Value Added Products

As one of the major value-added products of coal processing and utilization, coal pitch coke and coal tar pitch are used as raw materials to prepare high-purity graphite. The structure characteristics and properties were measured by experiments. The results show that the high-purity graphite has excellent physical properties: the skeletal density of 1.81–1.91 g/cm3, the Shore hardness of 45.5–66.6 Hs, the flexural strength of 33.0–46.1 MPa, the compressive strength of 65.6–75.8 MPa, the ash content of 67–181 ppm, the thermal expansion coefficient of 3.71–4.11 × 10–6/°C, and the electrical resistivity of 8.72–12.13 μΩ · m. Consequently, coal-based graphite materials have excellent properties and good application prospects in solar energy industry, which is an effective exploration for the transformation and upgrading of Chinese coal industry.

Abstract Laboratory tests were made to determine the leaching effects of high purity water on plastics and other materials used in building or lining of high purity water storage tanks. Specifically tested were enamels used in painting interiors of condensate storage tanks, materials used for filter tubes, plastic and metal materials of construction, and miscellaneous coating and linings materials. Materials tested include polyethylene, epoxy resins, phenol-formal-dehyde resins, cotton, cellulose acetate, glass fiber, mineral rubber with inert filler mixture, asphalt clay-cement mixture, polyvinyl over sprayed zinc and aluminum, sprayed zinc and aluminum, hydraulic cement, commercially pure aluminum, and coal tar enamels. 4.6.5
