O le a le pauta polymer toe fa'asalalauina?
Redispersible polymer powders (RPP) e tafe fua, pa'epa'e pa'epa'e e gaosia e fa'amago fa'amago polymer dispersions po'o emulsions. E aofia ai ni vaega polymer o loʻo faʻapipiʻiina i mea puipuia ma faʻaopoopoga. Pe a faʻafefiloi ma le vai, o nei paʻu e faigofie ona taape e fausia ai ni polymer emulsions mautu, e mafai ai ona latou faʻaogaina i le tele o faʻaoga i le fausiaina, vali ma faʻapipiʻi, faʻapipiʻi, ma isi pisinisi.
Tulaga:
O le tu'ufa'atasiga o pa'u polymer toe fa'asalalau e masani ona aofia ai vaega nei:
- Polymer Particles: O le vaega muamua o le RPP o mea faʻameamea, lea e maua mai i polymers synthetic eseese e pei o le vinyl acetate-ethylene (VAE), ethylene-vinyl acetate (EVA), acrylics, styrene-butadiene (SB), poʻo le polyvinyl acetate ( PVA). O nei polymers e saofagā i meatotino manaʻomia ma uiga faʻatinoga o le oloa mulimuli.
- Vaega Puipuia: Ina ia puipuia le polymer particles mai le faʻapipiʻiina i le taimi o le teuina ma le felauaiga, o mea e puipuia ai e pei ole polyvinyl alcohol (PVA) poʻo cellulose ethers e masani ona faʻaaogaina. O nei vailaʻau faʻamautu le polymer particles ma faʻamautinoa lo latou toe faʻasalalau i le vai.
- Plasticizers: E mafai ona faʻapipiʻi mea faʻapipiʻi e faʻaleleia ai le fetuutuunai, galue, ma le pipii o RPPs. O nei mea fa'aopoopo e fesoasoani e fa'amalieina le fa'atinoga o vaega polymer i fa'aoga 'ese'ese, aemaise i fa'alavalava fe'ai, fa'apipi'i, ma fa'amaufa'ailoga.
- Fillers and Additives: Faʻalagolago i manaʻoga faʻapitoa faʻaoga, faʻatumu, pigments, crosslinking agents, thickeners, ma isi faʻaopoopoga e mafai ona tuʻufaʻatasia i totonu o le RPP formulations e faʻaleleia ai a latou meatotino pe tuʻuina atu galuega faʻapitoa.
Meatotino ma Uiga:
Redispersible polymer powders o loʻo faʻaalia ai le tele o mea taua ma uiga e faʻaogaina ai ma faʻaaogaina lautele i pisinisi eseese:
- Redispersibility: RPP faigofie ona taape i totonu o le vai e fausia ai polymer emulsions mautu poʻo faʻasalalau, faʻataga mo le faʻaogaina faigofie i faʻasologa ma le faʻaogaina mulimuli ane.
- Ata-Faiga Ata: A faʻasalalau i le vai ma faʻaoga i luga o luga, e mafai e le RPP ona fausia ni ata manifinifi, faʻaauau pea pe a faʻamago. O nei ata tifaga e faʻaleleia ai le pipii, tumau, ma le faʻafefe o le tau i paʻu, faʻapipiʻi, ma faʻamaufaʻailoga.
- Faʻaleleia le Faʻapipiʻi: RPP faʻaleleia le faʻapipiʻiina i le va o mea faʻapipiʻi ma mea faʻapipiʻi, morta, poʻo mea faʻapipiʻi, e mafua ai le malosi o faʻamau ma faʻaleleia le faʻatinoga i le fausiaina ma mea fau fale.
- Taofi Suavai: O le natura hydrophilic o le RPP e mafai ai ona latou mitiia ma taofi le vai i totonu o faʻavae, faʻaumiumi le faʻamamaina ma faʻaleleia atili galuega, taimi tatala, ma faʻapipiʻi i le sima ma le faʻapipiʻi faʻapipiʻi.
- Fetuutuuna'i ma Malosi: O mea e faʻaleleia e le RPP e faʻaalia ai le faʻalauteleina o le fetuutuunai, elasticity, ma le faigata, ma faʻamalosia atili ai i latou i le taʻe, faʻaleagaina, ma aʻafiaga faʻaleagaina.
- Faʻasagaga o le Tau: O le RPP e faʻaleleia ai le faʻafefe o le tau ma le umi o le ufiufi, faʻamaufaʻailoga, ma le faʻafefe o le susu, e maua ai le puipuiga umi mai le faʻavelaina o le UV, susu, ma mea tau le siosiomaga.
Talosaga:
Redispersible polymer powders maua talosaga i le tele o alamanuia ma oloa, e aofia ai:
- Faufale: Fa'apipi'i ta'i, sima, pa'u, pa'u e fa'asusu le susu, fa'apipi'i fa'alelei, ma fa'a'ese'ese fafo ma fa'auma (EIFS).
- Vali ma Fa'ava'a: Vali fafo, fa'alava fa'alava, fa'amea teuteu, ma fa'afale fa'afale.
- Fa'apipi'i ma Fa'amau: Fa'apipi'i fa'ameamea, fa'ama'ei ta'ei, fa'ama'i, fa'amaufa'ailoga fetu'utu'una'i, ma mea fa'apipi'i fa'aoso.
- I'emea: La'ei ie, mea fa'auma, ma fa'aputuga fa'aputu.
redispersible polymer powders o mea faʻapitoa ma multifunctional e faʻaaogaina e faʻaleleia ai le faʻatinoga, tumau, ma le faʻaogaina o oloa eseese ma faʻavae i le fausiaina, vali ma faʻaofuofu, faʻapipiʻi, ie, ma isi pisinisi.
