Ndeipi basa redhispersible latex poda mugypsum-based self-leveling?

Redispersible latex powder chinhu chakakosha chekuwedzera chinokanganisa kushanda kwegobvu-layer gypsum-based self-leveling mortar. Kupesvedzera kwe-re-dispersible latex powder pane zvemuviri uye zvemagetsi zvimiro zvegobvu-layer gypsum-based self-leveling mortar inoedzwa, uye iyo redispersible latex poda inoratidzwa kuburikidza nekuongorora diki. Iyo musimboti wekuvandudza ma mechanic properties yegypsum-based self-leveling mortar inoratidza kuti redispersible latex poda inoita basa guru mugypsum-based self-leveling.

Redispersible latex poda inoshandiswa zvakanyanya organic binder, iyo inogona kuvandudza mashandiro ezvigadzirwa kana ichishandiswa mune gypsum-based kuvaka zvinhu. Ongororo dzakaona kuti kuyerera kwekutanga kwegobvu-layer gypsum-based self-leveling mortar inowedzera kutanga uye inoderera nekuwedzera kwehuwandu hwe latex powder. Chikonzero ndechekuti latex powder ine imwe viscosity mumvura yakanyungudutswa. Kukwanisa kumiswa kwe slurry kune filler inovandudzwa, iyo inobatsira pakuyerera kwe slurry; apo huwandu hwe latex powder hunoramba huchiwedzera, kuwedzera kwe viscosity ye slurry kunotungamirira kukuwedzera kwehutachiwana hwe slurry, uye fluidity inoratidza kuderera. Huwandu hwe latex powder hunenge husina mhedzisiro pa 20min fluidity yedhaka.

Sezvo organic binder, simba re latex powder rinoenderana nekubuda kwemvura mu slurry, uye simba rezvisungo rinoumbwa nekugadzirwa kwefirimu. Munyika yakaoma, mvura iri mugypsum-based self-leveling mortar inoputika, uye latex powder inogona kuumba firimu rinopfuurira. Zvirinani kunamatira, iyo yakaoma simba yegypsum-based self-leveling mortar inowedzera nekuwedzera kwehuwandu hwe latex powder.

Mune gypsum-based self-leveling mortar isina latex poda, kune nhamba huru yetsvimbo-yakaita uye columnar dihydrate gypsum crystals uye irregular filler dihydrate gypsum crystals uye pakati pe dihydrate gypsum crystals uye fillers. Muunganidze pamwe chete kuti gypsum-based self-leveling dhaka ibudise simba, uye gypsum-based self-leveling dhaka yakasanganiswa ne redispersible latex poda, iyo latex poda inoumba filamentary yekubatanidza mudhaka regypsum-based self-leveling, uye dihydrate. gypsum makristasi uye mafirita, makristasi Bhiriji regirosi rinoumbwa pakati pekristaro uye dihydrate gypsum crystal, uye organic firimu inoumbwa pane dihydrate gypsum crystal kuputira uye kubatanidza zvikamu zvinopindirana pakati peiyo dihydrate gypsum makristasi, nekudaro ichiwedzera kubatana uye kubatana. yegypsum-based self-leveling mortar uye kuvandudza simba regypsum-based self-leveling mortar Iyo latex powder ine firimu-inogadzira zvinhu mumatope, iyo inogona kuvandudza kuwirirana uye kusungirirwa kwesimba revhu rakaoma. Kuumbwa kwekubatana kunoshanda pakati pemafiritsi kunonatsiridza kubatana pakati pe dihydrate gypsum crystals uye mafirita, nekudaro kuvandudza kusimba kwechisungo chegypsum-based self-leveling mortar macroscopically.
