On November 12, the Shanghai Stock Exchange released the announcement of the results of the 44th review meeting of the Science and Technology Innovation Board Listing Committee in 2019, and Fujian Saite New Materials Co.
, Ltd.
(hereinafter referred to as "Saite New Materials") was first approved
.
The main product of Saite New Materials is vacuum insulation board, which is a new type of high-efficiency, energy-saving and environmentally friendly insulation material produced by the principle of vacuum insulation.
The outside world does not know much about this industry
.
The traditional thermal insulation material is mainly polyurethane foam, which has simple processing process and low cost.
At present, it is also used as the main thermal insulation material in household refrigeration equipment such as refrigerators and freezers
.
At present, there is still no better alternative foaming technology for polyurethane foam, the substitution effect of vacuum insulation panels will be more obvious, and the market penetration rate will continue to increase
.
The vacuum insulation panel is mainly composed of three parts: core material, barrier film and adsorbent
.
Thanks to such materials and structures, the vacuum insulation panel has excellent thermal insulation performance, and the thermal conductivity is only 1/6 or even lower than that of traditional thermal insulation materials.
, The demand of household appliances (refrigerators, freezers) with high volume ratio requirements, as an important component of refrigerators, plays an important role in improving the energy efficiency of refrigerators and freezers
.
Subject to cost and other factors, vacuum insulation panels are currently mainly used in refrigerators with high energy efficiency requirements, high volume ratio requirements and high price refrigerators in the field of refrigerators and freezers.
The penetration rate in the global refrigerator freezer market is still low
.
According to the data of the industry research report released by the Pacific Securities Research Institute, the application of vacuum insulation panels in Japan, South Korea and European and American countries is relatively common, especially in large-volume air-cooled refrigerators in Japan and South Korea.
Insulation panels are widely used, among which Japan is affected by the energy crisis caused by the Fukushima nuclear leak in 2011 and the favorable domestic subsidy policy.
The vacuum insulation panel energy-saving refrigerator market develops rapidly, with an application ratio of 70%, and South Korea is also relatively high.
Europe is second, and the United States is less
.
Since the end of the 20th century, many international refrigerator and freezer manufacturers have set up production bases in China and transferred their main production capacity to China.
China has become the global refrigerator production center.
At present, the output of refrigerators and freezers accounts for more than 60% of the world's refrigerator output.
From 2010 to 2018 The output of domestic refrigerators and freezers in China fluctuates around 100 million units, of which the output of refrigerators is about 80 million units (of which about 50 million units are exported abroad, and about 30 million units are sold in the domestic market)
.
Referring to the current application penetration rate of vacuum insulation panels in mature markets such as Japan and South Korea, the average use of 2.
5 square meters of vacuum insulation panels for each refrigerator (unit price 100 yuan/m2) is calculated.
Only the potential market space of vacuum insulation panels in the domestic refrigerator appliance market It reached about 5.
25 billion yuan
.
In addition to refrigerators, freezers, etc.
, vacuum insulation panels can also be applied to many fields
.
Due to the combination of three methods of vacuum insulation, microporous insulation and multi-layer insulation, vacuum insulation panels can achieve ideal energy-saving and thermal insulation effects, and can be widely used in home appliances, construction, machinery, petroleum, electric power, metallurgy, transportation, warehousing, etc.
Industry, is a variety of buildings, industrial furnaces, boilers, heat exchangers, distillation towers, storage tanks, cold storage, flues, pipes, valves, fans, air conditioners, vehicles and ships, etc.
sound multifunctional material
.
The prospectus of Saite New Materials also revealed that the company will expand the technology formed in the process of research and development of nano-barrier film to different application fields such as medicine, food packaging, power lithium battery aluminum-plastic film, etc.
The technology accumulated by the company in vacuum insulation technology There is room for further development to help the company achieve research and development in vacuum glass
.
Process changes are also reducing the cost of VIP production
.
In the early days, the production of core materials mainly used the wet process, which was to beat glass microfiber cotton, and then copy and dry to form.
The process consumes a lot of energy and has no advantages in production cost and thermal conductivity
.
At present, the more advanced dry process has gradually become the mainstream, making the glass fiber basically single fiber, and the thickness of the single-layer glass fiber network is thinner.
Compared with the wet process, it has the advantages of lower production cost and lower thermal conductivity, and is more expensive.
The competitive advantage has accelerated the replacement process of traditional thermal insulation materials such as polyurethane
.
