This week, the price of strong prices has increased sharply. The latest price of Anhui Jinhe 98% was 2,500 yuan/ton, which was a 35% increase in the week before. Good strong ** listed companies combined chemical 13.49,1.23,10.03%.
Methanol prices continued to soar this week, rising by 200-400 yuan across the country, mainly due to the increase in external disk prices and the increase in downstream operating rates of formaldehyde. The price of coal at the coal head increased by approximately RMB 400/t.
Soda ash prices have been climbing all the way this week, with limited company start-ups and a decline in production, causing supply to shrink. The difference between the soda method and the soda method rose by around 300 yuan. Soda ash prices have risen too quickly in the near future and the downstream capacity is limited. At the same time, downstream glass companies have stepped up their stocking, and the trend of future soda ash prices needs to be watched. Concerned about the Shuanghua Listed Company Shuanghuan Technology 8.90, 0.54, 6.46%.
Polyester prices have been high this week. The price of upstream PTA and MEG dropped slightly, and the spread of polyester PET increased by RMB 200/t. It is expected that polyester prices will remain high in the short term. However, the gap between the supply and demand of the cotton market is difficult to make up for, and the demand for polyester staple fiber alternatives appears to be in demand. Therefore, the price of polyester staple fiber will continue to remain high. Focus on Huaxi Village 10.17,0.27,2.73%,Xiaoke Environmental Protection 12.58,0.14,1.13%.
Vinyl acetate prices rose, the spread widened, and the weekly average spread rose by 300 yuan/ton. Upstream calcium carbide prices rose by 150 yuan/ton this week.
The downstream demand for pure MDI increased and the price rose sharply. East China MDI price rose 8.8% in the week. The spread rose by 10%. Pure MDI is unlikely to fall back in the short term.
The shutdown and overhaul of the BDO equipment of Shanhua and Nanjing Bluestar tightened the supply in the domestic market, and the market demand for downstream slurry was good. The domestic calcium carbide BDO spread average weekly price rose 5.4%, maleic anhydride BDO spread average weekly price rose 6%. It is expected that the domestic BDO market will maintain its strength in the next week, but it will continue to pull up a lot of resistance. Focus on the three dimensions of Shanxi 10.28, 0.15, 1.48%.
Domestic energy-saving emission reduction and export drive, urea prices began a new round of upward adjustment, the average weekly price rose 500 yuan / ton. Manufacturers inventory is low. It is expected that the price of urea will be in a steady upward trend for some time in the future. The average weekly price spread rose by 50 yuan/ton.
The price of cotton linters rose sharply this week, up by RMB 600/ton from the previous week. Staple fiber prices rose by 500 yuan/ton. The difference between staple fiber and pulp prices has advanced. The price of viscose staple fiber is mainly driven by cost. Affected by the overhaul and reduction of production by some companies, it is expected that prices will further increase next week.
This week, the spread of PVA slightly expanded. The spread of diethanolamine glyphosate has slightly increased.
Variety of stable spreads Glyphosate varieties of reduced price acetic acid, coal-based dimethyl ether, phosphate fertilizer DAP, PVC, yellow phosphorus, polymer MDI, TDI, DMF, silicone DMC, PTA, spandex 40D.
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.
