Umphumela we-cellulose ether ku-putty powder

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

I-ether ye-celluloseyi-polysaccharide eningi kakhulu emhlabeni namuhla. Imithombo eyinhloko ye-cellulose yemvelo ikotini, izihlahla, izitshalo zasemanzini, utshani njalo njalo. Ukotini uqukethe i-cellulose engu-92-95%; I-flax iqukethe i-cellulose engu-80%; Izinkuni ziqukethe i-cellulose engu-50%.

2, isakhiwo se-cellulose ether

I-cellulose ether iyi-polysaccharide eyinkimbinkimbi equkethe izinkulungwane zamayunithi e-glucose ku-molecule, ifomula yamakhemikhali yi-(C6H10O5) N. Iqembu le-D-glucose liboshwe yizibopho ze-β – 1,4 glucoside.

Izinkinga ezivamile kanye nezimbangela eziyinhloko ze-putty yokumelana namanzi odongeni lwangaphakathi

Izindlela ezivamile zokuxazulula izinkinga

I-putty engathathi hlangothi:

Ukungcola: ukungabi khona kwezinto eziqinisayo ngokwanele, ukugcinwa kwamanzi e-cellulose ether akwanele, okuqukethwe kwe-calcium eningi kuphansi.

Ukusebenza kokwakhiwa: kuthuthukiswe yi-bentonite kanye ne-starch ether.

Isigubhu esingenalutho; Nokunamathela odongeni okubangelwa ukunganele.

Ukubeka: ukucubungula isikhombimsebenzisi.

Amandla: Kungalungiswa futhi ngokuhlela i-calcium powder.

I-calcium putty ye-lime:

Izinkinga ziyi-drum engenalutho, i-depowder ishintsha ibe phuzi, ukwakheka kwayo akukuhle, i-depowder, i-stratification, i-cracking, ngemva kokujiya;

Ukungcola: ukungabi khona kwezinto eziqinisa ulwelo, ukungabikho kwamanzi e-cellulose anele noma ukungabi khona kwenani elanele lokwengeza, i-calcium ye-lime ayihlanzekile.

Ukusebenza kabi kokwakhiwa: i-bentonite ne-starch ether kufanele kuthuthukiswe.

Isigubhu esingenalutho; Nokunganamatheli odongeni okwanele okubangelwa ukufakwa okufanele kwempuphu ye-latex.

Ukubeka: ukucubungula isikhombimsebenzisi.

Ukuphuzi: ukukhetha okungafanele kwe-cellulose ether.

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

Ngemva kokuqina: izinga lokumuncwa kwamanzi e-calcium elinzima lihlukile, kunconywa ukuthi ukhethe ukumuncwa kwamanzi okungekho noma i-calcium impuphu ephansi kakhulu; i-calcium empunga iqukethe i-GaO engagaywanga.

I-putty esekelwe kusimende:

Izinkinga zesigubhu esingenalutho, ukwakhiwa akukuhle, ukubola, ukuhlukanisa, ukuqhekeka, ukumelana namanzi okwanele, ukujiya okungamanga;

Ukungcola: ukungabi khona kwezinto eziqinisa ulwelo, ukungabikho kwamanzi anele e-cellulose ether noma ukungabi khona kokwengezwa okwanele.

Ukusebenza kabi kokwakhiwa: i-bentonite ne-starch ether kufanele kuthuthukiswe.

Isigubhu esingenalutho: kanye nokunamathela odongeni okubangelwa ukungafakwa ngokwanele kwempuphu ye-latex.

Ukubeka: ukucubungula isikhombimsebenzisi.

Ukuphuzi: Ukukhetha i-cellulose okungalungile.

Ukumelana namanzi okwanele: ukuntuleka kwempuphu ye-latex kanye nezinto zokwakha ezisansimbi ezinganele.

Ukuqhekeka: ukuqhekeka kwesisekelo noma ukuqhekeka okunamandla kakhulu, ukumbozwa kukhulu kakhulu, nge-putty yokugcwalisa umgodi.

Ukujiya okungamanga: i-sodium gluconate ingangezwa ukuze kwandiswe isikhathi sokusebenza.
