Introduction and selection points of ship standard rubber flexible connection
Vulcanization or heat treatment of the parts after the electrochemical vulcanization, where the vulcanization or heat treatment of the ship standard rubber flexible connections in the electrochemical vulcanization according to two times, into the slot vulcanization 3 to 5 minutes to take out, will have loosened the welding slag and heat treatment oxide skin with a metal wire brush will brush it off, or knocked off with a small hammer, into the slot Ran vulcanization 3 to 5 minutes, can achieve better results. In the wire drawing skills just presented not long, this skill is applied in the cell phone shell planning and manufacturing, ship standard rubber soft connection wire drawing skills so that the ship standard rubber soft connection not only has a metal texture, and with this method of manufacturing ship standard rubber soft connection than other metal shell, not only the cost is more inexpensive, and has other ship standard rubber soft connection can not be compared to the use of life.
After vulcanization, apply heat treatment and pickling treatment of the exterior. Generally used for cold-rolled ship-standard rubber connections, industrial tanks, chemical industry installations, etc., thicker from 2.0MM-8.0MM. stainless steel tube processing plant and matte NO.2B cold-rolled after heat treatment, pickling, and then finish-rolled processing to make the appearance of moderate brightness. Because the appearance of lubrication, easy to re-grind, so that the appearance of more shiny. In the tensile test machine will pull the specimen to fracture, and then determine one or several mechanical properties, generally only determine the tensile strength, yield strength, elongation after break and section shortening rate.
Tensile test is the basic mechanical properties of the metal ship standard rubber flexible connection test method, simply all the metal ship standard rubber flexible connection, as long as the mechanical properties of the requirements, have rules of tensile test. Especially those shapes are not convenient for hardness test of the ship standard rubber flexible connections, tensile test has become the only mechanical properties testing methods. A ship standard rubber flexible connection with hardness tester according to the rules of the conditions slowly pressed into the specimen appearance, and then test the indentation or scale, so as to determine the size of the ship standard rubber flexible connection hardness.
Hardness test is a ship standard rubber flexible connection mechanical properties of the test is simple, agile, easy to implement the method. Hardness test is non-destructive, the ship standard rubber soft connection hardness value and tensile strength value between the approximate conversion relationship. Because the tensile test is not easy to test, and the conversion from hardness to strength is very convenient, and therefore people are increasingly only test the hardness of the rubber flexible connections and less test its strength. The ship's standard rubber soft connection to pass nondestructive testing, the need to suspend the inspection of the ship's standard rubber soft connection, requesting the ship's standard rubber soft connection smooth. According to the flow of liquid or gas corrosive selection of raw materials, according to the flow rate selection of pipe diameter, according to the wall pressure requirements to select the wall thickness.
