Powder Powder nke Redispersible (RDP) bụ polima e ji eme ọtụtụ ihe. RDP bụ ntụ ntụ mmiri na-agbaze site na ọtụtụ polima, gụnyere vinyl acetate, vinyl acetate ethylene, na acrylic resins. A na-agwakọta ntụ ntụ ahụ na mmiri na ihe mgbakwunye ndị ọzọ iji mepụta slurry, nke a na-etinye na substrates dị iche iche. E nwere ọtụtụ ụdị RDP, nke ọ bụla nwere ihe pụrụ iche na ojiji ya. N'isiokwu a, anyị ga-enyocha ụfọdụ n'ime ụdị RDP kachasị na ojiji ha.
1. Vinyl acetate polima a na-agbanwe agbanwe
Vinyl acetate redispersible polymers bụ ụdị RDP kachasị ewu ewu. E ji vinyl acetate na vinyl acetate ethylene copolymer mee ha. A na-agbasasị ihe ndị ahụ na mmiri ma nwee ike ime ka ha bụrụ mmiri mmiri. Ụdị RDP a nwere ọtụtụ ihe eji eme ihe gụnyere ngwa agha akọrọ, ngwaahịa simenti na ihe ndị na-eme ka ha dị larịị. Ha na-enye ezigbo nrapado, mgbanwe na ogologo oge.
2. Acrylic redispersible polima
A na-eji acrylic ma ọ bụ methacrylic copolymers eme acrylic redispersible polymers. Ike pụrụ iche ha na iguzogide abrasion na-eme ka ha dị mma maka ojiji ebe ịdịte aka dị oke mkpa. A na-eji ha eme ihe na taịlị, ihe mkpuchi mpụga na sistemụ mmecha (EIFS), na ihe ndozi ngwa agha.
3. Ethylene-vinyl acetate polima a na-agbanwe agbanwe
E ji ethylene-vinyl acetate copolymers mee polima Ethylene-vinyl acetate redispersible. A na-eji ha eme ọtụtụ ihe dịka simenti, grouts na taịlị. Ha nwere ezigbo mgbanwe na njikọta maka ojiji na gburugburu ebe nrụgide dị elu.
4. Polima Styrene-butadiene nke a na-agbanwe agbanwe
A na-eji styrene-butadiene copolymers eme polima ndị a na-akpọ styrene-butadiene redispersible. A na-eji ha eme ọtụtụ ihe dị iche iche, gụnyere ihe e ji arụzi simenti, ihe e ji agwakọta taịlị na ihe e ji agwakọta ha. Ha nwere ezigbo ike iguzogide mmiri na ihe ndị na-arapara ha.
5. Ntụ ntụ polima a na-emegharị emegharị
Ntụ ntụ polima a na-agbanwe agbanwe bụ RDP e mere ka e mee ka ọ dịghachi mmiri mgbe ọ kpọrọ nkụ. A na-eji ya eme ihe n'ọtụtụ ebe a na-etinye ngwaahịa ahụ n'ime mmiri ma ọ bụ mmiri mgbe ejiri ya. Ndị a gụnyere ihe nrapado taịlị, grout, na caulk. Ha nwere ezigbo iguzogide mmiri na mgbanwe.
6. Ntụ ntụ polima a na-akpọ Hydrophobic redispersible
Ntụ ntụ polima a na-akpọ Hydrophobic redispersible nke e mere iji mee ka mmiri ghara iguzogide ngwaahịa ndị e ji simenti mee. A na-ejikarị ya eme ihe ebe ngwaahịa ahụ ga-ezute mmiri, dịka Mkpuchi Mpụga na Mmecha Sistemụ (EIFS), ihe mgbakwụnye taịlị ọdọ mmiri na ihe e ji arụzi simenti. O nwere ezigbo iguzogide mmiri na ogologo oge.
Ntụ ntụ latex Redispersible bụ ihe dị iche iche a pụrụ iji mee ihe n'ọtụtụ ụzọ. E nwere ọtụtụ ụdị RDP, nke ọ bụla nwere ihe pụrụ iche na ojiji ya. Nrapado ha dị mma, mgbanwe na ogologo oge ha na-eme ka ha dị mma maka iji ha mee ihe n'ọtụtụ ngwaahịa dị iche iche. Mgbe ejiri ha nke ọma, ha nwere ike inyere aka melite ịdị mma na ogologo ndụ nke ọtụtụ ngwaahịa ụlọ.
