Isticmaalka hydroxyethyl cellulose

Sida surfactant aan-ionic ahayn, hydroxyethyl cellulose waxay leedahay sifooyinka soo socda marka lagu daro shaqooyinka joojinta, dhumucda, kala firdhinta, sabaynta, isku xidhka, samaynta filimada, haynta biyaha iyo bixinta kolloid ilaalin ah:

1. HEC waxay ku milmaysaa biyo kulul ama biyo qabow, oo kuma soo da'aan heerkulka sare ama karkarinta, si ay u leedahay noocyo kala duwan oo milmayn iyo sifooyin viscosity, iyo gelation non-thermal;

2. Marka la barbar dhigo methyl cellulose ee la aqoonsan yahay iyo hydroxypropyl methyl cellulose, awoodda kala firdhisan ee HEC waa tan ugu xun, laakiin awoodda kolloid ilaalinta ayaa ah kan ugu xooggan.

3. Awoodda haynta biyuhu waxay laban laab ka badan tahay tan methyl cellulose, waxayna leedahay nidaaminta qulqulka wanaagsan.

Ka taxaddar marka la isticmaalayo:

Maaddaama dusha lagu daaweeyay hydroxyethyl cellulose ay tahay budo ama cellulose adag, way fududahay in la xakameeyo oo lagu milmo biyaha ilaa inta waxyaabaha soo socda la siinayo.

1. Kahor iyo ka dib marka lagu daro hydroxyethyl cellulose, waa in si joogto ah loo walaaqaa ilaa xalku si buuxda u hufan yahay oo cad yahay.

2. Waa in si tartiib ah loogu shaandheeyaa haanta isku dhafka ah, si toos ah ha ugu darin xaddi badan oo ah hydroxyethyl cellulose oo samaystay buro ama kubbado haanta isku dhafka ah.

3. Heerkulka biyaha iyo qiimaha PH ee biyaha ayaa xiriir muuqda la leh kala dirida cellulose hydroxyethyl, markaa waa in fiiro gaar ah la bixiyaa.

4. Ha ku darin qaar ka mid ah walxaha alkaline isku darka ka hor inta aan la diirin budada hydroxyethyl cellulose biyo.Kor u qaadista qiimaha PH ka dib kululaynta waxay kaa caawin doontaa milanka.

HEC waxay isticmaashaa:

1. Waxaa guud ahaan loo isticmaalaa sida dhumuc weyn, wakiilka ilaalinta, koollada, stabilizer, iyo lagu daro diyaarinta emulsions, jellies, boomaatada, looshannada, nadiifinta indhaha, suppositories iyo kiniiniyada, iyo sidoo kale loo isticmaalo sida jel hydrophilic iyo Qalfoofka Materials. diyaarinta diyaarinta sii-deynta joogtada ah ee nooca-matrix-ka ah, waxaana sidoo kale loo isticmaali karaa xasiliye cuntada.

2. Loo isticmaalo sidii wakiilka cabbirka ee warshadaha dunta, iyo sidii wakiil caawiye ee isku xidhka, dhumucda, emulsifying, iyo xasilinta qaybaha warshadaha elegtarooniga ah iyo iftiinka.

3. Waxa loo istcimaalaa dhumucdiye iyo luminta dareeraha dareeraha qodista biyaha ku salaysan iyo dareeraha dhamaystirka, saamaynta dhumucduna waxay ku caddahay dareeraha qodista brine.Waxa kale oo loo isticmaali karaa dhimis luminta dareeraha sibidhka ceelka saliidda.Waxa lagu xidhi karaa ion bir polyvalent si loo sameeyo jel.

4. Alaabtan waxaa loo isticmaalaa sida kala-saarid loogu talagalay polymerization of petroleum biyaha ku salaysan jel jebinta dareere, polystyrene iyo polyvinyl chloride, iwm by jabay.Waxa kale oo loo isticmaali karaa sidii dhumucda emulsion ee warshadaha rinjiga, hygrostat ee warshadaha elektiroonigga ah, xinjirowga lidka ku ah sibidhka iyo wakiilka qoyaanka ilaalinta ee warshadaha dhismaha.Dhaldhalaalka warshadaha dhoobada iyo dawada cadayga.Waxa kale oo si weyn loogu isticmaalaa daabacaadda iyo midabaynta, dunta, waraaqaha samaynta, daawada, nadaafadda, cuntada, sigaarka, sunta cayayaanka iyo walxaha dab-damiska.
