Cov tshuaj lom neeg raug xa mus rau cov tshuaj lom neeg thiab lwm yam tshuaj lom neeg, corrosive, explosive, flammable, combustion-txhawb thiab ua phem rau tib neeg lub cev, cov chaw thiab ib puag ncig.
High-efficiency dej-txo cov neeg ua haujlwm rau cov pob zeb feem ntau suav nrog naphthalene series, melamine series thiab cov dej-txo cov neeg ua haujlwm sib xyaw los ntawm lawv, ntawm cov naphthalene series yog lub ntsiab, suav txog 67%. Naphthalene series thiab melamine series tsis yog tshuaj lom neeg. Yog li ntawd, pob zeb superplasticizer tsis yog nyob rau hauv qeb ntawm cov tshuaj txaus ntshai.
Lub admixture uas tuaj yeem txo qhov sib xyaw dej ntim tau zoo nyob rau hauv cov xwm txheej uas cov pob zeb poob qis yog qhov zoo ib yam yog hu ua high-efficiency dej-txo tus neeg saib xyuas.
Cov dej-txo tus nqi ntawm cov dej-txo cov neeg ua haujlwm siab tuaj yeem ncav cuag ntau dua 20%. Nws yog tsim los ntawm naphthalene series, melamine series thiab dej-txo cov neeg ua hauj lwm compounded los ntawm lawv, ntawm cov naphthalene series yog lub ntsiab, accounting rau 67%. Tshwj xeeb tshaj yog nyob rau hauv Suav teb, feem ntau ntawm cov superplasticizers yog naphthalene series superplasticizers nrog naphthalene ua raw khoom. Naphthalene series superplasticizer tuaj yeem muab faib ua cov khoom siv siab (Na2SO4 cov ntsiab lus <3%), cov khoom nruab nrab concentration (Na2SO4 cov ntsiab lus 3% ~ 10%) thiab cov khoom siv qis (Na2SO4 cov ntsiab lus> 10%) raws li cov ntsiab lus ntawm Na2SO4 hauv nws cov khoom. . Feem ntau cov naphthalene series superplasticizer synthesis cov nroj tsuag muaj peev xwm tswj tau cov ntsiab lus ntawm Na2SO4 qis dua 3%, thiab qee qhov kev lag luam siab heev tuaj yeem tswj tau qis dua 0.4%.
Scope ntawm kev siv:
Nws yog siv rau precast thiab cam khwb cia-nyob rau hauv-qhov chaw reinforced pob zeb nyob rau hauv ntau yam industrial thiab civil vaj tse, kev txuag dej, tsheb thauj mus los, ports, municipal thiab lwm yam dej num.
Nws yog siv rau high-strength, ultra-high-strength thiab nruab nrab-lub zog pob zeb, nrog rau cov pob zeb uas yuav tsum tau muaj zog thaum ntxov, nruab nrab Frost tsis kam thiab siab fluidity.
Prefabricated qhob Cheebtsam haum rau cov txheej txheem ua kom sov.
Nws yog qhov tsim nyog rau kev ua dej-txo thiab ntxiv cov khoom siv (piv txwv li masterbatch) ntawm ntau cov khoom sib xyaw ua ke.
Tsis yog. Cov tshuaj phem yog cov khoom tawg. Txawm li cas los xij, feem ntau cov pob zeb superplasticizer tsis muaj cov khoom tawg thiab tawg, yog li cov pob zeb superplasticizer tsis yog cov tshuaj txaus ntshai.
