Description

Technical Field

[0001] The utility model relates to a forestry product aging test box, in particular to a detachable forestry product aging test box capable of integrating temperature, humidity and light regulation, and belongs to the technical field of environmental simulation equipment for product testing. Background Art

[0002] In recent years, wood resources have been scarce, but forestry residue resources are relatively abundant. Using residues to make sanitary chopsticks, tool handles, core strips of joinery boards and composite fiberboards can save a lot of logs, reduce costs, and greatly improve the utilization rate of forest resources. Forestry residue products also have good ecological benefits: for example, collecting residues in felling areas can reduce the spread of pests and diseases; giving tree seeds more opportunities to contact the soil, thereby promoting forest renewal; and facilitating forest fire prevention work.

[0003] Forest products are biomass materials. They are environmentally friendly and have typical biological characteristics. They are greatly affected by temperature, humidity and light. The aging resistance of forest products is an important indicator to measure their performance. Therefore, it is necessary to evaluate the aging resistance of various forest products and obtain accurate data to predict their application areas, performance and life. At present, aging tests mainly adopt two methods: natural atmospheric aging and artificial accelerated aging. Natural atmospheric aging is the most direct and reliable method to evaluate product performance, but the disadvantage is that it takes a long time, the environmental conditions are difficult to control, and it is impossible to separate the effects of various environmental factors (temperature, humidity, light intensity) on product properties. Artificial accelerated aging is not limited by time and place. It only needs to adjust the temperature, humidity and ultraviolet intensity in the aging test box to complete the entire process of forest product aging test. The test cycle is short and the test efficiency is high. At present, the aging test boxes on the market are mainly used for aging tests of electronic components and plastic products. There is no special aging test box for forest products represented by materials such as wood fiber and wood fiberboard. In addition, the aging test chambers on the market have relatively single functions and can only perform aging tests on one variable (temperature, humidity, light intensity, ozone concentration, etc.), which cannot simulate natural conditions well, and most product sockets are fixed. Based on the above situation, it is necessary to study a detachable multifunctional aging test chamber specifically for forestry products. Utility Model Content

[0004] In order to overcome the above-mentioned deficiencies of the prior art, the utility model provides a detachable forestry product aging test box with integrated temperature, humidity and light regulation.
