Yakatumirwa pa 2019-01-11Matatu ebhizinesi mamiriro, rimwe remitemo uye maviri maitiro ane hukama ndeanofambisa vagadziri vezvisungo, zvimedu uye zvine hukama zvitambi zvidiki kuti vafunge nezve kushandiswa kwe dip spin coating tekinoroji.
Kutanga, vagadziri vezvakatipoteredza vanoramba vachiisa pfungwa dzavo paplating.Chechipiri, nhamba uye vhoriyamu yezvishandiso inoda kushanda kwepamusoro-soro maererano nemunyu wekupfapfaidza, Kesternich chiyero uye inowirirana torque tension iri kuwedzera.Kuisa dip spin coating pamusoro pezinc plate yakatetepa kuti ivhare zinc imhinduro inoshanda uye inodhura.Munyu wekupfapfaidza mhedzisiro yebvunzo inogona kukwidziridzwa kubva kune yakajairwa maawa zana nemakumi maviri kusvika chiuru nemazana uchishandisa iyi nzira.Inodiwawo kune dzimwe nzira dzakawanda kubva pakuona kwezvakatipoteredza.Pakupedzisira, hydrogen embrittlement chinhu chinoenderera mberi, uye dip / spin yakaratidza kukwanisa kuderedza zvakanyanya kana kubvisa dambudziko iri.
Dip spin inzira iyo chigadzirwa chinoiswa mudengu remesh, yakanyudzwa mune coating solution uye yakarukwa kubvisa yakawandisa coating.Iyo tembiricha uye viscosity yekupfekedza, nguva yekunyudza, spin kutungamira uye velocities uye nzira yekurapa iri pakati pezvakasiyana zvinobvumira vashandisi kugadzirisa maitiro ekubika uye kuwana chaiyo, inodzokororwa mhedzisiro.
Zvakare zvinocherechedzwa kugona kwedip/spin kudzikisa mutengo wezvose zviri zviviri zvekuputira zvinhu uye kuraswa kwemarara.Izvi zvinokonzerwa neiyo tekinoroji's 98 pct kana mukuru paavhareji yekutamisa kushanda zvakanaka.
Dip spin masisitimu akadai seaya anogadzirwa neSpring Tools, Portage, Michigan, anonyanya kubatsira kune zvikamu zvidiki zvine mamwe makonditi pamwe neayo anogona kuputirwa muhuwandu pasina kunamatira kune mumwe nemumwe.Uye kunyangwe paine zvinosarudzika (mumwe mugadziri wefastener anogadziridza mabhaudhi ake akakura-saizi yekudhip/spin processing), optimum process performance inoitwa nezvikamu zvinosvika 10 inches kana kushoma kureba uye isingasviki maviri inches mudhayamita.
Nepo washer uye zvimwe zvikamu zvakafuratira zvakanyanya kuputirwa nehumwe hunyanzvi, dip / spin inokodzera kumatenga uye zvimwe zvisungo zvekuvaka, zvisungo, zvitubu, o-mhete, u-mabhoti, zvipikiri uye screws, mota mounts uye zvimwe zvakawanda zvishandiso zvinoshandiswa. ye mechanical finishing.
Dip spin tekinoroji inoenderana nemhando dzese dzakakura dzekupfeka dzinoshandiswa mukusimbisa kupedzisa;kunyanya, machira anobatanidza kupikisa kwakanyanya kumakemikari uye galvanic / bi-metallic corrosion neUV kugadzikana, anti-galling properties uye / kana anti-vibration maitiro.Mazhinji anozoenderanawo nemasealants, anonamira uye anokiya zvigamba uye angave akaoma kusvika pakubata kana apora.Mhando dzekupfeka dzakanangana dzinosanganisira fluorocarbons, zinc-rich, ceramic metallics (aluminium-based with organic or inorganic topcoats) uye masisitimu anofambiswa nemvura.
Dip spin process inosanganisa matanho matatu: 1) Kuchenesa uye pretreatment;2) Coatings application;uye 3) Kurapa.Vagadziri vefastener vanowanzo shandisa grit ye80- kusvika 100-mesh aruminiyamu oxide kubvisa maokisi uye zviyero zvekupisa kupisa.Micro-, yepakati- kana inorema-crystalline zinc phosphate ndiyo inofarirwa pretreatment painodiwa, kunyangwe paine akati wandei dip / spin coatings anogona kuiswa pamusoro pesimbi isina chinhu.
