Kugwiritsa ntchito Hydroxypropyl Methyl Cellulose mu Gypsum Mortar

(1), makhalidwe ahydroxypropyl methylcellulose mu matope a gypsum:

1. Ntchito yomanga bwino: ndi yosavuta komanso yosalala kupachika, ikhoza kupangidwa nthawi imodzi, ndipo imakhala ndi pulasitiki nthawi imodzi.

2. Kugwirizana kwamphamvu: Ndikoyenera kwa mitundu yonse ya maziko a gypsum, ndipo amatha kuchepetsa nthawi yomira ya gypsum, kuchepetsa kuyanika kwa shrinkage, ndipo khoma silophweka kubisala ndi kusweka.

3. Kuchuluka kwa madzi osungira madzi abwino: kumatha kutalikitsa nthawi yogwiritsira ntchito gypsum base, kupititsa patsogolo kukana kwa gypsum base, kuonjezera mphamvu zomangira pakati pa gypsum base ndi maziko, ntchito yabwino yonyowa, ndi kuchepetsa phulusa lofika ndi mavuto ena.

4. Kupititsa patsogolo kufalikira kwa maziko a gypsum: Poyerekeza ndi hydroxypropyl methylcellulose ether yofanana, kufalikira kudzawonjezeka kwambiri. Mankhwala a Hydroxypropyl methylcellulose amatha kukulitsa kuchuluka kwa ❖ kuyanika, amatha kuphimba madera ambiri, amachepetsa kulimbikira kwa ntchito, kupulumutsa zida, ndikuwongolera phindu pazachuma.

5. Kuchita bwino kwa anti-sagging: popachika zigawo zokhuthala, kumanga kwachiphaso chimodzi sikudzagwedezeka, ndipo maulendo oposa awiri, pamwamba pa 3cm, sangagwedezeke pamene akulendewera, ndipo pulasitiki ndi yabwino.

6. Magawo ogwiritsira ntchito ndi mlingo: gypsum yopepuka pansi yopepuka, mlingo woyenera ndi 2.5-3.5 kg/tani.

(2) Kuyesa kuyesa kwa hydroxypropyl methylcellulose:

1. Kuyesa kwamphamvu: Pambuyo poyesedwa, gypsum-based hydroxypropyl methylcellulose imakhala ndi mphamvu yabwino yomangirira komanso kukakamiza.

2. Kuyesa kwa anti-sagging: Palibe kugwedezeka pamene kumanga chiphaso chimodzi kumagwiritsidwa ntchito mumagulu akuluakulu, ndipo palibe sag pamene ikugwiritsidwa ntchito kwa maulendo oposa awiri (pamwamba pa 3cm), ndipo pulasitiki ndi yabwino.

3. Mayeso opachika khoma: ndi opepuka komanso osalala akamapachika, ndipo amatha kupangidwa nthawi imodzi. Pamwambapo ndi wofewa komanso wonyezimira.

4. Mayeso a kufalikira kwa gypsum base: Kufalikira kwa gypsum base kumatanthawuza zotsatira zomwe zapezedwa poyesa kuchuluka kwa madzi kwa gypsum base. Toni imodzi yazinthu zopangidwa ndi gypsum zomangira khoma la 10mm wandiweyani.

5. Kuyesa kwamadzi osungira madzi: Kusungirako madzi muyeso wa GB/T28627-2012 "Plastering Gypsum", kuchuluka kwa madzi osungira pansi pa gypsum yopepuka ndi yayikulu kuposa kapena yofanana ndi 60%, ndi 0.2% ndi 0.25% ya gypsum-based hydroxypropyl methylcellulose iwonjezedwa Ili ndi ntchito yabwino yosungira madzi.
