Thermosetting Powder Coating For Electrostatic Spraying
Tsanangudzo pfupi yehupfu
Chimiro chepoda coatings ye electrostatic spraying tekinoroji yakasiyana zvachose neyakajairwa coatings uye iripo muchimiro chehupfu hwakatsetseka. Nekuda kwekuti hapana chinonyungudutsa, anonzi mapowder coatings. Hunhu hukuru hwekuputira hupfu ndeiyi: isingakuvadzi, inoshanda, inochengetedza zviwanikwa uye ine hushamwari.
Thermosetting powder imhando inowanzoshandiswa ye electrostatic spraying powder uye imwe yekutanga kugadzirwa nekuiswa. Iyo ine kuomarara kwepamusoro, yakanakisa makemikari kuramba uye yakanakisa kupisa tembiricha kuramba, uye inoshandiswa zvakanyanya mumaindasitiri ekupfeka, kugadzira, kuvaka uye mamwe minda. Iyo inowanzoshandiswa thermosetting powders inosanganisira epoxy, polyester, acrylate uye polyether.

Normal classifications
Electrostatic spraying powder coatings anowanzo kukamurwa kuita mapoka maviri: thermoplastic poda coatings uye thermosetting poda coatings.
1. Thermoplastic powder coating
Thermoplastic poda coating ine thermoplastic, pigment, filler, binder uye stabilizer. Thermoplastic poda coatings zvinosanganisira: polyethylene, polypropylene, polyester, PVC, chlorinated polyether, polyamide, cellulose, polyester uye zvichingodaro.
2. Thermosetting powder coatings
Thermosetting poda coating ine thermosetting resin, kurapa mumiriri, pigment, filler uye additives. Thermosetting poda coatings anosanganisira: epoxy resin, epoxy polyester, polyester, polyurethane, acrylic resin uye zvichingodaro.
Zvakanakira
Plastiki poda inogona kukamurwa kuita thermoplastic poda uye thermosetting poda; poda yekunze uye poda yemukati; high-temperature-resistant poda uye yakaderera tembiricha poda.
1. Zvakanakira thermoplastic purasitiki poda kusimba, zvakanaka kukotama, kemikari kuramba, uye inogona kuiswa pakuputira yefirimu yakakora.
2. Kubatsira kwehupfu hwemukati ndeyekuti kushanda kwacho hakuna kusimba kupfuura poda yekunze, inogona kushandiswa mukati memukati workpiece coating, mutengo hausi zvishoma.
3. Kupisa kwehupfu hwepamusoro hunogona kumira kutonhora kwepamusoro kwe200 degrees kwenguva yakareba uye kuvhara hakuchinje ruvara, maitiro emuviri uye emagetsi emhando inobvumirwa.
4. Thermosetting poda pakamuri tembiricha haizopfavi uye agglomeration, yakanaka mechanical dispersion, nyore kugadzira flat coating film.
5. Outdoor poda inokodzera kunze kwekunze workpiece coating, ine antioxidant, anti-ultraviolet ray, anti-acid uye alkali fog uye mvura, kunaka kwekuwedzera kwekushisa uye kushanda kwekugadzirisa.
6. Yakaderera-tembiricha poda inokwanisa kuenzana kuita coating film pa 80-150 madhigirii Celsius, uye inogona kushandiswa pahuni nepurasitiki.
