darajada Dharka CMC

Heerka dunta CMC Sodium carboxymethyl cellulose waxaa loo isticmaalaa warshadaha dharka sida wakiilka cabbirka, wakiilka dhumuc ee daabacaadda iyo saxarka midabaynta, daabacaadda dharka iyo dhamaystirka adkaanta. Loo isticmaalo wakiilka cabbirka ayaa wanaajin kara milanka iyo viscosity-ka, iyo nadiifinta fudud; Sida wakiilka dhamaystirka adag, qiyaasteedu waxay ka badan tahay 95%; Marka loo isticmaalo sida wakiilka cabbirka, xoogga iyo dabacsanaanta filimka cabbiridda ayaa si cad loo wanaajiyaa. Natiijooyinku waxay muujinayaan in marka fiirsashada xalka CMC ay ku saabsan tahay 1% (W / V), waxqabadka chromatographic ee saxanka lakabka khafiifka ah ee la diyaariyey ayaa ka fiican. Isla mar ahaantaana, saxanka lakabka khafiifka ah ee lagu daboolay shuruudaha la hagaajiyay ayaa leh awoodda lakabka ku habboon, taas oo ku habboon muunad kala duwan oo lagu daro tignoolajiyada iyo ku habboon hawlgalka. CMC waxay ku dheggan tahay fiilooyinka intooda badan waxayna wanaajin kartaa xidhiidhka ka dhexeeya fiilooyinka. Viscosity-keeda xasilloon waxay hubisaa isku-dhafka cabbirka, sidaas awgeed waxay hagaajinaysaa waxtarka dharka. Waxa kale oo loo isticmaali karaa wakiilka dhamaystirka dharka, gaar ahaan dhamaystirka ka-hortagga laalaabka, si loo keeno isbeddello waarta.

Darajada Dharka CMC waxay wanaajin kartaa wax-soo-saarka iyo xoogga geeddi-socodka dunidda dunta. Loo isticmaalo daabacaadda dunta iyo dheehidda, sida wakiilka hakinta alaabta ceeriin, hagaajinta heerka curaarta iyo tayada daabacaadda, lagu taliyay in lagu wareego 0.3-1.5%, 0.5-2.0% daabacaadda iyo dheehidda.

Acodsiga CMC ee warshadaha dharka

 

1. Cabbirka dharka

Isticmaalka CMC ee beddelka cabbirka hadhuudhka waxay ka dhigi kartaa dusha dusheeda siman, xidhashada adkaysta oo jilicsan, sidaas awgeed waxay hagaajinaysaa awoodda wax-soo-saarka ee loom. Dufanka dunta ah iyo marada cudbigu waa khafiif, ma fududa in ay xumaato iyo caariyaysigu, way fududahay in la ilaaliyo, sababtoo ah cabbirka cabbirka CMC wuu ka hooseeyaa hadhuudhka, markaa ma jirto desizing daabacaadda suufka iyo midabaynta.

 

2. daabacaadda dharka iyo dheehidda

CMC ee daabacaadda iyo dheehidda ma fududa in lagaga falceliyo midabyo falcelinaya. Heerka dhejinta wanaagsan, kaydinta xasilloon; Qaab dhismeedka viscosity sare, awoodda haynta wanaagsan ee biyaha, ku habboon shaashadda wareega, shaashadda fidsan iyo daabacaadda gacanta; Iyada oo rheology wanaagsan, waxay ku habboon tahay daabacaadda qaabka wanaagsan ee dharka fiber hydrophilic marka loo eego sodium alginate, iyo saameynta daabacaadda dhabta ah waxay la mid tahay tan sodium alginate. Waxaa loo isticmaali karaa daabacaadda koollada halkii laga isticmaali lahaa sodium alginate ama lagu daro sodium alginate.

 

Baakadaha:

Dharka darajada dharka ee CMC Alaabta waxaa lagu soo raray saddex bac oo xaashi ah oo leh bac polyetylen ah oo gudaha ah oo la xoojiyay, culeyska saafiga ah waa 25kg shandadba.
