1. Kodi atsamba la diamondi lozungulira
Chitsamba chozungulira cha diamondindi chida chodulira chomwe chimagwiritsidwa ntchito kwambiri, chomwe ndi tsamba la macheka lomwe lili ndi m'mphepete mwa diamondi yomwe ili mkati kapena kunja kwa tsamba la macheka.Amagwiritsidwa ntchito kwambiri pokonza zinthu zolimba komanso zowonongeka monga miyala ndi zoumba.Tsamba la diamondi limapangidwa makamaka ndi magawo awiri: gawo lapansi ndi tsamba.Gawo laling'ono ndilo gawo lalikulu lothandizira pazitsulo zomatira, pamene tsamba ndilo gawo locheka lomwe limayamba kugwiritsidwa ntchito.Tsambalo lidzadya nthawi zonse mukamagwiritsa ntchito, pomwe gawo lapansi silidzatero.Tinthu ta dayamondi timakutidwa ndi chitsulo mkati mwa mutu wodulira, womwe umagwira ntchito yodula pakudumpha kwa chinthu chokonzedwa panthawi yopanga makina.Pogwiritsa ntchito, matrix achitsulo ndi diamondi amadyedwa pamodzi.Nthawi zambiri zimakhala zabwino kuti matrix achitsulo azidya mwachangu kuposa diamondi, zomwe zimatsimikizira kuthwa kwa mutu wodula komanso moyo wautumiki wa mutu wodula.
Kutalika kwa diameter kwamasamba ozungulira a diamondindi yaikulu, yokhala ndi masamba osema a mamilimita angapo ndi macheka aakulu a mamita angapo m’mimba mwake.Palinso zinthu zambiri zodula, ndipo mapangidwe, kuuma, ndi kukula kwa zinthu zodula zimasiyana kwambiri.Chifukwa chake, njira zawo zopangira ndi kupanga, zida zomwe zimagwiritsidwa ntchito, komanso zofunikira zogwiritsira ntchito ndizosiyana.
2, Gulu lamasamba ozungulira a diamondi
Chitsamba chozungulira cha diamondipakali pano ndi chida chogwiritsidwa ntchito kwambiri chocheka pamakampani amiyala aku China, omwe nthawi zambiri amakhala ozungulira.Amagwiritsa ntchito njira monga zitsulo za ufa kapena electroplating kuti atseke tinthu ta diamondi mozungulira gawo lapansi.Kugwiritsa ntchito mphamvu yayikulu komanso kuuma kwa tinthu tating'ono ta diamondi kumeta ndi kuphwanya zida zina podula.Pali mitundu yambiri yamasamba ozungulira a diamondindipo kugawa kwawo kulinso kovuta kwambiri.Nthawi zambiri pamakhala njira zingapo zogawira:
1. Gulu potengera njira yopangira:
(1) Chitsamba cha macheka a diamondi
Pali mitundu iwiri ya sintering: ozizira press sintering ndi otentha press sintering.
(2) Kuwotchera macheka a diamondi
Pali mitundu iwiri ya brazing ndi kuwotcherera kwa laser.Brazing ndikuwotcherera mutu wodula ndi gawo lapansi palimodzi kudzera pa sing'anga yotentha kwambiri yosungunuka, monga tsamba la macheka okwera kwambiri, tsamba la vacuum brazing macheka, ndi zina zambiri;Kuwotcherera kwa laser kumagwiritsa ntchito mtengo wapamwamba wa laser kusungunula mutu wodula komanso m'mphepete mwa gawo lapansi kuti mupange mgwirizano wazitsulo.
(3) Tsamba la diamondi lamagetsi
Ndi njira yolumikizira ufa wa tsamba ku gawo lapansi kudzera mu electroplating.Komabe, chifukwa cha kuipitsidwa kwakukulu, dzikolo likuthetsa pang'onopang'ono njira iyi ya electroplating.
2. Gulu pokonza chinthu:
Tsamba la Marble kudula, tsamba la macheka a granite, tsamba la macheka a konkriti, ndi zina zotero.
3. Gulu potengera maonekedwe:
Macheka osalekeza m'mphepete, masamba amtundu wa tsamba, masamba amtundu wa turbine, ndi zina zotero.masamba ozungulira a diamondi, ndipo palinso zolinga zambiri zapaderamasamba ozungulira a diamondi.Sankhani mitundu yosiyanasiyana ya miyala ya diamondi yopangira zida zosiyanasiyana.
3, Makhalidwe akuluakulu atsamba la diamondi lozungulirakudula
Zozungulira macheka tsamba kudula ali ubwino ntchito yabwino, dzuwa mkulu, ndi wabwino processing khalidwe.Koma phokosolo ndi lalikulu ndipo kulimba kwa tsamba ndi kosauka.Panthawi yodula, tsamba la macheka limakonda kugwedezeka ndi kupatuka, zomwe zimapangitsa kuti ntchitoyo isafanane bwino.
4. Zinthu zomwe zimakhudza magwiridwe antchito komanso nthawi ya moyo wamasamba ozungulira a diamondi
Zinthu zomwe zimakhudza magwiridwe antchito komanso moyo wautali wamasamba ozungulira a diamondizikuphatikizapo kudula ndondomeko magawo, diamondi kalasi, tinthu kukula, ndende, ndi chomangira kuuma.
1. Kucheka magawo
(1) Kuthamanga kwa macheka
Mu ntchito zothandiza, liniya liwiro lamasamba ozungulira a diamondindi malire ndi zinthu zida, macheka tsamba khalidwe, ndi katundu mwala wochekedwa.Pankhani ya moyo wautumiki ndi kudula bwino kwa tsamba la macheka, liwiro la mzere wa tsamba la macheka liyenera kusankhidwa potengera momwe miyala ikuyendera.
