1. Cov khoom siv kub-hloov: Nws yuav siv cov lo lo ntxhuav kub ua lub hauv paus, thiab nws qhov chaw yog them nrog txheej qhib (K) kub.Muaj ob xim qhib kub: dawb kub thiab daj kub.
A. kub
Qhov no yog cov hlau kub uas zoo ductility thiab yuav luag tsis muaj oxidative discoloration.Txij li cov kub ntshiab (24K) yog mos heev, thaum siv kub los ua ib qho spectacle ncej.Nws yog tov nrog additives xws li hlau thiab nyiaj ua rau nws mus rau hauv ib tug alloy kom txo tau cov qib thiab nce lub zog thiab toughness.Cov ntsiab lus kub ntawm cov tsom iav feem ntau yog 18K, 14K, 12K, loK.
B platinum
Qhov no yog cov hlau dawb, hnyav thiab kim, nrog purity ntawm 95%.
2. Qhib kub thiab pob kub
A. Qhov qhib kub yog dab tsi?Qhov hu ua (K) kub tsis yog kub ntshiab, tab sis ib qho hlau ua los ntawm cov kub ntshiab thiab lwm yam hlau.Cov kub ntshiab yog kub uas tsis tau ua tiav tag nrho (uas yog, tsis suav nrog lwm yam hlau).Cov kub qhib siv hauv kev lag luam yog hais txog qhov sib piv ntawm cov kub ntshiab rau lwm cov hlau hauv cov hlau, qhia hauv (K) tus lej, uas tau qhia tias yog ntau yam ntawm ib feem plaub ntawm tag nrho qhov hnyav ntawm kub, yog li 24K kub yog ntshiab kub. .12K kub yog cov hlau uas muaj kaum ob feem ntawm cov kub ntshiab thiab kaum ob qhov ntawm lwm cov hlau, thiab 9K kub yog cov hlau uas muaj cuaj qhov ntawm cov kub ntshiab thiab kaum tsib feem ntawm lwm cov hlau.
B. Gild
Kub-clad yog lub ntsiab lus zoo.Hauv kev tsim cov kub-clad, ib txheej ntawm lub hauv paus hlau yog qhwv nrog ib txheej ntawm qhib kub, thiab cov ntaub ntawv kawg specification yog qhov piv ntawm qhib kub siv thiab tus naj npawb ntawm qhib kub.
Muaj ob txoj hauv kev los qhia cov txheej kub: ib feem kaum ntawm 12 (K) txhais tau tias ib feem kaum ntawm qhov hnyav ntawm tus ncej yog 12K kub;lwm qhov yog qhia los ntawm tus nqi ntawm cov kub ntshiab uas muaj nyob rau hauv cov khoom tiav;ib feem kaum 12K kub tuaj yeem sau ua 5/100 dawb huv (vim 12K kub muaj 50/100 dawb huv).Ib yam li ntawd, ib tug nees nkaum 10K kub tuaj yeem sau ua 21 / looo dawb huv.Los ntawm kev sib piv, ob qho tib si daj kub thiab dawb tuaj yeem siv los ua kub-clad thav duab.
3. Cov khoom siv tooj liab
Cov tooj liab tseem ceeb tshaj plaws yog tooj dag, bronze, zinc cupronickel, thiab lwm yam, thiab tooj dag thiab cupronickel feem ntau siv hauv kev lag luam tsom iav.
A. tooj liab nickel zinc alloy (zinc cupronickel)
Vim nws zoo machinability (machinability, electroplating, thiab lwm yam), nws tuaj yeem siv rau txhua qhov chaw.Nws yog ternary alloy uas muaj Cu64, Ni18, thiab Znl8.
B. tooj dag
Nws yog binary alloy uas muaj cu63-65% thiab tus so yog zn, nrog cov xim daj.Qhov tsis zoo yog tias nws yooj yim hloov xim, tab sis vim tias cov nti yog ib qho yooj yim rau kev ua, nws tuaj yeem siv los ua cov ntaub qhwv qhov ntswg.
C. Copper nickel zinc tin alloy (Bran Kas)
Nyob rau hauv no quaternary alloy uas muaj Cu62, Ni23, zn1 3, thiab Sn2, nws yuav siv tau rau ntug txhob lo lo ntxhuav thiab luam ntawv Hoobkas-zoo li tus cim vim nws zoo elasticity, electroplating zog thiab zoo heev corrosion kuj.
D. Bronze
Qhov no yog ib qho alloy ntawm Cu thiab sn alloys nrog cov khoom sib txawv raws li qhov kev faib ua feem ntawm sn muaj.Piv nrog rau tooj dag, vim hais tias nws muaj tin sn, nws yog kim thiab nyuaj rau txheej txheem, tab sis vim nws cov elasticity zoo heev, nws yog haum rau ntug hlau cov ntaub ntawv, thiab qhov tsis zoo yog tias nws tsis yog corrosion resistant.
E. High-strength corrosion-resistant nickel-tooj liab alloy
Qhov no yog ib qho alloy uas muaj Ni67, CU28, Fc2Mnl, thiab 5i.Cov xim yog xim dub thiab dawb, muaj zog corrosion kuj thiab tsis zoo elasticity.Nws yog haum rau lub nplhaib ntawm tus ncej.
Yuav luag tag nrho cov saum toj no tsib tooj liab alloys yuav siv tau raws li cov primer rau kub-plating cov ntaub ntawv thiab cov primer rau electroplating nyob rau hauv spectacle thav ntawv ua nyob rau hauv tsev thiab txawv teb chaws.
4.Stainless hlau
Qhov no yog cov hlau uas muaj Fe, Cr, thiab Ni.Zoo corrosion kuj, nrog cov yam ntxwv sib txawv nrog cov additives sib txawv.High elasticity, siv los ua cov tuam tsev thiab cov ntsia hlau.
5. Nyiaj
Cov thav duab qub heev yog ua los ntawm cov nyiaj alloy.Tsuas yog cov tsom iav ntev ntev txawv teb chaws thiab qee cov iav clip-on zoo nkauj tseem siv los ua cov khoom siv niaj hnub no.
6. Anodized txhuas
Cov khoom siv yog lub teeb, corrosion-resistant, thiab txheej txheej ntawm alumina tuaj yeem ua rau cov khoom tawv tawv.Thiab nws tuaj yeem dyed rau hauv ntau qhov muag-catch xim.
7. Nyiaj npib tsib xee
Department ntawm tooj liab thiab npib tsib xee alloy, thiab ces ntxiv zinc bleaching.Nws ua rau lub ntsej muag nyiaj, yog li nws tseem hu ua "ntsuab nyiaj".Nws muaj zog, tiv taus corrosion, thiab pheej yig dua kub-clad.Yog li ntawd, nws tuaj yeem siv los ua tus menyuam tus ncej.Tom qab lub thav duab yog tsim, ntshiab nickel plating yog siv los ua kom lub ntsej muag ci dua.
8. Titanium (Ti)
Qhov no yog lub teeb yuag, kub-resistant, thiab corrosion-resistant hlau uas tau nyiam cov xim ntawm ntau yam lag luam.Qhov tsis zoo yog tias muaj ntau yam cuam tshuam rau qhov tsis ruaj khov ntawm lub tshuab ua haujlwm.
9. Rhodium plating
Electroplating rhodium ntawm cov xim daj kub, cov khoom tiav yog cov khoom siv kub dawb uas tsis yog xim hlau thiab cov khoom siv hluavtaws nrog kev ua haujlwm ruaj khov thiab zoo nkauj.
