Falanqaynta Noocyada Cellulose Ethers ee Lagu Isticmaalo Rinjiga Latex
Ether-ka cellulose waa mid ka mid ah qaybaha muhiimka ah ee rinjiga cinjirka ah. Iskudhisyadani waxay bixiyaan faa'iidooyin kala duwan oo ay ku jiraan xakamaynta viscosity, dhumucdi, iyo haynta biyaha. Waxay ka soo jeedaan cellulose, taas oo ah polymer-ka dabiiciga ah ee laga helo dhirta. Falanqayntan, waxaan kaga hadli doonaa noocyada kala duwan ee ether-ka cellulose ee loo isticmaalo rinjiga cinjirka ah iyo hantidooda.
Rinjiyeynta cinjirka ayaa ah rinji ku salaysan biyaha oo noqday nooca ugu caansan ee rinjiga sanadihii ugu dambeeyay sababtoo ah sahlanaanta isticmaalka, ur yar, iyo deegaanka saaxiibtinimo. Qaybta ugu muhiimsan ee rinjiga cinjirka ah waa polymer-ka-xidhaha, kaas oo caadi ahaan ah isku-darka noocyada kala duwan ee ethers cellulose. Ether-yadan cellulose-ku waxay u shaqeeyaan sidii dhumucyada, wax ka beddelayaasha rheology, iyo xasiliyayaal si kor loogu qaado waxqabadka rinjiga. Falanqayntan, waxaan ku baari doonaa noocyada kala duwan ee ether-ka cellulose ee loo isticmaalo rinjiga cinjirka ah iyo hantidooda.
Methyl Cellulose (MC) Methyl cellulose waa mid ka mid ah ether-ka cellulose-ka inta badan la isticmaalo ee rinjiga cinjirka ah. Waa biyo-milmi kara, budo cad oo ka timid cellulose iyada oo loo marayo fal-celin kiimikaad leh methanol. MC waxaa lagu yaqaanaa sifooyinkeeda biyo-haysinta ee ugu wanaagsan, taasoo ka dhigaysa doorasho caan ah qaababka u baahan waqtiyo qallajin oo dheer. Waxa kale oo loo isticmaalaa sida wakiilka dhumuc sababtoo ah awoodda ay u leedahay in ay kordhiso viscosity iyo hagaajinta guryaha socodka. Intaa waxaa dheer, MC waxa ay wanaajin kartaa ku-dhejinta rinjiga ee sagxadaha, taasoo ka dhigaysa shay aad u badan oo ka mid ah hababka rinjiga cinjirka ah.
Hydroxyethyl Cellulose (HEC) Hydroxyethyl cellulose waa eter kale oo si caadi ah loo isticmaalo rinjiga cinjirka ah. Waa biyo-milmi kara, budo cad oo ka soo jeeda cellulose iyada oo loo marayo fal-celin kiimikaad leh ethylene oxide. HEC waxay caan ku tahay sifooyinkeeda dhumucyada wanaagsan, taas oo ka dhigaysa doorasho caan ah qaababka u baahan viscosity sare. Waxa kale oo loo isticmaalaa sidii binder, kaas oo gacan ka geysanaya hagaajinta ku dhejinta rinjiga ee dusha sare. Intaa waxaa dheer, HEC waxay wanaajin kartaa caabbinta biyaha ee rinjiga, taasoo ka dhigaysa shay faa'iido leh oo ka mid ah qaababka rinjiga cinjirka dibadda.
