Ziziphi iipolymer powders ezinokuphinda zihlakazwe?

I-polymer powders i-redispersible (RPP) i-free-flowing, i-powders emhlophe eveliswa yi-spray-drying polymer dispersions okanye i-emulsions. Ziquka iinqununu ze-polymer ezifakwe kwii-agent zokukhusela kunye nezongezo. Xa ixutywe namanzi, ezi powders zisasazeka ngokukhawuleza ukuze zenze i-emulsions ye-polymer ezinzile, eyenza ukuba ukusetyenziswa kwazo kuluhlu olubanzi lwezicelo zokwakha, iipeyinti kunye neengubo, i-adhesives, kunye namanye amashishini.

Ukuqulunqwa:

Ukwakhiwa kwepolymer powders enokuphinda ihlakazwe ngokuqhelekileyo kubandakanya ezi nxalenye zilandelayo:

  1. I-Polymer Particles: Inxalenye ephambili ye-RPP yi-polymer particles, ephuma kwiipolymers ezahlukeneyo zokwenziwa ezifana ne-vinyl acetate-ethylene (VAE), i-ethylene-vinyl acetate (EVA), i-acrylics, i-styrene-butadiene (SB), okanye i-polyvinyl acetate ( PVA). Ezi polymers zinegalelo kwiipropati ezifunwayo kunye neempawu zokusebenza zemveliso yokugqibela.
  2. Ii-Agents ezikhuselayo: Ukukhusela iinqununu ze-polymer kwi-agglomerating ngexesha lokugcina kunye nokuthutha, ii-agent zokukhusela ezifana ne-polyvinyl alcohol (PVA) okanye i-cellulose ethers zihlala zisetyenziswa. Ezi arhente zizinzisa iinqununu ze-polymer kwaye ziqinisekise ukuphinda ziphinde ziphinde ziphinde ziphinde ziphinde ziphinde zenziwe emanzini.
  3. Iiplastiki: Iiplastiki zingongezwa ukuphucula ukuguquguquka, ukusebenza, kunye nokunamathela kwe-RPPs. Ezi zongezo zinceda ukwandisa ukusebenza kwamasuntswana e-polymer kwizicelo ezahlukeneyo, ngakumbi kwiingubo eziguquguqukayo, i-adhesives, kunye ne-sealants.
  4. Izigcwalisi kunye nezongezelelo: Ngokuxhomekeke kwiimfuno ezithile zesicelo, iifayili, ii-pigments, i-agent e-crosslinking, i-thickeners, kunye nezinye izongezo zingabandakanywa kwiifom ze-RPP zokuphucula iipropati zabo okanye ukubonelela ngemisebenzi ethile.

Iinkcazelo ngeempawu kunye neempawu:

Iipolymer powders ezinokuphinda ziphinde zisetyenziswe zibonisa iipropathi ezininzi eziphambili kunye neempawu ezizenza zisebenziseke kwaye zisetyenziswe ngokubanzi kumashishini ahlukeneyo:

  1. I-Redispersibility: I-RPP isasazeka ngokukhawuleza emanzini ukuze yenze i-emulsions ye-polymer ezinzile okanye i-dispersions, ivumela ukufakwa lula kwiifom kunye nesicelo esilandelayo.
  2. Amandla okwenza iFilimu: Xa ihlakazwe emanzini kwaye isetyenziswe kwiindawo eziphezulu, i-RPP inokwenza iifilimu ezincinci, eziqhubekayo xa zomiswa. Ezi filimu zongeza ukuncamathelisa, ukuqina, kunye nokumelana nemozulu kwiingubo, izinto zokuncamathelisa, kunye nezitywini.
  3. I-Adhesion ephuculweyo: I-RPP iphucula ukubambelela phakathi kwe-substrates kunye neengubo, ii-mortars, okanye i-adhesives, okubangelwa izibophelelo ezinamandla kunye nokusebenza okuphuculweyo kulwakhiwo kunye nezinto zokwakha.
  4. Ukugcinwa kwamanzi: Ubume be-hydrophilic be-RPP bubenza bakwazi ukufunxa kunye nokugcina amanzi ngaphakathi kwe-formulation, ukwandisa i-hydration kunye nokuphucula ukusebenza, ixesha elivulekileyo, kunye nokubambelela kwi-mortar kunye ne-adhesive applications.
  5. Ukuguquguquka kunye nokuqina: Izinto eziguquliweyo ze-RPP zibonisa ukuguquguquka okwandisiweyo, ukuqina, kunye nokuqina, okwenza ukuba zixhathise ngakumbi ukuqhekeka, ukuguqulwa, kunye nomonakalo wempembelelo.
  6. Ukumelana neMozulu: Ii-RPPs zonyusa ukuxhathisa kwemozulu kunye nokuqina kweengubo, izitywini, kunye neembrane zokuthintela amanzi, zibonelela ngokhuseleko oluhlala ixesha elide kwimitha ye-UV, ukufuma kunye nezinto zokusingqongileyo.

Usetyenziso:

Iipolymer powders eziphinda zihlakazwe zifumana izicelo kuluhlu olubanzi lwamashishini kunye neemveliso, kubandakanya:

  • Ulwakhiwo: Izinto zokuncamathelisa iithayile, udaka, iigrouts, iimbrane zokuthintela amanzi, iikhompawundi ezizilinganisayo, kunye neenkqubo zangaphandle zokugquma nokugqiba (EIFS).
  • Iipeyinti kunye neeNgqungquthela: Ipeyinti yangaphandle, iipeyinti ezenziwe ngombala, iiplaster zokuhombisa, kunye neengubo zokwakha.
  • I-Adhesives kunye ne-Sealants: I-adhesives ye-tile, i-crack fillers, i-caulks, i-flexible sealants, kunye ne-adhesive-sensitive adhesives.
  • Iimpahla: Iingubo zokwaleka, ii-ejenti zokugqiba, kunye neekhompawundi zokulinganisa.

i-polymer powders enokuphinda iphindwe kwakhona inezinto ezininzi kunye nemisebenzi emininzi esetyenziselwa ukuphucula ukusebenza, ukuqina, kunye nokuguquguquka kweemveliso ezahlukeneyo kunye nokwakheka kulwakhiwo, iipeyinti kunye neengubo, izinto zokuncamathelisa, iingubo, kunye namanye amashishini.
