Cathode Electrophoretic Painting Kab
Txheej txheem cej luam
Electrophoretic txheej kab yog ib hom kev ua haujlwm txuas ntxiv rau txheej txheej, uas yog siv hauv tsheb, khoom siv hauv tsev, hluav taws xob, khoom siv hlau thiab lwm yam lag luam. Los ntawm cov txheej txheem electrophoretic, txheej txheej ntawm cov xim tsis sib xws, cov xim pleev xim tiv thaiv corrosion tuaj yeem tsim rau ntawm qhov chaw ua haujlwm los txhim kho qhov zoo thiab ua haujlwm ntawm cov khoom. Electrophoretic txheej kab muaj qhov zoo ntawm kev ua haujlwm siab, txheej txheej zoo thiab daim ntawv thov dav.
Kev sib xyaw
1. Fais fab mov: fais fab mov yog ib qho tseem ceeb ntawm electrophoretic txheej kab, uas muab high voltage yuav tsum tau rau electrophoresis thiab tswj cov uniformity thiab stability ntawm electrophoresis txheej txheem nyob rau tib lub sij hawm.
2. Paint tank: Xim lub tank yog qhov chaw tuav cov xim hauv cov kab electrophoretic, uas suav nrog anode tank thiab cathode tank. Lub tank anode yog nruab nrog cov ntawv anode rau kev sib cuag nrog cov khoom ua haujlwm, thiab lub tank cathode yog nruab nrog cov xim thiab cov twj tso kua mis los tswj kev ruaj ntseg thiab fluidity ntawm cov xim.
3. Suspension mechanism: Lub tshuab raug tshem tawm yog lub luag haujlwm rau kev qhia thiab ncua kev ua haujlwm ntawm ib kawg ntawm cov kab ntau lawm mus rau txheej txheej thiab tshem tawm cov workpieces ntawm lwm qhov kawg. Nws muaj cov cuab yeej ncua kev kawm ntawv, cov cuab yeej qhia thiab lub tshuab tsav.
4. Tsav tsheb: cov cuab yeej tsav tsheb yog lub luag haujlwm los tswj kev khiav ceev ntawm cov kab hluav taws xob electrophoretic los xyuas kom meej cov txheej txheem zoo ntawm cov khoom ua haujlwm. Nws suav nrog lub cev muaj zog, reducer thiab lwm yam khoom siv.
5. Txau cov cuab yeej: cov cuab yeej siv dej txau yog siv los ntxuav thiab dispersing nto ntawm workpiece los tiv thaiv cov xim txuam thiab thaiv.
6. Powder spraying device: Hauv qee qhov kev siv, cov khoom siv tshuaj tsuag hmoov yog siv los txau cov hmoov txheej rau ntawm qhov chaw ua haujlwm tom qab electrophoresis los ua kom muaj kev tiv thaiv corrosion zoo dua.
7. Tshuab ziab khaub ncaws: lub tshuab ziab khaub ncaws yog siv los ua kom qhuav cov coated workpiece los ua cov xim pleev xim zaj duab xis nrog ib qho hardness thiab gloss.
8. Kev soj ntsuam cov cuab yeej: cov cuab yeej saib xyuas yog siv los saib xyuas thiab tswj cov txheej txheem txheej txheem txheej hauv lub sijhawm tiag tiag los xyuas kom meej tias cov txheej txheem ua tau raws li qhov yuav tsum tau ua.
Khoom Qhia
Txoj Cai Ua Haujlwm
Electrophoretic txheej yog txheej txheem electrochemical, los ntawm kev siv ncaj qha tam sim no, cov xim pleev xim (feem ntau yog anions) tso rau ntawm qhov chaw ntawm qhov chaw ua haujlwm los tsim cov xim zoo nkauj. Cov txheej txheem tshwj xeeb yog raws li hauv qab no:
1. Lub workpiece yog tsau nyob rau hauv lub electrophoresis tank los ntawm lub fixture thiab kev cob cog rua rau qhov tsis zoo electrode (cathode), tsim ib tug nruam cathode pas dej ua ke.
2. Cov xim pleev xim tuaj rau hauv kev sib cuag nrog lub workpiece hauv hluav taws xob thiab txav mus rau qhov chaw ua haujlwm nyob rau hauv qhov kev txiav txim ntawm qhov tsis zoo.
3. Nyob rau hauv qhov kev txiav txim ntawm cov hluav taws xob, cov xim pleev xim yog adsorbed rau ntawm qhov chaw ntawm lub workpiece thiab tau txais cov tshuaj tiv thaiv los tsim cov xim pleev xim.
4. Cov txheej txheem kho ntawm cov xim zaj duab xis yog ua tiav los ntawm kev ua kom sov lossis ultraviolet irradiation, thiab lwm yam.
5. Lub workpiece tom qab pleev xim yog muab tso rau hauv lub tshuab ziab khaub ncaws kom qhuav.
Qhov zoo
1. Kev ua haujlwm siab tiv thaiv corrosion: cathodic electrophoresis txheej muaj kev tiv thaiv corrosion zoo heev thiab tuaj yeem muab kev tiv thaiv corrosion mus ntev.
2. Kev ua haujlwm siab: cathodic electrophoresis txheej kab siv cov kab sib dhos ua haujlwm nrog kev ua haujlwm siab, uas tuaj yeem ua kom muaj peev xwm ntau lawm.
3. Cov txheej txheem zoo: Txij li txheej txheej txheej txheej raug kaw, txheej txheej yog ib yam thiab tsis muaj impurities, muab cov txiaj ntsig zoo txheej txheej.
4. Kev tiv thaiv ib puag ncig: cathodic electrophoresis txheej txheej txheem tsis muaj cov organic hnyav emission, uas yog qhov zoo rau kev tiv thaiv ib puag ncig.
5. Yooj yim los tswj: cov khoom siv txheej txheej yog tsim nyog, yooj yim los tswj thiab kho, ua kom lub neej ntev ntawm cov khoom siv.
6. Flexible: cov khoom siv txheej txheej tuaj yeem hloov kho raws li qhov xav tau ntawm cov khoom sib txawv kom paub txog kev tsim khoom.
