Koj puas paub sandblasting? –Cov lus qhia luv luv ntawm sandblasting 

Sandblasting tseem hu ua abrasive blasting, yog qhov ua ntawm kev ua kom zoo heev ntawm cov khoom siv abrasive ntawm qhov nrawm mus rau qhov chaw kom huv si lossis etch nws. Nws yog txheej txheem txheej txheej saum npoo uas suav nrog kev siv lub tshuab siv hluav taws xob (cua compressor) nrog rau lub tshuab sandblasting los tsuag cov khoom abrasive nyob rau hauv siab tiv thaiv qhov chaw. Nws yog hu ua "sandblasting" vim hais tias nws blasts nto nrog cov xuab zeb. Thaum cov xuab zeb hais tawm ntawm qhov chaw, lawv tsim ib qho smoother thiab ntau dua kev ntxhib los mos.

Kev siv Sandblasting

Sandblasting yog ib txoj hauv kev zoo tshaj plaws los ntxuav thiab npaj qhov chaw. Woodworkers, machinists, auto mechanics, thiab ntau dua tuaj yeem siv sandblasting hauv lawv txoj haujlwm, tshwj xeeb tshaj yog thaum lawv nkag siab txog ntau txoj hauv kev siv sandblasting.

1. Tshem tawm xeb thiab corrosion:Kev siv tshaj plaws ntawm kev tshaj tawm thiab xuab zeb blasting yog tshem tawm xeb thiab corrosion. Sandblasters tuaj yeem siv los tshem tawm cov xim, xeb, thiab lwm yam pa phem ntawm lub tsheb, tsev, tshuab, thiab yuav luag txhua qhov chaw.

2. NtoKev kho mob ua ntej:Sandblasting thiab xov xwm blasting yog ib txoj hauv kev zoo kom tau txais qhov chaw npaj rau xim lossis txheej. Nyob rau hauv lub ntiaj teb automotive nws yog txoj kev nyiam tshaj tawm tshaj tawm lub chassis ua ntejhmoov txheejnws. Cov xov xwm nruj dua li aluminium oxide tawm hauv qhov profile uas ua tau pab cov hmoov txheej ua kom zoo dua. Qhov no yog vim li cas feem ntau cov hmoov coaters nyiam cov khoom yuav tsum tau tshaj tawm blasted ua ntej txheej.

3. Kev kho cov khoom qub:Kev kho dua tshiab thiab tu txhua qhov txav mus los xws li tsheb, maus taus, cov cuab yeej siv hluav taws xob, thiab lwm yam, cov npoj yaig tshem tawm cov kev ntxhov siab qaug zog thiab txuas ntxiv lub neej kev pab cuam.

4. Tsim Kev Cai Textures thiab Artwork: Rau qee lub hom phiaj tshwj xeeb ua haujlwm, sandblasting tuaj yeem ua tiav qhov sib txawv los yog matt. Xws li polishing ntawm stainless hlau ua hauj lwm tej daim thiab yas, polishing ntawm jade, matting ntawm saum npoo ntawm cov rooj tog ntoo, cov qauv ntawm cov iav frosted, thiab texturing ntawm daim ntaub, thiab lwm yam. 

5. Smoothing ntxhib Casting thiab npoo:Qee zaum kev tshaj tawm blasting tuaj yeem ua tau du lossis ib nrab polishing ntawm qhov chaw uas yog qhov ntxhib me ntsis. Yog hais tias koj muaj ib tug ntxhib casting nrog ntse los yog irregular npoo koj siv tau ib tug xov xwm blaster nrog crushed iav kom du nto los yog soften ib tug ntse ntug.

Yuav ua li cas Sandblasting yog ua

Kev teeb tsa sandblasting feem ntau muaj peb yam tseem ceeb:

·Sandblasting tshuab

·Abrasives

·Blast nozzle

Sandblasting tshuab siv compressed cua ua lub zog los tsim high-speed dav hlau beams rau tshuaj tsuag cov ntaub ntawv (steev blasting iav hlaws dai, dub corundum, dawb corundum, alumina, quartz xuab zeb, emery, hlau xuab zeb, tooj liab ore, hiav txwv xuab zeb) yog txau rau saum npoo. ntawm cov khoom ua haujlwm yuav tsum tau ua tiav ntawm kev kub ceev, uas hloov cov khoom siv hluav taws xob ntawm sab nrauv ntawm qhov chaw ua haujlwm. Vim muaj kev cuam tshuam thiab kev txiav txim siab ntawm cov abrasive ntawm qhov chaw ua haujlwm, qhov chaw ntawm cov khoom ua haujlwm tau txais qee qhov kev huv huv thiab sib txawv roughness. Cov khoom siv kho tshuab ntawm qhov chaw ntawm cov khoom ua haujlwm tau zoo tuaj.

Txawm hais tias lub npe, xuab zeb tsis yog cov khoom siv nkaus xwb uas tuaj yeem siv hauv "sandblasting" txheej txheem. Cov khoom sib txawv tuaj yeem siv tau nyob ntawm cov khoom siv uas lawv tau siv. Cov abrasives no tuaj yeem suav nrog:

·Hlau grit

·Coal slag

·Dej khov qhuav

·Walnut thiab txiv maj phaub plhaub

·Crushed iav

Cov iav kev nyab xeeb tsim nyog yuav tsum tau siv thaum lub sij hawm xuab zeb blasting txheej txheem. Cov khoom abrasive tuaj yeem ua rau lub qhov muag thiab tawv nqaij, thiab yog tias nqus tau, tuaj yeem ua rau silicosis. Txhua tus neeg ua haujlwm sandblasting yuav tsum hnav cov cuab yeej kev nyab xeeb kom raug.

Tsis tas li ntawd, blast nozzle kuj yog ib qho tseem ceeb ntawm cov khoom. Feem ntau muaj ob hom blast nozzles: ncaj bore thiabkev lag luam hom. Rau kev xaiv blast nozzle, koj tuaj yeem xa mus rau peb lwm tsab xov xwm ntawm"Plaub cov kauj ruam qhia koj yuav ua li cas xaiv cov blast nozzles".
