Abstract
The invention provides a combined foaming plastic production nursery site. Originally, foaming plastic is polystyrene; the foaming plastic, micron-grade SiO2 and NaHCO3 are foamed in a batch-type 110-Z type foaming machine according to the weight ratio of 100: 2.3: 1.1; a CO2 physical foaming agent with the purity of 99% is injected into a molding section of a molding machine until combined foaming is realized; and the foaming temperature is 120+/-2 DEG C and the pressure is 0.329Mpa. With the adoption of the technical scheme, the cell density can be enhanced, and greater size and foaming rate are obtained; cells are not broken and have a complete pyritohedron cell shape; and the foaming rate is 16.21-18.42 times and the cell density is 3.02*10-3.53*10 per square centimeter.
Description
Technical field
The present invention relates to plastic foamed technology, relate in particular to a kind of combination foamed plastic and produce seedlings nursing plate.
Background technology
Seedlings nursing plate is as the important carrier of plant husbandry industrial seedling rearing, in the seed seedling-raising process to the water conservation of seed, protect fertile, insulation plays a part crucial, the durability of seedlings nursing plate, protect fertile, water-retaining property is inseparable with the foaming of raw material polystyrene, the conventional high-temperature high pressure adds the physical foaming agent method, the polystyrene raw material that obtain are many, density unevenness, resistance to water, many drawbacks such as nutrient preserving capability difference shaped article structural instability, in seedling raising process, cause water falling hole variable big, matrix runs off in a large number, and the seedling early growth environment is poor, can not get desirable seedling, directly influenced the productivity effect of plant husbandry, this foaming method improves the guarantor fertilizer of floating seedlings dish in growing seedlings to greatest extent, and is water-fast, durability, adopt new foaming method, namely made up foaming method.
Summary of the invention
The purpose of this invention is to provide a kind of combination foamed plastic and produce seedlings nursing plate, the guarantor's fertilizer of seedlings nursing plate of realizing foaming, water-fast, durable molding structure are stablized, and inexpensive, environmentally safe provides material base and condition for cultivating high-quality seedling.
The technical scheme that adopts: with physical blowing agent and the combined p-poly-phenyl ethene of CBA foam production seedlings nursing plate.
Select CO for use
2The main foaming agent of crop haircut bubble is blowing promotor with sodium acid carbonate (NaHCO), uses micron order SiO
2Do the heterogeneous nucleation agent in the foaming process, blowing temperature is with 120 ℃ ± 2, and pressure 0.294～0.329Mpa makes the CO in the goods
2Gas increases abscess-size and cell density strengthens, and the abscess crack-free has more complete pyritohedron abscess pattern.
Be the expanded material polystyrene, micron order SiO
2, NaHCO
3The 100:2.3:1.1 match ratio is mixed by weight, foams in batch (-type) 110-Z type foaming machine, and injecting purity at the profiled section of plastic foam make-up machine is 99%CO
2Physical blowing agent makes up foaming.
Adopt the beneficial effect of the technical program: can strengthen cell density, bigger size and expansion ratio are arranged, and the abscess crack-free has complete pyritohedron abscess pattern, expansion ratio is at 16.21-18.42 times, and cell density is 3.02 * 10～3.53 * 10/cm
2
The specific embodiment
A kind of combination foamed plastic of the present invention is produced seedlings nursing plate, and the specific embodiment is described below: foamed plastic be polystyrene, micron order SiO originally
2, NaHCO
3100:2.3:1.1 foams in batch (-type) 110-Z type foaming machine by weight, and injecting purity at the profiled section of make-up machine is 99%CO
2Physical blowing agent is carried out the combination foaming, blowing temperature 120 ℃ ± 2, pressure 0.329Mpa.
Claims (1)
1. a combination foamed plastic is produced seedlings nursing plate, it is characterized in that: described foamed plastic be polystyrene, micron order SiO originally
