In late June, Fushun Petrochemical's annual capacity of 800,000 tons of ethylene units in the ethylene compressor unit was successfully tested by a single turbine. This compressor unit is China's first self-developed largest ethylene compressor unit. The “China Heart” of Daiken successfully took off and marked the phased achievement of the localization project of Fushun Petrochemical’s one million-ton ethylene plant, filling the gap in the localization of China’s relevant major technical equipment, and making China become independent of the United States and Japan. One of the few million tons of ethylene compressors in the country.

The ethylene compressor unit is one of the key core devices in the ethylene plant and is called the "heart" of the ethylene plant. At present, in China's ethylene three-machine (crack gas compressor, ethylene compressor and propylene compressor), ethylene compressor has no overall machine design and manufacturing performance. This area has been monopolized by foreign countries. Most of the million-ton ethylene compressor units are imported equipment and they are expensive.

Fushun Petrochemical Co., Ltd. cooperated with Shengu Group to undertake the trial production and application of the first (set) domestically produced ethylene compressor, and determined the principle of maximizing the use of domestic technology and equipment manufacturing resources. On the one hand, it reduced the project's investment costs and enhanced the project's Market competitiveness, on the one hand, provides opportunities for the development of China's technological innovation and improvement of China's machinery manufacturing

Wood Door Sealant

A sealant is a substance used to stop fluids from passing through a seam or opening in a surface or material and is a type of mechanical seal. In building construction, sealants are sometimes synonymous with caulking and are also used to block the transfer of dust, sound and heat. Sealants can be weak or strong, flexible or rigid or temporary. Sealants are not adhesives, but some have adhesive properties and are called adhesive sealants or structural sealants.

Although not very strong, sealants have many properties. They seal the top structure to the substrate and are particularly effective during waterproofing by keeping moisture out of (or in) the components that use them. They provide thermal and acoustic insulation and can be used as a fire barrier. They may also have electrical properties. Sealant can also be used for simple smoothing or filling. They are usually required to perform several of these functions at a time.

A caulk sealant has three basic functions: it fills the gaps between two or more substrates; it forms a barrier through the physical properties of the sealant itself and its adhesion to the substrates. And it maintains hermetic properties over the life expectancy, usage conditions and environment. Sealants perform these functions through the correct formulation to achieve specific application and performance characteristics. However, aside from adhesives, there are few other functions that can replace the sealing process.
