Iko kushandiswa uye chimiro chedhaimani zvishandiso.

Nekuvandudzwa kwehupfumi hwenyika pamwe nekuvandudzwa kwemararamiro evanhu, matombo echisikigo (granite, marble), jade, dombo rekugadzira regiredhi repamusoro (microcrystalline stone), ceramics, girazi, uye simende zvigadzirwa zvakashandiswa zvakanyanya mudzimba nezvivakwa. .Iko kushongedza kwezvinhu kunoshandiswa mukugadzirwa kwezvishongedzo zvakasiyana-siyana, muzvinodiwa zvezuva nezuva uye mukugadzirwa kwemigwagwa nemabhiriji.

Kugadziriswa kwezvinhu izvi kunoda zvakasiyana-siyana zvemadhaimondi zvishandiso.

Maturusi edhaimani anogadzirwa muGermany, Italy, Japan, neSouth Korea ane marudzi akawanda, emhando yepamusoro uye mitengo yakakwira.Zvigadzirwa zvavo zvinenge zvichitora yakawanda yemusika wepamusoro wekugadzira matombo.

Mumakore gumi apfuura kana kupfuura, makambani ekuChina anogadzira maturusi edhaimani akakura nekukurumidza.Kubva pakuona kwehuwandu hwemakambani, kune makambani anoda kusvika chiuru anogadzira maturusi edhaimondi, nemari yekutengesa pagore inodarika makumi emabhiriyoni.Kune vangangoita zana vanogadzira maturusi edhaimani muDanyang City mudunhu reJiangsu, Shijiazhuang Guta mudunhu reHebei, Ezhou Guta mudunhu reHubei, Shuitou Guta muQuanzhou Guta mudunhu reFujian, Yunfu Guta muGuangdong Province uye Shandong Province.Kune akawanda uye akakura mabhizinesi anogadzira maturusi edhaimondi muChina, ayo asingaenzaniswi nedzimwe nyika pasirese, uye zvirokwazvo ichave iyo pasi rose maturusi ekushandisa.Dzimwe mhando dzematurusi edhaimondi muChina zvakare dzine huwandu hwemhando yepamusoro, uye mamwe mabhureki ane mukurumbira emidziyo yedhaimondi kune dzimwe nyika akarairawo makambani ekuChina kuti aagadzire.Nekudaro, zvizhinji zvezvigadzirwa zvinogadzirwa nemakambani mazhinji ndeemhando yakaderera uye mutengo wakaderera.Kunyangwe China ichitengesa kunze nhamba huru yemidziyo yedhaimondi, mazhinji acho zvigadzirwa zvemutengo wakaderera uye anonzi "junk".Kunyangwe zvigadzirwa zvemhando yepamusoro zvinosangana kana kupfuura zvigadzirwa zvekunze zvakafanana, nekuti zvinogadzirwa muChina, hazvigone kutengesa nemutengo wakanaka, izvo zvinokanganisa zvakanyanya mufananidzo weChina.Chii chinokonzera mamiriro ezvinhu aya?Muchidimbu, pane zvikonzero zvikuru zviviri.

