Inogona Resin Powder Kutsiva Redispersible Powder?

Resin poda uye poda inodzokororwa inoshanda zvakafanana mumidziyo yekuvaka, asi haiwanzo chinjana nekuda kwekusiyana kwezvivakwa uye maitiro ekuita. Heino kuenzanisa pakati pe resin poda uye inodzokororwa poda uye kana resin poda inogona kutsiva redispersible poda:

Resin Powder:

1. Maumbirwo: Resin poda inowanzogadzirwa kubva ku thermoplastic kana thermosetting polymers, senge polyvinyl acetate (PVA), polyvinyl doro (PVOH), kana acrylic resins.
2. Zvivakwa: Resin poda inogona kupa zvinhu zvinonamira, kusamira kwemvura, uye kugona kugadzira firimu kana yakasanganiswa nemvura kana zvimwe zvinonyungudutsa. Inogona kupa imwe nhanho yekushanduka, zvichienderana nerudzi rweresin inoshandiswa.
3. Zvishandiso: Resin poda inowanzoshandiswa mune zvinonamira, coatings, uye pendi, iyo inoshanda sebhainda kana firimu-inogadzira agent kuti ivandudze kunamatira, kusimba, uye kuramba mvura.

Redispersible Powder (RDP):

1. Kuumbwa: Redispersible poda inogadzirwa kubva ku polymer emulsions iyo yakapfapfaidzwa-yakaomeswa kuti iite fomu yehupfu yemvura-based emulsion polymers, senge vinyl acetate-ethylene (VAE) copolymers kana vinyl acetate-versatile (VAC/VeoVa) copolymers.
2. Zvivakwa: RDP inopa mvura kudhispersibility, yakagadziridzwa kunamatira, kuchinjika, kuramba mvura, uye kusimba. Inokwidziridza mashandiro ezvivakwa zvekuvaka senge madhaka, mataira anonamira, uye render.
3. Zvishandiso: RDP inoshandiswa zvakanyanya muzvigadzirwa zvekuvaka, uko inoshanda sebhainda kana kuwedzera kuvandudza kushanda, simba, uye kuita kwemateki, matani anonamira, ega-leveling makomisheni, uye zvimwe zvigadzirwa.

Kuchinjana:

Nepo resin hupfu uye hupfu hunogona kudzokororwa vachigovana zvimwe zvakafanana maererano nekunamira kwavo uye firimu-kugadzira zvivakwa, hazvigaro chinjana mumashandisirwo ekuvaka. Hezvino zvimwe zvekufunga:

1. Performance Zvinodiwa: Redispersible poda yakanyatsogadzirirwa kushandiswa mukuvaka zvinhu, zvinopa zvivakwa zvakaita semvura inodhispersibility, kuchinjika, uye kuwedzeredzwa kwekunamatira. Resin poda inogona kusapa iyo yakafanana nhanho yekuita inodiwa kune zvikumbiro zvekuvaka.
2. Kugarisana: Resin poda uye redispersible poda inogona kunge iine akasiyana makemikari anoumbwa uye kuenderana nezvimwe zvinongedzo mukugadzira. Kutsiva imwe kune imwe kunogona kukanganisa mashandiro kana zvimiro zvechigadzirwa chekupedzisira.
3. Kunyatsojeka Kwekushandisa: Redispersible poda yakagadzirirwa kushandiswa mune chaiyo yekuvakisa, nepo resin poda inogona kunyanya kushandiswa mumachira, zvinonamira, kana pendi. Sarudzo pakati pezviviri zvinoenderana nezvinodiwa chaizvo zvekushandisa.

Mukupedzisa, nepo resin hupfu uye hupfu hunodzokororwa zvichigovana zvimwe zvakafanana, hazviwanzo chinjana mune zvekuvaka. Sarudzo pakati pezviviri izvi zvinoenderana nezvinodiwa zvekushanda, kuenderana nezvimwe zvinongedzo, uye chimiro chekushandiswa kwechigadzirwa.
