Embodiment 1

[0053] The present invention uses Teflon AF2400 as the material of the homogeneous non-porous polymer ultra-thin film layer 2, and Teflon AF2400 is a polymer with a high oxygen permeability or a high selectivity to oxygen permeation that obeys a dissolution-diffusion model. The highly asymmetric submicron polysulfone is used as the material of the porous ultra-thin film carrier layer 3 . The average pore size distribution characteristics of the highly asymmetric sub-micron polysulfone are as follows: 1. The highly asymmetric sub-micron polysulfone is used as a porous ultra-thin film carrier layer 3, which is the surface micro-dipped with Teflon AF2400 solution , that is, the surface in contact with the homogeneous non-porous polymer ultra-thin film layer 2, its average pore diameter is 0.05 micron, 2, the average pore diameter is 0.05 micron thickness is only 10 microns, 3, the average pore diameter of the outer surface is 5.0 Micron, 4. The total thickness is 120 microns, and...

Embodiment 2

[0063]The present invention uses Teflon AF2400 as the material of the homogeneous non-porous polymer ultra-thin film layer 2, and Teflon AF2400 is a polymer with high oxygen permeability or high selectivity to oxygen compliance (or applicable) dissolution-diffusion model. The polytetrafluoroethylene porous polymer is used as the porous ultra-thin film carrier layer 3-1 of the homogeneous non-porous polymer ultra-thin film layer 2, and then polyester non-woven fabric is used as the polytetrafluoroethylene porous polymer The supporting substrate 3-2. This composite porous ultra-thin film carrier layer 3 is made by laminating and bonding the polytetrafluoroethylene porous polymer and the polyester non-woven support substrate. The characteristics of the composite porous ultra-thin film carrier layer are as follows: 1. The porous ultra-thin film carrier layer 3 is made of two layers of porous polymer materials, 2. The first layer that contacts the homogeneous non-porous polymer fil...

Abstract

The invention discloses curtain coating micro dip coating continuous production equipment and a method of an ultrathin membrane polymer complex film, belonging to the technical field of chemical equipment and process. The technical scheme I is that the production equipment provided by the invention comprises a transmission system, a computer control system, a micro dip coating system, a drying system and a solvent recovery system; The technical scheme II is the curtain coating micro dip coating continuous production method of the ultrathin membrane polymer complex film provided by the invention. The equipment and the method provided by the invention have the advantages that the complex film is continuously automatically produced, the production efficiency is high, and the end product quality is good; the uniform and flawless complex film is produced, the temperature, resistance time and vacuum degree and the like of a vacuum drying oven are controlled, and the quality of the complex film is guaranteed; a solvent is recovered, the manufacturing cost is saved, meanwhile, the environmental pollution is stopped, and when output achieves a certain scale, the costs of the continuous production equipment and the method are lower than the batch processing costs.

Description

technical field [0001] The invention belongs to the technical field of chemical equipment and chemical technology, and in particular relates to a device for filtering or permeating air and capable of producing five anti-dust particles (including PM2.5), anti-virus, anti-bacteria, anti-pollutant, anti- Soot) and oxygen-enriched functions, the manufacturing equipment and preparation method of ultra-thin polymer composite membranes made of polymers with high oxygen permeability or highly selective permeation to oxygen complying with the dissolution-diffusion model. Background technique [0002] Air pollution produces smog in densely populated areas, especially in large and medium-sized cities, seriously threatening people's health and lives. The mechanism that haze weather produces is very complicated, and its chemical composition is also very complicated. These substances may cause cancer and other serious diseases. More importantly, viruses and germs can survive and reprodu...
