The calendered woman is half-finished through the contact of the city (4). (4) The thickness of the film is uniform, the distribution of the New Zealand is uniform, the size of the film is uniform, and the silk rate is uniform; ^276637 of the film product. The method:: ": The manufacturer of the axially-stretched microporous polytetrafluoroethylene film" ’” is intended to provide a thin tantalum product having a high permeability and a waterproof effect. At the door, "Kongfu's ancients, etc. 2: 2 and 4 are clear and simple, and they are created for the expected performance." When the novelty and progress of the case can be highlighted, the importance of the case is that the review committee can make progress. The technical means and the effect of the above-mentioned object==, the preferred embodiment is combined with the drawing [embodiment] 2, the characteristics of the Teflon bidirectional stretching film are analyzed, and the molecular weight of the weaving dragon Polytetraethylene is the main raw material and has been specially processed. It is a bidirectionally stretched film. The film is viewed by a high-magnification electron microscope. It is composed of very _fibers and nodes, which are caused by different temperature extension ratios. There will be a significant difference from the node, the larger times = the extension of the existing _ length of the surface, the 岐 will be linked to the fiber and the 之 歧 _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ The film of nano-fiber, and = the film is also the product or component that is urgently needed in various fields in the industry. This is a major profit in the process of observation and temperature control. 1276637 2 This - focus on simplifying the process and reducing For the purpose of improving the production capacity, the polytetra-ethylene thin film made by the invention can achieve the purpose of thickness, pore distribution, pore size and porosity, and has both a translucent and a high thief. For the purpose of the nature and the purpose of waterproofing, "reading the _7^" is the remainder of the "uniaxially-stretched microporous polytetrafluoroethylene" method, and the main components will be half. 10, the second stretch & 2 q, after shaping, and then through the winding process 4 to achieve the output of the finished film 50. Please cooperate with Guicai and Erqi, which is the reliance on the "manufacturing method of uniaxially stretched microporous polytetrafluoroethylene", and the equipment required for the process. The basic supplement is - semi-finished product i 〇, the finished product 1 〇 is defined as the slab-shaped polytetrazede-depressed film which can be said to be conventional, and the semi-finished product i Q is fed by the feed wheel. Work 0, input 'roller 11', 12', 13' into the extension process 2〇, and the extension process 20 includes a first stage extension 21, a second stage extension 2 2 and a predetermined type 23 'when the semi-finished product is ready The belt is conveyed to the first-drawing wheel 4 绖 roller 15 and the second stretching wheel 6 , and is defined as a first-stage extension 2 1 _, and the first-stage extension 21 is a roller-feeding Y, 12 4 3' and the first - stretching wheel 14, the second stretching wheel 6' speed difference 'material adjustment semi-finished product 1Q and fine fluoride B - extended film sheet when the amount of supply is applied to the longitudinal stretching force, The extension ratio of the first stage extension 2 8 1276637 1 to the extension amount before the extension of the first stage extension 21 is 1.5 times, when transported to the third stretch 17, with the fourth stretching wheel 8 between 4 'defined as the second stage extension 2 2, the second stage extends 2 2 j to the lateral (four) force, and in the second stage extends 2 2 or the month m The heating process of the predetermined type 23 is performed by the music-heating device 丄9', and the second stage of the heating process is carried out. The extension ratio of the extension amount to the extension of the first-stage extension 21 is 4 to 8 times. Because the extension is relatively large, it is necessary to pass the predetermined type 2 3 or the heating process to extend the extension of the second stage 2 2 and the elongation is higher, and the extension can be avoided by one extension. If the film is too large, the film itself is broken, the thickness, the pore diameter and the porosity are not uniform. The first stage extension 2, the second stage extension 22 and the predetermined type 23 are summarized as the extension process 2〇, and the extension process is 20 The total extension ratio is 6 to χ 2 times, and is transferred to the second heating device 20 through the extension process 2 ,, which is defined as the sizing 30, which is a thickness, a pore diameter and a porosity which are generated for the extension process 2 〇 a required or standard diaphragm, with a second The heating device 20 performs a heating process to achieve uniformity and fixation of the film thickness, pore size and porosity, thereby avoiding the phenomenon of film back-up (shrinkage), and finally by winding the roller 2 1 The winding speed at which the film is not broken is taken up by 4 〇 and is the output of the finished product 5 。.
