Musiyano uripo pakati pePVDF uye poda coating
Vanhu vazhinji havazive nezvePVDF uye kupfekedza hupfu.Nhasi ini ndichatsanangura musiyano pakati pePVDF uye poda coating zvakadzama.
1. Pendi yakashandiswa
PaPVDF, pendi inoshandiswa ndeyePVDF fluorocarbon pendi uye PVDF yakakosha primer, ese ari ese ari anonyungudutsa-based liquid pendi.
Pakuputira poda, iko kupfekedza kunoshandiswa kupfekedza hupfu, kunowanzozivikanwa sehupfu hwepurasitiki.Mhando huru ndeiyi: epoxy polyester poda coating (indoor epurasitiki poda), polyester poda coating (field plastic poda), epoxy powder coating (anticorrosive powder).Powder coatings is solvent-free solid coatings.
2. Kupfapfaidza michina
Ose ari maviri upfu coating uye PVDF akakodzera gungano mutsetse spraying.
PVDF coating inogona kuva electrostatic spraying kana general spraying.
Electrostatic spraying, friction gun spraying, fluidized bed spraying nedzimwe nzira dzinoshandiswa pakuputira hupfu.Yekutanga ndeye electrostatic spraying.
3. Kupisa kwekubika
PVDF coating kubheka bvunzo tembiricha: 230°C, 15min.
Poda yekubikira tembiricha yekubikira: yemukati epurasitiki poda 180鈩?20min;kunze kwepurasitiki poda: 200鈩?20min;
4. Kuramba kwemamiriro ekunze(kunze kweUV kuramba, kutsvuka kweyero, kupenya uye kuchengetedza kwemavara, mhepo uye kushorwa kwezuva)
PVDF: anopfuura makore gumi nemashanu,
Powder coating (pure polyester powder), makore 7-8.
Asi marudzi maviri aya ekupfapfaidza anogona kugadzirwa zvinoenderana neAmerican standard AAMA, senge AAMA 2604, AAMA 2605…
5. Pendi firimu ukobvu
PVDF: 35-60um.
Powder coating: 60-120um, zvichienderana nerudzi rwemusiyano.
6. Chitarisiko
PVDF: yakajeka, simbi.Iyo gloss kazhinji haina kukwirira.
