Polycrystalline Diamond (PCD) Lisebelisoa tsa ho Seha

Nts'etsopele ea lisebelisoa tsa ho itšeha tsa PCD

Taemane e le sesebelisoa se thata haholo se sebelisoang ho seha, se nang le nalane ea makholo a lilemo. Ts'ebetsong ea nts'etsopele ea ho seha lisebelisoa ho tloha qetellong ea lekholo la bo19 la lilemo ho isa bohareng ba lekholo la bo20 la lilemo, lisebelisoa tsa lisebelisoa li ne li emeloa haholo ke tšepe e phahameng. Ka 1927, Jeremane e ile ea qala ho etsa lisebelisoa tsa lisebelisoa tsa carbide 'me tsa fumanoa li sebelisoa haholo.

Lilemong tsa bo-1950, Sweden le United States ka ho latellana li ile tsa kopanya lisebelisoa tsa maiketsetso tsa daemane, kahoo tsa kena nakong e emetsoeng ke lisebelisoa tse thata haholo. Lilemong tsa bo-1970, polycrystalline diamond (PCD) e ile ea etsoa ka theknoloji e phahameng ea khatello ea maikutlo, e ileng ea atolosa boholo ba lisebelisoa tsa litaemane ho lifofane, sefofane, likoloi, lisebelisoa tsa elektroniki, majoe le likarolo tse ling.

Litšobotsi tsa ts'ebetso ea lisebelisoa tsa PCD

Lisebelisoa tsa ho itšeha ka daemane li na le litšobotsi tsa boima bo phahameng, matla a phahameng a khatello, conductivity e ntle ea mocheso, le ho roala ho hanyetsa, tse ka finyellang ho nepahala ho phahameng le ho sebetsa hantle ha ho itšeha ka lebelo le phahameng.

Tšebeliso ea lisebelisoa tsa PCD

Ho tloha ha daemane ea pele ea polycrystalline e entsoe Sweden ka 1953, lipatlisiso mabapi le ts'ebetso ea ho itšeha ea lisebelisoa tsa PCD li fihletse liphetho tse ngata, mme sebaka sa ts'ebeliso le ts'ebeliso ea lisebelisoa tsa PCD li atolohile ka potlako.

Hona joale, baetsi ba machaba ba tummeng ba litaemane tsa polycrystalline haholo-holo ba kenyelletsa De Beers Company ea United Kingdom, GE Company ea United States, Sumitomo Electric Co., Ltd. ea Japane, joalo-joalo Ho tlalehoa hore karolong ea pele ea 1995, Tlhahiso ea lisebelisoa tsa PCD ea Japane feela e fihletse likotoana tse 107,000. Bophahamo ba ts'ebeliso ea lisebelisoa tsa PCD bo atolohile ho tloha ts'ebetsong ea pele ea ho fetolela ho ea lits'ebetsong tsa ho cheka le ho sila. Phuputso e entsoeng ka lithulusi tse thata ka ho fetisisa e entsoeng ke mokhatlo oa Majapane e bontšitse hore lintlha tse ka sehloohong tsa batho ho khetha lisebelisoa tsa PCD li itšetlehile ka melemo ea ho nepahala ha holim'a metsi, ho nepahala ha sebopeho, le bophelo ba lisebelisoa ka mor'a ho sebetsa ka lisebelisoa tsa PCD. Theknoloji ea ho kopanya lipampiri tse entsoeng ka litaemane le eona e ntlafalitsoe haholo.

Lisebelisoa tsa ZZBETTER PCD

Lisebelisoa tsa ZZBETTER PCD li kenyelletsa limaraka tse fapaneng le litlhophiso tse fapaneng. Mofuta oa sehlahisoa o kenyelletsa limaraka tse nang le boholo ba lijo-thollo tse tloaelehileng ho tloha ho li-microns tse 5 ho isa ho tse 25 le bophara ba 62mm bo ka sebelisoang. Lihlahisoa li fumaneha e le li-discs tse felletseng kapa malebela a sehiloeng ka botenya bo fapaneng ka kakaretso le botenya ba PCD.

