Umthelela we-cellulose ether ku-putty powder

1. i-cellulose ether - i-cellulose ether eyandulelayo

I-Cellulose ether iyi-polysaccharide egcwele kakhulu emhlabeni namuhla.Imithombo eyinhloko ye-cellulose yemvelo ikotini, izihlahla, izitshalo zasemanzini, utshani nokunye.Ukotini uqukethe i-92-95% cellulose;I-Flax iqukethe cishe ama-80% we-cellulose;Ukhuni luqukethe cishe u-50% we-cellulose.

2, isakhiwo se-cellulose ether

I-Cellulose ether iyi-polysaccharide eyinkimbinkimbi equkethe izinkulungwane zamayunithi e-glucose ku-molecule, ifomula yamakhemikhali ithi (C6H10O5) N. Iqembu le-D-glucose liboshwe ngamabhondi e-β - 1,4 glucoside.

Izinkinga ezivamile kanye nezimbangela eziyinhloko zokumelana kwamanzi putty odongeni lwangaphakathi

Izindlela ezijwayelekile zokuxazulula izinkinga

I-putty emaphakathi:

I-Depowder: i-cementitious material enganele, ukugcinwa kwamanzi kwe-cellulose ether akwanele, okuqukethwe kwe-calcium ye-calcium esindayo kuphansi.

Ukusebenza kokwakha: kuthuthukiswe yi-bentonite ne-starch ether.

Isigubhu esingenalutho;Nokunamathela odongeni okubangelwa ukungenele.

Ukwendlalela: ukucubungula isixhumi esibonakalayo.

Amandla: Ingabuye ishintshwe ngokufaka i-calcium powder.

I-lime calcium putty:

Izinkinga isigubhu esingenalutho, i-depowder yellowing, ukwakhiwa akukuhle, i-depowder, i-stratification, ukuqhekeka, emva kokuqina;

I-Depowder: i-cementitious material enganele, ukugcinwa kwamanzi kwe-cellulose enganele noma inani elinganele lokwengeza, i-lime calcium ayihlanzekile.

Ukusebenza kahle kokwakhiwa: i-bentonite ne-starch ether ukuze kuthuthukiswe.

Isigubhu esingenalutho;Futhi ukunamathela odongeni okunganele okubangelwa ukungezwa okufanele kwe-latex powder.

Ukwendlalela: ukucubungula isixhumi esibonakalayo.

Okuphuzi: ukukhetha okungalungile kwe-cellulose ether.

Ukuqhekeka: ukuqhekeka kwesisekelo noma amandla okuqhekeka aqine kakhulu, ukunamathela kukhulu kakhulu.

Ngemuva kokuqina: izinga lokumunca amanzi e-calcium elisindayo lihlukile, kunconywa ukuthi ukhethe ukumuncwa kwamanzi okuyi-zero noma i-powder ye-calcium enzima kakhulu;I-calcium empunga iqukethe i-GaO engagayekile.

I-putty esekelwe kusimende:

Izinkinga zesigubhu esingenalutho, ukwakhiwa akukuhle, i-depowder, i-delamination, ukuqhekeka, ukumelana kwamanzi okwanele, ukuhlangana okungamanga;

I-Depowder: impahla kasimende enganele, ukugcinwa kwamanzi kwe-cellulose ether enganele noma inani elingenele lokwengeza.

Ukusebenza kahle kokwakhiwa: i-bentonite ne-starch ether ukuze kuthuthukiswe.

Isigubhu esingenalutho: nokunamathela odongeni okubangelwa ukunganeli, ukwengeza okunengqondo kwempushana ye-latex.

Ukwendlalela: ukucubungula isixhumi esibonakalayo.

Okuphuzi: Ukukhetha okungalungile kwe-cellulose.

Ukumelana namanzi okwanele: i-latex powder enganele kanye nezinto ezinganele zikasimende.

Ukuqhekeka: ukuqhekeka kwesisekelo noma ukuqhekeka kwamandla aphezulu kakhulu, ukunamathela kukhulu kakhulu, nge-putty ukugcwalisa umgodi.

I-coagulation engamanga: i-sodium gluconate ingangezwa ukwandisa isikhathi sokusebenza.