Imwe ndiyo yakaderera mwero wehunyanzvi.Iko kuvandudza tekinoroji yekugadzira madhaimondi inogona kukamurwa kuita matanho matatu kusvika zvino.Nhanho yekutanga ndeye kushandisa elemental poda sematrix uye kuwedzera madhaimondi kugadzira maturusi edhaimani nemaitiro ekusanganisa mechaniki.Iyi nzira inotarisana nekuparadzaniswa kwechikamu;yakakwirira sintering tembiricha inogona nyore kukonzera diamond graphitization uye kuderedza simba redhaimani.Sezvo zvinhu zvakasiyana-siyana zvezvitunha zvakabatanidzwa nemichina, hazvina kusanganiswa zvakakwana, uye chitunha chine mhedzisiro yakaipa pamadhaimondi, zvichiita kuti zviome kugadzira zvigadzirwa zvepamusoro.Nhanho yechipiri ndeyekushandiswa kwepre-alloyed poda sematrix uye maitiro ekusanganisa madhaimani kugadzira maturusi edhaimondi.Nekuti iyo matrix zvinhu zvakasanganiswa zvizere uye tembiricha yekupisa yakadzikira, kuita uku hakuzodzikisire simba redhaimani, kudzivirira kupatsanurwa kwezvikamu, kuburitsa yakanaka encasement mhedzisiro padhaimani, uye kuita kuti dhaimondi ritambe zvakanaka.Maturusi edhaimondi anogadzirwa nekushandisa pre-alloyed poda sezvo matrix ane hunhu hwepamusoro uye inononoka kunonoka, uye inogona kugadzira emhando yepamusoro maturusi edhaimani.Danho rechitatu kushandisa pre-alloyed poda sematrix, uye kurongeka kwakarongeka (multi-layer, uniformly distributed diamond) tekinoroji yemadhaimondi.Iyi tekinoroji ine zvakanakira zvehunyanzvi zve pre-alloyed poda, uye inoronga madhaimondi nenzira yakarongeka, kuitira kuti dhaimondi rega rega rishandiswe zvizere, uye rinokunda chikanganiso chekuti kugovaniswa kwemadhaimondi kunokonzerwa nekusanganiswa kwemichina kunokanganisa zvakanyanya kuita kwekucheka. ., Ndiyo tekinoroji yazvino mukugadzirwa kwemidziyo yedhaimani munyika nhasi.Tora iyo inowanzo shandiswa ?350mm diamond yekucheka blade semuenzaniso, kugona kwekucheka kwekutanga tekinoroji ndeye 2.0m (100%), kugona kwekucheka kwechikamu chechipiri tekinoroji 3.6m (yakawedzera kusvika 180%), uye yechitatu. nhanho Kushanda kwekucheka kwehunyanzvi ndeye 5.5m (yakawedzera kusvika 275%).Pakati pemakambani ari kugadzira maturusi emadhaimani pari zvino kuChina, 90% achiri kushandisa michina yedanho rekutanga, asingasviki gumi kubva muzana emakambani anoshandisa tekinoroji yedanho rechipiri, uye makambani ega ega anoshandisa tekinoroji yedanho rechitatu.Hazvina kuoma kuona kuti pakati pemakambani ekushandisa madhaimondi aripo muChina, makambani mashoma anokwanisa zvizere kugadzira zvigadzirwa zvemhando yepamusoro.Nekudaro, makambani mazhinji achiri kushandisa zvechinyakare uye kumashure tekinoroji.

Yechipiri makwikwi ane utsinye.Maturusi edhaimani anodyiwa uye ari kudiwa zvikuru pamusika.Zvinoenderana neazvino tekinoroji yekugadzira maturusi edhaimani padanho rekutanga, zviri nyore kutanga bhizinesi idzva remadhaimani.Munguva pfupi, kune makambani anoda kusvika chiuru anogadzira maturusi edhaimondi muChina.Tora inowanzo shandiswa 105mm diamond saha blade semuenzaniso, chigadzirwa giredhi is'high-quality', ex-factory mutengo uri pamusoro 18 yuan, accounting pamusoro 10%;giredhi yechigadzirwa is'standard', mutengo wekare wefekitari ungangoita 12 yuan, uchiverengera 50%;Chigadzirwa giredhi "economic", mutengo wekare wefekitari ungangoita 8 yuan, uchiverengera 40%.Aya marudzi matatu ezvigadzirwa anoverengerwa zvichienderana neavhareji mari yemagariro.Iyo purofiti muganho we'yemhando yepamusoro' zvigadzirwa inogona kusvika kupfuura 30%, uye purofiti yemuchero ye'standard' zvigadzirwa inogona kusvika 5-10%.Iwo ekare-fekitari mitengo yemabhizinesi ese ari pasi pe8 yuan, uye kune akadzikira sepasi pe4 yuan.

