Mumunda we sheet metal processing, kurapwa kwepamusoro hakungokanganisa kutaridzika kwechigadzirwa, asi zvakare kunoenderana zvakananga nekugara kwayo, kushanda uye kukwikwidza kwemusika. Kunyangwe ichishandiswa kumidziyo yemaindasitiri, kugadzira mota, kana midziyo yemagetsi, maitiro epamusoro epamusoro ekurapa anogona kuvandudza zvakanyanya kunaka kwechigadzirwa uye kukosha kwakawedzerwa. Aya gumi anotevera matipi akakosha akagadzirirwa kukubatsira iwe kukwenenzvera kuyerera kwesheet simbi pamusoro pekurapa uye kubatsira kuwana yakanakisa mhedzisiro zvakanyanya.
Zano 1: Yakarurama pre-kurapa
Kusati kwatanga nzira ipi neipi yekurapa kwepamusoro, kunyatsogadziriswa kwepamusoro ndiyo hwaro hwekuona mhedzisiro yekurapa kunotevera.
Kubvisa pamusoro pemafuta, maokisi uye ngura ndiro basa rekutanga. Unogona kushandisa madhigirii ane hunyanzvi kana kubvisa ngura, akasanganiswa nekunyorova, kupfapfaidza kana kupukuta nemaoko.
Kusvibiswa kwakasindimara, kugaya michina (senge sandpaper, grinding vhiri, nezvimwewo) inogona kushandiswa.
Chenjerera paunenge uchishanda:dzora simba kuti udzivise kukuvadza nzvimbo yepasi, kunyanya kune dzakatetepa mapepa esimbi.
Mazano ekuvandudza: Shandisa otomatiki pretreatment midziyo (senge masisitimu ekupfapfaidza) kuve nechokwadi chekugadzirisa kushanda zvakanaka uye kuenderana, kunyanya mukugadzirwa kwakawanda.
Zano 2: Sarudza chakakodzera coating material
Mamiriro akasiyana ekushandisa ane zvakasiyana zvinodiwa kune zvekupfekedza zvinhu zvemashizha esimbi zvikamu:
Kunze kwezvakatipoteredza: Inokurudzirwa kushandisa coating ine yakakwira mamiriro ekunze, senge fluorocarbon coating kana acrylic coating.
Yakakwirira friction zvikamu: Polyurethane coating kana ceramic coating inosarudzwa kuwedzera kupfeka kuramba.
Panguva imwecheteyo, kutarisa kunofanirawo kubhadharwa kune kusungirirwa kwekuputira, iyo inogona kuvandudzwa neprimer. Kune akakosha mamiriro ekuda (senge antibacterial kana insulating nzvimbo), inoshanda machira anogona kutariswa.
Mazano:Hushamwari hwezvakatipoteredza uye yakaderera VOC (volatile organic compound) zvemukati zvekupfekedza zvinhu zviri kuita zvemusika, uye girinhi uye zvine hushamwari machira anogona kusarudzwa.
Zano rechitatu: Otimize kupfapfaidza maitiro parameters
Kupfapfaidza maitiro maparamendi anotarisa zvakananga kunaka uye kutaridzika kwejasi:
Pfaya chinhambwe chepfuti: Inofanirwa kuchengetedzwa pakati pe15-25 cm kudzivirira kusagika kana kukora zvimedu.
Kupfapfaidza kudzvinyirirwa: Zvinokurudzirwa kuva pakati pe 0.3-0.6 MPa kuona yunifomu atomization yepende.
Kupfapfaidza kumhanya uye kona: Kune maworkpieces ane maumbirwo akaomarara, gadzirisa kona yepfuti yekupfapfaidza kuti uve nechokwadi chekuvharika kwekupfeka kwakafanana pamapendero nemagrooves.
Mazano ekuvandudza:Ita sampuli yekupfekedza zviyedzo panguva yekusimbisa chikamu chekugadzirisa parameter zvigadziriso uye ive nechokwadi chekugadzikana mukugadzirwa kwakakura.
Zano 4: Shandisa electrostatic spraying tekinoroji
Electrostatic spraying yave sarudzo yekutanga yemazuva ano kurapwa kwepamusoro nekuda kwehupamhi hwekunamatira kwayo uye kufanana:
Mhedzisiro yepasi ndiyo kiyi yemhando yekupfapfaidza, uye hunyanzvi hwekudzikisa pasi hunofanirwa kushandiswa kuve nechokwadi chekugadzikana kwemagetsi.
Gadzirisa iyo electrostatic voltage zvinoenderana nekuoma kwepepa simbi, kazhinji inodzorwa pakati pe50-80 KV.
Kune dzakaoma workpieces ane mapofu maburi kana mukati makomba, maviri-pfuti system kana bhuku rinobatsira spraying rinogona kushandiswa kudzivirira nzvimbo dzisina kusimba dzekuputira kunokonzerwa nemagetsi ekudzivirira munda.
