How to reflect the stability of tasteless E0 grade environmental Particleboard
source:www.gq31.cn Time:2025-03-31
The stability of tasteless E0 grade environmental particleboard is mainly reflected in the following aspects:
1. structural uniformity: it is made of wood or other lignocellulosic materials after screening, drying and other pretreatment, applying adhesive and pressing through high temperature and high pressure. This production process makes the shavings in the particleboard evenly distributed, compact structure, and the physical properties of each part are relatively consistent, so as to ensure the stability of the board in different parts is the same, and it is not easy to have local deformation or damage.
2. moisture resistance: Although particleboard is made of wood materials, additives such as waterproof agent are usually added in the production process to make it have certain moisture resistance. The moisture-proof performance of tasteless E0 grade environmental particleboard is relatively good, which can resist the impact of the wet environment on the board to a certain extent, and reduce the expansion, deformation and other problems caused by moisture. For example, in relatively humid environments such as kitchens and bathrooms, if we use tasteless E0 grade environmentally friendly particleboard with qualified quality and do a good job in surface protection, it can maintain stable performance for a long time.
3. dimensional stability: tasteless E0 grade environmentally friendly particleboard has good dimensional stability when temperature and humidity change. This is because its production process and material characteristics make the plate keep its original shape and size as much as possible under different environmental conditions, and it is not easy to have obvious expansion or contraction. Generally speaking, the tasteless E0 grade environmental particleboard produced through strict quality control has a small size change rate when it changes within the normal indoor environmental humidity (40%-60%) and temperature (15 ℃ -25 ℃), which can meet the dimensional accuracy requirements of furniture and other products.
4. mechanical stability: it has certain strength and rigidity, and can withstand certain pressure and weight without deformation. The mechanical properties of odorless E0 grade environmental particleboard, such as static bending strength and modulus of elasticity, can generally reach high standards, which makes it stable to support items when used as shelves and panels of furniture, and is not prone to bending, fracture and other phenomena, ensuring the structural stability and service life of furniture.
