Which Methods Can Be Used To Carry Out Aging Experiments On Wood-plastic Flooring

Detecting the anti-aging degree of wood-plastic floor is an important step in the process of product development. If it is detected by natural and old methods, it will take a long time, which is unfavorable to product development. The commonly used method is laboratory accelerated aging. Natural climate ageing refers to direct exposure to sunlight and other climatic conditions, which is a method of directly evaluating the weatherability of materials.

The advantages of natural climate ageing are good agreement with wood-plastic floor ageing, simple operation, low absolute cost, etc. The disadvantage of natural climate ageing is long ageing period, different samples have different sensitivity under different conditions, and the results of determination are only applicable to specific exposure test sites; the latter has short time, has nothing to do with site, season and regional climate, and the measured data can maintain a good weight. Renaturation and other advantages. Laboratory accelerated aging tests mainly include thermal aging, freeze-thaw accelerated aging, ozone aging, salt spray aging, artificial climate aging, corrosion and erosion aging, among which freeze-thaw accelerated aging, corrosion and erosion aging are the main research.

With the application of wood-plastic floor more and more widely, the climate conditions are also very different. In northern China, for example, rainwater is often wetted in midsummer and exposed to sunshine above 30 C, while in winter, it is necessary to withstand the severe cold below - 20 C. Wood-plastic flooring used near the water zone will undergo more frequent wet, cold, frozen and hot cycles. The repeated cold-heat and freeze-thaw cycles are a severe test for the performance of wood-plastic flooring, and often determine the service life of products.

Wood-plastic floor is a new type of green and environmental protection composite material which has appeared in recent years. The raw materials used in wood-plastic products are all wood and crops which can be used as waste plastics and waste gas. They do not contain any harmful ingredients and can be recycled and used sustainably. They can be called new composite products of environmental protection, energy saving and resource recycling in a real sense. They not only conform to the concept of environmental protection and energy saving, but also follow the sustainable development policy of our country. This is also the reason why the application of wood-plastic flooring is gradually expanding, and in the future it may replace solid wood flooring as the main decoration building materials.

Wood-plastic floor combines the characteristics and advantages of plastic and wood fiber, and has good waterproof, moisture-proof, fire-proof, insect-proof, anti-static, anti-ultraviolet and other good properties. Long service life, easy installation. But at present * common wood-plastic floor is still installed in outdoor landscape, parks and other areas, family decoration is still relatively rare, why?

Professionals in the industry pointed out that wood-plastic floor because of the good integration of plastic and wood fiber, the ratio of the two, the choice of wood flour, additives and equipment and other issues are urgently to be solved, the technical requirements are relatively high, so the current price of wood-plastic floor is still slightly expensive. However, with the continuous advancement of technology and the continuous promotion of the market, in the next 5-10 years, the price of Plastic-wood flooring will be more people-friendly, and very hopeful to replace solid wood flooring in an all-round way, become a major trend of the country to promote low-carbon environmental protection economy.
