Hydroxyethyl cellulose waa polymer aan-ionic-biyo-milmi leh oo laga sameeyay cellulose, maaddo polymer dabiici ah, iyada oo loo marayo taxane kiimiko ah. Waa walax adag oo budo ah oo cad ama huruud ah, aan ur iyo dhadhamin lahayn, taas oo lagu milmi karo biyaha qabow iyo biyaha kulul labadaba, heerka kala diriddu wuxuu kordhiyaa kororka heerkulka. Guud ahaan, waa mid aan lagu milmi karin inta badan dareerayaasha organic. Waxa loo isticmaalaa sidii dhumuc iyo xasiliye rinjiga cinjirka ah. Way fududahay in lagu kala firdhiyo biyo qabow oo leh pH oo ka yar ama la mid ah 7, laakiin way fududahay in lagu daro dareeraha alkaline, sidaas darteed guud ahaan horay ayaa loogu sii diyaariyay isticmaalka dambe, ama biyaha acid daciifka ah ama xal organic ayaa laga sameeyaa slurry. , iyo waxa kale oo lagu qasi karaa granular kale Maaddooyinka waa engegan oo la isku daray.
Astaamaha hydroxyethyl cellulose:
HEC waxay ku milmi kartaa biyo kulul ama qabow, oo kuma soo da'in heerkulka sare ama karkarinta, taas oo ka dhigaysa inay leedahay noocyo kala duwan oo milmayn iyo sifooyin viscosity ah, iyo gelation aan kulayl ahayn.
Waxay la noolaan kartaa tiro balaadhan oo ah polymers kale oo biyaha ku milma, surfactants, iyo cusbada, waana dhumuc weyn oo kolloidal ah oo loogu talagalay xalalka ka kooban elektrolytka-fiirsashada sare.
Awoodda haysashada biyuhu waxay laban laab ka badan tahay tan methyl cellulose, waxayna leedahay nidaaminta qulqulka wanaagsan.
Marka la barbar dhigo methyl cellulose-ka la aqoonsan yahay iyo hydroxypropyl methyl cellulose, awoodda kala firdhinta ee HEC waa tan ugu xun, laakiin awoodda kolloid ee ilaalinta ayaa ah tan ugu xooggan.
Dhisme aad u wanaagsan; waxay leedahay faa'iidooyinka shaqada-badbaadinta, ma fududa in lagu tixo, anti-sag, anti-splash wanaagsan, iwm.
Waafaqid wanaagsan oo leh qalabyo kala duwan oo dusha sare ah iyo waxyaalaha lagu ilaaliyo ee loo isticmaalo rinjiga cinjirka.
Viscosity kaydinta waa mid deggan, taas oo ka hortagi karta guud ahaan hydroxyethyl cellulose si ay u yareeyaan viscosity ee rinjiga cinjirka inta lagu guda jiro kaydinta ay sabab u tahay kala go'a ee enzymes.
