A high-gravity rotating bed device, including a motor, a rotor and a housing. The rotor and the motor are entirely arranged within the housing. A load-bearing plate is provided within the housing. The load-bearing plate divides the housing into a reaction chamber and a balance chamber. The motor is arranged within the balance chamber. A transmission shaft of the motor passes through the load-bearing plate and is fixedly connected to the rotor arranged within the reaction chamber. A gas inlet, a gas outlet, a liquid inlet and a liquid outlet are arranged on the housing. An externally communicating pipeline is arranged on the balance chamber. Also disclosed is an application of the present high-gravity rotating bed device under high-pressure conditions in operations such as mixing, transferring and reacting.

An on-line control and reaction process for pH adjustment and a control device for automatically adjusting pH value are provided. The process includes mixing a first enhancer and a second enhancer, optionally after diluting the first enhancer and/or the second enhancer with water, to form a mixture, setting a base pH value (δ1) and a target pH value (δ2), and adding pH adjuster into the mixture via a pH control unit and mixing to obtain a product with the target pH value. The pH control unit adjusts the adding of the pH adjuster by measuring or inputting certain parameters.

This rubber composition comprises a rubber wet master batch which uses a rubber latex solution and a carbon black (A)-containing slurry as raw materials, rubber, and carbon black (B), wherein the amount of the carbon black (A) in the rubber wet master batch is 1 to 35 parts by weight with respect to 100 parts by weight of the rubber component in the rubber wet master batch, and the total amount of the carbon black (A) and (B) in the rubber composition is 50 parts by weight or more with respect to 100 parts by weight of the total rubber component in the rubber composition. Accordingly, the present invention can provide: a rubber composition from which vulcanized rubber having excellent low heat generating properties and wear resistance can be obtained; and a method for producing the rubber composition.

The invention relates to a cross-linkable polymer including a base polymer including functional groups at least some of which have been reacted with a first organic molecule including a cross-linkable unit and with a second organic molecule capable of bonding to organic and/or inorganic substrates.
