CN2376375Y - Thick core bamboo plywood - Google Patents

Abstract

The utility model relates to a thick core bamboo plywood, which belongs to the field of processing a single board or a plywood. The utility model is characterized in that a rough bamboo part is divided into arc bamboo plates to be shaped and processed with segment removal into the arc bamboo plates with original thickness and cutting degree. The bamboo plates are erected by sides by a nylon wire to be cascaded into a core layer. After the surfaces are flatly surfaced, the bamboo plates are glued into integration with a surface layer by hot compression. The utility model has the characteristics of high bamboo utilizing rate and high anti-bending strength. The manufacture cost of the product is low, the bamboo utilizing rate is more than 80%, the used adhesive quantity is reduced by 40% and the bamboo plates keep the original structure form. By being tested, the longitudinal anti-bending strength of the product is more than 150 Mpa. The utility model can be widely used for the industries of containers, construction, etc.

Description

A kind of thick core bamboo plywood

A kind of thick core bamboo plywood belongs to processing veneer or glued board.

At present the bamboo plywood of producing mainly contains products such as bamboo plywood, bamboo plywood, bamboo mat plywood and bamboo wood composite veneer, all is bamboo processing to be become to glue together behind the tangential plane bamboo chip form.Because the shape of bamboo wood is the cylindrical of sky in the thin-walled, when therefore the arc bamboo chip being processed into the tangential bamboo chip of uniform thickness of Bao Erping, the utilization rate of bamboo wood is not high.CN2161443Y discloses a kind of container bamboo plywood, dry behind the inner skin of a bamboo stem impregnation by multilayer certain thickness and width, press the dress of direction layering in length and breadth mould, make product with the hot press hot-press solidifying then, though general bamboo plywood transverse strength height, but complex manufacturing, and the utilization rate of bamboo wood is still on the low side.

The purpose of this utility model is to provide a kind of utilization rate of bamboo height, the thick core bamboo plywood that production cost is low.

Solution of the present utility model is, mao bamboon is split into the arc bamboo chip, goes then to save and finalize the design to be processed into the arc bamboo chip that keeps original thickness of bamboo wall and degree of cutting, and with the synthetic sandwich layer of the edge-on string of nylon yarn, the surface is integral with the surface layer hot-press gluing after planing.

The utlity model has the high and big characteristics of bending strength of utilization rate of bamboo.The production cost is low, and utilization rate of bamboo reaches more than 80%, and the adhesive consumption reduces 40%; And bamboo chip has kept original structural form.After tested, vertical bending strength of product reaches more than the 150Mpa, can be widely used in industries such as container and building and use.

Accompanying drawing is a cross-sectional view of the present utility model.Central layer 2 is closed by arc bamboo chip string and forms, and is bonded with surface layer 1 on its upper and lower two faces.

Embodiment: 500 * 65 * 3000mm concrete blinding.The arc bamboo chip is of a size of 60 * 3000mm, and with the central layer of the synthetic wide 500mm of the edge-on string of nylon yarn, the surface forms with the hot pressing of bamboo mat surface layer behind the impregnated phenolic resin through planing.

Claims (1)

1, a kind of thick core bamboo plywood of being made up of arc bamboo chip, nylon yarn, surface layer and bamboo glue is characterized in that: arc bamboo chip side elevation has the surface layer with the bamboo glue glued adhesion with the synthetic sandwich layer of nylon yarn string on its upper and lower two faces.
