Kodi Redispersible Polymer Powder ndi chiyani?

Redispersible polima ufa(RPP) ndi wopanda-oyenda, ufa woyera wopezedwa ndi kupopera-kuyanika polima emulsions.Amakhala ndi polima utomoni particles kuti omwazika m'madzi kupanga emulsion, ndiyeno zouma mu mawonekedwe ufa.RPP imakhala ndi ma polima osakanikirana, omwe nthawi zambiri amakhala vinyl acetate ethylene (VAE), vinyl acetate versatate (VAc/VeoVa), ma acrylics, ndi ma copolymers ena.Ma polima awa amasankhidwa kutengera zomwe ali nazo komanso zomwe akufuna.

Nazi zina zofunika ndi katundu wa redispersible polima ufa:

1. Mapangidwe Amafilimu: Akasakanizidwa ndi madzi, tinthu tating'onoting'ono ta RPP timabalalitsanso ndikupanga filimu yosinthika ya polima ikayanika.Kanemayu amapereka kumamatira, kulumikizana, komanso kulimba kwa magawo osiyanasiyana, monga konkire, matope, zomatira matailosi, ndi zokutira.
2. Kumamatira: RPP imathandizira kumamatira pakati pa zinthu zosiyanasiyana, kuphatikiza magawo ndi zokutira, matailosi ndi zomatira, ndi ulusi ndi zomangira.Imakulitsa mphamvu ya ma bond ndikuletsa delamination kapena kutayika kwa zinthu pakapita nthawi.
3. Kusinthasintha: RPP imapereka kusinthasintha kwa zokutira, zomatira, ndi matope, kuwalola kuti azitha kusuntha gawo lapansi, kukulitsa kutentha, ndi zovuta zina popanda kusweka kapena kulephera.Katunduyu ndi wofunikira kuti asunge kukhulupirika kwa zida zogwiritsidwa ntchito.
4. Kukaniza kwa Madzi: RPP imathandizira kukana kwamadzi pamapangidwe, kuwapangitsa kukhala oyenera malo akunja kapena amvula.Zimathandiza kupewa kulowa kwa chinyezi ndikuteteza magawo omwe ali pansi kuti asawonongeke.
5. Kukhalitsa: RPP imapangitsa kuti zinthu zikhale zolimba komanso zanyengo popititsa patsogolo kukana kwawo ku radiation ya UV, kukhudzana ndi mankhwala, kuyabwa, ndi kukalamba.Imatalikitsa moyo wa zokutira, zomatira, ndi matope, kuchepetsa zofunika pakukonza ndi ndalama.
6. Kugwira ntchito: RPP imakulitsa kugwirira ntchito ndi kusinthika kwa mapangidwe powongolera kuyenda, kusanja, ndi kufalikira.Zimatsimikizira kuphimba kofanana, kugwiritsa ntchito bwino, komanso kugwira ntchito kosasinthasintha kwa zida zogwiritsidwa ntchito.
7. Rheology Control: RPP imagwira ntchito ngati rheology modifier, kukopa mamasukidwe akayendedwe, thixotropy, ndi sag resistance of formulations.Zimathandizira kukhathamiritsa kwa ntchito komanso magwiridwe antchito a zokutira, zomatira, ndi matope.
8. Kugwirizana: RPP imagwirizana ndi zina zambiri zowonjezera, zodzaza, utoto, ndi zomangira zomwe zimagwiritsidwa ntchito popanga.Sichimakhudza kwambiri katundu kapena ntchito za zigawo zina, kuonetsetsa kuti mapangidwe akhazikika komanso osasinthasintha.

Redispersible polima ufa umagwiritsidwa ntchito kwambiri pomanga, kuphatikiza zomatira matailosi, matope opangidwa ndi simenti, zodzipangira zokha, zotchingira madzi, ndi matope okonza.Ilinso ndi ntchito zopangira zokutira, zomatira, zosindikizira, nsalu, ndi mafakitale amapepala, zomwe zimathandizira kuti zida ndi zinthu zosiyanasiyana zizigwira ntchito bwino.
