Ungayikhetha kanjani i-Hydroxypropyll methylcellulose ngodaka kadaka?

Inani elijwayelekile le-PH yemikhiqizo ye-Gypsum i-acid noma engathathi hlangothi. Manje kunezinhlobo ezimbili zebanga lokwakhahydroxypropyl methylcelluloseEmakethe: Slow-Slow-Slow-Cellulose kanye nama-cellulose (ama-cellulose asheshayo. I-cellulose esheshayo ayilungele izinhlelo ze-gypsum. Imikhiqizo, i-solubity impofu kakhulu ngaphansi kwezimo ze-acidic noma ezingathathi hlangothi, futhi i-hydroxypropylylylylylylylylylylylylylylyk ingahlukaniswa kancane imikhiqizo ye-gypsum, kepha i-cellulose yejubane inenkinga enkulu, kulula ukuncibilikisa (lapho i-gypsum ngemuva kokuthi udaka oluvuthiwe Udonga okwesikhashana, izindawo ezincane ze-granular zivame ukuvela ebusweni). Njengamanje, emikhiqizweni ye-gypsum, ikakhulukazi ngodaka olufafazwe ngomshini ofafazwe ngo-gypsum, kuyadingeka ukuthi i-cellulose ether ingahlakazeka ngokugcwele futhi ichithwe ngesikhathi esifushane kakhulu, esidinga ukuthi sisebenzele ngokuningiliziwe ngokuncibilikisa i-ether inqubo yokukhiqiza. Ukwelashwa okungaphezulu (hhayi ukubizwa okubizwa ngokuthi ukungezelelwa kwezinye izengezo ku-Ether ye-Cellulose ejwayelekile), ukuze uzivumelanise nezimo ezinhlelweni zodaka lwe-gypsum. I-Hydroxypropyllylyl ether enokwelashwa okujulile ingaba nesikhathi esizinzile sokuqothula kanye nezindawo ezinhle zomeyili ku-gypsum ngodaka, futhi kungathuthukisa kakhulu inqubo yokulinganisa nokuqeda udaka.

Udaka olufashisayo lomshini olufafazwe ngokuvamile lusebenzisa i-hydroxcellosity hydroxcellosel methylcellose ether phakathi kuka-20,000 no-75,000, futhi inani lokungezwa ngokuvamile lingu-0.4%. Isikhathi sokubekwa kwe-gypsum efafazwe ngomshini silawulwa cishe ngehora eli-1. Sisebenzisa ukucindezelwa kwesivuno sikaGypsum Gotar, i-viscosity yepulasitiki, i-Thixotropy, i-Rheology kanye nokuvumelana okuguquguqukayo kwe-slurry ukwahlulela ukusebenza kwemikhiqizo yodumbu ye-gypsum.

Sicabanga ngokulawulwa kwekhwalithi ye-Deselfurization Gypsururization Calcinging inqubo, ama-filler (usimende, i-aggregate enhle, i-handdluum powder) kanye ne-admixtures (ingasetshenziswa ekusakazeni i-latex celtulose ether, i-perlite perlite, i-gypsum retardrer) Ukukhetha okuphelele Ifomula yomkhiqizo ibiza kakhulu.

I-Hydroxypropyll methyl cellulose etherKu-gypsum udaka unobumsulwa obukhulu nokusebenza okuhle, futhi kunconywe kabanzi ngamakhasimende kaGypsum Datar.