Sezvo mazhinji emakambani tekinoroji ari padanho rekutanga, uye mhando yechigadzirwa yakafanana, kutora chikamu chemusika, vanofanirwa kurwira zviwanikwa nemitengo.Iwe unondibata, uye mitengo yechigadzirwa inodzikiswa.Zvigadzirwa zvakadaro zvinotengeswa kunze kwenyika zvakawanda.Ndosaka vamwe vachiti zvigadzirwa zveChinese 'junk'.Pasina kuchinja mamiriro ezvinhu aya, zvakaoma kudzivirira kusawirirana kwekutengeserana.Panguva imwecheteyo, makambani anogadzira zvigadzirwa zvemitengo yakaderera ari kutarisanawo nedambudziko rekutenda kweRMB.

Tora mugwagwa wemhando yepamusoro, kushanda zvakanaka kwepamusoro, kuchengetedza simba uye kuderedza emission.

Kugadzirwa kwepagore kweChina nekutengesa makumi emabhiriyoni emayuan emidziyo yedhaimondi inoshandisa matani zviuru zana zvesimbi, simbi dzisina-ferrous, 400 miriyoni magiramu emadhaimondi, 600 miriyoni kWh yemagetsi, 110,000 matani emidziyo yekurongedza, 52,000 matani emavhiri ekukuya, uye matani 3,500 ependi.Zvigadzirwa zvinogadzirwa zvino zvakanyanya zvepakati uye zvakaderera-zvekupedzisira.Zvichienzaniswa nezvigadzirwa zvenyika dzakabudirira, pane mukaha mukuru.Semuenzaniso, 105mm diamond saw blade, inoenderera yakaoma yakaoma 20mm gobvu yepakati-yakaoma giraniti slab, yakacheka 40m kureba.Iko kushanda kwekucheka kwezvigadzirwa munyika dzakabudirira kunogona kusvika 1.0 ~ 1.2m paminiti.China's'standard' zvimedu zvinogona kutemwa 40m kureba pasina simba, uye kushanda kwezvigadzirwa zvakanaka zvinogona kusvika 0.5 ~ 0.6m paminiti, uye iyo'economic' zvimedu zvinogona kutemwa zvisingasviki 40m ini handichakwanise kuzvifambisa, paavhareji. kunyatsoshanda paminiti iri pazasi 0.3m.Uye mashoma edu "yemhando yepamusoro" zvidimbu, iyo yekucheka inoshanda inogona kusvika 1.0 ~ 1.5m paminiti.China yava kukwanisa kugadzira maturusi edhaimani emhando yepamusoro.Zvigadzirwa zvemhando yepamusoro zvine hunyanzvi hwekucheka uye zvinogona kuchengetedza simba rakawanda nemaawa emunhu kana zvichishandiswa.Zvigadzirwa zvemhando yepamusoro zvinogona kushandiswa uye zvine hupenyu hurefu hwebasa.Imwe "yepamusoro-soro" saw blade inogona kumusoro 3 kusvika 4 "standard" kana "economic" blades.Kana madhaimondi akaona mashizha anogadzirwa muChina achidzorwa pamwero we'yepamusoro-mhando' mapanga, gore rimwe rekutengesa mari inongowedzera, kwete kuderera, uye ingangoita 50% yezviwanikwa zvinogona kuponeswa (simbi, isiri-ferrous simbi 50,000. matani, magetsi 300 miriyoni Dhigirii, 55 000 matani ezvokurongedza, matani 26,000 emavhiri ekukuya, uye matani 1,750 ependi).Inogona zvakare kuderedza kubuda kweguruva kubva mugumbo rekukuya uye kubuda kwependi gasi, uye kuderedza kusvibiswa kune zvakatipoteredza.
