Hom abrasives tuaj yeem muab faib ua ob pawg raws li cov khoom siv: non-metallic abrasives thiab hlau abrasives.
Non-metallic abrasives feem ntau muaj xws li tooj liab ore, quartz xuab zeb, dej xuab zeb, corundum, iav, thiab lwm yam. Vim lub siab crushing tus nqi ntawm non-metallic abrasives, ntau plua plav, muaj kuab paug loj thiab tsis tshua muaj efficiency, tsuas yog rau ob peb tug txuas ntxiv mus, feem ntau ntawm lawv tau maj mam hloov los ntawm cov hlau abrasives.
Hlau abrasives sawv cev rau cam khwb cia hlau txhaj tshuaj (high carbon thiab tsawg carbon), steel grit, hlau txhaj tshuaj, hlau grit, stainless hlau txhaj, hlau txiav txhaj tshuaj, bearing steel grit.
Hardness ntawm Hlau Abrasives
Cov kev xav tau hardness ntawm abrasive tuaj yeem txiav txim siab raws li lub xeev ntawm lub workpiece. Feem ntau hais lus, tus nqi hardness yuav tsum siab tshaj qhov hardness ntawm lub workpiece HRC3 ~ HRC10. Lub hardness ntawm abrasive cuam tshuam rau kev ceev ceev thiab cov nyhuv.
Thaum cov khoom abrasive cuam tshuam rau saum npoo ntawm qhov chaw ua haujlwm ntawm kev kub ceev, qhov cuam tshuam kinetic zog siv rau lawv los ntawm cov khoom siv, thaum lub sij hawm ntawm kev cuam tshuam, ib feem ntawm lub zog yog ib txwm noj nyob rau hauv lub deformation ntawm lub abrasive, uas tsis tuaj yeem hloov tag nrho. mus rau saum npoo ntawm qhov cuam tshuam workpiece, thiab tsis ua kom tiav cov txiaj ntsig zoo. Lub zog siv feem ntau txiav txim siab los ntawm hardness ntawm abrasive.
Qhov hu ua hardness txhais tau tias yog lub peev xwm los tiv thaiv deformation. Qhov siab dua qhov hardness, qhov ntau dua qhov kev tiv thaiv deformation, qhov ntau dua qhov feem pua ntawm lub zog hloov mus rau qhov chaw ntawm qhov chaw ua haujlwm, thiab qhov pom tseeb dua cov nyhuv tu.
Feem ntau, qhov zoo tshaj plaws hardness ntau yam ntawm abrasives yuav tsum yog nruab nrab, ib yam nkaus thiab nyuaj yog ib qho yooj yim rau tawg, heev mos yog yooj yim deform. Qee cov abrasives siab hardness (xws li cam khwb cia hlau txhaj tshuaj) tuaj yeem ntxuav tau sai lossis ntxiv dag zog, thiab tus nqi ntawm cov abrasive kuj qis, tab sis cov abrasives no tsis yooj yim thiab muaj kev noj ntau, uas tuaj yeem ua rau ntxov ntxov ntawm cov khoom hnav. cov cuab yeej txhaj tshuaj blasting thiab nce nqi kho; ntawm qhov tsis sib xws Yog, lwm cov khoom siv tawv tawv tsis tshua muaj kev noj qab haus huv thiab tus nqi qis, tab sis lawv muaj kev tu ncua ntev, kev tsim khoom tsawg, thiab kev siv lub sijhawm ua haujlwm tsis zoo.
Crushing Performance ntawm Hlau Abrasives
Lub crushing yam ntxwv ntawm lub abrasive yuav ncaj qha cuam tshuam rau tus nqi, txij nkawm nqi thiab tu nyhuv ntawm lub abrasive.
Vim qhov sib txawv ntawm cov tshuaj muaj pes tsawg leeg, cov txheej txheem tsim khoom thiab cov qauv metallographic, cov yam ntxwv qaug zog ntawm txhua tus abrasive sib txawv, uas txiav txim siab nws cov yam ntxwv sib txawv hauv cov khoom siv tua blasting.
Lub crushing ntawm abrasive txhais tau hais tias nyob rau hauv cov tshuaj tua blasting tu cov cuab yeej, abrasive hais yog pov tawm ntawm ib tug heev ceev thiab cuam tshuam rau saum npoo ntawm lub workpiece. Thaum cov haujlwm tu thiab ntxiv dag zog ua tiav, cov abrasive nws tus kheej tau noj los ntawm kev cuam tshuam thiab hnav cov khoom siv tib lub sijhawm. Los ntawm kev ncig mus tas li thiab rov cuam tshuam, los ntawm cov khoom loj mus rau cov khoom me me, los ntawm cov khoom me me mus rau cov khoom me me, thiab thaum kawg vim tias cov khoom me me dhau lawm (tsawg dua 0.2mm) yuav siv tau, lawv raug tshem tawm los ntawm kev txhaj tshuaj. cov khoom siv blasting thiab cov plua plav tshem tawm.
Lub crushing tus nqi ntawm cov abrasive kuj txiav txim siab npaum li cas ntawm cov tshiab ntse-pob tshab particles tsim nyob rau hauv lub lag luam. Lub kaum ntse ntse ua rau muaj kev tiv thaiv loj, uas ua rau tsis zoo ntawm cov khoom siv abrasives, uas ua rau khawb thiab puas rau cov khoom siv.
Yog li ntawd, qhov kev ua tau zoo ntawm cov abrasives yog qhov tseem ceeb rau kev ntsuas cov khoom zoo abrasives.
Abrasive Size Xaiv
Pa abrasive diameters li ntawm 0.3mm txog 2.8mm. Qhov loj dua ntawm abrasive hom, qhov nrawm dua qhov kev txhaj tshuaj blasting efficiency, tab sis qhov ntau dua qhov roughness ntawm qhov txhaj tshuaj blasting workpiece, qhov opposite yog qhov tseeb; Yog li ntawd, nws yog ib qho tseem ceeb tshwj xeeb los xaiv hom txhaj tshuaj blasting abrasive uas haum rau qhov loj ntawm lub workpiece.
Nco tseg
Rau kev pub khoom siv tshiab, ib qho abrasive tsis tuaj yeem siv, thiab qee qhov tuab thiab qhov zoo yuav tsum tau muab sib xyaw kom tau txais kev pabcuam zoo thiab kev tu kom zoo.
