As early as the neolithic liangzhu culture site, there have been bamboo woven utensils. Nowadays, it is still widely used to put all kinds of food, such as bamboo basket, bamboo basket, bamboo basket and so on. In addition to this, bamboo is also used as tableware, such as chopsticks, below the jiangxi bamboo products manufacturers to tell you the composition and structure of bamboo.
The bamboo material used for packaging industrial products is mainly the underground stem of bamboo (commonly known as bamboo rod), which is composed of bamboo (skin), bamboo meat (fiber bundle and basic tissue) and pith. Along the bamboo stem longitudinal at a certain distance there is a ring protruding, called the bamboo node, the bamboo branch is born on the node. Bamboo joints can increase the stiffness of bamboo stems. Between the two bamboo called internodes, near the ground part of the shortest internodes. The bundle of fibers is the main part of the bamboo material, which is a channel for transferring water and nutrients and presents many spots on the cross section of the bamboo. Fiber bundle can be divided into catheter, fiber, sieve tube and cell cavity. Bamboo green part of the fiber bundle contains more lignin, dense distribution, strength than wood several times higher. Thin fiber bundle points near the marrow of cloth, strength than wood. Therefore, the strength of each part of the bamboo increases gradually from the inside out along the direction of the radius of the cross section.
The organic composition of bamboo is similar to that of wood, mainly composed of cellulose (about 55%), lignin (about 25%) and hemifibroin (about 20%). But hemicellulose composition is almost all polypentose, and polyhexose content is very small.
The organic composition of bamboo varies with bamboo age and bamboo wall position. There was significant difference in lignin content between bamboo shoot and mature bamboo. The growing bamboo is in different lignification stages from the base to the top. The lignification in each segment is carried out from the top down and horizontally from the inside out. The lignification of bamboo poles is completed within one growing season, and no changes occur thereafter. Within one year of formation, the proportion of lignin and sugar in bamboo wood changes, and the chemical composition is quite stable after that.
