Online continuous detecting device of butylbenzene rubber reaction converting rate and calculating method thereof

Abstract

The invention discloses an online continuous detecting device of a butylbenzene rubber reaction converting rate. A section of vertical measuring pipe is arranged on an outlet material pipeline of a butylbenzene rubber device polymerization reactor by a pipe reducer and a rubber cement original pipeline; the large end of the pipe reducer is in seal communication with the vertical measuring pipe, and the small end of the pipe reducer is in seal communication with the rubber cement original pipeline; two pressure measuring points are extracted from the vertical measuring pipe, and a tiny differential pressure transmitter is used for measuring the pressure difference of the vertical pipeline between the two measuring points through which the rubber cement flows; a butylbenzene rubber cement temperature measuring point is arranged in the center in the vertical measuring pipe in the middle of the two pressure measuring points, and a temperature transmitter A is used for measuring rubber cement temperature; and an ambient temperature measuring point is arranged near the tiny differential pressure transmitter, and an ambient temperature transmitter B is used for measuring the ambient temperature. The three measured signal data are transmitted to a computer system for calculating. The invention adopts a conventional instrument and has the advantages of stable and reliable performance, less delay time, rapid response time, good closed loop control effect, convenient maintenance and long service life.

Description

technical field [0001] The invention relates to an online continuous detection device for the reaction conversion rate of styrene-butadiene rubber and a calculation method for the detection device. The utility model belongs to the parameter detection field of the rubber process industry. Background technique [0002] Styrene-butadiene rubber is the backbone product of the rubber industry. It is the largest variety of synthetic rubber with good comprehensive performance. It can be used instead of natural rubber in most occasions. It is mainly used in the tire industry, auto parts, hoses, tapes, rubber shoes, wires and cables. Other rubber products. [0003] Styrene butadiene rubber is made of butadiene and styrene monomers, using disproportionated abietic acid potassium soap and fatty acid soap as emulsifiers, adding activators, activators and regulators for low-temperature continuous emulsion polymerization to control the reaction conversion rate And glue Mooney, when the ...

AI Technical Summary

Problems solved by technology

It can be seen that the dry matter analysis method not only has a large workload, but also the time lag of the analysis results is too large, which cannot meet the requirements for real-time monitoring and control of the polymerization process of styrene-butadiene rubber.
