Mbiri ya tsamba la diamondi

Daimondi yakhala mphamvu yofunikira kulimbikitsa chitukuko cha chuma cha dziko chifukwa cha kupambana kosayerekezeka kwa zipangizo zina.Zida za diamondi (zodula zida, zida zobowola, zida zopera, etc.) zimagwiritsidwa ntchito kwambiri pomanga nyumba, zida, pobowola mafuta, migodi ya malasha, zida zamankhwala, zakuthambo (titaniyamu aloyi, aluminium alloy processing, etc.) ndi zina zambiri. , ndipo apanga phindu lalikulu lazachuma ndi mapindu a anthu.
Pachitukuko chapadziko lonse lapansi chopanga zida za diamondi, M'zaka za m'ma 1960, chitukuko cha mafakitale chinakula mofulumira m'mayiko otukuka ku Ulaya ndi America;chakumapeto kwa zaka za m'ma 1970, Japan mwamsanga anapambana mpikisano ndi mayiko European ndi America ndi mtengo wake wotsika, Ndipo anakhala mmodzi wa atsogoleri mu makampani;Kenako, mu 1980s, Korea South m'malo Japan monga latsopano diamondi chida makampani chimphona;m'ma 1990, Ngakhale makampani China diamondi okhudzana anayamba ndi mochedwa, Koma ndi kuwuka padziko lonse wa kupanga Chinese, China diamondi chida makampani anayambanso kuyamba, Kupyolera mu khama unremitting ndi chitukuko cha mibadwo ingapo, Pakali pano, China ali masauzande diamondi. -opanga makampani okhudzana, Mtengo wapachaka umaposa yuan biliyoni 10, Khalani m'modzi mwa omwe amapereka msika wa zida za diamondi padziko lonse lapansi.
Chidziwitso cha chitukuko cha diamondi chinawoneka bwino
Kuyambira 1885, a ku France adapanga tsamba loyamba la diamondi lachilengedwe
diamondi yokhala ndi tinthu ta coarse[1~3]Ili ndi mbiri yopitilira zaka zana.Mu
Njira yachitukuko cha zaka zana izi, ikhoza kugawidwa m'magulu angapo ofunikira nthawi. Pambuyo pa 1930, ukadaulo wazitsulo wa ufa unakula kwambiri, ndipo diamondi idayamba kusakanizidwa ndi ufa wachitsulo, ndikugwiritsa ntchito zitsulo za ufa kupanga mutu wa mpeni, ndiye welded pa gawo lapansi, amene anali prototype oyambirira amakono macheka tsamba.Mu 1955, kubadwa kwa diamondi yokumba kulimbikitsa kwambiri chitukuko cha makampani diamondi chida.Ndi kupita patsogolo kosalekeza kwaukadaulo wa diamondi wochita kupanga, diamondi yokumba pang'onopang'ono idalowa m'malo mwa diamondi yachilengedwe yodula, zomwe zidapangitsa kuti tsamba lalikulu la diamondi litheke.Pakalipano, tchipisi ta diamondi zimagwiritsidwa ntchito kwambiri podula zinthu zolimba komanso zowonongeka, kuphatikizapo miyala ya granite ndi zipangizo zina zamwala,

galasi, zinthu za ceramic, semiconductors, miyala yamtengo wapatali, chitsulo chosungunuka, ndi zinthu za konkire m'misewu ndi Bridges.Ndi kukula kosalekeza ndi kuwongolera kwa diamondi
ukadaulo wa tsamba, ntchito yake idzakhala yotakata, tsamba la diamondi lakhala nalo
kukhala chida cha diamondi chowononga kwambiri [4,5].
China ili ndi zinthu zambiri zamwala, ndikutukuka kwachuma, kugwiritsidwa ntchito kwa miyala kukukulirakulira, zomwe zimapangitsa kuti msika ukhale wofunikira kwambiri wa zida za diamondi.Malinga ndi China Market Research Center
(mpaka 2010), monga momwe tawonetsera pa Chithunzi 1.1.Kugulitsa kwa diamondi ku China kudakwera kwambiri pakati pa 2003 ndi 2008, ndikuwonjezeka pafupifupi 15%.Mu 2009 ndi 2010, malonda adatsika pang'ono, koma kuchuluka kwa msika kunasintha kufika pa 18 biliyoni.Kuphatikizidwa ndi zomwe zidagulitsidwa m'mbuyomu za diamondi zazaka zisanu ndi zitatu komanso chitukuko cha zachuma padziko lonse lapansi, bungwe lofufuza lidaneneratu za kufunikira kwa msika wa diamondi kuyambira 2011 mpaka 2015 (manenedwe a 2010) monga zikuwonetsedwa pa Chithunzi 1.2.

Chithunzi 1.1 Kusintha kwa macheka a diamondi m'zaka zaposachedwa: yuan miliyoni 100

Chithunzi 1.2 Chigawo chofuna msika cha tsamba la diamondi ndi gawo lake ku China kuyambira 2011 mpaka 2015: Chigawo cha zidutswa 100 miliyoni
Malinga ndi tchati cholosera cha China Market Research Center, ndikukula kosalekeza kwa tsamba la diamondi, kufunikira kwa msika waku China kwa tsamba la diamondi ndi gawo lapansi lidzakwerabe pafupifupi 15% pachaka mtsogolomo.Zikuyembekezeka kuti kufunika kwa tsamba la diamondi ndi gawo lapansi ku China kudzafika zidutswa biliyoni 3.201 pofika chaka cha 2015. Poyang'anizana ndi kufunikira kwakukulu kwa msika, kwa wopanga tsamba la diamondi iliyonse ndi mwayi komanso zovuta.Kupanga kokha kwamphamvu kwambiri, moyo wautali wautumiki, magwiridwe antchito okhazikika, ntchito yotsika mtengo ya tsamba la diamondi, kuti mutenge msika posachedwa, gwiritsani ntchito mwayiwo.
