Kala dirida iyo kala firdhida alaabta CMC

Si toos ah CMC ugu qas biyo si aad u samayso xabag bac ah oo hadhow loo isticmaalo. Markaad habaynayso xabagta CMC, marka hore waxaad ku dartaa xaddi biyo nadiif ah oo ku shub haanta dufinta oo leh qalab wax kicinaya, marka aaladda wax-karinta la shido, si tartiib ah oo siman CMC ugu rushaysaa taangiga dufcadda, adigoo si joogto ah u walaaqaya, si CMC uu si buuxda isugu daro. biyo, CMC si buuxda ayay u milmi kartaa.

Marka la milmiyo CMC, sababta ay tahay in si siman loo rusheeyo oo loo walaaqo si joogto ah waa in laga hortago dhibaatooyinka is-daba-mareenka, kor-u-qaadista, iyo in la yareeyo qadarka CMC ee milan marka CMC la kulmo biyaha", iyo in la kordhiyo heerka kala dirida CMC. Wakhtiga walaaqaya la mid ma aha wakhtiga CMC uu si buuxda u milmi karo. Waa laba fikradood. Guud ahaan, wakhtiga wax-karsiga aad ayuu uga gaaban yahay wakhtiga CMC uu si buuxda u milmi karo. Waqtiga loo baahan yahay labada waxay ku xiran tahay xaaladda gaarka ah.

Saldhigga lagu go'aaminayo waqtiga walaaqdu waa: marka CMC ay si isku mid ah ugu kala firirsan tahay biyaha oo aysan jirin kuusyo waaweyn oo muuqda, karitaanka waa la joojin karaa, taas oo u oggolaanaysaCMCiyo biyaha si ay u dhex galaan oo ay isugu darsamaan xaalad taagan. Xawaaraha walaaqdu guud ahaan waa inta u dhaxaysa 600-1300 rpm, wakhtiga wax kicinta guud ahaan waa la xakameeyaa ilaa 1 saac.

Saldhigga lagu go'aaminayo wakhtiga looga baahan yahay CMC inuu si buuxda u milmo waa sida soo socota:

(1) CMC iyo biyuhu si buuxda ayay isugu xidhan yihiin, mana jiraan wax kala soocida dareeraha adag ee labada u dhexeeya;

(2) Koolada isku dhafan waxay ku jirtaa xaalad labis ah, oo dusha sare waa siman oo siman;

(3) Midabka koollada isku dhafka ah waxay ku dhow yihiin midab la'aan iyo daah-furnaan, mana jiraan wax granular ah oo ku jira koollada. Laga bilaabo marka CMC la geliyo haanta wax lagu shubo ee lagu qaso biyaha ilaa wakhtiga uu CMC si buuxda u milmay, wakhtiga loo baahan yahay waa inta u dhaxaysa 10 ilaa 20 saacadood. Si loo soo saaro si dhakhso ah oo loo badbaadiyo wakhtiga, homogenizers ama warshadda kolloid ayaa inta badan loo isticmaalaa in si degdeg ah u kala firdhiso alaabta.
