Yintoni i-Acrylic Powder Coatings
acrylic umgubo wokugquma zineempawu ezibalaseleyo zokuhombisa, ukumelana nemozulu, kunye nokumelana nongcoliseko, kwaye zibenobulukhuni obuphezulu bomphezulu. Ukuguquguquka okuhle. Kodwa ixabiso liphezulu kwaye ukumelana nomhlwa kubi. Ngoko ke, amazwe aseYurophu generalsebenzisa i-polyester powder ecocekileyo (i-carboxyl-containing resin, ephiliswa nge-TGIC); (i-hydroxyl-containing polyester resin iphiliswa nge-isocyanate) njenge-powder-resistant-resistant powder coating.
ukwakhiwa
Iingubo ze-Acrylic powder zenziwe nge-acrylic resins, ii-pigments kunye nezigcwalisi, izongezo kunye nee-agent zokuphilisa.
iintlobo
Ngenxa yamaqela ahlukeneyo asebenzayo aqulethwe kwisakhiwo semolekyuli, iireyini ze-acrylic zinezi ntlobo zilandelayo:
1. I-Acrylic resin equkethe iqela elisebenzayo le-glycidyl ether.
2. I-Acrylic resin equkethe iqela elisebenzayo le-carboxyl.
3. I-Acrylic resin equkethe iqela elisebenzayo le-hydroxyl.
Iimeko Zokunyanga
Ngenxa yezakhiwo ezahlukeneyo kunye namaqela asebenzayo aqulethwe kwii-resin ze-acrylic, ii-agent ezikhethiweyo zokunyanga kunye neendlela zokunyanga nazo zihluke. Emva kokudibanisa, iipropati zomzimba kunye neekhemikhali nazo zihluke.
Iimeko zokunyanga ze-acrylic powder zokugquma zezi:
Ubushushu bokunyanga: 180 ℃ ~ 200 ℃;
Ixesha lokunyanga: 15min ~ 20min;
Iindlela zokusebenzisa i-thermosetting powder coatings zingasetyenziselwa i-acrylic powder coating.
Inkqubo yoPhicotho
Kukho iindlela ezine zokuvelisa i-acrylic powder coating:
Enye yeyokuba ngumphunga.
Eyesibini yindlela yokutshiza yokumisa.
Eyesithathu yindlela emanzi.
Ekugqibeleni, kuyafana nendlela yokuvelisa i-epoxy powder coating.
Indlela yesine yokuvelisa isetyenziswa kakhulu.
Inkqubo yile ilandelayo:
Ukudibanisa → ukukhupha → ukutyumza → ukuhluza → ukupakisha
