China Scratch Mat

The opener, mixing box, carding machine and netting machine must be grounded as a whole to eliminate or reduce the static electricity generated during fiber transfer, carding and netting.As we all know, PTFE fiber has high static electricity, low crimp, smooth fiber, poor cohesion, and high density. The control of uniformity is a very important indicator in the production of needle punched filter felt. Control of uniformity and surface density of needle-punched felt In the application of needle-punched filter felt, the uniformity directly affects its service life. Overcoming these difficulties involves the key technology for the production of 100% PTFE needle punched filter materials. It is very difficult to comb and lay such fiber. (2) Adjust the position of the inclined curtain of the carding machine and the conveying curtain of the web-laying machine, so that the wool net can be completely transferred, and reduce the problem of net breakage caused by the weight and small cohesive force of the PTFE fiber wool n Adjust the speed of each transfer point to solve the problem of the fleece being pulled off due to the small cohesive force between the fibers and the excessively fast transfer speed. In order to ensure the smooth carding and transfer of PTFE fibers, and reduce the abnormal net leakage and net breakage, some parts of the equipment must be modified and adjusted to solve the problems of carding, netting, and netting. Transform the distance between the reciprocating drive of the net-laying machine and the bottom curtain to be adjustable, so that the drop between the transfer points of the net-laying machine is adjustable, and control the different surface density of the wool net to be continuously and normally transferred, and solve the problem of The problem of network disconnection caused by self-heavy weight and small cohesive force between fibers during the laying process. The modification and adjustment of the equipment are as follows:  ,PTFE adhesive tape ...ادامه مطلب
