Izembatho ze-HPMC ziya ngokuya zithandwa emkhakheni wokumboza ngenxa yobungane bazo bemvelo, ukucubungula kalula, ukunamathela okuhle, kanye nezakhiwo ezinhle kakhulu zokwenza ifilimu. Kodwa-ke, njenganoma yikuphi ukunamathela, ukusetshenziswa kwezingubo ze-HPMC kudinga izithasiselo ezithile ukusiza ukufeza izakhiwo ezifiselekayo, kufaka phakathi ama-disperants kanye nama-thickeners.
Iziphazamisi ziyizithasiselo ezibalulekile zezingubo ze-HPMC ngoba zivimbela izinhlayiya noma i-pigment agglomeration, engase ibeke engcupheni ikhwalithi yefilimu, iphazamise inqubo yokumboza, futhi yehlise ukusebenza kokumboza. Umsebenzi we-dispersant ukukhangisa ebusweni bezinhlayiya ukuze kwakhiwe ungqimba oluvikelayo oluxosha ngogesi ezinye izinhlayiya futhi lizivimbele ukuthi zingahlangani. Izembatho ze-HPMC zivame ukusebenzisa ama-polymer dispersants, anenzuzo yokungavimbeli kuphela ukuhlaliswa kwezinhlayiyana, kodwa futhi nokunciphisa i-viscosity ye-slurry, ithuthukise ukuguquguquka kwayo nokufana kokugqoka.
Ama-thickeners, ngakolunye uhlangothi, adlala indima ebalulekile ekuthuthukiseni i-viscosity kanye nezakhiwo ze-rheological zezingubo ze-HPMC. I-thickener enhle kufanele ibe nesisindo samangqamuzana aphezulu kanye nokuncibilika kwamanzi okuhle ukuze kuqinisekiswe ukufakwa kalula nokuhlakazeka ku-matrix kapende. Ama-thickeners akhulisa i-viscosity futhi akhiqize ukucindezeleka kwe-coating, okuvumela ukuthi unamathele kangcono endaweni futhi yakhe ifilimu ebushelelezi, efanayo. Ngaphezu kwalokho, ama-thickeners athuthukisa ukulawulwa kwe-rheology ye-coating, okwenza kube lula ukusebenzisa nokusebenzisa izindlela ezahlukene zokufaka isicelo.
Inhlanganisela yama-dispersants nama-thickeners ingathuthukisa kakhulu ukusebenza kanye nekhwalithi yezingubo ze-HPMC ngokuthuthukisa ukuhlakazeka kwazo kanye ne-viscosity. Ngaphezu kwalokho, ukwakheka okuklanywe ngokucophelela kungathuthukisa ukuzinza, ukuthuthukiswa kombala kanye nokumelana nesimo sezulu kwezingubo. Ama-dispersers afanelekile kanye nama-thickeners kufanele akhethwe ngokusekelwe ezidingweni ezithile zokufaka isicelo sokumboza, njenge-substrate surface, ukujiya kokugqoka, indlela yokufaka isicelo kanye nemvelo yokusetshenziswa kokugcina.
Phakathi kwama-dispersants kanye nama-thickeners angasetshenziswa embotsheni ye-HPMC, okuphuma ku-cellulose bathole ukunakwa okubanzi ngenxa yokuhambisana kwabo okuhle ne-HPMC kanye nemithethonqubo yezemvelo embonini yokuhlanganisa. Isibonelo, i-carboxymethyl cellulose (CMC) ingahlakaza futhi imise ama-pigments kuma-HPMC ngenkathi ithuthukisa i-rheology yabo nokusabalalisa usayizi wezinhlayiyana. Ngokunjalo, i-methylcellulose (MC) iwugqinsi osetshenziswa kakhulu ezimbotsheni ze-HPMC ngenxa yekhono layo lokwenza inethiwekhi yejeli eqinile futhi igcine i-viscosity ezinzile phezu kwe-pH ebanzi nebanga lokushisa.
Enye inzuzo yokusebenzisa okuphuma ku-cellulose njengama-dispersants kanye nama-thickeners embotsheni ye-HPMC ukuthi ayinabo ubuthi, i-biodegradable futhi ivuseleleka, inciphisa umthelela wazo wemvelo ngesikhathi sokukhiqiza, ukusetshenziswa nokulahlwa. Ukwengeza, izici eziyingqayizivele zomzimba namakhemikhali zokuphuma kokuphuma ku-cellulose nazo zingadlulisela izici ezithile embotsheni ye-HPMC, njengokugcina amanzi, ukuthambisa kanye namandla okwenza ifilimu.
Ama-disperants kanye nama-thickeners ayizithasiselo ezibalulekile embotsheni ye-HPMC ukuze kuqinisekiswe ukuhlakazeka okuhle, i-viscosity kanye nokusebenza. Ngokukhetha ngokucophelela kanye nokwakhiwa kwama-dispers kanye nama-thickeners afanelekile, ukusebenza kanye nekhwalithi yezingubo ze-HPMC zingathuthukiswa, okuholela ekusebenzeni kahle kokugqoka, ukunamathela nokuqina. Ngaphezu kwalokho, ukusetshenziswa kwezinto eziphuma ku-cellulose ezinobungani bemvelo nezivuselelekayo njengama-dispersants kanye nama-thickeners kusiza ukunciphisa umthelela wemvelo wezingubo ze-HPMC ngenkathi kuthuthukiswa ukusebenza nokusebenza kwazo.
I-HPMC Hydroxypropyl Tile Adhesive Cement Mix
IHydroxypropyl methylcellulose, eyaziwa nangokuthi i-HPMC, iphuma ku-cellulose evame ukusetshenziswa embonini yezokwakha, ikakhulukazi ekukhiqizeni izinto zokunamathisela zamathayili nezingxube zikasimende. Kungumkhiqizo oguquguqukayo ongasetshenziswa kuzinhlelo zokusebenza ezihlukene futhi unikeza uhla lwezinzuzo eziwenza ube isithako esikahle sezinhlobo eziningi ezahlukene zezinto zokwakha.
Enye yezinzuzo eziyinhloko ze-HPMC yikhono layo lokuthuthukisa ukusebenza nokuvumelana kwezingxube zikasimende nezokunamathela zamathayela.
