Q: Vim li cas cov ntaub ntawv ntawm tus neeg xyuas pib thiab lub davhlau ya nyob twg txawv?
Tooj liab yog cov khoom siv dav siv ntau tshaj plaws. Nws muaj hluav taws xob zoo thiab thermal conductivity thiab tsis tshua muaj teeb liab kis tau tus mob attenuation. Txawm li cas los xij, lub davhlau ya nyob twg muaj qhov xav tau ntau dua li cov neeg siv hluav taws xob nyob rau hauv cov nqe lus ntawm oxidation tsis kam, corrosion kuj, thiab ntsaws tsis kam.
Q: Vim li cas thiaj xaiv kub plating tsis yog lwm yam hlau?
1. Antioxidant
Kub muaj zog antioxidant muaj peev xwm. Raws li kev hloov pauv hlau, nws thawj lub zog ionization yog siab li 890.1kJ / mol, thib ob tsuas yog cov mercury ntawm nws sab xis (1007.1kJ / mol), uas txhais tau hais tias oxygen yuav tsum tau muab los ntawm kub. Tau txais ib qho hluav taws xob yog qhov nyuaj heev. Tsis tsuas yog kub muaj zog ionization ntau dua li lwm cov hlau, tab sis vim nws 6s orbital muaj cov electrons tsis sib xws, nws cov atomization enthalpy kuj siab. Lub atomization enthalpy ntawm kub yog 368kJ / mol (mercury tsuas yog 64kJ / mol), uas txhais tau hais tias kub muaj Lub zog ntawm cov hlau binding quab yuam, muaj zog attraction ntawm kub atoms, nws tsis yog yooj yim rau exploited los ntawm lwm cov atoms.
2. Tiv thaiv corrosion
Kub yog cov hlau tsis zoo heev (qib kawg hauv daim ntawv teev npe hlau ua haujlwm), thiab feem ntau tsis muaj tshuaj lom nrog cov tshuaj corrosive xws li acids thiab alkalis, yog li nws tsis yooj yim rau corroded xws li oxidation thiab sulfidation.
3. Plug tsis kam
Ntxiv nrog rau cov txheej txheem tsim nyog thiab nruj, qhov kev ua tau zoo ntawm cov ntsaws ruaj ruaj yuav ua rau nws cov tawv tawv thiab hnav tsis kam tom qab kub plating, txo cov khoom poob thiab txuas ntxiv lub neej ntawm cov khoom.
Kub yog cov hlau tsis muaj zog, thiab nws nyuaj heev rau oxidize thiab hloov xim ntawm qhov kub thiab txias. Qhov siab dua qhov purity thiab thicker lub kub plating txheej, qhov nyuaj nws yog oxidize thiab zoo dua qhov zoo.
Yog tias koj lub davhlau ya nyob twg yog kub-plated thiab muaj cov tsos mob ntawm blackening tom qab ib lub sij hawm, koj muaj peev xwm dipped lub diluted detergent rau ntawm ib tug mos daim ntaub so ntswg so, thiab koj muaj peev xwm rov qab mus rau lub qub xeev. Txwv tsis pub, koj nyuam qhuav yuav ib tug copycat connector, los yog plated nrog hniav kub los yog lub purity ntawm kub tsis txaus, deb inferior rau tiag kub plating nyob rau hauv kev ua tau zoo thiab tus nqi.
