Qhov tseem ceeb rau cov kws muaj tswv yim: Cov lus qhia tshwj xeeb thiab hom polycarboxylate superplasticizylate superplasticizer & nws cov dej-txo mechanomism

Tsis muaj ib lub teb chaws sib koom ua ke lossis cov qauv kev lag luam npe rau cov cai thiab hom kev ua haujlwm polycarboxylate high ua kom txo cov neeg sawv cev. Lawv tuaj yeem muaj npe raws li lawv tus kheej cov yam ntxwv khoom, phiaj ua kev ua tau zoo thiab kev thov kev kos npe. Tus qauv feem ntau muaj cov ntaub ntawv hauv qab no:

• Hom Qauv / Hom Hom: Cov nqi txo qis yog ib txwm nyob ib ncig 20% ​​mus rau 25%.
• Cov hom dej ua haujlwm siab / cov dej txo qis: cov dej txo qis yog feem ntau 25% -30% lossis siab dua.
• Ultra-siab dej txo hom: cov dej txo qis tuaj yeem ncav cuag ntau dua 30%, thiab nws yog siv nyob rau hauv kev npaj ntawm ultra-siab lub zog uas yuav tsum muaj cov dej ntws tsawg kawg nkaus.
• Kev Tso Tawm qeeb-/ Slump Retient Toint: nws tshwj xeeb tshaj yog muaj peev xwm ua kom muaj kev poob qis (xws li tsim nyog rau kev thauj mus los ntev los yog kev siv kub siab.
• Lub zog thaum ntxov: thaum ua kom muaj zog txo tus nqi dej, nws tuaj yeem txhim kho lub zog thaum ntxov ntawm kev ua vaj tse.
• Anti-mud hom / anti-clay hom: nws muaj qhov zoo rau cov tshuaj uas rhiab xws li av nplaum thiab av nkos hauv cov qoob loo.

• Cov kua ua kua: Cov ntawv uas muaj ntau tshaj plaws, nrog rau kev sib haum xeeb (cov ntsiab lus muaj zog) feem ntau tau txij li 20% txog 50%. Kev pom zoo yog qhov tseem ceeb ntsuas.
• Hmoov: Feem ntau siv nyob rau hauv cov sijhawm tshwj xeeb (xws li cug cug qhuav, kev thauj mus los export, thiab lwm yam).

Qee hom yuav ncaj qha rau qhov tseem ceeb tshaj plaws, xws li "lub zog qeeb", "tiv thaiv kab mob qeeb", "Txo cov PC", "Txo cov PC", "Txo cov PC", "Kev txo lub PC", "Txo cov PC", "Txo cov PC", "Txo cov PC", "Txo cov PC", "Txo cov PC", "Txo cov PC", "Txo cov PC", "Txo cov PC", "Txo cov PC", "Txo cov PC", "

Nws tuaj yeem muaj cov ntaub ntawv ntsig txog cov qauv ntawm leej niam cawv (xws li muaj HPEG, Apeg, cov neeg siv tau piav qhia nyob rau hauv cov ntaub ntawv cov ntaub ntawv thiab tej zaum yuav tsis cuam tshuam hauv tus qauv).

Rau kev sib sau ua ke rau tus kheej lossis cov flu-fluity ua vaj tse, muaj ntau hom uas tsom rau kev txo cov viscosity thiab kev txhim kho flucity.

Ib puag ncig cov khoom lag luam ib puag ncig xws li formaldehyde-dawb thiab qis-alkali yuav muaj cov ntawv sau tshwj xeeb.

• Thov saib ncaj qha ntawm cov lus ntsuas kev sib piv! Thaum xaiv tus neeg sawv cev dej, qhov tseem ceeb tshaj plaws ntawm cov khoom siv, xws li siv cov khoom siv roj av, cov khoom siv me me, lub zog ua kom muaj zog, ua kom muaj zog ua kom muaj zog) Lub sijhawm sib txawv, shrinkage tus nqi piv, kev sib raug zoo ntawm cov cement, thiab lwm yam.

• Tham cov tswv yim txhawb nqa cov chaw tsim khoom: raws li cov kev tsim kho tshwj xeeb, kev tsim kho cov kev tsim kho, kev ua haujlwm ua kom zoo tshaj plaws thiab ntau yam tsim nyog.

Cov dej txo cov dej ntawm polycarboxylate superplasticizer yog txiav txim siab los ntawm nws cov qauv molecular. Cov tub ntxhais nyob hauv lub sticer cuam tshuam, ntxiv los ntawm electrostatic repulsion. Qhov no yog qhov sib txawv los ntawm kev ua yeeb yam naphhalene dej reducers (feem ntau yog cia siab rau electrostatic repulsion).

