Yintoni iRedispersible Polymer Powders?

I-polymer powder ye-redispersible (RDP) luhlobo lwepolymer powder olunokuthi luphinde luhlakazwe emanzini ukuze zenze i-dispersion ezinzileyo okanye i-emulsion.Ingumgubo owomileyo oveliswa ngokutshiza-yomisa i-emulsion ye-polymer.I-RDP isetyenziswa kwiintlobo ngeentlobo zezicelo, kubandakanywa ulwakhiwo, izinto zokuncamathelisa, izinto zokwaleka kunye nezitywini.

I-RDP yenziwe ngeendidi zepolymers, ezifana ne-acrylics, i-polyvinyl acetate (PVA), i-polyvinyl alcohol (PVOH), kunye ne-styrene-butadiene (SBR).Iipolymers ziqhele ukudityaniswa kunye ukwenza umgubo oneempawu ezinqwenelekayo.Umgubo ke uyatshizwa ukuze wenze umgubo owomileyo.Umgubo unokuphinda usasazwe emanzini ukwenza i-dispersion ezinzileyo okanye i-emulsion.

I-RDP isetyenziswa kwiintlobo ngeentlobo zezicelo, kubandakanywa ulwakhiwo, izinto zokuncamathelisa, izinto zokwaleka kunye nezitywini.Kulwakhiwo, i-RDP isetyenziswa njengesongezo kwiidaka ezenziwe ngesamente kunye neeplasta.Iphucula ukusebenza, ukunamathela, kunye nokumelana namanzi kodaka okanye udaka.Kwii-adhesives, i-RDP isetyenziselwa ukuphucula ukudibanisa kwe-adhesive kwi-substrate.Kwiingubo, i-RDP isetyenziselwa ukuphucula ukunyanzeliswa kwamanzi kunye nokuguquguquka kwengubo.Kwii-sealants, i-RDP isetyenziselwa ukuphucula ukubambelela kunye nokuguquguquka kwe-sealant.

I-RDP ikwasetyenziswa kwiintlobo ngeentlobo zezinye izinto ezisetyenziswayo, ezinje ngephepha lokutyabeka, iingubo zesikhumba, kunye neengubo ezilaphu.Kwiingubo zephepha, i-RDP isetyenziselwa ukuphucula ukunganyangeki kwamanzi kunye namandla ephepha.Kwiingubo zesikhumba, i-RDP isetyenziselwa ukuphucula ukunganyangeki kwamanzi kunye nokuguquguquka kwesikhumba.Kwiingubo zokugqoka, i-RDP isetyenziselwa ukuphucula ukunyanzeliswa kwamanzi kunye nokuguquguquka kwelaphu.

I-RDP yimathiriyeli eguquguqukayo esetyenziswa kwiintlobo ngeentlobo zezicelo.Ingumgubo owomileyo onokuphinda uhlakazwe emanzini ukuze wenze ukusabalalisa okuzinzile okanye i-emulsion.I-RDP isetyenziselwa ulwakhiwo, izinto zokuncamathelisa, iingubo kunye nezitywini ukuphucula ukusebenza, ukuncamathela, kunye nokunganyangeki kwamanzi kwimveliso.I-RDP ikwasetyenziswa kwiintlobo ngeentlobo zezinye izinto ezisetyenziswayo, ezinje ngeengubo zephepha, iingubo zesikhumba, kunye neengubo ezilaphu.
