閉路循環(huán)除銹劑的應(yīng)用
APPLICATION OF CLOSED-CIRCULATING RUST REMOVER
-
摘要: 用能再生的無(wú)機(jī)鹽除銹劑代替酸洗除銹,實(shí)現(xiàn)不排放"三廢"的閉路循環(huán),并采用連續(xù)再生方法,保證穩(wěn)定的除銹速度,能滿足大規(guī)模連續(xù)焊管生產(chǎn)的需要。Abstract: With the recoverable inorganic saline rust remover as a replacement of rust-pickling, a closed-circulation operation without exhausting the so-called "Three Major Polluting Wastes" can be obtained, and consistent descaling rate ensured due to adoption of the continuously recovering process so as to meet massive continuous production of welded pipes.
