Why does plywood appear to be discolored and moldy

图片
  In order to prevent discoloration and mildew on the surface of the  film faced plywood , pay more attention to moisture-proof during use. 1 It is necessary to prevent the room from being too humid, to prevent water and rain. 2 The film faced plywood should be nailed during the construction and decoration to prevent damp and mildew. 3 After the decoration, the film faced plywood should be prevented from drying and cracking. 4 Drying when cleaning to prevent the rag from being too wet and making the product moldy. 5 Prevents the film faced plywood from melting, staining, volatilization, squeezing, loss, leakage, and theft , Collision, can come to protect the goods from wind, rain, sun and dust.   ZMADTO Plywood Co.Ltd  is focus on construction plywood & wood formwork product.

Quality Requirements of Plywood

  Film faced plywood   is widely used in the construction industry nowadays. As the engineering projects used are generally relatively large, there are certain requirements for the appearance of film faced plywood.  1. Color: high-quality building templates should have natural colors, clear wood grain, and the raw materials are visible to the naked eye. If the plywood has a dark appearance, the thicker paint layer may be intentional to cover up the defects of the plywood, especially when the plywood is six-sided sealing paint.  2. Grain: It is the standard for judging the quality of film faced plywood. The regular pattern is beautiful and generous. Do not choose the plywood with disorderly patterns.  3. Knots: Knots, which can be divided into live knots and dead knots. As a natural product, it is impossible to have no knots. The reasonable distribution of live knots will make wood products more beautiful. Premium products are not allowed to have defective knots.  4. Cracks: It is inevi

Reasons for Deformation of Film Faced Plywood

  1. Assemble small steel molds, which are not set up according to regulations, resulting in poor overall performance of the building 2. The foundation on which the template is placed is not firm, the  film faced plywood  is not placed, and the foundation is sinking due to poor waterproof measures. 3. Use wooden building formwork or film faced plywood for construction, and the concrete is not poured in time after the experience is accepted, and the surface is deformed in the sun and rain for a long time. 4. The support spacing is too large, and the rigidity of the film faced plywood is poor 5. The speed of pouring wall and column concrete is too fast, the height of one-time pouring is too high, and the vibration is excessive.   ZMADTO Plywood Co.Ltd  is focus on construction plywood & wood formwork product.

Material Requirements for Wooden Formwork

  The   wooden formwork  is composed of a panel and a support system. The panel is the part that makes the concrete shape; the support system is the structural part that stabilizes the position of the panel and bears the upper load.   The quality of the formwork is related to the quality of the concrete project. The key is accurate size, firm assembly, tight joints, and convenient assembly and disassembly. The appropriate form of template should be selected according to the form and characteristics of the structure to achieve good technical and economic effects. The formwork and support system of large and special projects shall be calculated to check the stiffness, strength, stability and ability of withstanding lateral pressure.   1. The base formwork is made of pine wood, poplar wood, and eucalyptus wood. The thickness of the side slab of the ground beam is 20mm.   2. The bottom template of the main beam is made of pine wood, and the thickness of the bottom template is 40mm. The col
