China Drying Newsletter SBR1500HR, a high-speed rail-reduced styrene-butadiene rubber (SBR) 1500, jointly developed by the China Petroleum and Petrochemical Research Institute and Lanzhou Petrochemical Company, has recently achieved industrial trial production at the Lanzhou Petrochemical Synthetic Rubber Factory's 100,000-tonne/year facility, achieving full product performance. Indicator requirements.

With the continuous increase in the mileage of China’s railways, especially high-speed railways, the demand for shock-absorbing plates is also increasing rapidly. High-speed railway shock-absorbing plates are processed with styrene-butadiene rubber as the main material and laid between rails and sleepers. Vibration reduction and noise reduction. The domestic market for high-speed rail-reduced styrene-butadiene rubber products has a capacity of approximately 15,000 tons/year, of which Wuwei Rubber Products Factory of Lanzhou Railway Bureau accounts for approximately one-third of the market share of domestic railway rubber shock-absorbing plates. Lanhua SBR1500HR products are sold by the Northwest Chemical Sales Branch to Wuwei Rubber Products Factory of Lanzhou Railway Bureau for application tests.

Knife Gate Valves are usually used for pulp/paper and mining industries.

Knife Gate Valves are named for its sharp, knife-like disc, which could be used for cutting medium. The groove around the seat permits the gate to push particles aside and prevents clogging. When the valve is open, the flow cleans the groove. Seat is outside the flow area resulting in higher flow coefficient with minimum pressure drop.
