PCD saw blade ke eng?

Lehare la saw PCD ke eng?

Ho bona hore batho ba bangata ha ba tsebe ho hongata ka tlhaloso ea PCD saw blade, esita le ho kenyelletsa litsebi tse amanang le PCD saw blade, tlhaloso e fanoeng ke ba bang ba bona ha e nepahale ka ho lekaneng!

Lebitso le feletseng la Sechaena la PCD saw blade ke khutsufatso ea "polycrystalline diamond saw blade", eo ho eona PCD e leng khutsufatso ea PolyCrystalline Diamond (e fetoletsoeng ka Sechaena e le daemane ea polycrystalline), kahoo PCD saw blade e boetse e bitsoa taemane. Lehare la saw, empa hobane lehare la daemane bakeng sa ho seha lejoe le ile la hlaha pejana ho feta PCD saw blade, Huangrui Tool e lumela hore ho bonolo ho baka pherekano ho bitsa feela PCD saw lehare joalo ka lehare la taemane. Ha e utloisisoe hampe haholo ho e bitsa PCD diamond saw blade.
Joalokaha bohle re tseba, taemane ke ntho e thata ka ho fetisisa e teng tlhahong. Ke kristale e le 'ngoe ea octahedral e tloaelehileng e entsoeng ka likarolo tsa carbon tse entsoeng karolong e tebileng ea lefats'e tlas'a ketso ea khatello e phahameng le mocheso o phahameng. E matla, li-elektronike tsohle tsa valence li kenya letsoho ho thehoeng ha litlamo tsa covalent, ha ho na li-electrone tse sa lefelloeng, kahoo boima ba daemane bo boholo haholo, boima ba daemane ke makhetlo a 4 a corundum le makhetlo a 8 a quartz!

Theknoloji ea sejoale-joale e 'nile ea khona ho hlahisa likristale tsa maiketsetso tsa daemane tse le' ngoe, 'me PCD e sebelisa cobalt le litšepe tse ling e le li-binders ho polycrystallize synthetic diamond single crystal powders ho li-polycrystals tsa daemane tlas'a maemo a itseng. Ho thatafala ha daemane ena ea polycrystalline (ke hore PCD) ke Le hoja e se thata joaloka daemane e le 'ngoe ea kristale, boima bo ntse bo le holimo ho 8000HV, e leng makhetlo a 80 ~ 120 a carbide e entsoeng ka samente! Ho feta moo, letoto la li-conductivity tsa mocheso oa PCD ke 700W / MK, e leng makhetlo a 2 ~ 9 a carbide e entsoeng ka samente, esita le e phahameng ho feta ea PCBN le koporo. Ka hona, ho sebelisa lisebelisoa tsa PCB joalo ka hlooho ea lehare la sakha, lebelo la phetisetso ea mocheso le potlakile haholo nakong ea ho itšeha. Ho phaella moo, coefficient ea katoloso ea mocheso ea thepa ea PCD ke karolo ea bohlano feela ea carbide e entsoeng ka samente, 'me coefficient of friction ke karolo ea boraro feela ea carbide e entsoeng ka samente. Lintho tsena li etsa qeto ea hore lehare la saw le sebelisa lisebelisoa tsa PCD kaha hlooho ea sehahi e lekana le 'mele oa lehare la saw. Tlas'a maemo a itseng, ha se feela bophelo ba ts'ebeletso ea lehare la saw bo nang le theory bonyane makhetlo a 30 ho feta a carbide saw blade, empa le boleng ba sebaka sa ho itšeha bo molemo. Ho feta moo, kamano pakeng tsa lisebelisoa tsa PCD le litšepe tse se nang ferrous le lisebelisoa tse seng tsa tšepe li nyenyane. Ha u seha litšepe tse se nang ferrous kapa lisebelisoa tse se nang tšepe, hlooho ea seha PCD holim'a lehare la sakha e boetse e na le monyetla o fokolang oa ho kopanya sawdust ho feta hlooho ea carbide cutter. Qetellong, ho na le molemo o mong: thepa ea PCD e na le acid e matla le botsitso ba ho hanyetsa alkali, e leng molemo haholo ho botsitso ba boleng ba li-blades tsa PCD.

The PCD saw blade ke ho sebelisa carbide e entsoeng ka samente e le matrix bakeng sa thepa ea PCD e fetang 1mm, ho etsa motsoako ka sintering kapa mekhoa e meng ea ho hatella, 'me qetellong e kenngoa holim'a' mele oa tšepe ea alloy ea lehare la saw, e le hore o nke sebaka. thepa e thata e nang le hlooho ea seha PCD. Ke karolo ea ho itšeha ea lehare la saw, e ntlafatsang haholo bophelo ba tšebeletso ea lehare la saw le botsitso ba boleng ba ho itšeha.

Hona joale, basebelisi ba lehare ba ntseng ba eketseha ba khetha ho sebelisa li-blade tsa daemane tsa PCD tse nang le bophelo bo botle ba tšebeletso ea nako e telele, tse sebelisoang haholo indastering ea tlhahiso ea thepa ea ka tlung, indasteri e sa sebetsaneng le tšepe eo ho leng thata ho e khaola, le monyako le fensetere ea motsoako oa aluminium. baetsi ba ho nka sebaka sa lithipa tsa pele tsa carbide. The alloy saw blade ea hlooho e ke ke ea khaola feela nako e telele, empa hape ha e hloke ho nkela lehare la sakha sebaka khafetsa. Ho phela nako e telele, ka botlalo, ho fokotsa litšenyehelo tse ngata tsa ho itšeha ha ho bapisoa le tšebeliso ea li-blades tsa carbide!
