FC-R20L Polymer high-temperature retarder
Retarder pab txuas ntxiv lub sijhawm thickening ntawm cov cement slurry txhawm rau ua kom nws nqus tau, uas, yog li ntawd, ua kom lub sijhawm nqus dej txaus rau kev nyab xeeb cementing project.
• FC-R20L yog ib hom organic phosphonic acid nruab nrab-tsawg kub retarder.
• FC-R20L tuaj yeem txuas ntxiv lub sijhawm thickening ntawm cov cement slurry, muaj zog tsis tu ncua, thiab tsis muaj kev cuam tshuam rau lwm yam khoom ntawm cov cement slurry.
• FC-R20L muaj feem xyuam rau kev npaj slurry ntawm cov dej tshiab, dej ntsev thiab dej hiav txwv.

Concrete retarders yog cov sib tov uas ua rau qeeb cov txheej txheem tshuaj hydration kom cov pob zeb tseem tshuav yas thiab ua haujlwm tau ntev, cov retarders yog siv los kov yeej cov nyhuv nrawm ntawm qhov kub thiab txias ntawm kev tsim cov khoom ntawm pob zeb hauv cov huab cua kub.Retarder tuaj yeem ua kom ntev lub sijhawm thickening ntawm cov cement slurry thiaj li ua kom muaj kev ua haujlwm zoo cementing.Foring chemicals muaj FC-R20L, FC-R30S thiab FC-R31S series los siv rau hauv ntau daim ntawv thov.
Q1 Koj cov khoom tseem ceeb yog dab tsi?
Peb tsuas yog tsim cov roj zoo cementing thiab drilling additives, xws li kev tswj tsis tau dej, retarder, dispersant, anti-gas migration, deformer, spacer, flushing kua thiab lwm yam.
Q2 Koj puas tuaj yeem muab cov qauv?
Yog lawm, peb tuaj yeem muab cov qauv dawb.
Q3 Koj puas tuaj yeem kho cov khoom?
Yog lawm, peb tuaj yeem muab koj cov khoom raws li koj qhov yuav tsum tau ua.
Q4 Lub teb chaws twg yog koj cov neeg siv khoom tseem ceeb los ntawm?
North America, Asia, Europe thiab lwm thaj chaw.
