Umsebenzi kanye nokusetshenziswa kwe-cellulose ether odakeni oluxubile olulungile

I-Cellulose ether ikakhulukazi inemisebenzi emithathu elandelayo:
1) Ingakwazi ukushubisa udaka olusha ukuze kuvinjelwe ukuhlukaniswa futhi ithole umzimba wepulasitiki ofanayo;
2) Inomsebenzi wokungena komoya futhi ingakwazi nokusimamisa amabhamuza amancane afaniswayo angeniswa odakeni;
3) Njenge-ejenti yokugcina amanzi, kuyasiza ukugcina amanzi (amanzi amahhala) ongqimbeni oluncane lodaka, ukuze usimende ube nesikhathi esengeziwe sokukhipha amanzi ngemva kokwakhiwa kodaka.
Kudaka olomile oluxubile, i-methyl cellulose ether idlala indima ekugcineni amanzi, ukuqina kanye nokwenza ngcono ukusebenza kokwakhiwa. Ukusebenza kahle kokugcinwa kwamanzi kuqinisekisa ukuthi udaka ngeke lubangele ukuncipha kwesihlabathi, impushana namandla ngenxa yokushoda kwamanzi kanye nokungapheleli kahle kukasimende; Umthelela wokujiya uthuthukisa kakhulu amandla esakhiwo sodaka olumanzi, njengekhono elihle lokulwa nokuncibilika lokunamathela kuthayela; Ukwengezwa kwe-methyl cellulose ether ngokusobala kungathuthukisa i-viscosity emanzi yodaka olumanzi, olune-viscosity enhle kuma-substrates ahlukahlukene, ngaleyo ndlela kuthuthukisa ukusebenza kodonga lodaka olumanzi nokunciphisa imfucuza.
Uma usebenzisa i-cellulose ether, kufanele kuqashelwe ukuthi uma inani le-cellulose ether liphezulu kakhulu noma i-viscosity iphezulu kakhulu, isidingo samanzi sizokhula, futhi ukwakhiwa kuzoba nzima (ukunamathisela) futhi ukusebenza kuzoncishiswa. I-cellulose ether ingabambezela isikhathi sokusetha sikasimende, ikakhulukazi uma umthamo uphezulu. Ngaphezu kwalokho, i-cellulose ether izophinde ithinte isikhathi sokuvula, ukumelana nokugeleza okuqondile namandla ebhondi odaka.
I-cellulose ether efanele kufanele ikhethwe emikhiqizweni ehlukene, futhi imisebenzi yayo nayo ihlukile. Isibonelo, i-MC ene-viscosity ephakeme kufanele ikhethwe ku-adhesive tile ye-ceramic, enganweba isikhathi sokuvula nesikhathi esilungisekayo, futhi ithuthukise ukusebenza kwe-anti slip; I-MC ene-viscosity ephansi kufanele ikhethwe ku-self leveling mortar ukuze kugcinwe uketshezi lodaka, futhi idlala indima ekuvimbeleni ukuhlukana nokuhlukaniswa nokugcinwa kwamanzi. I-cellulose ether efanele izonqunywa ngokuvumelana nezincomo zomkhiqizi kanye nemiphumela yokuhlolwa ehambisanayo.
Ukwengeza, i-cellulose ether inomphumela wokuzinzisa igwebu, futhi ukwakheka kwefilimu kwasekuqaleni kuzodala ukwakheka kodaka. I-microstructure ye-cellulose ether enamathelayo ethayela le-ceramic esanda kuxutshwa futhi eqiniswe yahlolwa yi-University of Bern kanye ne-National Starch Chemical Company e-Switzerland. Ukuhlolwa kwenkambu okuboniswe Emdwebeni kutholwe ukuthi i-cellulose ether igxilisa amabhamuza odakeni olusha ngokwakhiwa kwefilimu. Lawa mafilimu e-cellulose ether kungenzeka akhiwe ngesikhathi noma ngemva nje kokunyakaziswa, futhi impushana yerabha ehlakazekayo ayikaqali ukwenza amafilimu. Ingqikithi yalesi simo umsebenzi ongaphezulu we-cellulose ether. Njengoba amabhamuza elethwa i-agitator ngendlela engokwenyama, i-cellulose ether ithatha ngokushesha ukuxhumana phakathi kwamabhamuza nodaka lukasimende ukuze kwakhe ifilimu. Lawa mafilimu asemanzi, ngakho aguquguquka kakhulu futhi acindezeleke, kodwa umphumela we-polarization uqinisekisa ngokucacile ukuhlelwa okuhlelekile kwama-molecule awo. Kamuva, lawa mafilimu e-cellulose ether angatholakala onqenqemeni lwezimbotshana ngaphansi kwesibonakhulu se-electron yokuskena, njengoba kuboniswe kuMfanekiso.
Njengoba i-cellulose ether iyi-polymer encibilika emanzini, izofudukela phezulu lapho udaka luthinta khona umoya ngokuhwamuka kwamanzi odaka olusha ukuze kwakheke ukunothisa, okuholela ekukhishweni kwe-cellulose ether ebusweni bodaka olusha. Ngenxa yokukhishwa kwesikhumba, ifilimu enomzimba oqinile yenziwa endaweni yodaka, ezonciphisa isikhathi sokuvula sodaka. Uma ithayela le-ceramic linamathiselwe phezu kodaka ngalesi sikhathi, ifilimu izophinde isatshalaliswe ngaphakathi kodaka kanye nesixhumi esibonakalayo phakathi kwethayela le-ceramic nodaka, ngaleyo ndlela kuncishiswe amandla esibopho esikhathini sakamuva . Ukukhishwa kwesikhumba se-cellulose ether kungancishiswa ngokulungisa ifomula, ukukhetha i-cellulose ether efanelekile kanye nokwengeza ezinye izithasiselo.

I-Youngcel HPMC/MHEC isetshenziswa kabanzi njenge-Chemical Auxiliary Agent ye-Tile Adhesive, Cement Plaster, Dry mix mortar, Wall putty, Coating, Detergent nokunye.Futhi singakunikeza amanani aphansi kanye nekhwalithi engcono kakhulu.
