Description
Technical field
The present invention relates to a kind of film and split the technique that legal system makes PTFE sewing thread.
Background technology
Politef (Teflon or PTFE), is commonly called as " King ", is by tetrafluoro second
The macromolecular compound that alkene is aggregated, have excellent chemical stability, corrosion resistance,
Sealing, high lubrication non-stick, electrical insulating property and good aging resistance endurance.As engineering plastic
Material, can be made into polyfluortetraethylene pipe, rod, band, plate, thin film etc..PTFE is that thermoplasticity is moulded
Material, but it is difficult to process with the forming method of ordinary thermoplastics, its " difficult processing
Property " come from the mouldability that it is special, as big in the melted withered degree of PTFE, shear-sensitive, big
Contractility creep properties and low friction factor.
The manufacturing process of existing PTFE sewing thread is more complicated, uses machinery calendering, manually
Stretching, also exists the problems such as labor intensity is big, production efficiency is low, the even thickness of product difference,
Affecting using effect, the mode of production of half machinery, production efficiency is low.The film used in operation
Draft apparatus, complicated structure, it is the most convenient to use, and the labor intensity of workman is big, produces
Efficiency is low, and the film that drawing-off goes out is uneven；Film is used to split the structure ratio of draft apparatus in operation
More complicated, operation is loaded down with trivial details, and it is the most convenient to use, and the labor intensity of workman is big, and production efficiency is low,
The silk that shredding process is easily broken off and cuts out is uneven, and process is discontinuous, stitches PTFE
The uniformity of line, intensity and the qualification rate of threading causes and has a strong impact on.Existing PTFE sewing thread system
Make technique can not meet the needs of production.
