Polyethylene products made from hexene-1 are superior to ordinary products in terms of tensile strength, right-angled tear strength, and other indicators. They are suitable for packaging films and agricultural films with long service life and high added value. However, due to foreign technology monopoly, China Petroleum's hexene-1 is all dependent on imports, and its price is high.
In order to enhance the competitiveness of polyethylene products in the market, the Petrochemical Institute has worked hard to explore and successfully develop a three-step hexene-1 synthesis process for the Qi-Na system and obtained national invention patents. In response to problems such as low product selectivity and high co-catalyst risk, the Petrochemical Institute started with catalyst innovation and completed high-selectivity hexene-1 pilot study, 100-ton pilot scale amplification, and process package development to form a world advanced system. Horizontal ethylene oligomerization of chromium catalysts for the synthesis of hexene-1 process technology. The main technical and economic indicators of this process technology have reached or surpassed the level of similar foreign technology.
Hexene-1 process technology development has been highly valued by China National Petroleum Corporation and supported by the planning and planning department, the science and technology management department, and the refining and chemical sector. In particular, in 2007, CNPC innovated the industrialization mechanism of scientific research achievements and adopted this as the first major scientific and technological project of the refining and chemical business of the Group, investing over 70 million yuan, and building a 5,000-ton hexene-1 industrial test facility in Daqing Petrochemical. Directly promote the industrialization of hexene-1 scientific research results. On September 25 this year, the Hexene-1 industrial test plant was successfully launched to produce hexene-1 with a purity of 99.53%.
The air mattress refers to a mattress that has strong flexibility and elasticity, and the inflationary volume becomes larger after inflating. Advantages: The elasticity of the inflatable bed is not easy to deform, and it is very comfortable to sleep. It feels like sleeping spring beds. It is easy to carry and move.
The quality of P&D inflatable air mattress is too good and uses peace of mind; folding is as large as the pillow, it is very easy to carry and move, without having to move home and throw away a mattress; when the guest comes, take it out of the drawer and charge up. Qi, there is a comfortable bed, and the guests walk away after walking; if your house is not spacious, then you can stand up and attach it against the wall during the day to give you a larger activity space; Like the spring bed, there is a bacteria inside, and it will be recessed after sleeping in the buttocks for a long time, and it will not be able to play. The inflatable bed will always be elastic.
