摘要:
A polymer article containing zeolite particles on which metal ion having a bactericidal property, e.g. Ag, Cu or Zn, is provided by an ion exchange reaction shows an excellent bactericidal effect and durability of the effect, but no deterioration of physical properties of the polymer.The polymer article is produced by admixing zeolite particles previously provided with the metal ion with a polymer or by moulding a zeolite-containing polymer into an article and then treating the article with a metal ion solution.
摘要:
Zeolite particles retaining at least one metal ion having bacteriostatic properties on their ion-exchangeable sites in an amount up to 41% of the zeolite's ion exchange capacity are described.

Zeolite particles retaining silver ions having bacteriostatic properties on their ion-exchangeable sites in an amount up to 41% of the zeolite's exchange capacity are described.
摘要:
Specific zeolite particles retaining therein a metal ion having a bactericidal activity are packed and retained in a mixed fiber assembly composed of low-melting thermoplastic synthetic fibers and ordinary fibers. The zeolite particles are retained by welding of the low-temperature thermoplastic synthetic fibers but in a state of allowing the contact thereof with an external fluid. The particle-packed fiber article has an excellent and durable antibacterial activity and can be used in various fields.
摘要:
An oil and heat resistant pressure-sensitive adhesive sheet includes a substrate containing a fluororesin, and a pressure-sensitive adhesive layer laminated on at least one surface of the substrate. The one surface of the substrate is subjected to a surface roughening treatment and/or a primer treatment, and the pressure-sensitive adhesive layer is formed from an aqueous dispersion type oil-resistant pressure-sensitive adhesive composition containing an aqueous dispersion polymer and inorganic particles.

A leather-like material having a soft feed and a high water vapor permeability comprises a substrate of a fiber aggregate and a microporous grain layer mainly comprising a polyurethane elastomer and having an average thickness between 20 .mu.m and 300 .mu.m, preferably between 20 .mu.m and 200 .mu.m, more preferably 20 .mu.m and 100 .mu.m. The grain layer has an inner layer portion permeating partly into interstices of the fiber aggregate and bonding thereto, a topside having been coagulated to set up with a flat and smooth, or animal skin-like, grain appearance and micropores having an average pore diameter gradient of from at least 4 .mu.m in the inner layer portion to at most 3 .mu.m in the surface layer portion. The leather-like material is characterized by a water vapor permeability of from 1 to 30 mg/cm.sup.2.hr and a Gurley stiffness ratio of article to substrate of at most 1.5. The leather-like material of the invention is manufactured by a process comprising the steps in sequence of: coating a release belt with a water-miscible solvent solution of a polyurethane elastomer; superimposing a water-moisturized substrate on the coated solution; heating the topside surface of the substrate to coagulate said polyurethane elastomer by the action of saturated water vapor forming within the substrate; and then releasing the resultant leather-like material from the release belt, followed by washing with water and drying.

A cage consists of a pressed annular metal cage member (6) and one or two molded plastic roller retaining member(s) (10). Each roller retaining member (10) includes a cylindrical part having pockets for receiving a bearing roller (3) and an annular flange or flanges (8) formed either on only one axial end or on both axial ends of the cylindrical part. Each roller retaining member comprises an annular ring portion (11) having an annular side face engaged by an annular outside face of the flange (8) of the case member, (6) and an annular fitting face 17 to be lightly engaged with or spaced apart by a slight gap from either a radially inner face or outer face of the flange. Teeth (12) transversely project between the rollers (3) for preventing slipping out of any bearing roller. A plurality of lips for coupling and locking the roller retaining member to the flange of cage member (6) are, also, formed on the ring portion.

An assembled battery device (1) of the present invention includes: a plurality of single cells (11) electrically connected to each other and arranged in a row; and a thermal emission tape disposed between a single cell (A) and a single cell (B) that are adjacent to each other among the plurality of single cells (11). The plurality of single cells (11) each include battery elements and a metallic container (12) housing the battery elements. The thermal emission tape is attached to at least a portion of a surface of an outer wall of the container of the single cell (A), and/or to at least a portion of a surface of an outer wall of the container of the single cell (B), the surface of the outer wall of the container of the single cell (A) facing the single cell (B), the surface of the outer wall of the container of the single cell (B) facing the single cell (A). The thermal emission tape has a total emissivity of 0.7 or more at a wavelength of 2 μm to 14 μm.

A thermally conductive film (10) includes a matrix (12) made of a resin and flaky filler particles (14) dispersed in the matrix (12). The flaky filler particles (14) each has a flaky filler body (16) made of boron nitride and a γ-ferrite coating (18) on the filler body (16), and are oriented in a through-thickness direction of the thermally conductive film (10). The resin is, for example, polyimide.
