When choosing to buy a membrane metal composite board, you should pay attention to what problems, first of all, you must know the use and environmental corrosion of the selected film -covered metal composite board. Then choose the appropriate coating metal composite plate according to the needs, just like ordinary environmental chickens use ordinary membrane metal composite boards. This is the choice of material. In addition, the following is an important factor when choosing a membrane metal composite board.
Selection of previous colored films
1. Color film
The thin film of different colors has different hardness, flexibility, adhesion and durability. The PVC color film is currently the most widely used color film. It is generally durable, good hardness and toughness, and moderate prices.
The color film is mainly affected by the corrosiveness, service life, durability, processing method and deformation degree of use of the environment.
2, primer
There are certain differences in the adhesion, toughness and corrosion resistance of different primer paint. The epoxy resin and substrate adhesion is good, and the corrosion resistance is high, but the toughness is not as good as other primer. Polyester has good adhesion to the substrate and excellent toughness, but corrosion resistance is not as good as epoxy resin. Polyurethane is a kind of primer with good comprehensive performance. The primer is usually corroded by the supplier according to the production process, use, and the environment of the environment. Select the matching relationship with the noodle paint.
3. Color film color difference
Color film will be colored in production and use. Due to the influence of various factors such as production organizations, depth, service time, service environment, and use of production organizations, color differences are usually negotiated with suppliers and demand.
4. Color film gloss
Mainly selected based on usage and usage habits. Generally, the building plate is low -gloss, and the home appliance board is first selected.
5. The toughness/adhesion of the color film
This performance is closely related to the processability of the metastic metal composite board, which is mainly selected according to the processing method and deformation degree. When the deformation speed is fast and the degree of deformation is large, choose a coated metal composite with high impact energy and small T -type bending values. plate.
6, durability
Durability is the use of performance. It is usually measured by the service life. It is closely related to the type, thickness, and corrosiveness of the use environment.
7. Other performances
Environmental protection requirements have good solvents, acid and alkali, pollution resistance and heat resistance, so they must pay enough attention to these requirements.
