Adhere the first 102mm of a 178mm X 12.7mm (4“ of a 7“ X 0.5“) carbon filter material pre-bonded with transfer tape onto the appropriate resin substrate. A 2.3 kg (5 lbs) roller should be used to obtain uniform pressure when applying the carbon filter ma
7、terial to the resin plaque. 10 specimens are needed (See Figure 1) for testing. Inspect for streaks, blisters, or wrinkles. 2. Cure bonded test specimens for 24 hours at 23oC (73oF) before starting test. Set 5 specimens aside for initial adhesion testing to be performed in step 8 of this procedure.
8、3. Apply drop wise 0.25 ml of SAE 10W30 oil heated to 110oC (230oF) over the bonded filter strips. 4. With the use of a rubber policeman distribute the oil evenly over the bonded area. 5. Place samples horizontally in an oven for 2 hours at 110oC (230oF). 6. Remove specimens from oven and allow samp
9、les to equilibrate at room temperature for one hour. 7. Examine carbon paper and adhesive backing for visual evidence of peeling, loss of adhesion, wrinkling, loss of printing or legibility, or any other effect which would detract from its proper function. 8. Perform peel strength within one hour of
