Cov hlau xuab zeb nrog SAE tus qauv qhia

Kev Piav Qhia Luv:

Junda Steel Grit yog ua los ntawm kev sib tsoo cov hlau txhaj rau cov khoom me me uas tom qab ntawd tempered rau qhov nyuaj sib txawv rau kev siv sib txawv, tshuaj xyuas los ntawm qhov loj me raws li SAE Standard specification.

Junda Steel grit yog ib yam khoom siv uas siv ntau rau kev ua cov hlau ua haujlwm. Cov hlau grit muaj cov qauv nruj thiab qhov loj me sib npaug. Kev kho cov hlau grit steel shot rau saum npoo ntawm txhua cov hlau ua haujlwm tuaj yeem ua rau muaj kev nyuaj siab ntawm cov hlau ua haujlwm thiab txhim kho kev tiv thaiv kev qaug zog ntawm cov hlau ua haujlwm.

Kev siv cov hlau grit steel shot ua cov hlau ua haujlwm nto, nrog rau cov yam ntxwv ntawm kev ntxuav ceev ceev, muaj qhov rov qab zoo, ces kaum sab hauv thiab cov duab nyuaj ntawm cov haujlwm tuaj yeem ua npuas dej ntxuav sai, ua kom lub sijhawm kho qhov chaw luv dua, txhim kho kev ua haujlwm zoo, yog cov khoom siv kho qhov chaw zoo.

Cov Cim Npe Khoom

Junda Steel grit ntawm ntau yam hardness

1.GP steel grit: Cov abrasive no, thaum tshiab ua, yog taw tes thiab ribbed, thiab nws cov npoo thiab ces kaum sai sai puag ncig thaum siv. Nws yog tshwj xeeb tshaj yog rau kev kho ua ntej ntawm cov hlau nto tshem tawm cov oxide.
2. GL grit: Txawm hais tias qhov nyuaj ntawm GL grit siab dua GP grit, nws tseem poob nws cov npoo thiab ces kaum thaum lub sijhawm xuab zeb thiab tshwj xeeb tshaj yog rau kev kho ua ntej ntawm kev tshem tawm cov nplai oxide ntawm qhov chaw hlau.
3.GH hlau xuab zeb: Hom hlau xuab zeb no muaj qhov nyuaj siab thiab yuav ib txwm tswj tau cov npoo thiab ces kaum hauv kev ua haujlwm xuab zeb, uas yog qhov tshwj xeeb tshaj yog rau kev tsim cov nto tsis tu ncua thiab cov plaub hau. Thaum GH hlau xuab zeb siv rau hauv kev siv tshuab tua peening, cov kev cai tsim kho yuav tsum tau xav txog ua ntej cov yam ntxwv ntawm tus nqi (xws li kev kho dov hauv lub tshuab dov txias). Cov hlau xuab zeb no feem ntau yog siv rau hauv cov khoom siv tua peening cua compressed.

Daim ntawv thov kev lag luam

Kev Ntxuav Cov Hlau Grit
Cov hlau txhaj thiab cov xuab zeb yog siv rau hauv kev ntxuav kom tshem tawm cov khoom xoob ntawm cov hlau. Hom kev ntxuav no yog ib txwm muaj nyob rau hauv kev lag luam tsheb (lub cav, lub taub hau lub tog raj kheej, thiab lwm yam).

Kev npaj nto ntawm cov hlau xuab zeb
Kev npaj nto yog ua ntau yam haujlwm suav nrog kev ntxuav thiab kev hloov kho lub cev ntawm ib qho chaw. Cov hlau txhaj thiab cov xuab zeb siv rau hauv cov txheej txheem npaj nto rau kev ntxuav cov hlau uas muaj cov nplai zeb, av qias neeg, xeb, lossis cov xim pleev xim thiab rau kev hloov kho lub cev ntawm cov hlau xws li tsim kom muaj qhov ntxhib rau kev siv xim thiab txheej txheej zoo dua. Cov hlau txhaj feem ntau siv rau hauv cov tshuab tua phom.

Kev txiav pob zeb hlau
Cov xuab zeb hlau siv rau kev txiav cov pob zeb tawv, xws li granite. Cov xuab zeb no siv rau hauv cov thav duab loj uas muaj ntau hniav uas txiav cov pob zeb granite ua tej daim nyias nyias.

Kev siv tshuab steel grit shot peening
Kev siv cov khoom siv shot peening yog kev siv cov khoom tawv tawv ntaus rau ntawm qhov chaw hlau. Cov kev cuam tshuam no ua rau muaj kev hloov pauv ntawm qhov chaw hlau tab sis kuj ua rau cov hlau ruaj khov dua. Cov khoom siv hauv daim ntawv thov no yog spherical es tsis yog angular. Qhov laj thawj yog tias cov spherical shots tiv taus qhov tawg uas tshwm sim los ntawm kev cuam tshuam.

Cov xuab zeb steel rau kev tua xuab zeb
Qhov zoo ntawm cov hlau carbon grit siv rau kev xuab zeb blasting lub cev feem cuam tshuam ncaj qha rau qhov zoo thiab tus nqi tag nrho hauv cov nqe lus ntawm kev ua haujlwm xuab zeb blasting, girder txheej, pleev xim, lub zog kinetic thiab kev siv abrasive. Nrog rau qhov kev tso tawm tshiab txheej tiv thaiv kev ua tau zoo (PSPC), muaj kev thov siab dua rau qhov zoo ntawm cov xuab zeb blasting. Yog li ntawd, qhov zoo ntawm cov hlau cam khwb cia grit yog qhov tseem ceeb heev hauv kev xuab zeb blasting.

Angular txhaj tshuaj rau lub thawv xuab zeb
Siv cov xuab zeb xuab zeb uas muaj cov hlau kheej kheej los tua rau ntawm lub thawv tom qab nws vuam. Ntxuav qhov sib txuas uas vuam thiab tib lub sijhawm ua rau lub thawv lub cev nto muaj qee qhov roughness thiab ua kom cov xim pleev xim tiv thaiv xeb ntau ntxiv, kom thiaj li ua haujlwm tau ntev ntawm cov nkoj, lub chassis, lub tsheb thauj khoom thiab cov tsheb ciav hlau. Peb cov nqi xuab zeb xuab zeb yog qhov tsim nyog.

Grit spherical rau Cov khoom siv hluav taws xob qus sandblasting
Cov khoom siv hluav taws xob qus muaj qhov kev thov tshwj xeeb rau qhov roughness thiab kev huv ntawm qhov kev kho qhov chaw. Tom qab kev kho qhov chaw ntawm cov hlau angular grit, lawv yuav tsum tau hloov pauv huab cua sab nraum zoov ntev. Yog li ntawd, cov xuab zeb spherical grit rau qhov chaw yog qhov tseem ceeb heev.
