The invention further provides a preparation method for the molecular sieve / fiber compositematerial and various uses of the molecular sieve / fiber composite material. According to the molecular sieve / fiber composite material, the preparation method therefor and various uses of the molecularsieve / fiber composite material, the problem of molecular sieve / fiber composite materials that molecular sieves are gathered on surfaces of fibers is solved for the first time, the molecular sieve / fiber composite material prepared is bran-new and has relatively high strength, elasticity restorability and dimensional stability, and thus, the composite material is firm and durable. The molecular sieve / fiber composite material provided by the invention is simple in structure, low in cost, high in stability, high in performance repeatability and high in practical efficiency and can be applied to the fields of arresting bleeding, facial beautification, deodorization, sterilization, water purification, air purification and antiradiation.

The invention relates to a mould structure. In order to solve the technical problem that a mould for manufacturing a rubber part provided with two flanges is low in efficiency at present, the invention provides a mould which is reasonable in structure and easy to take out a part. The mould comprises a round upper die, a round lower die and a round middle die, wherein the upper die is matched with the middle die and the middle die is matched with the lower die through conical surfaces so that the upper die and the middle die are superimposed together and the middle die and the lower die are superimposed together; a stabilizing mail hole is formed in each of the upper die and the lower die; the upper die is connected with the lower die through stabilizing nails; a mandrel hole is formed in each of the upper die and the lower die; a mandrel penetrates through the mandrel hole of the upper die, an inner cavity of the middle die and the mandrel hole of the lower die; and a rubber part die cavity is formed among the upper die, the middle die and the lower die. The mould is characterized in that the middle die is longitudinally divided into a left part and a right part, and the left part and the right part are locked through a clamping ring after being closed up. The mould is simple in structure and low in cost, and has very high production efficiency and practical efficiency.

The invention provides a rotary type two-end heat-sealing die. A top-end heat-sealing device and a bottom-end heat-sealing device are separately arranged on an adjusting device through a rotating device; and the top-end heat-sealing device and the bottom-end heat-sealing device comprise heat-sealing disks, film-sealing heaters and pressure sensors, the heat sealing disks are connected with a positioning guide device, the film-sealing heaters are arranged on the heat-sealing disks, the pressure sensors are arranged on the heat sealing disks, and the pressure sensors are used for detecting whether the top-end heat-sealing device and the bottom-end heat-sealing device are in contact with articles to be heat-sealed or not. The upper end and lower end of the articles to be heat-sealed can be heat-sealed at the same time, so that the heat-sealing efficiency is improved, the pressure sensors are arranged on the heat-sealing device, the distance between the heat-sealing device and the articlesto be heat-sealed can be better controlled, the purpose of effective operation can be achieved for each heat-sealing, and the heat-sealing quality is improved.

The invention belongs to the field of gas separation engineering, and in particular relates to a proton-electron mixed conductor hydrogen permeable membrane, a preparation method thereof and a hydrogen permeable membrane reactor. Using polybenzimidazole, electronic conductor, and triglycidyl isocyanurate as raw materials, the electronic conductor is graphite or graphene, and dimethylacetamide is used as the solvent. After the raw materials and the solvent are mixed and dissolved, PBI / electronic conductor is prepared. / TGIC cross-linked composite film; then soaked in concentrated phosphoric acid or phosphate solution to obtain PBI / electronic conductor / TGIC / H 3 PO 4 Cross-linked composite membrane; then brush-coat Pt, Pd or Ag catalyst on the surface to obtain a proton-electron mixed conductor hydrogen permeable membrane. High hydrogen permeation rate, high mechanical strength, strong oxidation resistance, suitable for medium and low temperature environments, good thermal, chemical stability and oxidation resistance and other advantages; the invention also provides its preparation method with mild conditions and low cost ; The hydrogen permeable membrane can construct a high-efficiency medium and low temperature hydrogen permeable membrane reactor.

The invention relates to a fuel for burning. A solid charcoal for burning is made of bamboo sawdust, wood sawdust, or the mixture of both bamboo sawdust and wood sawdust. The sources of raw materials in the invention are wide and comprises waste of the wood sawdust and the bamboo sawdust, etc., reclaimed from the factories. The waste is effectively processed into solid core barbecue, the shape of which is the same as that of pure bamboo or solid charcoal. Since the components are pure, the charcoal has no smoke when being burned. The burning time of the charcoal is equal to that of the pure bamboo or solid charcoal. Compared with the composite charcoal, the similar products can extend the burning time for 1-1.5 hours, with small size and low cost. The components are made of natural fuels, without others. The product is with high quantity of heat, little ash and is not easy to be broken off when burning and poking the charcoal. The practicality is high. The invention has a simple technology and can control the performance of the product most effectively. The product can be comparable with the pure natural raw carbon.
