Cov dej pob zeb txo tus neeg sawv cev yog ib txoj hauv kev los txo cov cement ntau npaum, txhim kho kev siv cov khoom pov tseg, thiab paub txog kev ua haujlwm ntev thiab kev ua haujlwm siab ntawm pob zeb.Nws kuj yog ib qho ntawm cov ntaub ntawv tseem ceeb rau txoj kev loj hlob ntawm pob zeb rau high-tech teb.Thiab polycarboxylate hom dej txo tus neeg saib xyuas (PC) tau dhau los ua ib hom dej txo tus neeg sawv cev nrog kev txhim kho sai tshaj plaws thiab kev ua lag luam loj tshaj plaws vim nws tsis muaj tshuaj lom thiab tiv thaiv ib puag ncig.Piv nrog rau cov tsoos admixtures, cov admixtures tau dhau los ua qhov tseem ceeb ntawm kev tshawb fawb thoob ntiaj teb thiab kev txhim kho vim tias lawv cov dispersibility zoo heev thiab muaj peev xwm khaws cia.
Txawm hais tias polycarboxylate dej txo cov kev sib xyaw ua tau zoo tshaj plaws thiab muaj peev xwm tswj tau qhov kev poob zoo tau raug lees paub, tab sis vim tias muaj cov ntxhia hauv cov ntxhia, cement fineness, cement plaster form thiab cov ntsiab lus, cov khoom sib xyaw ntxiv, thiab cov txheej txheem sib xyaw ntawm cov pob zeb sib xyaw, dej. muaj lub siab rhiab heev, cuam tshuam rau cov khoom uas twb muaj lawm yog dav siv hauv engineering.
Polycarboxylate Series Dej txo tus neeg sawv cev yog dab tsi?
Polycarboxylate superplasticizer yog ib hom surfactant uas muaj carboxylic graft copolymer.Nws cov molecules yog zuag zoo li tus thiab muaj siab steric hindrance nyhuv.Raws li lub cim thib peb ntawm kev ua haujlwm siab dej txo tus neeg sawv cev tom qab lignosulfonate cov dej txo qis tus neeg saib xyuas, naphthalene series aliphatic pab pawg, sulfamate thiab lwm yam dej txo cov neeg ua haujlwm siab.
Nws yog vim hais tias ntawm cov qauv molecular tsim kev ua tau zoo, siab txo dej, tsis tshua muaj admixture tus nqi, ua kom slump zoo, txhim khu zoo, muaj alkali npaum li cas tsawg, teem sij hawm cuam tshuam me me, thiab feem ntau cement compatibility yog zoo thiab tsis muaj kuab paug. Lwm qhov zoo yog suav tias yog qhov kev loj hlob tshaj plaws ntawm cov dej txo tus neeg sawv cev ntau yam.
Polycarboxylate superplasticizer yog ib tug tshiab high-efficiency superplasticizer tsim thiab ua tiav tom qab naphthalene, melamine, aliphatic thiab sulfamate superplasticizer.Nyob rau hauv nws cov ntsiab lus tsis tshua muaj (cov ntsiab lus ntawm 0.15% - 0.25%) tuaj yeem tsim cov dej zoo tshaj plaws kom txo tau thiab txhim kho cov nyhuv, tsis tshua muaj kev cuam tshuam rau lub sij hawm ntawm kev ua vaj tse thiab slump tuav, adaptability rau cement thiab admixture yog qhov zoo, muaj kev cuam tshuam me me ntawm kev ziab. shrinkage ntawm pob zeb (feem ntau tsis dhau ua kom qhuav shrinkage), tsis siv cov formaldehyde hauv cov txheej txheem ntawm kev tsim khoom thiab tsis tso cov dej cawv pov tseg, SO Cov ntsiab lus qis ntawm 42- thiab Cl- tau txais kev qhuas los ntawm cov kws tshawb fawb thiab qee cov neeg siv txij thaum pib.
Vim li cas thiaj yuav tsum tau hloov kho Polycarboxylate Superplasticizer?
Piv nrog naphthalene series siab npaum dej txo tus neeg saib xyuas, xws li, txawm hais tias poly carboxylic acid dej txo tus neeg saib xyuas hauv kev txo cov dej txuag dej muaj qhov zoo ntawm kev tiv thaiv ib puag ncig, tab sis muaj qee qhov teeb meem hauv kev siv engineering, xws li dej txo cov nyhuv ntawm cov khoom siv raw, sib tov piv, dej txo tus neeg saib xyuas kev noj qab haus huv yog qhov loj heev, cov qhob tshiab ua tau zoo yog rhiab rau cov dej haus, yooj yim npaj ntawm cov dej loj sib cais txheej.Tsis zoo sib xws nrog lwm cov dej-txo cov neeg ua hauj lwm thiab hloov cov khoom thiab cov khoom tsis zoo ruaj khov heev txwv tsis pub siv dav thiab kev loj hlob ntawm polycarboxylate dej-txo cov neeg ua haujlwm.
Txhawm rau kov yeej cov kev tsis zoo hauv kev siv cov tshuaj polycarboxylate dej-txo tus neeg saib xyuas, lossis txhawm rau txhim kho qee qhov lossis qee yam khoom ntawm pob zeb (ua haujlwm tau zoo, kev tuav cia, txo cov ntshav, txhim kho lub zog thaum ntxov, qis qis, thiab lwm yam), nws yog tsim nyog los hloov cov pob zeb.
Hauv kev xyaum, cov kev hloov kho feem ntau suav nrog cov cuab yeej siv hluav taws xob thiab cov cuab yeej sib txuas.Piv nrog rau cov txheej txheem hluavtaws, cov txheej txheem sib xyaw ua ke muaj qhov zoo ntawm kev ua haujlwm yooj yim thiab tus nqi qis, yog li nws tau siv dav hauv kev siv tswv yim.Polycarboxylate series compound technology, yog polycarboxylate series dej-txo tus neeg saib xyuas thiab lwm yam khoom siv (xws li coagulation qeeb, defoamy, cua induction, thaum ntxov zog thiab lwm yam khoom siv) raws li ib feem ntawm kev sib xyaw ua ke, thiaj li ua tiav kev sib koom tes ntawm lub superposition ntawm txhua yam.
