Erogba Okun Production Ọna

Ni asiko yi, industrial production of carbon fiber can be divided into three categories according to the raw material route: polyacrylonitrile (PAN) -orisun erogba okun, ipolowo-orisun erogba okun ati viscose-orisun erogba okun. Erogba okun se lati viscose awọn okun gbọdọ wa ni graphitized nipa ga-otutu nínàá. Awọn carbonization ikore ni kekere, awọn ọna ti jẹ nira, awọn ẹrọ ti wa ni idiju, ati awọn iye owo jẹ ga. Awọn ọja wa ni o kun lo fun ablative ohun elo ati ki ooru idabobo ohun elo. Erogba okun ti wa ni produced lati idapọmọra pẹlu ọlọrọ aise awọn ohun elo awọn orisun ati ki o ga carbonization ikore. sibẹsibẹ, nitori awọn eka igbaradi ti aise ohun elo ati kekere ọja išẹ, o ti ko ti ni idagbasoke lori kan ti o tobi asekale. Ga-išẹ erogba okun le se lati polyacrylonitrile okun awasiwaju. The production process is simpler than other methods, and the product has excellent mechanical properties and a wide range of uses. Therefore, it has made great progress since its introduction in the 1960s and has become today The mainstream of carbon fiber industrial production.

The production of polyacrylonitrile-based carbon fibers mainly includes two processes of raw silk production and raw carbonization. The production process of raw silk mainly includes the steps of polymerization, defoaming, metering, spinning, traction, water washing, oiling, drying and collection. The carbonization process mainly includes processes such as laying, pre-oxidation, low-temperature carbonization, high-temperature carbonization, surface treatment, sizing and drying, and winding and winding. According to different product specifications, carbon fiber is currently divided into aerospace-grade and commercial-grade, also known as small-strand tow or small tow and large tow -strand tow or large tow) Carbon fibers above 48K are often referred to as large tow carbon fibers, including 48K, 60K, 120K, 360K and 480K. Astronautics-grade carbon fiber is mainly 1K, 3K, 6K. The development of 14K and 21K is mainly used in defense military and high technology, as well as sports and leisure products, such as aircraft, missiles, rockets, satellites and fishing rods, golf clubs, tennis rackets and so on. Industrial grade carbon fiber is used in different civil industries, including: textiles, medical and health, mechanical and electrical, civil construction, transportation and energy.
