Which is better for thermal insulation of coated glass or pc board?

1. Coated glass and PC boards both have certain heat insulation effects, but each has different characteristics and application scenarios. The thermal insulation performance of coated glass mainly comes from the thin film layers on the surface of the glass, which can reflect part of the heat, thereby reducing heat transfer. Coated glass can effectively block ultraviolet rays, reduce indoor heat absorption, and provide better heat insulation. It is suitable for buildings that need to keep the indoor environment cool, such as office buildings, residences, etc.

2. Polycarbonate PC endurance board: The surface has a thermal insulation UV coating, which can effectively block heat transfer and has a good thermal insulation effect.

3. It is often used in building windows, doors and windows and other places that need insulation. PC boards are more used in outdoor awnings, canopies and other occasions because of their strong impact resistance and good light transmission. Although insulation is also considered in these occasions, more attention is paid to their safety protection and light transmission performance. To sum up, glass performs better than PC boards in terms of insulation. If you need to consider the insulation effect, glass is a more suitable choice.

4. It is recommended to use Low-E coating to improve thermal insulation. The price of a single layer is about 150-300 yuan/㎡. Polycarbonate board (PC board) is light in weight, impact-resistant (200 times that of glass), has a light transmission rate of 80%-90%, and the double-layer hollow structure has significant thermal insulation effect. The price is 120-400 yuan/㎡, and the service life is 10-15 years. Laminated glass Two pieces of glass are sandwiched between PVB film, which is explosion-proof and UV resistant and has good sound insulation effect.

Introduction of antistatic PC board

1. Anti-static PC boards are widely used in the construction of clean room plants (semiconductors, LCD, electronics, optics and medicine, etc.), shielding of clean room equipment, separation of clean room spaces, cleaning equipment, observation windows and equipment covers, electronic testing fixture, etc. The substrate is polycarbonate, abbreviated as PC, which is a colorless and transparent amorphous thermoplastic material.

2. Anti-static PC board: It has the characteristics of high strength, high light transmittance, good impact resistance and weather resistance, and also has good antistatic properties. It is often used in occasions where high transparency and antistatic protection are needed. Anti-static PET board: It has excellent mechanical properties, electrical properties and processing properties, as well as good antistatic effect, and is widely used in electronics, communications, medical and other fields.

3. Anti-static materials include antistatic plexiglass plates, antistatic PVC plates, antistatic PC plates, antistatic PET plates, antistatic nylon plates, etc. The specific introduction is as follows: Anti-static plexiglass board: This is a transparent material with antistatic function and is widely used in occasions where electrostatic interference is needed.

4. Anti-static materials mainly include antistatic plexiglass plates, antistatic PVC plates, antistatic PC plates, antistatic PET plates and antistatic nylon plates. Anti-static plexiglass board: This is a transparent board with antistatic function. It is widely used in electronics, communications, medical and other fields. It can effectively prevent static interference and damage to equipment.

How much ultraviolet light can the pc board block?

1. Anti-ultraviolet coating: A UV coating will be added to the surface of high-quality PC endurance boards, which can block more than 99% of the ultraviolet light and prevent the molecular chain of the board from breaking, yellowing and becoming brittle due to ultraviolet radiation. It is the key to extending outdoor life. Use environment: Under outdoor high temperature, high humidity, and strong ultraviolet rays (such as tropical areas), the aging rate of the plates will accelerate; while in indoor or sheltered environments, the life can be extended to more than 20 years.

2. The surface of high-quality PC endurance board has a UV coating, which can block more than 99% of ultraviolet light and avoid problems caused by ultraviolet radiation. This is the key to extending outdoor life. 3) In outdoor high temperature, high humidity, and strong ultraviolet environments, the plates age quickly; indoors or sheltered environments, they can be used for more than 20 years.

