Redispersible Polymer Powder (RDP) bụ polymer ejiri mee ihe n'ụdị dị iche iche. RDP bụ ntụ ntụ na-agbaze mmiri nke sitere na ụdị polymers dị iche iche, gụnyere vinyl acetate, vinyl acetate ethylene, na resin acrylic. A na-agwakọta ntụ ntụ na mmiri na ihe mgbakwunye ndị ọzọ iji mepụta slurry, nke a na-etinye ya na ihe dị iche iche. Enwere ụdị RDP dị iche iche, nke ọ bụla nwere njirimara na ojiji ya pụrụ iche. N'ime edemede a, anyị ga-enyocha ụfọdụ ụdị RDP kachasị na ngwa ha.
1. Vinyl acetate redispersible polymer
Vinyl acetate redispersible polymers bụ ụdị RDP kachasị. A na-eme ha site na vinyl acetate na vinyl acetate ethylene copolymer. A na-agbasasị ihe ndị ahụ polymer n'ime mmiri ma nwee ike ịmeghachi ya n'ọnọdụ mmiri mmiri. Ụdị RDP a nwere ngwa dịgasị iche iche gụnyere ngwa ngwa mix mix, ngwaahịa ciment na ogige nke onwe. Ha na-enye ezigbo adhesion, mgbanwe na ogologo oge.
2. polymer redispersible acrylic
A na-eme polymer redispersible acrylic site na acrylic ma ọ bụ methacrylic copolymers. Ike ha pụrụ iche na nguzogide abrasion na-eme ka ha dị mma maka ngwa ebe ịdịte aka dị oke mkpa. A na-eji ha eme ihe na nrapado taịlị, mkpuchi mpụta na sistem imecha (EIFS), na ịrụkwa ngwa agha.
3. Ethylene-vinyl acetate redispersible polymer
Etylene-vinyl acetate redispersible polymers na-mere si ethylene-vinyl acetate copolymers. A na-eji ha na ngwa dị iche iche gụnyere ngwa ngwa ciment, grouts na tile adhesives. Ha nwere ezigbo mgbanwe na adhesion maka iji na gburugburu nrụgide dị elu.
4. Styrene-butadiene redispersible polymer
A na-emepụta polymers Styrene-butadiene redispersible site na styrene-butadiene copolymers. A na-eji ha eme ihe n'ụdị dị iche iche gụnyere ngwa nrụzi ihe, ihe ntanye tile na grouts. Ha nwere ezigbo nguzogide mmiri na ihe nrapado.
5. Re-emulsifiable polymer ntụ ntụ
A na-emegharị polymer ntụ ntụ bụ RDP emebere ka e megharịa ya na mmiri mgbe ihichachara. A na-eji ya n'ọtụtụ ngwa ebe ngwaahịa na-ekpuchi mmiri ma ọ bụ mmiri mgbe ejiri ya. Ndị a na-agụnye adhesives tile, grout, na caulk. Ha nwere ezigbo nguzogide mmiri na mgbanwe.
6. Hydrophobic redispersible polymer ntụ ntụ
Hydrophobic redispersible polymer powders emebere iji mee ka mmiri na-eguzogide ngwaahịa sitere na ciment. A na-ejikarị ya na ngwa ebe ngwaahịa a ga-abanye na mmiri, dị ka Mpụga mkpuchi na Finishing Systems (EIFS), ebe igwu mmiri tile adhesives na ihe nrụzi ngwa agha. Ọ nwere ezigbo nguzogide mmiri na ogologo oge.
Redispersible latex ntụ ntụ bụ ihe dị iche iche nwere ike iji mee ihe n'ọtụtụ ngwa. Enwere ụdị RDP dị iche iche, nke ọ bụla nwere njirimara na ojiji ya pụrụ iche. Ngwunye ha dị mma, mgbanwe na ịdịte aka na-eme ka ha dị mma maka iji ngwaahịa dị iche iche. Mgbe ejiri ya mee ihe nke ọma, ha nwere ike inye aka melite ogo na ogologo ndụ nke ọtụtụ ngwaahịa ụlọ.
