Rizhao Lanshan Pine Strip Packaging Tray Special Wood Processing Factory

Description :

　　In the Rizhao wood market, wood undergoes photosynthesis to proliferate fiber cells, extending branches to receive as much sunlight as possible and growing leaves to form a wide area. Usually, wood without knots has a higher evaluation, but

　　During the production of pine strips, manufacturers generally classify sizes such as 6 * 1.7 as wood defects. "Knots" are essential parts of the tree's growth process, derived from the trunk. Wood without knots does not exist. The knotless part only accounts for a small part of the entire wood and is a rare part of the wood. The process of its generation differs between deciduous and broad-leaved trees, and it has a significant impact on the strength and use of wood

　　Most coniferous trees have a trunk that extends upwards, with small branches extending horizontally in a spiral shape on one side of the tree, gradually growing. This horizontal branch

　　Branching from the tree core, pseudo trees also have cases where the woody part of the trunk covers the surface of the bark, while the bark of the small branches remains in the trunk.

　　It will form a 'dead eye' (as shown in the bottom left picture of the factory)

　　After this part is dried, the collection of dead joint eyes will increase, and after detachment, circular holes will form in that area. Dead eye is a serious defect in wood. If dead knots appear on the straight wood grain surface, the length of this water material will be divided into two. The dead eye lacks the strength of wood at all

　　Trees take root underground within a roughly equivalent range of their branches and leaves. Coniferous trees grow small branches, and the underground roots do not expand horizontally, making it difficult to form independent trees and suitable for growth in clustered forests. The branches and leaves growing in coniferous forests lack sunlight and yield to nature, causing the trees to extend upwards. Trees that lose their lower nucleus and extend upwards during childhood have slight nodes, which can produce a large amount of round logs with good quality.

　　On the contrary, trees on the outer edge of the forest will produce more nodes when their branches and leaves extend below the trunk. These trees growing on the outer edge of the forest are called "endwood" and are rated as low grade. In areas with heavy snow, the shoots will be folded by the heavy snow and corroded, leading to the formation of trunk air conditioning.

　　The ketone leaf tree grows on the outside of the trunk and does not expand its branches and leaves in a Y-shaped manner like coniferous trees. If the school leaves are separated into parts and made into sawn wood, the wood parts of the nodes and trunk are organically combined, and even after drying, they will not fall off.
