IHydroxypropylmethylcellulose (HPMC) iyisithako esisebenza ngezindlela eziningi esisetshenziswa kakhulu embonini yezokwakha.Kuyi-polymer ephilayo etholakala ku-cellulose futhi isetshenziswa njenge-thickener encibilikayo emanzini, i-binder kanye nefilimu yangaphambili.I-HPMC idlala indima ebalulekile ekwakhiweni kwe-putty powder engangeni emanzini, esetshenziswa kabanzi emkhakheni wokwakha.
I-putty powder engavimbeli amanzi iyisinamathiselo esetshenziswa ekwakhiweni kwesakhiwo ukuze kugcwaliswe izikhala, imifantu nezimbobo ezindongeni, usimende, ukhonkolo, i-stucco nezinye izindawo.Ngokuyinhloko isetshenziselwa ukwakha indawo ebushelelezi yokudweba, ukwenza iphepha lodonga noma ukufaka amathayela.I-putty powder engavimbeli amanzi ibhekwa kakhulu ngenxa yekhono layo lokumelana nomswakama, okwenza kube yinto okufanele ibe nayo yezindlu zokugezela, amakhishi nezinye izindawo ezimanzi.
Kunezinzuzo ezimbalwa zokusebenzisa i-HPMC kuma-putty powders amelana namanzi.
I-HPMC iyi-ejenti enhle kakhulu yokugcina amanzi, engathuthukisa ukusebenza kwesixosha amanzi esivame ukusetshenziswa ku-putty powder.Kuyasiza futhi ukuvimbela umswakama ekungeneni kwe-putty ukuze kuphele isikhathi eside, isikhathi eside.Ukwengeza, i-HPMC iyifilimu yangaphambili eyenza umgoqo wokuvikela phezu kwe-putty, ukuvimbela amanzi ukuthi angangeni futhi abangele umonakalo.
Enye inzuzo ye-HPMC ku-putty engavimbeli amanzi powder ukuthuthukisa amandla esibopho se-putty nokuthuthukisa ukunamathela kwayo ku-substrate.Lesi sakhiwo senza i-HPMC ibe isithako esibalulekile ekwakhiweni kwe-putty, iqinisekisa ukuthi i-putty inamathela ngokuqinile phezulu futhi ayiqhekeki noma idilike ngokuhamba kwesikhathi.Ngokungezwa kwe-HPMC, izimpushana ezingangeni emanzini ziba zizinze, ziqine futhi zibe lula ukuzisebenzisa, okuwenza abe yinketho edumile phakathi kochwepheshe bezokwakha.
Ngaphezu kwezindawo zayo zokunqanda amanzi, i-HPMC iphinde ibe nomthelela onenzuzo kumthelela wemvelo we-putty powders ukumelana namanzi.Imvelo yayo ebolayo iqinisekisa ukuthi i-putty ihambisana nemvelo futhi ayilimazi imvelo.I-HPMC futhi ayinabo ubuthi futhi ayikhiqizi intuthu eyingozi noma iphunga, ikwenze kuphephe ukusetshenziswa ezakhiweni nasezindlini.
Ukusetshenziswa kwe-hydroxypropyl methylcellulose (HPMC) kuma-putty powders angangeni emanzini kuyisithako esibalulekile embonini yezokwakha.Izakhiwo zayo ezivimbela amanzi kanye nokunamathela zenza kube isithako esihle kakhulu sama-putty, sinikeza isiphetho esihlala isikhathi eside, esiqinile esimelana nomswakama kanye nokugqoka kwemvelo.Futhi, iyabola futhi ayinabo ubuthi, okuyenza ibe enye indlela evumelana nemvelo ephephile ukuthi isetshenziswe ezindaweni zomphakathi.Ngokusebenzisa i-HPMC, singakha izakhiwo ezinokuqina okukhulu, ukuzinza nokusimama.
