Phapang pakeng tsa PVDF le ho roala phofo
Batho ba bangata ha ba tsebe ka PVDF le ho roala phofo.Kajeno ke tla hlalosa phapang pakeng tsa PVDF le phofo ea phofo ka ho qaqileng.
1. Pente e sebelisitsoeng
Bakeng sa PVDF, pente e sebelisoang ke PVDF fluorocarbon pente le PVDF special primer, tseo ka bobeli e leng lipente tsa mokelikeli tse thehiloeng ho solvent.
Bakeng sa ho roala phofo, seaparo se sebelisoang ke phofo ea phofo, eo hangata e tsejoang e le phofo ea polasetiki.Mefuta e ka sehloohong ke: phofshoana ea epoxy polyester (phofo ea polasetiki ea ka tlung), phofshoana ea phofo ea polyester (phofo ea polasetiki ea tšimo), phofo ea epoxy (phofo e thibelang ho bola).Liaparo tsa phofo ke liphahlo tse tiileng tse se nang solvent.
2. Theknoloji ea ho fafatsa
Ka bobeli ho roala phofo le PVDF li loketse ho fafatsa mohala oa kopano.
Ho roala ha PVDF e ka ba ho fafatsa ka electrostatic kapa ho fafatsa ka kakaretso.
Ho fafatsa ka electrostatic, ho fafatsa lithunya tsa khohlano, ho fafatsa bethe ka metsi le mekhoa e meng e sebelisoa bakeng sa ho roala phofo.Ea pele ke ho fafatsa ka electrostatic.
3. Mocheso oa ho baka
Mocheso oa tlhahlobo ea ho baka oa PVDF: 230 ° C, 15min.
Mocheso oa ho baka ka phofo: phofo ea polasetiki ea ka tlung 180鈩?20mins;phofo ea polasetiki ea kantle: 200鈩?20mins;
4. Ho hanyetsa boemo ba leholimo(khanyetso ea UV ea kantle, ho hanyetsa bosehla, ho boloka khanya le mebala, ho hanyetsa moea le letsatsi)
PVDF: lilemo tse fetang 15,
Ho roala ka phofo (phofo e hloekileng ea polyester), lilemo tse 7-8.
Empa mefuta ena e 'meli ea ho fafatsa e ka etsoa ho latela maemo a Amerika a AAMA, joalo ka AAMA 2604, AAMA 2605…
5. Pente botenya ba filimi
PVDF: 35-60um.
Ho roala ka phofo: 60-120um, ho itšetlehile ka mofuta oa phapang.
6. Ponahalo
PVDF: e hlakileng, ea tšepe.Gloss ka kakaretso ha e phahame.
Ho roala ka phofo: lipente tsa bonono tse kang 'mala o hlakileng,' mala oa tšepe, wrinkle, mohlala oa lehlabathe, joalo-joalo.
