Yintoni i-PCD isarha blade?

Ukubona ukuba abantu abaninzi abazi kakhulu malunga nenkcazo ye-PCD saw blade, kuquka neengcali ezinxulumene ne-PCD i-saw blade, inkcazo enikwe ngabanye babo ayichanekanga ngokwaneleyo!

Igama elipheleleyo lesiTshayina le-PCD isarha yesarha sisishunqulelo se "polycrystalline diamond saw blade", apho iPCD sisishunqulelo sePolyCrystalline Diamond (iguqulelwe kwisiTshayina njengedayimani epolycrystalline), ngoko ke iPCD isarha isarha ikwabizwa ngokuba yidayimane.I-Saw blade, kodwa ngenxa yokuba iblade yesarha yedayimane yokusika ilitye ivele ngaphambili kakhulu kune-PCD yabona blade, iHuangrui Tool ikholelwa ukuba kulula ukubangela ukubhideka ukubiza nje i-PCD isarha blade njengoko idayimani isarha blade.Ayiqondwanga kakhulu ukuyibiza ngokuba yi-PCD diamond saw blade.
Njengoko sonke sisazi, idayimani yeyona nto inzima ekhoyo kwindalo.Yikristale eqhelekileyo ye-octahedral eyenziwe ngezinto zekhabhoni ezenziwe kwindawo enzulu yomhlaba phantsi kwesenzo soxinzelelo oluphezulu kunye nobushushu obuphezulu.Inamandla, zonke ii-electron ze-valence zibandakanyeka ekubunjweni kweebhondi ze-covalent, akukho zi-electron zamahhala ezikhoyo, ngoko ubunzima bedayimane bukhulu kakhulu, ubunzima bedayimane buphindwe ka-4 kwi-corundum kunye namaxesha angama-8 e-quartz!

Itekhnoloji yale mihla sele ikwazile ukuvelisa iikristale zokwenziwa zedayimani zokwenziwa, kwaye iPCD isebenzisa icobalt kunye nezinye iintsimbi njengezibophelelo ukwenza iipolycrystallize idayimane yokwenziwa komgubo wekristale enye kwiipolycrystals zedayimani phantsi kweemeko ezithile.Ukuqina kwale diamond polycrystalline (oko kukuthi i-PCD) nangona ingekho nzima njengedayimani yekristale enye, ukuqina kusephezulu njenge-8000HV, eyi-80 ~ 120 amaxesha e-carbide enesamente!Ngaphezu koko, uchungechunge lwe-thermal conductivity ye-PCD yi-700W / MK, eyi-2 ~ 9 amaxesha e-carbide ene-cemented, kwaye nangaphezulu kune-PCBN kunye nobhedu.Ke ngoko, usebenzisa imathiriyeli yePCB njengentloko isarha, isantya sokuhambisa ubushushu sikhawuleza kakhulu ngexesha lokusika.Ukongezelela, i-coefficient yokwandiswa kwe-thermal yezinto ze-PCD kuphela kwisihlanu se-carbide ene-cemented, kwaye i-coefficient of friction yisinye kwisithathu se-carbide ene-cemented.Ezi zakhiwo zinquma ukuba i-saw blade isebenzisa izinto ze-PCD njengentloko yokusika ilingana nomzimba we-saw blade.Ngaphantsi kweemeko ezithile, kungekhona kuphela ubomi benkonzo ye-saw blade i-theoretically ubuncinane ngamaxesha angama-30 aphezulu kune-carbide saw blade, kodwa kunye nomgangatho wokusika ungcono.Ngaphezu koko, ubudlelwane phakathi kwezixhobo zePCD kunye neentsimbi ezingenayo i-ferrous kunye nezinto ezingezo zentsimbi zincinci.Xa usika iintsimbi ezingezizo ezoni okanye izinto ezingezizo ezentsimbi, intloko yePCD cutter kwi-saw blade nayo ayinakukwazi ukudibanisa i-sawdust kunentloko ye-carbide cutter.Ekugqibeleni, kukho enye inzuzo: imathiriyeli yePCD ineasidi eyomeleleyo kunye nokuzinza kwealkali yokumelana, nayo iluncedo kakhulu kuzinzo lomgangatho weesaha zePCD.

I-PCD saw blade kukusebenzisa i-carbide enesamente njenge-matrix yezinto ze-PCD ezingaphezulu kwe-1mm, yenza indibaniselwano ngokusebenzisa i-sintering okanye ezinye iinkqubo ezicinezelayo, kwaye ekugqibeleni inlay kwi-alloy iron plate body ye-saw blade, ukuze ithathe indawo. izinto ezinzima kunye nentloko ye-PCD cutter.Ingumgca wokusika we-saw blade, ophucula kakhulu ubomi benkonzo ye-saw blade kunye nokuzinza komgangatho wokusika.

Okwangoku, ngakumbi nangakumbi abasebenzisi isarha iblade bakhetha ukusebenzisa PCD idayimani isarha iiblades kunye ultra-ixesha elide ubomi inkonzo, ezisetyenziswa ikakhulu kushishino ifanitshala yokuvelisa, ishishini non-ayoni processing metal ukuba kunzima ukusika, kunye nocango aluminiyam ingxubevange kunye nefestile. abavelisi ukuba bathathe indawo yeemela zokuqala ze-carbide.I-alloy saw blade yentloko ayinakunqunyulwa kuphela ngokuqhubekayo ixesha elide, kodwa kwakhona ayifuni ukutshintsha i-saw blade rhoqo.Ubomi obude, ngokubanzi, kunciphisa iindleko ezininzi zokusika xa kuthelekiswa nokusetyenziswa kwe-carbide saw blades!
