Kev Nyiaj: daim ntawv thov, cov khoom thiab cov ntaub ntawv nqi

Nyob rau tus neeg ua lag luam, cov nyiaj belongs rau lub chav kawm ntawv ntawm precious hlau, tab sis nyob rau hauv nws cov ntshiab daim ntawv nws yog feem ntau lug siv nyob rau hauv qhov kev lag luam, kev muab cov kev kawm ntawv ntawm ntau yam hluav taws xob khoom siv.

Ntxiv mus, nws tau yav tas los tau siv nyob rau hauv cov creation ntawm photographic thiab tsom iav, ua tsaug rau ib paab nto. Tab sis tsis txhob xav yuam kev rau qhov no nrog ib tug hlau jewellery alloys - qhov txawv nruab nrab ntawm lawv yog heev tseem ceeb, thiab nws tsis yog cia li ib lo lus nug ntawm nqi.

Yuav ua li cas yog cov kev nyiaj

Txawm tias nws lub npe, hinting ntawm shoddy khoom, ntshiab nyiaj 999 yog muab zais nyob rau hauv no lub sij hawm, nrog rau qhov sib ntxiv ntawm tooj liab hlau los yog cermet composites.

Nws yog muab rho tawm los ntawm cov hmoov txhuas ores thiab feem ntau tsis zoo ib yam nkaus thiab txaus.

Ligatures, ntxiv rau cov kev nyiaj, muaj ib tug ncaj qha txhais muaj pes tsawg leeg. Nws yog xaiv nyob rau hauv raws li cov kev kawm cheeb tsam ntawm daim ntawv thov cov ntaub ntawv kho nyob rau hauv cov tshuaj thiab lub cev thaj chaw ntawm cov hlau thiab yog feem ntau tsim los kom cov hluav taws xob conductivity los yog lub dag lub zog neeg.

Nyob rau hauv lub chaw ua khoom ntawm hniav nyiaj hniav kub siv txawv lig impurity imparting khoom ntau txaus nyiam tsos thiab ductility, thiab cov uas tseem hais ib tug tsawg dua tus nqi kev alloy.

hlau zog

Kev nyiaj muaj ib daim ntawv teev ntawm lub cev zoo uas tso cai rau nws siv nyob rau hauv lub electronics teb rau qhov siv thiab ua ntau qhov chaw. Ib txhia ntawm cov yam ntxwv xws li tsis xws li:

• Tsis tshua muaj melting kub;
• ib theem siab ntawm thermal thiab hluav taws xob conductivity;
• softness thiab yooj ntawm cov khoom;
• inert (passive rau txhoj puab heev reagents);
• zoo teeb reflectivity ntawm;
• xeb kuj;
• txhua yam muaj zog.

Txawm li cas los, cov hniav nyiaj hniav kub hlau muaj ib tug ntau dua tus nqi tshaj kev nyiaj. Nqe ib 1 gram ntawm cov hlau yuav sawv vim yog lub kim tshem tawm ntawm cov hlau lead uas yog txaus ntshai rau tib neeg noj qab haus huv vim hais tias ntawm cov nyiam noog nyob rau hauv cov ntaub so ntswg ntawm lub cev. Txawm li cas los, cov xov tooj cua yog ua si ib tug me nyuam lub luag hauj lwm, vim hais tias tsis cuam tshuam rau cov muag khoom ntawm cov khoom.

daim ntawv sau npe

Ua ntej ntawm tag nrho cov, nws yuav tsum tau muab sau tseg hais tias kev nyiaj yuav tau los ntawm recycling apparatus muaj ib tug zoo zoo nkauj tshooj hlau ib feem. Nyob rau hauv cov ntaub ntawv no, tom qab tshem tawm ntawm lub remelted seem cov ntaub ntawv uas muaj pes tsawg leeg yog tsis amenable mus standardization thiab xa mus rau lub refinery rau xaiv, txwv tsis pub tau nws ntxiv siv yog tshem tawm.

Ntshiab nyiaj thiab tswj los ntawm GOST compositions yog siv nyob rau hauv cov nram no industries:

• electronics;
• khoom noj khoom haus kev lag luam (ntau lawm ntawm cov khoom rau cia);
• Tshuaj thiab kev kho hniav;
• huab cua thiab foob pob ua ntxaij science.

Nws yuav tsum tau muab sau tseg tias kev silver (nqi rau 1 gram yog ib co nyob rau ntawm lub alloy) yog siv nyob rau hauv txhua industrial cov nplais, thiab kev txoj kev tau ua lub ntsiab txoj kev uas yuav muab tau nws.

Qhov twg nyiaj nyob

Niaj hnub no kawm tau los ntawm cov khoom thiab muag cov nyiaj daim muaj cai rau ib yam ntawm nws tus tswv. Feem ntau cov kev nyab xeeb, nyob rau ntawm no point, tus laus tus qauv yuav mechanisms xws li electromagnetic actuators: lawv yog cov soldering ntawm lub precious hlau.

Khoom tsis muaj impurities pom nyob rau hauv ntau hom ntawm relays, lub thermode (silver hlau), cov kabmob AI-roj teeb thiab cov hlau.

Nyob rau hauv heev me me qhov ntau tej zaum yuav muaj nyob rau hauv aircraft thaiv thiab connectors.

Yuav kom tau soj ntsuam xyuas cov authenticity ntawm hlau, coob leej ntau tus ib tug sib tov ntawm nitric acid thiab poov tshuaj dichromate: yog tias nyiaj tam sim no soaked muaj pes tsawg leeg qhov chaw tau liab.

hlau muag khoom thiab nws tus nqi

Nyob rau hauv internet los yog nyob rau hauv lub xov tooj cua, koj yuav muag ib tug kev nyiaj. Nqe ib tug kab yuav sib txawv nyob ntawm seb ob yam tseem ceeb:

1. Kuaj t. E. Qhov feem pua ntawm cov hlau.
2. kev muag khoom qhov chaw, raws li txhua buyer txo nws hwj tus nqi rau nws tus kheej kom zoo dua.

Cov neeg uas tsis tau yav tas los ntsib nrog cov kev soj ntsuam ntawm kev coj dawb huv ntawm cov hlau, nws yog zoo dua siv cov kev pab ntawm cov tub txawg los yog kam rau ntawm qhov chaw. Txawm li cas los, cov kev xaiv thawj yuav muab ntau dua cog qoob loo nyob rau hauv lub correctness ntawm cov nqi thiab txo txoj kev pheej hmoo ntawm muag ntawm ib tug txo nqi.

Thaum kev muag khoom ntawm seem hlau yog cov feem ntau nrov cutlery los yog cov khoom uas muaj ib tug silver-plated, raws li lawv muaj lub siab txaus qauv. Nyob rau hauv txhua rooj plaub, ntau npaum li cas txiaj ntsim ua kom qhov muag los ntawm online auctions los yog thematic forums - nyob rau Internet feem ntau yog buyers kam muab ib tug ntau dua tus nqi.

Cov neeg uas xav paub ntau npaum li cas cov kev nyiaj, nqi ib tug los ze zog saib ntau yam muab thiab xaiv ib tug uas raws li lawv cov uas yuav tsum tau. Nyob rau hauv dav dav, lub nqi ntawm 1 gram yog los ntawm hais txog 20 mus rau 32 rubles; no sib txawv yog ncaj qha mus txog rau qhov feem pua ntawm cov ntshiab precious hlau nyob rau hauv lub hlau los yog unserviceable khoom.
