16m Light Pole Bending 3200T Bouble Hydraulic Cylinders Tandem Press Brake Equipment steel channel processing machine/street light pole CNC hydraulic tandem press brake machine and sheeet metal pres forming CNC sheet bending Machine Performace: the CNC press brake machine can bend long work piece in two press brake work together. the machien also can operate in individual Single and linkage action are available. Torque synchronization, electrical and hydraulic synchronization are guaranteed. Different CNC controllers to make multi-axis controlling are optional. Hydraulic / Mechanical ram, synchronised positive stop design, ram stroke controlled by precision mechanical nut depth stops built into each cylinder. Parallelism is ensured by torsion bar that can be easily adjusted by clutch system. Segmented heavy duty 86° offset top punch is segmented for return bend clearance, complete with European style quick release punch holder with an adjustable wedge clamping system for crowning.Intermediate clamp has safety key to stop punch dropping. Conveniently mounted control box on pendant for quick swivel and adjustments. Mono-block steel frame design, welded then machined to ensure minimal bed deflection under load Enclosed rear gate with micro safety switches complete with sliding rear door for easy access. European quick release style top punch and clamping system, allowing operator to change position of tooling to suit multiple requirements on complex applications. This feature ensures minimum down time, more productivity and results in reduced cost per finished product. Sliding steel fabricated sheet supports enabling a wide range of material sizes to be aligned and supported at the correct required height. This feature is achieved with a "T" slot machined down the total length of the die bed, sheet supports are also adjustable vertically to assist in supporting material with return bends folded. Adjustable sliding blocks control the machines beam to provide desirable open height distance to the (slow speed) mute bending point. CNC hydraulic tandem press brake Machine Feature: Tandem plate bending machine mode can be achieved by PSH or WE67K through the linkage unit.

ZSM-5 Zeolite , ZSM 5 Molecular Sieve With High Silica To Alumina Ratio Specifications Mole Ratio: 15-1000 Nominal Cation Form: Ammonium/Hydrogen JIULONG Products SiO2/Al2O3M , ole Ratio Nominal Cation Form Na2O Weight % Surface Area, m2/g JL 01 25 Sodium/Hydrogen 0.05 340 JL O2 30 Sodium/Hydrogen 0.05 340 JL 03 50 Sodium/Hydrogen 0.05 340 JL 04 80 Sodium/Hydrogen 0.05 340 JL 05 280 Sodium/Hydrogen 0.05 340 Na2O Weight %: 0.05 Surface Area, m2/g: 340 Description: ZSM-5 zeolite properties Thermal stability High thermal stability of ZSM-5 zeolite. This is caused by a skeleton in a stable five-membered ring structure and a high silica to alumina ratio. For example, the sample calcined at 850 ℃ After 2 hours, the crystal structure unchanged. Even can withstand high temperature of 1100 ℃. So far, ZSM-5 zeolites are known to one of the highest qualitative hot temperature. Therefore, it is used in high-temperature process is particularly suitable. For example, use it as a hydrocarbon cracking catalyst, regeneration of the catalyst can withstand passage of time. Acid resistance ZSM-5 zeolite has good acid resistance, it is resistant to various acids except hydrofluoric acid. Steam stability Wang, IKai other studies have shown that when other zeolites by steam and hot water, and their general structure is destroyed, leading to irreversible deactivation. The Mobil company with ZSM-5 as the conversion of methanol (water is one of the major product) catalyst. This suggests that ZSM-5 to water vapor with good stability. 540 ℃ lower partial pressure of 22mmHg steaming column and HY zeolite HZSM-5 after 24 hours, a crystallinity of HZSM-5 and about 70 percent of fresh catalyst, but under the same conditions, HY zeolite skeleton almost completely damage. Hydrophobic ZSM-5 having a high silica to alumina ratio, the smaller the surface charge density. The water molecule is polar, so you will not ZSM-5 is adsorbed. Although water molecules smaller than the diameter of n-hexane, but the amount of adsorption of n-hexane ZSM-5 is generally greater than water. Easy to coke ZSM-5 V-shaped aperture effective, pore size and bending, preventing a large condensate formation and accumulation. Meanwhile, ZSM-5 framework is no greater than the bore of the cavity (cage) exist, so limiting the formation of large molecules from the secondary condensation reactions. So that the possibility of ZSM-5 catalyst coke is reduced. ZSM-5 for an alkyl aromatics into the tunnel barrier is formed, and thus the reaction process it can not continue to react in smaller pores, the final condensation formed coke. ZSM-5 so much slower than the rate of coke deposition and Y-type mordenite, difference of almost two orders of magnitude. Capacity of ZSM-5 zeolite carbon content is higher. Excellent shape-selective selectivity Zeolite molecular sieve as catalyst, only smaller than the hole crystal molecules can catalyze the reaction out of control pore size crystalline zeolite suffering zeolite catalyst size and shape of reactant and product molecules showed great selectivity. Pore ​​system of ZSM-5 zeolite having a 10-MR constituted medium size orifice diameter, it has a good shape-selective selectivity.
