On May 6, 2021, the Long March 5B carrier rocket took off for the first time, successfully sending the new-generation manned spacecraft test ship and the cargo return cabin test cabin into the scheduled orbit, and the curtain on the construction of the Chinese space station was also opened.
In this rocket, the polyetheretherketone/PEEK parts supplied by JSJH High Performance Engineering Plastics Technology Corporation play an important role.
This type of high-thrust rocket engine needs a long-term and reliable zero lock when it is not working, so as not to cause the engine swing hose to be under long-term force and reduce the reliability of the engine.
The high-performance PEEK parts supplied by JSJH have achieved high-reliability zero locking performance for the booster servo mechanism, and helped the Long March 5B launch vehicle successfully complete its mission.
As the resin material at the top of the pyramid, PEEK has the advantages of fatigue resistance, high temperature resistance, and light weight, so it is used on the Long March 5B launch vehicle. This is called "the most promising material in the 21st century" by the engineering community. It also has the advantages of hydrolysis resistance, radiation resistance, and self-lubrication. The use of PEEK can also make assembly faster, improve reliability, and reduce operating and manufacturing costs…
With good comprehensive performance, PEEK can replace traditional materials such as metals and ceramics in many special fields. It is one of the most popular new polymer materials today. It is mainly used in aerospace, automotive industry, electronic and electrical, medical machinery and other fields.
PEEK is also an excellent material for the production of medical implant consumables. It has the advantages of excellent X-ray transmission, light weight, wear resistance, corrosion resistance, and strong biocompatibility. JSJH has gradually expanded the application fields of spinal joints, trauma, sports medicine and other small segments.
PEEK has excellent compatibility with the human body. It entered the medical device industry in the late 1990s and has been widely used clinically. Its application prospects in the medical field are immeasurable.
In this field, orthopedic trauma demand is the field of JSJH's larger customers.
The first and second types of PEEK medical devices for surgery are currently being produced by the company. JSJH also focused on three types of equipment. The third type of equipment uses implantable PEEK, which is used in cranial repair, spinal incision and so on. The realization of implant-grade PEEK must first realize the supply of high-purity raw materials.
The layout from PEEK parts to PEEK plates, rods, tubes, and PEEK aggregation is actually equivalent to opening up the industrial chain, which can form a cost advantage; and after opening up the industrial chain, it brings another advantage, which can be controlled by The PEEK polymer ring meets the customized requirements of different customers for PEEK.
At present, JSJH's customer base covers more than ten industries, including: automobiles, electronic semiconductors, textile printing and dyeing, chemicals, machinery, 5G and electronic cigarettes. The largest proportion of sales comes from the three major areas of medical equipment, electronic semiconductors and aerospace.
Each industry has different requirements for the supply of PEEK. JSJH has established corresponding subsidiaries for different application fields. For the medical device industry, JSJH established JSJH Medical Technology Co., Ltd., with more than 120 people specializing in the medical device industry. PEEK parts.
Aiming at the aerospace field, it has joined hands with Donghua University to establish a joint venture JSJH Aerospace Composite Technology Co., Ltd. to jointly develop a continuous CF/PEEK thermoplastic prepreg composite project.
In terms of quality, the gap between the PEEK materials developed by JSJH and the leading PEEK competitors in Europe and the United States is gradually narrowing. In terms of PEEK resin, the basic properties such as mechanics, temperature resistance, color and appearance are not much different from those of Europe and the United States, and 80%-90% can be replaced.
