摘要:
An o/w water paint having excellent dispersibility and stability is prepared according to a phase conversion process comprising adding ammonia or an amine and water to a solution of an epoxy resin, a hardener resin, and an acrylic resin in an organic solvent or to a molten mixture of these resins to neutralize the acrylic resin. In view of adhesion of a coat to metal and workability, branched alkylamines or heterocyclic amines are suitable as the neutralizing amines. In applying this paint, steam optionally containing fine water droplets is preferably applied to a wet coat prior to drying. Furthermore, a process for the continuous production of an emulsion type water paint comprising a carboxyl group-containing acrylic resin component, an epoxy resin component and a curing agent resin component for the epoxy resin is disclosed.

摘要:
The object of the present invention is to provide an oxygen-absorbing resin composition having a high oxygen absorbability and capable of absorbing oxygen for a long period of time. The present invention provides an oxygen-absorbing resin composition comprising polyolefin resin (A) obtained by polymerizing an olefin having 2 to 8 carbon atoms, resin (B) which is other than resin (A) and which acts as a trigger for the oxidation of resin (A), and transition metal catalyst (C), wherein resin (B) is dispersed in the matrix of resin (A) so that the oxidation reaction of matrix resin (A) is caused and thus oxygen is absorbed when the oxygen-absorbing resin composition is brought into contact with oxygen. This oxygen absorbing resin composition has a high oxygen absorbability and is advantageous in cost because oxygen is absorbed in resin (A).

A wireless communication device or an access point includes: a main unit; an external antenna unit; a throughput check module; and a notification controller, a notice applying circuit and a notice generating circuit. The main unit is for including a communication control circuit. The external antenna unit is for including an antenna and is electrically connected with the main unit via a cable. The throughput check module is for checking throughput of communication with another wireless communication device or a station. The notification controller, the notice applying circuit and the notice generating circuit are for notifying a user of system information based on check result by the throughput check module, by using the external antenna unit. This configuration improves the work efficiency of antenna adjustment at the wireless communication device using the external antenna unit.

In the present invention, a plurality of fixed flats are disposed in juxtaposition to one another, and an opening 5 to 33 mm wide is formed between each pair of adjoining fixed flats, in such a manner that the dust is entrained in the discharge air current produced at the upstream side of the opening and extracted out of the opened fiber mass.
摘要:
A multi-layer structure comprising a functional resin layer obtained by covering a core layer of a base body resin or a second functional resin with a shell layer of a first functional resin, and a base body resin layer containing the functional resin layer therein. The layers of the functional resins are formed at positions where they are allowed to exhibit their functions to a sufficient degree, a plurality of functions can be imparted, and a molten resin mass having the above multi-layer structure can be formed by the compression-forming.
