3.Hydroxyethyl Cellulose (HEC) Codsiyada:

In rinjiga biyaha ku salaysan, waxa uu ka ciyaaraa door ah kala firdhiso iyo ilaalinta jel, kor loogu qaado xasiloonida falcelinta ee nidaamka agglomerate, hubinta qaybinta isku mid ah ee midabka iyo walxaha, iyo bixinta saamaynta dhumuc, hagaajinta dheecaanka.

Qoditaanka saliidda, waxaa loo isticmaalaa sida wakiilka xasilinta iyo dhumucyada, wakiilka saliidaynta qodista ceelasha, dhamaystirka iyo xoojinta si ay u siiso dareere wanaagsan iyo xasilooni.

Dhismaha, HEC waxaa loo isticmaali karaa sida wakiilka dhumuc iyo isku-duubni si loo hagaajiyo dareeraha iyo shaqeynta, kordhinta xoogga gelling bilowga ah iyo ka fogow dildilaaca.

Marka la cadaydo iyo isku xidhka balastar, waxa laga yaabaa inay si cad kor ugu qaaddo awoodda isku-xidhnaanta biyaha.

Kiimikada maalinlaha ah la isticmaalo sida daawada cadayga waxay siinaysaa hanti jidheed iyo kiimiko oo wanaagsan, taasoo ka dhigaysa qaab wanaagsan, kaydin muddo dheer ah, qallalan oo qallalan.

Goobta qurxinta, waxay kordhin kartaa cufnaanta walxaha, iyada oo ku daraysa saliidayn iyo siman.

Ka sokow, waxay leedahay codsi ballaaran oo khad ah, dhar-dhajinta iyo daabacaadda, warqad samaynta, daawooyinka, cuntada, beeraha iwm.

4.Hydroxyethyl Cellulose (HEC) Isticmaalka habka:

Habka Koowaad: Si Toos Ah U Geli

1. Ku shub biyo saafi ah baaldi lagu siiyay kiciya.

2. Bilawga si tartiib ah u walaaq, si siman u kala firdhi HEC xal.

3. Walaaq ilaa dhammaan granules HEC si buuxda u qoyso.

4. Marka hore waxaad gelisaa wax-ka-hortagga caariyaysiga,kadibna ku dar waxyaabaha lagu daro sida midabka,diperser iwm.

5. Sii wad walaaq ilaa dhammaan HEC iyo waxyaabaha lagu daro ay si buuxda u milmaan (viskosity ee xalka ayaa si cad u kordhaya), ka dibna ku rid maaddooyinka kale si ay uga falceliyaan.

Habka Labaad: U diyaari khamriga hooyada si loo isticmaalo

Marka hore diyaari khamriga hooyada qaro weyn, ka dibna ku dheji alaabta. Faa'iidada habka waa dabacsanaan, khamriga waxaa laga yaabaa in si toos ah loo dhexgeliyo alaabta. Habka iyo habka loo isticmaalo waxay la mid yihiin 1-4 habka (Ⅰ), be Hubi inaad walaaq ilaa inta si buuxda u milmay oo isku dhejisan oo dhumucdiisuna tahay oo ku rid wakiilka ka hortagga caarada khamriga hooyada sida ugu dhakhsaha badan ee suurtogalka ah.

Habka Seddexaad: U diyaari walxo u eg Gruel si loo isticmaalo

Maaddaama dareerayaasha organic yihiin kuwa aan xalin HEC, waxaa loo isticmaali karaa si ay u diyaariyaan walxaha gruel-sida. Inta badan la isticmaalo waa ethylene glycol, propylene glycol iyo film-samaynta wakiilka (hexamethylene-glycol, diethyl glycol butyl acetate iwm) sidaas darteed waa baraf. biyaha, waxa kale oo lagu diyaarin karaa dareerayaasha organic-ga ah oo loo samayn karo walxo u eg.

Maaddada roodhida la mid ah ayaa lagu dhejin karaa badeecada sababtoo ah HEC ee walxaha u eg si buuxda ayaa loo qooyay oo bararsan, ku rid alaabta si dhakhso ah u milmaan oo kor u qaad dhumucda, laakiin sii wad walaaq ilaa ay gebi ahaanba milanto.

Caadi ahaan maaddada ugxanta ah waxaa lagu helaa iyadoo lagu qaso dareeraha organic ama biyo baraf leh oo leh HEC saamiga 6:1, 5-30 daqiiqo ka dib HEC hydrolyzes oo si gaar ah u barara. Habka looma qaato xagaaga sababtoo ah cimilada kulul.

5.Hagaha Codsiga ee Warshadaha Rinjiga

Saamaynta Dhumucda Sare

Hydroxyethy cellulose waxay siisaa rinjiyada cinjirka ah gaar ahaan rinji PVA-ga sare leh oo leh waxqabadka dahaarka aad u fiican.Marka rinjigu yahay koollo qaro weyn, wax qulqulaya ma dhici doono.

Hydroxyethy Cellulose waxay leedahay saameyn dhumuc sare leh, sidaas darteed waxay yareyn kartaa qiyaasta, waxay hagaajin kartaa waxtarka-wax-ku-oolnimada diyaarinta, waxayna kor u qaadeysaa caabbinta rinjiga.

Guryaha Rheological heer sare ah

Xalka aqueous ee Hydroxyethy Cellulose waa nidaam aan Newtonian ahayn, iyo sifooyinka xalka waxaa loo yaqaan thixotropy.

Xaaladda taagan, ka dib markii alaabtu si buuxda u kala diraan, nidaamka dahaarka ayaa ilaalin kara xaaladda dhumucda ugu fiican iyo gobolka furan.

Xaaladda qashin-qubka, nidaamku wuxuu ilaalin karaa viscosity dhexdhexaad ah, samaynta alaabooyinka leh dareere aad u fiican, oo aan ku tusin.

Inta lagu jiro cadayashada iyo dahaarka rullaluistemadka, alaabtu way fududahay in lagu faafiyo substrate-ka, sidaas darteed ku habboon dhismaha, iyo Dhanka kale, waxay leedahay iska caabin wanaagsan.

Ugu dambeyntii, ka dib marka dahaarka rinjiga la dhammeeyo, viscosity ee nidaamka isla markiiba dib ayaa loo soo celin doonaa, rinji wuxuu isla markiiba soo saari doonaa hanti sagxad ah.

Kala firdhinta iyo milanka

Hydroxyethy Cellulose dhammaanteed waxaa lagu daaweeyaa kala diris dib u dhac ah, iyo haddii ay dhacdo in lagu daro budada qalalan, waxay si wax ku ool ah uga hortagi kartaa keega waxayna hubisaa in fuuq-baxa uu bilaabo ka dib faafinta ku filan ee budada HEC.

Hydroxyethy cellulose ka dib daawaynta saxda ah ee dusha sare waxay si fiican u nidaamin kartaa heerka kala dirida iyo heerka korodhka viscosity ee alaabta.

Xasiloonida Kaydinta

Hydroxyethy Cellulose waxay leedahay waxqabad wanaagsan oo caariyaysi u adkaysta, waxay siisaa wakhti ku filan kaydinta rinjiga, waxayna si wax ku ool ah uga hortagtaa dejinta midabka iyo buuxinta.
