Factory, commercial buildings, multi-storey residential areas and renovation of old buildings, etc.
Second, the use of large scale
The pvc exterior wall hanging board is a special composite material composed of high-efficiency and long-term anti-ultraviolet anti-disorder agent, which is resistant to cold and heat, durable, anti-ultraviolet and anti-aging. It is especially good in corrosion resistance in alkali, salt and humid areas, can resist various harsh climates, can last as new under the influence of various natural weathering, is easy to clean (can be washed), and is free of protection (no paint and coating required). ).
3. Good fire performance
The oxygen index of pvc exterior wall siding is 40, flame retardant and self-extinguishing away from fire, conforming to the fire protection standard B-level (gb-t 8627⑼9).
4. High energy saving
The inner layer of the pvc exterior wall hanging board can be extremely convenient to install polyethylene foam material, so that the external wall insulation effect is better.
Polyethylene foam material is like putting a layer of “padded coat” on the house, and the outer wall hanging board is a “coat”, the house is warm in winter and cool in summer, and the energy saving is very good.
5. Convenient installation
The pvc exterior wall hanging board has an advanced structure, is easy to install and is firm and reliable. A villa of 200 square meters can be installed in one day. The exterior wall siding project is by far the most labor-saving and time-saving exterior wall decoration solution.

6. Long service life
1. Generally, the service life of the product is at least two or five years, and the service life of the double-layer co-extrusion product with the surface of the product asa of the American ge (General Electric) company is more than 30 years.
Seven, good environmental protection
The pvc exterior wall siding does not pollute the environment in the production process or in the engineering practice, and can be recycled. It is an ideal environmental protection decoration material.
8. High comprehensive benefit
The installation process of pvc exterior wall hanging board is simple and fast, all dry work, firm and reliable, which can greatly shorten the construction period.
Construction technology of pvc exterior wall hanging board
1. First, measure the verticality of the outer corner of the floor and the horizontality of the horizontal start. If the error is too large, you should negotiate with Party A for remedial measures, and the construction can only be carried out after Party A approves;
2. According to the installation procedure of the hanging board, first install the accessories (outer corner post, inner corner post, starting strip, J-shaped strip), and then install the hanging board. There should be at least six expansions between the hanging board and the corner of the strip (horizontal direction). space;
3. Because the wall has a thermal insulation layer, plastic expansion bolts and screws are used to fix the hanging board. The total length of the expansion bolts is: the thickness of the thermal insulation layer + the thickness of the cement mortar + 35, the deep wall is not less than 30, and the diameter of the steel screw is Fourth, the diameter of the head shall not be less than eight. Fix 1 expansion bolt every 601750px, and fix 1 steel screw every 30-1000px. The exterior wall siding itself belongs to a kind of light body decoration material. The weight of each square meter of siding is about 2 kilograms. At least six expansion bolts and eight screws should be driven into one square meter. On average, each expansion bolt (screw) The load-bearing capacity is about 0.16 kilograms. Previously, we conducted sampling experiments on the thermal insulation bricks in the walls of similar projects. The expansion bolts and screws are strong and firm enough to withstand the gravity from the hanging board itself and a certain degree of external force (such as wind) ;
4. The steel nail should be nailed at the center of the nail hole. It is not allowed to nail on the board surface without nail hole to prevent the board surface from protruding and deformed due to the expansion and contraction space. There should be a gap between the nail head and the hanging board. The nails are too tight;
When the two hanging boards are installed together, the overlap amount is 25⑸0, and the flange of one hanging board should be cut off to make the lap joint more flat.
