The state strictly controls the anti-corrosion industry and the prospects of anti-corrosion timber

In order to speed up structural adjustment of the wood preservation industry, strengthen environmental protection, comprehensively utilize resources, standardize industry investment behavior, and stop blind investment and low-level redundant construction, the Ministry of Industry and Information Technology's Raw Materials Industry Department recently issued the “Entry Requirements for Wood Preservative Industry” ( Hereinafter referred to as "conditions").

The "Conditions" set specific requirements for wood preservatives and wood preservatives from the aspects of enterprise construction conditions and layout, scale technology and equipment, environmental protection and comprehensive utilization of resources, product quality, safety and health and social responsibility, and supervision and management. New, reformed, and expanded enterprises will increase their access thresholds, and propose rectification within a time limit for enterprises that have already established plants but fail to meet standards, gradually standardize the production and operation order of wood preservation enterprises, eliminate backward production capacity, and promote the healthy development of the wood preservation industry.

The "conditions" will be implemented on October 1. Before the project is put into production and during normal production, local industrial authorities will implement the conditions of access for wood preservative enterprises within the jurisdiction. The Ministry of Industry and Information Technology will announce the list of companies that meet the conditions for access, accept social supervision and implement dynamic management, and the announcement management measures shall be formulated separately by the Ministry of Industry and Information Technology.

Rapid development of hidden dangers Wood preservation industry includes wood preservatives and preserved wood. China's timber anti-corrosion industry started from railway sleepers. Before 2000, it was mainly used to produce anti-corrosion sleepers and poles. After 2000, with the introduction of foreign new types of wood preservatives and preserved wood, wood protection products have evolved from a single to a diversified direction, and the wood preservative industry has ushered in a period of rapid development. In particular, since 2006, the market has maintained rapid growth, and preserved wood has been widely used in landscapes, residential greening, tourist attractions, and home decoration.

At present, wood preservative enterprises have grown from more than a dozen in 2000 to more than 340, but their production scale is generally too small, technological processes are backward, inspection and testing methods are not available, and non-compliant products enter the market. These problems not only affect the products Quality and industry reputation are more likely to endanger people's health and life safety.

Some wood preservative companies are indifferent to the quality, environmental protection, and safety awareness during the production of copper-chromium-arsenic wood preservatives, wood preservatives and their use, and they put on the market preservative-grade wood with unacceptable amounts of preservatives or excessive toxic and hazardous substances. This kind of preserved timber flows to civil buildings, public leisure and children's entertainment places, leaving hidden safety hazards.

The development prospects are promising. At present, the application of antiseptic timber has become more and more extensive. Outdoor garden anti-corrosion wood floors, wood preservatives, wood preservative pavilions, log cabins, wooden structure houses, wooden house villas, etc. are now very popular cutting-edge products, and are being accepted and used by more and more people. Green environmental protection will become an increasingly mainstream lifestyle in the future. The wooden structure houses use the natural material as the structure main body, the auxiliary building materials also does not contain the harmful material to the human body, is the ideal green living space, causes people to enjoy the health environmental protection benefit unconsciously.

In countries such as Europe and the United States, wood frame construction is popular. According to statistics, in 1998, there were approximately 1,138,000 newly-built single-family villas in the United States, of which more than 90% used wooden construction. In China, we still find it easy today to find civil and commercial timber-framed houses built over 100 years ago.

Wood is the only building material that can be recycled. In respect of energy consumption, greenhouse gas, air and water pollution, and ecological resource exploitation, the environmental protection of wood structure is much better than that of brick-concrete structure and steel structure, and the material has good ventilation and easy to keep indoor air fresh. Is a recognized green building. Wood-framed houses do not pollute the environment during the construction process, and the natural affinity benefits the health of occupants. This is unmatched by other structural houses. This is an environmentally friendly structural house that countries around the world strongly encourage. The average life span of timber-framed residential dwellers is 9 to 11 years older than that of reinforced concrete dwelling dwellers. The wooden villa environment is a kind of protection that is beneficial to human health.

In people's traditional consciousness, the moisture-proof and anti-corrosion properties of wood are poor and it is easy to affect the service life of a house. In fact, after the technical treatment of preserved wood, it can well solve people's concerns about anti-corrosion, but also extend the life of wood. Facts have proved that the use of preserved wood is a very stable, long-lived, durable material.
