The application of wood-plastic building formwork

Wood-plastic building formwork is a new type of formwork that replaces steel formwork and bamboo-wood plywood. It has many advantages such as light weight, high impact resistance, easy assembly, high turnover rate, smooth surface, non-hygroscopic, non-moldy, acid and alkali resistant, no cracking, large panel size, few seams, sawable, nailable and processable into any length. It can be recycled repeatedly, and its price is much lower than that of the bamboo and wood formwork currently used in the construction industry. Moreover, it has excellent flame-retardant performance, self-extinguishing when removed from the fire source, smokeless and free of any toxic gases. It is a new generation of safe, green, environmentally friendly and energy-saving products.

According to relevant regulations, the main indicators of standard formwork should be capable of withstanding loads, mechanical strength and other indicators.

In line with the national standard GB/T15496, GB/T15497, GB/T15498 and GB/T19273. According to the relevant national standardization documents, the total score for the evaluation and acceptance is 500 points. A score of 420 points or above can obtain the AAA-level confirmation of good standardization behavior.

Energy-saving advantages of wood-plastic formwork products

Wood-plastic panels can replace wood and protect forest resources.

2. Wood-plastic panels can utilize plant straw, reducing environmental pollution.

3. Wood-plastic panels can eliminate white pollution and beautify the environment.

Main raw materials Wood-plastic Composites (WPC), also known as wood-plastic composites, is a new type of composite material that has flourished at home and abroad in recent years. It refers to a new material formed by mixing polyethylene, polypropylene, polyvinyl chloride, etc. instead of the common resin adhesives with a certain amount of waste plant fibers such as Wood powder, rice husks, and straw. Then, through extrusion molding, the produced plates or lines. It is mainly used in the building materials, home decoration and other industries. The board formed by hot extrusion after mixing plastic and wood powder in a certain proportion is called wood-plastic composite board.

Application fields: building formwork, door panels, interior and exterior decoration of houses, home decoration materials, outdoor decorative boards, plastic interior doors, flooring, skirting boards, overall kitchen cabinets, wardrobes, decorative hanging boards, outdoor flooring, etc.

The ten advantages of the material

Waterproof and moisture-proof. It has fundamentally solved the problem that wooden products are prone to rot, expand and deform after absorbing water and getting damp in damp and water-rich environments, and can be used in environments where traditional wooden products cannot be applied.

(2) Insect and termite prevention, effectively eliminating insect disturbance and extending service life.

(3) Rich and diverse, with a wide range of colors to choose from. It not only has the natural wood feel and wood grain, but also can be customized in the desired color according to one's own personality

(4) It has strong plasticity and can be very easily shaped into personalized forms, fully reflecting individual style.

(5) High environmental friendliness, no pollution, no harm, and recyclable. The product contains no benzene substances and has a formaldehyde content of 0.2, which is lower than the EO grade standard. It meets the European environmental protection classification standard and can be recycled, greatly reducing the use of wood. It is suitable for sustainable development countries and benefits society.

(6) High fire resistance. It can effectively resist fire, with a fire resistance rating of B1 grade. It self-extinguishes when removed from the fire source and does not produce any toxic gases.

(7) It has good processability, can be nailed, planed, sawn, drilled, and its surface can be painted, transferred or laminated.

(8) It is easy to install and convenient to construct, without the need for complicated construction techniques, thus saving installation time and costs.

(9) It does not crack, expand or deform, requires no maintenance or upkeep, is easy to clean and saves on later maintenance and upkeep costs.

(10) It has excellent sound absorption effect and energy-saving performance, enabling indoor energy savings of over 30%.

The production process of wood-plastic formwork: Mix raw materials → Feed into the automatic feeding machine → melt and plasticize in the extruder → Mold → extrusion molding → board forming mold → calendering → cooling → traction machine → longitudinal cutting → transverse cutting → stacking rack → inspection → qualified products are stored in the warehouse → defective products are recycled and ground into powder

Configuration of wood-plastic formwork equipment

1. Wood powder grinding machine - mainly used for grinding wood powder, bamboo powder, straw, etc

2. Mixer - mainly used for the mixing of chemical auxiliaries such as wood powder, plastic, and fillers

3. Extruder - mainly used for extrusion molding of template products (molds are ordered according to the width of the product)

4. Crusher - mainly used for the recycling and crushing of waste products

5. PVC grinding mill - mainly used for grinding recycled defective products
