Sand blasting yog nruj me ntsis ib yam ntawm cov tawv nqaij zoo nkauj, uas tau muab faib ua concave thiab convex teebmeem. Lub sandblasting ntawm tes pwm kuj yog siv los ntawm compressed cua los tsim ib lub dav hlau ceev ceev los tsuag cov ntaub ntawv (tooj liab ore, quartz xuab zeb, carborundum, hlau xuab zeb, hiav txwv xuab zeb) rau saum npoo ntawm lub workpiece yuav tsum tau kho ntawm ib tug kev kub ceev, kom cov tsos los yog cov duab ntawm lub workpiece nto hloov. Vim muaj kev cuam tshuam thiab txiav cov nyhuv ntawm cov abrasive rau ntawm qhov chaw ntawm tes board workpiece, qhov saum npoo ntawm tes board workpiece tuaj yeem tau txais qee qhov kev huv thiab qhov sib txawv, thiab cov khoom siv ntawm tes board workpiece nto tuaj yeem txhim kho. . Yog li ntawd, kev qaug zog ua haujlwm ntawm tes board workpiece yog txhim kho, adhesion ntawm nws thiab txheej yog nce, lub durability ntawm txheej yog ncua, thiab nws kuj yog conducive rau lub leveling thiab kho kom zoo nkauj ntawm txheej.
Raws li cov txheej txheem sandblasting sib txawv, muaj plaub txoj kev faib tawm:
1. Siab blasting thiab suction blasting
2. Qhuav xuab zeb blasting thiab kua xuab zeb blasting
3. Qhib xuab zeb blasting thiab lub thawv (chav) xuab zeb blasting
4. Kev ceev xuab zeb blasting thiab tsis siv neeg xuab zeb blasting
Daim ntawv thov ntawm Sand Blasting rau Pwm Handboard
1. Cov xuab zeb blasting tuaj yeem tshem tawm tag nrho cov av ntawm qhov chaw ua haujlwm, xws li xeb nplai, thiab tsim cov qauv tseem ceeb heev (feem ntau hu ua ntxhib nto) ntawm qhov chaw ua haujlwm. Tsis tas li ntawd, nws tuaj yeem ua tiav qib sib txawv ntawm roughness los ntawm kev hloov cov abrasives ntawm ntau qhov ntau thiab tsawg. Lub workpiece yuav tsum tau sandblasted ua ntej txheej thiab sib txuas. Lub zog sib txuas ntawm tes phaj workpiece nrog cov txheej thiab cov khoom siv plating tau zoo heev. Los yog cov khoom sib txuas tuaj yeem sib koom ua ke nrog cov khoom zoo dua qub.
2. Kev tu, polishing thiab sandblasting ntawm ntxhib nto ntawm castings thiab forgings thiab workpiece tom qab kev kho cua sov tuaj yeem ntxuav tag nrho cov av (xws li oxide daim tawv nqaij, roj stain thiab lwm yam residues) nyob rau saum npoo ntawm castings thiab forgings thiab workpiece tom qab. Kev kho cua sov, thiab polish lub workpiece nto los txhim kho qhov smoothness ntawm workpiece, thiaj li ua tiav lub luag hauj lwm ntawm beautification thiab kho kom zoo nkauj.
3. Burr tu thiab deg beautification sandblasting ntawm machined qhov chaw tuaj yeem ntxuav cov burrs me me ntawm qhov chaw ua haujlwm, ua kom lub ntsej muag ntawm qhov chaw ua haujlwm zoo dua, tshem tawm cov kev puas tsuaj ntawm burrs, thiab txhim kho qib ntawm cov khoom ua haujlwm.
4. Txhim kho cov khoom siv ntawm cov khoom tom qab sandblasting, cov khoom siv kho tshuab tuaj yeem tsim txawm thiab zoo concave convex nto ntawm qhov chaw, kom cov roj lubricating tuaj yeem khaws cia, yog li txhim kho cov txheej txheem lubricating, txo cov suab nrov thiab nce kev pabcuam. lub neej ntawm cov tshuab.
5. Polishing muaj nuj nqi Rau qee lub hom phiaj tshwj xeeb workpieces, sandblasting tuaj yeem ua tiav qhov sib txawv los yog matting ntawm lub siab nyiam.
