Discussion on the production process of modified plastics and the industry of refrigeration compressor

Date:2018-03-08 Author: Click:

Since the 80s of last century, China's modified plastics industry has been initially developed with more than 20 years of development, and the main products are filled master batch, functional masterbatch and modified plastic special material. The improvement of the production process of the modified plastics also led to the development of the refrigeration compressor industry.

Refrigeration machine to shorten the modified plastic may consist of small and medium-sized refrigeration machine refrigeration compressor, the small and medium-sized refrigeration expansion machine is mainly used in the freezer (back and forth and rotary structure, Wu Yi frequency is the future development tendency and the refrigerator car (car) the type of screw machine is to shrink range) large and medium-sized refrigeration; shorten machine is mainly used in railway refrigerated trucks, refrigerated ships, refrigerated containers and cold storage, with reciprocating, screw type. Screw type expansion machine because of its appropriate lasting 24 hours of operation in common, as well as the use of low temperature in trivial technology from time to time travel, the performance and function of a selection. In the high temperature refrigeration system, piston type machine screw tightening machine began to gradually replace the traditional modified plastics has become the scale set.

The air conditioner industry statistics show that the air conditioning market in China increased at a high speed in 2004, with an increasing rate of 48%. The air conditioning industry in the real estate business premises, warehouse logistics, enlightenment 100 large public building construction and other initiatives, demand will continue strong, about 2005~2010 years, the central air conditioner sales of an average annual increase rate of about 10% ~ 20%. The screw compressor will therefore develop in place lost, air conditioning standard medium 30RT-500RT, screw machine has gradually replaced the contraction piston shortening machine.

The property foundation level increasingly strict, driven by the demand for plastic production of refrigeration with fiscal reform increased steadily. The proportion of refrigeration and refrigeration industry in the whole refrigeration industry is about 20%, which is far below the proportion of about 40% of the international mature market. The market of freezing and refrigerating industry is very strong, especially in the medium and low temperature refrigeration equipment in agriculture, fishery and animal husbandry. Compared with the prosperity of the country, the marine region is consistent with the cold storage, freezing, and logistics of agricultural, fishery, and animal husbandry and other agricultural and sideline products. The average growth rate of the decadent industrial refrigeration and refrigeration was about 20% to 25%, and the growth rate of the neutral estimate was between 10% and 20% in 2006-2010 years.

Screw type and short machine industry to provide competition with color screw system and short machine industry is a technology intensive industry, production of plastic devices relative to the complex, high precision machining products, and technology update is difficult, it is necessary for the enterprise's sustainable development strength and skills of reserves, also needs certain the theory of implicit teaching. The screw compressor manufacturers through the process of Wu Yi introduction, Wu Yi alone or independent research and development, improve the skills of content and performance of product quality, but its products with international standards in line with the elders, and noise, oil functions still have not gap.

Now, the center of compressor manufacturing in the world is gradually shifting to the land of China, and the major international austerity manufacturers have entered the Chinese market. The world's leading compressor production enterprise has a production base in China. The first compressor manufacturers are very seriously in Chinese, a leading international compressor production enterprises to enter the China reduce China's refrigeration compressor industry market competition, compressor international enterprises must run to catch up, the power of the world stand in an invincible position.
