Pre - kurapwa bhuku rakareruka maitiro uye otomatiki pre - kurapwa maitiro, iwo ekupedzisira akakamurwa kuita otomatiki spray uye otomatiki dip pfapfaidza maitiro maviri.Iyo workpiece inofanirwa kugadziriswa pamusoro kubvisa mafuta uye ngura isati yamwaya.Muchikamu chino panoshandiswa mvura yakawanda, kunyanya kubvisa ngura, degreasing agent, tafura yekugadzirisa, phosphating agent uye zvichingodaro.
Muchikamu chekugadzirisa kana musangano pamberi pemutsara wekugadzira pendi, kutarisisa kunofanirwa kubhadharwa pakugadzwa kwekutenga kunodiwa, kutakura, kuchengetedza uye kushandiswa kweasidhi yakasimba uye alkali system, kupa vashandi zvipfeko zvinodzivirira, zvipfeko zvakachengeteka uye zvakavimbika, kubata, kugadzirwa kwemidziyo, pamwe nekuvandudzwa kwematanho ekurapa kwekukurumidzira uye matanho ekudzikinura kana njodzi.Chechipiri, muchikamu chepretreatment chekugadzira mutsara wekugadzira, nekuda kwekuvapo kweimwe huwandu hwemarara gasi, tsvina yemvura uye zvimwe zvinhu zvitatu zvinoraswa, saka maererano nematanho ekudzivirira kwezvakatipoteredza, zvinodikanwa kugadzirisa kubuda kwemhepo, kubuda kwemvura uye. midziyo mitatu yekurapa tsvina.
Hunhu hweiyo pre-yakagadziriswa workpiece inofanirwa kuve yakasiyana nekuda kweyakasiyana pretreatment mhinduro uye coating yekugadzira mutsara maitiro.Kugadziriswa kurinani kweiyo workpiece, mafuta epamusoro, ngura yekuita, kuitira kudzivirira nguva pfupi kuti iite ngura zvakare, kazhinji inofanirwa kunge iri mu pretreatment mushure memaitiro akati wandei, phosphating kana passivation kurapwa: usati wapfapfaidza hupfu, zvakare inofanira kunge iine phosphating workpiece. pakuomeswa, kuunyoro hwayo hwepamusoro.Diki batch single kugadzirwa, kazhinji kushandisa yakasikwa mhepo kuomesa, kuomeswa nezuva, kuomesa mhepo.Uye kune huwandu hukuru hwebasa rekuyerera, kazhinji tora yakadzika tembiricha kuomesa, uchishandisa oveni kana kuomesa mugwagwa.
Kupfapfaidza hupfu coating sangano kugadzirwa
Kune diki batch workpiece, manyorero ekupukuta guruva rinowanzo kutorwa, uye kune hombe batch workpiece, manual kana otomatiki guruva mudziyo unowanzo shandiswa.Ingave yemanyorero kana otomatiki guruva, kutonga kwemhando kwakakosha.Kuti ave nechokwadi chokuti spraying workpiece upfu yunifomu, inowirirana ukobvu, kudzivirira mutete pfapfaidzo, leakage pfapfaidzo, pukuta uye zvimwe zvikanganiso.
Coating yekugadzira mutsara mukuita, asi zvakare unofanirwa kuterera kune hoko chikamu cheworkpiece, usati wapinda mukurapa, unofanirwa kunamatira kune hupfu hwayo kusvika painoputika, kudzivirira yakawandisa poda kurapa hoko, imwe yekurapa bvisa yasara hupfu. kusati kwaoma, kunofanira kuva nenguva yekubvisa hoko kune yakaomeswa upfu firimu, conductive kuve nechokwadi kuti chirauro chakanaka, uye nhamba yezvigadzirwa zvehupfu.
Kugadzira manejimendi yekurapa maitiro mu coating line
Maitiro aya anofanira kuteerera: akapfapfaidza workpiece, kana iri batch diki kugadzirwa chete, kupinda muchoto kurapa asati kuteerera kudzivirira kudonha upfu, akadai upfu vachikwiza chiitiko, inofanira kuva nenguva pfapfaidzo upfu.Pakubika, kuomarara maitiro uye tembiricha, kutonga nguva, teerera kudzivirira kusiyana kwemavara, pamusoro pekubika kana nguva ipfupi inokonzerwa nekusakwana kurapa.
Kune yakawanda otomatiki kuendeswa kweworkpiece, mumugwagwa wekuomesa pamberi zvakare nyatsoongorora kana kuvuza pfapfaidzo, pfapfaidzo yakaonda kana yemunharaunda upfu chiitiko, senge yakawanikwa isina kukodzera zvikamu, inofanira kuvharwa kudzivirira kupinda munzira yekuomesa, sezvinobvira. bvisa pfapfaidzo.Kana workpiece yega isina kukodzera nekuda kwekupfapfaidza yakatetepa, inogona kupfapfaidzwa zvakare nekusimbiswa zvakare mushure mekurapa.
