Thermosetting poda coating inonyanya kushandiswa zvakanyanya
Thermosetting powder coating Anoshandiswa ne electrostatic spray process, inopisa kusvika kune inodiwa tembiricha uye anoporeswa uye anonyanya kuumbwa neakanyanya high molecular weightsolid resins uye crosslinker.Magadzirirwo ethermosetting powders ane maprimary resins:Epoxy,Polyester,Akriliki.
Aya maresheni ekutanga anoshandiswa neakasiyana macrosslinkers kugadzira akasiyana ehupfu zvinhu. Mazhinji macrosslinker, kana cure agents, anoshandiswa muhupfu hwekuputira, kusanganisira amines, anhydrides, melamines, uye yakavharwa kana isina-yakavharwa isocyanates.Zvimwe zvinhu zvinoshandisa zvinopfuura resin imwe mumhando dzakasanganiswa.
Kana iyo thermoset powder inoshandiswa uye ichiiswa mukupisa inonyunguduka, inoyerera uye chemikemikari yakayambuka kuti iite firimu rakapedzwa.Kemikari inopindirana muhutano hwekurapa inogadzira polymer network inopa kupikisa kwakanakisisa kuparara kwekuputira. Iyo thermoset poda yakarapa uye yakachinjika haichanyungudika uye kuyerera zvakare kana yaiswa mukupisa kechipiri.
