Abstract
The invention discloses a preparation method of a film containing polytetrafluoroethylene, which comprises the following steps: 1. selecting high-grade large-gold (M18) powder and pressing the powder into a rough blank; 2. putting the semi-finished rough blank into a baking oven, heating and sintering; 3. turning the sintered rough blank into a film with set thickness; and 4. cutting according to a width required by a customer. The invention has stronger tensile strength, good wear-resisting property and long service life.
Description
Technical field
The present invention relates to a kind of manufacture method that has polytetrafluoroethylene film, especially be applied to the manufacture method of military project, electronics, chemical industry, machinery, medical medicine industry conveyer belt.
Background technology
Traditional width has only 300mm wide in carrying industry at present, and 500mm is wide at most.Inconvenient operation like this, service life is short, and maintenance is also inconvenient.
Summary of the invention
The invention provides a kind of manufacture method that has polytetrafluoroethylene film, it not only has stronger hot strength, and anti-wear performance is good, and long service life.
The present invention has adopted following technical scheme: a kind of manufacture method of polytetrafluoroethylene film, and it may further comprise the steps: the first step, select for use high-quality Da Jin (M18) powder to be pressed into blank; In second step, the semi-finished product blank is put into the baking oven sintering of heating; In the 3rd step, burned blank vehicle is whittled into the film of formulating thickness; The 4th step is by the width cutting of customer requirement cutting.
Step 2 of the present invention is a sintering in baking oven, blank is placed on is incubated intensification in the baking oven repeatedly until 370 degrees centigrade of sintering maturations of maximum temperature.The step 3 turning process adopts the turning of high duty alloy cutter to replace traditional knot machine, thickness maximum allowance 0.01mm of control film of revolving.
The present invention has following beneficial effect: the present invention widens a width of cloth on the original basis that 300mm is wide or 500mm is wide, reach 1000mm.The user need be spliced a width of cloth is widened in the past, thereby the very possible overlapping uneven thickness that causes film influence the performance of product during splicing, used the film of wide the width of cloth, had improved the quality of product.The film elongation and the rate of curving are brought up to present 300% by original 100%, have more competitive advantage in the same industry.
The specific embodiment:
The present invention is a kind of manufacture method that has polytetrafluoroethylene film, and it may further comprise the steps: the first step, and select for use high-quality Da Jin (M18) powder to be pressed into blank; In second step, the semi-finished product blank is put into the baking oven sintering of heating; In the 3rd step, burned blank vehicle is whittled into the film of formulating thickness; The 4th step is by the width cutting of customer requirement cutting.
