Iyini i-HPMC yodaka oluxutshwe okomile?

1. Incazelo ye-HPMC
I-HPMC (Hydroxypropyl Methyl Cellulose)iyi-ether engeyona ionic cellulose esetshenziswa kabanzi ezintweni zokwakha, imithi, ukudla, amakhemikhali nsuku zonke nezinye izimboni. Kudaka oluxutshwe okomile, i-AnxinCel®HPMC isetshenziswa ngokuyinhloko njenge-thickener, i-ejenti egcina amanzi kanye nesilungisi, engathuthukisa kakhulu ukusebenza kokwakhiwa kodaka.

2. Iqhaza le-HPMC kudaka oluxutshwe okomile

Imisebenzi esemqoka ye-HPMC odakeni oluxutshwe okomile imi kanje:

Ukugcinwa kwamanzi: I-HPMC ingakwazi ukumunca amanzi futhi ikhukhumale, yenze ifilimu ye-hydration ngaphakathi kodaka, inciphise ukuhwamuka kwamanzi ngokushesha, ithuthukise ukusebenza kahle kwe-hydration kasimende noma i-gypsum, futhi ivimbele ukuqhekeka noma ukulahlekelwa amandla okubangelwa ukulahlekelwa kwamanzi amaningi.

Ukujiya: I-HPMC inikeza udaka i-thixotropy enhle, okwenza udaka lube nezakhiwo ezifanele zokuguquguquka nokwakhiwa, nokugwema ukugeleza kwamanzi kanye nokucwiliswa kwenhlabathi okubangelwa ukuhlukana kwamanzi.

Thuthukisa ukusebenza komsebenzi wokwakha: I-HPMC ithuthukisa ukuthambisa kodaka, ikwenze kube lula ukuyisebenzisa kanye neleveli, kuyilapho ithuthukisa ukunamathela ku-substrate futhi yehlisa ukuba yimpushana nokubhoboza.

Nweba isikhathi esivulekile: I-AnxinCel®HPMC inganciphisa izinga lokuhwamuka kwamanzi, inwebise isikhathi sokusebenza sodaka, yenze ukwakhiwa kuhambisane nezimo, futhi ifaneleka ngokukhethekile ukusetshenziswa kwendawo enkulu kanye nezindawo zokwakha ezisezingeni eliphezulu.

I-Anti-sagging: Kuzinto zokwakha eziqondile ezifana nezinamathelisi zamathayili nama-putty, i-HPMC ingavimbela okokusebenza ekusheleleni phansi ngenxa yesisindo sayo futhi kuthuthukise ukuqina kokwakhiwa.

3. Ukusetshenziswa kwe-HPMC kumasimende ahlukene axutshwe okomile

I-HPMC isetshenziswa kabanzi ezinhlotsheni ezahlukahlukene zodaka oluxutshwe okomile, okuhlanganisa kodwa kungagcini nje:

Udaka lwamatshe kanye nodaka lokuplasta: thuthukisa ukugcinwa kwamanzi, uvimbele ukuqhekeka kodaka, futhi uthuthukise ukunamathela.

Ukunamathiswa kwethayela: thuthukisa ukunamathela, thuthukisa ukwakhiwa kalula, futhi uvimbele amathayela ukuthi angasheleli.

Udaka oluzilinganisa ngokwalo: thuthukisa uketshezi, vimbela ukuhlukaniswa, futhi uthuthukise amandla.

Udaka olungenamanzi: thuthukisa ukusebenza okungangeni manzi futhi ukhuphule ukuminyana kodaka.

I-Putty powder: thuthukisa ukusebenza kokwakhiwa, uthuthukise ukumelana nokukhuhla, futhi uvimbele ukuba yimpushana.

4. Ukukhethwa kwe-HPMC nokusebenzisa izinyathelo zokuphepha

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

I-Viscosity: I-Low-viscosity i-AnxinCel®HPMC ilungele udaka oluzilinganisa lona olunoketshezi oluhle, kuyilapho i-HPMC ene-viscosity ephezulu ifanele i-putty noma i-adhesive adhesive ngamanzi aphezulu.izidingo zokugcina.

Ukunyibilika: Ikhwalithi ephezulu ye-HPMC kufanele ibe nokuncibilika okuhle, ikwazi ukuhlakazeka ngokushesha futhi yakhe isixazululo esifanayo ngaphandle kokuhlanganisa noma ukuhlanganisa.
Inani elingeziwe: Ngokuvamile, inani elingeziwe le-HPMC odakeni oluxutshwe okomile lingu-0.1%~0.5%, futhi ingxenye ethile idinga ukulungiswa ngokuya ngezidingo zokusebenza kodaka.

I-HPMCiyisengezo esibalulekile odakeni oluxutshwe okomile, olungathuthukisa ukusebenza kokwakhiwa, ukugcinwa kwamanzi kanye nokunamathela kodaka. Isetshenziswa kabanzi ekwenzeni udaka lwamatshe, udaka lokunamathisela, i-adhesive tile, putty neminye imikhiqizo. Lapho ukhetha i-HPMC, kuyadingeka ukufanisa i-viscosity efanele kanye nefomula ngokuya ngesimo sohlelo oluthile ukuze kuqinisekiswe umphumela wokwakha ongcono kakhulu.