(2) Kuzama kwa macheka
M'kati mwazovomerezeka zamakina ogwiritsira ntchito macheka ndi mphamvu ya zida, kuya kokulirapo kuyenera kusankhidwa momwe mungathere kuti muchepetse bwino.Pakakhala zofunikira pamakina opangidwa ndi makina, kudula kwakung'ono kuyenera kugwiritsidwa ntchito.
(3) Liwiro la chakudya
Liwiro la chakudya ndi liwiro la chakudya cha mwala womwe umachekedwa.Mtengo wake uyenera kusankhidwa potengera zomwe zili mwala wocheka.Nthawi zambiri, kudula miyala yofewa, monga nsangalabwi, kumatha kukulitsa kuzama kwa macheka ndikuchepetsa liwiro la chakudya, zomwe zimapangitsa kuti macheke achuluke.Kucheka bwino-grained granite ndi homogeneous granite kumatha kuwonjezera liwiro la chakudya moyenera.Ngati liwiro la chakudya ndilotsika kwambiri, tsamba la diamondi limaphwanyidwa mosavuta.Komabe, pocheka miyala ya granite yokhala ndi njere zolimba komanso kuuma kosafanana, liwiro lodulira liyenera kuchepetsedwa, apo ayi zipangitsa kuti tsamba la macheka ligwedezeke ndikupangitsa kuti diamondi igawike, potero kuchepetsa kudulidwa.
2. diamondi tinthu kukula
Kukula kwa diamondi komwe kumagwiritsidwa ntchito nthawi zambiri kumayambira 30/35 mpaka 60/80 mauna.Kulimba kwa thanthwe, kukula kwa tinthu kuyenera kusankhidwa.Chifukwa pansi pa zovuta zomwezo, diamondi imakhala yabwino kwambiri, imakhala yakuthwa kwambiri, yomwe imakhala yopindulitsa podula miyala yolimba.Kuphatikiza apo, masamba ambiri am'mimba mwake amafunikira kudulidwa kwakukulu, ndipo makulidwe a tinthu tating'onoting'ono monga 30/40 mauna ndi 40/50 mauna ayenera kusankhidwa;Masamba ang'onoang'ono ocheka amakhala ndi ntchito yodula kwambiri ndipo amafunikira magawo odulira miyala.Ndikoyenera kusankha kukula kwa tinthu tating'ono, monga 50/60 mauna ndi 60/80 mauna.
3. Kukhazikika kwa diamondi
Kuphatikizika kwa diamondi kumatanthawuza kuchuluka kwa kugawa kwa diamondi pamatrix ogwirira ntchito.Malinga ndi malamulo, ndende ya 4.4 carats wa diamondi pa kiyubiki centimita ntchito wosanjikiza masanjidwewo ndi 100%, ndipo ndende ya 3.3 carats diamondi ndi 75%.Kuchuluka kwa voliyumu kumayimira kuchuluka kwa diamondi mu chipikacho ndipo kumatanthawuza kuti kuchuluka kwake ndi 100% pomwe voliyumu ya diamondi imakhala 1/4 ya voliyumu yonse.Kuchulukitsa kuchuluka kwa diamondi kukuyembekezeka kukulitsa nthawi ya moyo wa tsamba la macheka, chifukwa kukulitsa ndende kumachepetsa mphamvu yodulira ya diamondi iliyonse.Koma kuonjezera ndende kudzawonjezera mtengo wa macheka, kotero pali ndalama zambiri zomwe zimawonjezeka ndi kuwonjezeka kwa macheka.
4. Kulimba kwa chomangira mutu wodula:
Nthawi zambiri, kulimba kwa chomangira kumakwera kwambiri, kulimba kwake kumakhala kolimba.Choncho, powona miyala yokhala ndi abrasiveness yapamwamba, kuuma kwa binder kumakhala kosavuta;Mukawona miyala yofewa, kuuma kwa binder kuyenera kukhala kochepa;Mukamacheka miyala yokhala ndi abrasiveness kwambiri komanso kuuma, kuuma kwa binder kuyenera kukhala kocheperako.
5, The Development Trend ofMasamba a Diamondi Ozungulira
Masamba ozungulira a diamondindi zida zazikulu mumakampani opanga miyala.M'zaka zaposachedwapa, chiwerengero cha diamondi yokumba ntchito mu makampani processing mwala wakwera kwambiri, ndi ntchitomasamba ozungulira a diamondiikuchulukiranso.Ponseponse, chitukuko chamasamba ozungulira a diamondim'dziko muno ndi m'mayiko onse ali ndi makhalidwe otsatirawa: kupanga macheka bwino ndi apamwamba, ndi kupanga macheka tsamba kalasi mwapadera diamondi;Samalani kwambiri pakufufuza kwa ufa, matrix, ndi njira ya sintering;Samalirani kwambiri kafukufuku pa sawability ndi macheka limagwirira wa zipangizo mwala;Laser kuwotcherera macheka tsamba yapangidwa;Kukula mopambanitsamasamba ozungulira a diamondi.Pakali pano, ntchito yamasamba ozungulira a diamondikukufalikira mowonjezereka.M'tsogolomu, malangizo a chitukuko chamasamba ozungulira a diamondindi kupititsa patsogolo kudula bwino, moyo wa macheka, kuchepetsa ndalama zopangira, komanso kuteteza chilengedwe.
