Hydroxyethyl cellulose (HEC) waa xarun si weyn loo isticmaalo oo leh codsiyo kala duwan oo ku saabsan warshadaha.Sidoo kale loo yaqaan hydroxyethylcellulose ama HEC, waxay ka tirsan tahay qoyska ethers cellulose, oo ka soo jeeda cellulose iyada oo loo marayo isbeddel kiimiko ah.Beddelkaani wuxuu ku lug leeyahay soo bandhigida kooxaha hydroxyethyl ee laf dhabarta cellulose, taas oo kor u qaadaysa milmaheeda iyo sifooyinka kale ee shaqada.Iyadoo hydroxyethyl cellulose uu yahay magaca caadiga ah, waxaa sidoo kale laga yaabaa in lagu tilmaamo magacyo kale oo ku jira xaalado kala duwan, taas oo ku xidhan codsigeeda iyo warshadaha gaarka ah ee ku lug leh.
Dhinaca kimisteriga iyo codsiyada warshadaha, hydroxyethyl cellulose waxaa laga yaabaa in loo yaqaan magaca kiimikada, ethyl hydroxyethyl cellulose ama si fudud hydroxyethylcellulose.Ganacsiga iyo baayacmushtarka, waxa laga yaabaa in ay raacdo magacyo summadeed ama calaamado ganacsi oo kala duwan, taas oo ku xidhan soo saaraha ama alaab-qeybiyaha.Magacyadan waxaa ka mid noqon kara Natrosol, Cellosize, Bermocoll, iyo kuwa kale, taas oo ku xidhan shirkadda soo saarta ama qaybinaysa alaabta.
Dhismaha iyo qalabka dhismaha, hydroxyethyl cellulose waxaa inta badan loo isticmaalaa sida wakiilka dhumuc, kaalmaynta biyaha, iyo wax ka beddelka rheology ee alaabta sibidhka ku salaysan, sida hoobiye, grouts, iyo dahaarka sibidhka.
Daawooyinka iyo alaabada daryeelka shakhsi ahaaneed, hydroxyethyl cellulose waxay u adeegtaa sidii walax isku dhafan oo leh codsiyada qaabaynta sida kiriimyada, kareemka, shaambooyinka, iyo xalalka indhaha.Warshadahan dhexdiisa, waxa laga yaabaa in lagu liis gareeyo calaamadaha alaabta iyada oo la adeegsanayo magaceeda kiimiko ama sida wakiilka dhumuc, xasiliye, ama wax ka beddelka viscosity.Magacyada kale waxaa ka mid noqon kara Natrosol, Cellosize, ama si fudud HEC, taas oo ku xidhan calaamadaynta ama heshiisyada calaamadaynta ee soo saaraha.
Warshadaha cuntada iyo cabitaanka, hydroxyethyl cellulose waxa loo isticmaalaa dhumucdiye, xasiliye, ama emulsifier ahaan alaabooyin kala duwan oo u dhexeeya suugada iyo dhaymada ilaa cabitaannada iyo jalaatada.Xaaladdan oo kale, waxaa loo tixraaci karaa si fudud sida HEC ama magacyadeeda summada haddii alaabooyin ganacsi oo gaar ah la isticmaalo.
halka hydroxyethyl cellulose uu yahay magaca kiimikada caadiga ah ee xaruntan, waxaa laga yaabaa in lagu yaqaan magacyo kala duwan oo ku xiran warshadaha, macnaha guud, iyo codsi gaar ah.Magacyadan beddelka ah waxaa ku jiri kara magacyo ganacsi, magacyo calaamad, ama sharraxaad guud oo ku saabsan shaqadeeda ama hantideeda.Iyadoo aan loo eegin magaca la isticmaalo, hydroxyethyl cellulose ayaa weli ah walxo qiimo leh oo la taaban karo oo leh codsiyo baahsan oo ku baahsan warshado badan.
