I-abrasive ithetha ukuba nomphezulu orhabaxa okanye ukuthungwa kwaye ukwazi ukunxiba imathiriyeli ngokukhuhlana. Isenokusetyenziswa ukuchaza abantu, izenzo, okanye izinto ezifana isandpaper okanye emery.
I-abrasive yimathiriyeli, idla ngokuba yiminerali, esetyenziselwa ukubumba okanye ukugqiba i-workpiece ngokukhuhla okukhokelela ekubeni inxalenye ye-workpiece iguge. Ngelixa ukugqiba imathiriyeli kusoloko kuthetha ukuyipholisha ukuze ifumane indawo egudileyo, ebonakalisa ukukhanya, inkqubo inokubandakanya ukurhabaxa njengakwisatin, imatte okanye iibeaded finishes.
Kweli nqaku, ndiza kuchaza intsingiselo yegama, kwaye ndiza kwabelana ngeenyani ezinomdla malunga nalo.
Kule posi siza kugubungela:
Ubume bezinto eziphathekayo
Xa sisiva igama elithi "i-abrasive," ngokuqhelekileyo sicinga ngento eyenza umonakalo okanye igugile ngokukhuhla okanye ukucola. Isenokuba sisenzo somzimba okanye igama elichazayo elisetyenziselwa ukuchaza ukuziphatha komntu. Nangona kunjalo, kumxholo wezinto eziphathekayo, i-abrasive ibhekisela kwinto enokususa izinto ezingaphezulu ngokuguba okanye ukuxubha.

Inqanaba lokugqibela: Ukuwisa amakrele
Kwimeko yamakrele, inqanaba lokugqibela lokulola kukubhuqa. Oku kubandakanya ukusebenzisa umtya wesikhumba oqatywe ngekhompawundi erhabaxa ecolekileyo ukuze ufikelele kumphetho obukhali. Le nkqubo ithathwa njengento ebalulekileyo kwiinkemba zaseJapan kwaye ihlala ihambelana nexabiso eliphezulu kunye nomgangatho.
Umbono ongeyiyo oqhelekileyo malunga neMathiriyeli eAbrasive
Ngokwahlukileyo kwinkolelo eqhelekileyo, izinto ezirhabaxa aziyonakalisi. Zisivumela ukuba sifezekise ukugqiba okucocekileyo kunye nokucoceka kwiindawo, kwaye zinokusetyenziswa ngokufanelekileyo ngaphandle kokwenza umonakalo. Into ephambili kukukhetha izinto ezifanelekileyo zokukrazula umsebenzi okhoyo kwaye uyisebenzise ngokufanelekileyo.
Izinto ezixutywayo zihlelwa ngokusekelwe kuhlobo lwenkqubo yokusika okanye yokugaya ezisetyenziselwa yona. Olunye lolona hlelo luqhelekileyo lubandakanya:
- Ukusila: Oku kubandakanya ukusebenzisa izinto ezirhawukayo ukususa izinto kwisixhobo sokusebenza.
- Ukupholisha: Oku kubandakanya ukusebenzisa imathiriyeli enokugqabhuka ukuphucula umphezulu wesixhobo sokusebenza.
- I-Honing: Oku kubandakanya ukusebenzisa imathiriyeli e-abrasive ukwenza lula kunye nokuphucula ukuchaneka kwendawo yokusebenza.
Ukugqwesa ubuGcisa be-Abrasives: Iingcebiso kunye noBuchule
Xa kuziwa kwizinto ezixutywayo, kukho uluhlu olubanzi lweenketho ezikhoyo. Nazi ezinye zezona ntlobo zixhaphakileyo ze-abrasives kunye nokusetyenziswa kwazo:
- Iibrasives zendalo: Ezi ziquka imathiriyeli efana nesanti, ipumice, kunye ne-emery. Ngokuqhelekileyo zisetyenziselwa ukugalela, ukugulisa, kunye nokulolonga.
- Iibrasives zokwenziwa: Ezi ziquka i-silicon carbide, i-aluminium oxide, kunye ne-boron nitride. Ngokuqhelekileyo zisetyenziselwa ukugaya, ukusika kunye nokulola.

Imbali yee-Abrasives
Ukusetyenziswa kwe-abrasives kubuyela kumaxesha amandulo, kunye nobungqina bokuba amaShayina asebenzisa izinto ezixubileyo ukuze alole kunye nezixhobo zokupolisha kude kube ngu-3000 BC. Ukusetyenziswa kwamandla ombane ukwenza iibrasives kwaqala ngasekupheleni kwenkulungwane ye-19, ngokusekwa kweNkampani yeCarborundum. Namhlanje, iibrasives zisetyenziswa kuluhlu olubanzi lwamashishini kunye nokusetyenziswa kwihlabathi jikelele.
isiphelo
I-Abrasive ligama elisetyenziswa ukuchaza into erhabaxa nengathandekiyo.
Kufuneka usebenzise izinto ezinqabileyo zokususa izinto ezivela kumphezulu. Kubalulekile ukukhetha i-abrasive efanelekileyo yomsebenzi kwaye uyisebenzise ngokuchanekileyo. Ngoko ke, musa ukoyika ukucela iingcebiso kumhlobo wakho onochuku!
NdinguJoost Nusselder, umseki weZixhobo zeGqirha, umthengisi womxholo, kunye notata. Ndiyathanda ukuzama izixhobo ezitsha, kwaye kunye neqela lam ndiye ndenza amanqaku ebhlog anzulu ukusukela ngo-2016 ukunceda abafundi abathembekileyo ngezixhobo kunye neengcebiso zokwenza.
