PC light cover

Polycarbonate PC daylighting cover has very high transmittance and refraction performance, which can effectively penetrate natural light into the system. On the one hand, the design of arc and hem can refract low angle light into the system, making the daylighting area far larger than the area of the daylighting cover. On the other hand, dust in the air is not easy to adhere to avoid frequent cleaning and maintenance. Special materials and processes can isolate most ultraviolet rays, and make them have very good weather resistance and impact resistance.

With the development of science and technology, architects have higher and higher requirements on the design effect, and they often require strange shapes for the shape of the lighting cover. Therefore, poly Bayer can make various special-shaped lighting covers according to your needs.

 

Common special-shaped PC light shield:

1. The bottom frame is a trapezoidal arch with a circular arch on the top;

2. The bottom frame is polygonal and arched;

3. The bottom frame is a triangle with a circular arch on the top;

4. The bottom frame is triangular, and the upper cover is conical arched;

5. The bottom frame is polygonal and arched;

6. The bottom frame is polygonal, with irregular arch on the top.

 

PC lighting cover body is upper and lower cover body, double-layer structure lower cover body is generally 3 mm, the original machine glass 3 mm or 4.5 mm polycarbonate plate (commonly known as bulletproof glass) is made into spherical upper cover. According to the customer's needs, 4 mm PC endurance plate can be used to make spherical or pyramid cover, and the lower opening can be made into square, rectangular, triangle or trapezoid.


 



Round arch type light cover:

1. The light shield is arched with rectangular bottom frame and circular arch;

2. The light shield is arched up with square bottom frame;

3. The light shield is arched with trapezoidal bottom frame;

4. Circular arch daylighting cover with irregular polygonal bottom frame








Diamond type light collecting cover: also known as conical light collecting cover, it is a common shape of lighting cover.

The diamond type lighting cover can be divided into:
1. The bottom frame is square and the upper cover is conical arched;

The upper surface is triangular and the bottom is triangular;

3. The bottom frame is polygonal, and the upper cover is multi face conical arch.

The electric opening type daylighting cover is a new type of building decoration, which is mainly used for the roof and ceiling of daylighting, which adds new content to the roof and ceiling construction.
With the progress of society and the development of construction industry, more and more modern buildings need large area of daylighting. People's eyes naturally focus on the inexhaustible and cost-free sunlight. However, the lighting materials (such as glass) can not meet the requirements of waterproof, windproof, impact resistance and light weight. In order to meet the needs of the society, the high-grade light cover with good lighting, impact strength, waterproof and wind erosion resistance is produced by using new materials.


In case of ventilation and smoke exhaust requirements, but there is no forced ventilation measures on the roof, it can be considered to open the light shield. There are two opening modes: semi-automatic and full-automatic.

1. The daylighting cover is made of imported high-quality polycarbonate PC material added with UV injection molding or hot molding. The material itself has strong abrasion resistance and impact resistance, with transmittance of 87% and isolation of more than 90% UV. At the same time, due to the addition of UV material, the yellowing index of the light cover is greatly improved, and the yellowing performance is less than 1.

2. The spherical surface design, in addition to beautiful appearance, its biggest function is to make it receive light in a larger area and prevent the accumulation of large particles of dust.

3. Light bending technology, optical design at the bottom of PC daylighting cover, which can effectively increase the collection of natural light in the morning and evening and daily.

Installation of PC lighting cover:
1. Place a waterproof rubber pad on the outer side of the EPDM.
2. Place the low layer (or single layer) lighting cover on the rubber pad, align it with the bottom frame, and place it in the middle.
3. The elastic single-sided rubber pad (double-layer lighting cover) is pasted on the four sides of the low-rise lighting cover.
4. Put the upper lighting cover on the first layer and align it. (single layer lighting cover omitted 3.4)
5. Apply a full circle of neutral glass glue on the upper pressure frame of the daylighting cover, press the upper pressure frame on the double or single-layer lighting cover and align with the bottom frame.
6. In the upper corner of the upper corner of the upper corner of the upper pressure frame, first drive four self tapping screws. In order to prevent displacement, two people hold the screws diagonally during nailing. Align the self tapping screws along the four corners with a distance of 30cm-40cm. (Note: the self tapping screw shall not hit the lighting cover)
7. At the side of the upper pressure frame, the self tapping screws were driven at a distance of 30-40cm.
8. After the cover body is fixed, paste the edge of the lighting cover 3-5mm higher than the upper pressure frame to prevent the uneven edge from damaging the cover body.
9. Pour neutral structural adhesive (no breakpoint) into the gap between the upper pressure frame and the cover body, and smooth the glue to form a slow slope filling between the lighting cover and the upper pressure frame.
10. Remove the masking paper and install the lighting cover.


1、 Cleaning of PC lighting cover:

According to the correct steps, clean the plate regularly with suitable cleaning solvent and tools, which can make the plate beautiful and prolong its service life
1. Rinse with water (below 60 ℃).
2 clean soft cloth or sponge dipped in neutral soap or detergent to gently clean the dust and dirt on the board surface. It is strictly prohibited to use coarse fiber fabric or brush to contact the board surface. It is absolutely not allowed to use scraper, razor or other sharp tools to scrape and grind.
3 rinse with water again.
4. If there are grease, wet paint and glue mark on the board surface, it can be wiped off with a soft cloth dipped in anhydrous alcohol, kerosene or gasoline.
5 after cleaning, rinse with cold water, and then dry the plate with soft cloth to prevent water spots.


2、 Maintenance of PC lighting cover:
Under normal use, only water treatment is required, do not clean with organic volatile solvents, such as toluene ~ banana water ~ etc. Also can not use the market volatile cleaning agent. Such as magic spirit cleaner, if used, its consequences are only one. Short is a day, long is a week. The PC will be fragmented. It is also not recommended to use hard objects to remove large areas, because it will damage the surface smoothness of PC board
