1. Shabka leh dheecaan sare waxay u nugul yihiin delamination iyo kala soocidda.
Xaaladaha intooda badan, shubka dareeraha sare leh ee lagu diyaariyey wakiilada biyaha yareeya ee polycarboxylic acid ma keenayaan dhiigbax isku dhafka shubka ah xitaa haddii qadarka biyaha yareeya iyo isticmaalka biyaha si fiican loo xakameeyo, laakiin aad bay u fududahay in la sameeyo. Ifafaalayaasha kala soocida iyo kala soocida waxay ka muuqdaan quusitaanka wadar aan dhab ahayn iyo sabayn hoobiye ama dareere saafi ah. Marka nooca isku dhafka ah ee la taaban karo loo isticmaalo shubitaanka, delamination iyo kala soocida waa caddahay xitaa iyada oo aan gariir lahayn.
Sababtu waxay inta badan sabab u tahay hoos u dhaca ba'an ee viscosity of slurry marka dheecaanka shubka ee lagu dhex daray wakiilkan biyo-yaraynta ku salaysan ee polycarboxylic uu sarreeyo. Isku-darka ku habboon ee qaybaha dhumucdiisu waxay xallin kartaa dhibaatadan ilaa xad, iyo isku-darka qaybaha dhumucda inta badan waxay keentaa falcelinta si dhab ah u yaraynta saamaynta biyaha yaraynta.
2. Marka lala isticmaalo noocyada kale ee wakiilada biyaha yareeya, ma jiraan wax saamayn ah oo korka kaca ah.
Waagii hore, marka la diyaarinayo shubka, nooca wakiilka bamgareynta waa la bedeli karaa sida la rabo, iyo sifooyinka isku dhafka shubka kama duwanaan doono natiijooyinka shaybaarka, mana jiri doono isbeddel lama filaan ah oo ku yimaada sifooyinka isku dhafka shubka ah. .
Marka wakiilada biyaha yareeya ee polycarboxylic acid lagu daro noocyada kale ee wakiilada biyaha-yareeya, way adagtahay in la helo saamayn sare, iyo milanka wadaagga ah ee u dhexeeya xalalka wakiilada biyaha yareeya ee ku salaysan polycarboxylic acid iyo noocyada kale ee biyaha. yaraynta xalalka wakiilku waa mid liita.
3. Ma jirto wax saameyn ah oo wax ka beddel ah ka dib marka lagu daro qaybaha wax ka beddelka ee inta badan la isticmaalo.
Waqtigan xaadirka ah, waxaa jira maalgashi yar oo cilmi baaris ah oo ku saabsan wakiilada biyaha yareeya ee polycarboxylic acid. Xaaladaha intooda badan, hadafka cilmi-baarista cilmi-baarista waa kaliya in la sii wanaajiyo balaastigga iyo saameynta biyaha-yaraynta. Way adag tahay in la naqshadeeyo qaab-dhismeedka molecular iyadoo loo eegayo baahiyaha injineernimada ee kala duwan. Taxane biyo-dhimis ah oo ku salaysan polycarboxylic acid oo leh dib-u-dhac iyo dardargelin kala duwan, ma jiraan wax hawo-mareen ama waxyaabo hawo-marineed oo kala duwan, iyo muuqaallo kala duwan ayaa la farsameeyay. Sababtoo ah kala duwanaanshaha iyo xasilloonida sibidhka, isku-darka, iyo isku-darka mashaariicda, aad bay muhiim ugu tahay soo-saareyaasha wax-soo-saarka iyo alaab-qeybiyeyaasha si ay isugu daraan oo ay u beddelaan polycarboxylate-biyo-yaraynta alaabada isku-dhafka ah iyadoo loo eegayo baahiyaha mashruuca.
Waqtigan xaadirka ah, tillaabooyinka farsamada ee wax ka beddelka isku dhafka ah ee wakiilada biyaha yareeya waxay asal ahaan ku saleysan yihiin cabbirada wax ka beddelka ee wakiilada biyaha yareeya sida taxanaha lignosulfonate iyo taxanaha naphthalene ee waxtarka sare leh ee biyaha yareeya. Tijaabooyinku waxay caddeeyeen in tillaabooyinka farsamada wax ka beddelka ee hore aanay daruuri ku habboonayn wakiilada yaraynta biyaha ee polycarboxylic acid. Tusaale ahaan, ka mid ah qaybaha dib u dhigista ee loo isticmaalo in lagu beddelo wakiilada biyaha yareeya ee ku salaysan naphthalene, sodium citrate kuma habboona wakiilada biyaha yareeya ee polycarboxylic acid. Ma aha oo kaliya ma laha saameyn dib-u-dhac ah, waxay soo dedejin kartaa xinjirowga, iyo xalalka sodium citrate The miscibility with polycarboxylic acid-based water-based agents sidoo kale waa mid aad u liidata.
Intaa waxaa dheer, noocyo badan oo ah wakiilada xumbo-samaynta, wakiilada hawo-ku-jiidhiyaha iyo dhumucyada ayaan ku haboonayn wakiilada yaraynta biyaha ee polycarboxylic acid. Iyada oo loo marayo tijaabooyinka kor ku xusan iyo falanqaynta, ma adka in la arko in ay sabab u tahay gaar ah ee qaab-dhismeedka molecular ee polycarboxylic acid-ku salaysan biyo yaraynta wakiilada, oo ku salaysan qoto dheer ee cilmi-baarista sayniska iyo ururinta ee codsiga injineernimada marxaladdan, saamaynta ee wakiilada biyaha yareeya ee polycarboxylic acid ee superplasticizers-ku salaysan polycarboxylic acid iyada oo loo marayo qaybo kale oo kiimiko ah Ma jiraan siyaabo badan oo wax looga beddelo wakiilada biyaha yareeya, iyo iyadoo ay ugu wacan tahay aragtiyaha iyo heerarka la aasaasay waagii hore ee wax ka beddelka noocyada kale ee yaraynta biyaha. wakiilada, sahaminta qoto dheer iyo cilmi baarista ayaa laga yaabaa in loo baahdo wakiilada biyaha dhimaya ee polycarboxylate. Samee sixid iyo kordhin.
4. Xasiloonida waxqabadka alaabadu aad bay u liidataa.
Ma badna shirkado badan oo la taaban karo oo biyo-yareeya oo isku dhafan oo si dhab ah loogu tixgalin karo shirkado kiimiko oo wanaagsan. Shirkado badan ayaa kaliya ku sii jira heerka wax soo saarka aasaasiga ah ee isku-darka iyo mashiinnada baakadaha, tayada badeecaduna waxay xaddidan tahay tayada masterbatch. Ilaa hadda sida xakamaynta wax soo saarka, xasiloonida ilaha iyo tayada alaabta ceeriin ayaa had iyo jeer ah arrin weyn oo dhibaysa waxqabadka superplasticizers-ku salaysan polycarboxylic acid.
