Abstract
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
The present invention relates to steel casting industry molding sand, core, particularly a kind of breather cord that is useful in resin, waterglass from hard sand, alicyclic organic ventilation effect in hard sand.
Background technology
In the steel casting industry, in casting technique,, reduced the qualification rate of product, caused waste product, substandard products, wasted more serious often owing to the gas in the foundry goods can not be discharged the quality that influences foundry goods.
Summary of the invention
Problem to be solved by this invention just provides a kind of plastics silk breather cord, can conveniently discharge the gas in the foundry goods, improves the quality of products and qualification rate, saves production cost.
In order to solve the problems of the technologies described above, the present invention adopts following technical scheme: a kind of plastics silk breather cord is characterized in that: cotton yarn by 35%～45% and 55%～65% plastics silk are formed.
Further, described plastics silk breather cord adopts the braiding of BL-168 braider to form.
Further, the diameter specifications of described plastics silk breather cord is 2mm, 4mm, 6mm, 8mm, 10mm or 12mm.
After adopting technique scheme, the present invention has following advantage: light weight, character are soft, arbitrarily bending; Have certain rigidity again, can not be crushed during filling moulding; Nontoxic pollution-free, environmental protection.
The specific embodiment
Embodiment one:
A kind of plastics silk breather cord, cotton yarn by 35% and 65% plastics silk are formed.
Embodiment two:
A kind of plastics silk breather cord, cotton yarn by 40% and 60% plastics silk are formed.
Embodiment three:
A kind of plastics silk breather cord, cotton yarn by 45% and 55% plastics silk are formed.
In the foregoing description, plastics silk breather cord adopts the braiding of BL-168 braider to form.The diameter specifications of plastics silk breather cord is 2mm, 4mm, 6mm, 8mm, 10mm or 12mm.
Except that above preferred embodiment, the present invention also has other embodiment, and those skilled in the art can make various changes and distortion according to the present invention, only otherwise break away from spirit of the present invention, all should belong to the defined scope of claims of the present invention.
