1, physical methods
There are mainly high-temperature method, water immersion method, smoke method, air-conditioning method, far-infrared method, microwave method and ray method. The advantages of these methods are pollution-free and five-remains poison. Disadvantages are bamboo or bamboo products after treatment. If they are improperly stored, they may be re-infested with roundworms and molds. In addition, bamboo that is cut in the spring is vulnerable to insects, and bamboo that is felled in winter is not susceptible to insects. Therefore, bamboo cutting should be arranged as much as possible in the winter. In addition, bamboo materials after harvesting should be transported to the production site for use as soon as possible, or use insect repellent and mothproof treatment to reduce insect infestation and mildew.
2, chemical methods
There are coating methods, impregnation methods, cooking methods, fumigation methods, and pressurized injection methods. The advantages of these methods are good anti-mite and anti-corrosion effects and long time. The disadvantage is that some drugs are toxic, and they are easy to cause pollution to products and the environment. With the increasing awareness of environmental protection, environmental protection requirements and standards for bamboo insect repellents, preservatives, and fungicides are also increasing. For example, CCA, PCP, and other preservatives have been banned in Europe. CCB and CCF are mainly used. , and ACQ and other preservatives.
