The utility model discloses a quick release type no -adhesive tape corrugated paper express box relates to the technical field of corrugated paper box, including carton, the top of carton is connected with two aprons, the top of every apron is provided with magnetic attraction structure, and the magnetic attraction structure includes two connecting blocks that are installed on the top of carton, and the outside of every connecting block is connected with flexible pull plate, and the bottom of every flexible pull plate is all seted up with first installation slot, and the inside of every first installation slot all installs the first flexible magnet, and the top of every apron all sets up the slot mouth, and the inside of every slot mouth all sets up second installation slot, and the inside of every second installation slot all installs the second flexible magnet, and the outside of magnetic attraction structure is provided with the clamping structure, and the closure fixed of carton and apron is realized through magnetic attraction structure, replaces traditional adhesive tape sealing mode, reduces plastic adhesive tape use, and the magnetic attraction cooperation of first flexible magnet and second flexible magnet in magnetic attraction structure, and user can open the box through the flexible pull plate of separating magnet.

The present application relates to metal iron chip briquetting technical field, specifically relates to a kind of regenerative metal impurity removal briquetting equipment, including briquetting machine body, semicircle stop block, multiple flame heads and cross pushing mechanism, semicircle stop block can be transversely slidably installed in machine box, machine box is opened with semicircle stop block transversely sliding transverse guide sliding groove, longitudinal pressing plate is circular structure, the inside of semicircle stop block and transverse pressing plate is all provided with the semicircle groove that is attached with longitudinal pressing plate, the regenerative metal impurity removal briquetting equipment, by extruding large-area iron chip into cylindrical iron chip block, immediately carry out circumferential baking, can remove grease, coolant, plastic adhesive tape and paper towel in iron chip, and after extrusion is completed, immediately by longitudinal pressing plate longitudinal pushing, so that cylindrical iron chip block is compressed into compact structure, the whole compression process is rapid, and during compression process, since iron chip is heated, compression process is more labor-saving, and more compact after compression, save storage space.

The application relates to the technical field of plastic adhesive tapes, in particular to a completely biodegradable adhesive tape and a preparation method thereof; the completely biodegradable adhesive tape is composed of a completely biodegradable base material and a polycaprolactone-based completely biodegradable adhesive coated on the surface of the completely biodegradable base material; the completely biodegradable base material is made of the following components in mass fractions: 50-60 parts of polylactic acid, 40-50 parts of polybutylene succinate, 4-8 parts of a degradation synergistic master batch, 1-3 parts of polyglycolic acid powder and 1-3 parts of tributyl citrate; the polyglycolic acid accelerates the crystallization rate and the initial degradation rate, the degradation synergistic master batch improves the interface bonding of PLA / PBS, solves the defect of environmental tolerance and promotes synchronous degradation, and the combination of the two makes the prepared completely biodegradable adhesive tape have excellent mechanical properties, environmental stability and biodegradability.
