Nylon Powder Electrostatic Spray Coating process

Iyo electrostatic spray nzira inoshandisa induction mhedzisiro ye high-voltage yemagetsi munda kana friction yekuchajisa kuti ikonzere zvinopesana pane hupfu hwenaironi uye chinhu chakavharwa, zvichiteerana. Iyo yakachajiswa poda yakashongedzwa inokwezvwa nechinhu chakaputirwa chakapesana, uye mushure mekunyunguduka nekudzikamisa, kupfekedza naironi inowanikwa. Kana iyo yekupfekedza ukobvu inodiwa isingapfuure 200 microns uye substrate isiri-yakakandwa simbi kana porous, hapana kupisa kunodiwa pakupfapfaidza kunotonhora. Kuti ufukidze hupfu hune ukobvu hunodiwa hunodarika 200 microns kana substrates nesimbi yakakandwa kana zvinhu zvine porous, iyo substrate inoda kudziyisa kusvika 250 ° C isati yapfapfaidza, iyo inodaidzwa kunzi kupisa kupfapfaidza.

Kupfapfaidza kutonhora kunoda zvidimbu zvehupfu zvenaironi kuti zvive nehupamhi hunosvika 20-50 microns. Dzimwe nguva, mhute yemvura inogona kupfapfaidzwa muhupfu kuti iwedzere kugona kwayo kutakura macheji uye kuderedza hurema hunokonzerwa nekurasikirwa kwehupfu usati wabika. Kupfapfaidza kupisa kunoda hupfu hwenaironi kuti huve nehupamhi hunosvika 100 microns. Zvimedu zvakakora zvinogona kukonzera kukora, asi zvakanyanyisa zvimedu zvinogona kukanganisa hupfu hwekunamatira. Munguva inopisa yekupfapfaidza, iyo substrate tembiricha inoderera nguva dzose, zvichiita kuti zviome kudzora ukobvu, asi kupfekedza hakuzobudisi hupfu kurasikirwa.

Iyo electrostatic spraying process ine yakafara siyana sarudzo dzekusarudza workpiece saizi, kunyanya kune workpieces ane ukobvu hwakasiyana, kuve nechokwadi chakafanana ukobvu. Kana workpiece isina kuvharwa zvachose kana ine chimiro chakaoma chisingagoni kunyudzwa mu fluidized bed, iyo electrostatic spraying process ine zvakanakira. Kupisa kwepamusoro-kupisa, kupfeka-resistant adhesive tepi inogona kushandiswa kuchengetedza kwenguva pfupi zvikamu zvisina kuvharwa. Kazhinji, kupfapfaidza kwemagetsi kunokwanisa kuwana jira rakatetepa, senge pakati pe150 microns uye 250 microns. Pamusoro pezvo, iyo naironi yakawanikwa neelectrostatic kutonhora yekupfapfaidza ine tembiricha yekunyungudika yakaderera, kazhinji inotenderedza 210-230 ° C kwemaminetsi mashanu-5, kusimba kwakanaka, uye kuderera kwekupisa kwekupisa. Kunamatira kune simbi kuri nani pane mamwe maitiro.