• Cov saw hlau tseem ceeb: feem ntau yog polymerized los ntawm monomers ntawm cov pab pawg acrylic lossis cov pab pawg accoth xws li cov pab pawg accox (-SO₃H)
• Sab saw: tsim ntawm ntev polyoxyylene ether (peo) saw (xws li HPEG, MPEG thiab lwm yam polyether macromonomers). Qhov no yog qhov tseem ceeb ntawm polycarboxylate superplasticer. Qhov ntev ntawm sab saw (molecular hnyav) thiab ntom ntom (grafting tus nqi) yog qhov tseem ceeb tshaj plaws.

1. Adsorption: cov pab pawg Aionic (cov pab pawg carboxyl, cov tsiaj muaj kua qaub thiab cov kab mob roj ntsha ua rau muaj kev sib cav sib ceg thiab kev sib tw hauv tshuab hluav taws xob, hydrogen kev sib koom tes lossis kev sib txuas hauv ionic.
2. Electrostatic repulsion: cov pawg anionic adsorbed ntawm lub ntsiab chansing rau ntawm cov xas tsis zoo ntawm cov lus thiab tiv thaiv lawv kom tsis txhob ya mus rau flocculation. Qhov no yog lub ntsiab mechanism ntawm cov dej tsoos dej.
3. Qhov chaw spatial steric cuam tshuam: qhov no yog qhov tseem ceeb tshaj plaws thiab kev txo dej kom txo tau dej ntawm polycarboxylate superplasticizer.
4. Lub polycarboxylic acid molecules adsorbed nyob rau saum npoo ntawm Maas hais yuav muaj lawv cov saw hlau hydrothet ntev ntev txuas ntxiv rau cov kua aqueous.
5. Thaum ob qho kev tso cai ua tiav cov dej ntws nrog cov dej ntws los ntawm cov tsiaj txhu ua ke, lawv ncua ntev txoj sia hlau yuav lub cev sib tshooj nyob rau hauv qhov chaw ntawm cov lus.
6. Qhov kev sib xyaw ua ke no cov kev sib xyaw ua ke ntawm cov saw hlau, txo qhov chaw tso nyiaj ntawm cov kab ke, thiab ua kom muaj zog quab yuam (entropy tsis muaj zog yuam kev).
7. Lub caij no, txoj sia ntev ntev lawv tus kheej kuj tsim lub cev lub cev, tabkaum kev sib tsoo ncaj qha thiab kev sib cuag ntawm cov lus.
8. Lub zog no tsis tsim txiaj tau tsim los ntawm kev sib txawv ntawm cov haujlwm ntawm polymer molecular yog hu ua Sterer thaiv cov nyhuv. Nws yog ntau ruaj khov thiab ruaj khov tshaj li Electrostatic repulsion (cuam tshuam tsawg dua los ntawm ionic lub zog hauv kev daws teeb meem ntse thiab tswj kom muaj kev sib cais ruaj khov (piv txwv li, ua kom qis dua).
9. Tso cov dej pub dawb: los ntawm Electrostatic rov ua haujlwm, yog qhov ua kom cov dej ntws dawb, piv txwv li cov khoom siv dawb tau ua kom tau cov dej qab zib uas yuav tsum tau ua kom tiav rau kev ua tiav cov dej flouric).

• Cov dej txo cov dej siab: Tus Sterer Bondage nyhuv muaj qhov ua tau zoo heev.
• Cov khau khiab zoo tshaj plaws: tus steric dhuav nyhav yog tsawg dua kev cuam tshuam los ntawm ion concentration, tsis yooj yim thaiv, thiab muaj ntau dhau kev sib tawg ua haujlwm.
• Tsawg ntau npaum li cas: nws lub siab molecular hnyav thiab sib xyaw ua ke kom ua kom nws ua tiav qhov kev cuam tshuam zoo heev ntawm cov tshuaj tsawg.
• Muaj zog ua qauv ntawm cov qauv molecular: los ntawm kev kho cov pa hluav taws xob saw cap, thiab faib tawm, thiab lub zog ntawm cov av nkos yuav tsum tau ua kom tau raws li cov kev xav tau ua ke.

To taub cov txheej txheem dej txo tau kom xaiv tau zoo dua thiab siv cov teeb meem polycarbox thiab daws cov teeb meem kev ua haujlwm ntawm cov pob zeb ua haujlwm.

Shanxi Jiankai zoo tshuaj muaj cov tshuaj ntau hauv zus tau tej cov qhob ua ke nrog ntau tshaj 20 xyoo.
