Polycarboxylic acid dej tsim lub cav dej yog thawj cov ua dej ua kom muaj zog loj tsim thiab tsim tom qab naphthalene, melamine, aliphatic thiab aminosulfonate tshuab. Nws muaj cov yam ntxwv ntawm kev txo qis, cov dej ua kom siab dua, ua kom qis qis ntawm qhov qub, muaj peev xwm hloov tau zoo rau cov cement thiab cov shrinkage me me.
(1) Cov pa taws tawm: cov pa hluav taws xob uas tsis yog methane tag nrho hydrocarbon organic khib roj volatilized hauv cov reactor yog nqus los ntawm cov kua roj kaw (cov kua dej) thiab tom qab tshaj los ntawm 15m siab tso lub tog raj kheej adsorbed los ntawm cov roj carbon activated. Tsis tas li ntawd, cov pa tawm hauv chav ua haujlwm tau muaj zog los txo cov pa ntawm cov pa khib nyiab cov pa roj tawm ntawm cov reactor ntawm cov huab cua ib puag ncig.
(2) Kev siv dej ua paug: ncig ua kom cov dej txias, cov kua dej sib khi ntawm cov dej tsis huv, cov khoom siv ntxuav dej thiab lwm cov dej khib nyiab tau siv rau kev tsim khoom; rhiav kev tu cov dej hauv tsev thiab cov dej khib nyiab hauv tsev yog kho cov chaw lim dej kom huv thiab tso dej mus rau hauv cov chaw lim dej kom huv cov chaw pov dej, uas tsis muaj kev cuam tshuam me ntsis rau cov dej ib puag ncig.
(3) Lub Suab nrov: Cov khoom siv yuav tsum raug txo los ntawm kev ntsuas xws li kev nqus poob siab, teeb tsa thiab suab rwb thaiv tsev, thiab tuaj yeem ua tau raws li cov cai ntawm cov qauv ib puag ncig suab tom qab suab rwb thaiv tsev hauv lub rhiav.
(4) Cov khib nyiab: Cov khoom siv tsis zoo xws li cov pa roj carbon tshuab, ua kom muaj kuab lom thiab cov khoom tsis zoo, cov ntim khoom pov tseg thiab lwm cov khoom pov tseg hauv cov txheej txheem ntau lawm yog rov ua dua thiab pov tseg los ntawm cov chaw tsim khoom, thiab cov khoom seem ntawm cov khoom lag luam feem uas tau muag tawm Cov. Cov khib nyiab hauv tsev yog sau thiab muab cov khoom pov tseg ib puag ncig los ntawm kev tiv thaiv ib puag ncig chav tom qab chaw tsim khoom-chaw cia rau hauv lub hoobkas. Txhua yam khoom siv khib nyiab ntawm txoj haujlwm tau kho kom zoo thiab pov tseg.
