I-Cellulose TETERS iyisigaba sama-polymers aphezulu we-molecular ancibilika amanzi asuselwa ku-cellulose. Basetshenziswe kabanzi embonini yezokwakha njenge-admixtures ethuthukisa ukusebenza kwemikhiqizo esekwe ku-clement kanye ne-gypsum. Phakathi kwazo, i-Hydroxypropyl Methylcellulose (HPMC) ingenye yezipho ezibaluleke kakhulu ze-celluLose Telloty.
Njengomenzi we-HPMC ongochwepheshe, sizokuchazela iqhaza le-Cellulose Ether ngesi-Putty. Siyethemba ukuthi lokhu okuthunyelwe kuhlinzeka ngokuqonda okusebenzayo kwalabo abanentshisekelo kulesi sihloko.
1. Ukugcinwa kwamanzi
Eminye yemisebenzi esemqoka ye-cellulose ether ye-putty ukugcinwa kwamanzi. I-PuTTY iyinto enjengezinto ezifana ne-paste ezisetshenziselwa ukugcwalisa izikhala nemifantu ezindaweni eziphakemeyo njengezindonga, ophahleni nasezitezi. Amanzi ayisithako esibalulekile ekwakhiweni kwama-tutty ngoba kusiza ukuncibilikisa izithako futhi kuhlinzeka ngokusebenza. Kodwa-ke, amanzi amaningi angadala ukuthi i-putty yomile futhi ihlehlise ngokushesha, okuholela ekuqhekekeni kanye nokuqedwa kwekhwalithi ephansi.
I-Cellulose Ether, ikakhulukazi i-HPMC, yakha isakhiwo esinjengejeli lapho sixutshwe namanzi, esingathuthukisa ukugcinwa kwamanzi kwesiphanzi. Amaqembu we-hpdrophilic akwa-HPMC angadonsa ama-molecule wamanzi futhi awavimbele ekuhwamukeni ngokushesha okukhulu. Lesi sici sivumela izikhathi zokusebenza ezinde nokuthungwa okuguqukayo ngokwengeziwe.
2. Thuthukisa ukusebenza
Omunye umsebenzi obalulekile we-cellulose ether ye-putty ukuthuthukisa ukusebenziseka kwawo. Ukusebenza kubhekisele kalula lapho iputty isetshenziswa futhi ibunjiwe ukuthola indawo ebushelelezi. I-Celsulose Ether ingathuthukisa ububi nokusakazeka kwe-putty ngokunciphisa ukungqubuzana phakathi kwezinhlayiya kanye nokwandisa ukuthambisa kohlelo.
Ukungezwa kwe-cellulose izithatheketha ama-tutties nakho kunciphisa ukufakwa komoya okubangelwa ukuxubeka, okungaholela ezindaweni ezingalingani kanye nokunamathelisa okumpofu. Ukusetshenziswa kwe-cellulose, izivumelwano kuthuthukisa ubushelelezi kanye nokuvumelana kwesipuni, okuholela ekusebenzeni okungcono okuphelele kanye nokuqedwa okukhangayo.
3. Khulisa ukunamathela
Enye inzuzo ye-cellulose ether ye-putty yenyuka nokunamathela. Amabhoti asetshenziselwa ukugcwalisa izikhala nemifantu, kanye nokwakha indawo ebushelelezi ngopende noma eminye imiphetho. Ngakho-ke, i-putty kumele ikwazi ukunamathela engxenyeni engezansi futhi inikeze isibopho esiqinile.
I-Cellulose Ether, ikakhulukazi i-HPMC, ingathuthukisa ukunamathela kwe-putty ngokwakha ifilimu ebusweni be-substrate. Ifilimu lithuthukisa ukuxhumana phakathi kwesipuni kanye ne-substrate futhi kusiza ukugcwalisa okungahambi kahle komhlaba. Lokhu kuphumela ngesibopho esinamandla kanye nokuqedwa okuhlala isikhathi eside.
4. Yehlisa i-shrinkage
I-Shrinkage iyinkinga evamile nge-putty, ngoba ingaholela ekuqhekekeni kanye nokuqedwa kwekhwalithi ephansi. Abakwa-Cellulose Abathi basiza ukunciphisa ukuncipha kwe-putty ngokuthuthukisa ukugcinwa kwamanzi kanye nokusebenza kwe-putty. Amanzi avele kancane kancane, enikeza i-putty ukuthungwa okubushelelezi okusiza ukuvimbela ukuqhekeka kanye nemifantu ekwakheni ngesikhathi somiswa.
Ngaphezu kwalokho, i-cellulose ether inganciphisa futhi i-shrinkage yepulasitiki ye-putty, okungukuthi, i-shrinkage eyenzeka ngesikhathi sokuhlelwa kokuqala. Le mpahla ibaluleke kakhulu kuma-tetties okusesheke, ngoba isiza ukugcina ubuqotho bobuso bese livimbela ukwakheka kwemifantu.
5. Ukuqina okuthuthukisiwe
Ekugcineni, ama-surlulose afers angathuthukisa ukuqina kwe-putty ngokuthuthukisa ukumelana kwayo ezintweni zezemvelo ezinjengoshintsho lokushisa, umswakama kanye nokuhlukunyezwa. Izakhiwo ezenziwe ngefilimu ze-cellulose ether zinganikeza isithiyo esivikelayo endaweni ebeka phezulu ukuvikela ukungena kwamanzi kanye nokunye ukungcola.
Ngaphezu kwalokho, i-cellulose ether ingathuthukisa namandla aguqukayo kanye nokumelana nomthelela we-putty, okwenza kube ukumelana nokuqhekeka nokushaywa. Le mpahla ibaluleke kakhulu kwizicelo lapho ama-tupties aphathwa khona noma athathwe khona, njengokusebenza kokulungisa noma ukuqedwa kokuhlobisa.
Ekuphetheni
Ekuphetheni, i-Cellulose Tasher, ikakhulukazi i-HPMC, iyindlela ebalulekile yokusebenza okuthuthukisayo. Imisebenzi yabo ifaka ukugcinwa kwamanzi, ukucutshungulwa okuthuthukile, ukunamathela okwandayo, ukuncishiswa kwe-shrinkage kanye nokuqina okuthuthukile. Kusetshenziswa izipho ze-cellulose afers kusiza ukuthuthukisa ikhwalithi ephelele nokusebenza kwe-putty, okuholela ekuqedeni okungcono nokuphila okude. Njengomenzi we-HPMC ongochwepheshe, sizibophezele ekuhlinzekeni amakhasimende ngekhwalithi ephezulu ye-cellulose ether kanye nokuxhaswa kwezobuchwepheshe.
