CMC waxay u isticmaashaa rinjiyeynta iyo Warshadaha Dahaarka

Rinjiyeynta heerka karboxymethyl cellulose sodiumayaa leh dhumuc wanaagsan, kala firdhisanaan iyo xasillooni, waxay hagaajin kartaa viscosity iyo rheology ee dahaarka, sidaas darteed waxaa si ballaaran loo isticmaalaa in dahaarka kala duwan, dahaarka cinjirka, dahaarka dibadda iyo gudaha biyaha ku salaysan, dahaarka tuuraya iyo wixii la mid ah.

Isticmaalka degdega ahrinji heerka karboxymethyl cellulose:

Waxa loogu yeero xal degdeg ah waxay ka dhigan tahay in budada CMC la kala firdhi karo oo si dhakhso ah loogu milmi karo xal aqueous heerkulka qolka, taas oo ka duwan nooca caadiga ah ee CMC si tartiib ah u milmay (nooca caadiga ah ee CMC wuxuu u baahan yahay ugu yaraan 2-3 saacadood oo sare- kicinta xawaaraha si gebi ahaanba loo kala diro). Viscosity ee darajada daahan daahan degdeg ah carboxymethyl cellulose CMC isla markiiba ma gaadhi doonto ay viscosity dhabta ah la kala diri degdeg ah ee budada ah, oo waxay noqon doontaa in 10-15 daqiiqo ka dib kala diri ee viscosity ah, formation of viscosity dhabta ah gaari karaa kolloid ah. . Intaa waxaa dheer, xasiloonida kolloid ee degdegga ah ee CMC waxay ka fiican tahay kan caadiga ah ee CMC oo leh tilmaamo isku mid ah.

Isla markiibamilmayCarboxymethyl cellulose CMC waxaa si weyn loogu isticmaalaa dhammaan noocyada daahan biyaha ku salaysan, sida cinjirka cad, rinjiga cinjirka, putty, rinjiga gargaarka, rinjiga dhagax dabiiciga ah, iwm.

Faa'iidooyinkarinji heerka karboxymethyl cellulose:

A) Dahaarka oo aan lakab lahayn oo la ilaalin karo muddo dheer;

B) Waxay ku siin kartaa badeecooyin gaar ah oo degdeg ah u kala diri kara codsiyada daahan ee meelaha gaarka ah;

C) Si wax ku ool ah u hagaajiso rheology of glaze slurry, fududayso codsiga dhaldhalaalka, oo ka dhig slurry glaze xaalad fidsan oo deggan;

D) Si wax ku ool ah u wanaaji xoogga dhaldhalaalka iyo sinnaanta si looga hortago xaalufka;

E) Hubi habka daabacaadda ee wax soo saarka glaze daabacaadda, iyo qaababka daabacan ay yihiin kuwo cad oo qurux badan;

F) Ma jiri doonto xannibaad ku socota habka daabacaadda glaze-ka, CMC waxay leedahay biyo nadiif ah oo wanaagsan oo ku dhawaad ​​​​ma jiraan walxo aan milmi karin sida fiber wasakh ah;

Rinjiyeynta darajoCMCHabka kala dirida carbonoxymethyl cellulose:

Therinji cellulose karboksymethyl si toos ah ayaa loogu qasaa biyo waxaana loo diyaariyey xabagta koollada si hadhow loo isticmaalo. Heerka daahan qaabeynta koollada carboxymethyl cellulose, marka hore la qaso maaddooyinka dhirta ee dhululubo in ay ku biiraan xaddi gaar ah oo biyo nadiif ah, in furan hoos xaaladda qalabka walaaqaya, heerka daahan ee carboxymethyl cellulose si tartiib ah oo siman si maaddooyinka ku jira dhululubo , walaaq si joogto ah, ka dhigi carboxymethyl cellulose rinjiga iyo fiyuuska heerka biyaha, carboxymethyl cellulose si buuxda u dhalaali karaa heerka daahan. Marka rinjiga dhalaalayodarajo Carboxymethyl cellulose, sababta si siman u faafo, iyo si joogto ah walaaqaya, ujeedadu waa "in looga hortago fasalka rinjiga karboxymethyl fiber iyo biyaha la kulmo, agglomeration, agglomeration, la yareeyo heerka rinjiga carboxymethyl cellulose dhibaatada solubility", iyo hagaajinta heerka kala diri ee fasalka rinjiga carboxymethyl cellulose. Waqtiga walaaqaya iyo darajada rinjiga karboksymethyl cellulose dhamaystiran wakhtiga kala diridu ma aha mid joogto ah, waa laba fikradood, guud ahaan hadalka, wakhtiga walaaqaya aad ayuu uga gaaban yahay darajada rinjiga karboxymethyl cellulose oo dhamaystiran wakhtiga kala dirida, wakhtiga loo baahan yahay waxay kuxirantahay xaalada gaarka ah.

Go'aami waqtiga kareyso oo ku saleysan: marka carboxymethyl cellulose biyaha si siman u kala firdhiyey, ma jiraan wax cad oo buro weyn, aad joojin kartaa walaaqaya, si carboxymethyl cellulose iyo biyaha in xaalad taagan ee lays labada dhinac, Fiyuuska labada dhinac.

Go'aami karboxymethyl cellulose si dhammaystiran u milmay wakhtiga loo baahan yahay iyadoo lagu salaynayo dhinacyada soo socda:

(1) darajada rinjigaCMCCarboxymethyl cellulose iyo biyaha ayaa si buuxda u xidhan, mana jirto kala soocida dareeraha adag ee u dhexeeya;

(2) Dheecaan isku dhafan ayaa ku jira xaalad labis ah, oo dusha sare waa siman;

(3) Midabka aleurone isku dhafan wuxuu ku dhow yahay mid aan midab lahayn oo hufan, mana jiraan wax granular ah oo ku jira aleurone. Laga soo bilaabo darajada rinjigaCMCCarboxymethyl cellulose waxaa lagu shubaa haanta isku dhafka biyaha, ilaa heerka rinjigaCMCCarboxymethyl cellulose ayaa si buuxda u milmay, wakhtiga loo baahan yahay inta u dhaxaysa 10 ilaa 20 saacadood.
