In recent days, the research team headed by Prof. Kong Qingchi of the China University of Fuels (East China) has successfully manufactured a new brominated triazine (tris(tribromobenzene-oxygen-based)-cyanurate) production process. However, in the existing technologies, tribromophenol, cyanuric chloride, and sodium hydrogen oxyhydroxide are used as the raw materials, because tribromophenol has the properties of water absorption and sublimation, and is difficult to dry. Therefore, a large amount of loss in the drying process results in the production of tribromophenol. Also larger. This technology is considered suitable and uses phenol to directly combine tris(tribromobenzene-oxygen-based)-cyanurate to prevent the synthesis, high purification, and drying of tribromophenol. The entire synthesis process is carried out in a reaction vessel. It eliminates the need for high purification, clutching, and drying of the mid- and mid-waist products, simplifying the process and reducing energy consumption.
In view of the insufficient existing technology, this technology is based on the process of first synthesizing tris(phenoxy-based)-trimeric cyanate, followed by bromination to synthesize tris(tribromobenzene-oxygen-based)-trimeric-isocyanate. Dissolve phenol in chlorobenzene solvent, then participate in anhydrous aluminum trichloride as a reagent, and then participate in cyanuric chloride, so that cyanuric chloride reacts with phenol to synthesize tris(phenoxy-based)-cyanurate, Reducing temperature and participating in water, using bromine as brominating agent, brominating, rinsing, distilling, forming crystals, centrifugal clutching, drying and other processes to obtain tris(tribromophenoxy-oxygen-based)-cyanuric ester finished product, preventing The tribromophenol synthesis, high purification, drying and other issues, the response in a reaction kettle implementation, eliminating the need for high purity purification, clutch, drying and other treatment, to simplify the process and reduce energy consumption.
Tris(tribromobenzene-oxygen-based)-trimeric-isocyanate is an excellent flame retardant and has excellent flame-retardant properties. Many researches on its synthetic methods have been made in and out of the country.

REASONS TO MODERNIZE YOUR ELEVATOR CONTROLS:
- You are experiencing higher repair costs related to controls
- Inefficient, poor reliability and operation
- Public safety considerations
- Long customer/tenant wait times
- Increased shutdowns and entrapments
- Landing and leveling problems
- Poor ride quality
- Decrease energy costs
- Serviceability/Proprietary Controls
-
Obsolescence
CEP Elevator Products specializes in custom elevator control modernization, ranging from simple updating of controls, cab and hall fixtures, to extensive replacement of all your existing elevator equipment. Elevator modernizations keep older buildings competitive with newer buildings, and typically provide a good financial return on your building as well as improving your elevators safety, reliability and performance. Depending on the age and condition of your elevator equipment, the extent of the modernization may vary. We can provide you with a free survey of your current equipment, and provide detailed information regarding the range of options for your upgrade. In addition to increasing the reliability and performance of your elevator, We will bring your elevator equipment up to current codes.
We only uses the best available equipment when performing modernizations. All modernizations begin with non-proprietary control systems and equipment which will enable you to use any qualified elevator service company of your choice to maintain your equipment in the future. Many large, international companies will only install their own proprietary controls and equipment which make it virtually impossible for building owners to change service companies down the road, regardless of the quality of service. This not only locks the building owner to one service company for the life of the equipment, it can also be costly in higher repair and maintenance costs.
After performing modernizations for over two decades, We have the experience and expertise to select the best individual components for your elevator. Many companies try to save money by cutting corners and using lower quality components; however we believe that the slightly higher price of the best components is well worth the cost to ensure that you not only get the look you expect, but also the performance and reliability for many years to come.
