Kedu ihe bụ ntụ ntụ Polymer Redispersible?

Polima ntụ ntụ na-agbanwe agbanwe(RPP) bụ ntụ ntụ na-acha ọcha nke na-agbapụta n'efu, nke enwetara site na emulsions polymer na-ekpochapụ.Ọ mejupụtara polymer resin ahụ na-achụsasịwo na mmiri na-etolite emulsion, nke a na-akpọnwụrụ n'ime a ntụ ntụ ụdị.RPP nwere ngwakọta nke polymers, nke na-abụkarị vinyl acetate ethylene (VAE), vinyl acetate versatate (Vac/VeoVa), acrylics, na ndị ọzọ copolymers.A na-ahọrọ polymers ndị a dabere na njirimara ha na ngwa ha chọrọ.

Nke a bụ ụfọdụ njirimara na njirimara nke ntụ ntụ polymer redispersible:

1. Nhazi ihe nkiri: Mgbe agwakọtara ya na mmiri, ihe ndị RPP na-agbasa ọzọ wee mepụta ihe nkiri polymer na-agbanwe agbanwe mgbe ihicha.Ihe nkiri a na-enye nchikota, nchikota, na ogologo oge na ihe dị iche iche dị iche iche, dị ka ihe, ngwa agha, nrapado tile, na mkpuchi.
2. Adhesion: RPP na-eme ka adhesion dị n'etiti ihe dị iche iche, gụnyere ihe ndị na-emepụta ihe na mkpuchi, tile na adhesives, na fibers na binders.Ọ na-eme ka ike nkekọ dịkwuo mma ma gbochie delamination ma ọ bụ mwepu nke ihe ka oge na-aga.
3. Mgbanwe: RPP na-enye mgbanwe na mkpuchi, adhesives, na ngwa agha, na-enye ha ohere ịnweta mmegharị mkpụrụ, mgbasawanye ọkụ, na nrụgide ndị ọzọ na-enweghị mgbawa ma ọ bụ ọdịda.Ihe onwunwe a dị oke mkpa maka idobe iguzosi ike n'ezi ihe nke ihe etinyere.
4. Mgbochi mmiri: RPP na-eme ka mmiri na-eguzogide mmiri nke usoro, na-eme ka ha dị mma maka gburugburu ma ọ bụ ebe mmiri.Ọ na-enyere aka igbochi ịbanye mmiri ma na-echebe ihe ndị dị n'okpuru na mmebi.
5. Ogologo oge: RPP na-akwalite ịdịte aka na ihu igwe nke ihe site na imeziwanye nguzogide ha na radieshon UV, mkpughe kemịkalụ, abrasion, na ịka nká.Ọ na-agbatị ndụ ndụ nke mkpuchi, nrapado, na ngwa agha, na-ebelata ihe ndozi na ụgwọ ọrụ.
6. Ịrụ ọrụ: RPP na-eme ka arụ ọrụ na nhazi nhazi nke nhazi site na imeziwanye usoro, ọkwa, na mgbasawanye.Ọ na-eme ka mkpuchi otu, ngwa dị nro, yana ịrụ ọrụ na-agbanwe agbanwe nke ihe etinyere.
7. Njikwa Rheology: RPP na-eje ozi dị ka onye na-emegharị rheology, na-emetụta viscosity, thixotropy, na sag resistance nke usoro.Ọ na-enyere aka ịkwalite njirimara ngwa na arụmọrụ nke mkpuchi, adhesives, na ngwa agha.
8. Ndakọrịta: RPP dakọtara na ọtụtụ ihe mgbakwunye ndị ọzọ, ihe ndochi, pigmenti, na ihe nkedo a na-ejikarị eme ihe.Ọ naghị emetụta ihe onwunwe ma ọ bụ arụmọrụ nke ihe ndị ọzọ, na-eme ka nkwụsi ike na nkwụsi ike.

polymer ntụ ntụ na-agbanwe agbanwe na-achọta ọtụtụ ojiji na ngwa ihe owuwu, gụnyere nrapado taịlị, ngwa ngwa sitere na ciment, ogige na-edozi onwe ya, akpụkpọ mmiri na-egbochi mmiri, na nrụzi ngwa agha.Ọ nwekwara ngwa na mkpuchi, adhesives, sealants, textiles, na ụlọ ọrụ akwụkwọ, na-enye aka na arụmọrụ na ịdịte aka nke ihe dị iche iche na ngwaahịa.
