Electrostatic Spray Thermoplastic Powder Coating

PECOAT® Electrostatic spray thermoplastic powder coating is a thermoplastic poda yakagadzirwa kubva ku polyethylene resin, comptibilizer, inoshanda additives, pigments uye fillers. Iyo ine yakanakisa adhesion uye anti-corrosive zvivakwa, pamwe nekugadzikana kwakanaka kwemakemikari, kuvharwa kwemagetsi uye kushomeka kwekushisa. Inogona kugadzirwa maererano nezvinodiwa nevatengi. Kuenzaniswa neyakajairwa PE poda yekupotera, chinhu chayo chikuru kutetepa, iyo inogona kupfapfaidzwa mune zvese zvinotonhora basa-chidimbu uye preheated basa-chidimbu. Inokodzerawo fluidized bed dipping process.

unhu

1. Yakasiyana-siyana nzira yekushandisa: electrostatic spray, fluidized bed dip, blockspaying
2. Mutete wakapfava, Diki particle size
3. Inokodzera kutonhora workpiece uye preheated workpiece

shandisa

Mhando dzakasiyana dzemakemikari emidziyo, mapaipi emaindasitiri, uye zvikamu zvesimbi. Inonyanya kushanda kune yakaoma basa-zvidimbu.

Shandisa Nzira ye electrostatic spray thermoplastic powder coating

1.Fluidized Bed

Pakunyudzwa-pamubhedha, preheat zvikamu kusvika 230°C kugadzirisa kune chikamu chakakora. Nyura zvikamu mu-fluidized-mubhedha kwe8-10 seconds. Bvumira hupfu hwakawandisa kuti umire kweminiti 1 wobva wanyatsofuridza zvinhu zvakawandisa. Post-kupisa pa 193 - 205 ° C kwemaminitsi 3 - 4.

2.Electrostatic Deposition

PECOAT® Electrostatic spray thermoplastic polyethylene poda coating inogona kuiswa kuburikidza ne electrostatic deposition ine kana isina pre-kupisa.

• Kana usingashandisi pre-heat, hupfu hunofanira kuiswa kuti huwane kukora 203 - 254µm. Inokurudzirwa kuseta magetsi paunenge uchishandisa Corona midziyo ndeye 40 - 60 kv. Post-heating pa 175 - 220 ° C kwemaminetsi mashanu kusvika gumi zvichienderana nekukora kwesimbi, kana kusvika kuda kubuda kunze kwaitwa.
• Pazvikamu zvinopisa, tembiricha yepreheat inokurudzirwa i205°C. Deposit 203 - 300µm kana kupfuura kana uchida. Kuti uwedzere kupera kwepamusoro, zvikamu zvinogona kupiswa-kumashure kwenguva pfupi kana zvichidikanwa. Nguva uye tembiricha muchoto zvinoenderana nekumisikidzwa uye ukobvu hwechikamu.

Kurongedza uye Kuchengeta kwe electrostatic spray thermoplastic poda

25kg / bhegi, Yakachengetwa munzvimbo yakachena yakaoma isingasviki 40 ℃ uye kunze kwezuva, nguva yekuchengetedza makore maviri. Mushure mekupera, inogona kushandiswa kana pasina dambudziko remhando mushure mekuedzwa. PECOAT® Electrostatic spray thermoplastic powder coating haigoni kusanganiswa nehupfu kubva kune mumwe mutengesi.

Utano uye kuchengeteka

PECOAT® Electrostatic spray thermoplastic powder coating haina chepfu uye haina kukuvadza. Nekudaro, inhalation yeguruva inofanira kudziviswa panguva yekushandiswa. Zvinokurudzirwa kuti vashandisi vapfeke masiki eguruva akakodzera uye magirazi. Kana zvichibvira, edza kudzivisa kubata kwenguva refu kweganda nehupfu.
