Description

Temperature and humidity control-integrated special wood aging test box

Technical Field

The invention belongs to test equipment, and mainly relates to a temperature and humidity collection control special wood aging test box.

Background

The wood resource is used as a strategic resource for the economic development of China, plays an important role in the strategic practice of the sustainable development of China, China is a world with large wood demand, and the supply and demand of wood are very tight. With the wide application of wood materials, irreversible aging phenomena occur on the physical, mechanical and chemical properties of wood in the long-term use process. In addition, the external factors such as climate (temperature, humidity, ultraviolet rays and the like), environment, biology and the like can further damage the wood, and the aging phenomenon seriously restricts the efficient utilization and sustainable development of the wood. Despite the rapid development of the wood aging industry in recent years, the service life of wood is still one of the main problems to be solved urgently. The analysis of the aging performance of the wood can not only evaluate the weather resistance of the wood, but also adopt proper anti-aging measures to prolong the service life of the wood. At present, the wood aging test mainly adopts two modes: natural atmospheric aging method and artificial accelerated aging method. The manual accelerated aging method is not limited by time and place, the whole process of the whole wood aging test can be completed only by regulating and controlling the temperature, the humidity and the ultraviolet intensity in the wood aging test box, the test period is greatly shortened, and the test efficiency is greatly improved. However, the aging box in the existing market does not have an aging box special for wood, only can adjust one or two wood aging factors, and cannot comprehensively regulate and control the climate factor of wood aging, so that the special experiment box for wood aging with all-climate multi-factor and strong-pertinence temperature and humidity collection control is designed, and has important significance and value for researching aging test of wood, improving wood quality and prolonging the service life of wood.

Disclosure of Invention

Aiming at the specific problems in the prior art, the invention researches and designs a special test box for wood aging, which integrates temperature, humidity and ultraviolet intensity, can comprehensively evaluate the wood aging process and weather resistance by integrating three wood aging factors of temperature, humidity and ultraviolet intensity into one test box, and is simple and convenient to use.

The invention aims to realize that the temperature and humidity collecting and controlling wood aging special test box comprises an upper box part and a lower box part, wherein an inner box is arranged in the middle of the upper box part, an elevation frame and a heating pipe are respectively arranged on two sides in the inner box, a ventilation hole and an atomizing spray head are arranged on the upper side of the inner box, ultraviolet lamps are respectively arranged on two sides of the ventilation hole and the atomizing spray head, the elevation frame can be movably matched with a placing frame, a control panel is arranged above the inner box, and a right heat dissipation ventilating plate and a left heat dissipation ventilating plate are respectively arranged on two sides of the inner box.

Preferably, the upper box part can be in running fit with the box door, a box door handle is arranged on the right side of the box door, and the box door handle can form a running fit with a handle groove fixedly arranged on the front right side of the upper box part.

Preferably, the walking wheel is fixedly arranged below the lower box part, the front side of the walking wheel is provided with a front heat dissipation ventilating plate, and the right side of the walking wheel is provided with a water inlet a, a water inlet b and a water outlet.

The invention utilizes the simultaneous action of three wood aging factors, comprehensively and accurately simulates the actual environment of wood aging, and can simulate the wood aging environments of different places in different seasons by adjusting the temperature, the humidity and the ultraviolet illumination intensity in the control box, thereby obviously improving the accuracy and the test efficiency of the wood aging test.
