Полезная модель относится к области виброакустики, а именно к одному из средств вибропоглощения - жесткому покрытию, и может использоваться для снижения уровней вибрации корпусных конструкций судов и других транспортных средств и вызванного ей вторичного шума.Задачей полезной модели является расширение ее функциональных возможностей за счет снижения, без потери эффективности в течение всего срока эксплуатации, уровней вибрации корпусов судов или других конструкций, имеющих постоянный контакт с морской водой или работающих в условиях повышенной влажности, путем применения вибропоглощающего материала, обладающего повышенной стойкостью к воздействию морской воды.Задача решается следующим образом. Вибропоглощающая пластина выполнена в виде монолитного листа постоянной толщины. В качестве вибропоглощающего материала используется полиуретановая композиции. Вибропоглощающая пластина может устанавливаться в межбортном пространстве на внутреннюю поверхность корпуса.Предлагаемая вибропоглощающая пластина, для изготовления которой используется обладающая повышенной стойкостью к воздействию морской воды полиуретановая композиция, дает возможность демпфирования таких конструкций, как корпус судна со стороны межбортного пространства (или трюма).

A shrinkable-stretchable polymeric laminated structure is made up of a shrink-stretch film on the outside and a nonwoven on the inside, with or without an adhesive. Preferably the film, nonwoven and adhesive are made from the same polymer family, including copolymers, which renders the laminate 100% recyclable. The film, nonwoven, and adhesive are modified to provide different responses to heat in addition to controlled water vapor permeability. The structure allows for water vapor permeability in one direction (inside-to-outside) and not in the opposite direction to allow wrapped article to dry or to keep wrapped articles dry and prevent corrosion related damage.

By forming the first bonding layer of an adhesive layer, a necessary strength can be ensured, and also the optical properties can be enhanced by absorbing the irregularities of the polarizing layer formed of a synthetic resin so as to prevent the contamination with air bubbles. Since the time of exposure of the polarizing layer to heat generated by a plasma can be decreased, the polarizing layer is not deteriorated.

Renewable Polyester Film having a Low Modulus and High Tensile Elongation

Номер: US20130209770A1

Принадлежит: Kimberly Clark Worldwide Inc

A film that is formed from a thermoplastic composition is provided. The thermoplastic composition contains a rigid renewable polyester and a polymeric toughening additive. The toughening additive can be dispersed as discrete physical domains within a continuous matrix of the renewable polyester. An increase in deformation force and elongational strain causes debonding to occur in the renewable polyester matrix at those areas located adjacent to the discrete domains. This can result in the formation of a plurality of voids adjacent to the discrete domains that can help to dissipate energy under load and increase tensile elongation. To even further increase the ability of the film to dissipate energy in this manner, the present inventors have discovered that an interphase modifier may be employed that reduces the degree of friction between the toughening additive and renewable polyester and thus reduces the stiffness (tensile modulus) of the film.
