Daxalka birta ayaa meel walba yaal, mar walba

Si looga hortago daxalka birta, habka ugu caansan waa in la isticmaalo dahaarka si loo ilaaliyo dusha sare ee alaabta birta.Dusha sare waa in la nadiifiyaa kahor ilaalinta dahaarka.Boqolaal badeecooyin iyo warshado ah oo ay ku jiraan maraakiibta, haamaha kaydinta, buundooyinka, dhismayaasha birta, saldhigyada korontada, baabuurta, gawaarida, qalabka militariga, qalabka hawada, iwm waa in dusha lagu daaweeyaa ka hor inta aan la damin.Abrasive biraha waa dhexdhexaadinta nadiifinta ugu waxtarka badan.

Abrasives bir ah

Guud ahaan, waxaa jiradarbo bir tuuray (toogashada birta kaarboon sareiyotoogashada birta kaarboon hoose), bir bir ah, birta toogashada, birta birta ah,bir aan bir lahayn oo la gooyey silig/ shot conditioned, bir bir ah oo aan lahayn,bir gooyay silig, sita sharooto bir ah, iwm. Waxqabadka sare ee birta ma fududa in la jebiyo, boodhka hooseeya, isticmaalka hooseeya, waxtarka nadiifinta sare, iyo waxqabadka guud ee wanaagsan ee alaabta.Waxa ay si weyn u dhimi kartaa heerka isticmaal ee isticmaalaha ugu dambeeya, taaso hoos u dhigaysa kharashaadka iyo yaraynta qiiqa.

Haddaba su'aashu waxay tahay, sidee loo dooran karaa biraha tayo sare leh ee abrasives?

Si loo hubiyo in natiijada daaweynta dusha sare ay si buuxda u tahay heerka caadiga ah, labada tilmaame ee asaasiga ah ee abrasives biraha: waxtarka nadiifinta iyo isticmaalka.

Dhowr ismaandhaaf ah oo ku saabsan xulashada tallaalada birta ee shubka ah:

Toogashada birta kabka ah miyay ka fiican tahay?

Cabbirku ma labbis badan yahay, ka wanaagsan yahay?

The muuqaalka dhalaalaya, ka wanaagsan?

Toogashada birta kabka ah miyay ka fiican tahay?

Jawaab: Maya.

Habka samaynta iyo diyaarinta tallaalada birta, birta dhalaalaysa waa la qaboojiyaa dareere ilaa adag, wayna yaraataa inta lagu jiro habka qaboojinta.Yarayntan waxaa lagu fuliyaa xaalad xor ah, mana jirto wax kac ah sida shubista shubista si qayb ahaan loogu kabo birta dhalaalaysa halkaasoo mugga yaraynta ka dib uu hoos u dhaco, sidaas darteed qaybo elliptical ah oo leh dusha sare ee hoos u muuqda.Qaybaha noocan oo kale ah ayaa soo maray hoos u dhac ku filan, qaabkuna ma wareegsana laakiin qaab-dhismeedku waa cufan.Si kastaba ha ahaatee, haddii tallaalka birta ah ee aan si buuxda loo qandaraasin, qaabdhismeedku ma aha mid cufan, waxaa jira cillado gudaha ah sida porosity-ka oo yaraada iyo godadka hoos u dhaca.

Tuurista tamarta E = 1/2mv2, haddii qaab-dhismeedku cufan yahay, oo leh mug isku mid ah, tayada cufnaanta weyn ee M waa, saamaynta tamarta weyn, iyo sidoo kale ma fududa in la jebiyo.Sidan, sax maaha: birta wareega ayaa si fiican u toogtay.

Cabbirka hadhuudhka birta toogashada miyay ka badan tahay lebis, way ka wanaagsan tahay?

Jawaab: Maya.

Goobta nadiifinta, dusha sare ee shaqada in la nadiifiyo ama lagu buufiyo waxay samayn doontaa godad dusha la nadiifiyey.Kaliya marka godadka iyo godadka ay si buuxda isugu dhuftaan, oogada oo dhan ayaa si fiican loo nadiifin karaa.

Inta lebbiska ah ee cabbirka walxaha birta ah waa, way dheer tahay waxay qaadanaysaa in la gaadho isku-xidhka buuxa ee godadku. Wixii xabbado bir ah oo leh saamiga isku-dhafka cabbirka qaybeed gaar ah, tallaalada birta waaweyn ee inta badan loo isticmaalo nadiifinta, iyo tallaalada birta yar yar. waxay nadiifin doontaa inta u dhaxaysa aagga lagu daaweeyay tallaalada birta ee waaweyn

The muuqaalka dhalaalaya, ka wanaagsan?

Jawaab: Maya.

Hadda waxa jira laba nooctoogashada birta kaarboon sare: xabbad bir ah oo qudha oo deminaysa iyo xabbad bir ah oo labanlaabanaysa.Way adag tahay in la kala saaro halabuurka, engegnaanta, iyo qaab-dhismeedka biraha.Si kastaba ha ahaatee, toogashada birta ee labanlaabantay waxay leedahay miro wanaagsan iyo nolol daal sare leh, Miraha birta birta ah ee birta ah ee birta ah ayaa ah mid aan fiicneyn, nolosha daalkuna waa mid hooseeya. dusha sare waa dhuuban, waxay u egtahay mid aad u iftiimaya;halka birta la toogtay ka dib daawaynta labaad ee daminta, filimka Fe3O4 ee dusha sare wuxuu noqonayaa mid dhumuc weyn, kama tarjumayso iftiin, oo uma eka mid dhalaalaya.Markaa dusha sare ee dhalaalaysa macnaheedu maaha wax soo saarka ka wanaagsan, laakiin haddii ay tahay xabbad bir ah oo labanlaabanaysa ama haddii kale waa arrin aad muhiim u ah.