Melemo ea ho sebelisa ZZBETTER PCD ke hore e fana ka ts'ebetso e ts'eptjoang le e tsitsitseng ka theko ea tlholisano. E ntlafatsa boiketlo ba ho etsa masela, e nolofalletsa litefiso tse phahameng tsa phepelo, 'me e fana ka khanyetso e ntlafalitsoeng bakeng sa lisebelisoa tse fapaneng tsa mosebetsi. E na le limaraka tse ngata tse nang le tungsten carbide additive ho PCD layer, e nolofalletsang baetsi ba lisebelisoa ho ntša mechine ea motlakase (EDM) le / kapa li-grind discharge (EDG) ka potlako. Mefuta ea eona e pharaletseng ea limaraka e lumella ho tenyetseha ha ho khethoa thepa e nepahetseng bakeng sa ts'ebeliso efe kapa efe ea machining

Bakeng sa ho sebetsa ka lehong

Eketsa litefiso tsa phepelo le ho ntlafatsa bophelo ba lisebelisoa lits'ebetsong tsa mapolanka tse kang medium-density fiberboard (MDF), melamine, laminates, le particleboard.

Bakeng sa indasteri e boima

Eketsa khanyetso ea ho roala 'me u fokotse nako ea ho thella lejoeng la machining, konkreite, boto ea samente le lisebelisoa tse ling tsa abrasive.

Lisebelisoa tse ling

Fokotsa litšenyehelo tsa lisebelisoa 'me u eketse botsitso bakeng sa mefuta e mengata e fapaneng ea lisebelisoa tse thata ho ea mochini, joalo ka li-composites tsa khabone, li-acrylics, khalase le lisebelisoa tse ling tse ngata tse senang ferrous le tse se nang tšepe.

Likarolo ha li bapisoa le lisebelisoa tsa tungsten carbide:

1, boima ba PCD ke makhetlo a 80 ho isa ho a 120 ho feta a tungsten carbide.

2. Thermal conductivity ea PCD ke 1.5 Ho 9 linako tse ling tsa tungsten carbide.

3. Bophelo ba lisebelisoa tsa PCD bo ka feta bophelo ba lisebelisoa tsa carbide ho 50 ho isa ho makhetlo a 100.

Likarolo ha li bapisoa le lisebelisoa tsa daemane tsa tlhaho:

1, PCD e hanyetsana ho feta litaemane tsa tlhaho ka lebaka la sebopeho se sa tloaelehang sa likaroloana tsa daemane 'me se tšehetsoa ke substrate ea carbide.

2, PCD e lula e apere ka lebaka la tsamaiso e feletseng ea tlhahiso bakeng sa taolo ea boleng bo tsitsitseng, taemane ea tlhaho ke kristale e le 'ngoe ka tlhaho' me e na le lijo-thollo tse bonolo le tse thata ha li etsoa lisebelisoa. E ke ke ea sebelisoa hantle ka lijo-thollo tse bonolo.

3, PCD e theko e tlase ebile e na le libopeho le boholo bo fapaneng tseo u ka khethang ho tsona bakeng sa lisebelisoa, taemane ea tlhaho ke moeli oa lintlha tsena.

Lisebelisoa tsa ho itšeha tsa PCD li sebelisoa haholo indastering ka lebaka la boleng ba tsona bo botle ba ts'ebetso le moruo oa ts'ebetso. E bonts'a melemo eo lisebelisoa tse ling li ke keng tsa e bapisa le lisebelisoa tse seng tsa tšepe, litšepe tse se nang ferrous le lisebelisoa tsa tsona tsa alloy, le lisebelisoa tse ling tsa ho itšeha. Ho teba ha lipatlisiso tsa theory mabapi le lisebelisoa tsa ho itšeha tsa PCD ho khothalletsa boemo ba lisebelisoa tsa PCD tšimong ea lisebelisoa tse thata haholo. PCD e tla ba ea bohlokoa le ho feta, 'me sebaka sa ts'ebeliso ea eona le sona se tla atolosoa le ho feta.
