Nqus npib tsib xee-plated, zinc-plated, chrome-plated nto hardness hnav-resistant thiab xeb-pov thawj

Nqus npib tsib xee-plated, zinc-plated, chrome-plated nto hardness hnav-resistant thiab xeb-pov thawj

a: Chrome plating feem ntau yog los txhim kho qhov tawv tawv, zoo nkauj tsos thiab tiv thaiv xeb. Chromium plating muaj tshuaj lom neeg ruaj khov thiab tsis ua rau alkali, sulfide, nitric acid thiab feem ntau cov organic acids, tab sis yog soluble hauv hydrohalic acid (xws li hydrochloric acid) thiab kub sulfuric acid. Vim tias chrome tsis hloov xim, nws tuaj yeem tswj tau nws lub peev xwm ua kom pom lub sijhawm ntev thiab zoo dua li nyiaj thiab npib tsib xee. Cov txheej txheem feem ntau yog electroplating.

b: Nickel plating feem ntau yog hnav-tiv taus, tiv thaiv corrosion, tiv thaiv xeb, feem ntau nyias, thiab cov txheej txheem muab faib ua ob pawg: electroplating thiab tshuaj lom neeg.

c: Galvanized feem ntau zoo nkauj thiab xeb-pov thawj. Zn yog cov hlau nquag uas tuaj yeem hnov ​​​​mob nrog cov kua qaub, yog li nws muaj kev tiv thaiv corrosion tsis zoo thiab yog qhov pheej yig tshaj ntawm peb.

Nqus nickel plating, zinc plating thiab chrome plating muaj qhov sib txawv

1) Lub hardness ntawm cov nickel txheej yog qhov siab, uas tuaj yeem txhim kho qhov hnav tsis kam ntawm cov khoom nto. Nickel plating feem ntau yog siv hauv kev lag luam luam ntawv los txhim kho cov tawv tawv ntawm cov hlau lead.

2) Txij li zinc tsis yooj yim rau kev hloov pauv hauv huab cua qhuav, hauv huab cua ntub, zinc carbonate zaj duab xis tuab tuaj yeem tsim rau saum npoo, uas tuaj yeem tiv thaiv sab hauv los ntawm corrosion. Txoj kev plating no yog tshwj xeeb tshaj yog tsim rau muaj zog corrosive ib puag ncig xws li ntau yam muaj zog acids thiab alkali pos huab.

3) chrome txheej yog nyias, ci thiab zoo nkauj. Nws feem ntau yog siv los ua txheej txheej txheej ntawm ntau txheej electroplating. Rau kev tiv thaiv lub hom phiaj, zinc-based lossis steel substrates yuav tsum tau plated nrog cov tuab txaus interlayer ua raws li 0.25-0.5 ci interlayer.

Nqus nickel plating, zinc plating, thiab chrome plating muaj kev siv sib txawv

1) Galvanizing yog siv rau hauv screws, Circuit Court breakers, industrial khoom, thiab lwm yam.

2) Nickel plating yog siv rau lub zog txuag lub kaus mom, npib, thiab lwm yam.

3) Chrome plating yog siv rau cov khoom siv zoo nkauj, faucets, thiab lwm yam ntawm cov khoom siv hauv tsev, hluav taws xob thiab lwm yam khoom.
