I-HPMC (HYDROXYPROPYLCELLELLELLELLELLelLellulose) iyi-cellulose derivative esetshenziswa kakhulu ezintweni zokwakha, ikakhulukazi ama-clement noma ama-gypsum asuselwa ku-gypsum kanye nama-plasters. Kuyinto eyengeziwe eyengeziwe ethuthukisa ukusebenza kwalezi zinto zokwakha futhi ithuthukise izakhiwo zayo. I-HPMC iyi-polymer encibilikayo yamanzi engahlakazeka kalula emanzini ukuze wakhe isixazululo esiminyene, esinobunzima.
Kulesi sihloko, sihlola izinzuzo ezahlukahlukene zokusebenzisa i-HPMC ku-Cement noma ama-Gypsum asuselwa ku-Plasters kanye nama-Plasters.
Thuthukisa ukusebenza
Enye yezinzuzo eziphambili zokusebenzisa i-HPMC ku-Cement noma ama-Gypsum asuselwa ku-GypSum kanye nabahlengi bawo ukusebenza kwawo okuthuthukile. Ukucekelwa phansi kubhekiselwa kalula lapho okuqukethwe kungaxutshwa khona, kusetshenziswe futhi kusetshenzwe. I-HPMC isebenza njengokugcoba, ithuthukisa ukugeleza nokusakazeka kwezinto ezibonakalayo, okwenza kube lula ukufaka isicelo kanye nokuqeda okubushelelezi.
Ukuba khona kwe-HPMC ekuhlanganiseni nakho kunciphisa ukufunwa kwamanzi okubonakalayo, okusiza ukulawula ukushwabana nokuqhekeka ngesikhathi sokomiswa. Lokhu kusho ukuthi okuqukethwe kuzogcina ukwakheka nosayizi wayo futhi ngeke kuqhekeze noma kunciphiswe ngenxa yokulahleka komswakama.
Thuthukisa ukunamathela
I-HPMC nayo ingathuthukisa ukunamathela nokuhunyushwa kwama-clemende noma ama-gypsum asuselwa ku-Gypsum kuze kube ngaphezulu kwesisekelo. Lokhu kungenxa yokuthi i-HPMC yakha ifilimu elincanyana ebusweni be-substrate esebenza njengesithiyo somswakama futhi ivimbele udaka kusuka ekutholeni noma ekuhlukaniseni okuphansi.
Ifilimu eyakhiwa yi-HPMC futhi ithuthukisa isibopho sodaka esihlokweni se-substrate ngokwakha uphawu oluqinile phakathi kwalokhu okubili. Lokhu kwandisa amandla jikelele nokuqina kodaka, okwenza kube mancane amathuba okuthi kuqhekeke noma kukhubeke.
Thuthukisa ukumelana kwesimo sezulu
Ama-Plasters asuselwa kasimende noma we-gypsum kanye nama-plasters aqukethe i-HPMC amelana kakhulu nesimo sezulu kanye nokuguguleka. Lokhu kungenxa yokuthi i-HPMC yakha ifilimu evikelayo ebusweni bodaka olukhipha amanzi futhi livimbela umswakama ekungeneni kokuqukethwe.
Ifilimu eyakhiwa yi-HPMC futhi yenza i-gppsum imelane kakhulu nemisebe ye-UV nezinye izinhlobo zezimo sezulu, ikuvikele kumonakalo odalwe yilanga, umoya, imvula kanye nezinye izinto zemvelo.
Ukuqina okukhulayo
Ukungeza i-HPMC kuya kumasimende noma ama-gypsum asuselwa ku-gypsum kanye nama-plasters kuthuthukisa ukuqina kwawo jikelele. Lokhu kungenxa yokuthi i-HPMC inyusa ukuguquguquka nokuqina kodaka, okwenza kube mancane amathuba okuba nokuqhekeka noma ukuphula. I-HPMC ibuye yandisa ukugqokwa kanye nokumelana nomthelela walokho okuqukethwe, okwenza kube ukumelana nokuhlukumezeka.
Ukuqina okukhulayo kwezinto ezibonakalayo nakho kwenza kube ukumelana nokulimala kwamanzi okufana nokungena kwamanzi, okumanzi kanye nokukhula kobumba. Lokhu kwenza kube yinto efanelekile yokusebenzisa ezindaweni ezimanzi njengokugeza, amakhishi kanye namakamelo okuphansi.
Thuthukisa ukumelana nomlilo
Ama-Plasters asuselwa ku-CENT- noma ama-gypsum asuselwa ku-HPMC aqukethe i-refracting ukwedlula lawo angenayo i-HPMC. Lokhu kungenxa yokuthi i-HPMC yakha ungqimba oluvikelayo ebusweni bodaka olusiza ukuvimba ukuthi kunganaki noma kusakaze ilangabi.
Ukuba khona kwe-HPMC engxube futhi kuthuthukisa izindawo zokufaka okushisayo kodaka. Lokhu kusiza ukuvikela ukushisa ekungeniseni udaka, olungasiza ukunciphisa ukusakazeka komlilo.
Ekuphetheni
I-HPMC isengezo esisebenzayo esisetshenziswa kabanzi ezintweni zokwakha, ikakhulukazi ama-clemende noma ama-gypsum asuselwa ku-gypsum kanye nama-plasters. Inikeza inzuzo yezinzuzo kufaka phakathi ukucubungula okuthuthukile, ukunamathela okuthuthukile, isimo sezulu esithuthukisiwe, ukuqina okuthuthukile kanye nokuphikiswa komlilo okuthuthukile.
Usebenzisa i-HPMC ku-Cement- noma ama-gypsum asuselwa kuma-gypsum futhi ama-plasters angasiza ekuthuthukiseni ukusebenza nokuphila isikhathi eside kwalezi zinto zokwakha, abenze bamelane nokugqoka kanye nezinto. Ilungele osonkontileka kanye nabakhi abafuna ukuqinisekisa ikhwalithi nokuqina kwephrojekthi eqediwe.
