Studies have shown that nonylphenol has a negative impact on health and the environment

  

 On October 28, 2011, scientists from Sweden said that in the experiment of zebrafish, 4-nonylphenol (4-NP) affects the neuroendocrine system and has a certain effect on the spinal cord and muscle function. . The researchers concluded that the data showed that nonylphenol would permanently affect the development of zebrafish young children, and that their compounds would also cause some harm through signal transmission.
At the same time, a group of scientists in Japan have issued a reminder to test the genotoxicity of human cells, and must pay attention to nonylphenol polyethoxylates (NPEOs) and their genotoxicity.
The third group of researchers in Italy tested whether the concentration of nonylphenol in the environment would affect the adrenal gland. It was found that nonylphenol interferes with adrenal activity in the sputum.
Greenpeace, a non-governmental organization, has also launched an initiative to ensure that non-phenolic nonylphenol ethoxylates (NPEs) are no longer used in products. These chemicals are subsequently broken down into phenols (NP), a persistent toxic substance that interferes with thyroid hormones and is toxic even at lower levels.

Hydraulic Cylinder

The hydraulic cylinder is a hydraulic actuator that converts hydraulic energy into mechanical energy and does linear reciprocating motion (or oscillating motion). It has a simple structure and works reliably. When it is used to realize reciprocating motion, the deceleration device can be dispensed with, and there is no transmission clearance, and the movement is stable, so it is widely used in the hydraulic system of various machinery. The output force of the hydraulic cylinder is proportional to the effective area of the piston and the pressure difference between its two sides, and the hydraulic cylinder is basically composed of cylinder barrel and cylinder head, piston and piston rod, sealing device, buffer device and exhaust device.
