7. Marka admixture polycarboxylic acid lagu tijaabiyo isku dhafan (wax soo saarka), marka kaliya qiyaasta aasaasiga ah la gaaro, waxqabadka bilowga ah ee shaqada ee la taaban karo ayaa lagu qancin doonaa, laakiin khasaaraha la taaban karo ayaa ka weynaan doona; sidaas darteed, inta lagu jiro isku darka tijaabada (wax soo saarka), qadarka waa in si habboon loo kordhiyo. Kaliya marka la hagaajiyo qiyaasta (taas oo ah, gaaritaanka qiyaasta qiyaasta) ayaa la xalin karaa dhibaatada weyn ee luminta.

8.Ka dib markii la yareeyo tirada alaabta sibidhka, saamiga biyaha-sibidhka waa in si adag loo hubiyo inta lagu jiro habka wax soo saarka. Haddii khasaaruhu weyn yahay, habka kaliya ayaa ah in la kordhiyo qadarka isku-darka oo lagu daro isku-darka laba jeer. Ha ku darin biyaha si aad u xalliso dhibaatada, haddii kale waxay si fudud u keeni doontaa hoos u dhac weyn oo xoogga ah.

9. Polycarboxylate wakiilka biyaha dhimaya waa badeecad leh heerar sare oo hoos u dhigista biyaha iyo kala firidhsanaan sare. Xakamaynta wax-soo-saarka, tusaha dareeraha (ballaarinta) ee shubka waa in loo adeegsadaa si loo cabbiro kartida shaqada ee shubka. Burburinta waxa kaliya loo isticmaali karaa qiime tixraac ahaan.

10. Xoogga shubka waxaa inta badan lagu go'aamiyaa saamiga biyaha-xidhaha. Wakiilka biyaha yareeya ee Polycarboxylate wuxuu leeyahay sifooyinka heerka sare ee hoos u dhigista biyaha, kaas oo si fudud u yarayn kara isticmaalka biyaha ee saamiga isku dhafka ah ee wax soo saarka, taas oo lagu gaadhayo ujeedada dhimista saamiga biyaha-xidhaha iyo yaraynta xoogga shubka. kharash dhamaystiran. Maaddaama alaabada cayriin ay u badan tahay inta lagu jiro wax soo saarka marka loo eego inta lagu jiro baaritaanka, si si fiican looga faa'iidaysto waxqabadka alaabada superplasticizer polycarboxylate, admixtures waa in lagu hagaajiyaa hab waqtigeeda ah iyadoo loo eegayo saameynta xaaladaha alaabta ceeriin, isbeddelka heerkulka jawiga, iwm. la taaban karo inta lagu jiro wax soo saarka. Qiyaasta

11. Aashitada Polycarboxylic ee biyaha-yaraysa laguma qasi karo walxaha biyaha-yareeya ee ku salaysan naphthalene. Marka la isticmaalayo maaddooyinka biyaha-yareeya ee polycarboxylic acid, qaseeyaha iyo gaadhi-guud ee isticmaalay maaddooyinka biyo-yareeya ee naftalale-ku-salaysan waa in si nadiif ah loo dhaqaa, haddii kale waxa laga yaabaa in wax-yeello gaadho wakiilka biyaha-yareeya ee polycarboxylic acid. Wakiilka biyaha yareeya wuxuu lumiyaa saameyntiisa yaraynta biyaha.

12. Polycarboxylate superplasticizer waa in uu ka fogaadaa xidhiidhka muddada dheer ee walxaha birta ah. Maadaama polycarboxylate-ka wax-soo-saarku uu inta badan yahay acidic, xidhiidhka muddada-dheer ee alaabta birta waxay keeni doontaa falcelin gaabis ah, taas oo laga yaabo inay xitaa madoobaato ama madoobaato midabka, taasoo keentay hoos u dhaca waxqabadka alaabta. Waxaa lagu talinayaa in la isticmaalo baaldiyada caagga ah ee polyetylen ama baaldiyada birta ah ee birta ah ee kaydinta si loo hubiyo xasilloonida waxqabadka.
