PP plastic plywood?

Plastic plywood are composites that are based on advanced technology and semi-high processing experience in the digestion and absorption of European advanced equipment manufacturing technologies and adhere to advanced products and process technology and are extruded at high temperatures of 200°C.

plastic plywood turnover can reach more than 30 times, but also recycling. The temperature adapting range is large and the specification is adaptable. It can be sawed and drilled and it is easy to use. The flatness and smoothness of the surface of the template exceed the technical requirements of the existing fair-faced concrete formwork, and it has the functions of flame-retardant, anti-corrosion, anti-water and anti-chemical corrosion, and has good mechanical properties and electrical insulation properties. Can meet a variety of rectangular, rectangular, L-shaped, U-shaped building mold requirements.

The type of plastic plywood:

Product categories: Plastic steel formwork steel templates, plastic steel square wood, plastic steel yin and yang corners, plastic cylindrical template, steel bridge template and other special-shaped template.

According to the material can be divided into: PVC (polyvinyl chloride), polypropylene (PP), polyethylene (PE), polycarbonate (PC), acrylonitrile-butadiene-styrene (ABS), high-density polyethylene ( HDPE), etc. can be divided according to the appearance of: solid board, hollow board, buckle ribs, module assembly board, plastic square wood, plastic yin and yang.

The advantages and disadvantages of plastic plywood

plastic plywoods are environmentally friendly and energy-efficient. They are economical and economical for recycling, and they have become the new darling of the construction industry.

Plastic plywood eight advantages:

1, smooth and clean. The template splicing is tight and smooth. After demoulding, the surface and smoothness of the concrete structure exceed the technical requirements of the existing clear plywood, eliminating the need for secondary plastering and saving labor and materials.

2, light and easy to install. With light weight and strong process adaptability, it can be sawed, planed, drilled and nailed, and can be composed of any geometric shape at random to meet the needs of architectural forms for various shapes.

3, simple mold release. The concrete does not stick to the board surface and does not require a mold release agent. It is easy to demold and is easy to remove dust.

4, stable weathering. High mechanical strength, under the conditions of -20°C to +60°C, no shrinkage, no bloating, no cracking, no deformation, dimensional stability, alkali-resistant anti-corrosion, fire-retardant and waterproof, and anti-mouse control.

5, conducive to conservation. The template does not absorb water and does not require special care or storage.

6, strong variability. The type, shape and specifications can be customized according to the requirements of the construction project.

7, reduce costs. The number of turnover times is more than 30 for the plane mode and 40 times for the column beam mode. The use cost is low.

8, energy saving and environmental protection. Scraps and waste templates can all be recycled, zero waste emissions

Plastic plywood four major disadvantages:

1. The strength and rigidity of the plastic building template are too small

The flexural strength and the modulus of elasticity of the plastic building formwork are small compared to other templates. The plastic building formwork used in the country is lower in strength and rigidity than the bamboo (wood) formwork and much lower than the external GMT formwork.

2. The carrying capacity of plastic building templates is low

At present, the plastic building formwork is mainly used as the top plate and floor plate formwork with a flat plate type, and the carrying capacity is relatively low. As long as the spacing of the secondary beams is appropriately controlled, the construction requirements can be satisfied. But to be used as a template for a wall column, it must be processed into a steel frame plastic plywood. Therefore, we must also adjust the formulation of plastic building templates, improve production processes, improve the performance of plastic building templates, and also develop GMT templates.

3. the thermal expansion and contraction coefficient of the plastic building template is large

The coefficient of thermal expansion and shrinkage of plastic sheet is larger than that of iron and steel. Therefore, the plastic construction template is greatly affected by the temperature. For example, during the high temperature period in summer, the temperature difference between day and night reaches 40°C. According to the data, at the high temperature, the 3m long sheet can be expanded and contracted. Up to 3mm to 4mm. If the slabs are constructed in the evening, the arching will occur in the middle of the template at noon; if the slabs are constructed in the noon, the template will shrink at night so that there will be a gap of 3 mm to 4 mm between adjacent slabs. To solve the problem of large expansion, the expansion coefficient can be reduced by adjusting the material formulation and improving the processing technology. In addition, during the construction, one can choose an average temperature time to plank, or seal sponge strip between the plate and the plate, which can eliminate the gap of the template, ensure that the poured concrete does not leak the slurry, and can solve the problem of arching at high temperature.

4. welding slag easy to burn bad plastic construction template

At present, plastic plywood are mainly used as floor slab plywood. When steel bars are laid, welding slags produced by welding are very hot and fall on plastic plywood when they are connected with steel bars, which can easily scorch the plates and affect the surface quality of molded concrete. Therefore, flame retardants can be properly added to polypropylene to improve the flame retardancy of the plastic plywood. In addition, protective measures can be taken during the welding operation. For example, a piece of stone cloth can be sent to the welder. The flat template can be tiled under the solder joint. For the erection template, a small piece of wood can be leaned against the solder joint to solve the problem of electric welding. Bad plastic construction template problem.
