Iyini i-HPMC yodaka oluxutshwe ngodaka?

1. Ukuchazwa kwe-HPMC
I-HPMC (HYDROXYPROPYL Methyl Cellulose)Ingabe i-ether engeyona eye-cellulose ether esetshenziswa kabanzi ezintweni zokwakha, umuthi, ukudla, amakhemikhali nsuku zonke nezinye izimboni. Udaka oluhlanganisiwe olomile, i-ComTinCHELXEXPPMC isetshenziswa ikakhulukazi njenge-persener, i-ejenti yokugcina amanzi kanye ne-modifier, engathuthukisa kakhulu ukusebenza kodaka ngodaka.

2. Iqhaza le-HPMC ngodaka oluhlanganisiwe olomile

Imisebenzi esemqoka ye-HPMC ku-data oxutshwe nodaka olumiswe kanjena:

Ukugcinwa kwamanzi: I-HPMC ingadonsa amanzi nokuvuvukala, yakha ifilimu ye-hydration ngaphakathi kodaka, kunciphisa ukusebenza kahle kwamanzi, ukuthuthukisa ukusebenza kahle kosimende noma i-gypsum, nokuvimbela ukuqhekeka noma ukulahleka kwamandla okubangelwa ukulahleka kwamanzi ngokweqile.

Ukuqina

Thuthukisa ukusebenza kokwakha

Nweba isikhathi esivulekile: ICicken®hppmc inganciphisa ijubane izinga lamanzi okuhwamuka, ukunweba isikhathi esisebenzayo sodaka, senze ukwakhiwa kube nezimo, futhi kufanelekile ikakhulukazi ukutholakala kwezindawo ezinkulu zendawo.

I-Anti-Sagging: Ezimweni zokwakha ezimile ezifana nezinamathelatha ze-tile nama-tutties, i-HPMC ingavimba impahla ukuthi ishelele phansi ngenxa yesisindo sayo futhi ithuthukise ukuqina kokwakha.

I-3. Ukusetshenziswa kwe-HPMC ku-mature ahlukene omile

I-HPMC isetshenziswa kabanzi ezinhlotsheni ezahlukahlukene zohlobo oluxubile, kufaka phakathi kepha kungakhawulelwe ku:

U-Masonry udaka nodaka oluphambanisa: Thuthukisa ukugcinwa kwamanzi, vikela ukuqhekeka kodaka, futhi uthuthukise ukunamathela.

I-Tile Adhesive: Thuthukisa ukunamathela, yenza ngcono ukusungulwa lula, futhi uvikele amathayili ekusheleleni.

Udaka lokuzimela: thuthukisa uketshezi, vimbela ukuhlukaniswa, futhi uthuthukise amandla.

UDotar ongangeni manzi: Thuthukisa ukusebenza kwamanzi futhi wandise ubuningi bodaka.

I-PuTTY Powder: Thuthukisa ukusebenza kokwakha, thuthukisa ukumelana nokukhuphuka, futhi uvikele i-poffaing.

4. Ukukhetha kwe-HPMC nokusebenzisa izinyathelo zokuphepha

Imikhiqizo ehlukene yodaka inezidingo ezihlukile ze-HPMC, ngakho-ke izinto ezilandelayo zidinga ukubhekwa lapho zikhetha:

I-Viscosity: I-Low-VisChel®HPMC ilungele udaka oluzenzakalelayo olunobunzima obuhle, kanti i-high-vissusity hpmc ilungele ukunamathela kwama-putty noma uthayela ngamanzi aphezuluizidingo zokugcina.

I-Solubinity: I-HPMC esezingeni eliphakeme kufanele ibe ne-soubelity enhle, ikwazi ukuhlakaza ngokushesha futhi yakha isixazululo esifanayo ngaphandle kwe-agglomeration noma i-agglomeration.
Inani lezengezo: Ngokujwayelekile, inani lokungezwa le-HPMC ku-wortar oxutshwe ngo-0,1% ~ 0.5%, kanye nengxenye ethile yezilinganiso ezidinga ukulungiswa ngokuya ngezidingo zokusebenza kodaka.

I-HPMCIngabe isengezo esibalulekile ku-wonduke oxutshwe omile, ongathuthukisa ukusebenza kokwakha, ukugcinwa kwamanzi nokutholwa kodaka. Kusetshenziswa kabanzi ku-masonry udaka, udaka olunamathela ngokunamathela, ama-putty neminye imikhiqizo. Lapho ukhetha i-HPMC, kuyadingeka ukufanisa i-viscosity efanelekile nefomula ngokuya ngesimo esithile sohlelo lokusebenza ukuqinisekisa umphumela omuhle kakhulu wokwakha.
