Polycarboxylate superplasticizer waa jiilka saddexaad ee wax qabad heer sare ah oo la sameeyay ka dib caagagga caadiga ah ee uu matalo kaalshiyam alwaax ah iyo superplasticizer-ka uu matalayo taxanaha naphthalene.
Polycarboxylate ku salaysan superplasticizer hadda waa wax-ku-oolnimada sare ee biyaha yareeya oo leh nuxurka sayniska iyo tignoolajiyada ugu sarreeya, rajada codsiga ugu fiican, iyo waxqabadka ugu wanaagsan ee dhammaystiran.Kiimikada PCE sidoo kale waa taxane biyo dhimis ah oo leh waxqabad aad u wanaagsan oo isku dhafan biyo-yaraynta, haynta slump, xoojinta, ka-hortagga-yaraynta iyo ilaalinta deegaanka.Waxay si buuxda u xallin kartaa daciifnimada xoogga sare, la taaban karo ee waxqabadka sare leh oo leh waxqabadka sare ee viscosity iyo waxqabadka dhismaha oo liita.
Faa'iidada in lagu dabaqo isku-dhafka la taaban karo waa sida soo socota:
1) Xoog hore oo aad u korodhay
2) Hoos u dhac weyn oo lumay
3) adkeysi heer sare ah: Yaraynta dildilaaca, yaraanshaha iyo gurguurta
4) Biyo-yaraynta sare: Biyo dhimista in ka badan 30% marka loo eego codsiyada kala duwan
5) Alaabooyinka deegaanka u saaxiibka ah: Wax wasakh ah ma leh inta lagu jiro wax soo saarka
6) Waafaqid aad u wanaagsan oo leh noocyada kala duwan ee sibidhka
7) Koloriin hoose iyo alkali, oo aan daxalka lahayn birta-baarka
Waa kuwee PCE-yada aan hadda u bixinayno suuqa gudaha iyo dibadda?
PCE 50% Haysashada Sarreysa ee Slum
PCE 50% Yaraynta Biyaha Sare
PCE 50% Xoogga Hore ee Sare
PCE budada
Waa maxay qiyaasta PCE?
Qiyaasta ugu wanaagsan ee PCE-ga si loo buuxiyo shuruudaha gaarka ah waa in had iyo jeer lagu go'aamiyaa tijaabooyinka iyadoo la adeegsanayo agabka iyo xaaladaha loo isticmaali doono.
Sannado badan, Qalabka Dhismaha Chengli wuxuu had iyo jeer u hoggaansamaa tayada aasaaska, hal-abuurka awoodda, oo ku dadaal inaad noqoto hoggaamiyaha warshadaha wax-ku-darka la taaban karo.Haddii aad raadinayso qalab dhisme, fadlan xor u noqo inaad nala soo xidhiidho wakhti kasta.Waxaan sugeynaa weydiintaada, waxaana rajeyneynaa inaan adiga kula sameyno wadashaqeyn waqti dheer oo xasilloon.
