Melamine Film Faced Plywood

Black construction formwork, also known as film-coated formwork or fair-faced board, has a preliminary panel layout process similar to red boards, but its surface uses film-coating technology, with both sides covered with black or red film paper made from special adhesive. This film paper makes the surface of black construction formwork smoother and more even, and it can be used more times than construction red-face templates and phenolic mirror boards of the same thickness. The manufacturing process of black construction formwork is relatively complex, so its price is higher than the other two types of formwork. Its surface is a layer of black adhesive film paper, and if there are quality issues with the core board, they will be directly reflected on the surface, making it easy to inspect the quality of the formwork. Most black construction formwork has waterproof and anti-corrosion properties and can be used in relatively complex environments such as hydropower stations, dams, bridges, high-rise buildings, and subways. It is recommended to choose black film-coated construction formwork, as it performs better than red construction formwork.

Red and black construction formworks do not differ in functionality; they are both used as formwork for cast-in-place concrete structures in construction projects. The formwork structure mainly consists of three parts: panels, supporting structures, and connectors. The panels are in direct contact with the freshly poured concrete, the supporting structures bear the panels, concrete, and construction loads to ensure the stability and integrity of the formwork, and the connectors are components that connect the panels with the supporting structures to form a unified whole.

Construction formwork refers to the molds and supports used for pouring and shaping concrete. Based on the material properties, it can be divided into construction formwork, construction plywood, film-faced boards, multilayer boards, double-sided laminated boards, double-sided film-faced construction formwork, and so on. According to construction process conditions, construction formwork can also be classified into cast-in-place concrete formwork, pre-assembled formwork, large formwork, jump formwork, etc. As a new type of formwork, wood-plastic construction formwork has advantages such as light weight, high impact resistance, easy assembly, high turnover rate, smooth surface, non-absorbent, mold-resistant, acid and alkali resistance, crack resistance, large panel size, fewer joints, and the ability to be cut, nailed, or customized to any length.

In practical application, the lifespan of construction formwork depends on the usage conditions and maintenance. The lifespan of a single board may vary depending on factors like frequency of use, construction environment, and degree of maintenance. Generally, high-quality wood-plastic construction formwork can be reused multiple times, potentially more than 10 times. However, the specific number of uses should be determined based on actual conditions. Nevertheless, using high-quality, durable formwork can significantly reduce construction costs and improve work efficiency.

It is worth noting that although red and black construction formwork are functionally similar, they differ significantly in appearance and color. These color differences may affect the overall visual effect at the construction site but do not impact the performance of the formwork. Therefore, the choice of color should be based on project requirements and the designer's preference.

In summary, red and black construction formwork are functionally identical; both are used as formwork for cast-in-place concrete structures in building support projects. In practical use, the lifespan of the formwork depends on usage and maintenance, while color differences primarily affect the overall visual appearance of the construction site.

Differences Between Black Formwork and Ordinary Formwork

1. Black formwork has significant advantages over ordinary construction formwork. It is lightweight, comes in large panels, does not warp, deform, or crack, has good water resistance, and a long service life. It is especially suitable for high-rise buildings and bridge construction. For fair-faced concrete, it produces smooth and aesthetically pleasing surfaces, eliminating the need for secondary wall plastering, allowing direct surface decoration.

2. Black formwork has strong corrosion resistance and will not stain the concrete surface. It can be processed into various shapes of formwork according to construction needs.

3. The various advantages of black formwork make it more suitable for construction compared to ordinary formwork:

(1) Ensures that its position, shape, and dimensions fully comply with the design requirements.

(2) Has sufficient load-bearing capacity and stability to withstand various loads encountered during construction.

(3) Simple structure, easy to install and dismantle, flexible to use. It can meet requirements for rebar tying, is suitable for centralized manufacturing, saves raw materials, improves efficiency, speeds up work, and meets the requirements of subsequent procedures.

Precautions for Storing Construction Formwork

1. When storing or transporting construction formwork, care must be taken to avoid impacts, scratches, or drops, as these can affect the product's functional quality.

2. When storing, the environmental conditions required for the product must be met. For stacking two pieces of the product, the boards should be placed facing each other. When stored at construction sites, certain anti-tilt measures should be taken, and they should not be placed leaning against walls.

3. If there is no supporting object during storage, a dedicated stacking rack should be used. The formwork should not be placed directly on other construction materials to prevent tipping over.

4. Construction formwork should not be stored in overly humid environments to avoid cracking or mold due to moisture. Additionally, transport personnel should not throw or drop the materials to prevent damage to the internal or surface quality of the product.

 

1. Inner packing: Inside pallet is wrapped with a 0.20mm plastic bag.
2. Outer packing: Pallets are covered with 2mm package plywood or carton and then steel tapes for strengthening.
3. Delivery Time: 7~20 working days after payment, we will choose best speed and reasonable price.
