Ukusetshenziswa kwe-HPMC embonini yezokwakha

I-Hydroxypropyl methyl cellulose, ebizwa ngokuthi i-cellulose (HPMC), yenziwe nge-cotton cellulose emsulwa kakhulu njengento eluhlaza futhi ifakwa etherified ngokukhethekile ngaphansi kwezimo ze-alkali. Yonke le nqubo iqedwa ngaphansi kokuqapha okuzenzakalelayo futhi ayinazo izithako Ezisebenzayo njengezitho zezilwane namafutha.

I-Cellulose HPMC inokusetshenziswa okuningi, njengokudla, imithi, ikhemistri, izimonyo, imboni yeziko, njll. Okulandelayo kwethula kafushane ukusetshenziswa kwayo embonini yezokwakha:

1. Udaka lukasimende: thuthukisa ukuhlakazwa kwesihlabathi sikasimende, uthuthukise kakhulu ipulasitiki nokugcinwa kwamanzi kodaka, ube nomthelela ekuvimbeleni ukuqhekeka, futhi uthuthukise amandla kasimende;

2. Usimende wethayela: thuthukisa ipulasitiki kanye nokugcinwa kwamanzi kodaka lwethayela elicindezelwe, thuthukisa ukunamathela kwamathayili, futhi uvimbele ukugobhoza;

3. Ukumbozwa kwezinto eziphikisayo njenge-asbestos: njenge-ejenti elengayo, i-ejenti ethuthukisa uketshezi, futhi kuthuthukisa amandla okubopha ku-substrate;

4. I-Gypsum coagulation slurry: thuthukisa ukugcinwa kwamanzi nokucutshungulwa, futhi uthuthukise ukunamathela ku-substrate;

5. Usimende ohlanganyelwe: wengezwe kusimende ohlangene we-gypsum board ukuze kuthuthukiswe uketshezi kanye nokugcinwa kwamanzi;

6. I-Latex putty: thuthukisa i-fluidity nokugcinwa kwamanzi kwe-putty ngokusekelwe ku-resin latex;

7. I-Stucco: Njenge-paste ethatha indawo yemikhiqizo yemvelo, ingathuthukisa ukugcinwa kwamanzi futhi ithuthukise amandla okubopha nge-substrate;

8. Izembatho: Njenge-plasticizer yezingubo ze-latex, ingathuthukisa ukusebenza kokusebenza kanye ne-fluidity ye-coatings nama-putty powders;

9. Ukufafaza upende: Kunomphumela omuhle ekuvimbeleni ukucwila kukasimende noma izinto zokufafaza ze-latex nama-filler nokuthuthukisa uketshezi kanye nephethini yesifutho;

10. Imikhiqizo yesibili kasimende ne-gypsum: isetshenziswa njenge-extrusion molding binder ye-hydraulic substances njenge-cement-asbestos, ukuthuthukisa uketshezi kanye nokuthola imikhiqizo ehlanganisiwe efanayo;

11. I-Fiber wall: Ngenxa ye-anti-enzyme kanye nomphumela wokulwa namagciwane, iyasebenza njengesibopho sezindonga zesihlabathi;

12. Abanye: Ingasetshenziswa njenge-ejenti egcina ibhamuza lomoya (inguqulo ye-PC) odakeni oluncane lwesihlabathi sobumba kanye no-opharetha we-plaster.
