Kev Tswj Xyuas Zoo

Polycarboxylate superplasticizer (pceplasticizer (pceplasticizer (PCE) yog qhov ua tau zoo txhim kho lub zog, lub zog thiab kev ua haujlwm ruaj khov. Vim nws cov qauv molecular, cov txheej txheem ntau lawm cuam tshuam nrog kev xaiv ntau yam xws li kev tswj cov tshuaj, kev tswj hwm nruj heev yog qhov tseem ceeb. Cov hauv qab no yog qhov tseem ceeb tswj kev ntsuas hauv cov txheej txheem ntau lawm ntawm polycarboxylate superplasticizer:

1. Cov Khoom Siv Raw Khoom Zoo (IQC)
Cov ntaub ntawv nyoos ntawm polycarboxylate superplasticizer muaj:

MacRomonomers (xws li HPEG, TPEG, EPEG, thiab lwm yam):cuam ​​tshuam rau cov dej txo cov dej thiab kev ua tau zoo, thiab yuav tsum tau sim purity, hnyav hnyav, thiab lwm yam.

Acrylic acid (AA) lossis lwm yam me me monomers:Xav tau los tswj kev coj huv, acid tus nqi, thiab inhibitor cov ntsiab lus.

Tus pib (xws li ammonium persulfate, v -50}, thiab lwm yam):Tshawb pom cov ntsiab lus oxygen kom ntseeg tau tias cov tshuaj tiv thaiv polymerization.

Tus neeg sawv cev hloov mus (xws li cov kua roj thioglycolic acid, mercaptopocionic acid):cuam ​​tshuam cov molecular phaus faib, thiab cov lus piv tau xav tau nruj me ntsis tswj tau.

Neutralizer (xws li Naoh, Koh):Kos suab kom tsis txhob impurities cuam tshuam rau cov khoom muaj kev ruaj ntseg.

Txoj Kev Tswj:

Cov khoom xa tawm los xyuas kom ntseeg tau tias cov khoom siv tau zoo ntawm cov khoom siv raw.

Txhua pob yog kuaj thaum nkag mus rau lub Hoobkas thiab tsuas siv tau tom qab ntsib cov qauv.

Cov cim tseem ceeb tau txheeb xyuas los ntawm cov roj chromatography (GC), kua chromatography (HPLC), thiab lwm yam.

2. Ntau Lawm Txheej Txheem Tswj (IPQC)

(1) cov tshuaj tiv thaiv kev tswj hwm

Tswj kub: Cov tshuaj tiv thaiv kub: cov tshuaj tiv thaiv cua sov yog tswj kom tsis txhob raug tswj kom tsis txhob muaj qhov ntsuas kom tsis txhob muaj qhov ua kom tsis txhob muaj kev tiv thaiv hauv cheeb tsam thiab sab nraud.

PH Hloov Kho: Cuam tshuam cov tshuaj tiv thaiv tus nqi thiab cov qauv molecular, thiab yog cov tshuaj xyuas thiab kho tau nyob rau lub sijhawm tiag tiag.

Cov txheej txheem dej nrog: Monomers thiab cov pib feem ntau yog pub los ntawm dripping los xyuas kom ntseeg tau cov tshuaj tsis zoo thiab zam kev ua nruj ua tsiv polymerization.

Lub sijhawm dhau los: ntev dhau yuav ua rau muaj kev hnyav heev, thiab luv luv yuav ua rau muaj kev hloov pauv tsis txaus, yog li cov txheej txheem yuav tsum tau ua kom zoo.

Txoj Kev Tswj Xyuas:

Kev soj ntsuam online online thiab ntsuas kub rau kev soj ntsuam kev saib xyuas tiag tiag.

Kev ua piv txwv ib txwm mus kuaj cov ntsiab lus tawv, viscosity, tus nqi hloov dua siab tshiab, thiab lwm yam.

(2) phaus hnyav thiab cov qauv molecular tswj
GPC (gel per wormation chromatography):Txheeb xyuas qhov hnyav uas faib kom ntseeg tau cov khoom lag luam ruaj khov.

Infrared spectroscopy (FTIR):Txheeb xyuas cov pab pawg neeg ua haujlwm kom ua tiav polymerization ua tiav.

3. Ua tiav cov khoom lag luam zoo tswj (FQC / OQC)
(1) Cov Khoom Siv Khoom Siv Kev Siv Tshuaj Mob
Cov ntsiab lus nyuaj
PH nqi
Ceev
(2) pob zeb ua haujlwm ntsuas
Dej txo tus nqi
Slump Letention
Teem Sijhawm
Compressive muaj zog piv: 7d thiab 28d lub zog yuav tsum ua kom tau raws cov qauv.

4. Kev khaws cia thiab kev thauj mus los tswj hwm
Cov tshuaj antifrouel thiab qhov kub siab: zam qhov kub me crystallization lossis siab qhov kub.
Anti Mildew: Ntxiv qhov tsim nyog ntawm cov tshuaj tiv thaiv (xws li isothiazoline).
Anti nag lossis tsis tu ncua lossis siv homogenizing tshuab.

5. Cov Txheej Txheem Tswjhwm Zoo
ISO 9001 Ntawv pov thawj: Tsim cov txheej txheem ntau lawm.

Tag
Qhov kev tswj hwm zoo ntawm polycarboxylic acid muaj reducer cuam tshuam nrog ntau qhov txuas, cov kev tshuaj tiv thaiv cov txheej txheem, kev ntsuas tiav thiab kev tswj khoom. Los ntawm txoj kev nruj me ntsis, cov qauv kev ntsuas siab dua thiab peb tuaj yeem ua kom paub meej tias cov khoom lag luam ruaj khov thiab ua tau cov qauv siab ntawm kev ua vaj tse siab.
