Yintoni iRedispersible Polymer Powder (RDP)?

I-Redispersible Polymer Powder yi-polymer powder ejikelezayo, eyomileyo, eyomileyo efunyenwe kwi-emulsions ye-polymer. Ezi powders ziphinde zisasazeke emanzini ukuze zenze kwakhona i-emulsion ye-polymer, inika iipropati eziphuculweyo kumxube wodaka.

Ukuqulunqwa kwe-RDP

Ii-RPPs ikakhulu ziquka:

1. Isiseko sePolymer:I-Vinyl acetate ethylene (VAE), i-styrene-butadiene (SB), okanye i-acrylic-based polymers.
2. IiColloids ezikhuselayo:I-Polyvinyl alcohol (PVA) okanye ezinye izizinzi zithintela ukudibanisa kwangaphambi kwexesha.
3. Iiarhente ezichasene neCaking:Izigcwalisi zamaminerali ezifana ne-silica okanye i-calcium carbonate ziphucula ukuhamba kunye nokuzinza kokugcina.
4. Izongezo:Ukuphucula i-hydrophobicity, ukuguquguquka, okanye ixesha lokumisela.

Ukusebenza kwe-RDP kwi-Drymix Mortar

Ukufakwa kwe-RDP kwi-drymix mortar formulations ibonelela ngeenzuzo ezininzi:

1. Ukunamathela okomeleziweyo:I-RDP yonyusa amandla ebhondi phakathi kodaka kunye neesubstrates ezifana nekhonkrithi, izitena, iithayile, kunye neebhodi zokugquma.
2. Uphuculo loGuquko kunye noKuchasa uTshintsho:Kubalulekile kwizicelo ezifuna ukumelana nokuqhekeka kunye nokuguquguquka, njengeenkqubo zangaphandle ze-thermal insulation composite systems (ETICS).
3. Ugcino lwamanzi kunye nokuSebenza:Uqinisekisa ukuhanjiswa kwamanzi ngendlela eyiyo kwesamente, ukunciphisa ilahleko yamanzi kunye nokwandisa ixesha elivulekileyo lokufaka isicelo.
4. Amandla oomatshini kunye nokuqina:Yomeleza umanyano, ukuxhathisa kwe-abrasion, kunye nokuchasana kwempembelelo, ukuqinisekisa ukuthembeka kwesakhiwo sexesha elide.
5. Ukumelana naManzi kunye ne-Hydrophobicity:Ii-RDP ezikhethekileyo zinokunikezela ngeempawu zokugxotha amanzi, eziluncedo kwizicelo zokuthintela amanzi.
6. Ukuxhathisa i-Freeze-Thaw:Inceda ukugcina ukusebenza kwiimeko zemozulu ezahlukeneyo.
7. Ukuphuculwa kweRheology kunye neePropati zeSicelo:Ukwandisa ukuhamba kunye nokulula kokusetyenziswa kuzo zombini izicelo zemanuwali kunye noomatshini.

Iindidi zeRDP eziSekwe kwiPolymer Composition

1. IVinyl Acetate-Ethylene (VAE):
   • Isetyenziswa ngokuqhelekileyo kwizinto zokuncamathelisa iithayile, udaka lokutyabeka, kunye neekhompawundi zokuzilinganisa.
   • Inika ukuguquguquka okulinganayo kunye nokubambelela.
2. I-Styrene-Butadiene (SB):
   • Inikeza ukuxhathisa kwamanzi aphezulu kunye nokuguquguquka.
   • Ifaneleka kwimibhobho yokukhusela amanzi kunye nokulungiswa kweendonga.
3. I-Acrylic-based RPP:
   • Amandla aphezulu okubambelela kunye nokuchasana kwe-UV.
   • Ekhethwayo kwiingubo zokuhombisa kunye nezicelo zokukhusela amanzi.

Izicelo ze-RDP kwi-Drymix Mortar

1. Izinto zokuncamathelisa iithayile kunye neGrout yeThayile:Ukwandisa ukunamathela kunye nokuguquguquka kokubambisana okungcono phakathi kweethayile kunye ne-substrates.
2. IiPlasta kunye neziBonelelo:Ukuphucula ukubambisana, ukusebenza, kunye nokumelana nokuqhekeka.
3. IiCompounds zokuZilinganisa (SLCs):Ibonelela ngomgangatho ogudileyo kunye nokuhamba kakuhle kunye nokomelela.
4. I-ETICS (IiNkqubo zaNgaphandle zokugquma i-Thermal Insulation Composite):Igalelo kwimpembelelo yokuchasa kunye nokuguquguquka.
5. Iintsimbi zokuvala amanzi:Ukuphucula iimpawu ze-hydrophobic, ukuqinisekisa ukukhuselwa ekungeneni komswakama.
6. Lungisa udaka:Ukuphucula ukubambelela, amandla omatshini, kunye nokuqina kwezicelo zokulungisa ikhonkrithi.
7. Udaka lweMasonry:Ukwandisa ukusebenza kunye namandla okudibanisa kwizicelo zokubeka izitena.
