Iyini i-HPMC yodaka oluxutshwe okomile?

1. Incazelo ye-HPMC
I-HPMC (i-Hydroxypropyl Methyl Cellulose)iyi-non-ionic cellulose ether esetshenziswa kabanzi ezintweni zokwakha, kwezokwelapha, ekudleni, kumakhemikhali ansuku zonke nakwezinye izimboni. Ku-mortar exutshwe okomile, i-AnxinCel®HPMC isetshenziswa kakhulu njengesithambisi, i-ejenti yokugcina amanzi kanye ne-modifier, engathuthukisa kakhulu ukusebenza kokwakhiwa kwe-mortar.

2. Indima ye-HPMC ku-mortar exutshwe okomile

Imisebenzi eyinhloko ye-HPMC ku-dry-mixed mortar yilena elandelayo:

Ukugcinwa kwamanzi: I-HPMC ingamunca amanzi futhi ivuvuke, yakhe ifilimu yokumunca amanzi ngaphakathi kwe-mortar, inciphise ukuhwamuka kwamanzi ngokushesha, ithuthukise ukusebenza kahle kokumunca amanzi kwesamente noma i-gypsum, futhi ivimbele ukuqhekeka noma ukulahleka kwamandla okubangelwa ukulahleka kwamanzi ngokweqile.

Ukuqina: I-HPMC inikeza i-thixotropy enhle ye-mortar, okwenza i-mortar ibe nokugeleza okufanele kanye nezakhiwo zokwakha, futhi igweme ukuvuza kwamanzi kanye nokuchitheka kwamanzi okubangelwa ukuhlukaniswa kwamanzi.

Thuthukisa ukusebenza kokwakhiwa: I-HPMC ithuthukisa ukugcotshwa kwe-mortar, okwenza kube lula ukuyisebenzisa nokukala, ngenkathi ithuthukisa ukunamathela kwi-substrate futhi inciphisa ukuqhuma kwe-powdery kanye nokugoba.

Nweba isikhathi sokuvula: I-AnxinCel®HPMC inganciphisa izinga lokuhwamuka kwamanzi, yandise isikhathi esisebenzayo se-mortar, yenze ukwakhiwa kube lula, futhi ifaneleka kakhulu ezindaweni zokusetshenziswa ezinkulu kanye nezindawo zokwakha ezishisa kakhulu.

Ukungagugi: Ezintweni zokwakha eziqondile njengezinamathiseli zethayela nama-putty, i-HPMC ingavimbela izinto ukuthi zingasheleli phansi ngenxa yesisindo sayo futhi ithuthukise ukuzinza kokwakhiwa.

3. Ukusetshenziswa kwe-HPMC ezitsheni ezahlukene ezixutshwe kahle

I-HPMC isetshenziswa kabanzi ezinhlotsheni ezahlukene zezimbotshana ezixutshwe okomile, okuhlanganisa kodwa kungagcini lapho:

Udaka lokubumba kanye nodaka lokuplasta: kuthuthukisa ukugcinwa kwamanzi, kuvimbela ukuqhekeka kodaka, futhi kuthuthukisa ukunamathela.

I-adhesive yethayela: thuthukisa ukunamathela, thuthukisa ukusebenziseka kalula kokwakhiwa, futhi uvimbele amathayela ukuthi angasheleli.

Udaka oluzilinganisayo: luthuthukisa ukugeleza kwamanzi, luvimbele ukuhlukaniswa, futhi luthuthukise amandla.

Udaka olungangeni manzi: kuthuthukisa ukusebenza okungangeni manzi futhi kwandise ubuningi bodaka.

Impuphu ye-putty: ithuthukisa ukusebenza kokwakhiwa, ithuthukisa ukumelana nokukhuhla, futhi ivimbele ukuphotha.

4. Ukukhetha kanye nokusetshenziswa kwezinyathelo zokuphepha ze-HPMC

Imikhiqizo ehlukene yodaka inezidingo ezahlukene ze-HPMC, ngakho-ke izici ezilandelayo zidinga ukucatshangelwa lapho ukhetha:

Ukujiya: I-AnxinCel®HPMC ene-viscosity ephansi ifaneleka ku-mortar yokuzilinganisa ene-fluidity enhle, kanti i-HPMC ene-viscosity ephezulu ifaneleka ku-putty noma ku-tile adhesive enamanzi amaningi.izidingo zokugcina.

Ukuncibilika: I-HPMC esezingeni eliphezulu kufanele ibe nokuncibilika okuhle, ikwazi ukuhlakazeka ngokushesha futhi yakhe isixazululo esifanayo ngaphandle kokuhlanganiswa noma ukuhlanganiswa.
Inani lokwengeza: Ngokuvamile, inani lokwengeza le-HPMC ku-mortar exutshwe okomile lingu-0.1% ~ 0.5%, futhi isilinganiso esithile sidinga ukulungiswa ngokuya ngezidingo zokusebenza ze-mortar.

I-HPMCiyisengezo esibalulekile ku-mortar exutshwe okomile, okungathuthukisa ukusebenza kokwakhiwa, ukugcinwa kwamanzi kanye nokunamathela ko-mortar. Isetshenziswa kabanzi ku-mortar yobumba, i-plastering mortar, i-tile adhesive, i-putty neminye imikhiqizo. Uma ukhetha i-HPMC, kubalulekile ukulinganisa i-viscosity efanele kanye nefomula ngokwesimo esithile sokusetshenziswa ukuqinisekisa umphumela omuhle kakhulu wokwakha.
