Mitundu yosiyanasiyana ya Redispersible Polymer powders
Redispersible polymer powders (RDPs) amabwera m'mitundu yosiyanasiyana, iliyonse ili ndi mawonekedwe apadera ogwirizana ndi kagwiritsidwe ntchito kake komanso zofunikira pakuchita. Nayi mitundu yodziwika bwino ya ufa wa polima wotulukanso:
1. Vinyl Acetate Ethylene (VAE) Copolymers:
- Ma VAE copolymers ndi omwe amagwiritsidwa ntchito kwambiri pa RDPs.
- Amapereka kumamatira kwabwino, kusinthasintha, komanso kukana madzi.
- Ma VAE RDPs ndi oyenerera ntchito zosiyanasiyana, kuphatikizapo zomatira matailosi, EIFS (Exterior Insulation and Finish Systems), mankhwala odzipangira okha, ndi ma membranes oletsa madzi.
2. Vinyl Acetate Versatate (VAV) Copolymers:
- VAV copolymers ndi ofanana ndi VAE copolymers koma ali ndi gawo lalikulu la vinyl acetate monomers.
- Amapereka mawonekedwe osinthika komanso otalikirapo, kuwapangitsa kukhala oyenera kugwiritsa ntchito zomwe zimafunikira kusinthasintha kwakukulu komanso kukana ming'alu.
3. Acrylic Redispersible Ufa:
- Acrylic RDPs imapereka kulimba kwabwino, kukana nyengo, komanso kukhazikika kwa UV.
- Amagwiritsidwa ntchito kwambiri popangira zokutira kunja, utoto, ndi zosindikizira pomwe kuchita kwanthawi yayitali ndikofunikira.
4. Ethylene Vinyl Chloride (EVC) Copolymers:
- EVC copolymers amaphatikiza katundu wa vinyl acetate ndi vinyl chloride monomers.
- Amapereka kukana kwamadzi kowonjezereka komanso kukana kwa mankhwala, kuwapangitsa kukhala oyenera kugwiritsidwa ntchito m'malo ovuta.
5. Styrene Butadiene (SB) Copolymers:
- Ma copolymer a SB amapereka mphamvu zolimba kwambiri, kukana kukhudzidwa, komanso kukana abrasion.
- Nthawi zambiri amagwiritsidwa ntchito pazinthu za simenti monga matope okonzera konkriti, ma grouts, ndi zokutira.
6. Ethylene Vinyl Acetate (EVA) Copolymers:
- Ma copolymer a EVA amapereka kusinthasintha, kumamatira, ndi mphamvu.
- Amagwiritsidwa ntchito kwambiri pomatira matailosi, ma pulasitala, ndi zinthu zolumikizirana pomwe kusinthasintha ndi mphamvu zomangira ndizofunikira.
7. Ufa Wophatikizanso Wophatikiza:
- Ma Hybrid RDP amaphatikiza mitundu iwiri kapena kuposerapo kuti akwaniritse magwiridwe antchito.
- Mwachitsanzo, RDP yosakanizidwa imatha kuphatikiza ma polima a VAE ndi acrylic kuti athandizire kumamatira komanso kukana nyengo.
8. Specialty Redispersible Ufa:
- Ma RDP apadera amapangidwira ntchito za niche zomwe zimafuna katundu wapadera.
- Zitsanzo zikuphatikizapo ma RDP okhala ndi mphamvu zowonjezera madzi, kukana kuzizira, kapena kufalikiranso mofulumira.
Pomaliza:
Mafuta opangidwanso a polima opangidwanso amabwera m'mitundu yosiyanasiyana, iliyonse imapereka mawonekedwe ake komanso maubwino pazogwiritsa ntchito zosiyanasiyana. Posankha mtundu woyenerera wa RDP kutengera zofunikira za polojekiti kapena kapangidwe kake, opanga amatha kukulitsa magwiridwe antchito, kulimba, ndi magwiridwe antchito azinthu zawo.
