Problems solved by technology

[0003] However, due to the flammability of ordinary oriented strand board, its application in many fields is limited
Although the existing oriented strand board usually improves the flame retardancy by adding flame retardants, the process is often very complicated, or the cost is high due to the use of expensive flame retardants, and the flame retardancy cannot meet higher safety requirements

Embodiment 1

[0057] like figure 1 Shown is provided with the flaking machine of flame retardant spraying structure, and this flaking machine comprises: knife ring 1 and the blade 2 that is evenly distributed on the knife ring 1, the quantity of blade 2 is 48 ( figure 1 Three blades are drawn as an example, and the remaining 45 blades that are not drawn are evenly arranged on the knife ring 1);

[0058] The spraying structure includes: a flame retardant storage tank 3, a pressure nozzle 4 and a flame retardant delivery pipeline, and the pressure nozzle 4 is connected to the flame retardant storage tank 3 through the flame retardant delivery pipeline;

[0059] The injection angle of the pressure nozzle 4 is perpendicular to the blade of the blade 2, so that the angle between the nozzle and the blade is 90°. The number of pressure nozzles 4 is 10, and the pressure nozzles 4 are evenly distributed along the outer circumference of the knife ring 1, and the distance between the pressure nozzles...

Embodiment 2-21

[0067] Adopt the device that embodiment 1 provides, along with the rotation of planer knife ring, blade is planed to wood cutting (planing specification: width 5-40mm, thickness 0.4-0.8mm, length 100-180mm), at the same time, The flame retardant solution is evenly sprayed onto the planer along the direction perpendicular to the blade edge to obtain a flame retardant planer.

[0068] The spraying range of the flame retardant solution can cover all planks.

[0069] The temperature of the flame retardant solution is around 25±5°C;

[0070] The concentration of the flame retardant in the flame retardant solution, the adhesion amount of the flame retardant, the spraying amount (indicated by the pump flow rate), and the moisture content of the flakes before and after spraying the flame retardant are shown in Table 1.

[0071] Table 1.

[0072]

[0073] Note: When the pump flow rate reaches the maximum value in the table, there is an obvious liquid outflow phenomenon inside the ...

Embodiment 22

[0107] Example 22 Knife ring temperature monitoring

[0108] After shaving for 10 minutes in Example 2, the temperature of the knife ring was monitored by an infrared temperature detector immediately after the knife ring exited. Each batch of wood needs 4 knives, takes about 1 minute, and monitors 40 batches.

Abstract

The invention discloses a flaking machine with a flame retardant sprinkling structure and a flaking method. The flaking machine comprises a knife ring, knife blades and a sprinkling structure, whereinthe knife blades are distributed on the knife ring; the sprinkling structure comprises a flame retardant storing tank, one or two or more than two spray heads and a transporting pipeline; the spray heads is connected with the flame retardant storing tank through the transporting pipeline; and the spray heads are distributed on the periphery of the knife ring. When the flaking machine disclosed bythe invention is used for flaking, during flaking, a flame retardant is sprinkled at the same time; and during flaking, various flame retardant solutions are sprinkled, so that beyond all expectation, an excellent coverage rate of the flame retardants can be obtained, and the temperature lowering range of the knife ring and the knife blades is further increased.

Description

technical field [0001] The invention belongs to the field of wood processing, and relates to a machine for wood processing, in particular to a planer provided with a flame retardant spraying structure and a flame retardant spraying method. Background technique [0002] Oriented strand board (OSB) is a kind of oriented structural board made of poplar, pine and other wood as raw materials, processed into shavings by special equipment, dried, glued, oriented paving, hot-pressed and other processes. The surface flakes are arranged vertically, and the core flakes are arranged horizontally. This criss-cross arrangement reorganizes the wood grain structure, completely eliminates the influence of wood internal stress on processing, and makes it have excellent processability and moisture resistance. OSB has a directional structure inside, no joints, no gaps, no cracks, good overall uniformity, and high internal bonding strength, so OSB has been widely developed in recent years. [...
