In May, the chemical market continued to bottom. According to relevant data, 44.1% of chemical products prices fell, 39.7% of product prices held steady, and only 16.2% of product prices rose. Analyst Zhang Ming believes that the current major problem in the chemical market is insufficient demand. Some products will gradually enter the export concentration period in the next two months. The chemical market is expected to stop sliding at the end of June and beginning of July, and it will rebound for the third quarter. Saving power.
The data show that after the chemical industry index broke the bottom of 2012 in early May, it further fell to 921 points on May 30. The products with the most recent declines included ammonium sulfate, **, n-butanol, crude, coking benzene, and sin. Alcohol, DOP, pure benzene, urea, etc. However, products such as **, **, **, phenol, styrene, glyphosate, etc. are sticking to the rising camp for two consecutive months.
In some industries, due to the increase in shutdown and overhaul, the industry's operating rate has decreased, market supply has decreased, and the price trend has been relatively satisfactory. Devices such as propylene oxide and styrene will enter the maintenance season in May. The role of cost promotion is obvious in individual industrial chains. For example, the increase in price of epichlorohydrin this month is mainly due to the upward trend in prices of raw materials** and propylene, and the need for manufacturers to pass on cost pressures is more urgent.
Industrial sectional doors are the most durable and longest lasting doors to ensure circulation at the areas of the factory entrance and exit of goods, loading and unloading areas.
The body of sectional door is forming by 40 mm sandwich panels. These panels provides sound and heat insulation due to the intense doped polyurethane insulation was injected between galvanized steel sheet. (50 kg/m3).
Industrial sectional door systems provide space-saving with opening parallel to the ceiling.Any opening can be used clearly . and produces in accordance with the transition range and the height in the factory buildings or warehouses.
Doors is working sliding by be the most appropriate the gap between the top level of the gate with a ceiling height within the side rasils. The door can be mounted in different ways according to the gap distance (standard, low, highlift and vertical track systems).
Industrial sectional doors can easily be opened automaticly by 230-380 V-AC/50 Hz electric motor or manualy thanks to torsion spring system that balances the weight of the door.The galvanized springs are made to be durable of 25.000 door cycles.Motor with emergency chain All the drive systems have a mechanical back-up system fitted to the reduction gearbox of the electric motor, so that the sectional door can be opened if the power fails. The reduction gearbox can then be powered using the chain.
