Graphite products with good adsorption. Void structure enables carbon has good adsorptive carbon, it is often used as an adsorbent material of carbon graphite Lacey quality, for adsorbing moisture, odor, and other toxic substances. We did experiments Qingdao graphite, graphite used a few days before the barbecue hotplate looks very clean, but the price put on the cooker heating roughness graphite, oil and hazardous substances will see the last barbecue adsorption will slowly seep out, but do not worry, wipe clean with a clean paper meal can be used. Pure charge subcooling large, is not conducive to the nucleation of graphite graphite precipitation, less float. The main measures should be controlled to prevent the carbon equivalent according to the casting wall thickness; when small pieces of the wall thickness of not more than 30mm, appear critical carbon graphite floating equivalent of 4.7% - 4.9%; when the wall thickness of 30 to 100mm, appear critical carbon graphite floating equivalent of 4.5% - 4.6%; float appeared critical graphite carbon equivalent of 4.4% ~ 4.5% when the large wall thickness greater than 100mm. In particular, to control the carbon is less than 4. O%; the appropriate use of scrap, pig iron and silicon lower back with the use of charge; controlling the residual amount of rare earth is not too high; pouring temperature control; large cross section castings may be appropriate to add molybdenum or partial placement also prevents cold iron graphite float (see carbon equivalent cast iron, ductile iron). Nature there are no pure graphite, which often contain SiO2, Al2O3, FeO, CaO, P2O5, CuO and other impurities. These impurities often appear to quartz, pyrite, carbonate and other minerals form. In addition, water, bitumen, CO2, H2, CH4, N2 and other gases portions. Therefore, the analysis of graphite, in addition to the fixed carbon content was measured, it must also determine the content of volatile matter and ash at the same time. Carbon graphite, carbon industry in the North Sea Dragon (certified), graphite is provided by Carbon Co., Ltd. Weifang Sea Dragon. Carbon Co., Ltd. Weifang Sea Dragon (www.longmentanye.com) Shandong Weifang, graphite and carbon products leader, over the years, the company is implementing the scientific management, innovation and development, the principle of honesty and trustworthiness, and satisfy customer needs. In the North Sea Dragon carbon industry leadership with the staff warmly welcome all inquiries negotiations to create the North Sea Dragon carbon industry a better future.
