HIGH RANGE REDUCER (SMF)yog dej-soluble anion siab-polymer hluav taws xob nruab nrab.SMF muaj zog adsorption thiab decentralized nyhuv ntawm cov cement.SMF yog ib qho ntawm cov dej-schizes hauv cov pob zeb ua dej uas twb muaj lawm.Cov yam ntxwv tseem ceeb yog: dawb, dej siab txo tus nqi, tsis yog cua induction hom, cov ntsiab lus chloride ion tsawg tsis xeb ntawm steel tuav, thiab kev hloov tau zoo rau ntau yam cement.Tom qab siv cov dej txo tus neeg sawv cev, qhov kev siv zog thaum ntxov thiab permeability ntawm cov pob zeb tau nce ntxiv, kev tsim kho thiab kev tuav dej tau zoo dua, thiab kev kho chav dej tau hloov kho.
Nyob rau hauv lub pob zeb slump yog ib txwm zoo tib yam mob yuav txo tau qhov sib tov dej admixture hu ua high efficiency dej txo tus neeg sawv cev.Yog hais tias tus tib yam pob zeb slump, sib tov thiab dej noj yuav txo tau los ntawm ntau tshaj 15%.
Kev loj hlob keeb kwm:Thawj tiam ntawm high-efficiency dej txo tus neeg sawv cev thiab amine resin-based superplasticizer tau tsim nyob rau hauv thaum ntxov 1960s.Vim tias qhov kev ua tau zoo ntawm cov dej txo tus neeg sawv cev los ntawm lignesulfonate tau tsim nyob rau xyoo 1930s, nws tseem hu ua super plasticizer.Tus thib ob tiam high-efficiency dej txo tus neeg sawv cev yog amino sulfonate, txawm tias chronologically tom qab peb tiam ntawm superplasticizer - polycarboxylic kua qaub series.Lub graft copolymer nrog ob qho tib si sulfonic acid thiab carboxylic acid yog qhov tseem ceeb tshaj plaws nyob rau hauv lub thib peb tiam ntawm cov dej txo tus neeg saib xyuas, thiab nws cov kev ua tau zoo kuj yog qhov zoo tshaj plaws kev ua tau zoo dej txo tus neeg saib xyuas.
Hom loj:high efficiency dej txo tus neeg sawv cev dej txo tus nqi tuaj yeem ncav cuag ntau dua 20%.Nws yog feem ntau naphthalene series, melamine series thiab dej txo tus neeg sawv cev tsim los ntawm lawv, ntawm cov naphthalene series yog lub ntsiab, suav txog 67%.Tshwj xeeb, feem ntau ntawm cov dej ua haujlwm siab txo cov neeg ua haujlwm yog raws li naphthalene ua cov khoom siv tseem ceeb.Raws li cov ntsiab lus ntawm Na2SO4 hauv naphthalene series superplasticizer, nws 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 tsis muaj concentration (Na2SO4 cov ntsiab lus> 10%) .Feem ntau cov naphthalene 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 cov ntsiab lus ntawm NA2SO4 qis dua 0.4%.
Naphthalene series ntawm cov dej txo tus neeg sawv cev yog qhov loj tshaj plaws nyob rau hauv peb lub teb chaws ntau lawm, feem ntau siv dav siv dej txo tus neeg saib xyuas (sau ntau tshaj 70% ntawm cov dej txo tus neeg sawv cev), uas yog tus cwj pwm los ntawm kev txo cov dej siab (15%). ~ 25%), tsis muaj huab cua, me ntsis cuam tshuam rau lub sij hawm teem, kuj zoo adaptability nrog xis mas, yuav siv tau nrog lwm yam ntau yam additives compound, tus nqi kuj tseem pheej yig.Naphthalene superplasticizer feem ntau yog siv los npaj cov pob zeb nrog kev txav mus los, siab zog thiab kev ua haujlwm siab.Kev poob qis ntawm pob zeb nrog naphthalene superplasticizer sai dua.Tsis tas li ntawd, kev hloov pauv ntawm naphthalene series dej txo tus neeg sawv cev thiab qee cov cement yuav tsum tau txhim kho.
Khoom:Kev ua haujlwm siab dej txo tus neeg sawv cev muaj qhov cuam tshuam zoo rau cov cement, tuaj yeem txhim kho cov dej ntws ntawm cov cement sib xyaw thiab cov pob zeb ua pob zeb, thaum txo cov dej haus zoo, txhim kho kev ua haujlwm ntawm cov pob zeb.Tab sis qee qhov superplasticizer yuav ua rau kom poob qis ntawm cov pob zeb, sib xyaw ntau dhau yuav los ntshav.Kev ua haujlwm siab dej txo tus neeg sawv cev yeej tsis hloov lub sijhawm ua vaj tse, thiab muaj qhov cuam tshuam me ntsis thaum qhov ntau npaum li cas (dhau ntau npaum li cas), tab sis tsis ncua lub zog thaum ntxov ntawm cov pob zeb tawv tawv.
Nws tuaj yeem txo cov dej haus tau zoo thiab txhim kho lub zog ntawm cov pob zeb sib txawv ntawm cov hnub nyoog sib txawv.Thaum lub zog ruaj khov, cov cement tuaj yeem txuag tau 10% lossis ntau dua.
Cov ntsiab lus ntawm chloride ion yog me me, tsis muaj kev cuam tshuam corrosion ntawm steel bar.Nws tuaj yeem txhim kho qhov impermeability, khov-thaw tsis kam thiab corrosion kuj ntawm cov pob zeb, thiab txhim kho lub durability ntawm pob zeb.
APPLICATION:
1, Tsim nyog rau txhua yam kev lag luam thiab kev tsim kho vaj tse, kev txuag dej, kev thauj mus los, chaw nres nkoj, engineering precast thiab cam khwb cia-hauv-qhov chaw ntxiv dag zog.
2, Tsim nyog rau lub zog siab, lub zog siab siab thiab nruab nrab lub zog ua vaj tse, thiab cov kev xav tau ntawm lub zog thaum ntxov, nruab nrab Frost tsis kam, loj dej ua vaj tse.
3, Tsim nyog rau precast qhob cov tswv cuab ntawm chav kho txheej txheem.
4, Tsim nyog rau ntau yam kev sib xyaw ua ke ntawm cov dej-txo ntxiv dag zog (Master Batch).
