What is a High-frequency Wooden Formwork

图片
The   wooden construction templates   can be classified into different materials and types according to their prices, which vary from high to low: film-faced plywood formwork, pine wood formwork, eucalyptus wood formwork, pine and eucalyptus combination formwork, pine and poplar combination formwork, and poplar wood formwork. Generally, a higher price of the building wood template indicates a higher number of usage. Generally, the average usage of wooden construction templates is around 6 times. When it exceeds 8 times, it is considered a high usage template. The reasons why the usage of wooden construction templates is low. Let’s summarize the reasons why high usage templates cannot be achieved. 1. The wooden template has poor quality due to the use of inferior materials. 2. During the construction period, improper use may result in the dropping of bricks, stones, wood chips, and other debris that are not promptly cleaned, which can scratch the surface of the construction tem...

5 Common Drawbacks of Wooden Construction Templates

图片
Today, we'd like to introduce to you the common 5 drawbacks of   wooden construction templates . The quality issues of wooden construction templates are relatively significant in engineering projects. Let’s analyze the 5 major defects commonly found in construction templates, so that you can have a deeper understanding of this type of construction material. 1. Deformation: The deformation of wooden construction templates is caused by warping and distortion resulting from processing, monotony, and storage. The deformation of wooden construction templates has a certain impact on quality. 2. Decay: Under certain conditions, wooden construction templates can be damaged by wood fungi and bacteria, which can cause changes in color and structure of the wood, making it soft and fragile with the appearance of holes, powder, or sponge-like texture. This is a manifestation of decay in wooden construction templates. 3. Discoloration: The discoloration of wooden construction templates is caused...

The Difference between Particle Board and Solid Wood Particle Board

图片
Particle board   and solid wood particle board are both artificial board materials, and there are some differences between them. Here are some main differences between them: 1. Different raw materials: Particle board is made from wood chips and shavings, while solid wood particle board is made from wood, small wood pieces, or wood waste. 2. Different density: Particle board has a lower density, usually between 0.8-1.2g/cm3, while solid wood particle board has a higher density, usually between 0.9-1.3g/cm3. 3. Different manufacturing processes: Particle board is made by mixing the wood chips and other raw materials together, and then pressing them into sheets. Solid wood particle board is made by mixing wood, small wood pieces, or wood waste materials together, and then pressing them into sheets. 4. Surface treatment varies: The surface of particle board is usually treated with surface coatings, while the surface of solid wood particle board is typically treated using methods such a...

Assessment of the Quality of Particle Board

图片
Particle board , also known as chipboard, is a type of engineered wood board produced by cutting fast-growing timber and wood chips into certain-sized fragments. After drying, it is mixed with glue, hardening agents, waterproofing agents, etc., and pressed under specific temperature and pressure to form a board. The arrangement of particles is not uniform. Although particle board is also called chipboard, it is not the same as solid wood particle board. Solid wood particle board has a similar manufacturing process to particle board but is far superior in quality. 1. From the appearance, the size and shape of the wood chips in the central area of the cross-section should be observed. Usually, the length is between 5-10mm. If it is too long, the structure will be loose, if it is too short, the resistance to deformation will be poor, which means the static flexural strength does not meet the standard. 2. The moisture resistance of engineered boards depends on their density and moisture re...
