  • Detail

Plywood is literally a board made of three layers of thin wood pasted. It is formed by pressing after gluing the thin wood in a heated or unheated environment. It is one of the most common and widely used plywood

at ordinary times, I believe many people have noticed that many furniture in their homes are not made of a whole piece of wood. People who carefully observe it will find that many furniture boards are plywood bonded by many layers of boards. Plywood plywood is one of the most common and widely used plywood. So do you usually know about plywood? Today, Xiaobian will introduce you to the relevant knowledge of plywood

advantages and disadvantages of plywood

1, advantages

plywood is made of different veneers pasted and pressed, so plywood can save a lot of wood. Today, with the increasing lack of forest resources, plywood is undoubtedly a very good choice. Plywood is made of three-layer plates. Compared with other single-layer plates of the same thickness, plywood tends to have greater strength, its load-bearing capacity and bending resistance are relatively strong, and it has good heat insulation and sealing performance

2. Disadvantages

due to the need for adhesive bonding of plywood, it is inevitable to use glue made of chemical raw materials, which paves the way for the safety of plywood. Adhesives contain formaldehyde, so the formaldehyde content of plywood has become an important factor endangering people's health. In addition, some paints in the furniture manufacturing process also contain formaldehyde, so we should pay attention to the formaldehyde content when buying plywood or furniture made of plywood

safety problems of plywood

plywood is made of three layers of wood veneers of different materials. Because adhesives containing formaldehyde are used in the production, furniture made of plywood will release formaldehyde. In addition to causing respiratory and nervous system diseases, such as cough, sore throat, chest tightness, dizziness and nausea, limb weakness, dyspnea, sleepiness and other symptoms, formaldehyde can also induce the occurrence of nasal cancer, throat cancer, skin cancer, leukemia and other cancers. Generally, the release time of toxic gases is 1-10 years, especially in the first year. During this period, toxic gases volatilize rapidly, release a high amount, and do serious harm to human body

because indoor formaldehyde and other harmful gases will damage human health, it is best not to buy furniture made of synthetic board, especially in families with children. If you have board furniture at home and feel that the smell is particularly strong, you'd better ask a qualified monitoring organization to monitor whether the indoor air environment meets the standard. In addition, photocatalyst products can also be used to reduce the harm caused by harmful gases

tips for selecting plywood

there are positive and negative differences between plywood. When selecting, the wood grain of the plywood should be clear, and the front side should be smooth without roughness and sluggish feel. There shall be no damage, bruise, hard injury, scar and other defects, and there shall be no degumming on the cutting surface. Some plywood is made by sticking two veneers with different lines together, so attention should be paid to the tightness of the joint of the plywood in the selection. When selecting the plywood, if the sound is crisp when tapping each part of the plywood by hand, it proves that the quality is good. If the sound is stuffy, it means that the plywood has been scattered

difference between plywood and integrated board

1. Plywood refers to a common plywood made of three layers of thin wood stuck together in different texture directions. The integrated board is glued wood

2. Plywood is made of three layers of wood veneers of different materials. Therefore, adhesives are used in production, and formaldehyde is the most harmful substance in adhesives. Formaldehyde can cause respiratory and nervous system diseases, such as cough, sore throat, chest tightness, dizziness, nausea, limb weakness, dyspnea, sleepiness and other symptoms. More serious, it can induce nasal cancer, throat cancer, skin cancer, leukemia and other cancers

3. Using small-diameter materials as production raw materials, laminated wood is cut into plates through logs, dried, made into square strips, broken materials, selected materials, finger joint, splicing, subsequent treatment and a series of processes to make wood with a certain width, thickness and length. It is a new type of base material used in the construction industry, furniture and decoration industry. It has the characteristics of high strength, 1.5 times that of natural solid wood, good fire prevention and high thermal insulation performance

Xiaobian conclusion: This is the relevant knowledge about plywood. I hope it will be helpful to you. If there is anything else you don't understand, you can leave a message to Xiaobian below. We will answer it for you as soon as possible, and we will provide you with more complete, more detailed and updated information
