Zowonjezera Konkire Zopepuka | Zida Zapamwamba Zotulutsa thovu pa Ma Cellular Concrete
The kuchepetsa madzi zimapanga madzi abwino kuchepetsa zotsatira mu ntchito konkire ndipo zimakhudza mwachindunji pa konkire performance.The pamwamba pa madzi kuchepetsa wothandizila ali wabwino yogwira mankhwala. Pansi pa mankhwala zochita za yogwira zakuthupi, particles simenti mu konkire ndi adsorbed ndi madzi kuchepetsa wothandizira, ndi particles simenti kupanga mtundu womwewo wa magetsi charge.The particles simenti analekanitsidwa pansi zochita za madzi kuchepetsa wothandizira yogwira zinthu., kuchepetsa kuthamanga kwa pamwamba pa simenti ndi madzi, ndi kuonjezera kukhudzana area.The madzi zili mu particles simenti ndi mokwanira anachita, ndipo zotsatira za kuchepetsa kuchuluka kwa simenti kapena madzi pamapeto pake zimatheka pansi pa chikhalidwe chokhala ndi mphamvu.
Kumvetsetsa bwino mawonekedwe a chochepetsera madzi othamanga kwambiri ndikuchigwiritsa ntchito moyenera sikungothandiza kukonza bwino ntchito yomanga, komanso kupititsa patsogolo phindu lazachuma ndikupangitsa kuti zikhale bwino pantchito zomanga zauinjiniya.
1.Wamba madzi ochepetsa ndi superplasticizer ayenera kuyesedwa pH mtengo, kachulukidwe (kapena ubwino) ndi kuchepetsa madzi musanagwiritse ntchito, ndipo angagwiritsidwe ntchito pokhapokha atakwaniritsa zofunikira.Kutsimikiza kwa mlingo woyenera kwambiri kuyenera kukwaniritsa zofunikira zogwirira ntchito monga mphamvu ya mapangidwe., kutha ntchito, kulimba ndi chuma cha zomangamanga chilengedwe chilengedwe.Malinga ndi mlingo analimbikitsa woperekedwa ndi katundu, Mlingo wololera umapezeka kudzera mu kuyesa kofananira.Kuchulukirachulukira kwa wochepetsera madzi ochita bwino kwambiri kumapangitsa kuyipitsa konkriti ya simenti komanso kutayika kwakukulu kwa matope a simenti., kumabweretsa kusakwanira kokwanira komanso kukhudza mphamvu.
2. Mankhwala ochepetsera madzi ayenera kupangidwa kukhala njira yofananira.Zowonongeka za mpweya wa admixture ndizofanana ndi za admixtures.Solid precipitates zomwe sizikusungunuka muzitsulo ziyenera kuchotsedwa tsiku ndi tsiku.Malinga ndi zosowa za polojekitiyi., wamba kuchepetsa wothandizila madzi ndi superplasticizer akhoza pamodzi ndi zina miscible admixtures.
3. Kuwonjezera mchere, chochepetsa kutentha kwambiri, pulasitiki kapena chochepetsera madzi chamtundu wocheperako chomwe chili choyenera kupangira simenti muzitsulo zochepetsera madzi bwino kwambiri zitha kuchepetsa kugwa kwanyengo yotentha.,Ponyamula konkire ya simenti ndi chosakanizira kapena tanker, superplasticizer ikhoza kuwonjezeredwa kawiri pa malo otsanulira.Pambuyo pa kusakaniza mofulumira komanso ngakhale kutulutsa, palibenso madzi omwe amawonjezeredwa, ndi kuthira, kunjenjemera, kuyang'ana, ndi zina. zimatsirizidwa mwamsanga; njira yochepetsera madzi yochepetsera kwambiri imagwiritsidwa ntchito.
4.Ulalo waumoyo ndiye ulalo wofunikira woonetsetsa kuti kapangidwe ka konkire ka simenti sikutulutsa ming'alu ndi ming'alu yaying'ono., Highway engineering simenti kapangidwe ka madzi wamba kuchepetsa wothandizila madzi ndi mkulu-mwachangu kuchepetsa madzi ayenera kulimbikitsidwa ndi inshuwaransi posachedwapa.Mamembala konkire simenti ndi wothandizila madzi kuchepetsa madzi si oyenera nthunzi.;The simenti konkire chigawo chimodzi ndi retarding mtundu kuchepetsa wothandizila madzi ayenera kuonetsetsa kuti simenti konkire ndipamene mphamvu structural zina pambuyo nthawi ya malo amodzi amasiya kukhala steamed.Simenti konkire wothira superplasticizer akhoza kuchiritsidwa ndi steaming..
Cie-China.org ndiye wotsogola wotsogola wa konkriti wa thovu yemwe amapereka thovu la konkriti, superplasticizer,thovu konkire mphamvu zowonjezera kwa wopepuka konkire, Zolemba za CLC. Ngati mukuyang'ana superplasticizer, chonde khalani omasuka Lumikizanani nafe.
