The invention provides an artificial lentis, which contains anti-transforming growth factor beta 2 antibody membrane on the surface and can inhibit intercurrent post-cataract after cataract surgery, and also provides a the production method thereof. The production method includes the steps that: the artificial lentis is charged with positive electricity or negative electricity after the artificial lentis is cleaned, dried, and pretreated on the surface; the artificial lentis is soaked in a polyelectrolyte solution the charge of which is opposite to the surface charge of the artificial lentis for adsorbing, and rinsing the artificial lentis by deionized water, and drying the artificial lentis by nitrogen gas; the artificial lentis is soaked in a phosphate buffering solution of anti-transforming growth factor beta 2 antibody, the pH value of which is 4-10, and the carried charge of which is opposite to that of the polyelectrolyte, for adsorption; finally, the artificial lentis is rinsedby phosphate buffering solution, and the artificial lentis is dried by nitrogen gas; the alternating assembly steps are repeated. The artificial lentis of the invention can inhibit the transformationand differentiation as well as cyst membrane shrinkage of the lentis epithelial cells in a target way, and then interdicts the occurrence of the post-cataract, and has excellent biocompatibility. Theproduction method of the invention is scientific and simple, and can ensure the activity under a dry state and the safety and reliability during medical transplantation of the anti-transforming growth factor beta 2.

The invention relates to a high density glass fiber reinforced cement curved plate and a manufacturing method thereof. The curved plate comprises curve-shaped frames which have constant section and are made of fiberglass meshes, each frame is internally provided with two layers of glass long fibers with same curve shape, and coagulated layers which are composed of cement paste and glass fiber chopped strands and have same curve shape are respectively arranged between the two layers of curve-shaped glass long fibers, between the layers of curve-shaped glass long fibers and the upper and lower curve-shaped fiberglass meshes as well as the outer layers of the upper and lower curve-shaped fiberglass meshes. The manufacturing method has the following important steps: constructing a forming cavity prototype which is composed of a bottom prototype, a middle prototype and a top prototype, sizing and curing in a curve-shaped die cavity after semi-solidification, and completing the curve forming. The invention has the advantages of 1) breaking through the traditional view that cement products are necessary to combine with steel bars to constitute products, 2) breaking through the traditional view that the cement products are only flat-shaped, and 3) breaking through the traditional view that the prepared cement products only can be provided with straight surfaces.

Disclosed are a barrel-shaped integral concrete water storage tower tank and a preparation method thereof. The barrel-shaped integral concrete water storage tower tank is characterized in that a tank body, a tank top cover and a tank base are barrel-shaped semi-closed structures which are manufactured integrally, reinforcing ribs are arranged on the tank base, and a supporting base is integrally fixedly connected with or movably embedded at the bottoms of the reinforcing ribs. An integral precast method includes steps of material preparation, mold manufacture preparation and mold assembly, uniform concrete stirring, casting molding and curing and demoulding of finished products. The barrel-shaped integral concrete water storage tower tank and the preparation method thereof have the advantages that the integral strength of the tank body is high, service performances are excellent, processing is convenient, carrying and hoisting are easy, a manufacturing method is scientific, energy conservation and environmental protection are realized, labor and materials are saved, cost is low (the quantity of reinforced concrete is saved by about 30%), the barrel-shaped integral concrete water storage tower tank can be placed on a roof of the top of a building to be used as a domestic water reservoir or water storage tower tank and the like, and market competitiveness further can be strengthened.

The invention relates to manufacture method for 18k manganese-zinc ferrite magnetic powder magnetic core that includes the steps of mixing, solving, depositing, pre-firing, crushing, molding, and sintering. The manganese-zinc ferrite magnetic powder magnetic core has the feathers that magnetic permeability could reach to 18K, Curie temperature could reach to 120 degree centigrade, and the frequency could reach 100KHz. It could satisfy the request on communication, digital technology or network technology.

The invention relates to a composite high strength glass fiber reinforcing cement decorative, a fireproof and anti-explosive plate and a production line of the composite high strength glass fiber reinforcing cement decorative, waterproof and anti-explosive plate. The decorative, fireproof and anti-explosive plate comprises a chamber body structure formed by the enclosing of glass fiber gridding meshes, a metal layer, and a concrete layer with short glass fiber yarn embedded into the cement paste body, wherein a plurality of fins which are transversely arranged at a certain spacing and outwards punched to form outward openings are arranged on the metal layer plate body; and the metal layer is placed into the chamber body structure formed by the enclosing of the glass fiber gridding meshes. The invention also provides a production line of the decorative, fireproof and anti-explosive plate. The decorative, fireproof and anti-explosive plate and the production line have the following advantages: 1) an upper concrete layer and a lower concrete layer are organically combined through a plurality of fins which are transversely arranged at a certain spacing and outwards punched to form outward openings on the metal layer plate body, so that the impacting resistance is improved; and the combined part can be directly arranged on the external wall of a building structure as a fireproof and anti-explosive external wall decorative plate; and 2) a product is scientific and reasonable in manufacture method, continuous in production, high in efficiency and low in cost; and the plane of the product is varied along with the variation of a forming formwork; and the surface of the product is smooth, the deformation does not exist, and additional decoration is not required.

A Venturi exhaust air transfer device for purifying oil fume and a manufacturing method thereof belong to the technical field of machining. All parts are processed by casting molding, the manufacturing method is scientific and reasonable, and the manufacturing speed is fast. Compared with traditional milling, it can not only save processing materials, but also realize large-scale processing in the same process, reducing manufacturing costs. The components in the device are easy to assemble and disassemble quickly. The air inlet, throat and air outlet in the main structure of the device form a Venturi effect structure. The air speed of the air outlet is greater than the air speed of the air inlet, and negative pressure is generated through the venturi throat, and the fume is generated. Under the condition that the power of the machine suction motor is constant, the suction force of the oil fume is increased, and the energy saving effect is improved. In addition, the setting of the activated carbon cake further achieves the purpose of protecting the environment.

The invention relates to a wood-plastic composite floor and a manufacturing method thereof. The wood-plastic composite floor manufactured by the method comprises: from top to bottom, a surface coating layer, an upper surface board layer, an upper surface board modified layer, an intermediate layer, The lower panel modified layer and the lower panel layer are compositely composed. It can further alleviate the shortage of precious wood, and the surface of the carbonized surface is modified and then compounded with the intermediate layer, which improves the decoration of the surface of the wood-plastic composite material, and the veneer after carbonization treatment has good dimensional stability, small color difference, and wood. High utilization rate. The 18mm-thick wood-plastic composite floor of the present invention has a bending load of 1240N after being boiled (immersed)-freeze-dried, a dipping peeling rate of 0, and a wet friction coefficient of 0.7; it can save wood resources and have solid wood floors at the same time.
