I-Abrasive isho ukuba nendawo emangelengele noma ukuthungwa futhi ukwazi ukuguga izinto ngokungqubuzana. Ingasetshenziswa ukuchaza abantu, izenzo, noma izinto ezifana nalezi iphepha lomhlabathi noma emery.
I-abrasive iyimpahla, ngokuvamile eyiminerali, esetshenziselwa ukubumba noma ukuqedela ucezu lomsebenzi ngokuhlikihla okuholela ekutheni ingxenye yomsebenzi iguge. Ngenkathi ukuqedela into esetshenziswayo ngokuvamile kusho ukuyipholisha ukuze uthole indawo ebushelelezi, ecwebezelayo, inqubo ingase futhi ibandakanye ukuqina njengokuqedwa kwe-satin, i-matte noma yobuhlalu.
Kulesi sihloko, ngizochaza incazelo yegama, futhi ngizokwabelana ngamaqiniso athakazelisayo ngalo.
Kulokhu okuthunyelwe sizomboza:
Isimo Esibi Sezinto
Uma sizwa igama elithi “abrasive,” sivamise ukucabanga ngento edala umonakalo noma egugile ngokukhuhla noma ngokusila. Kungaba isenzo somzimba noma igama elichazayo elisetshenziselwa ukuchaza ukuziphatha komuntu. Kodwa-ke, kumongo wezinto zokwakha, i-abrasive isho into engasusa izinto ezingaphezulu ngokugaya noma ngokuhlikihla.
Izibonelo Zezinto Eziqhumayo
Izinto ezi-brasive ziza ngezinhlobo ezahlukene, ubukhulu, kanye nokwakheka, futhi zikhiqizwa ngezinhloso ezehlukene. Ezinye izibonelo zezinto ezi-abrasive zihlanganisa:
- Idayimane: Lena into eqine kakhulu yokugwaza futhi ijwayele ukusetshenziselwa ukusika nokupholisha izindawo eziqinile.
- Itshe lemvelo: Amatshe afana ne-sandstone ne-granite asetshenziselwa ukulola imimese namanye amathuluzi okusika.
- Ama-abrasives ahlanganisiwe: Lawa ama-abrasive compounds ahlanganiswe ndawonye ukuze akhe isondo lokugaya. Zivame ukusetshenziselwa ukupholisha nokucija.
- Ama-Compounds: Lawa ama-abrasive compounds asetshenziswa phezulu ukuze afinyelele isiphetho esifunekayo. Zivame ukusetshenziselwa ukupholisha nokuhlanza.
- I-Sandpaper: Lolu uhlobo lwempahla e-brasive esetshenziselwa ukususa izinto ezingaphezulu ngokukhuhla noma ngokugaya.
Ukubaluleka Kokukhetha I-Abrasive Material Elungile
Ukukhetha into efanele yokugwaza kubalulekile ukuze ufinyelele isiphetho osifunayo futhi ugweme ukubangela umonakalo endaweni okusetshenzwa kuyo. Izinto okufanele zicatshangelwe lapho ukhetha i-abrasive material zifaka:
- Ubunjalo bomhlaba osetshenzwa kuwo
- Isiphetho osifunayo
- Uhlobo lomsebenzi owenziwayo
- Isikhathi nemali etholakalayo yomsebenzi
Isigaba Sokugcina: Ukunqamula Izinkemba
Endabeni yezinkemba, isigaba sokugcina sokulola ukugunda. Lokhu kuhilela ukusebenzisa ibhande lesikhumba elimbozwe ngenhlanganisela ecijile kahle ukuze kufinyelelwe umphetho obukhali. Le nqubo ibhekwa njengebalulekile ezinkembeni zaseJapane futhi ngokuvamile ihlotshaniswa nenani eliphezulu nekhwalithi.
Umbono Oyiphutha Ovamile mayelana Nezinto Ezixubhayo
Ngokuphambene nenkolelo evamile, izinto ezihuquzelayo azikonakali ngempela. Zisivumela ukuthi sifinyelele isiphetho esibushelelezi nesihlanzekile ezindaweni ezingaphezulu, futhi zingasetshenziswa ngokuphumelelayo ngaphandle kokudala umonakalo. Isihluthulelo siwukukhetha izinto ezilumayo ezifanele zomsebenzi owenziwayo futhi uyisebenzise ngendlela efanele.
Izinto eziqhumayo zihlukaniswa ngokusekelwe ohlotsheni lwenqubo yokusika noma yokugaya ezisetshenziselwa yona. Ezinye zezigaba ezivame kakhulu zihlanganisa:
- Ukugaya: Lokhu kuhilela ukusebenzisa izinto eziqhumayo ukuze kukhishwe into ethile kucezu lokusebenza.
