China's dimethyl carbonate and related products development and production base - Tangshan Chaoyang Chemical Plant achieved breakthroughs in the downstream products of dimethyl carbonate and the development of new processes. Diethyl carbonate, ethyl methyl carbonate, and diphenyl carbonate New products and processes such as esters and bis(trichloromethyl)carbonate (also known as triphosgene, solid phosgene) have been completed in small or medium-scale trials, and a 1,000-ton industrial production facility has been built.
Recently, the 1,000 tons transesterification process of diethyl carbonate produced by Chaoyang Chemical Factory in Tangshan City has been successfully developed and put into industrial trial production. The product quality of diethyl carbonate reaches more than 99.5% (capillary column gas chromatographic inspection). Cogeneration of ethyl methyl carbonate products. The annual production capacity of 3,000 tons of solid phosgene co-production of diethyl carbonate has been completed in the pilot test, and is expected to reach the scale of 3,000 tons/year by the end of 2003. Transesterification Diphenyl carbonate process has been completed a small test.
According to reports, diethyl carbonate is mainly used as a solvent for nitrocellulose, cellulose ethers, synthetic resins and natural resins, as well as intermediates for pyrethroids and phenobarbital. Used in the instrumentation industry for the manufacture of fixed paints for cathode coatings in electronic tubes. Methyl ethyl carbonate as a solvent for special flavors and intermediates can also be used as a lithium battery electrolyte solvent. Diphenyl carbonate is mainly used as a synthetic raw material for engineering plastics, polycarbonates, and poly-parabens, as well as a plasticizer and solvent for nitrocellulose. In addition, it can also be used as a solvent and a heating medium in chemical production. Bis(trichloromethyl)carbonate, also known as triphosgene and solid phosgene, is a new type of solid compound and has extremely wide applications in medicine, pesticides, dyes, organic synthesis, and polymer materials.

Galvanized Hexagonal Wire Netting
ŸGalvanized hexagonal wire mesh is also named Chicken wire netting, made of low carbon iron wire, galvanized or hot-dip zinc plated before or after weaving. Hexagonal Wire Netting is firm in structure and has flat surface. It is extensively used in INDUSTRIAL AND AGRICULTURAL CONSTRUCTUONS AS REINFORCEMNET AND FENCING. It is also used as Fence for Poultry Cage, Fishing, Garden and Children playground, etc.
Assortments Available for galvanized hexagonal wire according to processing:
Hexagonal wire, Electro Galvanized before Weaving
Hexagonal wire, Electro Galvanized After Weaving
Hexagonal wire, Hot Dipped Galvanized before Weaving

Note:
Twist Type:
1.) The above tolerance comply with standard EN10223-2:1997;
2.) Minimum Galvanization is only for typical wire diameter as stipulated
separately in the column for your reference; Also it is only for hot dipped
Galvanized Netting.
- ŸMesh from 25 mm are reverse-twisted,
-
Mesh smaller than 25 mm are twisted three
times.
For strengthening wire mesh purposes:
-
This wire mesh could has double edged Wires and the height
-
From
100 cm at the mesh from 25 mm are provided with an extra horizontal wire for
better stability.
- Mesh smaller than 25mm could also be made twisted five times, ensures that the product has higher resistance.
