China Drying Network News Ministry of Industry and Information Technology announced the “Admission Requirements for Glass Fiber Industry (Revised in 2012)â€. The new revised entry conditions were implemented from October 1, 2012, and the original access conditions were abolished at the same time. Compared with the “Entry of Glass Fiber Industry†issued in 2007, the revised “Entry Requirements†has comprehensively increased the barriers to enterprise layout, process equipment, energy consumption, and environmental protection, and increased product quality. Access requirements. In terms of process and equipment, the “Entry Requirements†is clear, the new alkali-free glass fiber tank furnace roving wire drawing production line (single wire diameter >9 microns) should reach 50,000 tons/year and above, and a new spinning yarn drawing line (single Wire diameter ≤ 9 microns) The size of a single kiln should reach 30,000 tons/year and above. It is strictly forbidden to newly build and expand the alkali fiberglass tank furnace drawing production line. Newly-built high-performance or special glass fiber production lines, the production scale of tank kiln method should reach 20,000 tons/year and above, the platinum rhodium method should reach 2,000 tons/year and above, and the product monofilament diameter should be less than or equal to 7 microns. The newly-built glass fiber tank furnace drawing wire production line must adopt advanced technologies and equipment such as pure oxygen combustion, electric fluxing, logistics automation, waste gas waste heat utilization, and simultaneous construction of environmental protection and safety production facilities. In regards to energy consumption, the “Entry Requirements†requires that the newly-built or reconstructed glass fiber tank furnace drawing production line should have a unit energy consumption roving ≤ 0.55 tons of standard coal/ton of yarn, and single-filament diameter 4 to 9 microns of fine yarn ≤ 0.75 tons of standard coal. / ton of yarn. Newly-built high-performance or special glass fiber platinum crucible drawing line unit comprehensive energy consumption ≤ 0.37 tons of standard coal / ton of yarn. The glass ball kiln must adopt advanced kiln furnace melting technology and thermal insulation energy-saving technology. The comprehensive energy consumption of non-alkali glass ball kiln units is ≤0.4 tons of standard coal/ton ball. The comprehensive energy consumption of the alkali glass ball kiln unit is ≤ 0.3 tons of standard coal/ton ball.
Black PVC Roll is in different form of PVC film compared to PVC Sheet. It has good printability, excellent dimensional stability and good light-proof property. It is frequently used in printing,vacuum forming, thermoforming and cold tower. The thickness range of PVC roll normally is from 0.18mm to 1.5mm and the maximum width is around 1500mm.
