I-Skim coating iyindlela ethandwayo yokuthola indawo ebushelelezi, elinganayo ezindongeni nakusilingi.Indlela yokwenza ihlanganisa ukusebenzisa ungqimba oluncane lodaka noma i-stucco endaweni emagebhugebhu noma engalingani ukuze udale isisekelo seleveli sopende noma iphepha lodonga.I-HPMC noma i-hydroxypropyl methylcellulose iwugqinsi oluvame ukusetshenziswa ezingxubeni zongqimba oluncane.Ake sihlolisise izinzuzo ze-HPMC ngezendlalelo ezincane.
Okokuqala, i-HPMC iyi-thickener enhle kakhulu ye-putty ngoba iyancibilika emanzini futhi kulula ukuyixuba.Ngokungafani nezinye izingqimba ezifana nesitashi se-tapioca noma ufulawa kakolweni, i-HPMC incibilika ngokuphelele emanzini, okwenza kube lula ukuzuza ukuthungwa okungaguquki kuzingxube zokugwedla.Ngaphezu kwalokho, i-HPMC inokunamathela okuhle kakhulu, okusiza i-putty ukunamathela ku-substrate futhi ivimbele ukuqhekeka.
Enye inzuzo ebalulekile yokusebenzisa i-HPMC ezixubeni zokuhlanganisa i-putty yikhono layo lokuthuthukisa ukucutshungulwa nokugeleza.Ngenxa yokuthi i-HPMC ishubisa kancane kancane ingxube, inika u-plaster isikhathi esengeziwe sokusebenza ezingqimbeni ze-putty ngaphambi kokuthi izithe.Ngokulandelayo, lokhu kuvumela uhlelo lokusebenza olubushelelezi, olulinganayo.Ngaphezu kwalokho, i-HPMC ithuthukisa izici zokulinganisa ze-putty, ivumela ukuthi ikwazi ukuzilinganisa futhi igcwalise ukungapheleli okuncane ku-substrate.
I-HPMC futhi iyinketho evumelana nemvelo yokwakheka kongqimba oluncane.Njengomkhiqizo we-cellulose, i-biodegradable futhi ayinabuthi.Lokhu kusho ukuthi i-HPMC ayinayo imithelela eyingozi emvelweni noma empilweni yomuntu.Ukwengeza, i-HPMC ithuthukisa ukusimama ngokunciphisa imfucuza futhi igweme ukulungiswa ngokweqile noma ukushintshwa.
Ekugcineni, i-HPMC iyonga futhi itholakala kabanzi.Ikhiqizwa ngobuningi futhi idayiswa ezimakethe zomhlaba, okwenza ifinyeleleke kubo bobabili abakhiqizi kanye nabasebenzisi bokugcina.I-HPMC iphinde ibe nempilo yeshelufu ende, okusho ukuthi ingagcinwa isikhathi eside ngaphandle kokulahlekelwa ikhwalithi yayo noma ukusebenza kahle kwayo.
Sengiphetha, i-HPMC iyi-thickener enhle kakhulu yezingxube ze-putty coating.Inikeza izinzuzo eziningi ezihlanganisa ukucutshungulwa okuthuthukisiwe, ukugeleza, izinga nokunamathela.Ngaphezu kwalokho, ihambisana nemvelo, iyabiza futhi inezinhlobonhlobo zezinhlelo zokusebenza.Ngakho-ke, i-HPMC iyinketho ethandwayo kubo bobabili abapulasi abanolwazi nabanolwazi abafuna ukuzuza ubushelelezi, ngisho nendawo ezindongeni nakusilingi.
