Description
Technical Field
The utility model relates to a water treatment technical field, in particular to membrane distillation field specifically is a layer die mould microporous membrane manufacture equipment.
Background
The polytetrafluoroethylene has the advantages of temperature resistance, acid resistance, alkali resistance, multiple chemical corrosion resistance and extremely good chemical stability, and the surface tension of the polytetrafluoroethylene is (22-33) multiplied by 10-3N/m, excellent hydrophobicity makes it the first choice for membrane distillation and waterproof breathable materials.
The manufacturing process of the single-layer polytetrafluoroethylene microporous membrane mainly comprises the steps of mixing materials, blank making, extruding, rolling, longitudinal stretching, transverse stretching, curing and the like, and the microporous membrane with a crack hole structure is formed through stretching. The main reason is that the thickness of the middle area of the film is larger than that of the two side areas due to attenuation and hysteresis effects in the process of gradually transferring stress from the edge to the middle in the stretching process, so that the pore diameter of the middle area is small, the pore diameters of the two side areas are large, and the large pore diameter distribution is uneven.
The existing laminated microporous membrane manufacturing process and equipment are that upper and lower dies are pressed and heated for molding. The single-layer polytetrafluoroethylene film is thin and soft, is easy to deform and is easy to form wrinkles when being filled into a die; meanwhile, manual operation is required in the operation process, so that the forming is difficult, and the rejection rate is high; the manufactured single laminated polytetrafluoroethylene microporous membrane product has small area; the pressing time in a single die is long, continuous production cannot be realized, and the production efficiency is extremely low. More importantly, because of the non-adhesiveness of the polytetrafluoroethylene material, the existing laminated polytetrafluoroethylene microporous membrane has low peel strength between single-layer membranes, and the peel strength directly influences the service life and the use effect of the laminated microporous membrane.
The non-substrate laminated film has a much shorter life than the substrate laminated film due to water flow scouring and pressure variations during use. The production process of the laminated film requires higher temperature, thus easily causing the laminated film and the substrate not to be compounded at the same time. If a product compounded by a single-layer polytetrafluoroethylene microporous membrane and a base material is used, in the actual operation process, micropores on the single-layer membrane are gradually enlarged under the action of pressure, so that the rejection rate of the membrane is reduced, the durability is poor, the use effect is weakened, and the service life is shortened.
