Aluminium profiles hmoov txau txheej kab

Hmoov txheej siv lub hauv paus ntsiab lus ntawm electrostatic txau ntawm qhuav hmoov adsorption ntawm cov hlau txhuas profiles, tom qab 200 ℃ kub barbecue, cov hmoov kho rau hauv ib txheej ntawm li 60 microns tuab khoom ci txheej. Ua kom cov khoom nto du thiab txawm xim nrog muaj zog acid tsis kam, alkali tsis kam, cuam tshuam tsis kam, hnav tsis kam, tuaj yeem tiv taus cov hluav taws xob ultraviolet thiab acid nag yaig rau lub sijhawm ntev, tsis tshwm sim txheej chalking, fading, tev thiab lwm yam tshwm sim. Hmoov coated txhuas profiles muaj kev pab cuam lub neej ntawm 30 xyoo nyob rau hauv ib txwm tej yam kev mob. Nws txheej txheej hauv 5-10 xyoo los xyuas kom meej tias cov xim tsis ploj, tsis hloov xim, tsis tawg. Nws cov huab cua tsis kam thiab corrosion yog zoo dua li cov xim txhuas zoo sib xws.

Loading → Pretreatment → Moisture Drying → Cooling → Powder spraying (Reciprocator) → Powder curing ( cua kub ncig) → Cooling → Unloading

Cov txheej txheem ua ntej kev kho mob ncaj qha cuam tshuam rau qhov zoo ntawm cov hmoov txheej zaj duab xis, kev kho ua ntej tsis zoo, ua rau yooj yim rau tev tawm zaj duab xis, bubbling thiab lwm yam tshwm sim.

Rau cov ntawv hlau stamping qhov chaw tuaj yeem siv cov tshuaj pretreatment txoj kev. Feem ntau ntawm cov xeb los yog nto thicker workpiece, siv cov xuab zeb blasting, tua blasting thiab lwm yam txheej txheem los tshem tawm xeb, tab sis txhua yam descaling yuav tsum xyuas kom meej tias cov nto ntawm lub workpiece yog huv si thiab unscaled.

Raws li cov degree ntawm qhov tsis xws luag nyob rau hauv lub workpiece scraping conductive putty, tom qab ziab nrog sandpaper sib tsoo du, koj muaj peev xwm nqa tawm cov txheej txheem tom ntej.

Yog tias muaj qee qhov ntawm cov khoom ua haujlwm uas tsis tas yuav muaj txheej txheej, lawv tuaj yeem npog nrog cov nplaum tiv thaiv, thiab lwm yam, ua ntej preheating kom tsis txhob txau rau ntawm txheej.

Preheating feem ntau tsis tas yuav tsum tau. Yog hais tias yuav tsum tau ib tug tuab txheej, lub workpiece yuav preheated rau 100-160 ℃, uas yuav ua rau kom lub thickness ntawm txheej.

Electrostatic generator los ntawm rab phom muzzle ntawm rab koob electrode mus rau workpiece kev taw qhia ntawm qhov chaw tso tawm high-voltage electrostatic (tsis zoo), high-voltage electrostatic los ntawm rab phom muzzle ntawm cov hmoov thiab compressed cua sib tov nrog rau cov electrode nyob ib ncig ntawm. huab cua ionization (tsis zoo nqi). Lub workpiece los ntawm cov hangers los ntawm cov conveyor txuas hauv av (cov ncej hauv av), kom cov phom thiab cov khoom ua haujlwm los ua ib qho hluav taws xob nruab nrab ntawm cov hmoov hauv hluav taws xob hauv hluav taws xob thiab cov cua compressed hauv qab ob lub laub mus rau saum npoo ntawm lub workpiece, cia siab rau electrostatic attraction rau ntawm qhov chaw ntawm lub workpiece los tsim ib txheej ntawm txheej txheej.

Tom qab txau cov khoom ua haujlwm los ntawm cov saw hlau conveyor rau hauv 180 ~ 200 ℃ ci chav cua sov, thiab ua kom sov rau lub sijhawm sib xws, (15-20 feeb) kom cov melting, leveling, curing, thiaj li kom tau lub workpiece nto nyhuv peb. xav. (Cov hmoov sib txawv yog qhov sib txawv ntawm qhov kub thiab lub sijhawm ci). Qhov no yog qhov peb yuav tsum xyuam xim rau hauv cov txheej txheem kho.

Tom qab txheej txheej yog kho, tshem tawm cov kev tiv thaiv thiab txiav cov burrs.

Tom qab kho lub workpiece, lub ntsiab niaj hnub tshuaj xyuas ntawm cov tsos (txawm yog du thiab ci, nrog los yog tsis muaj hais, shrinkage thiab lwm yam tsis xws luag) thiab thickness (tswj nyob rau hauv 55 ~ 90μm). Rau qhov kuaj pom qhov tsis xws luag xws li to, pinhole, bruise, npuas, thiab lwm yam, lub workpiece yuav raug kho lossis rov ua dua.

Tom qab kev tshuaj xyuas, cov khoom tiav raug txheeb xyuas thiab muab tso rau hauv lub tsheb thauj mus los thiab lub thawv xa khoom, thiab sib cais los ntawm ib leeg los ntawm cov khoom siv mos mos xws li cov ntawv ua npuas dej thiab npuas zaj duab xis los tiv thaiv khawb thiab puas.
