Mhedzisiro yekuwedzera Redispersible polymer poda kune putty poda

Redispersible latex poda inoshandiswa mune imwe-chikamu JS isina mvura yekuputira, polystyrene board bonding dhaka rekuvaka insulation, inochinjika pamusoro pekudzivirira dhaka, polystyrene particle thermal insulation coating, tile adhesive, self-leveling dhaka, yakaoma-yakasanganiswa dhaka, putty, nezvimwe. munda wekugadzirisa inorganic gelling zvinhu zvakashandiswa zvakanyanya.

 

Kuwedzera redispersible latex poda kune putty poda inogona kuwedzera simba rayo, kuve nekunamira kwakasimba uye michina zvinhu, uye kubatsira kuvandudza kuomarara. Iyo ine yakanaka yekudzivirira mvura, permeability, uye yakanakisa kusimba. Alkaline, inodzivirira kupfeka, uye inogona kuvandudza kuchengetwa kwemvura, kuwedzera nguva yakavhurika, uye kuwedzera kusimba.

 

Kana iyo redispersible latex poda inomutswa zvakaenzana muputty poda uye yakasanganiswa nemvura, inoparadzirwa muzvikamu zvakanaka zvepolymer; simende gel inoumbwa zvishoma nezvishoma kuburikidza nekutanga hydration ye simenti, uye chikamu chemvura chinoumbwa neCa (OH) 2 mu hydration process. Yakazara, nepo latex poda inoumba polymer particles uye inoisa pamusoro peiyo simenti gel / unhydrated simende particle musanganiswa; sezvo simiti inowedzera hydrated, mvura iri mu capillaries inoderera, uye zvikamu zvepolymer zvishoma nezvishoma zvinorambidzwa mu capillaries. Adhesive/unhydrated sement particle musanganiswa uye filler surface inoumba dhiri rakavharika; pasi pechiito che hydration reaction, base layer absorption uye evaporation yepasi, mvura inowedzera kuderedzwa, uye iyo yakaumbwa yakaturikidzana layer inoungana kuita firimu, inosunga iyo hydration reaction chigadzirwa muPamwechete vanogadzira yakazara network chimiro. Iyo composite sisitimu inoumbwa nesamende hydration uye latex poda firimu kuumbwa inogona kuvandudza yakasimba yekupwanya kuramba kweputty kuburikidza nekuita kwekubatana.

 

Iyo putty inoshandiswa sechinhanho chekuchinja pakati pekunze kwemadziro ekudzivirira uye pendi haifanirwe kusimba kupfuura kupurasita dhaka, zvikasadaro kuputika kunoitika nyore. Mune iyo yese insulation system, kuchinjika kweiyo putty kunofanirwa kunge kwakakwira kupfuura iyo yekutanga zvinhu. Nenzira iyi, iyo putty inogona kuchinjika zvirinani kune deformation ye substrate uye kuvharira iyo yega deformation pasi pechiito chekunze kwemamiriro ekunze, kudzoreredza kushushikana, uye kuderedza mukana wekuputika uye kupeuka kwejasi.
