Aramid paper was selected as an urgently needed material for advanced rail transit

In order to accelerate the development of the new materials industry, the three ministries and commissions of the National Development and Reform Commission, the Ministry of Finance, and the Ministry of Industry and Information Technology recently jointly issued the "Implementation Plan for the Upgrading and Upgrading of Key Materials".Among them, aramid paper was selected as the “material urgently needed in the advanced rail transit industry” for its good performance and broad market space. The “Plan” clearly stated that "it supports the industrialization and demonstration application of aramid paper for honeycomb core materials. The tensile strength of aramid paper is greater than 3.2 kN/m, the temperature resistance exceeds 210 ℃, the flame retardant grade is VTM-0 or V-0, and the annual production capacity of aramid paper reaches 1,500 tons."   In recent years, with the rapid development of the high-speed rail industry, the related new material industry has ushered in a wave of rare development opportunities.As an important structural material, the honeycomb structural material made of aramid paper has the characteristics of flame retardant, corrosion resistance, high strength, lightweight, excellent sound insulation and noise reduction. Its specific strength is 9 times that of steel and higher than that of aluminum honeycomb.It is widely used in the floors, side walls, ceilings, window frames, luggage racks and various cabinet mezzanines of high-speed rail and motor vehicles, and has become an indispensable strategic new material.   As a leading enterprise in the domestic aramid paper industry, Yantai Minshida Special Paper Co., Ltd. currently has a production capacity of 500 tons of aramid paper, and the expansion project of more than a thousand tons has been put on the agenda. As early as 2011, the company's Metastar® Aramid paper products have passed the certification of UL in the United States.The company said that it will make full use of the golden opportunity for the development of the industry, accelerate the promotion of aramid paper in rail transit, aerospace and other related fields, and make due contributions to promoting the upgrading of the material field and the development of the rail transit industry.

Minshida was awarded a carbon fiber paper invention patent

Recently, the invention technology of Yantai Minshida Special Paper Co., Ltd. “An electric heating high temperature resistant carbon fiber paper and its preparation method” was authorized by the Patent Office of the State Intellectual Property Office (Patent number: ZL201310428212.5).This patent right is very innovative and practical, and will become another important core technology of the company.   Unlike traditional papermaking technology, the dispersion and forming problems of carbon fiber are very prominent, and it is almost impossible to form paper independently, making the production process more complicated.At present, only a few countries can mature the manufacture of high-performance carbon fiber paper in bulk. The country basically relies on the import of high-performance carbon fiber paper from Toray Company in Japan or SGL Ballard Company in Canada, and the number of imports is strictly limited.   Carbon fiber paper has excellent electric heating properties.After carbon fiber paper is energized, it has excellent heating properties under appropriate resistance and voltage. Its heating temperature range is usually 30-250℃, and the electric heating conversion efficiency is >97%, which is 15%-30% energy-saving than traditional materials. There is also a performance that other heating materials cannot match. Its far-infrared electricity-thermal radiation conversion rate is >70%, and it also emits 5-20µm far infrared rays, which are far-infrared waves that adapt to human blood circulation and have health functions.Unlike the wave permeability of aramid, carbon fiber has the ability to shield electromagnetic waves.Therefore, carbon fiber paper is a kind of sheet-like heating material with great development value.Depending on the carbon content, it can be used as electromechanical materials, new energy materials, high-efficiency heating materials, electromagnetic wave shielding materials, anti-static packaging materials, and aircraft structural materials.   After years of hard work, the technical team of Yantai Minshida Special Paper Co., Ltd. has successfully implemented the pilot technology of “electric heating and high temperature resistant carbon fiber paper” manufacturing. Minshida® carbon fiber paper uses Taimeida® Aramid sedimentation fiber as the bonding material. The product itself has the advantages of carbon fiber and Aramid, two high-performance fibers. In addition, there are no other bonding components.The company said that it will make full use of the advantages of existing specialty paper resources, and at the same time, actively integrate various resources in the industry to strive for the project to enter the industrialization stage as soon as possible.

Yantai Minshida Phase II Aramid Paper Project broke ground

In October of the golden autumn, the autumn breeze was dry, and the company's Phase II aramid project project “Phase II project with an annual output of 1,000 tons of aramid paper” broke ground in full. The design capacity of the project is 1,000 tons. All projects are expected to be put into operation at the end of the third quarter of 2015.This project is the enrichment and summary of the company's industrialization experience over the years. At the same time, it will greatly alleviate the existing tight production capacity and short supply of Metastar® aramid paper products. Metastar® Aramid paper, full name “polyarylamide fiber paper”, is a high-performance composite material made of aramid fiber. It has the characteristics of flame retardant, insulation resistance, high strength, and corrosion resistance. It is widely used in electrical insulation, aerospace and rail transit fields. It is an irreplaceable strategic new material. After more than 5 years of market development and development, Metastar® aramid paper has been used and recognized by more than 200 customers around the world, and the company has become the largest supplier of aramid paper products in China. The expansion of aramid paper production will further improve the company's ability to guarantee the supply of downstream customers' products, and enhance the company's industry status and comprehensive competitiveness.
