Embodiment Construction
[0029] The present invention will be described in detail below in conjunction with the accompanying drawings and specific embodiments.
[0030] The electropolishing method for cylindrical stainless steel thin-walled bellows of the present invention comprises the following steps:
[0031] Step 1: Degreasing the stainless steel bellows blank
[0032] The composition of degreasing solution is: NaOH 20~50g / L, NaOH 2 CO 3 30~80g / L,Na 3 PO 4 12H 2 O 20~60g / L, Na 2 SiO 3 1~6g / L;
[0033] The preferred value is: NaOH 30g / L, NaOH 2 CO 3 60g / L, Na 3 PO 4 12H 2 O 55g / L, Na 2 SiO 3 5g / L.
[0034] Step 2: pickling the corrugated pipe after degreasing in step 1
[0035] The composition of the pickling solution is: H 2 SO 4 80g / L~100g / L, HNO 3 60g / L~90g / L, HF 40g / L~50g / L, sulfonated coal or urotropine 1g / L~1.5g / L; time 5min~10min;
[0036] The preferred value is: H 2 SO 4 90g / L, HNO 3 80g / L, HF 45g / L, urotropine 1g / L, time 8min.
[0037] Step 3: Fix the corrug...
