High RANGE WATER REDUCER(SMF)ndi madzi -sungunuka anion mkulu - polima magetsi sing'anga. SMF ili ndi ma adsorption amphamvu komanso kugawa kwa simenti. SMF ndi imodzi mwama schizes omwe alipo mu konkire yochepetsera madzi. Zomwe zili zazikulu ndi izi: zoyera, kuchuluka kwamadzi ochepetsera madzi, mtundu wosakhala ndi mpweya, ma ion otsika a chloride samachita dzimbiri pazitsulo zachitsulo, komanso kusinthika kwa simenti yosiyanasiyana. Pambuyo pogwiritsira ntchito mankhwala ochepetsera madzi, mphamvu yoyambirira ndi kuphulika kwa konkire inakula kwambiri, zomangamanga ndi kusunga madzi zinali bwino, ndipo kukonza nthunzi kunasinthidwa.
Mu konkire slump kwenikweni ndi mkhalidwe womwewo akhoza kwambiri kuchepetsa kusakaniza madzi admixture wotchedwa mkulu dzuwa kuchepetsa agent.Pankhani ya yemweyo konkire slump, kusakaniza ndi kumwa madzi akhoza kuchepetsedwa ndi oposa 15%.
Chitukuko mbiriyakale:M'badwo woyamba wa zochepetsera zochepetsera madzi komanso amine resin-based superplasticizer zidapangidwa koyambirira kwa zaka za m'ma 1960. Chifukwa cha ntchito wamba madzi kuchepetsa wothandizila ndi lignesulfonate anayamba chakumapeto kwa zaka za m'ma 1930, amatchedwanso wapamwamba plasticizer.The m'badwo wachiwiri mkulu -mwachangu kuchepetsa wothandizila madzi ndi amino sulfonate, ngakhale nthawi pambuyo m'badwo wachitatu superplasticizer - polycarboxylic asidi mndandanda. The graft copolymer yokhala ndi sulfonic acid ndi carboxylic acid ndiyofunikira kwambiri m'badwo wachitatu wazochepetsera madzi, ndipo magwiridwe ake ndinso njira yabwino kwambiri yochepetsera madzi.
Mitundu yayikulu:Kugwiritsa ntchito bwino kwambiri kuchepetsa madzi ochepetsa madzi kumatha kufika kuposa 20%. Ndiwo mndandanda wa naphthalene, mndandanda wa melamine ndi wothandizira kuchepetsa madzi omwe amapangidwa ndi iwo, omwe ndi naphthalene mndandanda waukulu, womwe umawerengera 67%. Makamaka, zida zambiri zochepetsera madzi zimachokera ku naphthalene monga zopangira zazikulu. Malinga ndi zomwe zili Na2SO4 mu superplasticizer ya naphthalene, imatha kugawidwa m'magulu akuluakulu (Na2SO4 okhutira <3%), mankhwala apakati (Na2SO4 okhutira 3% -10%) ndi mankhwala otsika ndende (Na2SO4 okhutira> 10%). Ambiri naphthalene superplasticizer kaphatikizidwe zomera amatha kulamulira zili Na2SO4 m'munsimu 3%, ndi ena mabizinezi zapamwamba akhoza ngakhale kulamulira zili NA2SO4 pansipa 0,4%.
Naphthalene mndandanda wa madzi kuchepetsa wothandizila ndi yaikulu kwambiri m'dziko lathu kupanga, ambiri ntchito kwambiri kothandiza kuchepetsa wothandizila madzi (kuwerengera oposa 70% ya kuchuluka kwa madzi kuchepetsa wothandizila), amene yodziwika ndi mkulu mlingo kuchepetsa madzi (15% ~ 25%), palibe mpweya, zotsatira pang'ono pa nthawi yoika, ndi bwino kusinthasintha ndi simenti, ndi zina mtengo wotchipa, komanso wotchipa pawiri, angagwiritsidwe ntchito pawiri zosiyanasiyana. Naphthalene superplasticizer nthawi zambiri imagwiritsidwa ntchito pokonzekera konkire ndikuyenda kwambiri, mphamvu yayikulu komanso magwiridwe antchito apamwamba. Kuwonongeka kwa konkire ndi naphthalene superplasticizer ndikofulumira. Kuphatikiza apo, kusinthika kwa naphthalene mndandanda wochepetsera madzi ndi simenti ina kuyenera kuwongolera.
Katundu:mkulu dzuwa kuchepetsa wothandizila ali amphamvu kubalalitsidwa tingati pa simenti, akhoza kwambiri kusintha otaya kusakaniza simenti ndi kugwa konkire, pamene kwambiri kuchepetsa kumwa madzi, kwambiri kusintha workability konkire. Koma superplasticizer ina imafulumizitsa kutayika kwa konkire, kusakaniza kochuluka kumatulutsa madzi. Kugwiritsa ntchito bwino kwambiri kuchepetsa madzi kwenikweni sikumasintha nthawi yoyika konkriti, ndipo kumakhala ndi kuchedwetsa pang'ono pamene mlingo uli waukulu (kuphatikiza mlingo), koma sikuchedwetsa kukula kwamphamvu koyambirira kwa konkire yowumitsidwa.
Ikhoza kuchepetsa kwambiri kumwa madzi ndikuwongolera kwambiri mphamvu ya konkire pazaka zosiyanasiyana. Mphamvu ikasungidwa nthawi zonse, simenti imatha kupulumutsidwa ndi 10% kapena kuposa.
Zomwe zili mu chloride ion ndizochepa, palibe dzimbiri pazitsulo zachitsulo. Itha kupititsa patsogolo kusasunthika, kukana kuzizira kwa konkriti ndi kukana kwa dzimbiri, ndikuwongolera kulimba kwa konkriti.
APPLICATION:
1,Yoyenera mitundu yonse ya zomangamanga zamafakitale ndi zachitukuko, zosungira madzi, zoyendera, doko, zomangamanga zamatauni ndi konkriti yolimba.
2, Oyenera mphamvu mkulu, kopitilira muyeso mkulu ndi sing'anga mphamvu konkire, ndi zofunika mphamvu oyambirira, zolimbitsa chisanu kukana, lalikulu liquidity konkire.
3, Oyenera mamembala a precast konkire a njira yochiritsa nthunzi.
4, Yoyenera kuphatikizika kwamitundu yosiyanasiyana yazinthu zochepetsera madzi (Master Batch).
