Ịkwalite hydrophobicity na ibelata mmịpụta mmiri

Ịtinye ntụ ntụ latex na-agbanwe agbanwe nwere ike melite microstructure nke ngwa ngwa ciment. Polymer ya na-etolite netwọk a na-apụghị ịgbagha agbagha na usoro hydration ciment, na-emechi capillary na gel ciment, na-egbochi ntinye mmiri, ma na-eme ka ọ dịkwuo mma.

Melite ike njikọta na njikọta

Uzuzu latex na-agbanwe agbanwe nwere mmetụta dị ukwuu n'ịkwalite ike njikọ na njikọta nke ihe. N'ihi ntinye nke mkpụrụ ndụ polymer n'ime pores na capillaries nke cement matrix, ọ na-eme ka njikọ dị mma mgbe hydration na ciment gasịrị. The magburu onwe adhesion nke polymer resin n'onwe ya mma adhesion nke ciment ngwa agha ngwaahịa na substrates, karịsịa na-adịghị mma adhesion nke inorganic binders dị ka ciment na organic substrates dị ka osisi, eriri, PVC, na EPS, mmetụta doro anya.
