Umsebenzi kanye nokusetshenziswa kwe-cellulose ether odakeni oseluxubile

I-Cellulose ether ikakhulukazi inemisebenzi emithathu elandelayo:

I-1) Ingakwazi ukuqinisa udaka olusha ukuvimbela ukuhlukaniswa futhi ithole umzimba wepulasitiki ofanayo;

I-2) Inomphumela wokungenisa umoya, futhi ingakwazi futhi ukuzinzisa iyunifomu namabhamuza omoya amahle angeniswa odakeni;

I-3) Njenge-ejenti egcina amanzi, isiza ukugcina amanzi (amanzi amahhala) odaka oluncane, ukuze usimende ube nesikhathi esengeziwe sokukhipha amanzi ngemva kokwakhiwa kodaka.

Odakeni oluxutshwe okomile, i-methyl cellulose ether idlala indima yokugcina amanzi, ukujiya kanye nokwenza ngcono ukusebenza kokwakhiwa. Ukusebenza kahle kokugcinwa kwamanzi kuqinisekisa ukuthi udaka ngeke lubangele ukugaywa kwesihlabathi, impushana kanye nokunciphisa amandla ngenxa yokushoda kwamanzi kanye nokungaphelele kukasimende; umphumela wokuqina uthuthukisa kakhulu amandla esakhiwo sodaka olumanzi, futhi ikhono elihle lokulwa nokugoqa lokunamathela kwe-tile yisibonelo; Ukwengezwa kwe-base cellulose ether kungathuthukisa kakhulu i-viscosity emanzi yodaka olumanzi, futhi kube ne-viscosity enhle kuma-substrates ahlukahlukene, ngaleyo ndlela kuthuthukise ukusebenza kodonga lodaka olumanzi futhi kunciphise imfucuza.

Uma usebenzisa i-cellulose ether, kufanele kuqashelwe ukuthi uma umthamo uphezulu kakhulu noma i-viscosity iphezulu kakhulu, isidingo samanzi sizokhula, futhi ukwakhiwa kuzozizwa kunzima (i-sticky trowel) nokusebenza kuzokwehla. I-Cellulose ether izobambezela isikhathi sokusetha sikasimende, ikakhulukazi uma okuqukethwe kuphezulu, umphumela wokuhlehlisa ubaluleke kakhulu. Ukwengeza, i-cellulose ether izophinde ithinte isikhathi esivulekile, ukumelana ne-sag namandla ebhondi yodaka.

I-cellulose ether efanele kufanele ikhethwe emikhiqizweni ehlukene, futhi imisebenzi yayo nayo ihlukile. Isibonelo, kuhle ukukhetha i-MC ene-viscosity ephakeme ekunamatheleni kwe-tile, engandisa isikhathi sokuvula nesikhathi esilungisekayo, futhi ithuthukise ukusebenza kokulwa nokushelela; ku-self-leveling mortar, kunconywa ukukhetha i-MC ene-viscosity ephansi ukuze kugcinwe uketshezi lodaka, futhi ngesikhathi esifanayo Iphinde isebenze ukuvimbela i-stratification nokugcinwa kwamanzi. Ama-cellulose ether afanelekile kufanele anqunywe ngokwezincomo zomenzi kanye nemiphumela yokuhlolwa ehambisanayo.

Ngaphezu kwalokho, i-cellulose ether inomphumela wokuzinzisa i-foam, futhi ngenxa yokubunjwa kwefilimu yasekuqaleni, izobangela ukukhishwa kwesikhumba odongeni. Lawa mafilimu e-cellulose ether angase akheke ngesikhathi noma ngokushesha ngemva kokunyakaziswa, ngaphambi kokuba impushana yerabha ehlakazeka kabusha iqale ukwenza ifilimu. Ingqikithi yalesi simo umsebenzi ongaphezulu we-cellulose ethers. Njengoba amabhamuza omoya elethwa ngokomzimba i-agitator, i-cellulose ether ithatha ngokushesha ukuxhumana phakathi kwamabhamuza omoya kanye nodaka lukasimende ukuze kwakhe ifilimu. Ama-membrane ayesemanzi futhi ngaleyo ndlela eguquguquka kakhulu futhi ecindezela, kodwa umphumela we-polarization waqinisekisa ngokucacile ukuhlelwa okuhlelekile kwama-molecule awo.

Njengoba i-cellulose ether iyi-polymer encibilika emanzini, izofuduka iye phezu kodaka oluthinta umoya ngokuhwamuka kwamanzi obishini olusha ukuze kwakheke ukunothisa, ngaleyo ndlela kubangele ukucutshungulwa kwe-cellulose ether ebusweni bodaka olusha. Ngenxa yokukhishwa kwesikhumba, ifilimu ye-denser yenziwa ebusweni bodaka, okunciphisa isikhathi esivulekile sodaka. Uma amathayela enamathiselwe phezu kodaka ngalesi sikhathi, lolu ungqimba lwefilimu luzophinde lusatshalaliswe ngaphakathi kodaka kanye nokuxhumanisa phakathi kwamathayili nodaka, ngaleyo ndlela kuncishiswe amandla okubopha kamuva. Ukukhishwa kwesikhumba se-cellulose ether kungancishiswa ngokulungisa ifomula, ukukhetha i-cellulose ether efanele kanye nokwengeza ezinye izithasiselo.
