Plates are our most common home improvement materials. There are also many uses for plates. Therefore, we must choose a trustworthy brand when selecting plate materials. Do you know what to pay attention to when purchasing plates? We will introduce you to the Lushui River plate and what precautions to take when buying it. Lushuihe plate please 1. The influence of the Lushuihe plate in China is still very great. The production enterprises in Jilin and Lushuihe are mainly composed of pine wood. The stability of the pine is strong, and the plate is relatively good in all aspects because the pine In itself, it is a raw material with its own aroma, so the finished furniture is accompanied by the fragrance of pine wood. The Lushui River plate has three sizes of different sizes, which are 48 feet, 68 feet and 79 feet. Completed the E1 level of standards, is a 10-ring certified product. 2. Lushuihe plate is flat in appearance, uniform in color on the surface of the board, strong and scented with pine wood, and is not irritating to air. The range of formaldehyde release is between 5 mg and 100 grams. What to consider when buying 1. When purchasing Lushuihe plate, it is necessary to look for whether there is a production mark of Jilin Forest Industry Co., Ltd. The Lushuihe plate mainly produces particle board, high-density board, solid wood board and so on. The surface of the particle board is waterproof. Whether the board is fireproof depends on whether the fire resistance of the surface of the board reaches a certain level. However, it is difficult for the bamboo to have fireproof performance. 2. Observe whether the surface of the plate is smooth and whether the color is uneven. Pay attention to whether the side of the plate is neat, and the evenness of the shavings. 3. Check the manufacturer's certificate of conformity. All Lushui River 's products are in line with European environmental quality standards. The formaldehyde released from melamine ply E1 grade is between 9 and 100 grams. 4. When choosing the Lushuihe plate, the merchant is required to present the sales order form, as well as relevant materials such as the authorization form, so as to prevent some unscrupulous merchants from claiming to be Lushuihe brand. It usually contains a large amount of power of attorney and is relatively stable. Otherwise, the Lushuihe sales department will not sell it. 5. When you are skeptical about the selected Lushuihe furniture, you can ask the merchant to show the specifications of the furniture, such as the cabinet, to show the cabinet, the cabinet door, and the backboard to prove that the purchased furniture is authentic. Xiaobian Summary: The above is what are the considerations when Lushuihe plate Xiaobian to introduce the right and the purchase, in order to avoid buying defective products before purchase, have to understand, look at every detail of the plate, hope The above introduction can help you, if you need more information, please continue to pay attention to this site.
PEI plastics (polyetherimide plastics) is an amber transparent solid. It has an inherent flame retardancy and low smoke concentration without adding any additives. The oxygen index is 47%, and the combustion level is ul94-v-0, and the density is 1.28~1.42 g/cm3.
PEI plastics has a strong thermal stability, and even the non-enhanced PEI plastics still has good toughness and strength.Therefore, the high thermal stability of PEI plasticsis used to make high temperature heat-resistant devices.
PEI plastics has excellent mechanical properties, electrical insulation performance, radiation resistance, high temperature resistance and abrasion resistance, and can be used by microwave.The PEI plastics also has good flame retardancy, chemical resistance and electrical insulation.Vitrification transformation temperature is very high, up to 215 ℃.PEI plastics also has a very low shrinkage rate and good mechanical properties.Adding fiberglass, carbon fiber or other fillings to enhance the purpose of modification;And other engineering plastics of heat-resistant polymer alloys, can be in 160 ~ 180 ℃ under the working temperature of use for a long time.
The long-term use of polyether amines in the us underwriters laboratory is 338T and 356T (according to the grade), and the combustion rating reaches UL94V - 0 (10 mille thickness).The oxygen index is 47, and the polyetherimide is in line with the requirements of the aircraft for the requirements of the FAA's flame retardant and thermal release material standards.It has a glass transition temperature of 419F and is allowed to be used intermittently under 392F, at higher temperatures, resulting in a short-term shift.Under 356T, the tensile temperature and flexural modulus were above 41 and 2068MPa respectively.The material reinforced with Glass Fiber and carbon fiber has higher strength and rigidity under the transition temperature of glass.
PEI plastics long-term resistance to creep under high temperature and stress allows it to replace metals and other materials in many structural devices.PEI plastics shows good performance in variable temperature, humidity and frequency.The low dissipation factor at GHz frequency makes the polyetherimide have high microwave wearability.Its ionic pollutant is low, at 250F100 % R.H.And 207kPa after 120 hours of water extraction with the conductivity, at 20 megaohm, it can be used as an electronic sensor element insulation.
PEI plastics is a fine coating and film forming material which can be used for the coating and film of electronic industry, and can be used in manufacturing aperture < 0.1 mu m, with high permeability microporous diaphragm.It can also be used as high temperature adhesive and high strength fiber.
Application field
Since PEI plastics has excellent comprehensive and balanced performance, PEI plastics has been applied to the departments of electronics, motor and aviation, and used as metal substitute materials for traditional products and cultural life supplies.Using PEI plastics instead of metal to make optical fiber connector, PEI plastics can optimize the structure of the component, simplify its manufacturing and assembly steps, and maintain a more precise size.Used in automobile industry, such as high temperature fittings for manufacturing, the high power lamp and light, control the car cabin outside temperature sensor (air conditioning temperature sensor) and the control of air and fuel mixture temperature sensor (effective combustion temperature sensor).Also can be used for high temperature erosion of lubricating oil vacuum pump impeller, distilling apparatus that operate at 180 ℃ of ground glass joints (following), the lighting of anti fog light reflector.
