This article mainly introduces the differences between PVC plastic gussets and aluminum alloy gussets and their respective advantages:
PVC plastic gusset plate is made of PVC, light weight, easy to install, waterproof, anti-mite, surface color pattern change is also very much, and it is resistant to pollution, good cleaning, good performance of sound insulation and heat insulation, especially in new technology. Add flame retardant material to make it safe to use. The downside is that the service life is relatively short compared to metal ceiling panels.
When purchasing PVC ceiling profiles, in addition to requesting the quality inspection report and product inspection certificate from the dealer, the appearance quality can be visually observed. The surface of the board should be smooth and smooth, free from cracks, bumps, and can be disassembled and freely. Scratch, tapping the surface with your hand is crisp.
The plastic gusset ceiling consists of a 40mm×40mm square board, and a plastic gusset is placed under the skeleton. This type of ceiling is more suitable for decorating the bathroom ceiling.
If the PVC ceiling profile is damaged and updated, it is very convenient. As long as a real strip is removed, the plate is taken out from the bead block by block, the damaged plate is replaced with a new plate, and the bead is re-installed. Care should be taken to minimize chromatic aberration when replacing.
Compared with traditional ceiling materials, aluminum alloy gussets are superior in texture and decoration. The aluminum alloy gusset plate is divided into two types: a sound absorbing plate and a decorative plate. The sound absorbing plate has a round hole, a square hole, a long circular hole, a rectangular hole, a triangular hole, a combined size hole, etc., and the bottom plate is mostly white or aluminum; Special attention is paid to the decoration, the lines are simple and smooth, and there are colors such as bronze, gold, red, blue, milk white and so on. There are rectangles, squares, etc. The maximum size of the rectangular plate is 600mm×300mm, and the width of the general room is about 5m. The decoration of the larger room is stronger than the long strip. The decoration of the small room is generally 500mm× 500mm, due to the poor thermal performance of the metal plate, in order to obtain a certain sound absorption and heat function, when selecting the metal plate for ceiling decoration, it can use the method of adding heat-absorbing and sound-absorbing materials such as glass wool and rock wool to achieve the heat. Sound absorption effect.
The PVC plastic gusset plate has strong water and scrub resistance, and the cost is relatively low. The aluminum alloy gusset has better texture and decorative feeling.
Cylindrical Lens is used to correct astigmatism in the eye, and, in rangefinders, to produce astigmatism, stretching a point of light into a line.They are available in either Plano-Concave Cylinder Lens or plano-convex cylinderical lens configurations. Plano-Concave Cylindrical lens has a negative focal length and are used for image reduction or to spread light. Plano-Convex Cylinder lens has a positive focal length, which makes the cylindrical lens ideal for collecting and focusing light for many imaging applications. Every sizes,materials cylindrical lens are available according to your detailed parameters.
Some styles of cylindrical lens have antireflective coatings to increase the transmission of light through the cylindrical lens.
Fused silica cylindrical lens is ideal for demanding laser machining and medical applications.
