1. Zvinhu zvakanatsiridzwa negoridhe: Zvinoda sirika yegoridhe sehwaro, uye pamusoro payo pakafukidzwa nejira regoridhe rakavhurika (K).Kune mavara maviri egoridhe rakavhurika: goridhe chena uye yero goridhe.
A. goridhe
Iyi isimbi yegoridhe ine yakanaka ductility uye inenge isina oxidative discoloration.Sezvo goridhe rakanatswa (24K) rakapfava kwazvo, kana uchishandisa goridhe semucherechedzo furemu.Inosanganiswa nezvinowedzerwa sesimbi uye sirivheri kuti iite alloy kuderedza giredhi uye kuwedzera simba uye kuoma.Iyo yegoridhe yemukati yezviratidziro mafuremu inowanzo 18K, 14K, 12K, loK.
B platinum
Iyi isimbi chena, inorema uye inodhura, ine kuchena kwe95%.
2. Vhura goridhe uye pasuru yegoridhe
A. Chii chinonzi goridhe rakavhurika?Iyo inodaidzwa kuti (K) goridhe haisi goridhe chairo, asi alloy yakagadzirwa negoridhe rakanatswa nemamwe masimbi.Ndarama yakachena igoridhe risina kunyatsobatanidzwa (ndiko kuti, risina kuiswa mune dzimwe simbi).Goridhe rakavhurika rinoshandiswa mubhizinesi rinoreva chiyero chegoridhe rakanatswa kune mamwe simbi mune alloy, inotsanangurwa mu (K) manhamba, iyo inotaridzwa seyakapetwa chikamu chimwe muzvina chehuremu hwakazara hwegoridhe, saka 24K goridhe iGoridhe rakachena. .12K goridhe ndiyo alloy ine zvikamu gumi nezviviri zvegoridhe rakachena uye zvikamu gumi nembiri zvezvimwe simbi, uye 9K goridhe ndiro yakasanganiswa ine zvikamu zvipfumbamwe zvegoridhe rakachena uye gumi neshanu zvikamu zveimwe simbi.
B. Gild
Ndarama-yakapfeka ndiyo chirevo chehutano.Mukugadzirwa kwegoridhe-yakavharwa, imwe dhizaini yesimbi yepasi inoputirwa negadzi regoridhe rakavhurika, uye yekupedzisira dhizaini chiyero chegoridhe rakavhurika rinoshandiswa uye nhamba yegoridhe rakavhurika.
Pane nzira mbiri dzekutaura kunama kwegoridhe: chikamu chimwe mugumi che12 (K) zvinoreva kuti chikamu chimwe mugumi chehuremu hwefuremu i12K yegoridhe;imwe yacho inoratidzirwa nehuwandu hwendarama chaiyo iri muchigadzirwa chakapedzwa;chikamu chimwe mugumi 12K goridhe inogona kunyorwa se5/100 goridhe rakachena (nekuti 12K goridhe rine 50/100 goridhe rakanatswa).Saizvozvo, makumi maviri nerimwe 10K goridhe rinogona kunyorwa se 21/looo goridhe rakachena.Nekuenzanisa, zvese zviri zviviri goridhe yero nechena zvinogona kushandiswa kugadzira mafuremu ane goridhe.
3. Copper alloy zvinhu
Iyo inonyanya kukosha yemhangura alloys ndeyendarira, ndarira, zinc cupronickel, nezvimwewo, uye ndarira uye cupronickel inowanzoshandiswa muindasitiri yemagirazi.
A. Copper nickel zinc alloy (zingi cupronickel)
Nekuda kwekunaka kwayo machinability (machinability, electroplating, nezvimwewo), inogona kushandiswa kune ese zvikamu.Iyo ternary alloy ine Cu64, Ni18, uye Znl8.
B. Brass
Iyo ibhinari alloy ine cu63-65% uye yasara zn, ine yero hue.Izvo zvisingabatsiri ndezvekuti zviri nyore kuchinja ruvara, asi nokuti chip iri nyore kugadzirisa, inogona kushandiswa kugadzira mapepa emhino.
C. Copper nickel zinc tin alloy (Bran Kas)
Mune ino quaternary alloy ine Cu62, Ni23, zn1 3, uye Sn2, inogona kushandiswa kumucheto silika uye kudhinda fekitori-yakaita zviratidzo nekuda kwekunaka kwayo, electroplating zvimiro uye yakanakisa corrosion kuramba.
D. Bronze
Iyi alloy yeCu uye sn alloys ane akasiyana zvivakwa zvinoenderana nechikamu che sn chirimo.Kana ichienzaniswa nendarira, nekuti ine tin sn, inodhura uye yakanyanya kuoma kugadzirisa, asi nekuda kwekunaka kwayo, inokodzera kumucheto waya waya, uye chakashata ndechekuti haina corrosion inodzivirira.
E. High-simba rinodzivirira nickel-copper alloy
Iyi alloy ine Ni67, CU28, Fc2Mnl, uye 5i.Ruvara rwakasviba uye ruchena, ruine corrosion resistance uye husina kunaka.Inokodzera mhete yefuremu.
Anenge ese ari pamusoro apa mashanu emhangura alloys anogona kushandiswa seyekutanga yegoridhe-plating zvinhu uye primer ye electroplating mumapepa ezviratidziro anogadzirwa kumba nekune dzimwe nyika.
4.Stainless Steel
Iyi alloy ine Fe, Cr, uye Ni.Good corrosion resistance, ine hunhu hwakasiyana hune siyana zvinowedzera.High elasticity, inoshandiswa setemberi uye screws.
5. Sirivha
Mafuremu echinyakare chaiwo anogadzirwa nesirivha alloy.Magirazi ekunze anobatika kwenguva refu uye mamwe magirazi ekushongedza-pamagirazi achiri kushandiswa semidziyo yemazuva ano.
6. Anodized aluminium
Izvo zvinhu zvakareruka, zvinodzivirira corrosion, uye iyo yekunze layer yealumina inogona kuwedzera kuoma kwezvinhu.Uye inogona kudhayiwa kuita mavara akasiyana-siyana anokwezva maziso.
7. Silver nickel
Dhipatimendi remhangura uye nickel alloy, uye wobva wawedzera zinc bleaching.Inoita kuti chitarisiko chesirivha, saka inonziwo "sirivha yekunze".Yakasimba, isingaite ngura, uye yakachipa pane yakapfeka goridhe.Nokudaro, inogona kushandiswa sefuremu yemwana.Mushure mekugadzirwa kwefuremu, nickel plating yakachena inoshandiswa kuita kuti chitarisiko chive chakajeka.
8.Titanium (Ti)
Iyi isimbi-inorema, isingapise kupisa, uye isingadziviriri simbi yakakwezva kutarisa kwemaindasitiri akasiyana.Izvo zvisingabatsiri ndezvokuti kune zvinhu zvakawanda zvinokanganisa kusagadzikana kwemashini.
9. Rhodium plating
Electroplating rhodium pane yero yegoridhe furemu, chigadzirwa chakapedzwa ndeye chena goridhe furemu isiri-yesimbi zvinhu uye yekugadzira zvinhu zvine kuita kwakagadzikana uye kutaridzika kunogutsa.
