaab-dhismeedka cellulose.

HEC waxaa si weyn loogu isticmaalaa warshado kala duwan sababtoo ah sifooyinkeeda gaarka ah, oo ay ku jiraan awoodda ay u leedahay in ay dhumucdo, xirto, xasiliso, oo wax ka beddesho sifooyinka rheological ee xalalka aqueous.Qaar ka mid ah sifooyinka muhiimka ah iyo codsiyada HEC waxaa ka mid ah:

1. Wakiilka dhumucda: HEC waxaa caadi ahaan loo isticmaalaa sida wakiilka dhumuc ee tiro balaadhan oo ah alaabo, oo ay ku jiraan rinji, dahaarka, koollada, alaabta daryeelka shakhsi ahaaneed, iyo daawooyinka daawooyinka.Waxay ka caawisaa in la kordhiyo viscosity of xal aqueous, hagaajinaysaa ay joogto ah iyo hantida socodka.
2. Beddelaha Rheology: HEC waxay u shaqeysaa sidii wax ka beddelka rheology, taasoo la micno ah inay xakameyn karto habdhaqanka socodka iyo viscosity ee dareeraha.Rinjiyada iyo dahaarka, tusaale ahaan, HEC waxay ka caawisaa ka hortagga hoos u dhaca ama dareeraha inta lagu jiro codsiga waxayna wanaajisaa shaqada guud ee alaabta.
3. Xasijiye: HEC waxay u shaqeysaa sidii xasiliye, iyadoo gacan ka geysaneysa ilaalinta xasilloonida iyo isku-duubnaanta qaab-dhismeedka waqti ka dib.Waxay ka hortagi kartaa qallafsanaanta, kala-soocidda wajiga, ama noocyada kale ee xasilooni-darrada ee ka-hakinta iyo emulsions.
4. Filim hore: HEC waxay leedahay sifooyin samaynta filimada, taas oo u oggolaanaysa inay abuurto filimo khafiif ah, dabacsan marka qallalan.Gurigan waxaa loo isticmaalaa codsiyo kala duwan sida dahaarka, xabagta, iyo alaabta daryeelka shakhsi ahaaneed, halkaas oo HEC ay hagaajin karto adhesion filimka, daacadnimada, iyo guryaha xannibaadda.
5. Wakiilka Ku-xidhka: Qaababka dawooyinka, HEC waxa loo isticmaalaa xidhe ahaan si loo hagaajiyo isku xidhnaanta iyo isku-buufinta hababka kiniinka.Waxay ka caawisaa isku xidhka maaddooyinka firfircoon, iyada oo hubinaysa isku-duubnaanta iyo daacadnimada kaniiniyada.
6. Alaabooyinka Daryeelka Shakhsi ahaaneed: HEC waxaa caadi ahaan laga helaa alaabta daryeelka shakhsi ahaaneed sida shaambooyinka, qaboojiyaha, loshinka, kiriimyada, iyo jelka.Waxay u shaqeysaa sidii dhumuc weyn, xasiliye, iyo emulsifier, taasoo kor u qaadeysa qaab-dhismeedka, joogteynta, iyo waxqabadka alaabtan.

Guud ahaan, Hydroxyethyl cellulose (HEC) waa polymer-ka badan oo leh codsiyo ballaaran oo warshado kala duwan ah.Astaanteeda ayaa ka dhigaysa mid qiimo leh si kor loogu qaado waxqabadka, xasiloonida, iyo tayada bilicda alaabada lagu isticmaalo.