Mushure mekuoma, zvikamu zvinotakurwa muwaya-mesh lined basket.Kana kurodha kuri otomatiki, sisitimu inoendesa zvikamu kune huremu sikeri hopper ine pre-set batch huremu.Mushure mekurodha, zvikamu zvinotamirwa mukamuri yekudhibha / spin uye pane inotenderera inotenderera chikuva payakavharirwa panzvimbo.Chigadziko chekuputira, chakamisikidzwa pazasi, chinosimudzwa kuti inyise dengu rezvikamu mujira.
Kana nguva yekunyudza yakwana, chigaba chekuputira chinodonha kusvika padanho iro dengu richiri mumudziyo, asi pamusoro pemvura.Dengu rinobva raiswa centrifuged.
A common spin cycle angave one direction for 20 to 30 sec, a full brake, wozodzokera reverse spin kwenguva yakaenzana.Iyo braking chiito inodzoreredza mativi kuti anyatso bvisa machira kubva pakadzika.Kana dip/spin yapera, mudziyo wekuputira unodzikiswa zvakazara uye tswanda inodzokororwa, kuvhurwa nekubviswa.Re-loading inoitika uye maitiro anodzokororwa.
Coating material inoiswa mumudziyo wesimbi wopinzwa wobviswa nepamusuwo wepadivi.Kuchinja kwemavara kunoitwa mu10 kusvika 15 min nekungobvisa yekutanga yekubikira mudziyo uye tswanda uye kuitsiva nemitsva.Mabhanhire anochengeterwa mudhipi / spin mudziyo, iyo yakavharwa nesimbi kana polyethylene chivharo.Mesh mabhasikiti anocheneswa uchishandisa soak yakanyungudika kana grit blast kana mesh liner yega inogadziriswa muovheni inotsva.
Zvishongo zvishoma zvinoshandiswa mufastener kupedzisa mhepo yakaoma.Kune iyo 90 pct plus inoda kupisa, diki dip / spin mitsara inosanganisira batch oveni;midziyo yakakura inosanganisira ovheni yebhandi inotakurwa.Conveyor mabhandi akakura kune zvikamu.Zvikamu zvakaputirwa zvinotakurwa zvakananga pabhandi revheni uye zvinopararira nemaoko pamusoro pehupamhi.Kana kuti, dzinoburutswa patireyi inodedera inoisa zvikamu pamusoro pebhandi rehovhoni otomatiki.
Kurapa kutenderera kunobva pashanu kusvika ku30 min;tembiricha yepamusoro yesimbi i149 kusvika 316F.Chiteshi chekutonhodza mhepo chinomanikidza chinodzosa tembiricha yechigadzirwa kusvika pedyo neambient.
Dip spin midziyo inogadzirwa muhukuru hwakayerwa kugadzirisa zvinodiwa.Uko mabhechi echigadzirwa ari madiki uye akawanda shanduko yemavara anodiwa, diki system, ine dhayamita gumi-inch dhayamita, 750 lb/hr kugona uye kumhanya kwekutenderera kubva pazero kusvika 900 rpm ingakurudzirwa.Iri rudzi rwehurongwa huchagadzirisa kushanda kwemaoko, uko mushandisi anotakura dengu uye oshandisa dip uye spin zvikamu zvematenderedzwa achishandisa mavharuvhu emaoko kana chidimbu otomatiki uko kurodha / kurodha kuri manyorero, asi matenderedzwa anodzorwa nePLC.
Muchina wepakati, wakakodzera kuzvitoro zvakawanda zvebasa unoshandisa tswanda 16 inches mudhayamita ine vhoriyamu inoshandisika yeimwe cu ft. Kugona kunosvika 150 lbs.Iyi sisitimu yaiwanzo gadzira kusvika ku4,000 lbs/hr yechigadzirwa uye inomhanyisa kumhanya inosvika 450 rpm.
Iwo makuru ekugadzira fastener uye anopedzisa zvitoro zvebasa anowanzo kushandirwa zvakanyanya nesystem inoshandisa 24-inch diameter tswanda uye ine spin yekumhanya inosvika 400 rpm.
