The invention discloses a plastic filament ventilation rope which consists of 35-45 percent of cotton yarn and 55-65 percent of plastic filament. The ventilation rope has the advantages of light weight and softness and can be optionally bent; the ventilation rope also has certain rigidity, thus the ventilation rope cannot be flattened while filling sand and modeling; the ventilation rope has no toxicity and pollution and is environmental friendly; and the ventilation rope is convenient to exhaust gas in a cast, improves the quality and the percent of pass of the product and saves the production cost.
Description
technical field [0001] The invention relates to mold sand and mold cores in the iron and steel foundry industry, in particular to a ventilation rope suitable for ventilation in resin, water glass no-bake sand and organic grease no-bake sand. Background technique [0002] In the iron and steel casting industry, the quality of the castings is often affected by the inability to discharge the gas in the castings during the casting process, which reduces the pass rate of the products, resulting in waste products, defective products, and serious waste. Contents of the invention [0003] The problem to be solved by the present invention is to provide a plastic wire ventilation rope, which can conveniently discharge the gas in the casting, improve product quality and pass rate, and save production cost. [0004] In order to solve the above-mentioned technical problems, the present invention adopts the following technical solutions: a plastic yarn ventilation rope, which is charact...
