I-Redispersible Polymer Powder (RDP) yi-polymer esetyenziswa kwiintlobo ngeentlobo zezicelo. I-RDP yi-powder enyibilikayo emanzini eyenziwe ngee-polymers ezahlukeneyo, kubandakanya i-vinyl acetate, i-vinyl acetate ethylene, kunye ne-acrylic resins. I-powder ixutywa namanzi kunye nezinye izongezo ukuze zenze i-slurry, ethi emva koko isetyenziswe kwii-substrates ezahlukeneyo. Kukho iintlobo ezahlukeneyo ze-RDP, nganye ineempawu zayo ezizodwa kunye nokusetyenziswa kwayo. Kweli nqaku, siza kuhlola ezinye zezona ntlobo zixhaphakileyo ze-RDP kunye nokusetyenziswa kwazo.
1. I-vinyl acetate i-polymer ephinda inyibilike
Iipolymers ze-vinyl acetate eziphinda zichithwe zezona ntlobo zixhaphakileyo ze-RDP. Zenziwe nge-vinyl acetate kunye ne-vinyl acetate ethylene copolymer. Amasuntswana e-polymer asasazwa emanzini kwaye anokuphinda ahlanganiswe abe yimeko yolwelo. Olu hlobo lwe-RDP luneendlela ezahlukeneyo zokusetyenziswa kuquka iimortars ezixutywe ngomxube owomileyo, iimveliso zesamente kunye neekhompawundi zokuzilinganisa. Zinikezela ngokunamathela okuhle kakhulu, ukuguquguquka kunye nokuqina.
2. I-polymer enokuphinde inyibilike ye-acrylic
Iipolymers eziphinda zichithwe nge-acrylic zenziwe ngee-acrylic okanye ii-methacrylic copolymers. Amandla azo angaqhelekanga kunye nokumelana nokukrala kuzenza zilungele ukusetyenziswa apho ukuqina kubaluleke kakhulu. Zisetyenziswa kwi-adhesives zethayile, kwiinkqubo zokugquma zangaphandle kunye neenkqubo zokugqiba (EIFS), kunye nee-mortars zokulungisa.
3. I-ethylene-vinyl acetate i-polymer ephinda inyibilike
Iipolymers eziphinda zinyibilike ze-ethylene-vinyl acetate zenziwe ngee-ethylene-vinyl acetate copolymers. Zisetyenziswa kwiindlela ezahlukeneyo zokusetyenziswa kuquka iimortar zesamente, ii-grouts kunye nee-adhesive zethayile. Zinokuguquguquka okugqwesileyo kunye nokunamathela okufanelekileyo kokusetyenziswa kwiindawo ezixineneyo.
4. I-polymer ephinda inyibilike nge-styrene-butadiene
Iipolymers eziphinda zinyibilike nge-styrene-butadiene zenziwe ngee-copolymers ze-styrene-butadiene. Zisetyenziswa kwiindlela ezahlukeneyo zokusetyenziswa kuquka iimortars zokulungisa i-concrete, ii-adhesives zethayile kunye nee-grouts. Zinokumelana kakuhle namanzi kunye neempawu zokuncamathelisa.
5. Umgubo wepolymer ophinda uxutywe
Umgubo wepolymer ophinda uxutywe yi-RDP eyenzelwe ukuphinda uxutywe emanzini emva kokomiswa. Isetyenziswa kwiindawo ezininzi apho imveliso ivezwa emanzini okanye kumswakama emva kokusetyenziswa. Ezi ziquka izincamathelisi zethayile, i-grout, kunye ne-caulk. Zinokumelana nokungangeni manzi kakuhle kwaye ziguquguquka.
6. Umgubo wepolymer ophinda unyibilike ngamanzi
Iipowder zepolymer eziphinda zinyibilike nge-hydrophobic ezenzelwe ukwandisa ukumelana namanzi kweemveliso ezisekwe kwisamente. Ihlala isetyenziswa kwiindawo apho imveliso iya kudibana namanzi, njenge-Exterior Insulation and Finishing Systems (EIFS), izincamathelisi zethayile zedama lokudada kunye neemortar zokulungisa i-concrete. Inokumelana namanzi okugqwesileyo kunye nokuqina kwayo.
I-Redispersible latex powder yinto enokusebenziseka ngeendlela ezininzi engasetyenziswa kwiindawo ezininzi. Kukho iintlobo ezahlukeneyo ze-RDP, nganye ineempawu zayo kunye nemisebenzi yayo eyahlukileyo. Ukunamathela kwazo okuhle, ukuguquguquka kunye nokuqina kwazo kuzenza zilungele ukusetyenziswa kwiintlobo ngeentlobo zeemveliso. Xa zisetyenziswa ngokuchanekileyo, zinokunceda ukuphucula umgangatho kunye nobude bexesha leemveliso ezininzi zokwakha.
