Compound technical analysis:

1. Muaj teeb meem nrog niam cawv

Polycarboxylate dej-txo tus neeg saib xyuas yog ib hom tshiab ntawm cov dej-txo cov neeg ua haujlwm siab. Piv nrog rau cov tshuaj txo cov dej ib txwm muaj, nws muaj zog dispersibility nyob rau hauv cov pob zeb thiab muaj cov dej-txo tus nqi siab. Lub compounding ntawm cov dej-txo tus neeg sawv cev niam cawv tuaj yeem ua tiav rau qee yam. Kho qhov ntom ntawm cov khoom molecular sab chains, feem ntau hais lus, compounding ntawm niam cawv tuaj yeem ua tiav cov txiaj ntsig zoo. Ib leej niam cawv tuaj yeem sib xyaw nrog ntau tus niam cawv kom ua tiav nws txoj haujlwm, tab sis nws yuav tsum raug sau tseg tias cov khoom lag luam zoo, kev ua haujlwm siab monomer niam cawv yuav tsum tau xaiv. Tib lub sijhawm, polycarboxylic acid tsis tuaj yeem sib xyaw nrog qee cov tshuaj txo cov dej, xws li naphthalene series thiab aminoxantholate.

2. Cov teeb meem sib xyaw nrog lwm cov khoom xyaw ua haujlwm

Nyob rau hauv txoj kev tsim kho tiag tiag, txhawm rau daws cov teeb meem uas tau ntsib los ntawm qhov kev tsim kho, nws yog ib qho tsim nyog los txhim kho kev ua tau zoo ntawm cov pob zeb. Yog tias niam cawv ib leeg tsis tuaj yeem ua tau raws li qhov yuav tsum tau ua, qhov no, qee cov khoom siv me me, nrog rau cov thickeners, thiab lwm yam, yuav tsum tau ntxiv los txhim kho kev ua tau zoo ntawm pob zeb. . Retarder tuaj yeem muab ntxiv rau hauv pob zeb, uas yog cov khoom siv me me uas kho cov dej txo tus neeg sawv cev kom hloov mus rau lub sijhawm teeb tsa nyob rau hauv cov xwm txheej kub sib txawv. Ntxiv ib feem ntawm cov retarder yuav txo cov pob zeb tawg. Nyob rau tib lub sijhawm, thaum sib xyaw cov retarder, nws yuav tsum tau muab sau tseg tias cov retarder nws tus kheej muaj cov nyhuv txo cov dej, thiab qhov tseem ceeb no yuav tsum tau xav txog thaum lub sij hawm compounding txheej txheem ntawm cov dej-txo tus neeg sawv cev. Qhov teeb meem ntawm cov dej xau hauv pob zeb kuj tseem muaj nyob hauv cov haujlwm. Nyob rau hauv cov ntaub ntawv no, cov thickeners thiab air-entraining agents yuav siv tau los txhim kho qhov teeb meem, tab sis cov huab cua ntsiab lus ntawm cov pob zeb yuav tsum tau tswj kom tsim nyog, txwv tsis pub lub zog ntawm cov pob zeb yuav raug txo.
