Chii chinonzi gypsum-based self-leveling mortar?
Gypsum-based self-leveling imhando nyowani yepasi inomisa zvinhu zvakasvibira, zvakatipoteredza uye zvemhando yepamusoro. Nekushandisa kuyerera kwakanaka kwegypsum-based self-leveling mortar, nzvimbo yakakura yevhu rakatsetseka inogona kuumbwa munguva pfupi. Iine zvakanakira kupfava kwepamusoro, kunyaradza kwakanaka, kuvharisa hunyoro, kusamira kwezvipembenene, kudzivirira zvipembenene, nezvimwewo, uye iri nyore kuvaka uye inokurumidza kurarama. Yakakodzera kuenzana uriri mukati memba, sekuyera makushion ekuisa makapeti, uriri, uye mataira euriri mumahotera, makamuri emahofisi ekutengeserana, uye kushongedzwa kwemba.
Zvinhu zvikuru zvegypsum-based self-leveling mortar ndezvizvi:
1.Cementitious zvinhu: Iyo cementitious material yegypsum-based self-leveling mortar ndeyepamusoro-mhando yekuvaka gypsum. Zvigadzirwa zvekugadzira gypsum yekuvaka zvinonyanya kugadzirwa gypsum ine calcium sulfate kana maindasitiri ne-chigadzirwa gypsum mushure mekutanga uye kucheneswa, uye yekuvaka gypsum poda inosangana neyakajairwa yenyika inowanikwa necalcining pane inonzwisisika process tembiricha.
2.Active admixtures: Fly ash, slag poda, nezvimwewo zvinogona kushandiswa seanoshingaira admixtures e-self-leveling zvinhu. Chinangwa ndechekuvandudza kukwidziridzwa kwezvinhu uye kugadzirisa mashandiro eiyo yakaoma zvinhu. Iyo inoshanda musanganiswa uye simentitious zvinhu zvinogona kuvandudza compactness uye gare gare kusimba kwechimiro chechinhu kuburikidza neiyo hydration reaction.
3. Retarder: Nguva yekumisikidza indekisi yakakosha yekuita indekisi yezvinhu zvekuzvimiririra. Nguva pfupi kana yakarebesa haikodzeri kuvaka. Iyo inodzoreredza inomutsa chiitiko chegypsum, inogadzirisa iyo supersaturated crystallization kumhanya ye dihydrate gypsum, uye inochengeta kuseta uye kuomesa nguva yezvinhu zvekuzvimisa-leveling mune inonzwisisika renji.
4. Mvura inoderedza mumiririri: Kuti uvandudze kusungirirwa uye kusimba kwezvinhu zvekuzvimisa, zvakakosha kuderedza mvura-binder ratio. Pasi pemamiriro ekuchengetedza zvakanaka fluidity yezvinhu zvekuzvimisa-leveling, zvinodikanwa kuwedzera mvura inoderedza vamiririri. Mvura inodzikisira inoenderana neakasiyana ekuvaka gypsum anogona kushandiswa kuita kutsvedza pakati pezvinhu zvimedu zviri nyore, nekudaro kuderedza huwandu hwemvura inosanganiswa inodiwa uye kugadzirisa chimiro chechinhu chakaomeswa.
5. Mvura inochengetedza mumiriri: Zvigadzirwa zvekuzvimiririra zvinovakwa pahwaro hwepasi, uye ukobvu hwekuvaka hutete, uye mvura inotorwa nyore nyore nepasi, zvichikonzera kusakwana kwemvura yezvinhu, kuputika pamusoro, uye. kuderedzwa simba. Kazhinji, low-viscosity (isingasviki 1000) cellulose ether (HPMC) inoshandiswa sechinhu chinochengetedza mvura. Cellulose ether ine yakanaka wettability, kuchengetedza mvura uye firimu-kuumba zvinhu, kuitira kuti iyo yega-leveling zvinhu irege kubuda ropa uye yakazara hydrated.
6. Defoaming agent: The defoaming agent inogona kuvandudza kushanda kwakajeka kwezvinhu zvekuzvigadzirisa, kuderedza mabhubhu emhepo kana zvinhu zvichiumbwa, uye kuva nemigumisiro yekuvandudza simba rezvinyorwa.
