Rubber antioxidants passed the provincial-level scientific and technological achievement appraisal in Shandong
The rubber antioxidant H-TMQ and S-TMQ synthetic technology and industrialization projects undertaken by Shandong Kailei Shengao, a wholly-owned company of Jiangsu Shengao Chemical Technology Co., Ltd., passed provincial-level scientific and technological achievement appraisal in Jinan, Shandong Province. An expert group consisting of academician Fei Weiyang of the Chinese Academy of Sciences believes that the project has achieved significant technology in the reaction mechanism, process route selection, catalyst screening, detection technology and standards, application testing, reactor and separation equipment development of rubber antioxidant TMQ. Breakthroughs, innovations in a number of technologies, the overall process to achieve clean production requirements. Compared with traditional processes, the amount of new-generation process wastewater can be reduced by more than 90%, and the economic and social benefits are significant, reaching the international advanced level. At present, the results also apply for domestic and international patents. Experts also suggested that Jiangsu Shengao further strengthen the application research of high-content TMQ products, expand the scope of application of the product, and early develop a new catalyst without wastewater generated in the entire process route. What are Pipe Fusion Machines? and How do Butt Fusion Welding Machines work? Butt Fusion/ Heat Fusion is mainly for welding of plastic pipes and fittings made of HDPE, PP, PVDF. Pipe Thermofusion Machines are used in the construction, mining, oil and gas, water and sewerage industries etc,which are also called Field Butt Welding Machines. HDPE Pipe Butt fusion welding is a type of hot plate welding for thermoplastic pipes,Butt-fusion is a sensitive process, which is why all fusion parameters have to be coordinated to create a homogenous joint with consistently high welding quality. The butt welding machines used to weld PE pipes have controls to ensure the welding parameters are strictly adhered to. The following parameters are controlled:
♦changeover time
For Yuda RDH series Hydraulic Butt Fusion Machines, you can choose data logger to control these welding parameters. For Yuda RDH-A Series CNC Poly Pipe Butt Welding Machine, The CNC Welding system control these welding factors itself. Recently DVS2207 and ISO21307 welding standards input in data logger or cnc control system already.
