Dongguan furniture is world-famous. The export value of the furniture industry and related supporting industries reached US$9.2 billion, accounting for 40% and 69.7% of the national and provincial sales respectively. In December of this year, China Dongguan (Furniture) Intellectual Property Rapid Rights Protection Center was approved by the State Intellectual Property Office and will be settled in Houjie Town, Dongguan. It is expected to open the door to accept business in the first half of next year. The center is the first intellectual property rapid maintenance center in the domestic furniture industry and the third domestic intellectual property rapid maintenance center. Dongguan's export value accounts for 40% of the country. Dongguan City has formed a furniture industry cluster centered on Houjie Town, covering Dalingshan, Shatian, Humen, Dongcheng and Nancheng. There are 568 enterprises, accounting for 13.77% of the country; the total industrial output value of the furniture industry is 86.58 billion yuan, accounting for 16.67% of the country. “Dongguan furniture industry also has a large number of infringements, but due to the long-term solution through judicial channels, many companies have not taken action to defend their rights.†Wan Zhuope, the mayor of Houjie Town, said that the furniture industry is a fast-moving consumer industry and is applying for patents at this stage. Most of them take more than half a year, and this half year is often the golden age of furniture. After the passage of time, the significance of rights protection is not great. At present, the export value of Dongguan furniture industry and related supporting industries is 9.2 billion US dollars, accounting for 40% and 69.7% of the national and provincial sales respectively. The export value of furniture enterprises above designated size ranks first in the prefecture-level cities nationwide. Office furniture used by more than 80 heads of state around the world are produced by Dongguan enterprises. Of the 14.1 billion US dollars of furniture merchandise exports in Guangdong in 2011, about 73.4% completed orders or transactions in Houjie Town, Dongguan. It is understood that the furniture workstations of the intellectual property service center set up in Houjie Town have been mediating or transferring administrative and judicial cases to 102 cases of intellectual property disputes since July 2009, including 34 cases of furniture cases handled in 2013. Good, Houjie is fully equipped with the necessary conditions for the establishment of a fast rights protection center. According to the introduction, in 2011, Houjie Town began to organize the relevant declaration work of the rapid rights protection center. In December this year, it was officially approved by the State Intellectual Property Office. It is expected that the business will be fully accepted from March to April next year. At that time, the time cost of patent protection and application processes will be greatly reduced. China Dongguan (Furniture) Intellectual Property Rapid Rights Protection Center is a Zhengke-level institution approved by the Dongguan Municipal Organization Establishment Committee. The national, provincial and municipal levels will delegate patent enforcement authority to the center. After the establishment of the Furniture Intellectual Property Rapid Rights Protection Center, it will directly interface with the internal network of the State Intellectual Property Office, and will be handled by the State Intellectual Property Office with relevant official seals and authorizations to handle relevant patent administrative examination and approval matters. The Center for Express Rights Protection will focus on Houjie Town, covering the city's furniture industry, accepting reports and complaints, mediating patent disputes, setting up circuit courts, and conducting intellectual property service agencies, e-commerce, etc., including patent applications, rights assistance, mediation, and judicial trials. In one. Wan Zhuopei said that the center may also accept infringement and patent applications in the furniture industry outside Dongguan in the future, but it will take time to gradually clarify the specific functions.
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.
