Abstract
The degradable tableware and utensils features that their component including non-toxic plant fiber powder 40-70 wt%, starch 10-30 wt%, food level resin 10-30 wt%, and food level wax 2-10 wt%. The said products have smooth surface, high hardness, 3-8 Kg pressure resistance and heat resistance as high as 110 deg.c, can degrade automatically in 48 hr inside water of natural environment, and are easy to produce at relatively lower cost.
Description
The present invention relates to a kind of degradable dinner set or vessel and their production method.
In urban environment, exist at present " white pollution " that cause because of plastics in the rural area by the plant straw, burn as dense crop bar stem such as straw, wheat straw, bagasse, sorghum rod and to bring " black pollution ".
Along with continuous development " white pollution " problem of fast food industry has become particularly distinct issues of environmental protection aspect; existing is the tableware of raw material with polyphenyl alkene; not degrading because of a century in natural environment is that does not get countries in the world; paper table ware and degradable plant fiber tableware have appearred thus; but the paper table ware cost is too high; the cost of every snack container is about 0.40 yuan, and paper industry itself brings pollution, and defectives of deforestation these itself have caused paper table ware to develop.In the production technology of existing plant fiber tableware, mostly adopt and pulverize, glue mixing, airing, pulverize again, stir again, compacting, impregnation (spraying) oven dry, sterilization, these loaded down with trivial details production technologies have caused production cost can not be starkly lower than the paper tableware, in existing technology, at first product appearance is rough, coarse and quality is not hard, owing to use edible glue, so can high temperature resistant (80 ℃-100 ℃) also not possess use of practicality such as Chef Kang's noodle soup etc., simultaneously because ability is not higher than 60 ℃ water temperature so table-ware disinfection is brought serious inconvenience, aspect degraded, because of its surface employing impregnation (spraying) or blister-pack, so after compositions such as string degraded wherein, edible glue, films etc. exist open-air as residue, so accumulate over a long period, certainly will cause new pollution, in addition, the time of natural degradation is still longer in water, process aspect is more complicated also, does not therefore still have large batch of degradable dinner set or vessel to come out so far.
The object of the present invention is to provide a kind of degradable dinner set or vessel and production method thereof of disposal molding, it can overcome some shortcomings of the prior art.
Technical scheme of the present invention is achieved in that a kind of degradable dinner set vessel, it is characterized in that: it is made up of non-toxic herb fiber fine powder, starch, food level resin, food wax, and their weight percentages of components is: non-toxic herb fiber fine powder 40-70%, starch 10-30%, food level resin 10-30%, food wax 2-10%.
The production method of a kind of degradable dinner set or vessel, it is characterized in that: choose the non-toxic herb straw and be ground into fine powder after drying, cross the above sieve of 60 orders, fine powder after the screening is poured in the mixer by 10-30% by 15-25%, food level resin by 40-70%, starch and stirred, will evenly be sprayed at (each above component all is weight percentage) in the mixer after the fusing of 2-6% food wax then; The raw material that stirs is poured in the mould that is heated to 150 ℃-200 ℃ and pressurizeed, pressure is transferred to the 25-30 ton, pressurize 5-15 gets final product the demoulding after second, can case after the sterilization that at last finished product after the demoulding carried out disinfection.
The present invention is owing to adopt the different production methods of disposal molding, make manufacture craft greatly simple, personnel and equipment investment have been reduced, reduced energy consumption, thereby reduced manufacturing cost widely, a bowl for snack holder basin production cost is only about 0.2 yuan, and smooth in appearance, nothing comes off, and quality is hard, but 3 kilograms-8 kilograms of resistance to compressions, high temperature resistantly reach 110 ℃, this product can be degraded after 48 hours under the natural environment in the water in the open air voluntarily aspect degraded, because of adopting the food resin, food wax is made binding agent, turns to organic fertilizer or feed so all exist with pulverulence after the degraded, the proportion of this product is greater than water in addition, so in the river, to can't see a floating thing on the river surface, thereby stop the new pollution that brings in the degradation process, these characteristics be other like product can't than.The present invention has remarkable social benefit and economic benefit.
Below the invention will be further described and provide embodiment.
This product is by non-toxic herb fiber fine powder, starch, the edible resin, edible wax is formed, through the moulding of mould pressing one-time, the non-toxic herb fiber, commonly used generally have a straw, bagasse, cavings, the grass bits, straw, reed rod, sorghum rod, beans bar stem and other plant stem or other string, choose the non-toxic herb straw and be ground into fine powder after drying, this non-toxic herb straw fine powder was wanted 60 orders with top sieve, food level resin can adopt ethyl-amine resin or other amine resin, fine powder after the screening is pressed 40-70%, starch is pressed 15-30%, food level resin is poured in the mixer by 10-30% and is stirred, evenly be sprayed in the mixer after then the food wax of 2-6% being dissolved, the raw material that stirs is poured in the mould that is heated to 150 ℃-200 ℃ again and pressurizeed, the material of mould can be selected 45# medium carbon steel for use, make through forging and pressing, pressurization can be used hydraulic press, pressure is transferred to 25 to 30 tons, pressurize 5-15 gets final product the demoulding after second, single mode can be done two in one minute, again through sterilization, can case after the sterilization.
