Umgubo wePolymer ophinda unyibilike (RDP)
I-CAS: 24937-78-8
Umgubo wePolymer ophinda unyibilike(RDP) yi-spray dry emulsion redispersible latex powder, eyenzelwe ishishini lokwakha ukuphucula iipropati ze-dry mortar mixes, ekwaziyo ukudispersible emanzini kwaye isabela kwi-hydrate product yesamente/gypsum kunye ne-stuffing, yenze i-composite membrane enobunkunkqele obuhle.
Iphucula iipropati ezibalulekileyo zokusetyenziswa kweemortar ezomileyo, njengokuhlala ixesha elide zivuliwe, ukunamathela ngcono kwiisubstrates ezinzima, ukusetyenziswa kwamanzi okuncinci, ukukrazuka okungcono kunye nokumelana nempembelelo.
Emva kokomiswa ngesitshizi, i-VAE emulsion iguqulwa ibe ngumgubo omhlophe oyi-copolymer ye-ethyl kunye ne-vinyl acetate. Ihamba ngokukhululekileyo kwaye kulula ukuyixuba. Xa isasazwa emanzini, yenza i-emulsion ezinzileyo. Ineempawu eziqhelekileyo ze-VAE emulsion, le powder ihamba ngokukhululekileyo inika lula ukuphathwa kunye nokugcinwa. Ingasetyenziswa ngokuxuba nezinye izinto ezifana nomgubo, ezifana nesamente, isanti kunye nezinye izinto ezilula, kwaye ingasetyenziswa njengesihlanganisi kwizixhobo zokwakha kunye nezincamathelisi.
I-Redispersible Polymer Powder (RDP) inyibilika emanzini ngokulula kwaye yenza i-emulsion ngokukhawuleza. Iphucula iipropati ezibalulekileyo zokusetyenziswa kweemortar ezomileyo, ixesha elide lokuvula, ukunamathela okungcono kwi-substrates ezinzima, ukusetyenziswa kwamanzi okuncinci, ukukrazuka okungcono kunye nokumelana nempembelelo.
I-colloid ekhuselayo: I-Polyvinyl alcohol
Izongezo: Iiarhente ezichasene neebhloko zeminerali

IsitshixoIipropati:
I-Redispersible Polymer Powder RDP inokuphucula ukunamathela, amandla okugoba, ukumelana nokukrweleka, ukuguquguquka. Ine-rheology elungileyo kunye nokugcinwa kwamanzi, kwaye inokunyusa ukumelana nokugqwala kwee-adhesive zethayile, inokwenza ii-adhesive zethayile ezineempawu ezintle zokungagungqi kunye ne-putty ezineempawu ezilungileyo.
Imiboniso eyodwa:
I-Redispersible Polymer Powder RDP ayinampembelelo kwi-rheological preperties kwaye ayikhuphi ukukhutshwa komoya okuphantsi,
Umgubo oqhelekileyo osetyenziswa ngokubanzi kuluhlu oluphakathi lwe-Tg. Ufanelekile kakhulu
ukwenza iikhompawundi ezinamandla aphezulu.
