Nto pretreatment tswj
Ntxuav qhov chaw los ntawmSa2.5 abrasive tawgtshem tawm zeb nplai, roj, thiab oxides. Ib tug huv, uniformly roughened nto ho speeds pib oxidation thiab patina tsim. Tawm hauv zeb nplai los yog cov kab mob yuav ua rau qeeb lossis tsis sib npaug ncua kev loj hlob patina.
Tswj cov voj voog ntub-qhuav
Artificially tsim cov ntub dej tsis tu ncua (txhaj dej) ua raws li kev ziab kom txaus kom simulate qhov zoo tshaj plaws ntawm ntuj raug. Qhov nruab nrab, rov ntub-qhuav cycles yog txoj hauv kev zoo tshaj plaws los ua kom cov patina loj hlob zoo ib yam. Tsis txhob ntub dej mus tas li, uas ua rau xoob xoob es tsis txhob ruaj khov patina.
Environmental condition tswj
Tswj ambient humidity (ze li 60-80%) thiab kub (15-30 degree) kom optimize oxidation kinetics. Xyuas kom qhov cua zoo thiab tshav ntuj raug, uas txhawb kev nrawm, txawm tias txheej txheej. Sheltered, tsaus ntuj, los yog tsis zoo ventilated thaj chaw qeeb patina tsim drasticly.
Accelerated chemical kev kho mob (artificial patination)
Siv ib qho me me, tswj patina accelerator (feem ntau dilute cov kev daws teeb meem uas muaj Cu²⁺, Fe³⁺, lossis phosphates) txhawm rau ua kom sai, zoo li oxidation. Qhov no tuaj yeem ua kom luv patina tsim los ntawm 1-3 xyoos mus rau ob peb lub lis piam. Kev kho mob tsuas yog ua kom nrawm tsim yam tsis tau txo qis kev ruaj ntseg mus ntev.
Exposure orientation thiab tsim optimization
Txhim kho panels vertically nrog cov kua dej zoo kom tsis txhob muaj dej tuav. Kab rov tav, ntxoov ntxoo, los yog qhov chaw nyob ib puag ncig tsim patina qeeb qeeb thiab tsis tshua muaj zog. Tsim kom raug ua kom muaj kev sib raug zoo thiab nrawm dua, zoo ib yam patina.
Tsis txhob hnyav corrosive xov xwm thaum ntxov tsim
Thaum lub sij hawm pib patina-forming theem, tsis txhob raug cov tshuaj ntsev ntau, muaj zog acid gases, los yog hnyav industrial pollution. Cov no ua rau tsis sib xws, xoob xeb thiab ua rau txoj kev loj hlob ntawm ib qho ruaj khov, tuab txheej.
Tswj qhov roughness
Qhov nruab nrab roughness (Ra 40-80 μm) los ntawm blasting txhim kho oxide adhesion thiab ceev kev pab them nqi. Overly du los yog ntxhib heev ob qho tib si txo patina uniformity thiab tsim tus nqi.
