Coarse Screen And Fine Screens
This is a kind of advanced solid-liquid separation device in water treatment, which can continuously and automatically remove debris from wastewater for sewage pretreatment. It is mainly used in municipal sewage treatment plants, residential quarters sewage pretreatment devices, municipal sewage pumping stations, waterworks and power plants, also it can widely be applied to water treatment projects of various industries, such as textile, printing and dyeing, food, fishery, paper, wine, butchery, curriery etc.

The pressure of overcapacity With the abundant resource advantages and the unrivalled cost and price advantage of ethylene PVC, China's calcium carbide PVC industry has achieved rapid development in recent years. In 2001, the calcium carbide process PVC production was only 1.6 million tons, accounting for 53.7% of the total domestic PVC production in the same year. By 2006, this figure reached 5.94 million tons and 71.4% respectively, with an average annual increase of 868 thousand tons. At the same time of significant increase in output, the capacity growth rate is faster. By the end of 2006, China's total PVC production capacity has reached 11.58 million tons, of which the calcium carbide process PVC production capacity exceeds 8.1 million tons.
According to the data released by the China Chlor-Alkali Association, from 2007 to 2008, China's calcium carbide process PVC production capacity will still increase 7.895 million tons. Among them, more than 4 million tons of projects such as Yibin Tianyuan, Yili of Inner Mongolia, Henan Aerospace, and Xinjiang Tianye Phase I will be completed and put into production in 2007, bringing the total domestic PVC production capacity to over 15 million tons in 2007, and the output is expected to exceed 10 million tons. In 2008, more than 4 million tons of projects such as Yankuang Yulin, Tianqiao Chemicals and Xinjiang Tianye Phase II were completed and put into production. At that time, the output would increase again to 12 million tons. In this way, this year's domestic PVC will have a slight oversupply on the basis of a basic balance last year, and the oversupply will be very obvious next year.
Cost pressures
About 1.5 tons of calcium carbide is needed for each ton of PVC produced. Since 2004, for the blind expansion of capacity in the calcium carbide industry, the small scale of enterprises, the low utilization rate of energy resources, and the serious environmental pollution, the National Development and Reform Commission jointly with related departments has repeatedly adopted the implementation of differential electricity prices, restricting bank loans and forcing the demolition of backward calcium carbide furnaces. Such measures have led to a significant reduction in the production capacity of the lagging calcium carbide. Since last year, since the four major calcium carbide production sites in Shanxi, Shaanxi, and Inner Mongolia have banned or forced companies to shut down their calcium carbide production capacity by more than 1.8 million tons, the national calcium carbide production growth has clearly and continuously declined since July this year. Affected by this, the price of calcium carbide continues to rise since April this year. Currently, the ex-factory price of calcium carbide is generally around 2,700 yuan (ton price, the same below), which has increased by 500 to 700 yuan compared to the beginning of the year. This alone makes the cost of PVC enterprises. An increase of 1,000 yuan.
In the future, with the increase in the management, rectification, and elimination of the calcium carbide industry in various regions, domestic calcium carbide production capacity will be further reduced. In addition, large quantities of calcium carbide raw materials will be required for PVC plants that are put into production in the next two years. The ultimate result will inevitably lead to the continued rise in calcium carbide prices. . It is estimated that the domestic ex-factory price of calcium carbide will exceed 3,500 yuan in the next year, and the cost of raw materials for PVC enterprises will increase by 1,200 yuan.
The pressure of energy conservation and emission reduction According to the "Eleventh Five-Year Plan" requirements, by 2010 China's energy consumption per unit of GDP will drop by 20% compared with 2005, and the total discharge of major pollutants will be reduced by 10% compared with 2005. The task of energy conservation and emission reduction in various regions is very arduous. In order to ensure the realization of the “Eleventh Five-Year†energy-saving and consumption-reduction and pollutant discharge indicators, it will inevitably further increase the efforts to rectify the high-energy-consuming and highly-polluting industries as a major emitter of water, electricity, waste water, waste gas, and waste residues. The PVC industry will undoubtedly become the main target for the government’s governance and rectification after the relay stone industry. Calcium carbide process PVC companies will face increasing energy-saving emission reduction and environmental protection pressure, and some may even be eliminated due to energy-saving and emission-reducing, environmental protection is not up to standard.
The pressure of export tightening is to curb the export of "two high and one capital" products. In the past two years, China has repeatedly adjusted the export tax rebate policy for products including plastic raw materials and their products. On September 15, 2006, the export tax rebate rate for plastic raw materials and products fell from 13% to 11%; on July 1 this year, the export tax rebate rate for plastic raw materials and products was reduced from 11% to 5%; July 23, In addition, the plastic raw materials and products were included in the newly-added export catalog of processing trade restrictions. This shows that the country will increasingly control the export of plastic raw materials and products including PVC, and the future export of PVC and its downstream products will still be severely restricted, and it may even be completely cancelled by the remaining 5% of export tax rebates next year. Concessions, which will inevitably intensify the domestic oversupply contradiction, so that PVC companies are facing fierce market competition and harsh survival test.
Therefore, calcium carbide process PVC companies should not indulge in the immediate joy, should fully recognize the industry's future facing the severe situation and challenges, and take precautions. On the one hand, we must strictly control the excessive growth of production capacity. On the one hand, we must adopt technological transformation and technological advancement, and take the clean production path of energy conservation and consumption reduction, environmental friendliness, and comprehensive treatment and recycling of “three wastesâ€. Qualified enterprises should, as far as possible, acquire and reorganize calcium carbide enterprises under their own subsidiaries, and build their own cogeneration projects through the treatment of “three wastes†to minimize costs and face the market. competition.
In recent years, calcium carbide process PVC has achieved considerable development under the strong growth of downstream demand and the rise in international oil prices that has caused ethylene prices to remain high. In the first half of this year, the net profit of domestic major PVC companies such as Xinjiang Tianye, Yingteli, Nanhua, Zhongtai Chemical, and Yili Hi-tech increased by more than 25% year-on-year, and some even exceeded 50%. Various economic and technical indicators are at the highest level in history. However, various indications indicate that the good days for the calcium carbide process PVC companies are coming to an end and that they will face four major pressures next year.
