ChemOrbis reports: Due to the tight supply in the market, the recent spot price of styrene in Europe has risen to turbulence. Since entering October, its cumulative increase has reached as high as $200/ton.

At the end of September, the European styrene market price remained in a downturn, the lowest since December 2012. In the following days, styrene prices in the region began to rebound strongly. On October 10th, FOB Northwest Nordic styrene spot price exceeded 1700 US dollars / ton mark, a record high in nearly a year.

Last weekend, Shell Chemical announced that its Moerdijk production plant in the Netherlands was forced to suspend styrene production due to accidental force majeure. Previously, on October 2, part of the plant's cracker was interrupted due to gas leakage. It is reported that the styrene capacity of the Moerdijk plant is 450,000 tons/year. Shell said that the factory will have to resume production at the end of the year.

In addition to the styrene production unit, the propylene oxide/styrene monomer production unit from Shell and BASF's joint venture subsidiary Ellba is also installed in the Moerdijk plant. The plant has a capacity of 550,000 tons/year.

Coincidentally, during the parking at the Shell Moerdijk plant, some of the production facilities at Versalis, another large European styrene producer in Mantua, Italy, are still in service. The plant has a styrene capacity of 200,000 tons per year.

On the upstream side, the prices of raw materials have fallen steadily. Affected by the energy market, European benzene prices fell slightly last week. Brent crude has fallen for three consecutive weeks. On October 10, its futures trading price was $88/barrel, a record low since December 2010.

Downstream, after some producers slightly raised prices at the beginning of this month, market participants predict that the price of the European PS market will stabilize in the next few days. This will also have an impact on the styrene market trend in the region.

 

High Speed Door Motor And Control Box

Our company have German SEW Motor, Japan Mitsubishi Controller. Our own brand Hofic servo motor and controller. Chinese famous brand SEJ motor and Holip controller.

About our German SEW Motor and Japan Mitsubishi Controller: It is easy to find the ideal energy-efficient motor for your application at SEW. The series has a suitable design in its range for the globally applicable efficiency classes. Select the power and frequency within this motor design and you have already taken care of the most important selection criteria.All other motor options are of course available independently of the efficiency class. A comprehensive braking concept and cost-optimised built-in encoders ultimately complement the motor range. Comprehensive braking concept and combinations i.e. up to three different brake sizes per motor size featured in the range: Cost-optimised built-in encoders integrated into the motor. Motors for efficiency classes IE1 to IE4.Compact design saves space and costs. Future-proof, also as regards environmental protection (standards). Reduction in operating costs when using energy-efficient motors; our energy-efficient motors conform to the efficiency classes.

About servo High Speed Door Servo Control System: Our rolling gate servo control system is suitable for high speed and high usage soft and hard rolling gate. The whole system is in a small and light package, it has high torque and high operating speed, lower noise, high reliability, smooth and soft operating curves, it`s suitable for high speed and usage environment. The rolling curtain can be controlled by pull switch, push button, Bluetooth, ground radar, ground magnetic sensors. Operating Speed: 1M/s; Operating Width: ＜16 ㎡; Daily operating time: ＞2000 time; Rated voltage: 220v; Rated Output: 0.75 KW/1.5KW.

The system can operated via: 1) control box; 2) inching electronic control; 3) continuous automatic operation; 4) emergency stop; 5) single side operation box; 6) time delay; 7) ground radar and/or magnetic sensors. Please refer to Wiring Terminal for eternal connections.

System has fuse/safety wire shutdown switch for three-phase power protection, fuse/safety wire for operating circuit protection, and temperature sensing relay for motor protection.

Stroke Controller utilizes absolute value encoder. Connect the absolute value encoder and reducer via encoder`s axle, and fix the wings on to the reducer, than insert the aviation plug into plug receptacle.

The mounting screw for the control box must inspect regularly to prevent screw been getting loose and falling off. Check the internal and external wirings. Check and change the oil for the redactor on regular basis.

Precision: The system use Full closed-loop servo control and Double Encoder design. This is to ensure long operating life and to prevent overshooting during operating.

Stability: The system utilizes integrated design concept, in order to simplify internal wiring and prevent any function caused by wiring and terminal connections.

High Speed: Motor max speed is 2500 rpm; door max operating speed is 2 m/s.

Smooth: The torque servo system can adjust torque to the load automatically, and its speed curve mode step less speed regulating to ensure a smooth operation.

About SEJ motor and Holip controller: Three-phase asynchronous motor with magnetic brake has broad uses, It is suitable for various mechanical main drive and auxiliary drive, and it is also used for various required rapid stopping and correct positioning. The braking time within 0.2 second. Electric motor is added the DZM series direct current electromagnetic arrester by the basic series(Y series) electric motor.The protection class of electric motor part is IP44,the arrester part is IP23.if be applicable to bad environment can also make the arrester part into IP44,but customer have to put forward a special request while ordering,the manufactory can design a manufacturing exclusively. Its structure diagram is picture 1 and 2,picture 1 is the structure with hand release.Picture 2 is the structure without the hand release.Its operating principle BE, after being to make the retardation coil(6)to connect direct current power supply,because of the function of electromagnetic force,electromagnet(7)attract gag bit(5),and compress spring(24),make arrester disc(2)away from the friction surface of the gag bit(5)and shield(26)(the electrical motor can immediately operate normally).When the power supply cuts off after,the electromagnet(7)loses electromagnet force,the spring(24)releases the gag bit(5)and compress tightly to arrester disc(2),the arrester function,stop(the motor shaft)quickly,make electric motor shop turning to move,for the second time connect power supply will repeat above-mentioned action.
