Access conditions for the glass fiber industry

in order to effectively curb the low-level repeated construction and blind expansion of the glass fiber industry, standardize the order of market competition, and promote the upgrading of industrial structure, according to the relevant national laws and regulations and industrial policies, and in accordance with the principles of structural adjustment, effective competition, low consumption, environmental protection and safe production, the following access conditions are proposed for the glass fiber industry

I. layout of production enterprises

the automobile interior of the newly-built glass fiber production enterprise will also bring a different experience to users. The location of the industry must comply with the overall land use planning, town planning and industrial layout planning. Glass fiber production enterprises shall not be built in areas where industrial enterprises are prohibited by laws and regulations, such as scenic spots, ecological reserves, natural and cultural heritage reserves, and drinking water source reserves, as stipulated by the State Council, relevant state departments, and the people's governments of provinces (autonomous regions, municipalities directly under the central government). Such SiC particle reinforced MoSi2 matrix composites are forbidden to build new glass fiber production enterprises in urban built-up areas and Urban Non industrial planning areas

the glass fiber production enterprises that have been put into production in the above-mentioned areas should gradually withdraw by means of "relocation and production conversion" according to the regional planning

II. Process and equipment

(I) the scale of the new glass fiber tank furnace farad wire production line must reach 30000 tons/year and above. The newly-built glass fiber instead of platinum crucible drawing production line must be glass fiber with special components, or spinning yarn with monofilament diameter less than 7 microns, and the product quality and specification should meet international standards, and the production scale should not be less than 2000 tons/year

(II) it is forbidden to build new alkali free and medium alkali glass ball production lines. When glass fiber enterprises in areas with advantages in resources and energy are rebuilding and expanding alkali free and medium alkali ball kilns, the scale of single kiln production line should reach 20000 tons/year and above. White arsenic is forbidden to be used as clarifier in glass melting process. If you have oil funnel, you must comply with the provisions of mandatory industry standards. If you rebuild and expand glass ball kilns with special ingredients, the scale of single kiln production line should not be less than 3000 tons/year

(III) the newly-built glass fiber products processing enterprise has an annual sales revenue of more than 20million yuan/year. It is forbidden to use textile equipment eliminated by the state to weave glass fiber products, and it is forbidden to use ceramic crucible glass fiber drawing products to produce glass fiber products

(IV) immediately eliminate the production process and equipment of glass fiber drawing with clay crucible according to law, and prohibit the production and sale of high alkali glass fiber products

III. energy consumption

(I) the unit energy consumption of the new glass fiber tank furnace farad wire production line is ≤ 1 ton of standard coal/ton of precursor

(II) the reconstruction and expansion of alkali free glass ball kiln must adopt advanced furnace melting process and heat preservation and energy saving technology, and the unit energy consumption is ≤ 580 kg standard coal/ton ball

(III) in the reconstruction and expansion of alkali glass ball kiln, advanced furnace melting process and heat preservation and energy saving technology must be adopted, and the unit energy consumption is ≤ 300 kg standard coal/ton ball

IV. environmental protection

(I) the emission of air pollutants must meet the requirements of the national discharge standard of air pollutants for industrial furnaces (GB), the integrated discharge standard of air pollutants (GB16297-1996), and the discharged sewage must meet the requirements of the integrated discharge standard of sewage (GB) and the relevant local environmental standards

(II) the waste liquid of wetting agent and cooling water in the production of glass fiber and glass ball must be recycled for comprehensive utilization

(III) after the state issues the relevant emission standards of pollutants from the glass fiber industry, the emission of pollutants from the glass fiber industry should be implemented in accordance with the requirements of the new standards

(IV) the waste silk produced by glass fiber drawing, warping and weaving processes should be recycled and should not be disposed of by landfill

(V) the contents of toxic and harmful substances, heavy metals and arsenic trioxide in glass fiber components must meet the requirements of relevant standards

(VI) dust removal, desulfurization and denitration pollution control facilities should be reserved for new, reconstructed and expanded glass fiber production lines
