I-Redispersible Polymer Powder (RDP) i-polymer esetyenziswa kwiintlobo ezahlukeneyo zezicelo. I-RDP ngumgubo onyibilikayo wamanzi owenziwe kwiipolymers ezahlukeneyo, kubandakanya i-vinyl acetate, i-vinyl acetate ethylene, kunye ne-acrylic resins. I-powder ixutywe namanzi kunye nezinye izongezo zokwenza i-slurry, ethi isetyenziswe kwii-substrates ezahlukeneyo. Kukho iindidi ezininzi ze-RDP, nganye ineempawu zayo ezizodwa kunye nokusetyenziswa kwayo. Kweli nqaku, siza kuphonononga ezinye zezona ntlobo zixhaphakileyo ze-RDP kunye nezicelo zazo.
1. I-Vinyl acetate i-polymer ephinda ihlakazwe
IVinyl acetate redispersible polymers lolona hlobo luqhelekileyo lweRDP. Zenziwe kwi-vinyl acetate kunye ne-vinyl acetate ethylene copolymer. Iinqununu ze-polymer zihlakazwa emanzini kwaye zinokuphinda zibuyiswe kwimeko yolwelo. Olu hlobo lwe-RDP lunoluhlu olubanzi lwezicelo ezibandakanya udaka lomxube owomileyo, iimveliso zesamente kunye neekhompawundi zokuzilinganisa. Banikezela ngokubambelela kakuhle, ukuguquguquka kunye nokuqina.
2. I-Acrylic redispersible polymer
I-Acrylic redispersible polymers zenziwe nge-acrylic okanye i-methacrylic copolymers. Amandla abo angaqhelekanga kunye nokuxhathisa ukukrazuka kubenza balungele usetyenziso apho ukuqina kubaluleke kakhulu. Zisetyenziselwa ukunamathela kwi-tile, i-insulation yangaphandle kunye neenkqubo zokugqiba (EIFS), kunye nokulungiswa kodaka.
3. I-ethylene-vinyl acetate i-polymer ephinda iphinde iphindwe
I-ethylene-vinyl acetate redispersible polymers zenziwe kwi-ethylene-vinyl acetate copolymers. Zisetyenziswa kwizicelo ezahlukeneyo ezibandakanya udaka lwesamente, iigrouts kunye nokunamathelisa iithayile. Banokuguquguquka okugqwesileyo kunye nokunamathela ukuze basetyenziswe kwiindawo zoxinzelelo oluphezulu.
4. I-Styrene-butadiene i-polymer ehlaziywayo
I-Styrene-butadiene iipolymers ezihlaziywayo zenziwe kwi-styrene-butadiene copolymers. Zisetyenziswa kwiintlobo ezahlukeneyo zezicelo ezibandakanya udaka lokulungiswa kwekhonkrithi, i-adhesives tile kunye ne-grouts. Banokumelana okugqwesileyo kwamanzi kunye neempawu zokubambelela.
5. Umgubo wepolymer owenziwe ngokutsha
I-polymer e-emulsifiable powder powder yi-RDP eyenzelwe ukuphinda ifakwe emanzini emva kokumisa. Isetyenziswe kwizicelo ezininzi apho imveliso ibonakaliswe kumanzi okanye umswakama emva kokusetyenziswa. Ezi zibandakanya ukunamathiswa kweethayile, i-grout, kunye ne-caulk. Banokumelana okugqwesileyo kwamanzi kunye nokuguquguquka.
6. Hydrophobic redispersible polymer powder
I-Hydrophobic redispersible polymer powders eyenzelwe ukunyusa ukuxhathisa kwamanzi kwiimveliso ezisekelwe kwisamente. Ngokuqhelekileyo isetyenziswa kwizicelo apho imveliso iya kudibana namanzi, njenge-Exterior Insulation and Finishing Systems (EIFS), i-adhesive pool tile adhesives kunye ne-concrete yokulungisa i-concrete. Inokumelana okugqwesileyo kwamanzi kunye nokuqina.
I-latex powder ye-redispersible yinto eguquguqukayo enokusetyenziswa kwizicelo ezininzi. Kukho iindidi ezininzi ze-RDP, nganye ineempawu zayo ezizodwa kunye nokusetyenziswa kwayo. Ukunamathela kwabo okugqwesileyo, ukuguquguquka kunye nokuqina kubenza balungele ukusetyenziswa kwiimveliso ezahlukeneyo. Xa zisetyenziswe ngokuchanekileyo, zinokunceda ukuphucula umgangatho kunye nobude bezinto ezininzi zokwakha.
