Description
Technical Field
The invention relates to a sewing device for a puffed plate, in particular to a sewing device for a puffed polytetrafluoroethylene large-size plate. The invention belongs to the field of manufacturing processes of expanded polytetrafluoroethylene sealing materials. The invention also relates to a method for sewing the bulking plate.
Background
The puffed board products are used for sealing and corrosion prevention in a large amount in the aircraft manufacturing process, particularly for sealing and corrosion prevention of parts needing to be frequently disassembled and maintained, such as a fuselage wing panel, a wing body fairing, a passenger-cargo cabin floor, a maintenance flap and the like, so that the manufacturing and maintenance time can be shortened, the comprehensive cost of the whole life cycle of the civil aircraft can be effectively reduced, and the puffed board is a key material of the civil aircraft.
Expanded Polytetrafluoroethylene (EPTFE) provides reliable surface protection, effective sealing and gap filling for civil aircraft, and has a density of about 0.4g/cm 3～0.8g/cm3, less than half that of conventional sealants. Meanwhile, compared with the traditional sealing materials (rubber and sealant), the material has a flexible structure, can be attached to complex shapes and irregular surfaces, has the advantages of no need of solidification, easy installation, easy disassembly, reusability and the like, and is widely applied to various airplane models.
The expanded polytetrafluoroethylene sheet is generally composed of an expanded polytetrafluoroethylene material body and a back adhesive, wherein the material body can realize the waterproof sealing function under the action of certain pressure, and the back adhesive is used for enabling the material body to be adhered to a part needing sealing.
The maximum production size of the expanded plate is 1500 multiplied by 3000mm at present, and the working efficiency is greatly reduced by sequentially coating the single expanded plate. Further, because of the coating apparatus, the front and rear ends of the expanded sheet in the length direction, for example, the lengths of 500mm each, are difficult to uniformly coat to meet the demand in the coating process, and thus the expanded sheet is worn in the length direction. In addition, the high-efficiency continuous coating of the back adhesive is difficult to realize at present due to the production length limitation of the expansion plate.
The common splicing modes in the market at present are adhesive tape connection and high-temperature welding. The adhesive tape used for connecting the adhesive tapes contains an adhesive, and when the puffing plate is subjected to subsequent medium resistance treatment, the adhesive can be partially dissolved in the treatment liquid to influence the puffing plate to obtain complete medium resistance.
Further, in the case of expanded polytetrafluoroethylene materials, when the heating temperature is higher than 400 ℃, the decomposition speed is gradually increased, and the decomposition product has a very small amount of highly toxic perfluoro isobutylene, so that the risk of poisoning exists in the high-temperature welding, on the other hand, expanded polytetrafluoroethylene needs to be sintered at a certain temperature and for a certain time to stabilize its structure so as to ensure the performance, and when the sintered expanded polytetrafluoroethylene is subjected to a high temperature again, the internal structure is partially changed, thereby affecting the performance of the material itself.
Accordingly, there remains a need for further improvements in existing apparatus and methods for splicing expanded panels.
