Taihe Xincai (002254), the largest high-performance fiber manufacturer in China, cooperated with Austrian Lansing Company to jointly develop flame-retardant protective clothing market. On March 15, the two sides signed a strategic cooperation agreement, which will draw on the successful experience of the application of aramid fiber and FR fiber in European and American markets to intensively cultivate the protective apparel market.
Lenzing Co., Ltd. is the world's largest manufacturer of high-grade cellulose fibers. The famous Modal and Lyocell fibers are popular throughout the world. Its FR thermal protective viscose fiber is widely used in special protective clothing in high-risk areas and enjoys an international reputation. The company cooperated with Lenzing Co., Ltd. several years ago in the field of oil-fired tooling and arc-proof clothing. The company's Taimeida meta-aramid and FR two high-performance flame-retardant fibers complement each other and become safe and comfortable. The perfect match for flame-retardant protective clothing.
As an important personal protective equipment, safety protective clothing has a global demand of 100 million sets each year, and is increasing at an average annual rate of 2 digits. It is widely used in petroleum, chemical, metallurgy, shipbuilding, fire fighting, and military fields. According to Li Lingshen, president of the China Association of Industrial Textiles, in addition to fire protection suits and international use of aramid fabrics in the field of personal protection in China, safety protection garments for other industries are basically based on cotton or polyester fabrics. There are widespread defects such as rapid decrease in flame retardancy after washing, short service life, low temperature resistance, and poor comfort. The new safety protective clothing and flame-retardant fabrics have a wide range of applications and high added value. The demand for special safety protective clothing in the domestic labor protection industry is more than 20 million sets per year, and the market growth rate is more than 25%.
The company is the largest interposition aramid production enterprise in China. The developed Thaimeta meta aramid has been applied in batches in the National Forest Armed Police Fire fighting suits, urban fire fighting suits, special police training suits, high temperature resistant tooling, and public places fire retardant Safe textiles and other fields enjoy a relatively high share in the domestic market.

CBN abrasive is mainly used for steel parts, such as high speed steel, die steel, 45 steel, etc., can be made into electroplating CBN, resin CBN, sintered CBN. Can be made into grinding wheel, cutting pieces, grinding head. Abrasive sharp, high temperature resistance, good thermal stability, wear resistance. The hardness of CBN is higher than that of ordinary abrasives and the ability to maintain shape is one of the main characteristics of high performance abrasives. CBN is very resistant to pressure. CBN has good thermal conductivity and can achieve cold cutting during grinding.
strong wear resistance, long life
The grinding ratio of CBN wheel can reach 3500-5500, which is 100 times higher than that of ordinary corundum wheel and 3-5 times higher than that of diamond wheel.
environmental protection, no pollution, energy saving and consumption reduction
No too much powder dust.
High work efficiency and good comprehensive economic benefits
The grinding is sharp, the grinding force is small, the dressing cycle of CBN wheel is long, the dressing amount is less, and the replacement time is long. Long service cycle, high grinding ratio, can obtain better economy, good shape retention in use, do not need to change and trim grinding wheel often, save working hours, improve working conditions, is conducive to machining operation.
Cubic boron nitride is not suitable for grinding hard metals and non-metallic materials. At high grinding temperature, CBN will react with alkaline aqueous solution. CBN grinding wheel will decompose in alkaline solution at 300℃, and can decompose in trace amount in boiling water, which will destroy the crystal shape of grinding grains. Therefore, oily coolant should be used instead of water-based coolant during grinding.
