Knitted vamp with internal visual three-dimensional texture structure and manufacturing method of knitted vamp

The invention relates to the technical field of knitted vamps, in particular to a knitted vamp with an internal visual three-dimensional texture structure and a manufacturing method of the knitted vamp. The knitted vamp with the internal visual three-dimensional texture structure comprises a vamp body which is integrally woven, the vamp body comprises a surface layer, a three-dimensional texture structure layer and a bottom layer, the surface layer comprises a plurality of first yarns, the three-dimensional texture structure layer comprises a plurality of second yarns, and the bottom layer comprises a plurality of third yarns and a plurality of fourth yarns. By utilizing the characteristics of colored sand yarns, elastic yarns and transparent yarns and the matching effect of the colored sand yarns, the elastic yarns and the transparent yarns, the knitted vamp with the internal visual three-dimensional texture structure is integrally formed and knitted through a warp knitting machine, namely, the three-dimensional texture structure layer is knitted between the surface layer and the bottom layer of the knitted vamp and can be seen through the transparent yarns, and therefore, the vamp is good in air permeability, high in wear resistance, good in attractive effect and high in stereoscopic impression.

Preparation method for high-wear-resistance steel

InactiveCN113215479AStrong wear resistanceGood resistance to high temperature and corrosion
The invention provides a preparation method for high-wear-resistant steel. The preparation method comprises the steps that high-chromium cast iron is taken as a base material, an alloy is added into the base material for smelting to obtain a blank, a workpiece obtains high wear resistance, toughness and strength, the blank is finely rolled into a wear-resistant plate with a preset size, a grouting bag filled with a bonding solution is stuffed into each T-shaped groove, T-shaped strips on the wear-resistant plate are inserted from the open ends of the T-shaped grooves to extrude the grouting bags inwards till the T-shaped strips are inserted into the innermost part of the T-shaped grooves, coatings of the grouting bags are extruded to be broken, the bonding solutions inside the grouting bags flow out and fill a gap between the wear-resistant plate and a base plate to form a bonding layer, and countersunk bolts on the two sides of the base plate sequentially penetrate through countersunk holes and threaded holes so as to tighten the base plate and the T-shaped strips. The wear-resistant plate and the base plate are combined together through the T-shaped strips and the T-shaped grooves, are bonded through the bonding solutions, and the wear-resistant plate and the base plate are firmly bonded, and then are tightened and locked through the bolts, so that the firmness of the wear-resistant plate and the base plate is further guaranteed.

Manufacturing method of abrasion-resistant and anti-fracture trolley grate bar

The invention discloses a manufacturing method of an abrasion-resistant and anti-fracture trolley grate bar, and belongs to the technical field of furnace grate bars for sintering machine trolleys. The manufacturing method of the abrasion-resistant and anti-fracture trolley grate bar comprises the steps that low alloy cast steel and high chromium abrasion-resistant white mouth cast iron are separately poured into two electric furnaces to be smelted to control the temperature and time of the two electric furnaces, after smelted, low alloy cast molten steel is firstly poured into a casting mold,when the low alloy cast molten steel naturally cools to the critical temperature, namely, when the low alloy cast molten steel reaches a solid phase line, and then the high chromium abrasion-resistant white mouth casting molten iron is cast; and the weight ratio of the low alloy cast molten steel and the high chromium abrasion-resistant white mouth casting molten iron is controlled, and after thelow alloy cast molten steel and the high chromium abrasion-resistant white mouth casting molten iron cast, and then tempering, normalizing heat treatment are carried out. Compared with the prior art,the trolley grate bar prepared by the manufacturing method of the abrasion-resistant and anti-fracture trolley grate bar is tested in a 2#360m<2> sintering machine of a sintering plant for more thantwo years, the service life of the trolley grate bar is more than 4 times of the service life of an original monometallic high chromium cast iron alloy, no phenomenon of excessive burning loss and fracture collapse and scattered of the grate bar exists in more than two years of use, the sintering cost is greatly reduced, and the production efficiency is improved.

Silencing plastic pipe with high intensity

The invention discloses a silencing plastic pipe with high intensity. The silencing plastic pipe comprises a super-high density polyethylene outer pipe, a polyvinyl chloride resin layer and a foamed polyethylene inner pipe, wherein the polyvinyl chloride resin layer is arranged between the super-high density polyethylene outer pipe and the foamed polyethylene inner pipe; the polyvinyl chloride resin layer is connected with the super-high density polyethylene outer pipe through ABS plastic connection pieces; a reinforcing rib is arranged in the super-high density polyethylene outer pipe; a silencing cavity is formed between the foamed polyethylene inner pipe and the polyvinyl chloride resin layer; and a nylon and glass fiber mixing plastic piece is arranged in the silencing cavity. According to the silencing plastic pipe with high intensity, due to super-high density polyethylene and the silencing cavity, silencing and noise reduction can be well realized; furthermore, the super-high density polyethylene is high in wear resistance; by the adding of the reinforcing rib, the silencing plastic pipe is high in intensity; meanwhile, foamed polyethylene and polyvinyl chloride resin also have the silencing and noise reduction functions; a honeycomb structure in the polyvinyl chloride resin can well absorb sound; and the silencing plastic pipe is simple in structure and high in practicability.
