Title: Formation of polytetrafluoroethylene resin coating film
Inventor: KOBAYASHI SHIGEKI
IPC: B05D3/02
Filed: 1992-06-05
Abstract: PURPOSE:To efficiently obtain an industrially advantageous polytetrafluoroethylene(PTFE) resin coating film having less flaws and high mechanical characteristic by applying the dispersion of a specified PTFE resin, drying and then baking the coat at a specified temp. for a specified temp. CONSTITUTION:The aq. dispersion of a PTFE resin with the diameter of the primary particle controlled to 0.3-0.6mum is applied, dried and then baked at 365-420 deg.C for >=5min. The baking is insufficient at <365 deg.C even if the baking time is increased, the resin is adversely decomposed at >420 deg.C, and the mechanical characteristic is deteriorated. Meanwhile, when the diameter of the primary particle is controlled to <0.3mum, the generation of coating film flaws is not sufficiently suppressed, and the settling velocity of the primary particle in the dispersion is increased beyond the practical range at >0.6mum.

A survey equipment 16 is set between the light generation device 3 and the reflecting mirror 2 having optical axes agreed with each other. A virtual image passing cross hairs 16a inside the survey equipment and returning to the light generator 3 after being reflected at the mirror 9, and a real image returning directly to the light generation device 3 after reflected at the cross hairs 16a are observed by the eye 17 of a measuring person. A shielding part is set in the light generation device 3 so as to prevent an external light from entering the middle of an inspection optical path.  If the real image 18 and virtual image 19 of the cross hairs 16a agree with each other, a collimation line of the survey equipment 16 is horizontal. Unless the images agree with each other, the collimation line is not horizontal. Moreover, errors are observed twice an actual level by the mirror 9.
