Tsis tas li ntawd, npib tsib xee muaj qhov zoo tshaj plaws conductivity thiab thermal conductivity, uas ua rau nickel daim hlau irreplaceable nyob rau hauv cov khoom siv hluav taws xob thiab hluav taws xob.
1. Lub cev thiab tshuaj muaj zog
1) Cov tsos thiab kev ntxhib los mos: Cov phaj npib tsib xee nthuav tawm cov xim dawb dawb, muaj luster zoo, thiab tsis pom tseeb.
2) Qhov ceev thiab hardness: Nickel muaj qhov ceev ntawm 8.9 grams ib cubic centimeter thiab yog cais raws li ib tug nruab nrab hardness hlau.
3) Melting point thiab boiling point: Nickel muaj ib tug melting point ntawm 1455 degree thiab ib tug boiling point ntawm 2730 degree.
4) Magnetism thiab plasticity: Nickel yog hlau nrog hlau nplaum thiab yas zoo, ua kom yooj yim rau kev ua ntau yam duab.
5) Corrosion kuj: Nickel tsis yooj yim oxidized hauv huab cua thiab muaj kev tiv thaiv corrosion zoo heev thiab oxidation tsis kam. Nws tuaj yeem tiv taus qhov yaig ntawm ntau yam corrosive media, nrog rau cov kua qaub thiab alkaline daws. Tshwj xeeb, npib tsib xee muaj zog tiv thaiv corrosion rau caustic soda, nrog rau txhua xyoo corrosion tsis ntau tshaj 25 microns hauv 50% boiling caustic soda tov.
2. Lub hom phiaj tseem ceeb
1) Kev lag luam hlau: Nickel phaj yog ib qho tseem ceeb raw khoom rau kev tsim stainless hlau. Los ntawm kev ntxiv cov nyiaj npib tsib xee tsim nyog, qhov kev tiv thaiv corrosion thiab lub zog ntawm cov hlau tuaj yeem txhim kho tau zoo. Stainless hlau muaj ntau yam kev siv hauv kev lag luam xws li kev tsim kho, chav ua noj, thiab khoom siv kho mob.
2) Electroplating teb: Nickel phaj yog ib qho tseem ceeb raw khoom rau electroplating, thiab electroplated npib tsib xee txheej tuaj yeem muab cov txheej txheem tiv thaiv zoo, ua rau kev hnav tsis kam thiab zoo nkauj ntawm cov khoom. Piv txwv li, automotive Cheebtsam, hluav taws xob cov khoom casings, thiab lwm yam yuav undergone nickel plating kev kho mob.
3) Kev tsim roj teeb: Nickel ua lub luag haujlwm tseem ceeb hauv kev tsim cov roj teeb, tshwj xeeb tshaj yog nyob rau hauv cov roj teeb nickel hydrogen thiab lithium-ion roj teeb, uas cov nickel pab txhim kho cov roj teeb kev ua haujlwm thiab kev ua neej nyob.
4) Aerospace: Vim nws lub zog siab thiab corrosion tsis kam, nickel daim hlau kuj tseem muaj cov ntawv thov tseem ceeb hauv thaj chaw aerospace, xws li kev tsim cov cav tov, cov khoom siv hauv lub dav hlau, thiab lwm yam.
5) Lwm daim ntawv thov kev lag luam: Nickel daim hlau kuj tseem siv los tsim cov hlau, txhim kho cov neeg kho tshuab lub zog thiab corrosion kuj. Piv txwv li, cov alloys uas muaj npib tsib xee tuaj yeem siv los tsim cov khoom ntawm cov tshuab uas tuaj yeem tiv taus siab, cuam tshuam, thiab cov khoom siv rov ua haujlwm, xws li turbine blades, crankshafts, txuas rods, thiab lwm yam. Tsis tas li ntawd, cov phaj nickel kuj tseem siv los tsim cov chaw ua haujlwm. xws li roj tank tsheb footrests, tshuab hnyav thiab boilers, escalators, taug kev, thiab lwm yam.
3. Kev tsim khoom thiab kev tsim khoom
1) Melting casting txoj kev: Nickel daim hlau yog tau los ntawm melting nickel alloys rau hauv billets thiab ces dov thiab ncab lawv.
2) Electrolytic deposition method: Electrolyze ib nickel ntsev tov, tso npib tsib xee rau ntawm electrode, thiab tom qab ntawd ntxuav thiab ua cov nickel phaj.
3) hmoov metallurgy txoj kev: Nickel daim hlau yog tau los ntawm nias hmoov rau hauv billets, ua raws li sintering thiab dov txheej txheem.
4. Ua raws li cov qauv thiab cov lus qhia tshwj xeeb
Cov qauv tsim khoom rau cov phaj nickel suav nrog GB/T{{0}} thiab GB/T2054-2005. Nws cov kev qhia tshwj xeeb thiab cov qauv muaj ntau haiv neeg, nrog cov tuab tuab ntawm 0.5-20 millimeters, qhov dav ntawm 200-1000 millimeters, thiab qhov ntev ntawm 500-3000 millimeters. Tsis tas li ntawd, daim hlau npib tsib xee kuj tuaj yeem kho tau rau kev tsim khoom raws li cov neeg siv khoom xav tau.
Nickel daim hlau tau nyiam ntau xim vim lawv lub cev zoo thiab tshuaj lom neeg thiab ntau yam kev siv. Thaum xaiv cov nickel daim hlau, yam xws li lawv cov kev siv, kev qhia tshwj xeeb, cov qauv kev ua tiav, thiab cov txheej txheem tsim khoom yuav tsum raug txiav txim siab los xyuas kom meej tias cov khoom uas ua tau raws li cov kev cai raug xaiv.
