Lub hauv paus ntsiab lus ntawm Vacuum Aluminium Plating Tshuab rau Hluav Taws Xob Hluav Taws Xob Tube Electroplating

2.1 Lub tshuab nqus tsev vacuum

Lub tshuab nqus tsev aluminium plating siv yog tsim los ntawm lub tshuab winding, evaporation system, lub tshuab nqus tsev, thiab tswj qhov system. Vim tias qhov xav tau ntawm lub tshuab nqus tsev nyob rau hauv ob qho tib si txheej thiab winding chambers thaum lub sij hawm txhuas plating, lub tshuab nqus tsev yog siv los ua kom tiav qib nqus tsev vacuum nyob rau hauv lub txheej thiab winding chamber ua ntej evaporation. Raws li pom nyob rau hauv daim duab 1, daim duab schematic ntawm lub tshuab nqus tsev aluminium plating lub tshuab nqus tsev yog qhia. Txhawm rau kom ua tiav kev siv txhua lub tshuab nqus tsev, lub twj tso kua mis swb yog thawj zaug qhib rau lub tshuab nqus tsev ua ntej lub tshuab nqus tsev ua haujlwm qis, mus txog qhov nruab nrab lub tshuab nqus tsev ua haujlwm ntawm cov twj tso kua mis thib ob. Lub tshuab nqus tsev pib qhib, thiab tom qab ntawd thaum lub tshuab nqus tsev nqus mus txog hauv qab 100-10-1Pa, lub siab valve thiab pem hauv ntej valve ntawm lub twj tso kua mis tau qhib, tso cai rau lub twj tso kua mis txuas ntxiv nqus lub tshuab nqus tsev, Tom qab lub tshuab nqus tsev kawm tiav ncav cuag 10-1-10-2Pa, lub siab valve thiab pem hauv ntej valve ntawm diffusion twj tso kua mis qhib. Thaum lub tshuab nqus tsev kawm ntawv ruaj khov ntawm 10-1-10-2Pa, raws li cov yam ntxwv ntawm cov khoom siv cua tshuab, siv cov dej emulsion PET zaj duab xis, thiab lub tshuab nqus tsev kawm ntawv yuav tsum qis dua 10-2Pa. PET / PE zaj duab xis sib xyaw nrog cov roj nplaum yog siv, thiab lub tshuab nqus tsev nqus tau qis dua me ntsis, thiab nws tuaj yeem qhib tom qab 10-1Pa. Thaum hloov cov yob rau lwm qhov txhuas plating, tsis txhob tua cov roj twj tso kua mis thiab cov roj diffusion twj tso kua mis kom ntseeg tau tias cov roj vapor hauv lub twj tso kua mis yog nyob rau hauv lub xeev evaporative, txo lub sij hawm siv rau preheating lub twj tso kua mis lub cev.

1. Khaws lub twj tso kua mis; 2. Diffusion twj tso kua mis; 3. Rough extraction valve; 4. Txheej txheej; 5. chav cua txias; 6. Inflation valve; 7. Siab valve; 8. Booster twj tso kua mis; 9. Pem hauv ntej theem valve; 10. Lub twj tso kua mis; 11. Khaws lub twj tso kua mis; 12. Coarse extraction valve; 13. Pem hauv ntej theem valve; 14. Lub twj tso kua mis; 15. Swb valve twj tso kua mis

Lub hauv paus ntsiab lus ntawm lub tshuab nqus tsev chamber yog hais tias nyob rau hauv ib tug tej yam lub siab nqus tsev vacuum, lub rhuab aluminium hlau melts rau hauv kua txhuas. Cov kua aluminium sai sai evaporates rau hauv aluminium vapor nyob rau hauv lub tshuab nqus tsev siab, thiab aluminium vapor solidifies rau hauv ib txheej nyias nyias ntawm cov zaj duab xis thaum nws ntsib cov yeeb yaj kiab txias. Cov txheej txheem no yog cov txheej txheem ntawm lub cev uas ua tiav cov txheej txheem ntawm cov txheej txheej nyias thiab cov txheej txheem txhuas ntawm cov yeeb yaj kiab nyias los ntawm kev hloov pauv ntawm txhuas daim ntawv (khoom → kua → roj → khoom).

Raws li kev paub dhau los, hais txog qhov loj me me thiab xav tau kev cuam tshuam ntawm cov iav hlaws hom cov ntaub ntawv cuam tshuam, thaum lub txhuas txheej ntawm cov hlaws dav dav ncav cuag 150-200A, nws lub zog sib txuas nrog cov iav hlaws yog qhov muaj zog, thiab Tom qab kev sim, qhov kev cuam tshuam ntawm kev ua haujlwm yog ntau dua 95 feem pua. Raws li cov txheej txheem tsim khoom, nws feem ntau tsim nyog rau cov txheej txheem txhuas ntawm cov khoom siv hluav taws xob microbead kom nyob nruab nrab ntawm 150 thiab 400A.
