Kupfapfaidza maitiro uye zvinodiwa zvejeniral uye art powder coatings

Iyo inonzi Powder coating ndiko kushandiswa kwemusimboti wemunda wemagetsi wepamusoro voltage electrostatic corona. Yakabatanidzwa kune yakakwirira-voltage anode simbi deflector muyero pamusoro pfuti musoro, kupfapfaidza workpiece pasi kuumbwa zvakanaka, kuitira kuti paumbwe yakasimba static magetsi munda pakati pfuti uye workpiece. Kana iyo yakamanikidzwa mhepo semutakuri gasi, dhiramu re kupfeka hupfu nekuda kwehupfu yakatumira pollen chubhu kuti ipfapfaidze pfuti deflector tsvimbo, gwara tsvimbo yakabatana necorona discharge inogadzirwa ne-high-voltage anode, padhuze nedense negative charge, hupfu kuita chaji isina kunaka, ndokupinda musimba remunda wemagetsi. yenzvimbo yemagetsi yemagetsi mune huviri basa remagetsi akamira uye gasi rinotakura, hupfu hwakananga kunzvimbo yepasi pevhu kuti iite yunifomu ukobvu hwehupfu, uyezve kupisa kwekupisa kunoshandurwa kuita kukoira kwakasimba.
Coating application process:
Pretreatment – ​​kuyanika kubvisa mvura – kupfapfaidza – Tarisa – kubika – cheki – Kwapera

Coating application chinodiwa

Kupfapfaidza zvinodikanwa zvejeniral mhando poda coatings

1. Hunhu hwekuputira hupfu hunogona kupa kutamba kwakazara kuti uwedzere hupenyu hwekuputira kutyora pendi pendi kutanga kusati kwaitwa kurapwa.
2. pfapfaidzo, yakapendwa kuti inyatsodzika pasi kuitira kuti iwedzere kushanda kwehupfu hwekuputira.
3. iyo yakakura pamusoro pekuremara kupendwa, yakavharwa scratch conductive putty, kuitira kuti ive nechokwadi chekuumbwa kwejasi uye yakatsetseka.
4. Pfapfaidza kudiwa kwekurapa kupisa, kurapa mamiriro ehupfu zvigadzirwa zvehunyanzvi zviratidzo asi zvinofanirwa kuvimbiswa zvizere tembiricha yekurapa nenguva, kudzivirira kurapwa kunokonzerwa nekusakwana kunaka kwetsaona.
5. pakarepo kuputira guruva mushure mekuongororwa, kana chirema chikaonekwa chinofanirwa kugadziriswa nekukurumidza, mushure mekurapa chirema chaonekwa, chiyero chayo chinongoperera pasina kukanganisa kushongedza kwependi kunogona kushandiswa kugadzirisa zvakafanana. ruvara upfu ane acetone diluted, kana siyana kukanganisa pamusoro pemhando, kushandisa sandpaper, ipapo pfapfaidza kamwe kana kushandisa pendi remover kubvisa unhani, uye ipapo re-Suona upfu.
6. kudzoreredzwa kwehupfu hunofanirwa kusefa kubvisa marara mushure mechimwe chikamu chemusanganiswa wehupfu hutsva.
7. yehupfu dhiramu, kamuri yeupfu uye hurongwa hwekudzoreredza hunofanirwa kudzivirira kusvibiswa kwehupfu hwakasiyana, saka pese paunoshandura ruvara runofanira kucheneswa.

Pfapfaidza zvinodiwa kune art mhando poda coatings

Art powder ine yakanaka, yakasimba yechitatu dimension, uye yekushongedza mhedzisiro yekubatwa chibharo, asi yayo yakasimba yekuvaka maitiro.

1. kupukuta mhepo yekupinza mhepo haifaniri kunge yakakura zvikuru, geniral kudzora mu 0.5-1.5kg/cm2 zvakanaka. Dzvinyiriro inogona kukonzera kujeka kwepateni kushomeka kana kuve negomba. Electrostatic voltage haifanirwe kunge yakanyanya kukwirira, iyo general kutonga kwekutenderera 60-70Kv. Iyo voltage yakakwira zvakanyanya, inoita kuti hupfu hwakanamirwa kune pamusoro kuitika kweiyo rebound phenomenon Ma Hang. Kuenzanisa varombo nezvimwe zvirema.
2. kutorwa kuve nechokwadi kuti ukobvu hwejasi, jenaral kudzora kunogona kungobatsira pakuumbwa kweakakosha mapatani uye pateni pakati pe70-100μm, kupfekedza mutete pateni haisi pachena, asi iyo pateni zvakare idiki, uye ichaita Iyo gomba rakafumurwa pakupera
3. kurapa kunofanirwa kubikwa zvinoenderana neyakatsanangurwa tembiricha uye nguva. Kana tembiricha yakanyanya kuderera nguva ipfupi kuchaita kuti upfu usaite muitiro wemichina zvinhu zvakare wakaramba zvakanyanya, nepo kurapa hakuna kukwana. Pamusoro pezvo, nekuda kwechimiro chakakosha cheiyo art pateni yekugadzira poda, yobva yapfapfaidzwa nehupfu yakadzokororwa, maitiro ayo achange ari madiki kana asina kukosha shanduko inoitika, iri gene.rally yakakurudzira kuti kudzokororwa kweiyo art poda poda Usashandise. Kushandisa zvakare kunoenderana nekuyedzwa. Ona kubva pamusoro kunyange zvazvo zvakanyanya kuomarara zvinodiwa zvekuvaka, zvinotendwa kuti iyo yekupfekedza maitiro zviri nani kubata pamusoro apa zvinhu, ichaita kugutsikana kunodiwa.
