Qhov cuam tshuam ib puag ncig ntawm Q460NH xeb khoom:
Tus xeb (patina) tsim rau Q460NH cov huab cua hlau yogtsis suav hais tias muaj teeb meem ib puag ncignyob rau hauv ib txwm muaj mob. Ntawm no yog vim li cas:
Ntuj muaj pes tsawg leeg:
Lub patina muaj feem ntau ntawmLub Nruab Nrab Hlau Oxides(xws li, hematite, gogeite) thiaballoying keeb oxides(Cu, CR, P), uas tsis muaj tshuaj lom thiab insoluble hauv dej.
Tsis zoo li cov pa hlau xeb, Q460NH's patina adheres nruj nreem, txo qis kev tso tawm.
Tsawg LAWM:
Kev tshawb fawb (piv txwv li,ISO 15156) Qhia tias Leaching ntawm cov hlau hnyav (piv txwv li, chromium, tooj liab) los ntawm huab cua hlau xeb yogtsis pom zoonyob rau hauv ph-nruab nrab dej nag.
Acid los nag (Ph<5) may slightly increase metal ion release, but levels typically remain below EPA / uas yog leej twgrau av / dej paug.
Kev coj tus cwj pwm ntev:
Tshaj xyoo lawm, lub patina ruaj khov ntxiv, txo kev sib cuam tshuam ib puag ncig.
HauvCov Ecosystem(xws li, chaw ntub dej), ceev faj zoo liKev Tswj Xyuas Kev Kho MobYuav qhia thaum lub sij hawm pib xeb (thawj 2-3 xyoos).
Thaum xav tau kev ceev faj:
Saline / Industrial Cheeb Tsam: Chlorides / sulfates tuaj yeem ua kom muaj kev sib cav hlau; Kev ntsuam xyuas kev khiav tawm ua ntu zus.
Kev Siv Hluav Taws Xob / Dej Vuam: Siv cov kev txwv (piv txwv li, geotextiles) los cais cov av sib chwv yog cov tswj hwm hauv ib lub zos kom nws.
Kev ceev kev cai: Q460NH ntsibRoHS thiab mus txogCov qauv rau cov khoom tsis muaj kev phom sij. Rau cov phiaj xwm nrog cov ecological ua rau cov ecological, kev kuaj sim (piv txwv li,Taub hau tcl) tuaj yeem lees paub hauv zos sib xyaw ua ke.
