Redispersible Polymer Powder (RDP) ipolymer inoshandiswa mumhando dzakasiyana dzekushandisa. RDP ipfu inonyungudika nemvura inogadzirwa kubva kune akasiyana mapolymers, anosanganisira vinyl acetate, vinyl acetate ethylene, uye acrylic resins. Iyo poda inosanganiswa nemvura uye zvimwe zvinowedzera kuti iite slurry, iyo inobva yaiswa kune akasiyana substrates. Kune akati wandei marudzi eRDP, imwe neimwe iine yayo yakasarudzika zvivakwa uye mashandisiro. Muchinyorwa chino, tichaongorora mamwe emhando dzakajairika dzeRDP uye mashandisiro adzo.
1. Vinyl acetate redispersible polymer
Vinyl acetate redispersible polymers ndiyo yakajairika mhando yeRDP. Iwo anogadzirwa kubva kuvinyl acetate uye vinyl acetate ethylene copolymer. Iwo mapolymer particles akaparadzirwa mumvura uye anogona kudzoreredzwa kuita yemvura mamiriro. Rudzi urwu rweRDP rune huwandu hwakasiyana hwekushandisa zvinosanganisira yakaoma musanganiswa dhaka, simende zvigadzirwa uye self leveling makomisheni. Ivo vanopa yakanakisa adhesion, kuchinjika uye kusimba.
2. Acrylic redispersible polymer
Acrylic redispersible polymers inogadzirwa kubva ku acrylic kana methacrylic copolymers. Simba ravo rakasarudzika uye abrasion kuramba inoita kuti ive yakanakira maapplication uko kusimba kwakakosha. Iwo anoshandiswa mumatairi adhesives, kunze kwekunze uye kupedzisa masisitimu (EIFS), uye kugadzirisa madhaka.
3. Ethylene-vinyl acetate redispersible polymer
Ethylene-vinyl acetate redispersible polymers inogadzirwa kubva ethylene-vinyl acetate copolymers. Iyo inoshandiswa mumhando dzakasiyana-siyana dzekushandisa dzinosanganisira simende dhaka, grouts uye mataira adhesives. Ivo vane yakanakisa kuchinjika uye kunamatira kuti ishandiswe munzvimbo dzakanyanya kushushikana.
4. Styrene-butadiene redispersible polymer
Styrene-butadiene redispersible polymers inogadzirwa kubva ku styrene-butadiene copolymers. Iwo anoshandiswa mumhando dzakasiyana dzekushandisa zvinosanganisira kongiri kugadzirisa madhaka, mataira anonamira uye grouts. Ivo vane yakanakisa kudzivirira kwemvura uye inonamira zvinhu.
5. Re-emulsifiable polymer powder
Re-emulsifiable polymer poda iRDP yakagadzirirwa kuiswa zvakare mumvura mushure mekuoma. Inoshandiswa mumashandisirwo mazhinji apo chigadzirwa chinoratidzwa kumvura kana unyoro mushure mekushandisa. Izvi zvinosanganisira matile adhesives, grout, uye caulk. Ivo vane yakanakisa kudzivirira kwemvura uye kuchinjika.
6. Hydrophobic redispersible polymer powder
Hydrophobic redispersible polymer poda yakagadzirirwa kuwedzera kudzivirira kwemvura yezvigadzirwa-simende. Inowanzo shandiswa mumashandisirwo ayo chigadzirwa chinosangana nemvura, senge Exterior Insulation uye Finishing Systems (EIFS), ekutuhwina mataira anonamira uye makongiri ekugadzirisa madhaka. Iyo ine yakanakisa kudzivirira kwemvura uye kusimba.
Redispersible latex poda chinhu chakasiyana-siyana chinogona kushandiswa mumashandisirwo mazhinji. Kune akati wandei marudzi eRDP, imwe neimwe iine yayo yakasarudzika zvivakwa uye mashandisiro. Kunamatira kwavo kwakanaka, kuchinjika uye kusimba kunoita kuti ive yakakodzera kushandiswa mumhando dzakasiyana dzezvigadzirwa. Kana vakashandiswa nemazvo, vanogona kubatsira kuvandudza kunaka uye hupenyu hurefu hwezvigadzirwa zvakawanda zvekuvaka.
