dziwitsani:
Konkire ndi chinthu chofunikira chomangira chomwe chimadziwika chifukwa champhamvu komanso kulimba kwake. Kuwonjezeredwa kwa superplasticizers kunasintha ukadaulo wa konkriti powongolera magwiridwe antchito komanso kuchepetsa chinyezi. Njira yochepetsera madzi yochokera ku Gypsum ndi njira yabwino kwambiri yochepetsera madzi yomwe yakopa chidwi kwambiri.
Chidziwitso choyambirira cha konkriti superplasticizer:
Superplasticizers ndi zowonjezera zomwe zimagwiritsidwa ntchito mu konkire kuti ziwonjezere kuyenda popanda kuwononga mphamvu. Ndiwofunikira pamapulogalamu omwe amafunikira kuti azigwira ntchito kwambiri, monga konkriti yogwira ntchito kwambiri, konkriti yodzipangira yokha komanso zinthu zotsogola.
Gypsum ngati wothandizira kwambiri kuchepetsa madzi:
Gypsum ndi mchere wachilengedwe womwe umagwiritsidwa ntchito pomanga. M'zaka zaposachedwa, ochita kafukufuku adafufuza momwe angagwiritsire ntchito bwino kwambiri kuchepetsa madzi chifukwa cha mankhwala ake apadera.
Chemical kapangidwe ndi limagwirira ntchito:
Ndikofunikira kumvetsetsa kapangidwe kake ka gypsum-based superplasticizers. Gypsum kapena calcium sulphate dihydrate imalumikizana ndi tinthu tating'ono ta simenti, potero kumathandizira kubalalitsidwa ndikuchepetsa kuchuluka kwa simenti yamadzi.
Ubwino wa gypsum-based superplasticizer:
A. Kugwira ntchito bwino: Gypsum-based superplasticizer imapangitsa kuti konkriti igwire ntchito bwino, kuti ikhale yosavuta kuyiyika ndi kumaliza.
b. Kukula kwamphamvu: Mosiyana ndi zovuta zina, zowonjezera za gypsum sizimasokoneza mphamvu ya konkire. M'malo mwake, zingathandize kukulitsa kukula kwamphamvu koyambirira.
C. Kuchepetsa zofunikira za madzi: Ma superplasticizers opangidwa ndi Gypsum amatulutsa konkire yotsika kwambiri yokhala ndi madzi ocheperako, potero amawonjezera kulimba komanso kuchepetsa kutulutsa.
Tekinoloje yokhazikika ya konkriti:
Kufunafuna zida zomangira zokhazikika kwapangitsa kufunafuna zowonjezera zachilengedwe. Gypsum ndi yochuluka komanso yopezeka kwambiri, zomwe zimathandizira kukhazikika kwa kupanga konkriti.
A. Kuchepetsa mpweya wa carbon: Ma superplasticizers opangidwa ndi Gypsum atha kuthandiza kuchepetsa kuchuluka kwa mpweya wa konkriti poyerekeza ndi zowonjezera zachikhalidwe.
b. Kugwiritsa ntchito zinyalala: Kugwiritsa ntchito gypsum, zomwe zimagwiritsidwa ntchito m'mafakitale osiyanasiyana, monga njira yochepetsera madzi yochepetsera madzi ikugwirizana ndi mfundo za chuma chozungulira komanso kuchepetsa zinyalala.
Mavuto ndi malingaliro:
Ngakhale kuti ma superplasticizer opangidwa ndi gypsum ali ndi chiyembekezo, zovuta zina ziyenera kuthetsedwa. Izi zikuphatikizapo kuchedwa komwe kungachitike pakukhazikitsa nthawi, kusintha kwa katundu kutengera mtundu wa simenti, ndi zotsatira za nthawi yayitali pa kulimba.
Mapulogalamu ndi ziyembekezo zamtsogolo:
Gypsum-based superplasticizers amatha kugwiritsidwa ntchito mumitundu yosiyanasiyana ya konkriti, kuphatikiza konkriti yodzipangira yokha, konkriti yogwira ntchito kwambiri, komanso ngakhale pamapulogalamu omwe kukhazikika ndikofunikira.
A. Ntchito Zomangamanga: Kugwiritsa ntchito ma superplasticizer opangidwa ndi gypsum m'mapulojekiti akuluakulu a zomangamanga kumatha kupititsa patsogolo bwino ntchito, kulimba komanso kuwononga chilengedwe.
b. Kafukufuku ndi Chitukuko: Kafukufuku wopitilira amayang'ana kwambiri kuwongolera kapangidwe ka ma superplasticizers opangidwa ndi gypsum, kuthana ndi zovuta, ndikuwunika kulumikizana ndi zowonjezera zina kuti mugwire bwino ntchito.
Pomaliza:
Mwachidule, ma superplasticizers opangidwa ndi gypsum ndi njira yodalirika yopititsira patsogolo magwiridwe antchito komanso kukhazikika. Pamene ntchito yomanga ikupitabe patsogolo, kufufuza kwa zipangizo zamakono ndi zowonjezera zimakhala zofunikira kuti zikwaniritse zosowa zamtsogolo. Ndi mawonekedwe ake apadera komanso zabwino zomwe zingakhalepo, ma gypsum-based superplasticizer amathandizira kupititsa patsogolo ukadaulo wa konkriti m'njira yabwino komanso yosamalira chilengedwe.
