The dried fruit pieces of the present invention are less sticky and are readily separated from one another using ordinary gravity feed handling conditions.

The invention discloses a flower vat imitating travertine. The molding material is mainly composed of solid materials, blending solution and short fibers. The weight percentage of the solid materials: 30-45% rapid hardening sulfoaluminate cement, 65% fine river sand, 1-3% titanium dioxide, 1-3% yellow powder, 0.01-0.15% red powder; the weight percentage of the blended solution: 99-99.9% water, 0.01-0.1% polyacrylamide; The staple fibers described above: glass fibers with a length of 5 to 10 cm; the present invention also discloses a process for producing the above-mentioned imitation travertine flower vats, including batching, mixing, mold cleaning, feeding molds, upper staple fibers, and demoulding. , Maintenance, trimming, repairing, brushing, surface coating and other steps. The imitation travertine flower vat of the present invention has clear and natural texture, good product strength, light weight, hard surface, wear-resistant, not easy to delaminate and powder, convenient for mass production, low cost, easy to control product color difference stably, The decorative effect is good, and at the same time, it can avoid a large amount of mining of natural travertine in nature, and can digest mine waste to protect the ecological environment.

The invention discloses a compression-resistant and carbonation-resistant recycled concrete and a preparation method thereof, belonging to the technical field of concrete. Concrete raw materials include 250-290 parts of cement, 55-70 parts of silica fume, 30-45 parts of fly ash, 1050-1120 parts of modified recycled coarse aggregate, 700-730 parts of sand, and 10-15 parts of redispersible latex powder 3-5 parts of water reducing agent, 140-160 parts of water. Preparation of modified recycled coarse aggregate: 100 parts of water glass with a mass concentration of 5%, 20-30 parts of diatomaceous earth, 10-20 parts of zeolite powder, 8-15 parts of colloidal graphite powder, 1-15 parts of silane coupling agent Mix 3 parts evenly to obtain aggregate modification solution, soak the recycled coarse aggregate raw material in it, drain, and roast at 180-200°C for 1-2h. Preparation of concrete: Prepare modified recycled coarse aggregate; mix cement, sand, redispersible latex powder, and water evenly, add modified recycled coarse aggregate and mix evenly, add water reducing agent, silica fume and fly ash and mix evenly . All the concrete of the invention adopts the modified recycled coarse aggregate as the coarse aggregate, and the final prepared concrete has the characteristics of compression resistance and carbonation resistance.

The disclosure column of the present invention is a green, low-carbon and environment-friendly road structure using recycled materials, including subgrades and road surfaces arranged sequentially from bottom to top, subgrades including embankments and road beds arranged sequentially from bottom to top, and embankments are regenerated from urban construction waste The road bed is made of recycled graded mixture of urban construction waste; the pavement includes a cushion, subbase, base, lower layer, middle surface and upper layer arranged in sequence from bottom to top, and the cushion is made of Made from recycled graded aggregates from construction waste. The invention can not only ensure the needs of the current traffic development, but also solve the environmental problems left over from the urban development and the problems that the basic engineering construction destroys the exploitation of natural resources.

An adhesive patch for external use which is significantly inhibited from causing a rash, is less irritative to the skin, and sufficiently retains adhesion to the skin. The adhesive patch is characterized by employing a pressure-sensitive adhesive base into which a sucrose fatty acid ester has been incorporated. It does not exert physical influences on the skin, such as stresses imposed on the skin during wear and upon peeling, while sufficiently retaining adhesion to the skin. It is significantly inhibited from causing a rash, and the skin irritation thereof has been minimized. This adhesive patch for external use has ideal, lowly irritative properties which have been impossible to any conventional adhesive patch for external use.

The embodiment of the invention discloses an environment-friendly food material edge-wrapped honeycomb and a production and boxing method. The honeycomb includes a bottom support plate and through holes arranged on the four corners of the bottom support plate. A support is fixedly installed in each through hole. Vertical rods, the inside of the supporting vertical rods are provided with vertical through holes, and there is a food material wrapping board between two adjacent support vertical rods, and several layers of protective films are wrapped on the outside of the food material side boards; the production box The specific method is as follows: put the food-wrapped honeycomb into the beehive, and the bees make a nest in the food-wrapped honeycomb to produce honey; the food-wrapped board is waxed to form a beeswax honeycomb; After taking out the edge honeycomb, drive out the bees, and directly put the edge honeycomb into the packaging box; the edible material is used as the edge wrapping design around the honeycomb, so that the honeycomb can be directly sent to the mouth for consumption, and at the same time prevent the honeycomb from being in the mouth. In case of damage and leakage of honey during transportation.

The invention discloses a nutrient solution matrix-free seedling raising and cultivating system and a seedling raising method. The system comprises a nutrient solution seedling raising tank, a seedling grid plate, seeding paper and covering paper, wherein the nutrient solution seedling raising tank is filled with water or nutrient solution; the seedling raising grid plate is arranged on the nutrient solution seedling raising tank, and water through holes are formed on the side faces of the grid plate holes of the seedling raising grid plate; the seeding paper is laid on the seedling raising grid plate; and after seeding, the covering paper is covered on the seeding paper bearing seeds. The method comprises: sowing seeds on the seeding paper, covering the covering paper with high water absorbing performance and breathability and covering the perlite or vermiculite on the covering paper; and after the seeds germinate, the roots of the seedlings penetrate the seeding paper to grow downward to absorb water and nutrients from the nutrient solution below. When the system is used, a matrix which is adopted by the conventional industrial seeding raising technique is not used, the overall accurate control over the temperature, water, nutrient and oxygen required by plants for growth in the whole seedling raising process is realized, the industrialization of the seedling raising processis realized, and the uniformity, strong seedling rate and robust degree of the seedlings are improved.
