Dab tsi yog qhov txawv ntawm PCE vs naphthalene raws li plasticizer?

Naphthalene raws li thiab polycarboxylic acid raws li kev ua haujlwm siab dej reducers yog ob hom kev sib xyaw thiab txhua tus muaj nws tus yam ntxwv. Naphthalene tau siv dav txij li nws tau tsim nyob rau xyoo 1962 los ntawm Dr Kenichi Hattori ntawm Hanada Ishikawa, Nyiv. Polycarboxylic acid dej reducer, ntawm qhov tod tes, tuaj ua ntej thaum xaus ntawm lub xyoo pua 20th. Nws muaj qhov txo qis dej ntau dua thiab hloov tau zoo dua rau cov ntaub ntawv cementitious, txo qis kev sib tsoo, muaj cov dej tso tawm qis dua thiab siv tsawg. Txawm li cas los xij, polycarboxylic acid kuj kim heev.

Thaum sib piv cov txiaj ntsig kev lag luam, koj yuav tsum tau tshawb xyuas cov txiaj ntsig kev xeem thiab cov nqi sib piv ntawm ob qhov sib xyaw ua ke. Yuav kom paub qhov chaw ntawm lawv cov khoom, koj tuaj yeem mus xyuas cov chaw xws li Jiangxi. Tsis tas li ntawd, muaj ntau hom kev sib xyaw ua ke, tsis yog tsuas yog cov dej txo qis, tab sis kuj tseem muaj lignocalcium thiab diamine resin systems. Ntawm cov no, qhov ntxov tshaj plaws lignosulphonate dej reducer tuaj yeem taug qab mus rau xyoo 1935.

Yog xav paub ntxiv thiab cov ntaub ntawv tshwj xeeb, nws raug nquahu kom koj sab laj nrog cov ntawv tshaj tawm txog kev lag luam lossis cov kws tshaj lij kev lag luam.

Naphthalene high-efficiency dej txo tus neeg saib xyuas, lub npe scientific ntawm naphthalene sulfonate formaldehyde condensate, yog ib qho tshuaj synthesis ntawm non-gas-entraining hom high-efficiency dej txo tus neeg sawv cev, cov cement hais muaj zog dispersing nyhuv ntawm kev npaj ntawm loj ndlwg qhob. muaj cov txiaj ntsig zoo heev ntawm kev npaj cov pob zeb loj loj muaj qhov cuam tshuam zoo heev ntawm cov cam khwb cia-hauv-qhov chaw ua vaj tse thiab prefabricated Cheebtsam nrog lub zog thaum ntxov, siab zog ntawm cov nyhuv yog pom tseeb, tuaj yeem txhim kho thiab txhim kho kev ua tau zoo ntawm pob zeb. , yog dav siv nyob rau hauv txoj kev loj, txuas hniav, dams, ports thiab harbours, tunnels, hluav taws xob fais fab, dej conservancy thiab civil engineering, chav curing thiab natural curing prefabricated Cheebtsam, thiab lwm yam. Nws yog dav siv nyob rau hauv txoj kev loj, txuas hniav, dams, ports, tunnels, hluav taws xob fais fab, kev txuag dej thiab kev lag luam thiab pej xeem engineering, chav kho thiab kev kho ntuj tsim ntawm cov khoom siv prefabricated.

I. Main technical indices (tsawg concentration ntawm naphthalene, high efficiency dej reducer)

1, Cov tsos: hmoov xim av-daj hmoov, kua xim av kua nplaum.

2, Cov ntsiab lus khoom: hmoov Ntau dua lossis sib npaug li 94%, kua ntau dua lossis sib npaug li 40%.

3, Net slurry flow Ntau dua lossis sib npaug li 230mm.

4, Sodium sulphate cov ntsiab lus Tsawg dua los yog sib npaug rau 10.

5, Chloride ion ntsiab lus Tsawg dua los yog sib npaug rau 0.5%.

Cov yam ntxwv ntawm kev ua haujlwm:

1, Thaum cov pob zeb ua kom muaj zog thiab poob qis yog qhov zoo ib yam, nws tuaj yeem txo cov cement los ntawm 10-25%.

2, Thaum cov dej-cement piv tsis hloov, qhov pib poob ntawm cov pob zeb tuaj yeem nce siab dua 10cm, thiab tus nqi txo cov dej tuaj yeem ncav cuag 15-25%.

3, Nws muaj qhov tseem ceeb thaum ntxov lub zog thiab kev txhim kho ntawm cov pob zeb, thiab nws lub zog nce yog 20-60%.

4, txhim kho qhov yooj yim ntawm pob zeb, txhim kho lub cev thiab lub zog ntawm cov pob zeb.

5, Nws muaj kev hloov tau zoo rau txhua yam ntawm cov cement thiab zoo sib xws nrog lwm hom kev sib xyaw ua ke.

6, tshwj xeeb tshaj yog tsim rau siv nyob rau hauv cov nram qab no pob zeb ua: kua pob zeb, plasticised pob zeb, autoclaved pob zeb, seepage-resistant pob zeb, waterproof pob zeb, natural curing precast qhob, reinforced thiab pre-stressed reinforced pob zeb, high-strength thiab ultra-high- lub zog pob zeb.
