Redispersible looj cov hmoov thiab cov cement yog cov khoom sib raug zoo thiab ua yeeb yaj kiab ua yeeb yaj kiab ntawm cov dej-resistant putty. Lub hauv paus-resistant txoj ntsiab cai yog:
Thaum lub sij hawm sib xyaw ua ke ntawm recispersible loojas tau rov qab mus rau thawj qhov emulsion tau muab cov khoom siv looj ua ke rau hauv cov xis mas slurry. Tom qab cov cement ntsib dej, cov hydration kev tiv thaiv pib, CA (Frystals, thiab hydrated calcium silate colium yog muab tso rau ntawm gel thiab tsis muaj zog. ntawm Maas hais.
Nrog rau kev nce qib ntawm cov tshuaj tsw qab, cov khoom sib sau ua ke ntxiv rau hauv cov khoom siv hauv cov khoom siv inorganic xws li cov cement, thiab ua kom nruj pob txheej rau saum npoo ntawm cov cement gel. Vim tias maj mam txo ntawm cov dej noo qhuav, cov redispersed looj cov lus sib xyaw kom sib xyaw kom sib xyaw ua ke, thiab ua cov pob txha ua kom tawv nqaij thiab lwm yam hmoov av nplaum. Vim hais tias cov pa roj looj kev coaguling thiab tsim ib zaj duab xis hauv qhov chaw hloov pauv ntawm Caas thiab lwm qhov kev hloov pauv ntawm lub cev nqaij daim tawv, yog li txhim kho nws cov dej tsis kam.
Nyob rau tib lub sijhawm, cov pab pawg nquag tsim los ntawm Redispersible looj cov quav me me, muaj cov roj teeb uas muaj zog, xws li cov khoom siv roj teeb , ua tus qauv tshwj xeeb choj, txhim kho lub cev cov qauv ntawm cov xis ntshiab hardened lub cev, thiab txhim kho lub compactness ntawm lub putty interface. Tus redispersed looj cov lus sau ib qho txuas ntxiv thiab ntom zaj duab xis nyob rau hauv voids ntawm lub cev putty.
