Corrosion-resistant pressure differential transmitter housing and preparation method thereof

Abstract

The invention provides a corrosion-resistant pressure differential transmitter housing and a preparation method thereof and relates to the technical field of pressure differential transmitter production. The corrosion-resistant pressure differential transmitter housing is prepared, by weight, from the following raw materials of 55 to 65 parts of alumina, 25 to 35 parts of copper oxide, 12 to 16 parts of chromium trioxide, 16 to 20 parts of magnesium sulfate, 8 to 12 parts of chromium carbide, 8 to 12 parts of tungsten carbide, 14 to 18 parts of tributyl phosphite, 14 to 18 parts of triphenyl phosphite, 6 to 10 parts of N-benzylamine phenylenediamine, 6 to 10 parts of 2,4-diaminodiphenyl ether, 6 to 10 parts of 2-mercaptobenzothiazole , 6 to 10 parts of alkyl vinyl ester, 4 to 6 parts of coupling agents, 2 to 4 parts of toughening agents, 1 to 3 parts of dispersing agents, and 1 to 3 parts of antifoaming agents. The corrosion-resistant pressure differential transmitter housing has the advantages of overcoming the shortcomings of the prior art, effectively improving the corrosion resistance of the housing, preventing the housing from being in contact with various substances such as water for a long time and causing corrosion or even damage to thereby affect the measurement accuracy of internal components, providing high measurement accuracy and good use effect, effectively reducing the internal stress of the housing and preventing the housing from cracking, and guaranteeing superior performance and long service life.

Description

technical field [0001] The invention relates to the technical field of pressure difference transmitter production, in particular to a corrosion-resistant pressure difference transmitter shell and a preparation method thereof. Background technique [0002] The differential pressure transmitter is a device that converts pressure into pneumatic or electric signals for control and remote transmission. It can convert the physical pressure parameters such as gas and liquid felt by the load cell sensor into a standard electrical signal (such as 4~20mADC, etc.), to supply secondary instruments such as indicating alarms, recorders, regulators, etc. for measurement and indication and process regulation. Pressure transmitter is the most commonly used sensor in industrial practice. It is widely used in various industrial automatic control environments, involving water conservancy and hydropower, railway transportation, intelligent buildings, production automatic control, aerospace, mil...

Problems solved by technology

However, the quality of the current differential pressure transmitter shell is not high. When the shell is in contact with water and other substances for a long time, it is easy to be corroded or even damaged. This will easily affect the measurement accuracy of its internal components, and the use effect is not good. caused more trouble
