Cov txheej txheem
Cov txheej txheem anodizing feem ntau muaj xws li txhuam matte ntuj xim, txhuam lub ntsej muag zoo nkauj xim, txhuam hniav ci ntsa iab, thiab matte txhuam dyeing (tuaj yeem dyed rau hauv ib qho xim series). Polished ci ntuj xim, polished matte ntuj xim
, Polished ci nto dyeing, polished matte dyed. Lub suab nrov thiab ci ntsa iab xim, suab nrov thiab pos huab xim, sandblasting dyeing. Cov hom plating saum toj no tuaj yeem siv rau ntawm cov khoom siv teeb pom kev zoo.
Aluminium profile ua ntws
1. Aluminium ingots: Ua ntej kev tsim khoom, raws li kev tsim cov txhuas ingots ntawm cov hlau sib txawv thiab cov txiaj ntsig sib txawv, cov khoom siv aluminium txaus, magnesium ingots, silicon ingots, tooj liab ingots thiab cov ntaub ntawv pab tau nruab.
2. Rauv loading: siv lub forklift thauj cov txhuas ingots, compound ingots, thiab pas nrig xaus rau hauv lub melting furnace.
3. Melting: Tom qab ntxiv cov khoom txaus nyob rau hauv lub cub tawg, siv cov nkev roj kom sov li 700-730 ℃, thiab tom qab ntawd cov txhuas ingot yuav yaj mus rau hauv lub xeev cov kua.
4. Refining: ntxiv ntau yam paving pab tshem tawm impurities hauv cov dej txhuas.
5. Muab cov txhuas molten: Tshem tawm lub ntsaws ntawm qhov chaw nres nkoj hauv qab ntawm lub cub tawg, thiab tso cov molten aluminium.
6. Casting: Cov dej txias yog qhib tom qab 25 ~ 35 vib nas this tom qab molten aluminium yog ntim nrog shunt phaj. Lub casting ceev yog 70 ~ 80% ntawm qhov ib txwm ceev, thiab qhov ceev yog nce mus rau qhov qub ceev tom qab poob los ntawm 40-50mm.
7. Homogenization: aluminium pas nrig yog raug rau kev kho mob homogenization theem nrab.
8. Pom bar: Tshem tawm qhov tsis sib xws ntawm lub hauv ntej thiab nram qab kawg ntawm aluminium bar.
9. Nyob rau hauv lub warehouse: cov txhuas rods yog bundled rau hauv lub warehouse thiab muab tso rau.
Sandblasting + txheej txheem kev kho oxidation:
Tom qab kev lag luam aluminium profile yog extruded, yuav pom tseeb stretch marks ntawm qhov chaw, thiab nto muaj micropores loj thiab kuj ntxhib. Nws yuav tsum tau sandblasted. Kev siv emery hauv cov txheej txheem sandblasting
Qhov kev cuam tshuam yuav ua rau muaj kev hloov pauv ntawm cov qauv ntawm cov txhuas profile. Nrog rau cov txheej txheem yas deformation, cov khoom siv lead ua yuav plam, ua rau muaj qhov nce ntawm qhov ntom ntawm qhov tsis sib xws hauv cov subgrain thiab qhov profile nto ua flatter.
plam.
Kev kho deg ntawm kev lag luam aluminium profiles mus dhau cov kauj ruam hauv qab no:
①: Kev kho deg sandblasting;
