Faa'iidooyinka iyo qasaarooyinka chromium Plating Trivalent

Marka hore, waa maxay Trivalent?

Waa aqurxin qurxin leh, kaas oo bixin kara xoqan iyo iska caabin daxalka ee xulashooyinka midabka kala duwan.chrome Trivalentwaxaa loo arkaa beddelka deegaanka-saaxiibtinimo ee chromium hexavalent.

Marka xigta, aan si qoto dheer u eegno habkan si aan u fahamno faa'iidooyinka iyo khasaaraha.

Faa'iidooyinka

Faa'iidooyinka ku jirahababka chromium trivalentIn ka badan nidaamka chromium ee hexavalent ayaa ah walaac deegaan oo yar sababtoo ah sunta hoose ee chromium trivalent, wax soo saarka sare, iyo kharashyada hawlgalka oo hooseeya.

Geedi socodka chromium ee trivalent, chromium hexavalent waa wasakh qubeyska dahaadhan.Sidaa darteed, qubayska kuma jiraan wax la qadarin karo oo chromium hexavalent ah.Isku darka isku-darka chromium ee xalalka chromium trivalent waa ku dhawaad ​​shan-meelood meel marka loo eego xalalka chromium ee hexavalent.

Natiijadu waxay tahay kimisteriga trivalent chromium electrolyte, miistu ma dhacdo inta lagu jiro dajinta si la mid ah inta lagu jiro dajinta chromium hexavalent.Isticmaalka chromium trivalent sidoo kale wuxuu yareeyaa dhibaatooyinka qashin-qubka iyo kharashyada.

Khasaaraha:

Khasaaraha nidaamka chromium-ka trivalent waa in geeddi-socodku uu aad uga xasaasisan yahay wasakhda marka loo eego habka chromium-ka hexavalent, iyo geeddi-socodka chromium-ka trivalent-ku ma dami karo dhumucda saxanka buuxa ee geeddi-socodka chromium-ka hexavalent uu awoodo.Sababtoo ah waxay xasaasi u tahay faddaraynta, habka chromium-ka trivalent wuxuu u baahan yahay biyo raacid dhamaystiran iyo kontorool shaybaar oo adag marka loo eego habka chromium-ka hexavalent.Qubayska chromium trivalent waxay saxan karaan dhumucdooda u dhaxaysa 0.13 ilaa 25 µm.Looma isticmaali karo badi codsiyada dheesha chromium adag.

Qubayska chromium electroplating trivalent ayaa la sameeyay ugu horrayn si loogu beddelo qurxinta hexavalent ee chromium baths.Horumarinta qubeyska trivalent ayaa la caddeeyey inay adag tahay sababtoo ah chromium trivalent wuxuu ku milmaa biyaha si uu u sameeyo ion adag oo adag oo aan si sahal ah u sii deyn chromium.Waqtigan xaadirka ah, waxaa jira laba nooc oo ah hababka chromium ee trivalent ee suuqa: hal unug iyo laba-unug.Farqiga ugu weyn ee labada hab-socodka ayaa ah in xalka habka laba-unuggu uu ka kooban yahay chlorides-ka ugu yar-ilaa-la'aan, halka habka hal-unuggu uu ka kooban yahay isku-ururin sare oo koloride ah.

Intaa waxaa dheer, habka laba-unuggu wuxuu isticmaalaa anodes-ka rasaasta ee la geliyo sanduuqyada anode ee ay ku jiraan xal sulfuric acid ah oo la milo ah oo lagu daboolay xuub daadi kara, halka habka hal-unuggu uu isticmaalo kaarboon ama graphite anodes oo la dhigo xiriir toos ah xal daadin.Faahfaahinta hababkan lama heli karo sababtoo ah qubaysyada chromium-ka ee trivalent ee hadda suuqa yaal waa kuwo iska leh.

Waa kuwan faa'iidooyinka ugu waaweyn ee Trivalent chrome:

qiiqa sunta ah ee deegaanka u saaxiibka ah ayaa ka yar marka loo eego daasadda hexavalent

Qashinka qashinka oo yaraada

Kharashka daaweynta biyaha wasakhda oo hooseeya

Sharciyada imtixaanada oo yaraada iyo kharashaadka la xidhiidha

Khasaaruhu waa sida soo socota:

Wax yar oo ka sarreeya kiimikooyinka & dayactirka iyada oo ka soo horjeedda dhejinta hexavalent.

· Doorashada anode-ka oo ku adkaata

· Halabuurka xalalka adag

Dhibaato xagga dhumucda dahaarka ayaa korodhay
