Abstract
The recoverable dispensable corn chopsticks are made with corn and glutinous corn in the weight ratio of 10, and through mixing, soaking in hot water at 30-40 deg.c, draining, extrusion and maturing at 100-120 deg.c in high temperature extruder to form plate, forming at 150-180 deg.c in high temperature settling machine, stoving at 150 deg.c for 40-50 sec and packing. Of the material, corn has high cellulose content and glutinous corn can raise the product strength. The recoverable dispensable corn chopsticks product has relatively high strength, fixed shape, low power consumption, low cost and no pollution. The used chopsticks may be recovered to produce feed.
Description
Technical field:
The present invention relates to the manufacture method of throwaway chopsticks, especially relate to a kind of manufacture method of the recyclable disposal corn convenient chopsticks that utilizes again.
Background technology:
In real life, chopsticks can be classified as first of the tableware consumption as people's the instrument of having a dinner.According to summary statistics, national consumption per day is about 1.1 hundred million pairs, and the general throwaway chopsticks of existing market all are to make raw material with timber, and cost is than higher, and falls trees in a large number, has caused soil erosion, and drought and waterlogging takes place, and destroys ecological environment.According to statistics, 13.6 ten thousand hectares of the annual loss area of woods of China, this causes great waste to the forest reserves, and its consequence is hardly imaginable.In addition, the material characteristic of timber has determined that the craft precision of its processing is very low, and horizontal dimension situation frangibility, distortion appear in product, and degradation time is long, and environment is caused severe contamination.Therefore, seek the alternative timber in new material source and make institute's urgency that chopsticks have become state with advanced person's technology, the people's is required.
Summary of the invention:
Technical problem to be solved by this invention provide a kind of aboundresources, with low cost, machining accuracy is high, the manufacture method of frangibility, distortion and the recyclable corn convenient chopsticks that utilizes again not.
Manufacture craft of the present invention is as follows:
Corn is mixed with the ratio of 10:1 with glutinous corn, soaked 8-10 hours in 30-40 ℃ warm water, draining drops into high-temperature extruder and becomes tabular at 100-120 ℃ of squeezing, maturings, once finalize the design at 150-180 ℃ by the high-temperature shaping machine again, can pack in 40-50 seconds 150 ℃ of oven dry.
High temperature soaks the surface fibre dissolving in order to prevent chopsticks from soaking partly for a long time, and chopsticks can be carried out press mold processing or high temperature and soak the film processing, 80-100 ℃ of the mold temperatures of press mold, pressure 10-20MPa, 2-5 seconds time, the temperature that high temperature soaks film is 110-140 ℃.
Advantage of the present invention is as follows:
1, adopting corn is that raw material is because the fiber content of corn self is wooden 46.6%, mix with glutinous corn and can improve 28 percentage points of its intensity, in addition, being extruded to shape by high temperature has increased molecular structure density, can improve its intensity 19.2% again, it is wooden 93.8% that finished fiber intensity total amount can be reached, the machining accuracy height, and product is indeformable.
2, because corn has easy fragmentation, the characteristics of being convenient to finalize the design under slaking for advantage has been created in the foundation of high-speed automated production line, are saved power resource simultaneously relatively.
3, cost is low, pollution-free, and used chopsticks can be used as feed and recycle, and benefit can be nearly 1.8 times of wood-based product, can make 3-4 times of corn increments.
4, save the forest reserves, keep ecological environment.
Heatproof of the present invention is tested as following table:
| Heating is 2 hours in 100 ℃ of boiling water | Indeformable |
| Placed 30 days for-20 ℃ | Indeformable |
| 140 ℃ of heating of oil temperature 2 hours | Indeformable |
| High-temperature sterilization in the micro-wave oven | Indeformable |
