Bamboo and wood products refer to products made from bamboo products processing raw materials, mostly for daily necessities, such as bamboo baskets, bamboo sieves, bamboo hedges, hoes, bamboo steamers, oysters, bamboo rafts, bamboo rafts, bamboo rafts. , baskets, bamboo poles, bamboo chopsticks, bamboo brooms, bamboo rafts, bamboo rafts, bamboo rafts, bamboo rafts, bamboo mats, bamboo beds, bamboo stools, bamboo chairs, bamboo loungers, chopping boards, mats, tea coasters, curtains, etc., in recent years To compare the popular bamboo flooring and bamboo furniture, there are some folk crafts with higher value, such as bamboo carvings.
The wooden handicraft production is very particular about the selection of bamboo materials. Generally, after entering the winter, before the spring, when the weather is fine, enter the mountain, prepare two large iron pans, some caustic soda, bamboo knives, axe, hoe and other tools. More than a year, too tender and too old are not desirable. When selecting bamboo, only take the middle section of bamboo, five or six sections, choose the appearance of the flat, no flaws. After cutting down, you should also pay attention to protection. Once there is injury, there is no way to recover. For the pen holder, you can choose the length near the root, first saw the length, the length of the pen holder is generally 12 cm up and down, fifteen or more than six centimeters is not easy to use. The arm can be selected as long as possible. After the bamboo is cut, immediately set the pot, boil the water, add caustic soda, and simmer for a long time. For example, if you are in Guangdong, you should constantly remove the bamboo juice from the water. After a few hours, take the bamboo tube and the bamboo piece out of the heat, wipe off the bamboo juice on the surface, and immediately put it into another boiling water pot and continue to cook. Each pot takes about three hours. After the time is up, don't rush to take out. After the water is getting warm, wipe off the surface and cover it with thick paper on the side with bamboo skin to avoid scratching. Every time you cut the bamboo, try to take more, because the loss to the back is greater, the focus of the selection is:
After the bamboo is returned home, spread it out for a few days, be careful of moisture and mildew. Then take the winter sun and sun! Always drying until the spring, during the period of cracking and other problems, abandoned. After the spring. Take the dried bamboo and store it in a cool dry place, pay attention to ventilation. Take out the inspection every year and put it for more than three years. If it is not bad, you can use it with confidence. This kind of material is as strong as jade and turns red for a long time. It is a rare treasure.
A bamboo product pattern making method, according to different levels of bamboo used in bamboo products, the first layer is shaving (including head blue), the second layer and the third layer are two green, respectively, using different methods to make patterns, shaving ( Including the head green), the bamboo product pattern is made by placing the bamboo product in a magnetic field with a magnetic induction intensity of 0.5-1.5T, and covering the bamboo product with an art mold (female mold) which is resistant to acid and deformation and has various patterns. 5-65% (by weight concentration) of various concentrations of nitric acid (or a mixture of nitrate and other strong acid) or a mixture of sulfuric acid or nitric acid to spray the pattern of the mold, the acid solution is cut through the engraving pattern of the male mold On the bamboo piece, the above acid can also be directly used for painting on the product without using a mold, and then baked at a temperature of 80 ° C - 12 ° C for 3-5 minutes to cause esterification reaction between the acid liquid and the bamboo fiber, thereby making the bamboo product It shows a beautiful pattern of different shades of light; the pattern of the two green bamboo products is made by placing the bamboo products in a magnetic field with a magnetic induction of 0.5-1.5T. Eclipsed and engraved with various patterns of art molds (male mold) covered in two green bamboo products, and then the following processes: a, spray 1% (% by weight concentration) of sulfonated succinic acid dioctine to the entire bamboo products and mold Ester sodium salt rapid penetrant; b, followed by spraying a strong acid or alkaline or salt solution, solution concentration depends on the pattern requirements; c, spray fixing agent hexahydro-1,3,5-tripropylene Acyl triabenzene (concentration: 1% by weight); d, spray nitro varnish; e, remove the mold, to obtain a pattern of dark colors around the pattern, the pattern of bamboo (seat) products.
