    摘要: 【課題】ホルムアルデヒドとアセトアルデヒドの双方を効果的に捕捉分解することのできるアルデヒドを捕捉分解する繊維板を提供する。
    【解決手段】アルデヒドを捕捉分解する繊維板20は、植物繊維を少なくとも30質量%以上含む木質繊維板1と、繊維板1の両側面の側面内部に浸透固化したカルボジヒドラジド2を少なくとも含むアルデヒド捕捉剤と、からなる繊維板である。 アルデヒド捕捉剤は木質繊維板1の一側面の内部にのみ浸透固化されていてもよい。 また、木質繊維板以外にも樹脂繊維と植物繊維の混合板を使用することができる。 カルボジヒドラジドは、界面活性剤とともに水溶液の状態で木質繊維板等にスプレー塗布等される。

    摘要: PROBLEM TO BE SOLVED: To provide a production method for a natural rubber having lowered viscosity or lowered stable-viscosity, which has excellent dynamic properties, low viscosity or low stable-viscosity, and excellent processability; to provide a natural rubber obtained thereby; and to provide a rubber composition containing the natural rubber.
    SOLUTION: The production method for the natural rubber having lowered viscosity or lowered stable-viscosity, is carried out by the followings. A natural rubber latex is decreased in the metal content by the treatment of adding a water-soluble ammonium salt thereto, and after optionally adding a viscosity stabilizer to the treated natural rubber latex, the latex is subjected to pulse drying by spraying it to a pulse wave atmosphere, yielding a solid rubber. The natural rubber obtained thereby and the rubber composition containing the natural rubber are also provided.

    摘要: PROBLEM TO BE SOLVED: To provide a fiberboard for capturing and decomposing aldehydes capable of effectively capturing and decomposing both of formaldehyde and acetoaldehyde. SOLUTION: The fiberboard 20 for capturing and decomposing aldehydes comprises a wooden fiberboard 1 containing at least 30 mass% of vegetable fibers, and an aldehyde capturing agent at least containing a carbodihydrazide 2 infiltrating to be solidified inside both the side surfaces of the fiberboard 1. The aldehyde capturing agent may be infiltrated and solidified only inside a side surface of the wooden fiberboard 1. Also, a mixed board of resin fibers and vegetable fibers other than the wooden fiberboard can be used. The carbodihydrazide is applied by spraying or the like for coating the wooden fiberboard or the like together with a surfactant in the state of a water solution. COPYRIGHT: (C)2008,JPO&INPIT
