Abstract
An environmental protection type disposable dinnerware with internal water-proof surface is made up through pulverizing wheat and rice straw, reed, or bran, mixing wheat flour with water to obtain solution Ai and mixing wheat flour and water to form solution B, mixing amino resin powder with solution B to obtain solution C, mixing urea-based solution, flour, solution A and plant fibre powder, hydraulic press to obtain blanks, adding solution C to the internal surface of blank, and hydraulic processing to obtain product. Its advantages are no pollution in its production and high degradation speed.
Description
The present invention relates to the method for a kind of disposable environmental protection tableware and production technique thereof.
Existing disposable degradable tableware, raw material adopts wheat straw, straw, reed or cavings, and processing method is, wheat straw, straw, reed or cavings are macerated mashed, carried out rinsing again, oven dry is handled, and makes paper pulp earlier, again pulp powder is broken into the end, adds tackiness agent, handle forming blank through hydraulic pressure; At the inner-wall spraying water-resisting agent of blank, dry processing again, finish finished product.This processing method, because one ton of paper pulp of every production can produce the sewage about 50 tons, the pollution that causes in the production process is very big, the production cycle is longer, operates more numerous and diverse; And the production cost of paper pulp itself is also higher, and the finished product price of producing is also increased relatively, is unfavorable for promoting.In addition, because paper pulp itself lacks certain rigidity, therefore require product that certain thickness is arranged, thereby the product degradation speed of producing is slowed down.
The objective of the invention is, overcome the shortcoming that above-mentioned disposable degradable tableware and production technique thereof exist, a kind of improved environmental protection type disposable dinner set with water-proof internal surface and production technique thereof are provided.
The object of the present invention is achieved like this.The environmental protection type disposable dinner set with water-proof internal surface production technique is:
A, wheat straw, straw, reed or cavings are ground into the vegetative fiber powder under closed state
B, add water with flour, the ratio in 1: 3～5 fully is in harmonious proportion, and it is stand-by to make solution A;
C, add 100 ℃ water with flour, the ratio according to 1: 0.9～1.1 fully is in harmonious proportion, and makes solution B;
D, add the aminoresin powder that contains formaldehyde 0.03% with solution B, the ratio according to 1: 0.9～1.1 fully is in harmonious proportion, and it is stand-by to make solution C;
E, usefulness contain 50% urine based sols of formaldehyde 0.03%, add flour, add solution A, add the vegetative fiber powder, the ratio according to 1: 3.5～4.5: 7～9: 12～16, under 145～155 ℃ of temperature of hydropress, heat, hydraulic pressure 10～20 seconds is exitted the blank moulding 5～10 times; Mould upper and lower mould space is at 1～1.2 millimeter;
F, add solution C at the blank inwall according to the ratio of weight ratio 1: 0.08～0.12, through hydropress hydraulic pressure venting 1～5 time, 145～155 ℃ of temperature of hydropress, matched moulds solidified 40～60 seconds, went out finished product.
The closed pulverizing of process using of the present invention need not to macerate technological processs such as mashed, rinsing, oven dry, has not only saved human and material resources, also can not produce pollution in the raw material production process.Technology of the present invention need not be made paper pulp with raw material, has kept the original certain degree of hardness of raw material, and the thickness requirement of product reduces like this, so product degradable not only, and degradation speed is very fast.To be immersed in the aqueous solution 24 hours by the product integral body that this technology is made and promptly begin degraded; Imbed in the moist soil 60 days and can be degraded into organic fertilizer fully.Because this product in process of production, has passed through pyroprocessing, so product can refrigerate in subzero 20 ℃ environment, also can be in microwave oven works better.The present invention adds 100 ℃ water mediation with flour, makes solution B; Add the solution C that amino toner mediation is made again, have water-repellancy, make the product inwall have water-proof function.Product of the present invention has added formaldehyde in process of production, so product can be not mouldy.The production technique of twice moulding environmental protection type disposable dinner set with water-proof internal surface provided by the invention, easy and simple to handle, product cost is low, is convenient to promote the use of.
The present invention is provided by following examples.The environmental protection type disposable dinner set with water-proof internal surface production technique,
A, wheat straw, straw, reed or cavings are ground into the vegetative fiber powder under closed state
B, add water with flour, fully be in harmonious proportion in 1: 4 ratio, it is stand-by to make solution A;
C, add 100 ℃ water, fully be in harmonious proportion, make solution B according to 1: 1 ratio with flour;
D, add the aminoresin powder that contains formaldehyde 0.03% with solution B, fully be in harmonious proportion according to 1: 1 ratio, it is stand-by to make solution C;
E, usefulness contain 50% urine based sols of formaldehyde 0.03%, add flour, add solution A, add the vegetative fiber powder according to 1: 4: 8: 14 ratio, under 150 ℃ of temperature of hydropress, heat, and hydraulic pressure 15 seconds is exitted the blank moulding 7 times; Mould upper and lower mould space is at 1 millimeter;
F, add solution C at the blank inwall according to 1: 0.1 ratio of weight ratio, through hydropress hydraulic pressure venting 3 times, 150 ℃ of temperature of hydropress, matched moulds solidified 50 seconds, went out finished product.
1 millimeter of the tableware wall thickness of producing according to this processing method.
