Detail explanation:
Aluminum foil surface with hydrophilic layer has a strong affinity for water, condensate on the fins spread quickly, not easy to form a "water bridge", so the ventilation effect of air conditioning operation works well. A measure of hydrophilicity is called a hydrophilic angle. Please find the comparison between ordinary aluminum foil and hydrophilic aluminum foil in the following table.
(1)Film with corrosive resistance inorganic resin
(2)Hydrophilic film: organic resin
| SERIAL NO | ITEMS | TESTING METHODS | RESULTS |
| 1 | superficies and appearance | by eyes | golden, blue, black |
| 2 | film thickness | calculated from weight of film | 2-3μm |
| 3 | original hydrophilicity | test hydrophilicity directly | ≥8mm |
| 4 | initial hydrophilicity | dip in vaporing oil 3min (20±15℃) →vertical situation 7min at normal temperature → 210±10℃ dry 2mic → dip in pure water 10min → dry 10min/cycle at normal temperature, 10 circle → test hedrophilicity | ≥6.0mm |
| 5 | salt-spray resistance | JIS-Z-2371 (5%x35℃x72hours continuious slat spray | ≥R.NO9.5 |
| 6 | heat resistance | A:200℃x10mins B:400℃x10mins | A:no changes B:turns light brown |
| 7 | oil resistance | dip in press oil 24hours → wash in flowing water → peel test | no delamenation |
| 8 | adhensive force | A,bending 180° B,peel test C,erichsen value = 5mm | 100% no delamination |
| 9 | odor | by nose after dipping in water, and drying naturally | no odor |
