Three factors can cause aging problem to silicone hose
With the development of science and technology and national economy in China, the automation require of all walks of life is getting higher and higher, the application of hydraulic technology is more and more extensive. People People are committed to improve the efficiency of various types of machinery and equipment. To get a higher working pressure, a compact layout and the development of a variety of purposes, which requires matching hydraulic hose both high pressure, low bending radius, suction and other characteristics, while requiring lightweight tube, which is the test hose manufacturing technology.
This paper introduces the formula design and production process of light hydraulic suction hose embedded in steel wire. (NBR) / styrene-butadiene rubber (SBR) (with the ratio of 80/20) as the main rubber, reinforcing material for the carbon black N550 / N774 (with the ratio of 35/35); middle rubber and The outer rubber was made of NBR / SBR (with a ratio of 40/60) and SBR / neoprene / chlorinated polyethylene rubber (20/30/50). Through the hose molding and curing equipment transformation, to achieve the automatic production of the hose. The finished product performance of the hose meets the Hydraulic hose SAE100R4 standard.
