I-Polycrystalline Diamond (PCD) Amathuluzi Okusika

Ukuthuthukiswa kwamathuluzi wokusika we-PCD

Idayimane njengethuluzi elinzima kakhulu lisetshenziselwa ukusika, onomlando wamakhulu eminyaka. Enqubweni yokuthuthukiswa kwamathuluzi okusika kusukela ekupheleni kwekhulu le-19 kuya phakathi nekhulu lama-20, izinto zamathuluzi zazimelelwe ikakhulukazi insimbi yesivinini esikhulu. Ngo-1927, iJalimane yaqala ukwenza izinto zamathuluzi e-carbide futhi yatholwa kabanzi.

Ngawo-1950, iSweden ne-United States zahlanganisa amathuluzi okusika idayimane okwenziwa ngokulandelana, ngaleyo ndlela angena enkathini emelwe izinto eziqinile kakhulu. Ngawo-1970s, idayimane le-polycrystalline (PCD) lahlanganiswa kusetshenziswa ubuchwepheshe bokuhlanganiswa kwengcindezi ephezulu, okwanweba ububanzi bokusetshenziswa kwamathuluzi edayimane kwezokundiza, i-aerospace, izimoto, izinto zikagesi, amatshe, neminye imikhakha.

Izici zokusebenza zamathuluzi e-PCD

Amathuluzi okusika idayimane anezici zobulukhuni obuphezulu, amandla aphezulu okucindezela, ukuhanjiswa okuhle kokushisa, nokumelana nokugqoka, okungafinyelela ukunemba okuphezulu kwemishini nokusebenza kahle ekusikeni ngesivinini esikhulu.

Ukusetshenziswa kwamathuluzi e-PCD

Kusukela idayimane lokuqala le-polycrystalline lahlanganiswa eSweden ngo-1953, ucwaningo ngokusika ukusebenza kwamathuluzi e-PCD seluthole imiphumela eminingi, futhi ububanzi bokusebenza nokusetshenziswa kwamathuluzi e-PCD kwande ngokushesha.

Njengamanje, abakhiqizi abadumile emhlabeni wonke bamadayimane e-polycrystalline ikakhulukazi bahlanganisa i-De Beers Company yase-United Kingdom, i-GE Company yase-United States, i-Sumitomo Electric Co., Ltd. yaseJapane, njll. Kubikwa ukuthi engxenyeni yokuqala ka-1995, Ukukhiqizwa kwethuluzi le-PCD laseJapan kuphela kufinyelele izingcezu eziyi-107,000. Ububanzi bokusebenza bamathuluzi e-PCD bunwetshiwe kusukela kunqubo yokuqala yokujika kuya ezinqubweni zokumba nokugaya. Ucwaningo lwamathuluzi aqinile olwenziwa inhlangano yaseJapane lubonise ukuthi ukucatshangelwa okuyinhloko kokuthi abantu bakhethe amathuluzi e-PCD kusekelwe ezinhlelweni zokunemba kwendawo, ukunemba kobukhulu, kanye nempilo yamathuluzi ngemva kokucubungula ngamathuluzi e-PCD. Ubuchwepheshe bokuhlanganisa amashidi ayinhlanganisela yedayimane buye bathuthukiswa kakhulu.

ZZBETTER PCD amathuluzi

Amathuluzi e-ZZBETTER PCD afaka amamaki ahlukahlukene kanye nokucushwa kwe-dimensional. Ibanga lomkhiqizo lihlanganisa amamaki anesilinganiso sosayizi wokusanhlamvu kusukela ku-5 kuya ku-25 microns kanye nobubanzi obusebenzisekayo obungu-62mm. Imikhiqizo iyatholakala njengamadiski agcwele noma amathiphu okusika ngokuhlukahluka kobubanzi obuphelele kanye nogqinsi lwesendlalelo se-PCD.

Izinzuzo zokusebenzisa i-ZZBETTER PCD ihlinzeka ngokusebenza okuthembekile nokungaguquguquki ngezindleko zokuncintisana. Ithuthukisa ukulula kokwenziwa, inika amandla amanani aphezulu okuphakelayo, futhi inikeza ukumelana okuthuthukisiwe kokugqokwa kwezinto ezihlukahlukene zokusebenza. Ihlanganisa amamaki amaningi anesengezo se-tungsten carbide kusendlalelo se-PCD, esenza abenzi bamathuluzi bakwazi ukukhipha imishini kagesi (EDM) kanye/noma ama-electrical discharge grinds (EDG) ngokushesha. Ububanzi bayo bamabanga abanzi buvumela ukuguquguquka ekukhetheni impahla efanele yanoma yiluphi uhlelo lokusebenza lomshini

Okokusebenza Ngokhuni

Khulisa amanani okuphakelayo futhi uthuthukise impilo yamathuluzi ezinhlelweni zokusebenza zezinkuni ezifana ne-medium-density fiberboard (MDF), i-melamine, i-laminates, ne-particleboard.

Okwezimboni Ezisindayo

Khulisa ukumelana nokuguga futhi unciphise isikhathi sokwenza imishini yamatshe, ukhonkolo, ibhodi likasimende, nezinye izinto zokusebenza ezilumayo.

Ezinye izinhlelo zokusebenza

Yehlisa izindleko zamathuluzi futhi wandise ukuvumelana kwebanga elibanzi lezinto eziqinile emshinini, njengezinhlanganisela zekhabhoni, ama-acrylics, ingilazi, nezinye izinto eziningi ezingenayo insimbi nezingezona ezensimbi.

Izici eziqhathaniswa namathuluzi we-tungsten carbide:

1, Ubulukhuni be-PCD buphindwe izikhathi ezingama-80 kuye kweziyi-120 kobe-tungsten carbide.

2. I-thermal conductivity ye-PCD yi-1.5 kuya ku-9 izikhathi ze-tungsten carbide.

3. Impilo yamathuluzi e-PCD ingadlula impilo yethuluzi lokusika i-carbide izikhathi ezingama-50 kuye kweziyi-100.

Izici eziqhathaniswa namathuluzi edayimane emvelo:

1, i-PCD imelana kakhulu kunamadayimane emvelo ngenxa yesakhiwo sokuma okungahleliwe sezinhlayiya zedayimane futhi isekelwa i-carbide substrate.

2, i-PCD ayiguquki kakhulu ngenxa yohlelo oluphelele lokukhiqiza lokulawula ukungaguquguquki kwekhwalithi, idayimane lemvelo liyikristalu eyodwa emvelweni futhi linezinhlamvu ezithambile neziqinile uma zenziwa ithuluzi. Ngeke isetshenziswe kahle ngezinhlamvu ezithambile.

3, i-PCD ishibhile futhi inomumo nosayizi abahlukahlukene ongakhetha kukho ukuze usetshenziswe, idayimane lemvelo liwumkhawulo kulawa maphuzu.

Amathuluzi okusika e-PCD asetshenziswa kakhulu embonini ngenxa yekhwalithi yawo enhle yokucubungula kanye nomnotho wokucubungula. Ibonisa izinzuzo amanye amathuluzi angeke afane nezinto ezingezona ezensimbi, izinsimbi ezingezona ayoni kanye nezinto zazo ze-alloy, nokunye ukucutshungulwa kokusika. Ukujula kocwaningo lwethiyori kumathuluzi okusika e-PCD kukhuthaza isikhundla samathuluzi e-PCD emkhakheni wamathuluzi aqine kakhulu. I-PCD izobaluleka kakhulu, futhi ububanzi bohlelo lwayo lokusebenza izophinde inwetshwe.
