Alumina Ceramic Part of Textile Machinery
Application Field
Textile ceramics parts which are widely using in textile machinery with high mechanical property、high hardness、long wearing、 large insulation resistance、good corrosion preventive 、high temperature resistant.
Textile ceramics parts have a wide range of applications in daily life. We say almunia ceramics parts can be used in processes such as yarn interlacing, drawing, spinning, plasticization, weaving, and knitting and so on. China is biggest market of textile ceramics parts. In addition ,the competitive domestic textile ceramic accessories industry is also constantly changing.
Some domestic enterprises have gradually narrowed the gap with foreign brands through technological research and development and quality improvement, and their market share has gradually increased. At the same time, some foreign brands have gradually entered the Chinese market, further promoting the textile ceramic accessories industry.
