Description
Technical field
The present invention relates to plastic foamed technology, particularly relate 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, to the water conservation of seed in seed seedling-raising process, fertilizer conservation, insulation plays a part key, the durability of seedlings nursing plate, fertilizer conservation, water-retaining property is inseparable with the foaming of raw material polystyrene, conventional high-temperature high pressure adds physical foaming agent method, the polystyrene raw material obtained 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 large, matrix runs off in a large number, seedling early growth environment is poor, can not get desirable seedling, directly affects the productivity effect of plant husbandry, this foaming method, improve the fertilizer conservation of floating seedling tray in nursery to greatest extent, water-fast, durability, have employed new foaming method, namely foaming method is combined.
Summary of the invention
The object of this invention is to provide a kind of combination foamed plastic and produce seedlings nursing plate, realize the fertilizer conservation of foaming seedlings nursing plate, water-fast, durable molding structure is stablized, inexpensive, environmentally safe, provides material base and condition for cultivating high-quality seedling.
The technical scheme adopted: with physical blowing agent and CBA combined p-poly-phenyl ethene foam production seedlings nursing plate.
Select CO
2make the main foaming agent of physical blowing, be blowing promotor with sodium acid carbonate (NaHCO), use micron order SiO
2do the heterogeneous nucleation agent in foaming process, blowing temperature is with 120 DEG C ± 2, and pressure 0.294 ~ 0.329Mpa, makes the CO in goods
2gas increases abscess-size and cell density strengthens, and abscess crack-free, has more complete pyritohedron abscess pattern.
For expanded material polystyrene, micron order SiO
2, NaHCO
3100:2.3:1.1 match ratio mixing by weight, foams in batch (-type) 110-Z-type foaming machine, and injecting purity at the profiled section of plastic foam forming machine is 99%CO
2physical blowing agent carries out combination foaming.
Adopt the beneficial effect of the technical program: cell density can be strengthened, there are larger size and expansion ratio, abscess crack-free, have 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.
Detailed description of the invention
Of the present invention one combination foamed plastic produce seedlings nursing plate, detailed description of the invention is described below: foamed plastic be polystyrene originally, micron order SiO
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 forming machine is 99%CO
2physical blowing agent, carries out combination foaming, blowing temperature 120 DEG C ± 2, pressure 0.329Mpa.