Zano 5: Phosphating kurapwa kunowedzera anti-corrosion performance
Phosphating kurapwa haingogone kuvandudza corrosion kuramba kweiyo substrate, asi zvakare inosimudzira kunamatira kweanotevera machira:
Kudzora tembiricha: Iyo yakakurudzirwa phosphating tembiricha yesimbi iri pakati pe50-70 ℃. Kunyanya kukwira kana kuderera zvakanyanya kunokanganisa kufanana kwefirimu rephosphating.
Nguva yekumisikidza: Kazhinji 3-10 maminetsi, anogadziriswa zvinoenderana nezvinhu uye maitiro ekuda.
Kusimudzira zano: Shandisa yakaderera-tembiricha phosphating tekinoroji kuderedza mashandisirwo esimba, uye sanganisa neyakagadzikana ine hushamwari phosphating mhinduro kudzikisa kudzvanywa kwemaindasitiri emarara emarara.
Zano 6: Tora iwo epakati mapoinzi e electroplating process
Electroplating inogona kupa yakanakisa yekushongedza uye yekudzivirira zvivakwa, asi inoda yakanyanya kunyatso kudzora maitiro:
Ikozvino density uye tembiricha inofanira kunyatsoenderana. Semuyenzaniso, kana uchipfuta, tembiricha inofanira kunge iri pakati pe20-30℃ uye density iripo inofanira kuchengetedzwa pa2-4 A/dm².
Iko kusungirirwa kwezvinowedzera mumhinduro ye electroplating kunofanirwa kutariswa nguva nenguva kuti ive nechokwadi chekutsiga uye kusimba kwejasi.
Cherechedza: Kuchenesa mushure me electroplating kwakakosha. Residual electroplating mhinduro inogona kukonzera fogging kana kuora pamusoro peiyo coating.
Zano 7: Anodizing (yakasarudzika yealuminium zvikamu)
Anodizing ndiyo musimboti muitiro wekuvandudza corrosion kuramba uye yekushongedza mhedzisiro yealuminium sheet simbi zvikamu:
Iyo magetsi inokurudzirwa kudzorwa pa 10-20 V, uye nguva yekugadzirisa inogadziriswa maererano nezvinodiwa (20-60 maminitsi).
Kudhaya uye kuisa chisimbiso mushure me oxidation matanho akakosha ekuwedzera iyo antioxidant kugona uye kusimba kwemavara.
Advanced tekinoroji: Shandisa micro-arc oxidation (MAO) tekinoroji kuti uwedzere kuvandudza kuoma uye kupfeka kuramba kweiyo oxide firimu.
Zano rechisere: Kukuya pamusoro uye kukwenenzvera kuti uvandudze mazvo
Kurapa kwepamusoro kwepamusoro hakuparadzaniswe kubva pakukuya nekupukuta:
Sarudzo yejecha: Kubva pakukora kuenda kune yakanaka, nhanho nhanho, semuenzaniso, tanga shandisa 320#, wozochinja kuenda ku800# kana yepamusoro mesh.
Consistent operation: Iyo nzira yekukuya inofanirwa kuenderana kudzivirira kuyambuka kunokanganisa chitarisiko.
Kune maworkpieces ane yakakwira gloss zvinodiwa, girazi polishing inogona kushandiswa, yakasanganiswa nekunamira paste kana chromium oxide paste kuvandudza maitiro.
Zano 9: Simbisa kuongororwa kwemhando uye kudzora maitiro
Kugadzikana kwemhando yekurapa kwepamusoro hakuparadzaniswe kubva pakuongorora uye kutonga:
Coating ukobvu geji: tarisa ukobvu hwekuputira.
Adhesion bvunzo: senge muchinjika-kucheka kana kudhonza-kubvisa bvunzo, kuona kana iyo coating yakasimba.
Muedzo wekupfapfaidza munyu: kuongorora kusadzivirirwa nekuora.
Mazano ekuvandudza: nekuunza otomatiki yekuyedza michina, ive nechokwadi chekubudirira kwekuyedzwa, uye kusanganisa kuongororwa kwedata kune chaiyo-nguva process optimization.
Zano 10: Kuenderera mberi nekudzidza uye hunyanzvi hwekuvandudza tekinoroji
Tekinoroji yekurapa yepamusoro iri kuchinja nezuva rega rega, uye kuchengetedza hutungamiriri hwetekinoroji kunoda:
Teerera kune mafambiro eindasitiri: bata yazvino maitiro ekuita nekutora chikamu mukuratidzira uye masemina.
Tekinoroji R&D investimendi: unza yakangwara michina uye zvinhu zvitsva zvine hushamwari kwezvakatipoteredza kuti uvandudze kushanda nesimba uye kuchengetedzwa kwezvakatipoteredza.
Semuyenzaniso, ari kubuda matekinoroji akadai nano coatings uye plasma pfapfaidzo ari kusimudzirwa zvishoma nezvishoma, kupa mamwe mikana nokuda munda kurapwa pamusoro.
