I-HPMC (ihydroxypropyl methylcellulose) sisixhobo sekhemikhali esisebenza ngeendlela ezininzi esisetyenziswa kakhulu kulwakhiwo nakwamanye amasimi oshishino. Yi-ether ye-cellulose engeyo-ionic eyenziwe kwi-cellulose yendalo eguqulwe ngamachiza. I-HPMC inemisebenzi eyahlukeneyo efana nokutyeba, ukugcinwa kwamanzi, ukubunjwa kwefilimu, ukuthambisa, kunye nokunamathela, ukuyinika amandla okusebenza ngokubanzi kushishino lokwakha.
1. Umsebenzi ophambili we-HPMC kwizicelo zokwakha
(1) Ukuqina kwesiphumo
Xa HPMC inyibilika emanzini, oko kunokwandisa kakhulu viscosity ulwelo. Esi siphumo sokuqina sibaluleke kakhulu kwizinto zokwakha. Ngokomzekelo, kwi-cement mortar, i-HPMC inokuphucula i-viscosity yodaka, iphucule ukukhululeka kokwakhiwa, kwaye yenze ukwakhiwa kube lula.
(2) Ukugcinwa kwamanzi
I-HPMC ineempawu ezigqwesileyo zokugcina amanzi, nto leyo eyenza ukuba amanzi abe ngumphunga kwiimeko ezomileyo. Oku kubaluleke kakhulu kwizinto ezisekelwe kwisamente ukuthintela udaka okanye ikhonkrithi ukuba yome okanye ilahlekelwe ngamandla ngenxa yokulahlekelwa ngokukhawuleza kokufuma ngaphambi kokumiswa. Ukongezelela, ukugcinwa kwamanzi kunokuphucula ixesha lokuvula i-adhesives kunye ne-putty powder, ukunika abasebenzi bokwakha ixesha elingakumbi lokulungelelanisa.
(3) Ipropati ye-Anti-sag
Kulwakhiwo oluthe nkqo (okufana nokutyabeka eludongeni okanye ukufaka iithayile), i-HPMC inokuthintela ngokufanelekileyo izinto ekutyibilikeni ezantsi ngenxa yomxhuzulane. Inceda udaka okanye i-adhesive igcine ukubambelela kakuhle kwaye iqinisekisa ukwakhiwa kakuhle.
(4) Iipropati ezigqwesileyo zokwenza ifilimu
I-HPMC yenza ifilimu efanayo emva kokumisa, ipropathi yokwenza ifilimu ebaluleke kakhulu kwiingubo ezingenamanzi kunye nemigangatho yokuzimela. Ifilimu eyenziwe ngefilimu inokunyusa ukuchasana kwamanzi kunye nokuchasana kwemozulu yezinto.
(5) I-Lubrication kunye nemiphumo yokudibanisa
I-HPMC inokuphucula ukuthanjiswa kwezinto zokwakha, ukunciphisa ukukhuhlana ngexesha lokwakha, kwaye yenze izinto zisasazeke kakuhle kumphezulu we-substrate. Ukongeza, i-HPMC inokuphucula iipropathi zokudibanisa kunye nokuphucula amandla okudibanisa kwezinye izinto zokuncamathelisa.
2. Ukusetyenziswa kweHPMC kwiinkalo ezithile zokwakha
(1) Udaka olusekelwe kwisamente
Kwizitya zokutyabeka, iintsimbi zobumba, kunye nezixhobo zokuzilinganisa, i-HPMC inokuphucula ukugcinwa kwamanzi kunye nokuguquguquka kodaka, ngaloo ndlela iphucula ukusebenza kolwakhiwo kunye nomgangatho wokugqibela wokubumba. Ukongeza, ipropathi ye-anti-sag ye-HPMC iqinisekisa ukuba udaka aluyi kutyibilika lula xa lufakwe kwiindonga ezithe nkqo.
(2) I-adhesive tile ye-Ceramic
Iimfuno eziphambili ze-adhesive tile zinamandla okudibanisa kunye nokulula ukwakhiwa. I-HPMC kwi-adhesive tile ayikwazi nje ukuphucula ukubambelela kwe-colloid, kodwa yandisa ixesha lokuvula, ukuvumela abasebenzi bokwakha ukuba babe nexesha elide lohlengahlengiso, ngaloo ndlela baphucula ukusebenza kakuhle kolwakhiwo.
(3) Umgubo weputty
I-HPMC inika i-putty powder ukugcinwa kakuhle kwamanzi kunye nolwelo. Ngethuba lokwakhiwa kwe-putty, ukugcinwa kwamanzi kuthintela umgca wesiseko ekuthatheni amanzi ngokukhawuleza, uqinisekisa ukuba i-putty yomile ngokulinganayo, kwaye iyanciphisa umngcipheko wokuqhekeka nokuwa.
(4) Ukugquma kwamanzi
Iipropati zokwenza ifilimu ye-HPMC zifaneleke kakhulu kwiingubo ezingenamanzi. Inokunceda i-coating yenze umaleko oshinyeneyo kunye nofanayo ongangeni manzi kumphezulu we-substrate ukunyusa amandla okungena kwamanzi kwisakhiwo sokwakha.
(5) Iimveliso ezisekelwe kwiGypsum
Kwi-gypsum-based screeding kunye ne-plastering materials, i-HPMC ibonelela ngokugcinwa kwamanzi okulungileyo, ukukhusela i-gypsum ekulahlekelweni kwamandla ngenxa yokulahlekelwa ngumswakama obuninzi. Ngexesha elifanayo, umphumo walo wokuqina unokuphucula ukukhululeka kwesicelo.
