Polycarboxylate Superplasticizer Feem ntau yog copolymerized los ntawm unsaturated monomers nyob rau hauv qhov kev txiav txim ntawm cov neeg pib, thiab sab chains nrog active pab pawg yog grafted mus rau lub ntsiab saw ntawm lub polymer, thiaj li hais tias nws muaj lub luag hauj lwm ntawm high efficiency, tswj slump poob thiab shrinkage kuj, thiab tsis cuam tshuam rau coagulation thiab hardening ntawm cement. Polycarboxylic acid high-performance dej reducer yog txawv kiag li ntawm naphthalene sulfonate formaldehyde condensate NSF thiab melamine sulfonate formaldehyde condensate MSF dej reducer. Nws tuaj yeem ua rau cov pob zeb ua pob zeb muaj qhov fluidity siab txawm tias tsawg npaum li cas, thiab muaj cov viscosity tsawg thiab slump tuav kev ua tau zoo ntawm cov dej-cement piv. Nws muaj qhov zoo sib xws nrog cov cements sib txawv thiab yog ib qho khoom siv tsis tseem ceeb rau kev ua kom muaj zog thiab cov dej muaj kuab heev.

Polycarboxylate Superplasticizer yog lub cim thib peb ntawm kev ua haujlwm siab tshuaj dej reducer tsim tom qab ntoo calcium thiab naphthalene dej reducer. Piv nrog rau cov dej reducer, nws muaj cov hauv qab no zoo:

a. Kev txo cov dej siab: Cov dej txo qis ntawm polycarboxylic acid cov dej ua haujlwm siab tuaj yeem ncav cuag 25-40%.

b. Kev loj hlob ntawm lub zog loj: siab zog loj hlob tus nqi, tshwj xeeb tshaj yog thaum ntxov zog loj hlob tus nqi.

c. Kev tuav pov hwm zoo heev: Kev ua haujlwm ruaj khov zoo heev tuaj yeem ua kom lub sijhawm poob qis ntawm cov pob zeb.

d. Zoo homogeneity: Cov pob zeb npaj muaj fluidity zoo heev, yog ib qho yooj yim rau ncuav thiab compact, thiab yog haum rau tus kheej-leveling thiab nws tus kheej-compacting pob zeb.

e. Kev tswj xyuas ntau lawm: Cov dej txo qis, kev tuav pov hwm thiab kev ua haujlwm ntawm huab cua ntawm cov dej reducers no tuaj yeem hloov kho los ntawm kev kho cov khoom siv polymer molecular hnyav, qhov ntev, qhov ntom ntom thiab hom kev sib txuas ntawm pawg.

f. Dav adaptability: Nws muaj zoo dispersibility thiab yas tuav rau ntau yam ntshiab silicon, silicon dav, slag silicate cement thiab ntau yam admixtures los ua pob zeb.

g. Tsawg shrinkage: Nws tuaj yeem txhim kho qhov ntim ruaj khov ntawm cov pob zeb, thiab 28d shrinkage ntawm naphthalene-raws li dej reducer pob zeb yog txo los ntawm 20%, uas zoo txo qhov kev puas tsuaj los ntawm pob zeb tawg.

h. Ntsuab thiab ib puag ncig tus phooj ywg: non-toxic, non-corrosive, thiab tsis muaj formaldehyde thiab lwm yam khoom tsis zoo.
