Hydroxyethyl cellulose

Hydroxyethyl cellulose (HEC) waa caddaan ama iftiin jaale ah, ur aan lahayn, fibros aan sun ahayn ama budo leh oo adag oo lagu diyaariyey etherification of cellulose alkaline iyo ethylene oxide (ama chlorohydrin).Nonionic ethers cellulose milmay.Sababtoo ah HEC waxay leedahay sifooyin wanaagsan oo dhumucdiisuna waxay tahay, hakin, kala firdhiyo, emulsifying, bonding, film-samaynta, ilaalinta qoyaanka iyo bixinta kolloid ilaalinta, waxa si weyn loogu isticmaalay sahaminta saliidda, dahaarka, dhismaha, daawada iyo cuntada, dunta, waraaqaha iyo polymers.Polymerization iyo qaybaha kale.Hydroxyethyl cellulose waa mid aan degganayn heerkulka caadiga ah iyo cadaadiska, isaga oo iska ilaalinaya qoyaanka, kulaylka, iyo heerkulka sare, wuxuuna leeyahay milmi milix ah oo gaar ah oo loogu talagalay dielectrics.Xalka aqueous waxaa loo ogol yahay in ay ku jiraan xaddi badan oo cusbo ah oo xasilloon.

Tilmaamaha
Si toos ah ugu biir wax soo saarka

1. Ku dar biyo nadiif ah baaldi weyn oo ay ku rakiban yihiin blender dhogorta sare leh.

2. Bilow inaad si joogto ah u walaaqdo xawaare yar oo si tartiib ah u kala miir hydroxyethyl cellulose si siman xalka.

3. Sii wad walaaq ilaa dhammaan qaybaha la qooyay.

4. Ka dibna ku dar walxaha antifungal, daroogooyinka alkaline sida midabada, kala firdhinta qalabka, biyaha ammonia.

5. Walaaq ilaa dhammaan cellulose hydroxyethyl ay si buuxda u milmaan (viskosity ee xalku si aad ah ayuu u kordhiyaa) ka hor intaadan ku darin qaybaha kale ee caanaha, oo shiid ilaa alaabta la dhammeeyo.

Ku qalabaysan khamriga hooyada

Habkani waa in marka hore la diyaariyo khamriga hooyada oo leh feejignaan sare, ka dibna lagu daro rinjiga cinjirka.Faa'iidada habkani waa in uu leeyahay dabacsanaan weyn oo si toos ah loogu dari karo rinjiga la dhammeeyey, laakiin waa in si habboon loo kaydiyaa.Tallaabooyinka waxay la mid yihiin tillaabooyinka 1-4 ee habka 1, marka laga reebo in walaaqin sare aan loo baahnayn in si buuxda loogu milo xal viscous ah.

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

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 miiraa foostada isku dhafka ah.Si toos ah ha ugu darin hydroxyethyl cellulose ka loo sameeyay burooyin ama kubbado foosto isku qasan tiro badan ama si toos ah.

3. Heerkulka biyaha iyo qiimaha pH ee biyuhu waxay leeyihiin xidhiidh muhiim ah oo la xidhiidha milanka hydroxyethyl cellulose, markaa waa in fiiro gaar ah la siiyaa.

4. Waligaa walxo alkaline ah ha ku darin isku darka ka hor inta aan budada hydroxyethyl cellulose lagu diirin biyo.Kor u qaadista qiimaha PH ka dib kululaynta waxay caawinaysaa kala dirida.

5. Inta suurtogalka ah, ku dar wakiilka antifungal sida ugu dhakhsaha badan ee suurtogalka ah.

6. Marka la isticmaalayo hydroxyethyl cellulose viscosity-sare, fiirsashada khamriga hooyadu waa inuusan ka badnaan 2.5-3%, haddii kale khamriga hooyadu waa adag tahay in la shaqeeyo.Unugyada hydroxyethyl cellulose ee la daaweeyay ka dib guud ahaan ma fududa in la sameeyo buro ama goobo, mana samayn doono kolloysyada wareegsan ee aan milmi karin ka dib marka lagu daro biyo.
