Cov FAQ
Q1: Puas tsim nyog rau cov dej siv tau siv tau?
A: Txwv! Arsenic leaching kev pheej hmoo. Siv tsuas yog hauv kev muaj cov dej txias txias.
Q2: Yuav ua li cas los daws vuam porosity?
A: tshwm sim los ntawm AS / ZN Volatilization. Siv ntau dua los yog sib npaug rau 99.99% Argon, Preheat 150-200 Degree {{}}} × 1h.
Q3: Yuav ua li cas tiv thaiv kev tawg kub?
A: Tswj me me oxidizing huab cua (O₂: 0.5-1.5%), txwv lub sijhawm ntsuas kub tsawg dua los yog sib npaug rau 2h.
Q4: Yuav ua li cas los xaiv vs. c44300 tin tooj dag?
A: C68700 muaj cov dej hiav txwv zoo tshaj plaws & 15% txo tus nqi; C44300 yog arsenic - dawb rau cov ntawv thov neeg pej xeem.