- Ukupholisha: Lokhu kuhilela ukusebenzisa izinto ezilumayo ukuze kuthuthukiswe indawo engaphezulu yesiqeshana sokusebenza.
- I-Honing: Lokhu kuhilela ukusebenzisa izinto ezilumayo ukuze kusheleleke futhi kuthuthukiswe ukunemba kocezu lokusebenza.
Ukuba ingcweti kwezobuciko be-Abrasives: Amathiphu Namasu
Uma kuziwa ezintweni ezi-abrasive, kunezinhlobonhlobo zezinketho ezitholakalayo. Nazi ezinye zezinhlobo ezivame kakhulu zama-abrasives kanye nokusetshenziswa kwazo:
- Ama-abrasive emvelo: Lezi zihlanganisa izinto ezifana nesihlabathi, i-pumice, ne-emery. Zivame ukusetshenziselwa ukusetshenzelwa isihlabathi, ukupholishwa, nokucijwa.
- Ama-abrasives okwenziwa: Lezi zihlanganisa i-silicon carbide, i-aluminium oxide, ne-boron nitride. Ngokuvamile zisetshenziselwa ukugaya, ukusika, nokulola.
- Ama-abrasive edayimane: Lawa athathwa njengokukhetha okuphezulu kokupholishwa nokucijwa ngenxa yokuqina kwawo okwedlulele.
Ukukhetha I-Abrasive Efanelekile Yezidingo Zakho
Lapho ukhetha into e-abrasive, kunezici ezimbalwa ezibalulekile okufanele uzicabangele:
- Ukuqina: Ukuqina kwensimbi e-abrasive kufanele kube kukhulu kunempahla esetshenzwayo.
- Umumo: Umumo we-abrasive material ungathinta ukuphela nokusebenza kahle kwenqubo.
- Usayizi: Usayizi wezinhlamvu ze-abrasive futhi ungaba nomthelela ekugcineni nokusebenza kahle kwenqubo.
Ukusebenzisa Izinto Eziqhuma Ngokuphumelelayo
Nawa amanye amathiphu okusebenzisa izinto ezilumayo ukuze uthuthukise umsebenzi wakho:
- Sebenzisa amandla afanele: Ukusebenzisa amandla amaningi kungalimaza okokusebenza okusetshenzwayo, kuyilapho amandla amancane kakhulu angase angazisusi ngempumelelo izinto ezingafuneki.
- Zigcine zomile: Izinto zokugwaza zivame ukusetshenziswa zomile, njengoba ukwengeza amanzi noma olunye uketshezi kunganciphisa ukusebenza kwazo.
- Hlanganisa futhi ufanise: Ukuhlanganisa izinhlobo ezahlukene zama-abrasive kungakha inqubo esebenza ngempumelelo nesebenza kahle.
- Ama-abrasives ahlanganisiwe: Lena imikhiqizo lapho impahla e-abrasive iboshelwe ezintweni ezisekelayo, njenge-sandpaper noma amasondo okugaya. Zihlukaniswa ngokuya ngohlobo lwe-ejenti yokubopha esetshenzisiwe.
Umlando we-Abrasives
Ukusetshenziswa kwama-abrasives kwaqala ezikhathini zasendulo, nobufakazi bokuthi amaShayina ayesebenzisa izinto ezilumayo ukulola nokupholisha amathuluzi kusukela ngo-3000 BC. Ukusetshenziswa kwamandla kagesi ukwenza ama-abrasives kwaqala ngasekupheleni kwekhulu le-19, lapho kwasungulwa iCarborundum Company. Namuhla, ama-abrasives asetshenziswa ezinhlobonhlobo zezimboni nasezisetshenziswa emhlabeni jikelele.
Isiphetho
I-Abrasive yigama elisetshenziswa ukuchaza into embi nengemnandi.
Kufanele usebenzise izinto ezi-abrasive ukuze ususe impahla endaweni. Kubalulekile ukukhetha i-abrasive efanele yomsebenzi futhi uyisebenzise ngendlela efanele. Ngakho-ke, ungesabi ukucela iseluleko kumngane wakho ohlukumezayo!
Ngingu-Joost Nusselder, umsunguli we-Tools Doctor, umakethi wokuqukethwe, kanye nobaba. Ngiyakuthanda ukuzama okokusebenza okusha, futhi kanye nethimba lami ngidale izindatshana zebhulogi ezijulile kusukela ngo-2016 ukuze ngisize abafundi abathembekile ngamathuluzi namathiphu okwenza.
