Abstract
The present invention relates to a kind of complete degradable tableware and package made of plant fibre. Its composition is formed from (wt%) 50-95% of plant straw powder, 0.5-30% of non-toxic adhesive and 0.5-30% of edible filler, and its production method includes the following steps: impurity-removing and pulverizing plant straw to 20-80 meshes, adding adhesive, filler and water, uniformly mixing, and placing into mould, pressurizing and heating, pressure is 50-1500 kg/sq.cm, temp. is 50-230 deg.c and solidifying time is 5 sec. to 15 min., then demoulding, impregnating and coating with impervious film, stoving, disinfecting and packaging so as to obtain the invented product. Said invented product can be completely naturally degraded after about 48 days, after having been pulverized it can be used as feed, and after degraded it can be used as fertilizer.
Description
The present invention relates to one and tableware and packing material and the manufacturing forming technique thereof that can high-fallly separate.
Existing disposable foaming plastic tableware with after can not natural degradation, burning discharges harmful gas again, and the residue after burning is grease, also is difficult for decomposing.If reclaiming, its cost are the twices of tableware cost, especially reclaim difficulty.This kind disposable tableware has caused the white pollution and the public hazards of utmost point refractory reason to society.Recently people develop the paper mould disposable tableware again, and this kind tableware is main raw material with the wood pulp, and it can cause the original timber resources that just lacks very much further exhausted, and work in-process will give off a large amount of harmful waste liquids, cause environmental pollution.With its degradation time of back is three months, and its cost is also higher, can not be utilized once more.
A kind of degradable tableware and packing material of manufacturing by string of purpose development of the present invention, this tableware and packing material cost are low, can be as disposable use, and degradation time is short, especially the raw material of its utilization is easy to get, and abundant, moreover this tableware and packing material with after can also be used as feed and fertilizer.Its forming technique is provided simultaneously, and this manufacture method is answered three-waste free pollution.
Tableware of the present invention and packing material are made up of plant stalk powder end, nonpoisonous adhesive, edible compound, they respectively account for following ratio by weight percentage: plant stalk powder end 50～95, nonpoisonous adhesive 0.5～30, edible compound 0.5～30, also soak intrinsic nontoxic antiseepage film on the surface of tableware and packing material, the thickness of nontoxic antiseepage film is 0.1～0.5 μ m.The plant stalk powder end is at least by a kind of composition the in cornstalk powder, straw powder, rice husk powder, sorghum rod powder, bean straw powder end, cotton bar powder, the weeds powder.Nonpoisonous adhesive is at least by a kind of composition the in gelatin, gelatine, white lac, calcium carbonate, cyclodextrin, calcium stearate, zinc stearate, the thermosol adhesive.Edible compound is at least by a kind of composition the in corn flour, wheat flour, lithopone, zinc oxide, the titanium dioxide.Nontoxic antiseepage film is at least by a kind of composition the in edible resin, solvent, the ethyl cellulose.Its manufacture method is: at first the plant straw removed root, remove mud, pulverize then, filter out 20～80 purpose powder, stirring after plant stalk powder end, nonpoisonous adhesive, edible compound, water are mixed joins in the mould, give the mould pressurized, heated, pressure is at 15～1500kg/cm
2, temperature is at 50～230 ℃.The solidified forming time in mould is 5 seconds～15 minutes, with tableware or the nontoxic antiseepage film of packing material dip-coating, dries, sterilizes, packs and get final product after the demoulding.
Cutlery box of the present invention and packing material can be degraded fully at occurring in nature, and degradation time is about 48 days.Because the Main Ingredients and Appearance of plant straw is carbohydrate, starch, protein, calcium, sugar, cellulose etc., moreover nonpoisonous adhesive, edible compound all be suitable for animal edible, so can be used as the feed of animal and fish after this tableware and packing material are pulverized.As its residue is a plant ash after burning, and is a kind of inorganic fertilizer, resigns from office and return home so can become fertilizer after its degraded.And this product cost is low, is that its cost only is 0.13 yuan in the standard bowl of adorning instant noodles.So can become disposable tableware fully.Especially main raw material plant straw source is abundant, can twice laid, turn waste into wealth, and be a kind of benign cycle green product.This product Heilongjiang Province's Food Hygiene Surveillance check detects, and its every index is: potassium permanganate consumption (60 ℃ of water 2h): 40mg/L; Evaporation residue (4% acetate, 60 ℃ of 2h): 30mg/L; Heavy metal is (with P
bMeter)＜1mg/L; Coliform＜30/100g; Pathogenic bacteria: do not detect; Decolorant Test: buffet oil is negative.Every index testing result accord with Q/HX001-1998 regulation.This tableware loaded 90 ℃ of boiling water 30 minutes, did not have distortion, ne-leakage, and 3kg static pressure height change is smaller or equal to 5%.
Embodiment one: present embodiment is made up of following composition by weight percentage, 60 purpose rice husk powder 76, corn flour 18, gelatin 5, suitable quantity of water.The even back injection mould that is mixed is heated, and pressure is 800～1000kg/cm
2, temperature is 160 ℃, mould remaining time is 60 seconds.Dip-coating edible resin film after the demoulding, thickness are 0.2 μ m.Heat again, dry, sterilize, pack and get final product.What this embodiment produced is packing material.
Embodiment two: present embodiment is made up of following composition by weight percentage, 70 purpose cornstalk powder 85, wheat flour 10, gelatine 5, suitable quantity of water.Mix back injection mould and heat, pressure is 900～1200kg/cm
2, temperature is 150 ℃, mould remaining time is 50 seconds.Dip-coating ethyl cellulose and edible resin film after the demoulding, thickness are 0.4 μ m.What this embodiment produced is the disposable tableware plate.
Embodiment three: present embodiment is made up of following composition by weight percentage, 75 purpose straw powder 82, wheat flour 8, lithopone 5, gelatine 2, white lac 3, suitable quantity of water.Put into mould after mixing and heat, pressure is 1000～1400kg/cm
2, temperature is 140 ℃, mould remaining time is 45 seconds.Dip-coating edible resin and solvent membrane after the demoulding, thickness are 0.3 μ m.The tableware that this embodiment produces is a disposable and convenient bread dress bowl.
Degradable tableware of the present invention comprises dish, bowl, spoon, chopsticks, box or the like.Packing material can be used for various packagings for foodstuff, also can be used as household electrical appliance, the commodity packaging of other daily necessities, with after can degrade fully, eliminate environmental pollution.
