Zofunikira pakusankha magawo a masamba a diamondi

1. Kusankhidwa kwa diamondi particle size
Kukula kwa diamondi kukakhala koyipa komanso kosakwatiwa, mutu wa tsamba ndi wakuthwa komanso kudula bwino kumakhala kokwera, koma mphamvu yopindika ya diamondi agglomeration imachepa.Pamene granularity ya diamondi ili bwino kapena yosakanikirana, mutu wa tsamba la macheka umakhala wotalika kwambiri koma wochepa kwambiri.Poganizira zomwe zili pamwambazi, kukula kwa diamondi 50/60 ndikoyenera.
2. Kusankhidwa kwa ndende yogawa diamondi
Mumtundu wina, pamene ndende ya diamondi imasintha kuchokera kumunsi kupita kumtunda, kukhwima ndi kudula bwino kwa tsamba la macheka kumachepa pang'onopang'ono, koma moyo wautumiki umakulitsidwa pang'onopang'ono.Koma ngati ndendeyo ili yokwera kwambiri, tsambalo limakhala losalala.Pogwiritsa ntchito otsika ndende, coarse tirigu kukula, dzuwa adzakhala bwino.Kugwiritsa ntchito mbali zosiyanasiyana za mutu wa chida pocheka, pogwiritsira ntchito zosiyana siyana (ndiko kuti, m'magulu atatu kapena zigawo zambiri za mapangidwe apakati angagwiritsidwe ntchito kuti achepetse ndende), ndondomeko ya macheka akugwira ntchito pa mapangidwe. wa pakati poyambira, zabwino kuteteza macheka tsamba pendulum, kuti kupititsa patsogolo mwala processing.
3. Kusankha mphamvu ya diamondi
Mphamvu ya diamondi ndi index yofunikira kuti iwonetsetse ntchito yodula.Mphamvu yapamwamba kwambiri imapangitsa kuti kristaloyo ikhale yovuta kuthyola, tinthu tating'onoting'ono tomwe timapukutidwa tikagwiritsidwa ntchito, kukhwima kumachepa, zomwe zimapangitsa kuwonongeka kwa zida;Pamene mphamvu ya diamondi sikwanira, n'zosavuta kusweka pambuyo pa kukhudzidwa ndi zovuta kunyamula ntchito yolemetsa yodula.Chifukwa chake, mphamvuyo iyenera kusankhidwa mu 130 ~ 140N.4. Kusankhidwa kwa gawo lolumikizana
Kuchita kwa tsamba la macheka kumadalira osati diamondi yokha, komanso momwe zimagwirira ntchito zonse zamagulu omwe amapangidwa ndi kuphatikiza koyenera kwa diamondi ndi binder.Kwa nsangalabwi ndi miyala ina yofewa, makina a mutu wa chida ndi otsika, amatha kusankha binder yamkuwa.Koma kutentha kwa sintering kwa copper base binder ndikotsika, mphamvu ndi kulimba ndizochepa, kulimba kwake ndikwambiri, ndipo mphamvu yolumikizana ndi diamondi ndiyotsika.WC ikawonjezedwa, WC kapena W2C imagwiritsidwa ntchito ngati chitsulo chamafupa, ndi kuchuluka koyenera kwa cobalt kuti ipititse patsogolo mphamvu, kuuma ndi mawonekedwe olumikizana, ndi kachulukidwe kakang'ono ka Cu, Sn, Zn ndi zitsulo zina zokhala ndi malo otsika osungunuka ndi kuuma. kuwonjezeredwa ngati gawo la mgwirizano.Kukula kwa tinthu tating'ono ting'onoting'ono kuyenera kukhala kocheperako kuposa mauna 200, ndipo kukula kwa tinthu kowonjezerako kuyenera kukhala kocheperako kuposa mauna 300.
5. Kusankhidwa kwa ndondomeko ya sintering
Ndi kuwonjezeka kwa kutentha, kuchuluka kwa kachulukidwe ka nyama kumawonjezeka, momwemonso mphamvu yopindika.Komabe, pakuwonjezedwa kwa nthawi yogwira, mphamvu yopindika ya nyama yopanda kanthu ndi kuphatikizika kwa diamondi kumawonjezeka kenako kumachepa.The sintering ndondomeko 120s pa 800 ℃ akhoza kusankhidwa kukwaniritsa zofunika ntchito.
