IHydroxypropylmethylcellulose (HPMC) iyi-polymer eguquguqukayo esetshenziswa ezinhlobonhlobo zezimboni.Izakhiwo zayo ziyenza ibe yinto ebalulekile, ikakhulukazi ekwakhiweni.I-HPMC inikeza uhla lwezinzuzo ezihlanganisa ukugcinwa kwamanzi okuthuthukisiwe, ukumuncwa kwamanzi okuncishisiwe kanye nokuqhubekela phambili okuthuthukisiwe.Lesi sihloko sigqamisa izinzuzo zokusebenzisa i-HPMC yebanga lezakhiwo ukukhulisa ukugcinwa kwamanzi ezindongeni ngenkathi kunciphisa ukumuncwa kwamanzi.
ukwandisa ukugcinwa kwamanzi
Enye yezinzuzo eziyinhloko zokusebenzisa i-HPMC ekwakheni yikhono layo lokwandisa ukugcinwa kwamanzi.Uma yengezwe kusimende noma ku-gypsum, i-HPMC yenza isakhiwo senethiwekhi esivale amanzi ngaphakathi.Lokhu kusiza ukugcina i-stucco ingabomi futhi iqine, kwelule inqubo yokwelapha.Ukwengeza, i-HPMC ihlinzeka ngokusebenza okungcono kwezinsimbi, okubalulekile kumaphrojekthi amasha wokwakha noma okulungisa.
Emasikeni avamile, amanzi ayahwamuka ngokushesha, okwenza kube nzima ukuwaxuba ngokulinganayo.Lokhu kungaholela ezindaweni ezibuthakathaka ekwakhiweni kokugcina ngisho nokuqhekeka ngaphambi kwesikhathi.Uma i-HPMC yengezwa engxubeni, ukugcinwa kwamanzi kungcono, kuqinisekisa ukufana nokuvumelana kwengxube.Lokhu kuthuthukisa ikhwalithi yohlelo lokusebenza, kuthuthukisa ukunamathela ku-substrate, futhi kunikeza ukulawula okungcono ngesikhathi sokwelapha.
ukunciphisa ukumuncwa kwamanzi
Enye inzuzo yokusebenzisa i-HPMC ukuthi inganciphisa kakhulu ukumuncwa kwamanzi odongeni.I-stucco yangaphandle kanye ne-stucco yizinto ezinezimbobo ezilungele ukulawula izinga lomoya wasendlini, kodwa futhi zijwayele ukumuncwa umswakama.Lapho izindonga zimunca amanzi, ziba lula ekulimaleni ngoba umswakama wenza i-stucco ibe buthaka, ibangele ukuqhekeka nokubhidlika.
Ngenhlanhla, i-HPMC inganciphisa izinga lokumuncwa kwamanzi odongeni.Ngokumboza ungqimba lwangaphandle lodonga ngongqimba oluncane lwe-HPMC, lwakha umgoqo wokuvikela ngokumelene nokungena komswakama.Lokhu kusiza ukuvimbela amanzi ukuthi angangeni ezindongeni, ukunciphisa ingozi yokulimala ngokuhamba kwesikhathi.
ukugcinwa kwamanzi okuhle
I-HPMC inezinto ezinhle kakhulu zokugcina amanzi, okuwusizo futhi emsebenzini wokwakha kanye nemikhiqizo yokugcina.Kubalulekile ukuthi ochwepheshe abasebenza kwezokwakha babe nokulawula okuhle ezintweni zabo namathuluzi.I-HPMC iqinisekisa umswakama olinganiselayo futhi olawulwa ngokunembile ku-stucco, ukhonkolo noma udaka, okuholela ekwelapheni okufanayo.
Ukugcinwa kahle kwamanzi kusho ukuthi ukhonkolo noma ukhonkolo kuzohlangana kahle ne-substrate.Ingxube ihlala inomswakama isikhathi eside, ivumela izithako ukuthi zihlanganyele kangcono futhi zakhe isibopho esiqinile.Isibopho esingcono siqinisekisa ukwakheka kodonga oluqinile, ngisho nasezimweni ezinzima.
Ekuphetheni
I-HPMC iyimpahla ebalulekile embonini yezokwakha.Izinzuzo zayo ekwandiseni ukugcinwa kwamanzi, ekwehliseni ukumuncwa kwamanzi, kanye nokuthuthukisa ukusebenza kahle zikwenza kube yinto okufanele ube nayo kunoma iyiphi iphrojekthi yokwakha noma yokulungisa.Ukusetshenziswa kwebanga lezakhiwo ze-HPMC kunganciphisa kakhulu ukumuncwa kwamanzi odongeni kuyilapho kunezindawo ezinhle zokugcina amanzi.I-HPMC iwumsebenzi obalulekile oyinzuzo kochwepheshe bokwakha, ibasiza ukuthi bakhiqize izindonga nezakhiwo eziqinile, ezisezingeni eliphezulu.
