Plastics cover many industries in life, from airplanes and cars to garbage bags in life. The role of plastics has made it difficult for humans to find materials that can replace them. However, as the number of plastic products continues to increase, and the amount of waste plastics continues to increase, recycling and recycling of waste plastics is particularly important. At present, waste plastic recycling granulation is one of the main recycling methods in China. However, due to the imperfect recycling system, a large number of domestic recycled plastics enterprises rely on imported waste plastics for production. And as China officially proposed to the World Trade Organization (WTO) to adjust the garbage import regulations and reject high-contamination solid waste, mainly concentrated in four categories of waste plastics, vanadium slag, unsorted waste paper and waste textiles. . A large number of recycling enterprises that use imported waste plastics as raw materials for production will lose the source of raw materials for production. 2017 is a year of strict environmental protection, which makes plastics people stunned! After the "prohibition of waste", the import of waste plastics has basically been eliminated. Although it is currently only defined as a source of life, the industry is rumored that there is still the possibility of prohibiting industrial sources in the future, so the stability of raw materials has become a major problem for recycled plastics enterprises. For most domestic import traders, the promulgation of the ban will mean that they must re-plan their procurement channels, both from the procurement content and the source of the procurement, etc. will be a process of re-construction. If it is a purely imported trader who does not have a processing factory, this operation has been defined as non-standard. Strictly speaking, imported wool needs to have the production capacity matching its application quantity, and the customs and other executive departments are also strictly checking the waste plastics. Flow direction, so this type of enterprise must be transformed and upgraded. Some enterprises have taken precautions. When the ban was not promulgated, the conversion of raw materials from 100% to domestic production has been completed. Most enterprises are still undergoing transformation. The difficulty in recycling domestic wool has also made it more difficult to solve this problem. The tight domestic supply will cause difficulties in the production of product companies, which will start from the import of particles to supplement the shortage of supply. In the future, for imported recycled pellets, the source will be more turned to Japan, South Korea, Vietnam, Thailand, Malaysia and other countries. As for the traders of imported granules, many imported wool traders began to inquire about the import of granules, which led to the foreign granule suppliers to sit on the ground. At that time, the domestic environmental inspection was in full swing, the supply was tight, and some recycled plastics were also rising. In the process of completing the policy, although there is a ban on waste plastics, there is no obvious restriction on the recycled granules. Xiao Bian believes that this will be a major positive for imported granules.
A hydraulic valve is a device used to control the flow and pressure of hydraulic fluid in a hydraulic system. It is typically made up of a valve body, which contains the necessary ports and passages for fluid flow, and a valve spool or poppet, which is responsible for regulating the flow of fluid.
Hydraulic valves can be classified into various types based on their function and design. Some common types include:
1. Directional control valves: These valves control the direction of fluid flow in a hydraulic system. They typically have multiple ports and can be used to control the movement of hydraulic cylinders or motors.
2. Pressure control valves: These valves regulate the pressure of the hydraulic fluid in a system. They can be used to maintain a specific pressure level or limit the maximum pressure.
3. Flow control valves: These valves control the rate of fluid flow in a hydraulic system. They can be used to adjust the speed of hydraulic cylinders or control the flow to different actuators.
4. Check valves: These valves allow fluid flow in one direction while preventing it from flowing back in the opposite direction. They are commonly used to maintain pressure in hydraulic systems or prevent backflow.
Hydraulic valves are essential components in hydraulic systems, as they enable precise control and efficient operation. They are commonly used in various industries, including manufacturing, construction, agriculture, and automotive.
