Description

Hollow medium density fiberboards

Technical field

The utility model relates to wood-based plate, particularly the Technologies of Medium Density Fiberboard field.

Background technology

At present, at fields such as furniture, construction material, car and boat, extensive use medium density fibre board (MDF).Medium density fibre board (MDF) raw material sources general, timber, skill fork material, sapwood, sawdust, waste and old wood fiber material, bamboo, natural and crops tangerine bar, bagasse, husk etc. can become the material of medium density fibre board (MDF).Compare with natural timber, medium density fibre board (MDF) can be made large-breadth plates by using, saves the precious timber resource, improves the timber comprehensive utilization ratio.Compare with glued board, can save big footpath level log resource, compare with particieboard, the medium density fibre board (MDF) fiber is thinner, even, attractive in appearance, more near natural timber.Medium density fibre board (MDF) is with its unique characteristics, and at home and abroad development in recent years is rapid, and has become the wood-based plate kind of China's maximum production.

At present, medium density fibre board (MDF) is entity sheet material, and it is many to have fibrous material consumption, and the plate body own wt is bigger, the shortcoming that cost is higher.

The utility model content

The purpose of this utility model is, a kind of hollow medium density fiberboards is provided, it is big not only to have the medium density fibre board (MDF) breadth, fiber exquisiteness, attractive in appearance, and dimensional stability is good, raw material sources are extensive, save natural big footpath level timber, be convenient to secondary and decorate performance characteristics such as processing, it is many also to solve the consumption of medium density fibre board (MDF) fibrous material, the plate body own wt is bigger, the shortcoming that cost is higher.

The technical solution of the utility model is: have several hollow holes in the medium density fibre board (MDF) plate core.

Hollow hole in this hollow medium density fiberboards plate core forms in the making sheet process, rather than obtains by boring with solid medium density fiber, neither do that the panel frame idle pattern forms with two solid medium density fibre board (MDF)s.

This hollow medium density fiberboards thickness 6mm～100mm, hollow hole pore size 3mm～80mm hollow hole be 2mm～45mm closely from the plate surface.Hollow hole can be evenly distributed in the plate core, can be inhomogeneous arrangement, also can be row or a multiple row.Pitch of holes can be identical, also can be inequality, and the pitch of holes size is set according to the function needs, and according to user's needs, holding screw as assembling needs local certain position assurance solid, can adjust plate core hollow core hole pitch of holes and obtain.Hollow hole can be the through hole that passes full wafer plate plate core, also can be blind hole.The shape in plate core hollow core hole can be circular hole, slotted eye or approximately circular opening, slotted eye (influence forms because of being stressed), also can be the hole of other shapes such as rectangle, prismatic.

Same hollow hole in the plate core, its aperture can be identical, and also can an end big, an end be little, so that make things convenient for process to implement in case of necessity.

This hollow medium density fiberboards can also be carried out following process and be handled, as paint, mount exterior material, this hollow medium density fiberboards through hole class, also can with the size close, the medium density fibre board (MDF) stopper sealing of hole that color is close, follow-up use processing when being convenient to its application.

China generally is set at 0.45～0.88g/cm with medium density fibre board (MDF) density usually ³, 0.88g/cm, be high density fiberboard, be lower than 0.45g/cm ³, be softboard.Hollow medium density fiberboards of the present utility model, because the existence of hollow hole, the proportion of its entire plate (or bulk density) will reduce, and generally can be adjusted into 0.25～0.88g/cm ³, plate body density (not containing hollow parts) can be greater than 0.88g/cm ³, promptly comprise high density fiberboard.This hollow medium density fiberboards comprises wood fibre, bamboo fibre, tangerine rod fibers, and all kinds of reinforcing material, the medium density fibre board (MDF) that packing material etc. are made.

The utility model has the advantages that: because this hollow medium density fiberboards plate heart has some hollow holes, and these hollow holes form in the making sheet process, rather than obtain by boring with solid medium density fibre board (MDF), therefore, compare with the common solid medium density fibre board (MDF) that same thickness, length, width and same process are made, save fibrous material, alleviated the plate body own wt, reduced the cost of every plate.Hollow medium density fiberboards can be saved a large amount of fibrous materials according to user's needs and serviceability requirement, and hollow hole duty fiberboard volume ratio in the heart generally can reach 10～80%.Because the existence of these hollow holes is compared with the entity MDF in the hollow medium density fiberboards plate core, heat insulation, soundproof effect is improved.

Because hollow MDF particular structure characteristics make it have higher structural strength and favorable shock resistance.It is big that hollow medium density fiberboards has also kept the medium density fibre board (MDF) breadth, the fiber exquisiteness, and material is more even, appearance looks elegant, dimensional stability is good, and raw material sources are wide, and is cheap, and saw cuts a series of superior function characteristics such as convenient.Therefore, these sheet material super quality and competitive price are good products that wood-based plate updates, and have great application value in fields such as furniture, timber, building, car and boat.
