Statistics show that from January to June this year, except for hydrochloric acid, soda ash, and other individual varieties, Shaanxi Petroleum and Chemical Industry showed a year-on-year increase in the output of other products. The industry's total industrial output value was 10.2145 billion yuan, an increase of 43.27% year-on-year. The country is in a leading position. Hu Haifeng, president of the Shaanxi Provincial Petrochemical Industry Association, told the reporter that while the petrochemical industry in Shaanxi Province has been developing at a high speed, remarkable results have also been achieved in structural adjustment and transfer.
The product structure is continuously optimized. In the first half of the year, 150,000 tons/year of glacial acetic acid and Shanhua Group's 30,000 tons/year 1,4-butanediol project were successfully put into operation by Yulin Excellence Energy Chemical Company. Recently, the 600,000 sets/year radial tire production line of the Oil Group Rubber Company was extended. Throughout the entire line, these are to fill the blank chemical products in Shaanxi Province.
The pioneering new coal chemical technology has been continuously developed. For example, a new generation of methanol-based low-carbon olefin technology and Yulin medium-low-temperature coal tar-based clean fuel technology passed the results verification last month; the international cooperation project of carbon dioxide capture and storage and utilization technology carried out between Shaanxi Province and the United States and the Netherlands has also started.
The project of energy conservation, emission reduction and comprehensive utilization of resources has been accelerated. For example, the world's largest monomer and longest industrial chain, Shenhua Doosan’s Yulin circular economy coal comprehensive utilization project has entered a substantive advancement stage; it has been identified by the United Nations as an extension of the clean coal technology demonstration and extension project. Petroleum Jingbian Chemicals Comprehensive Utilization Industry Demonstration Park is under construction; Shaanxi's first fine chemical project using carbon dioxide as raw material—Zhulin Yunhua Green Energy’s dimethyl carbonate production and other projects are being implemented.
Take tough measures to eliminate backward production capacity. On the basis of exceeding the energy saving target last year, Shaanxi Province will continue to phase out outdated production capacity of 8.348 million tons this year, involving various industries such as calcium carbide, coke, and papermaking, and annually save 3.2 million tons of standard coal and 50,000 tons of sulfur dioxide emissions.
At the same time, the regional structure of Shaanxi's industrial economy is also quietly changing: the diversified development pattern of Shaanxi's energy and chemical industry base is being formed, and the coordinated development of energy, chemical and non-energy chemicals will be achieved by accelerating the development of competitive industries such as photovoltaic power generation, wind power, and biomass energy; As the second batch of resource-exhausted cities in the country, Tongchuan City will focus on cultivating four major pillar industries, including modern building materials, equipment manufacturing, materials processing, and bio-pharmaceuticals, and accelerate the upgrading of industrial upgrading; the southern Shaanxi region will focus on biopharmaceuticals, new materials, and oil and gas Chemicals and other advantages, to create ten major circular economy industrial chain.
Stamping forming technology USES punch and mould to produce the desired shape. The punch can be either mechanical or hydraulically driven, but it is best to use hydraulic transmission when it is deep, because the hydraulic presses can provide full load pressure during the stroke.
SPCC cold-rolled steel plate
Cold rolled steel is a hot rolled steel coil after pickling, which is produced by electrolysis cleaning, annealing and tempering, after the constant temperature rolling of the cold rolling mill to 0.30-3.20mm. Cold rolled steel products due to the thin thickness, size precision, surface roughness classification, more easy to painting and plating, and the mechanical properties and good processability, easy to made all kinds of sheet metal products, it USES a very wide range, suitable for car body, electronic components, household appliances, steel furniture, container, etc., all needs to use a lot of cold rolled steel products as a processing materials.
SPCC: easy to scratch, oxidize, rust, wear gloves in the process of making, spray anti-rust oil, and separate each product with bubble bag layer, usually with surface plating treatment; Do not touch the hand or dirty gloves directly after plating to prevent them from touching handprints or dirt;
SECC galvanized steel plate
Electric galvanized steel coil, substrate for general cold rolled steel coils in continuous production line after degreasing, pickling, galvanized after the process of electroplating and all kinds of post-processing, namely become electric galvanized products, the product features not only has the general mechanical properties of cold-rolled steel sheet and approximate the workability, and has superior corrosion resistance and decorative appearance; The market of electronic products, home appliances and furniture is highly competitive and substituting
SECC, a large number of communication, PC products, electronic products; Because surface is easy to scratch, in the case of not baking, special attention to the surface must not be scratched;
SECC is divided into baosteel, sinosteel, Korean materials, Japanese materials and Taiwan materials. The surface colors are different, so it is necessary to pay attention to color difference when assembling multiple materials.
SPTE tinplate
It is a kind of ultra-thin cold rolled steel plate, the main purpose is to supply the tin plating industry used in the tin plating, chrome-plated iron plate. Strong conductivity, good appearance, due to cost considerations to replace SUS, non-magnetic material, but the more pressing processing times, the stronger the magnetism.
Phosphor bronze PBS
Phosphor bronze is composed of bronze (copper tin alloy) with deoxidizer, phosphorus (P) content 0.03~0.35% and other trace elements such as Fe and Zn. Ductility and fatigue resistance are good, can be used in the electrical and mechanical materials, and corrosion resistance, reliability is higher than the general material of copper alloy products, with continuous melting casting (plate, copper roll) method, the material of high uniformity. High conductivity, high elasticity and high resistance to abrasion; It is a shrapnel and conductive material used in electric switch and terminal, but without the strength of stainless steel. Appearance must be plated.
Beryllium copper BECU
High conductivity and high elasticity are the highest hardness and strength of all copper alloys. The most suitable for high temperature and high current switch parts, belong to the age hardening material. Is the micro switch, all kinds of high-level contacts, relay and other precision shrapnel materials. Features similar to PBS, but after heat treatment, can get better hardness and elasticity, the appearance must be plating, but the cost is high.
SUS304 stainless steel
Purpose of most kinds of stainless steel, more rich than for containing Ni Cr steel, corrosion resistance and heat resistance and low temperature strength, so the mechanical properties is very good, work hardening is very large, heat treatment hardening, nonmagnetic, intensity, the less elastic, often use thickness between 0.4 T ~ 1.0 T. Therefore, at present, the Notebook is widely used in the need of structural strength, and the application must specify the series.
SUS301 stainless steel
Cr (Cr) composition is lower than SUS304, and the corrosion resistance is poor, but cold machining can get very high tensile and hardness, and its characteristic USES are broad, because of the elasticity, but the usual thickness is between 0.4T ~ 0.07 T. The series must be specified in order to meet the design requirements (such as elasticity, strength).
