摘要:
A biodegradable resin bottle having a container wall (1) including a biodegradable resin and having a vacuum-evaporated film (3) formed on the inner surface of the container wall (1) by a plasma CVD method. The vacuum-evaporated film (3) includes a first hydrocarbon vacuum-evaporated layer (3a) positioned on the inner surface of the container wall and a second hydrocarbon vacuum-evaporated layer (3b) formed on the above hydrocarbon vacuum-evaporated layer (3a). The first hydrocarbon vacuum-evaporated layer (3a) has polar groups introduced therein. The second hydrocarbon vacuum-evaporated layer (3b) exhibits hydrocarbon peaks stemming from CH, CH2 and CH3 in a region of wave numbers of 3200 to 2600 cm−1 as measured by FT-IR, has a CH2 ratio of not larger than 35% and a CH3 ratio of not smaller than 40% per the sum of CH, CH2 and CH3 calculated from the hydrocarbon peaks, and has no polar group introduced therein.

To achieve a sufficient drainage of condensed water (dew water) adhering to a surface to suppress an adverse effect on an airflow resistance and a heat exchange efficiency, even in a case where heat exchange tubes are arranged horizontally, provided is a drain structure for a corrugated fin-type heat exchanger (1), the corrugated fin-type heat exchanger (1) being constituted by arranging a plurality of flat heat exchange tubes (3) parallel to one another in a horizontal direction between a pair of opposing header pipes (2a, 2b), and joining corrugated fins (4) between the plurality of flat heat exchange tubes (3), the drain structure including a plurality of water flow passages (10) for inducing water retained between the corrugated fins (4) adjacent to an upper side and a lower side of each of the plurality of flat heat exchange tubes (3), the plurality of water flow passages (10) being formed on an outer end surface of the each of the plurality of flat heat exchange tubes (3) in a width direction thereof at a pitch along a longitudinal direction of the each of the plurality of flat heat exchange tubes (3).
摘要:
A plastic formed article comprising a plastic substrate and a vapor deposited film formed on the surface of the plastic substrate by a plasma CVD method, wherein the vapor deposited film includes an organometal vapor deposited layer having an element ratio C/Si of 2.5 to 13 and an element ratio O/M of not larger than 0.5, and a hydrocarbon vapor deposited layer; and the hydrocarbon vapor deposited layer has a thickness in a range of 40 to 180 nm, exhibits peaks stemming from CH, CH2 and CH3 over a region of wave numbers of 3200 to 2600 cm−1 as measured by FT-IR, and has a CH2 ratio of not larger than 35% and a CH3 ratio of not less than 40%. A film is deposited on a plastic formed article without deteriorated by oxidation, without thermally deformed or without thermally deteriorated not only when PET or polyolefin is used but also when polylactic acid is used as the plastic substrate.

摘要:
This invention relates to a process for priming an aluminum material by applying a primer containing the nitrate or related compound of a metal selected from aluminum, zirconium, cerium, chromium, and iron to the surface of the aluminum material so that the amount of adhering metal becomes 1.0 mM/m2 or more and baking the primer, and also relates to a primer for an aluminum material containing water-soluble acrylic acid-based polymers in the range of 3.5 to 22.5 g/l as solids concentration, the nitrate or related compound of a metal selected from aluminum, zirconium, cerium, and iron in the range of 30 to 500 g/l, a hydrofluoric acid-based compound in the range of 1.0 to 5.0 g/l as elemental fluorine, and an organic reducing agent in the range of 5 to 30 g/l. This invention makes it possible to apply a primer to the surface of an aluminum material with excellent corrosion resistance.
摘要:
To enable the mass injection of a sample in a gas chromatography and prevent occurrence of residue or decomposition of a desired constituent during analysis. The invention calls for providing the injection port with a liner, connecting the column and the liner to a press-fit, evaporating the solvent introduced into the liner, and discharging the evaporated solvent from a discharge port formed at the upper part of the liner.
