This kind of catalyst which is also named sulfuric acid catalyst, and specially used to convert sulfur dioxide into sulfur trioxide in the process of sulfuric acid manufacturing. The catalyst is filled into each bed of the convertor. Generally speaking, the convertor equipment can be classified into two large systems. Double contact double absorption and single contact single absorption. We can supply mainly two large series catalyst as below. 1). Type S101 series of broad temperature catalyst The ignition temperature is 400â??. For continuous operation, the temperature should be in the range 420-620â??, which is suitable for each bed of converter for its high and stable activity. 2). Type S108 series of low temperature catalyst The ignition temperature is 380â?? and operating temperature 400-540â??, which suit for 1/3 top of the first bed to decrease inlet operating temperature, and 4th bed, 5th bed to improve equilibrium conversion and decrease gas emission. 3). Different catalyst shape is the reason to reduce catalyst bed pressure drops which translates directly into energy savings as a result of reduced blower power consumption. Reduced pressure drops also allow more dust to accumulate before pressure drops increase to the point where the plant must be shut down for catalyst screening. The catalyst shape must achieve all of the above without compromising on catalyst activity or mechanical strength. 4). The length of catalysts can be made according to the userâ??s requirement.

Product Introduction JPXC-1000 biased pole relay is an important component in interlocking equipment and the main equipment to ensure the safe operation of the system. The signal relay can control the switching of the turnout, lock and unlock the way, and control the opening and closing of the signal machine. Relays are widely used in railway signal technology, called signal relays, which are important components in railway signal technology. It plays an important role no matter as the core component of the relay signal system or as the interface component of the electronic or computer signal system. The reliability of the relay action directly affects the reliability and safety of the signal system. Product Usage The JPXC-1000 biased pole relay is designed to identify the polarity of the current in the signal circuit. In the signal circuit, it is used in the turnout indication circuit and the single-multiplex semi-automatic blocking circuit. Features 1. The relay adds a pole-biased magnet to the magnetic circuit, so that the armature is biased to the drop position by the permanent magnetic force. The pull-up of the armature is related to the polarity of the current in the coil. When the current through the coil is in the specified direction, the armature is pulled up, and when the direction of the current is opposite, the armature remains stationary. It only has a stable state, that is, after the armature is sucked up by electromagnetic force, it will fall when the power is cut off, and it will always be in a falling positioning state. 2. The relay is a heavy spring force DC electromagnetic relay, which uses the principle of "constant gravity" to force the moving and closing contacts to open when the coil is powered off. 3. It adopts silver-silver cadmium oxide contact, which has the characteristics of strong anti-adhesion and low contact resistance. 4. The magnetic circuit adopts electromagnetic pure iron material with small residual magnetism, and installs the stop piece at the closed position of the armature and the iron core to ensure the minimum air gap of the magnetic circuit, prevent the magnetization of the ferromagnetic parts of the magnetic circuit, and ensure the reliable fall of the relay. 5. The relay contact system is composed of ordinary contacts, with 8 groups of ordinary moving on and moving off conversion contacts. 6. The rated voltage of the relay is DC 24V.

HPMC powder is a highly pure cotton cellulose as raw material, under alkaline conditions by special etherification and preparation.White or whitish powder. HPMC powder decreases with the decrease of methoxide content, increase of gel point, decrease of water solubility and decrease of surface activity. Description: Hebei Yibang Building Materials Co., Ltd.â??s hpmc powder can be dissolved in some organic solvents and water-organic solvent mixed solvents. It does not have gelling properties when heated. Hpmc powder is a kind of cotton and wood raw material that is non-toxic to humans. Hpmc powder is hygroscopic when dry, but stable. Its solution is stable at pH 3-11. As the temperature increases, the viscosity of the solution decreases. Heating and cooling can reversibly transform the Hpmc powder from a solution state to a gel state. According to different grades and concentrations, the gelation temperature is 50~90â??. Hpmc powder has anti-enzyme effect as an aqueous solution and maintains good viscosity stability during long-term storage. However, its aqueous solution is susceptible to microbial attack, so preservatives should be added during storage. When Hpmc powder is used as a thickener for eye drops, benzalkonium chloride is usually added as a preservative. Basic Info Model NO.

Air check Advantage Methyl Bromide Fumigation Monitor The PureAire Air check Advantage is a compact, extractive gas monitoring system that's ideal for continuously and remotely monitoring fumigation chambers and fruit storage areas where access may be limited or undesirable. Featuring a special pyrolizer and sample pump, this accurate methyl bromide gas monitor has been tested to provide ultra low 0.3ppm and lower detection of methyl bromide levels in the workplace. PureAire's continuous monitor eliminates the need to subject an employee into fumigation chambers to manually take colorimetric grab samples to determine if an area is safe to enter. The instrument's "smart" circuitry continuously monitors sensor cell status and sampling system performance. Continuous sensor cell operation is transmitted via 4-20mA signal to PureAire controllers, PLC's or remote alarm systems. Should a system error occur, the Air check Advantage outputs a signal to remote alarm/control systems to immediately alert control room personnel. The heart of the system is a smart renewable sensor cell linked to a compact pyrolizer. Sample is drawn through the pyrolizer where Methyl bromide is thermally decomposed and converted into another gas that is more easily detected electrochemically. Unlike competitive Methyl bromide detectors and colorimetric tubes which have interferences to humidity, temperature and moisture, the Air check sensor and electronics are unaffected by changes in environment. This stability provides true sub TLV measurement of methyl bromide in product storage areas without the need for conversion tables. Air check Advantage Methyl Bromide Fumigation Monitor Features * Detects Methyl Bromide at sub, (0.5ppm) TLV levels for Fumigation * Enhanced self-diagnostic capability decreases downtime and maintenance costs * Supervised sensor electronics continuously checks sensor and system status * Built-in user selectable local dual level alarms with relay output * Local digital display * 4-20 mA analog output * Low-cost renewable sensor

Product Introduction SF6 switch is a widely used high voltage electrical appliance in the power system. SF6 gas density relay is an important element used to monitor the variation of SF6 gas density in the SF6 switch body during operation. Its performance directly affects the operation safety of SF6 switch.Due to the infrequent operation of SF6 gas density relay in the field it is often found that the operation is not flexible and the contact contact is not good after a period of time and some of the temperature compensation performance of the density relay becomes worse. When the ambient temperature changes suddenly the SF6 density relay often misoperates.Therefore DL/T596-2005 "precautionary test regulations for power equipment" stipulates that each SF6 switch user should verify SF6 gas density relay regularly.From the perspective of actual operation it is necessary to carry out regular calibration of SF6 density relay and pressure gauge in field operation. The check pressure sensor with high precision and high speed A/D converter combining with the 32 bit high performance microprocessor can check the performance of A variety of SF6 gas density relay can accurately measure the movement of the signal when the current temperature pressure value arbitrary automatically when the environment temperature of 20 â?? conversion standard pressure and have A print store and U disk offload function at the same time the fault in the process of automatic identification test.Sf6 gas density relay calibrator is convenient to carry simple to operate high test accuracy strong stability and good reliability which reflects the characteristics of "intelligent" instrument.
