Hydroxyethyl cellulose waa dhexdhexaad ama heer viscosity heer sare ah ee ether cellulose, loo isticmaalo dhumuc weyn iyo xasilin ee daahan biyaha ku salaysan, gaar ahaan marka viscosity kaydinta sare iyo viscosity codsigu hooseeyo.Ether Cellulose waa sahlan tahay in lagu kala firdhiyo biyo qabow oo leh qiimaha pH ≤ 7, laakiin way fududahay in lagu daro dareeraha alkaline ee leh qiimaha pH ≥ 7.5, markaa waa inaan fiiro gaar ah u leenahay kala firdhinta etherka cellulose.
Tilmaamaha iyo isticmaalka hydroxyethyl cellulose:
1. Anti-enzyme non-ionic water dhumucdiisuna, kaas oo loo isticmaali karo tiro balaadhan oo ah qiimaha pH (PH=2-12).
2. Si fudud loo kala firdhiyo, waxaa si toos ah loogu dari karaa qaabka budada qalalan ama qaabka slurry marka la shiidi karo midabada iyo buuxinta.
3. Dhisme aad u wanaagsan.Waxay leedahay faa'iidooyinka badbaadinta shaqada, ma fududa in lagu tifxo oo la laadlaadsado, iyo iska caabin wanaagsan oo fidinta.
4. Waafaqid wanaagsan oo leh surfactants kala duwan iyo waxyaalaha ilaaliyayaasha loo isticmaalo rinjiga cinjirka.
5. Viscosity kaydinta waa mid deggan, kaas oo ka hortagi kara viscosity ee rinjiga cinjirka ah inuu hoos u dhaco sababtoo ah kala-goynta enzymes ee guud ahaan hydroxyethyl cellulose.
Astaamaha Hydroxyethyl Cellulose
Hydroxyethyl cellulose ether waa polymer aan-ionic biyo-milmi leh.Waa budo jaale ah oo cad ama khafiif ah oo si fudud u socota.Guud ahaan aan lagu milmi karin inta badan dareerayaasha organic
1. HEC waxay ku milmaysaa biyo kulul ama biyo qabow, oo kuma soo da'ayaan heerkulka sare ama karkarinta, taas oo ka dhigaysa inay leedahay noocyo kala duwan oo milmayn iyo sifooyin viscosity, iyo gelation non-thermal.
2. Waa non-ionic oo waxay la noolaan kartaa polymers-ka kale ee biyaha ku milma, surfactants, iyo cusbada.Waa dhumuc weyn oo kolloidal ah oo loogu talagalay xalalka ka kooban elektrolytka-fiirsashada sare.
3. Awoodda haynta biyuhu waxay laban laab ka badan tahay tan methyl cellulose, waxayna leedahay nidaaminta qulqulka wanaagsan.
4. 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 (midab leh).
Dhumayn
Saamayn ku yeelashada kartida shaqada, sida: hufnaanta, caabbinta faafinta, caabbinta luminta;qaab dhismeedka shabakada gaarka ah ee ether cellulose waxay xasilin kartaa budada nidaamka daahan, hoos u dhigista dejinta, oo ka dhigaysa nidaamka inuu helo saameyn kayd ah oo wanaagsan.
Biyo iska caabin wanaagsan
Ka dib marka filimka rinjiga uu si buuxda u qallalo, wuxuu leeyahay iska caabin biyo aad u fiican.Tani waxay si gaar ah u muujinaysaa qiimaha caabbinta biyaha ee nidaamka qaabaynta sare-PVC.Laga soo bilaabo ajnabi ilaa qaababka Shiinaha, nidaamkan sare-PVC, qadarka etherka cellulose ee lagu daray asal ahaan waa 4-6‰.
biyo-hayn aad u fiican
Hydroxyethyl cellulose waxay sii dheerayn kartaa wakhtiga soo-gaadhista waxayna xakamaysaa wakhtiga qalajinta si loo helo samaynta filim wanaagsan;iyaga ka mid ah, haynta biyaha ee methyl cellulose iyo hypromellose ayaa si aad ah hoos ugu dhacaya 40 ° C, iyo qaar ka mid ah cilmi-baarisyada ajnabiga ah waxay aaminsan yihiin in la dhimi karo 50% , suurtogalnimada dhibaatooyinka xagaaga iyo heerkulka sare ayaa si weyn u kordhay.
Degenaansho wanaagsan si loo yareeyo qulqulka rinjiga
Baabi'in sedbursiga, sineresis iyo flocculation;Dhanka kale, hydroxyethyl cellulose ether waa nooc aan-ionic ahayn oo badeecad ah.Aan ka falcelin waxyaallaha kala duwan ee nidaamka.
Waafaqid wanaagsan oo leh nidaamka midabada badan
Waafaqid heer sare ah ee midabeeyayaasha, midabka iyo buuxinta;Hydroxyethyl cellulose ether ayaa leh midabka ugu fiican, laakiin ka dib marka la beddelo, sida methyl iyo ethyl, waxaa jiri doona khataro qarsoon oo ku habboon midabka midabka.
Ku habboonaanta wanaagsan ee alaabta ceeriin ee kala duwan
Waxaa loo isticmaali karaa in hababka qaabaynta daahan kala duwan.
Dhaqdhaqaaqa antimicrobial sare
Ku habboon nidaamyada silicate
