The invention provides 3D science paper as well as a production method and production equipment thereof. The 3D science paper is prepared by soaking printing decorative paper serving as a raw material into glue with high transparency, wherein the glue comprises the following components in percentage by weight: 20-30% of polyurethane, 30-50% of acrylic resin, 1-3% of a cross-linking agent, 1-3% of a curing agent, 3-5% of a permeating agent, 1% of a flatting agent and the balance of water. The 3D science paper has an extremely good homochromatic effect, does not have chromatic aberration, is high in hardness, scratch-resistant, wear-proof and good in toughness, can be bent for 180 degrees without cracking, and is favorable for packaging. Moreover, the raw materials, aids, resin and the like in the production process of the product are water-soluble, so the 3D science paper is nontoxic and environmentally friendly.

The invention relates to an anti-wrinkle tidying method for a pure cotton fabric, sequentially comprising the following processes: shell fabric preparation, pre-limbering, resin padding, curing, rinsing, post-limbering and preshrinking. The method has the main technical characteristic that the padding formula used in the resin padding process comprises the following components by concentration: 80-120g / L of 2D resin, 80-100g / L of oxalaldehyde resin, 40g / L of 1,3-Dimethylurea, 40g / L of magnesium chloride activated by organic acid, 20-40g / L of brute-force protective agent, 1-2g / L of penetratingagent and the balance of water. The invention has reasonable design, and fully utilizes the advantages of two types of the resins and catalysts; the tidied pure cotton fabric has the characteristics of higher planeness, higher brute force, favorable abrasive resistance, lower formaldehyde content and the like; and the garment made of the tidied pure cotton fabric has the characteristics of comfortable wearing, beautiful appearance and strong durability.

The invention discloses a method for preparing regenerated corrugated paper base paper through rosin modified starch surface sizing. The corrugated paper base paper produced through the preparation method can be prepared into various corrugated paperboards and corrugated cartons through an adhesive, has good moisture-proof and waterproof effects, is long in water flow permeation time, has certain compressive strength, and is good in quality and not easy to break; recycled waste paper, cottonseed hulls and other substances serve as raw materials, so that the cost is low, energy conservation and consumption reduction are achieved, waste is utilized, wood pulp fiber resources are saved, and the process is convenient to control.

A combined cultivation method for water and soil conservation for sloping farmlands relates to cultivation methods for water and soil conservation and solves the problem that using the single cultivation technique for holding water is unsatisfactorily effective. The combined cultivation method includes: firstly, adjusting ridges of sloping farmlands on downward slopes and inclined slopes under ridge plowing adjusted into transverse slope ridges, and adopting contour farming and belt planting; secondly, building ridges, and planting protective plant belts on the ridges; thirdly, subsoiling forfarming; fourthly, performing furrow damming; and fifthly, performing no-tillage conservation tillage. Furrow subsoiling and furrow damming are technically combined and integrated according to soil and weather characteristics of a black soil area, so that water and soil loss is reduced or avoided for sloping farmlands to the greatest extent, water and soil are conserved, water utilization rate isincreased, and crop yield is increased evidently. By the method, soil saturation and infiltration speed ratio is increased by 24.1% in processing treatment, water utilization rate is increased by more than 15%, crop yield is 30kg per mu, and 100 Yuan per mu is increased..

The invention discloses a high-content grading fiber recycling aggregate concrete bulletproof explosion-proof brick, which is prepared from the following materials by mass: 16.30% of steel fibers, 0.04% of polypropylene fibers, 18.00-19.00% of cement, 5.40-5.60% of water, 2% of fly ash, 2% of slag powder, 2.60-3.00% of silica fume, 15.50-16.50% of sand, 36.00-37.00% of gravel, and 0.36% of an efficient water reducing agent. According to the present invention, the high-content grading fiber recycling aggregate concrete bulletproof explosion-proof brick has excellent compressive resistance, excellent tensile resistance, excellent bending resistance and excellent impact toughness compared to the clay bricks and the ordinary cement bricks, and is the novel high-performance composite material brick integrating high strength, bullet resistance, impact resistance, weight loading, bearing, wear resistance, and environment protection; and the purposes of resource saving and effective arable land and environment protection are achieved.

The invention discloses a method for counter-slope surface soil thickness increasing,permeation increasing and soil preparing of slope croplands, and relates to a method for permeation increasing and soil preparing of slope croplands. The method aims at solving the technical problems that at present, through a method for preventing and controlling water and soil loss of slope croplands, the height equality is hard to achieve, the occupied cultivation area is large, surface soil layers are disorganized, and the output reduction is caused. The method includes the steps of conducting shoveling in the direction opposite to the water running direction of a furrow and upwards pushing topsoil to form an inner channel, digging a groove in the pit bottom of the inner channel, filling the groove with a mixture of straw, fine sand and topsoil, placing deep soil dug out of a water storage permeation increasing groove on the lower portion in the water running direction of the furrow, and conducting backfill on the surface of the inner channel and the surface of a counter-slope surface soil ridge so that the bottom of the inner channel can be located on the same horizontal line. The method has the advantages that the rainfall water level can be reduced, the water and soil conservation effect is improved, the soil and nutrient loss of slope cropland surface layers is reduced, the ridge directions of the slope croplands are not changed, no land area is occupied, and the method is particularly suitable for slope croplands in black soil regions in the Northeast with vast territory, sparse population and shallow topsoil.
