Mlingo wochepa, womwe umagwira ntchito yofunika kwambiri pakusintha konkire.Ndi chitukuko chapang'onopang'ono chamakampani omanga, kufunikira kwa konkriti mumapulojekiti a uinjiniya kukukulirakulira, ndipo panthawi imodzimodziyo, pali zofunika kwambiri pakugwira ntchito ndi mtundu wa konkriti.M'nkhaniyi, monga chinthu chofunikira chaumisiri chomwe chingathe kupititsa patsogolo ntchito ya konkire, zosakaniza za konkire zakhala zofunikira kwambiri pachisanu mu konkire yamakono kupatula simenti, mchenga, miyala ndi madzi.
Wothandizira kwambiri wochepetsera madzi Wochepetsera madzi amagawidwa makamaka m'magulu atatu: wamba wochepetsera madzi, wochepetsetsa kwambiri wamadzimadzi komanso wochepetsera madzi.Kukula kwa superplasticizers kwadutsa magawo atatu: m'badwo woyamba wa superplasticizer wamba woimiridwa ndimatabwa a calcium, m'badwo wachiwiri wa superplasticizers woimiridwa ndinaphthalenemndandanda, ndi m'badwo wachitatu wa superplasticizers woimiridwa ndipolycarboxylate superplasticizermndandanda.Mbadwo wapamwamba-performance superplasticizer siteji.Polycarboxylate superplasticizerali ndi ubwino wa mlingo wochepa komanso kuchepetsa madzi, ndipo angagwiritsidwe ntchito popanga mphamvu zamphamvu, zowonjezereka, zowonjezereka komanso zowonjezereka;Njirayi ilibe zinyalala zamadzimadzi, gasi wotayirira, zotsalira za zinyalala ndi zinthu zina.Ndiwobiriwira komanso wokonda zachilengedwe wochepetsera madzi, ndipo ali ndi zabwino zoonekeratu pakuteteza chilengedwe komanso kuchita bwino.Ndikukula kwa mphamvu zopanga komanso kuwongolera kwamphamvu, ma polycarboxylate superplasticizers akhala mitundu yayikulu ya superplasticizer yomwe imapangidwa ndikudyedwa mdziko langa.
Pankhani ya "kukula kosasunthika" komwe kukuyembekezeka kupitiliza kutenthedwa, kuwonjezeka kwa kufunikira kwa konkriti komwe kumabwera chifukwa cha kuwonjezeka kwa mapulani a ntchito zazikulu zaumisiri komanso kupita patsogolo kwa dongosolo la zomangamanga kudzakulitsa kufunikira kwa zosakaniza za konkire pa. nthawi yomweyo.Kuphatikiza apo, malinga ndi malipoti a ntchito za boma omwe aperekedwa ndi zigawo zosiyanasiyana, ntchito yomanga zomangamanga monga zoyendera ndi kusungirako madzi ndi gawo lalikulu la ntchito zazikulu, ndipo ma projekiti omwe tawatchulawa ali ndi zofunika kwambiri pakuchita konkriti, komanso madzi ochita bwino kwambiri. ochepetsa amafunika kukwaniritsa zofunikira za konkriti.Poyerekeza ndi mitundu ina ya admixtures, zomangira kupopera zosowa ndi kuchepetsa kugwedera ngakhale kugwedera-free zosowa za ntchito yapadera konkire ali ndi ubwino zoonekeratu.Chifukwa chake, kuchuluka kwa kufunikira kwa othandizira ochepetsa madzi omwe amagwira ntchito kwambiri omwe amatha kukwaniritsa ntchito zauinjiniya "zopangidwa mwaluso" akuyembekezeka kuchulukirachulukira.
Bizinesi yamakampani ya Jufu Chemical Company kusiyapo bizinesi yayikulu yopangira zida zapamwamba imawonetsa malingaliro azinthu zomwe ndi zosiyana kwambiri ndi omwe akupikisana nawo.M'tsogolomu, idzatha kubwereza kupambana kwa bizinesi ya superplasticizer, ndipo denga la msika ndilokwera kwambiri kuposa la superplasticizers.
