Acrylic Powder Coatings ke Eng
Acrylic phofo ea ho roala na le thepa e babatsehang ea mokhabiso, ho hanyetsa boemo ba leholimo, le ho hanyetsa tšilafalo, le ho ba le boima bo phahameng ba holim'a metsi. Ho tenyetseha hantle. Empa theko e holimo mme ho hanyetsa ho bola hoa fokola. Ka hona, linaha tsa Europe liphatsa tsa lefutsoralsebelisa phofo e hloekileng ea polyester (resin e nang le carboxyl, e phekotsoeng ka TGIC); (hydroxyl-containing polyester resin e phekoloa ka isocyanate) e le lesela la phofo le hanyetsanang le boemo ba leholimo.
Sebopeho
Liaparo tsa phofo tsa Acrylic li entsoe ka li-resin tsa acrylic, li-pigment le li-filler, li-additives le lisebelisoa tsa ho folisa.
Types
Ka lebaka la lihlopha tse fapaneng tse sebetsang tse teng mohahong oa limolek'hule, li-resin tsa acrylic li na le mefuta e latelang:
1. Acrylic resin e nang le sehlopha se sebetsang sa glycidyl ether.
2. Acrylic resin e nang le sehlopha se sebetsang sa carboxyl.
3. Acrylic resin e nang le sehlopha se sebetsang sa hydroxyl.
Phekolo Maemo
Ka lebaka la meaho e fapaneng le lihlopha tse sebetsang tse fumanehang ka har'a li-resin tsa acrylic, lisebelisoa tse khethiloeng tsa pheko le mekhoa ea ho folisa le tsona li fapane. Ka mor'a ho hokahanya, thepa ea 'mele le ea lik'hemik'hale le eona e fapane.
Maemo a ho folisa a litlolo tsa phofo ea acrylic ke:
Pheko ea mocheso: 180 ℃ ~ 200 ℃;
Nako ea ho folisa: 15min ~ 20min;
Mekhoa ea ts'ebeliso ea liphahlo tsa phofo ea thermosetting e ka sebelisoa bakeng sa ho roala phofo ea acrylic.
Tshebetso ea ho hlahisa
Ho na le mekhoa e mene ea tlhahiso ea ho roala phofo ea acrylic:
E 'ngoe ke mokhoa oa ho fetoha mouoane.
Ea bobeli ke mokhoa oa ho omisa.
Ea boraro ke mokhoa o metsi.
Qetellong, e tšoana le mokhoa oa tlhahiso ea ho roala phofo ea epoxy.
Mokhoa oa bone oa tlhahiso o sebelisoa haholo-holo.
Ts'ebetso e tjena:
Ho kopanya → extrusion → ho pshatla → sieving → sephuthelo
