Ukupheliswa kunye nokusasazwa kweemveliso zeCMC

Xuba i-CMC ngokuthe ngqo namanzi ukwenza iglu encamathelayo ukuze isetyenziswe kamva. Xa ulungiselela iglue yeCMC, faka kuqala umlinganiselo othile wamanzi acocekileyo kwitanki yokudibanisa ngesixhobo sokuxhokonxa, kwaye xa isixhobo esishukumisayo sivulwa, ngokucothayo nangokulinganayo ufefe i-CMC kwitanki ye-batching, uvuselela ngokuqhubekayo, ukuze i-CMC ihlanganiswe ngokupheleleyo. ngamanzi, i-CMC inokunyibilika ngokupheleleyo.

Xa unyibilika i-CMC, isizathu sokuba kufuneka ifafazwe ngokulinganayo kwaye ishukunyiswe ngokuqhubekayo kukuba "ukuthintela iingxaki ze-agglomeration, agglomeration, kunye nokunciphisa inani le-CMC elinyibilikisiweyo xa i-CMC idibana namanzi", kunye nokunyusa izinga lokuchithwa kwe-CMC. Ixesha lokuvuselela alifani nexesha le-CMC yokuchithwa ngokupheleleyo. Ziikhonsepthi ezimbini. Ngokubanzi, ixesha lokuvuselela lifutshane kakhulu kunexesha lokuba i-CMC inyibilike ngokupheleleyo. Ixesha elifunekayo kwezi zibini lixhomekeke kwimeko ethile.

Iimveliso zeCMC1

Isiseko sokumisela ixesha lokuvuselela kukuba: xa i-CMC ihlakazekile ngokulinganayo emanzini kwaye akukho ziqhuma ezinkulu ezicacileyo, ukuxhoma kunokumiswa, ukuvumela ukubaCMCkunye namanzi okugqobhoza kunye nokuxubana omnye komnye kwimo yokuma. Isantya esishukumisayo ngokuqhelekileyo siphakathi kwe-600-1300 rpm, kwaye ixesha lokuvuselela lilawulwa ngokubanzi malunga neyure enye.

Isiseko sokumisela ixesha elifunekayo ukuze i-CMC ichithwe ngokupheleleyo yile ilandelayo:

(1) I-CMC kunye namanzi zibotshelelwe ngokupheleleyo, kwaye akukho kwahlulo olululwelo oluqinileyo phakathi kokubini;

(2) Intlama exutyiweyo ikwimo efanayo, kwaye umphezulu usicaba kwaye ugudile;

(3) Umbala we-paste edibeneyo usondele kumbala kunye nokungafihli, kwaye akukho zinto zegranular kwi-paste. Ukusukela kwixesha apho i-CMC ifakwa kwitanki yokudibanisa kwaye ixutywe namanzi ukuya kwixesha xa i-CMC ichithwa ngokupheleleyo, ixesha elifunekayo liphakathi kwe-10 kunye ne-20 yeeyure. Ukuze uvelise ngokukhawuleza kwaye ugcine ixesha, i-homogenizers okanye i-colloid mills isoloko isetyenziselwa ukusabalalisa ngokukhawuleza iimveliso.
