PCD yabonye icyuma ni iki?
Urebye ko abantu benshi batazi byinshi kubisobanuro bya PCD babonye icyuma, ndetse harimo nabakora imyitozo ijyanye na PCD babonye icyuma, ibisobanuro byatanzwe na bamwe muribo ntabwo aribyo bihagije!
Izina ryuzuye ryigishinwa rya PCD saw blade ni impfunyapfunyo ya "polycrystalline diamant saw blade", aho PCD ari impfunyapfunyo ya PolyCrystalline Diamond (bisobanurwa mu gishinwa nka diyama polycrystalline), bityo PCD ibona icyuma nacyo cyitwa diyama. Yabonye icyuma, ariko kubera ko diyama yabonye icyuma cyo gutema amabuye yagaragaye hakiri kare cyane kuruta uko PCD yabonye icyuma, Igikoresho cya Huangrui cyizera ko byoroshye gutera urujijo guhamagara gusa PCD yabonye icyuma nkuko diyama yabonye icyuma. Ntabwo byunvikana cyane kubyita PCD diamant saw blade.
Nkuko twese tubizi, diyama nikintu gikomeye cyane kibaho muri kamere. Nibisanzwe bya octahedral imwe ya kirisiti igizwe nibintu bya karubone byakozwe mubice byisi byisi munsi yumuvuduko mwinshi nubushyuhe bwinshi. Mukomere, electron zose za valence zigira uruhare mukurema imiyoboro ya covalent, nta electroni yubusa ibaho, ubukana bwa diyama rero ni bunini cyane, ubukana bwa diyama bukubye inshuro 4 ubwa corundum ninshuro 8 za quartz!
Ikoranabuhanga rigezweho rimaze igihe kinini rishobora gukora diyama ya sintetike ya kristu imwe, kandi PCD ikoresha cobalt hamwe nibindi byuma nkibikoresho byo guhuza polycrystallize ya diyama ya sintetike ya pome yifu ya kirisiti muri diyama polycristal mubihe byihariye. Ubukomezi bwa diyama ya polycrystalline (ni ukuvuga PCD) ni Nubwo bitagoye nka diyama imwe ya kirisiti, ubukana buracyari hejuru ya 8000HV, bukubye inshuro 80 ~ 120 za karbide ya sima! Byongeye kandi, urukurikirane rw'amashanyarazi ya PCD ni 700W / MK, ikubye inshuro 2 ~ 9 za karbide ya sima, ndetse iruta iya PCBN n'umuringa. Kubwibyo, ukoresheje ibikoresho bya PCB nkumutwe wicyuma, umuvuduko wo kohereza ubushyuhe urihuta cyane mugihe cyo gukata. Byongeye kandi, coefficente yo kwagura ubushyuhe bwibikoresho bya PCD ni kimwe cya gatanu cyonyine cya karbide ya sima, kandi coefficente yo guterana ni kimwe cya gatatu cyonyine cya karbide ya sima. Iyi miterere igena ko icyuma kibonye ukoresheje ibikoresho bya PCD nkumutwe wogukata uhwanye numubiri wicyuma. Mubihe bimwe na bimwe, ntabwo ubuzima bwumurimo wicyuma bwonyine burenze byibuze byibuze inshuro 30 kurenza icyuma cya karbide, ariko kandi ubwiza bwubutaka bwo gukata ni bwiza. Byongeye kandi, isano iri hagati yibikoresho bya PCD nicyuma kitari ferrous nibikoresho bitari ibyuma ni bito. Iyo ukata ibyuma bidafite fer cyangwa ibikoresho bitari ibyuma, umutwe wa PCD ukata ku cyuma nawo ntushobora guhuza igiti kuruta umutwe wa karbide. Hanyuma, hari akandi karusho: ibikoresho bya PCD bifite acide ikomeye na alkali irwanya imbaraga, nayo ifasha cyane muburyo bwiza bwa PCD yabonye ibyuma.
PCD yabonye icyuma nugukoresha karbide ya sima nka matrix kubikoresho bya PCD birenga 1mm, bigakora ihuriro binyuze mu gucumura cyangwa mubindi bikorwa byingutu, hanyuma amaherezo igashyirwa kumubiri wibyuma byuma byuma byuma, kugirango bisimburwe. ibikoresho bikomeye hamwe na PCD ikata umutwe. Nibice byo gukata byuma, bitezimbere cyane ubuzima bwumurimo wicyuma kiboneye kandi gihamye cyubwiza bwo gutema.
Kugeza ubu, abantu benshi babonye ibyuma bahitamo gukoresha PCD diamant babonye ibyuma bifite ubuzima burebure bwa serivisi, bikoreshwa cyane cyane mu nganda zikora ibikoresho byo mu nzu, inganda zitunganya ibyuma bidafite ferro bigoye guca, hamwe na aluminium alloy umuryango nidirishya ababikora kugirango basimbuze ibyuma byumwimerere bya karbide. Umuti wabonye icyuma cyumutwe ntushobora gukata gusa igihe kirekire, ariko kandi ntukeneye gusimbuza icyuma kenshi. Kuramba, byuzuye, bigabanya amafaranga menshi yo kugabanya ugereranije no gukoresha karbide ibiti!
