Abstract

Provided is a method for producing a bamboo particle board by using bamboo shavings. The method for producing the bamboo particle board by using the bamboo shavings comprises the following steps of (1) feeding, (2) drying, (3) sorting, (4) glue mixing, (5) mat formation, (6) prepressing, (7) hot pressing and (8) edge sawing, wherein according to the step of glue mixing, modified urea resin glue which is low in molar ratio is adopted, sizing is carried out through the stirring type airflow glue spray method, the amount of the modified urea resin glue which is used is 110kg/m<3>, the pressure of hot pressing is 2.0MPa, the temperature of hot pressing is 170DEG C, and the time of hot pressing is 20s/mm. According to the method for producing the bamboo particle board by using the bamboo shavings, due to the fact that the characteristic that a green bamboo material is good in toughness and high in hardness is adopted, the defect that an ordinary particle board is prone to deformation and low in static bending intensity is overcome, the board surface of a product produced through the method for producing the bamboo particle board by using the bamboo shavings is fine, smooth and high in density, the internal structure of the product is even and cannot easily deform, the product has the advantages of being waterproof, dampproof, environmentally-friendly, firm and durable, meanwhile, bamboo waste is made full use of, loss and waste of forest resources are reduced, and the quality of the product can reach the standard of first-grade products of A-class particle boards of China.

Description

The method of utilizing the bamboo bits to produce the bamboo shaving plate
Technical field
The present invention relates to a kind of method of producing the bamboo shaving plate, relate in particular to a kind of method of utilizing the bamboo bits to produce the bamboo shaving plate, belong to bamboo wood processing technique field.
Background technology
The bamboo shaving plate that traditional handicraft is produced at present, that to take the waste material bamboo bits of bamboo product processing enterprise be primary raw material, utilize Lauxite, the sheet material formed under the condition of heating pressurization, its shortcoming is: the bamboo shaving intralamellar part is prone to absciss layer, the plate face is hard coarse, and density and mechanical strength are inhomogeneous, affect product quality.
Consider the like waste to be worth doing with offal and the bamboo of bamboo product enterprise at present, it is more difficult that particularly the discarded object of green bamboo is produced the bamboo shaving plate, and the offal of bamboo product enterprise and bamboo bits contain than the peracidity thing, sugar part and other compound, the one, the green bamboo content of cellulose is higher than 70%, higher than other mao bamboon; The 2nd, insoluble lignin content is 23.71%, higher than other mao bamboon; The 3rd, content of ashes is that 2.33%. is higher than other mao bamboon; The 4th, benzyl carbinol extract and mass fraction are 1%NaOH, lower than other mao bamboon, thereby are difficult to be used effectively always.
Summary of the invention
The objective of the invention is in order to overcome deficiency of the prior art, thereby a kind of method of utilizing the bamboo bits to produce the bamboo shaving plate is provided.
For achieving the above object, the present invention adopts following technical scheme:
The method of utilizing the bamboo bits to produce the bamboo shaving plate, it comprises the following steps:
Blanking---is dried---sorting---glue mixing------precompressed---hot pressing---the saw limit of mating formation; Wherein: glue mixing is to adopt a kind of low mol ratio modified urea-formaldehyde resin glue, adopts the applying glue of stirring-type air-flow glue spraying method.
The applying glue of described stirring-type air-flow glue spraying method, glue consumption 110kg ∕ cubic meter.
Described hot pressing pressure 2.0MPa, 170 ℃ of hot pressing temperatures, hot pressing time 20s ∕ mm.
Adopt the beneficial effect of technique scheme to be:
The present invention utilizes green bamboo bamboo wood good toughness, characteristics that hardness is high, overcome ordinary particle board yielding, the shortcomings such as MOR is low, the production board face that utilizes the present invention to produce is moist, density is high, internal structure is evenly not yielding, and there is waterproof and dampproof, environmental protection, robust advantage, take full advantage of the bamboo discarded object simultaneously, reduced the loss waste of the forest reserves; Product quality reaches national category-A particieboard Grade A standard.
The specific embodiment
The method of utilizing the bamboo bits to produce the bamboo shaving plate, it comprises the following steps:
Blanking---is dried---sorting---glue mixing------precompressed---hot pressing---the saw limit of mating formation; Wherein: glue mixing is to adopt a kind of low mol ratio modified urea-formaldehyde resin glue, adopts the applying glue of stirring-type air-flow glue spraying method.
The applying glue of described stirring-type air-flow glue spraying method, glue consumption 110kg ∕ cubic meter.
Described hot pressing pressure 2.0MPa, 170 ℃ of hot pressing temperatures, hot pressing time 20s ∕ mm.
The present invention has following features:
(1) mask-making technology: resin added 120KG ∕ cubic meter, table/core layer material proportioning 45/55,180 ℃ of hot pressing temperatures, particieboard particle 0.5-1.0mm.
(2) performance indications of product: MOR 17.5MPa, inner structure intensity 0.48MPa, burst size of methanal 5.5mg/100g, surface bonding strength 1.3MPa, density 750Kg/ cubic meter.
(3) utilize first the discarded object of green bamboo to produce the bamboo shaving plate, be widely used in building, cement model particularly, indoor and outdoor decoration plate; Packing, particularly container; The recombinant type engineering structural material of the industries such as car and boat.
(4) change traditional heat pressing process, adopt the secondary pressurized mode, in the situation that hot pressing temperature is constant, shortened hot pressing time and hot pressing pressure, effectively improved product quality and production efficiency.

Claims (3)
