Thermosetting Powder Coating For Electrostatic Spraying

Sebopeho sa phofshoana ea phofo bakeng sa theknoloji ea ho fafatsa ka electrostatic e fapane ka ho feletseng le liaparo tse tloaelehileng 'me e teng sebakeng sa phofo e ntle. Kaha ha ho na solvent, li bitsoa powder coatings. Litšobotsi tse ka sehloohong tsa ho roala phofo ke: ho se kotsi, ho sebetsa hantle, ho boloka mehloli le ho boloka tikoloho.

Thermosetting powder ke mofuta o sebelisoang hangata oa electrostatic spraying powder le e 'ngoe ea pele e lokelang ho ntlafatsoa le ho sebelisoa. E na le boima bo phahameng, khanyetso e ntle ea lik'hemik'hale le ho hanyetsa mocheso o phahameng haholo, 'me e sebelisoa haholo ho roala liindasteri, ho etsa thepa, ho haha ​​le libakeng tse ling. E sebelisoa hangata li-thermosetting powders li kenyelletsa epoxy, polyester, acrylate le polyether.

Electrostatic spraying powder coatings ka kakaretso e arotsoe ka mekhahlelo e 'meli: thermoplastic powder coatings le thermosetting powder coatings.

1. Ho roala ka phofo ea thermoplastic

Thermoplastic phofo e koahelang e na le thermoplastic, pigment, filler, binder le stabilizer. Thermoplastic phofo coatings kenyeletsa: polyethylene, polypropylene, polyester, PVC, chlorinated polyether, polyamide, selulose, polyester joalo-joalo.

2. Liaparo tsa phofo tsa thermosetting

Thermosetting phofo e koahelang e na le resin ea thermosetting, e phekolang, pigment, filler le additives. Thermosetting phofo e koahelang e kenyelletsa: epoxy resin, epoxy polyester, polyester, polyurethane, acrylic resin joalo-joalo.

Phofo ea polasetiki e ka aroloa ka phofo ea thermoplastic le phofo ea thermosetting; phofo ea ka ntle le phofo ea ka hare; phofo e hanyetsanang le mocheso o phahameng le phofo e tlaase ea mocheso.

1. Melemo ea phofo ea polasetiki ea thermoplastic ke ho tiea, ho khumama hantle, ho hanyetsa lik'hemik'hale, 'me e ka sebelisoa ho koahela filimi e teteaneng ea ho roala.

2. Molemo oa phofo ea ka hare ke hore ts'ebetso e fokola ho feta phofo ea ka ntle, e ka sebelisoa bakeng sa ho roala ka hare ho workpiece, theko e batla e le theko e tlaase.

3. Phofo e phahameng ea mocheso e ka mamella mocheso o phahameng oa likhato tse 200 ka nako e telele 'me ho roala ha ho fetole' mala, thepa ea 'mele le ea mechine ea sebaka se amohelehang.

4. Thermosetting phofo ka mocheso kamoreng ke ke nolofatsa le agglomeration, molemo mechine qhalakana, ho le bonolo ho theha a bataletseng barbota filimi filimi.

5. Phofo e ka ntle e loketse ho roala ha mosebetsi oa ka ntle, o nang le antioxidant, anti-ultraviolet ray, anti-acid le moholi oa alkali le pula, katoloso e ntle ea mocheso le ts'ebetso ea ho fokotsa.

6. Phofo e nang le mocheso o tlase e khona ho kenella filiming ea ho roala ka likhato tse 80-150 tsa Celsius, 'me e ka sebelisoa holim'a lehong le polasetiki.
