matope odziyimira pawokha okhala ndi gypsum ndi zida zazikulu

Kodi matope odziyimira pawokha opangidwa ndi gypsum ndi chiyani?
Gypsum-based self-leveling ndi mtundu watsopano wa zinthu zomwe zimakhala zobiriwira, zachilengedwe komanso zamakono. Pogwiritsa ntchito kusuntha kwabwino kwa matope odziyimira pawokha opangidwa ndi gypsum, malo akulu okhala bwino amatha kupangidwa kwakanthawi kochepa. Zili ndi ubwino wa flat flatness, chitonthozo chabwino, kuteteza chinyezi, mildew resistance, tizilombo toyambitsa matenda, ndi zina zotero, ndipo ndizosavuta kumanga komanso kupulumuka mwamsanga. Ndi yoyenera kusanja pansi m'nyumba, monga kusalaza ma cushion oyika makapeti, pansi, ndi matailosi apansi m'mahotela, zipinda zamaofesi amalonda, ndi zokongoletsera kunyumba.

Zida zazikulu zopangira matope a gypsum self-leveling ndi motere:

1. Cementitious material: Simenti yopangidwa ndi gypsum self-leveling mortar ndi apamwamba kwambiri kumanga gypsum. Zopangira zopangira gypsum yomanga makamaka gypsum yachilengedwe yokhala ndi calcium sulfate kapena gypsum yopangidwa ndi mafakitale pambuyo pokonzekera ndi kuyeretsedwa, ndipo ufa wa gypsum womanga womwe umakwaniritsa mulingo wadziko umapezeka mwa calcining pa kutentha koyenera.

2.Active admixtures: Fly phulusa, slag ufa, etc. angagwiritsidwe ntchito ngati admixtures yogwira kwa zipangizo kudzidalira. Cholinga ndi kusintha tinthu gradation wa zinthu ndi kusintha ntchito ya oumitsa zakuthupi. The yogwira admixture ndi cementitious zakuthupi akhoza kusintha compactness ndipo kenako mphamvu ya zinthu dongosolo mwa hydration anachita.

3. Retarder: Nthawi yoikika ndi chilolezo chofunikira cha zida zodzipangira zokha. Nthawi yayifupi kapena yayitali siyenera kumanga. The retarder kumapangitsa ntchito ya gypsum, kusintha supersaturated crystallization liwiro la dihydrate gypsum, ndipo amasunga zoikamo ndi kuumitsa nthawi ya zipangizo kudzikonda leveling mu osiyanasiyana wololera.

4. Mankhwala ochepetsera madzi: Pofuna kupititsa patsogolo kugwirizanitsa ndi mphamvu za zipangizo zodzipangira okha, m'pofunika kuchepetsa chiwerengero cha madzi-binder. Pansi pa chikhalidwe chokhala ndi madzi abwino a zipangizo zodzipangira okha, m'pofunika kuwonjezera zochepetsera madzi. Zochepetsera madzi zomwe zimagwirizana ndi ma gypsums omangira osiyanasiyana zitha kugwiritsidwa ntchito kuti kutsetsereka pakati pa tinthu tating'ono ting'onoting'ono kukhale kosavuta, potero kuchepetsa kuchuluka kwa madzi osakaniza ofunikira ndikuwongolera kapangidwe kazinthu zolimba.

5. Madzi osungira madzi: Zida zodzipangira zokha zimapangidwira pansi, ndipo makulidwe a zomangamanga ndi ochepa kwambiri, ndipo madzi amatengedwa mosavuta ndi pansi, zomwe zimapangitsa kuti zinthuzo zikhale zosakwanira, ming'alu pamtunda, ndi mphamvu zochepa. Nthawi zambiri, low-viscosity (zosakwana 1000) cellulose ether (HPMC) imagwiritsidwa ntchito ngati chosungira madzi. Ether ya cellulose imakhala ndi chinyezi chabwino, kusunga madzi komanso kupanga mafilimu, kotero kuti zinthu zodzikongoletsera sizimatuluka magazi ndipo zimakhala ndi madzi okwanira.
6. Defoaming agent: The defoaming agent amatha kusintha maonekedwe a zinthu zodzikongoletsera, kuchepetsa mpweya wa mpweya pamene zinthuzo zimapangidwira, ndipo zimakhala ndi zotsatira zina zowonjezera mphamvu za zinthuzo.
