experiment example 1
[0120] In Experimental Example 1, a cylindrical body made of SUS 304 stainless steel and having an outer diameter of 600 mm, a thickness of 1.2 mm, and a length of 900 mm was prepared as the cylindrical portion 2 . The cylinder is obtained by crimping and welding a plate having a thickness of 1.2 mm. Sand the seams well to eliminate tendons and steps. The cylindrical portion has a sufficiently small thickness relative to the outer diameter. Thus, the cylindrical portion 2 is deformed by its own weight, and cannot maintain the cylindrical shape without being supported. The surface of the cylindrical portion 2 was roughened by blasting the surface of the cylindrical portion 2 with spherical aluminum particles so that the roughness Ra was 0.4 μm.
[0121] A silicon-based release agent (manufactured by Shin-Etsu Chemical Co., Ltd., trade name: SEPA-COAT (registered trademark)) was applied on the surface of the cylindrical portion 2 by spraying. Then, the cylindrical portion 2 w...
