[China Aluminum Industry Network] In recent years, aluminum substitute copper has become a hot spot in the air-conditioning and refrigeration industry. As the technology matures, aluminum alloy pipes and fittings have the cost savings of more than 30 yuan for air-conditioning and cooling pipe materials, corrosion protection, and extension. Heat exchange efficiency and other performance indicators, such as further improvement of competitive advantages, makes the application of aluminum substitute copper in the air conditioning field has become increasingly clear, and the current macroeconomic downturn, export Growth slowed down and domestic demand is insufficient, and the state encourages energy conservation and consumption reduction of the environment, This further stimulated the demand for air conditioning alloy aluminum piping products.
In 2016, the domestic heat exchanger industry will exceed 100 billion yuan, which undoubtedly provides a broader space for the heat exchanger industry. In the future, the domestic market demand will put forward higher requirements for product quality. The environmental protection and energy-saving aluminum plate-fin heat exchanger will also replace the traditional heat exchanger and become the focus of future development. The development prospect is very broad.
Edible salt, also called Table Salt or just salt, is a mineral, one of a very few mineral substance commonly
eaten by humans. There are different forms of Edible Salt: unrefined raw salt, refined salt, table salt or
iodized refined salt. It is a crystalline solid, white or light grey in colour, obtained from sea water or from
rock deposits. Sea Salt comes in fine or larger crystals. In nature, it includes not only Sodium Chloride,
but also other vital trace minerals. Edible rock salts may be slightly greyish in colour due to this mineral
content.
