PC board processing PC board how to bond strength will be better
So it is not a so-called neutral sealant. Because the sealant has no strength, the viscosity cannot accept mechanical force. Understand that bonding is not sealing. The main thing depends on the size of your bonding area and bonding shape, which can be selected according to the situation, but the best effect is definitely UV glue. After bonding, it is transparent and has no traces, waterproof, environmentally friendly, and high temperature resistant. This glue cures quickly under ultraviolet light. If you consider the interest, you can also use AB glue, according to your requirements for the curing time of the glue to determine which is more appropriate, but this kind of glue has an extra step of adjusting the glue.
If the bonding area of u200bu200bthe PC board is small, quick-drying glue is a good choice.
The bonding strength of these three types of glues is very good, it does not need to be treated with a treatment agent before bonding
PC board is made of polycarbonate material, which is afraid of acid Alkali, so it is generally necessary to pay attention to the use of neutral glue. If the partial acid-base glue is used, the PC sheets will be corroded quickly, the PC sheets will become hard and brittle, and it is easy to be damaged.
There is another problem that should be paid attention to. Before bonding, the bonding part of the PC board must be processed to ensure light weight: the specific gravity is only half of the general glass, and it is not easy to break, and the handling device is less. It saves time and effort, especially suitable for tall buildings.
2 Light transmittance: The colorless transparent solar panel can provide excellent transparency and surface gloss. The colored panel can block the strongest part of the sunlight and make the transmitted light soft. The light transmittance is as high as 92%
3 Sound insulation performance: PC sheets can effectively reduce noise, and it is the first choice for highway noise barriers in the world.
4 Heat transfer: It has a thermal conductivity (K value) lower than that of ordinary glass and other plastics, which greatly reduces heat loss. It is used in buildings with heating equipment and is an environmentally friendly material.
5 Impact resistance: the best impact resistance among pc sheet thermoplastics. The sun board made of pc sheet can maintain good impact resistance for a long time in a wide temperature range. Performance, has the reputation of 'not broken glass' and 'sounding steel'.
6 Anti-condensation: Under normal circumstances, when the outdoor temperature is 0°C and the indoor temperature is 23°C, as long as the indoor humidity is lower than 80%, there will be no condensation.
custom polycarbonate sheet has become a standardized way of dealing with custom plastic sheets.
should only be created by the very best custom polycarbonate sheet companies with the training, experience and know how about what is expected of them.
We attach a great importance to domestic market and knows the importance factors of manufacturing custom polycarbonate sheet, such as producing methods, etc.
custom polycarbonate sheet continued to evolve to having strong manufacturers develop huge marketers and people came to value their opinions about what to buy.
We take advantage of high technology to produce products that support safer and better quality and that enhance the using experience of custom polycarbonate sheet.
