Children's desks are indispensable tools for children to learn, read, and surf the Internet. Suitable children's desks not only improve children's learning efficiency, but also help children's healthy growth and prevent hunchback situations. There are many kinds of materials for making children's desks. So, what kind of material is good for children's desks? Let's take a look at the introduction made by Zhoujia Mansion . What material is good for children's desks? First, solid wood material: The study table of solid wood material is generally used by middle school students or used at home. The study desks that consider environmentally friendly solid wood materials will not be mass produced, and the cost is relatively high. Xiaobian suggested that parents can give priority to solid wood materials when they buy school desks for their children. After all, the environmental performance of this material is higher. Even if the school uses a solid wood desk, it is not a combination of metal and plastic materials. The cost will be very high. Second, the plate material: China implements nine-year compulsory education, so in primary school, teaching quality and learning environment are more valued. In universities, schools will consider the practicality and durability of the study desk, so generally They are all study desks with a combination of sheet metal and metal. For example, solid wood particle board, wood-based board and the like are desk tops, and metal table legs are fixed on the ground for durability. Third, plastic material: If it is a plastic material for kindergarten, there will be more study desks, because children are more naughty, and inevitably, the study desk with plastic materials will be safer and the corners of plastic products. They are relatively sleek and light in weight, so most kindergartens use plastic study desks. Maybe you will ask the plastic material of the study desk to release a higher amount of formaldehyde, will it have a certain impact on the health of the child? In fact, this problem does not have to worry, the release of formaldehyde with analytical plastic products as long as the country has reached the national Within the prescribed scope, it will not have much impact on the health of the child. The above is a good introduction to the materials of children's desks. It can be seen that children's desks with different materials have different characteristics. Parents and friends can choose according to the children's situation. But in terms of safety and health, solid wood children's desks are the safest and most environmentally friendly, but the price is also the most expensive.

When the rigging is used in conjunction with the beam, the shackle can be used to connect the rigging with the lug plate at the lower part of the beam instead of the lifting ring, which is convenient for installation and disassembly. Shackles are widely used connection tools in lifting operations, and are mainly used for connection parts that are often installed and disassembled in hoisting. D-type shackle is mainly used for single-limb rigging; B-type shackle is mainly used for multi-limb rigging.
