1. Cov txheej txheej chromium muaj cov tshuaj organic zoo siv tau. Nws tsis tsim cov txiaj ntsig hauv alkali, sulfate, sodium cyanide thiab cov kua qaub citric loj, tab sis tuaj yeem yaj halogen acid (xws li sulfuric acid) thiab kub hydrochloric acid;
2. Cov hlau tsis muaj txheej txheej ntawm chrome-plated pas nrig muaj cov yam ntxwv zoo, thiab nws tau siv los ua kev tiv thaiv kev nyab xeeb-kev kos duab zoo nkauj txheej thiab cov txiaj ntsig txheej ntawm cov yeeb nkab. Nws ib txwm muaj feem cuam tshuam hauv kev tsim khoom lag luam ntawm cov txheej txheem electroplating. Nrog rau kev txhim kho kev txhim kho ntawm kev tshawb fawb thiab thev naus laus zis thiab txhua tus neeg tau maj mam thiab qib siab ntawm kev tiv thaiv ntawm cov xwm txheej ib puag ncig, kev txhim kho yooj yim ntawm cov hlau tsis huv thaum ub tau ua rau microcracks thiab microporous chromium, dub chromium, xoob qhov chromium, thiab qis dua cov hlau tsis huv . , Ua raws cov thev naus laus zis tshiab thiab txheej txheem tshiab xws li nyuaj nyuaj chromium plating, trivalent chromium stainless hlau, tsis tshua muaj lub ntiaj teb stainless hlau, thiab lwm yam, txhawm rau txuas ntxiv nthuav dav daim ntawv thov txheej txheej txheej hlau tsis huv.
3. Cov hlau tsis muaj txheej muaj lub zog siab heev. Raws li qhov muaj pes tsawg leeg ntawm cov txheej txheem plating thiab cov lus qhia tshwj xeeb ntawm kev siv tshuab, nws lub zog tuaj yeem hloov pauv ntau yam ntawm 400-120 chrome-plated pas nrig hauv 0HV. Cov hlau tsis muaj txheej muaj qhov kub ua haujlwm zoo. Thaum ua kom sov qis dua 500 ° C, tsis muaj qhov hloov pauv tseem ceeb hauv qhov ci thiab lub zog. Cov xim yuav oxidized ua ntej thaum qhov kub siab tshaj 500 ° C, thiab lub zog yuav raug txo thawj zaug thaum qhov kub siab tshaj 700 ° C. Kev tsis sib haum xeeb ntawm txheej txheej hlau tsis huv yog me me, thiab nws yog qhov tsis sib haum qhuav heev, uas yog qhov tsawg kawg ntawm txhua yam khoom siv hlau. Yog li ntawd, txheej txheej hlau tsis xeb muaj qhov ua haujlwm zoo.
