Polycarboxylic acid high efficiency dej txo tus neeg sawv cev kuaj cov khoom
Dab tsi yog polycarboxylic acid kev ua haujlwm siab ua haujlwm dej txo cov neeg ua haujlwm: cov dej txo cov neeg ua haujlwm yog cov dej txo cov neeg ua haujlwm raws li cov polymers ua los ntawm carboxyunsaturated monomers thiab lwm yam monomers.
Kev faib tawm ntawm polycarboxylic acid high-efficiency dej txo tus neeg sawv cev yog muab faib ua hom qauv (code S), hom thaum ntxov muaj zog (code A), qeeb hom (code R), hom kev tso tawm (code SR), hom shrinkage (code RS ), antifreeze hom (code AF ).
Raws li cov khoom lag luam ntawm cov dej txo tus neeg sawv cev, nws muab faib ua kua (code L) thiab hmoov (code P).
Cov khoom kuaj pom rau qhov sib xws ntawm polycarboxylic acid cov dej ua haujlwm siab txo tus neeg sawv cev suav nrog cov ntsiab lus formaldehyde Tsawg dua lossis sib npaug li 300mg / kg, chloride ion ntsiab lus tsawg dua lossis sib npaug li 0.1%, cov ntsiab lus khoom, cov ntsiab lus noo noo thiab Qhov ceev yuav tsum ua raws li cov kev cai ntawm GB 8076, thiab tag nrho cov alkali tus nqi, fineness thiab pH tus nqi yuav tsum nyob rau hauv kev tswj ntawm cov nroj tsuag ntau lawm.
Cov khoom kuaj xyuas lub Hoobkas suav nrog cov ntsiab lus formaldehyde, cov ntsiab lus chloride ion, tag nrho cov ntsiab lus alkali, cov ntsiab lus ruaj khov, cov ntsiab lus noo noo, ntom, zoo, pH tus nqi. Ntawm lawv, cov ntsiab lus chloride ion raug kuaj tsawg kawg ib zaug txhua 3 lub hlis, thiab tag nrho cov ntsiab lus alkali raug kuaj tsawg kawg ib xyoos ib zaug.
Cov kev cai coj mus kuaj: 1. Kev kuaj yuav tsum tau ua raws li cov kev cai ntawm GB 8076; 2. Tus nqi piv txwv ntawm txhua batch tsis tsawg tshaj li 0.2t ntawm cov cement xav tau polycarboxylic acid high-performance dej txo koob tshuaj; 3. Cov qauv tau txais hauv txhua pawg yuav tsum tau muab sib xyaw ua ke thiab muab faib ua ob qhov sib npaug.
Ib qho ntawm lawv raug kuaj raws li cov txheej txheem thiab cov khoom tau teev tseg hauv tus qauv JG/T 223-2017, thiab lwm daim ntawv luam raug kaw thiab khaws cia rau 6 lub hlis rau kev rov tshuaj xyuas lossis kev txiav txim plaub ntug.
