IHydroxypropylmethylcellulose (HPMC) yipolymer esetyenziswa ngeendlela ezininzi kwiintlobo ngeentlobo zamashishini.Iimpawu zayo zenza ukuba ibe yinto exabisekileyo, ngakumbi ekwakhiweni.I-HPMC ibonelela ngoluhlu lweenzuzo ezibandakanya ukugcinwa kwamanzi okuphuculweyo, ukufunxwa kwamanzi okucuthiweyo kunye nokuqhubekeka okuphuculweyo.Eli nqaku ligxininisa iinzuzo zokusebenzisa ibakala lokwakha i-HPMC ukunyusa ukugcinwa kwamanzi ezindongeni ngelixa kuncitshiswa ukufunxa kwamanzi.
ukwandisa ukugcinwa kwamanzi
Enye yeenzuzo eziphambili zokusebenzisa i-HPMC kulwakhiwo kukukwazi ukunyusa ukugcinwa kwamanzi.Xa idityaniswe kwisamente okanye igypsum, i-HPMC yenza ulwakhiwo lothungelwano oluthi luvale amanzi ngaphakathi.Oku kunceda ukugcina i-stucco ekumisweni nasekuqineni, ukwandisa inkqubo yokunyanga.Ukongeza, i-HPMC ibonelela ngokusebenza ngcono kwiidaka, ezibaluleke kakhulu kulwakhiwo olutsha okanye iiprojekthi zokulungisa.
Kwiidaka eziqhelekileyo, amanzi aphuphuma ngokukhawuleza, okwenza kube nzima ukuxuba ngokulinganayo.Oku kunokukhokelela kwiindawo ezibuthathaka kulwakhiwo lokugqibela kunye nokuqhekeka kwangaphambi kwexesha.Xa i-HPMC yongezwa kumxube, ukugcinwa kwamanzi kungcono, ukuqinisekisa ukufana kunye nokuhambelana komxube.Oku kuphucula umgangatho wesicelo, kuphucula ukunamathela kwi-substrate, kwaye kunika ulawulo olungcono kwixesha lokunyanga.
ukunciphisa ukufunxwa kwamanzi
Enye inzuzo yokusebenzisa i-HPMC kukuba inokunciphisa kakhulu ukufunxa kwamanzi eludongeni.I-stucco yangaphandle kunye ne-stucco zizixhobo ezivuzayo ezilungele ulawulo lomgangatho womoya wangaphakathi, kodwa zikwathanda ukufunxa ukufuma.Xa iindonga zifunxa amanzi, ziba sesichengeni sokonakala kuba ukufuma zenza buthathaka i-stucco, nto leyo ebangela ukuba siqhekeke size siphuke.
Ngethamsanqa, i-HPMC inokunciphisa izinga lokufunxa kwamanzi eludongeni.Ngokugquma umaleko wangaphandle eludongeni kunye umaleko obhityileyo we-HPMC, idala umqobo okhuselayo ekungeneni kokufuma.Oku kunceda ukukhusela amanzi ekungeneni kwiindonga, ukunciphisa umngcipheko womonakalo ekuhambeni kwexesha.
ukugcinwa kakuhle kwamanzi
I-HPMC ineempawu ezigqwesileyo zokugcina amanzi, eziluncedo kumsebenzi wokwakha kunye neemveliso zokuphela.Kubalulekile ukuba iingcali ezisebenza kumsebenzi wokwakha zibe nolawulo olufanelekileyo kwizinto nezixhobo zazo.I-HPMC iqinisekisa ukufuma okulinganayo kunye nokulawulwa ngokuchanekileyo kwi-stucco, udaka okanye udaka, okukhokelela ekunyangeni okufanayo.
Ukugcinwa kakuhle kwamanzi kuthetha ukuba udaka okanye udaka luya kudibanisa kakuhle kwi-substrate.Umxube uhlala ufumile ixesha elide, ukuvumela izithako ukusebenzisana ngcono kwaye zenze ibhondi eyomeleleyo.Ukudibanisa okungcono kuqinisekisa ukwakhiwa kodonga oluzinzileyo, nakwiindawo ezinzima.
ukuququmbela
I-HPMC sisixhobo esibalulekileyo kushishino lokwakha.Izibonelelo zayo ekwandiseni ukugcinwa kwamanzi, ukunciphisa ukufunxa kwamanzi, kunye nokuphucula ukusebenza kakuhle kwenza kube yinto efunekayo kuyo nayiphi na iprojekthi yokwakha okanye ukulungiswa.Ukusetyenziswa kwebakala loyilo lwe-HPMC kunokunciphisa kakhulu ukufunxa kwamanzi eludongeni ngelixa uneempawu ezilungileyo zokugcina amanzi.I-HPMC sisixhobo esixabisekileyo esisisixhobo sokwakha iingcali, ukubanceda ukuba bavelise eyomeleleyo, iindonga ezikumgangatho ophezulu kunye nezakhiwo.
