Problems solved by technology

However, high-temperature heat treatment is difficult to completely discharge or at least basically discharge the oil in wood, so that the outdoor wood after high-temperature heat treatment still often has the problem of oil leakage; at the same time, high-temperature heat treatment makes tree knots easier to crack and fall off
For example, paragraphs 5 and 13 of the patent specification record that problems such as tree knot falling off, cracking, and paint falling off have never been solved, and high-temperature heat treatment aggravates the above problems, and can only rely on relevant technical information related to later repairs.

Embodiment 1

[0034] Embodiment 1: A method for deoiling outdoor materials. The material to be processed is southern pine, and the specifications are commercially available boards. It is carried out in a carbonization kiln, and includes the following steps in turn,

[0035] (1) Steps of oil-water mixing treatment: the treated material is dry wood, and any method of moisture absorption and callback by the prior art (for example, placing the treated material in an environment of 30°C / 96%RH for callback treatment) will The moisture content of the material to be treated is adjusted to 25 (±2)%; in this step, rosin, turpentine, resin and enough water are mixed to reduce their boiling point and volatilization temperature.

[0036] (2) Steps of high temperature heat treatment: including the heat treatment stage and the drying treatment stage; first, in the heat treatment stage, keep the temperature difference between dry and wet bulbs less than 1° until the wet bulb temperature rises to 105 (± 2) ℃...

Embodiment 2

[0038] Embodiment 2: a kind of method of outdoor material deoiling treatment, the processed material is sylvestris sylvestris, and the specification is commercially available plate, carries out in carbonization kiln, comprises the following steps successively,

[0039] (1) Steps of oil-water mixing treatment: the treated material is wet wood, and the moisture content of the treated material is adjusted to 26 (±2 )%.

[0040] (2) Steps of high temperature heat treatment: including the heat treatment stage and the drying treatment stage; first, in the heat treatment stage, keep the temperature difference between dry and wet bulbs less than 1° until the wet bulb temperature rises to 110 (± 2) ℃, keep the wet bulb temperature And raise the dry bulb temperature to 180 (± 2) ℃, keep and treat at the highest temperature for 3.0 hours, so as to realize the deoiling treatment of the treated material; then in the drying treatment stage, keep the wet bulb temperature at 110 (± 2) °C, re...

Embodiment 3

[0042] Embodiment 3: A method for deoiling outdoor materials. The processed material is Scots pine, and the specifications are commercially available boards. It is carried out in a carbonization kiln, and includes the following steps in turn,

[0043] (1) The steps of oil-water mixing treatment: the treated material is dry wood, and any method of moisture absorption and callback by the prior art (for example, placing the treated material in an environment of 36°C / 92%RH for callback treatment) will The moisture content of the treated material is adjusted to 25 (± 2)%.

[0044] (2) Steps of high-temperature heat treatment: including the heat treatment stage and the drying treatment stage; first, in the heat treatment stage, keep the temperature difference between dry and wet bulbs less than 1° until the wet bulb temperature rises to 115 (±2) °C, and keep the wet bulb temperature And raise the dry bulb temperature to 170 (± 2) ℃, keep and treat at the highest temperature for 3.5 ...

Abstract

The embodiment of the invention provides an outdoor material deoiling treatment method. The outdoor material deoiling treatment method comprises the step of high-temperature heat treatment and furthercomprises the step of oil-water mixed treatment before the step of high-temperature heat treatment. The step of oil-water mixed treatment is the step for adjusting the water content of a treated material to be 20-30%. The situation that the quality problem of oil leaking of outdoor materials occurs in the using process can be reduced or avoided, and the cracking and falling-off situations of burls in the treatment process and the using process are reduced or avoided.

Description

technical field [0001] The application belongs to the technical field of wood modification treatment, and specifically relates to a deoiling treatment method for outdoor wood. At the same time, the application also relates to an antiseptic treatment method using the deoiling treatment method as a pretreatment method. Background technique [0002] Outdoor materials, such as outdoor floors, plank roads, and exterior wall panels of wooden houses, use pine species, the main types of which are sylvestris sylvestris, southern pine, and red pine. Pine wood contains a large amount of rosin, turpentine, resin and other components, which makes pine wood often suffer from oily quality problems due to sun exposure and temperature rise during use. In particular, there are many knots on the pine wood, and the knots contain relatively more rosin, turpentine, and resin components, and they are easy to crack and tend to fall off from the wood body, so the rosin, turpentine, and Components s...
