Ntụ ntụ Polymer nke dabeere na VeoVa

Polymer powder (RDP) dabere na VeoVa bụ ụdị mgbakwunye polymer ntụ ntụ a na-ejikarị eme ihe n'ihe owuwu, dị ka ngwa agha, nrapado taịlị, na ihe ntụgharị. VeoVa na-ezo aka na ezinụlọ nke vinyl ester monomers sitere na vinyl acetate na versatic acid. Nke a bụ nyocha nke RDP dabere na VeoVa:

1. Ihe mejupụtara:

• Ndị RDP dabere na VeoVa bụ copolymers sitere na vinyl acetate (VA) na VeoVa monomers. Usoro copolymerization na-ejikọta monomers ndị a iji mepụta polymer nwere ihe ndị a kapịrị ọnụ ahaziri maka ngwa dị iche iche.

2. Ngwongwo:

• RDP ndị dabeere na VeoVa na-enye ọtụtụ ihe ndị a na-achọsi ike, gụnyere mma mmachi, mgbanwe, mmiri na-eguzogide, na ịdịte aka.
• Ntinye nke VeoVa monomers n'ime ihe owuwu polymer na-eme ka arụmọrụ RDP dịkwuo elu ma e jiri ya tụnyere RDP omenala VA na ngwa ụfọdụ, karịsịa ndị chọrọ mgbanwe dị elu na nkwụsị mmiri.

3. Ngwa:

• A na-eji RDP nke VeoVa eme ihe n'ụdị ihe owuwu dị iche iche, gụnyere ngwa agha, adhesives tile, grouts, ogige na-edozi onwe ya, na mkpuchi mmiri.
• Ha na-adabara nke ọma maka ngwa ebe a na-achọwanye mgbanwe mgbanwe na mmiri na-eguzogide mmiri, dị ka ndị na-emepụta ihe dị n'èzí, polymer-modified cementity cover, na usoro mkpuchi mmiri.

4. Uru:

• Mgbanwe mgbanwe emelitere: RDP dabere na VeoVa na-enye nkwalite mgbanwe, na-enye ha ohere iguzogide mmegharị mkpụrụ na mgbanwe okpomọkụ na-enweghị mgbawa.
• Enwetara Mgbochi Mmiri: Ọnụnọ nke VeoVa monomers na-eme ka mmiri na-eguzogide mmiri nke RDPs, na-eme ka ha dị mma maka ngwa mpụga nke ekpughere na ọnọdụ ihu igwe siri ike.
• Adhesion Kasị Elu: RDP nke dabere na VeoVa na-enye ezigbo mmachi n'ụdị dị iche iche, gụnyere kọmpụta, masonry, osisi, na bọọdụ mkpuchi, na-eme ka njikọ siri ike na ịdịte aka ogologo oge.

5. ndakọrịta:

• RDP dabere na VeoVa dakọtara na mgbakwunye ndị ọzọ a na-ejikarị eme ihe n'ihe owuwu, dị ka simenti, ihe ndochi, plasticizers, na ihe ndị na-enye ikuku. Ndakọrịta a na-enye ohere ịmepụta ngwa ngwa ahaziri ahazi na usoro nrapado ahaziri maka ngwa achọrọ.

Na nchịkọta, VeoVa dabeere redispersible polymer powders (RDPs) na-enye nkwalite mgbanwe, mmiri na-eguzogide, na adhesion tụnyere omenala VA dabeere RDPs, na-eme ka ha dabara nke ọma maka ọtụtụ ụdị ihe owuwu ngwa ebe ịdịte aka na arụmọrụ dị oké mkpa.
