Warqad-samaynta darajada CMC Sodium carboxymethyl cellulose waxay leedahay adhesion aad u fiican, dhumucdiisuna, emulsion, ganaax, flocculation, filim, kolloid ilaalinta, biyaha ceshan, xasiloonida kiimikada iyo sifooyinka wanaagsan sida affinity fiber saxarka, hordhaca ah ee kooxaha karboksymethyl hydrophilic in ay qaab-dhismeedka kelli, ka dhig bararka cellulose ayaa si weyn u kordhay, fududahay in la xoqo fiber-ka iyo walxaha buuxinta, kor u qaadida adkaanta iyo xoogga warqadda; Waxay kor u qaadi kartaa saxarka iyo buuxinta oo leh kharash taban iyo is-dhaafsi, si fiilada iyo buuxinta ay si siman u kala firdhiyaan saxarka, waxay hagaajiyaan isku-duubnida warqadda; Warqad samaynta darajada CMC Waxaa loo isticmaali karaa wakiilka cabbirka dusha sare si loo hagaajiyo xoogga iyo simanaanta warqadda; Waxay si fiican u kala firdhi kartaa midabaynta waxayna hagaajinaysaa saamaynta daabacaadda iyo dheehidda. Waxay hagaajin kartaa saamaynta xajinta biyaha iyadoo la xakameynayo lana hagaajinayo rheology ee daahan. Waxay muujin kartaa caddaymo ka wanaagsan saamaynta istaarijka, polyetylen glycol iyo sideyaal kale oo iftiimaya, waa kaaliye samaynaysa waraaqo shaqaynaysa oo badan.

Codsiga

Warshadaha waraaqaha, CMC waxaa loo isticmaalaa habka pulping, kaas oo hagaajin kara heerka haynta iyo kordhinta xoogga qoyan. Loo isticmaalo cabbirka dusha sare, sida soosaar midabaynta, hagaajinta adhesion gudaha, yaraynta boodhka daabacaadda, hagaajinta tayada daabacaadda; Loo isticmaalo dahaadhka warqadda, waxay ku habboon tahay kala firdhisanaanta iyo dareeraha midabka midabka, waxay xoojisaa jilicsanaanta waraaqaha, jilicsanaanta, sifooyinka indhaha iyo la qabsiga daabacaadda. In warshadaha waraaqaha sida qiimo wax ku ool ah iyo tiro balaadhan oo ah daro, inta badan sababta oo ah ay samaynta filim polymer biyaha-milla iyo caabbinta saliidda.

● Waxaa loo isticmaalaa in lagu cabbiro warqadda, si markaas warqaddu u yeelato cufnaan sare, caabbinta khad fiican, ururinta dhuka sare iyo siman.

● Waxay hagaajin kartaa heerka viscosity fiber-ka gudaha warqadda, si ay u wanaajiso awoodda warqadda iyo iska caabinta laalaabida.

● Habka midabaynta waraaqaha iyo warqadda, CMC waxay ka caawisaa inay xakamayso qulqulka koollada midabka iyo nuugista khad wanaagsan.

Guud ahaan, qiyaasta lagu taliyey waa 0.3-1.5%.

Baakadaha:

Alaabada CMC waxa ay ku xidhan tahay saddex bac oo xaashi ah oo ay ku jirto bac polyetylen ah oo gudaha ah oo la xoojiyay, miisaanka saafiga ahi waa 25kg kiishadiba.
