Cov tshuaj phom sij yog xa mus rau cov tshuaj lom neeg lom zem thiab lwm yam tshuaj lom uas muaj tshuaj lom, tawg, kev ua kom muaj kev phom sij rau tib neeg lub cev, chaw thiab ib puag ncig.
Cov neeg sawv cev dej siab-txo cov neeg sawv cev rau cov laj thawj yog suav nrog cov neeg sawv cev naphthalcing los ntawm lawv, ntawm cov neeg ua haujlwm metafhalene, metaphine series yog lub ntsiab, cov nyiaj txiag rau 67%. Naphthalene series thiab melamine series tsis muaj tshuaj phom sij. Yog li ntawd, qhob superplasticizer tsis yog qeb ntawm cov tshuaj muaj kuab lom.
Cov admixture uas tuaj yeem txo cov dej sib tov hauv qab cov mob uas cov swb ntawm cov khoom siv ua haujlwm zoo ib yam yog ua rau tus neeg saib xyuas dej siab.
Cov dej ntws-txo tus nqi ntawm cov dej ntws loj-ua kom tus neeg sawv cev muaj peev xwm ncav cuag ntau dua 20%. Nws yog tsuas yog tsim los ntawm naphthalene series, melamine series thiab txo cov neeg sawv cev sib xyaw los ntawm lawv, ntawm cov naphthalene series yog lub ntsiab, kev suav nyiaj rau 67%. Tshwj xeeb tshaj yog nyob rau hauv Suav teb, feem ntau ntawm superplasticizers yog naphthalene series superplasticizers nrog naphthalene raws li cov khoom tseem ceeb. Naphthalal Series SuperPlasticizer tau muab faib ua cov khoom lag luam siab (na -so4 cov ntsiab lus> 10%) raws li cov ntsiab lus ntawm NA2% hauv nws cov khoom Cov. Feem ntau Naphthalene Series Superplasticier synthesis nroj tsuag muaj lub peev xwm los tswj cov ntsiab lus ntawm na2s4, thiab qee cov lag luam siab dua tuaj yeem tswj nws hauv qab 0.4%.
Cov tau txais daim ntawv thov:
Nws yog siv rau precast thiab cas-nyob rau hauv-chaw txhawb nqa qhob thiab vaj tse, cov chaw tsheb thauj mus los, chaw nres nkoj, hauv nroog thiab lwm yam dej num.
Nws yog siv rau high-zog, ultra-lub zog thiab nruab nrab lub zog qhob, ntxiv rau cov khoom ua kom ntxov, nruab nrab khov ua thiab siab fluidity.
Prefabricated qhob Cheebtsam haum rau chav kho khaub ncaws.
Nws yog qhov haum rau kev ua dej-txo thiab txo cov khoom siv (piv txwv li masterbatch) ntawm ntau yam compjectures.
Tsis zwm rau. Cov tshuaj phom sij yog cov khoom pov tseg. Txawm li cas los xij, dav hlau ruaj ruaj superplasticizer tsis muaj cov khoom tawg thiab tawg, yog li cov qhob superplasticizer tsis yog cov tshuaj uas txaus ntshai.
