Metal sintered mesh is generally divided into five layers,Divided into four layers: protective layer, filter layer, separation layer and support layer. it is thicker than common mesh.The filter material has uniform and stable filtration precision and high strength and rigidity. An ideal filter material for high pressure resistance requirements and uniform filtration particle size requirements.

Before 2016, LED chip manufacturers have expanded their business, resulting in overcapacity, and prices continue to decline rapidly, causing drastic changes in the LED industry. Many small enterprises with poor management have reduced production or transformation due to backward technology and other reasons, and a large number of LED companies have withdrawn from the market. Before 2016, LED chip manufacturers have expanded their business, resulting in overcapacity, and prices continue to decline rapidly, causing drastic changes in the LED industry. Many small enterprises with poor management have reduced production or transformation due to backward technology and other reasons, and a large number of LED companies have withdrawn from the market. At the same time, the state's subsidies for MOCVD equipment have been reduced, and small enterprises lacking funds have been unable to expand production. The profits of overseas LED chip manufacturers have also fallen sharply, and the gross profit margin of products is low. However, since 2016, with the steady growth of demand, the supply and demand relationship of the LED industry has gradually improved, and in recent days there has been an intensive product price increase. Industry insiders said that not only LED chips are rising in price, but also screens are rising. Previously, manufacturers were too conservative in demand forecasting, resulting in insufficient capacity preparation. At the same time, intelligent products expanded rapidly, and the demand for products such as chip screens increased significantly. The superposition of these factors has intensified the contradiction between supply and demand. A letter of contact issued by the industry with the official seal of Sanan Optoelectronics Co., Ltd. stated that it decided to raise the price of S-30MB/S-32BB series products by 8% from January 10, 2017. Xie Zhiguo, deputy director of the National Star Optoelectronics R&D Center of the packaging company, confirmed that Guoxing Optoelectronics received the price increase notice from Sanan Optoelectronics on the first day of 2017. On the one hand, the price increase of Sanan Optoelectronics is the reason for the increase in cost; on the other hand, with the withdrawal of small and medium-sized manufacturers, the LED chip industry is mainly concentrated in the hands of several large manufacturers, and the seller status is stronger. According to the "LED industry market prospects and investment strategy planning analysis report" analysis, by the end of 2017, the effective production capacity of LED chips is about 83.28 million pieces, and the demand is about 92.35 million pieces. Among them, the demand for lighting chips is 47.04 million, up 20% year-on-year; the demand for outdoor full-color displays is 26.02 million, up 5% year-on-year; the demand for small indoor space is 1.02 million, up 50% year-on-year; the demand for mobile phone backlights is 1.39 million. There are 440,000 tablets for backlighting, 6.99 million for computer and TV backlights, and 1.06 million for automotive lamps.