3. Although the two are similar in terms of light transmission, the PC endurance board is co-extruded with an anti-ultraviolet layer on the surface of the board, which can isolate more than 99% of the ultraviolet light, while the 3mm thick glass has a wavelength of 350 nm. Ultraviolet light can transmit 80%. This characteristic not only extends the life of the plate, but also allows indoor personnel to avoid worrying about ultraviolet damage to the skin. Thermal insulation performance: The heat transfer coefficient of traditional single-layer glass is between 6-6 W/m2℃.

4. This strong impact resistance allows the PC endurance board to withstand extreme weather conditions such as hail and typhoons. Even if it is subjected to strong impact, the board will not break, but will produce cracks, thus greatly reducing safety hazards. This feature is particularly suitable for sunrooms in high-rise or coastal areas, ensuring safe use in severe weather.

What is the difference between pc board and pvc board?

1. The difference between PC and PVC board is mainly reflected in the following aspects: Material nature: PC board: PC material is polycarbonate material, which is a colorless and transparent amorphous thermoplastic material. PVC board: PVC board is a polyvinyl chloride material. It is currently the second largest general plastic in output. It is also a widely used plastic. PVC itself is also a colorless and transparent hard material.

2. Different materials: PC boards, namely polycarbonate boards, including PC sunshine boards, PC endurance boards and other types, are made of polycarbonate, a thermoplastic. PVC board is a board made of polyvinyl chloride (PVC). Its cross-section is usually a honeycomb mesh structure and belongs to a type of vacuum blister film.

3. The main difference between PC board and PVC board is the substrate. The substrate of PC board is polycarbonate, and the PVC board is polyvinyl chloride. This difference leads to their different characteristics. The density of PC board is lower than that of PVC board, the continuous use temperature is higher than that of PVC board, and the light transmission performance is better than that of PVC board. They have similar visible light transmittance and both can completely block ultraviolet light.

4. Aging resistance: PVC boards are not resistant to aging and generally cannot be used in outdoor environments; PC boards can be used in outdoor environments and have good sound insulation. Electrical properties: PC board is an excellent insulator material;PVC board is used as a low-frequency insulating material, with better electrical properties but not as good as PC board. Corrosion resistance: Both have strong corrosion resistance, but the corrosion resistance objects are different.

5. During the construction process, PC plates are relatively easy to install due to their strong rigidity and large coefficient of thermal expansion and contraction. However, pvc must not be used in outdoor lighting because it is not resistant to old fire and easy to burn.

How to polish pc transparent plates

1. Mechanical polishing: Use grinding and polishing tools to treat the surface of PC materials. Tiny defects and non-uniformities can be removed, making the surface smoother and improving transparency. Chemical polishing: Soak the PC material in a chemical liquid and process it under specific temperature, time and pH conditions. The chemical reaction dissolves the thin film on the surface layer, achieving surface planarizing and improving transparency. Vacuum coating technology: By applying vacuum to the PC board, a very thin and uniform coating layer is formed on its surface using physical or chemical methods.

2. The main methods for polishing PC boards include (1) polishing with general wool pads;(2) polishing with polishing knives or utility knives;(3) laser flame polishing, etc. PC board polishing: PC board polishing is mainly the post-processing of the cut or engraved cross-section of the PC board. Each polishing process has its own advantages, and different polishing processes can be selected according to needs.

3. For scratches on transparent engineering plastic plates (such as acrylic and PC endurance plates) commonly known as plastic glass, the depth of the scratches must be judged first, and then the corresponding repair plan must be selected: light scratches must be removed by polishing and filling, and deep scratches must be polished first. Fill in and finish.

4. The most effective way to remove yellow stains on transparent plastic plates is to use hydrogen peroxide (hydrogen peroxide) with ultraviolet radiation, or use professional plastic polishing agent.

5. The core method for yellowing transparent plastic plates to restore primary colors: use chemical solvent bleaching or physical polishing. The specific choice depends on the plastic material and the degree of yellowing.
