A method and a device for separately taking out a carton for packaging ceramic tiles belong to the field of packaging machinery and specifically relate to a method and a device for taking out a single carton. The method comprises the steps that: cartons are piled up in a carton storage bin the bottom of which is open, and the front ends of the cartons are bent downwards; then a carton separator is inserted between the bottom carton and an adjacent carton above the bottom carton; the carton separator is moved backwards to separate the bottom carton from the adjacent carton above the bottom carton; and the bottom carton drops down so as to completely separate a carton at a time. Most of the cartons in the carton storage bin are supported by carton brackets; the cartons which are not supported by the carton brackets are in level states due to own intensity; when a sucker sucks the bottom carton, the adjacent carton above the bottom carton does not bend along with the bottom carton, so that a gap with a certain included angle is generated between two adjacent cartons, and a separation head is smoothly inserted between two cartons to ensure that only one carton is sucked at a time.

The invention discloses a preparation method of an anti-pollution polysulfone / graphene oxide blended ultrafiltration membrane based on an ATRP (atom transfer radical polymerization method), which belongs to the technical field of ultrafiltration membranes. According to the method, graphene oxide after being grafted and modified is blended in a polysulfone solution, and the ultrafiltration membraneis prepared by virtue of NIPS.

The invention relates to a preparation method for a stretch wrap film, which belongs to the technical field of packaging materials. According to the method, carbon atoms in carbon nanotubes are hybridized by adopting SP2, so that the carbon nanotubes have high modulus and high strength, the carbon nanotubes have good mechanical properties, the carbon nanotubes with good flexibility can be stretched, and therefore the composite material which is prepared by adding the carbon nanotubes can show good strength, elasticity, fatigue resistance and isotropy. Because silica sol is adopted to wrap titanium dioxide and the carbon nanotubes in the method, titanium dioxide and the carbon nanotubes can be uniformly distributed and cannot be easily agglomerated; because the wrapping material is added, the silica sol which is a stable disperse system for silica colloid particles in water can act along with nanoscale titanium dioxide, so that the chemical property of the wrapping material is stable; moreover, as a continuous body with a spatial reticular structure, the silica sol has a large specific surface area to firmly adsorb the carbon nanotubes, and thereby the tensile strength of the stretch wrap film is effectively increased.
