Seed coating agent special for direct seeding rice

InactiveCN101310582AEfficiently regulate changes in moisture contentRegulating changes in moisture contentSeed coating/dressingDiseaseAdditive ingredient
The invention discloses a seed coating agent specially used for direct seeding rice, which is characterized in that the seed coating agent mainly contains the following ingredients by weight: 2 to 8 percent of super absorbent resin, 1 to 5 percent of oxygenates, 0.1 to 0.5 percent of sparrow and rat destruction agent , 0.5 to 2 percent of bactericide, 0.5 to 2 percent of pesticide, 0.02 to 0.2 percent of plant growth regulator, 3 to 10 percent of trace element fertilizer and the margin is special type mineral clay. The powder raw materials are crushed to more then 100 meshes and are mixed evenly, the mixture is coated on the surfaces of rice seeds by a seed-coating method for direct sowing, thus clay sacculus integrating 'a small water reservoir, a small oxygen reservoir, a small drug storage and a small fertilizer storage' are formed around the rice seeds and at the roots of seedlings; the seed coating agent has the effects of preserving and providing water, ventilating and providing oxygen, promoting seedling emergency, preventing diseases and killing pests, preventing mice and destructing sparrows, strengthening seedlings and roots and increasing production. The seed coating agent is also characterized by low dosage, low cost, simple and convenient operation, and the like, thereby being applicable to coating rice seeds which are directly sowed both on flooded paddy fields and dry paddy fields.

Crack-resistant abrasion-resistant hydraulic concrete and preparation method thereof

The invention discloses crack-resistant abrasion-resistant hydraulic concrete and a preparation method thereof. The hydraulic concrete comprises materials of cement, sand, stones, a polypropylene fiber, a water reducing agent, an air entraining agent and water, and is characterized in that: an internal curing agent and silica fume powder are added; by adopting the internal curing agent as a super absorbent resin, internal maintenance of the concrete is enhanced, the concrete shrinkage is reduced, the abrasion resistance of the concrete is improved, and the crack resistance of the concrete is improved; by adopting the silica fume powder, the concrete mixture performance and abrasion resistance are improved, the comprehensive utilization of industrial wastes and resource and energy conservation are realized, and the environment is protected; and taking concrete at C40 strength grade as an example, the abrasion resistance is 23.52h/kg/m<2>, the early plastic shrinkage crack resistance reaches the first grade, cracks are not formed on the surface of the concrete, an air shrinkage value within 28 days is 162*10<-6>, and the autogenous volume deformation within 28 days is 20*10<-6>. The technical scheme is simple in technical operation, readily available in raw materials, lower in production cost and better in economic and social benefits.

Computerized, monitored, temperature affected, delivery system for perishable goods

A "safe delivery"SM system for delivering perishable groceries (120/120'), including an inexpensive, corrugated cardboard box (100); a source of cold (or heat as needed) maintaining the temperature inside the box within a desired temperature range for hours, using an all encompassing pouch of packet material (110/10), used individually (FIGS. 2 & 3) or collectively (FIGS. 5 & 6), with each packet (17) containing a super-absorbent polymer (14, FIG. 12) which is hydrated (14', FIG. 12A) and then either frozen (e.g., in a freezer) or heated (e.g., in a microwave), without producing moisture as the polymer returns to its natural state; a protective cover (130) protecting the box and its contents from heat radiation (e.g., sunlight). Other components (e.g., bubble wrap 140, sealing tape 133) prevent heat attacking convection and/or conduction, with the cover having multiple plies with an outer metallized surface (131); a time/temperature monitoring alert (134) indicating when either a maximum predetermine temperature or a maximum allowed, elapsed time from packing to opening has been exceeded. If so, the customer knows that the perishable items are not warranted to be safe, and the customer is responsible for contacting the purveyor for a return of the goods. A computerized methodology (FIG. 1) insures that the purveyor knows at least approximately when the customer has opened the packed groceries, etc., using a predictive calculator and an automated tracking system, in which the customer is obligated to transmit a unique code, preferably through an automated telephonic or Internet system, when the package is opened.

Ultra-high performance concrete with micro-expansion and compensation shrinkage and preparation method thereof

The invention belongs to the field of building materials, and especially relates to ultra-high performance concrete with micro-expansion and compensation shrinkage and a preparation method thereof. Raw materials include, by weight, the following components: 1 part of cement, 0.05-0.2 part of fly ash, 0.2-0.5 part of silica fume, 0.1-0.25 part of mineral powder, 0.05-0.2 part of quartz powder, 0.9-1.2 parts of quartz sand, 0.04-0.2 part of an expanding agent, 0.01-0.03 part of a water reducing agent, and 0.01-0.03 part of an expansion promotion reinforcing agent. A mixing amount of super absorbent resin is 0.4%-0.8% of a cementing material; a volume mixing amount of steel fiber is 1%-3% of a total volume of the concrete; the water-to-binder ratio is 0.16-0.22; and the compressive strength is 100-160 MPa. The ultra-high performance concrete with the micro-expansion and the compensation shrinkage has the characteristics of micro-expansion, high strength, high toughness, excellent workingperformance, and the like, and solves the problem that the expanding agent is difficult to produce effective expansion in the ultra-high performance concrete with a low water-to-binder ratio, and so,the risk of early shrinkage cracking of the ultra-high performance concrete is reduced, and the ultra-high performance concrete can maintain the micro-expansion for a long time.
