(for the preparation method of examination material)
First, make fin material by following method.
By existing known manufacture method, manufacture the aluminium sheet (thickness of slab 0.10mm) of A1200 (JIS H4000) formation that is by fine aluminium.Then, aluminium sheet be impregnated in to alkaline reagent (Japanese coating society manufactures " SURFCLEANER (registration mark) 360 "), carry out thus the degreasing in 5 seconds.In addition, impregnated in phosphoric acid chromate solution and (convert and count 30mg/m with Cr at the epithelium of surface of aluminum plate formation chromium phosphate hydrochlorate
2).And, with metering bar coater to this aluminium sheet of having implemented the processing of chromium phosphate hydrochlorate be coated on the corrosion resistance coating shown in table 1 and baking after, with metering bar coater be coated on the hydrophilic coating shown in table 2 and baking.Then,, on the surface of hydrophily skin membrane, be coated on the lubricious coatings shown in table 3 with metering bar coater and also toast.

[table 3]
(note) PEG:PEG20000 (Sanyo changes into industry system) (polyethylene glycol)
(note) CMC alkali metal salt: CELOGEN (registration mark) PR (the first industrial pharmacy system) (sodium carboxymethylcellulose)
The fin material (sample 1～42) that uses made, by following method evaluation hydrophily, coefficient of friction, punch process, the results are shown in table 4, table 5.
[table 4]
[table 5]
(hydrophily evaluation: hydrophily cyclic test)
The fin material of made (sample 1～42) is flooded after 8 hours in flow is the circulating water of 0.1L/ minute, 80 DEG C dry 16 hours, above operation, as 1 circulation, has been carried out 25 circulations.Implement after this hydrophily cyclic test, the fin material (sample 1～42) of making is back to room temperature, drip the pure water of approximately 0.5 μ L on surface, use contact angle determination device (consonance Surface Science society manufactures: CA-05 type) to measure contact angle.Flow water is that the situation of running water and the situation of pure water (ion exchange water) are measured respectively.Metewand is as follows.Contact angle is good (zero) lower than 70 °, contact angle be 70 ° above and lower than 80 ° be roughly good (△), it is bad (×) above that contact angle is 80 °.
(processability evaluates 1: coefficient of friction)
The fin material (sample 1～42) of making is used to Bowden (Bowden) formula viscosity sliding test machine, measure coefficient of friction with the condition without oiling, load 0.2kgf, translational speed 4mm/ second.About metewand, coefficient of friction is good especially (◎) lower than 0.15, more than 0.15 and lower than 0.2 being good (zero), more than 0.2 and lower than 0.35 being roughly well (△), more than 0.35 be bad (×).
(processability evaluates 2: punch process)
Fin material (sample 1～42) punch process of enforcement based on calendaring molding or the punch process based on stretch forming of making are made to fin, evaluate by the formability of utilizing naked eyes confirmation to implement the collar portion of the fin after continuous 10,000 times.
The situation that the inner face of the collar portion of the fin after shaping does not confirm the cob webbing problems such as ablation is completely good (zero), the situation that confirms the cob webbing problems such as slight ablation at the inner face of collar portion is roughly good (△), and the situation that confirms the cob webbing problems such as ablation at the whole face of the inner face of collar portion is bad (×).It should be noted that, at least one of calendaring molding and stretch forming is evaluated as to roughly good (△) above qualified as punch process.
As shown in table 4, for sample 1～33 (embodiment), all possess the lubricity epithelium that contains crosslinking agent with the solid constituent ratio of prescribed limit, therefore hydrophily and punch process are good.
As shown in table 5, about sample 34,35,37,38 (comparative example), in lubricity skin membrane all not containing the solid constituent ratio of crosslinking agent or the crosslinking agent that comprises all lower than 0.2 quality %, therefore hydrophily is bad.In addition, about sample 36,39, the solid constituent ratio of the crosslinking agent comprising in lubricity skin membrane all exceedes 70 quality %, and therefore punch process is bad.Further, about sample 40～42, do not possess lubricity skin membrane, therefore hydrophily and punch process are bad.
