Ntshiab Sterling Silver AgCu7.5 Enamelled / Varnished Hlau rau Tsav Chev Daim Ntawv Thov

1. Cov ntaub ntawv qhia

Nyiajyog ib qho tshuaj lom neeg nrog lub cimAgthiab atomic tooj 47. Ib qho mos, dawb, ci ntsa iab hloov hlau, nws nthuav tawm cov hluav taws xob siab tshaj plaws, thermal conductivity, thiab kev cuam tshuam ntawm cov hlau. Cov hlau muaj nyob rau hauv lub ntiaj teb lub crust nyob rau hauv cov ntshiab, dawb elemental daim ntawv (" haiv neeg nyiaj"), raws li ib tug alloy nrog kub thiab lwm yam hlau, thiab nyob rau hauv minerals xws li argentite thiab chlorargyrite. Feem ntau cov nyiaj yog tsim los ntawm cov khoom siv tooj liab, kub, txhuas, thiab zinc refining.

Nyiaj tau ntev tau muaj nuj nqis raws li cov hlau muaj nuj nqis. Silver hlau yog siv nyob rau hauv ntau lub bullion npib, qee zaum nrog kub: thaum nws muaj ntau dua li kub, nws muaj ntau dua li cov hlau ib txwm muaj. Nws purity feem ntau yog ntsuas ntawm ib-mille hauv paus; a 94%-ntshiab alloy yog piav raws li "0.940 nplua". Raws li ib qho ntawm xya hlau ntawm ancient sij hawm, nyiaj muaj lub luag hauj lwm nyob rau hauv feem ntau tib neeg kab lis kev cai.

Tsis tas li ntawd nyob rau hauv txiaj thiab raws li ib tug peev nruab nrab (npib thiab bullion), nyiaj yog siv nyob rau hauv lub hnub ci vaj huam sib luag, dej pom, jewellery, ornaments, high-value tableware thiab cov tais diav (li no lub sij hawm silverware), nyob rau hauv hluav taws xob tiv tauj thiab conductors, tshwj xeeb. tsom iav, qhov rais txheej, hauv catalysis ntawm tshuaj tiv thaiv, raws li ib tug colorant nyob rau hauv stained iav thiab nyob rau hauv tshwj xeeb confectionery. Nws cov tebchaw yog siv nyob rau hauv kev yees duab thiab X-ray zaj duab xis. Dilute cov kev daws teeb meem ntawm cov nyiaj nitrate thiab lwm cov nyiaj sib txuas yog siv los ua cov tshuaj tua kab mob thiab microbiocides (oligodynamic effect), ntxiv rau cov ntaub qhwv thiab cov ntaub qhwv qhov txhab, catheters, thiab lwm yam khoom siv kho mob.

2. Rwb thaiv tsev piav qhia

Polyimide insulated hlau nplaum hlau muaj peev xwm ua haujlwm ntawm txog 250 ° C. Cov rwb thaiv tsev ntawm cov hlau nplaum tuab tuab los yog cov hlau nplaum hlau feem ntau yog augmented los ntawm kev qhwv nws nrog lub siab kub polyimide los yog fiberglass daim kab xev, thiab ua tiav windings feem ntau nqus impregnated nrog ib tug insulating kua roj vanish los txhim kho rwb thaiv tsev lub zog thiab lub sij hawm ntev kev cia siab ntawm lub winding.

Kev txhawb nqa tus kheej yog qhov txhab nrog hlau coated nrog tsawg kawg yog ob txheej, sab nraud yog cov thermoplastic uas khi cov lem ua ke thaum rhuab.

Lwm hom rwb thaiv tsev xws li fiberglass xov paj nrog cov kua roj vanish, aramid ntawv, kraft papaer, mica, thiabpolyesterzaj duab xis kuj tau dav siv thoob ntiaj teb rau ntau yam kev siv xws li transformers thiab reactors. Nyob rau hauv lub suab sector, ib tug hlau ntawm nyiaj siv, thiab ntau yam insulators, xws li paj rwb (qee zaum permeated nrog ib co coagulating tus neeg saib xyuas / thickener, xws li beeswax) thiab polytetrafluoroethylene (PTFE) tuaj yeem pom. Cov ntaub ntawv rwb thaiv tsev laus suav nrog paj rwb, ntawv, lossis lo lo ntxhuav, tab sis cov no tsuas yog siv tau rau cov ntawv thov kub (txog 105 ° C).

Rau kev yooj yim ntawm kev tsim khoom, qee qhov qis-kub-qib hlau nplaum hlau muaj rwb thaiv tsev uas tuaj yeem raug tshem tawm los ntawm tshav kub ntawm soldering. Qhov no txhais tau hais tias kev sib txuas hluav taws xob ntawm qhov kawg tuaj yeem ua tau yam tsis muaj stripping tawm ntawm lub rwb thaiv tsev ua ntej.
