PP plastic formwork for concrete slab
PP hollow precast concrete mold wall panel formwork is new kind of constrution concrete formwork. It is used high quality recycled polypropylene particles. It is suitable to realize concrete columns, pillars, walls, plinths, and foundations directly onsite. This formwork is according to the principle of structural mechanics, neatly arranged, increased four times support, stronger and more robust, on both sides of the formwork are right angle processing, increasing the bear capacity, construction is more convenient, its hollow structure makes the product expansion coefficient small and light easy to move. Now PP hollow structure formwork is becoming more and more popular.
♦Advantages:
1. Light weight, high strength, high hardness, impact resistance, wear resistance.
2. Surface is smooth, bright and clean; concreting and forming effect is good.
3. No absorption of moisture, no deformation, no mildew; Long-term immersion stratification in the water, no bubbles, sheet size stability, especially suitable for underground and damp environment.
4. Good toughness. It could be used as cambered special-shaped formwork.
5. Acid and alkali resistance, corrosion resistance; Very suitable for the engineeringapplication in
coastal areas, mine, as well as seawall. It is need not do any preservative treatment both in using and storing the formwork, which do not pollute the concrete surface.
6. The reusable time can reach more than 60 times, long service life.
7. Waste products can be recycled and reprocessed, making full use of waste materials. This property can greatly reduce the project cost compared with wooden formwork and bamboo formwork.
8. Environmental protection and energy saving, no pollution. No any poisonous or harmful gas.
9. Demould easily. No need brushing release agent, only tapping, the formwork will fall off. Shorten working hours and speed up the construction schedule efficiently.
10. Easy to process. Sawing, drilling and nailing are all available. Formworks can be combined vertically and horizontally optionally.
11. Easy to remove. Removing is convenient, quick and safe, and the supporting is also easy to operate, advantageous to the organization construction, effectively improving the construction schedule.
♦ Market Study:
Plywood formwork is the most common and economic choice for constriction formwork. But with the times going on and the environmental requirements getting higher and more strictly, its short comings also getting more obviously. So plastic formwork became ist best substitute. Like PVC formwork and PP hollow formwork.
PP hollow construction building formwork with its light weight, waterproof and more reusable times advantages, make it more and more popular in formwork market.
The shortage of plwood formwork lead to import timber price rising and make it cost higher. Besides, the wooden formwork is not recycled which causes a large waste and operating cost of construction. Plastic formwork is a kind of energy-saving and environmental protection products. Replace of traditional pine plywood formwork already happend.
