Problems solved by technology

At present, the raw materials widely used in the production of "green degradable materials" are mainly pulp, with a small amount of straw, wheat straw, bagasse and other crop straw fiber materials. Although the materials are environmentally friendly, they are facing shortage of raw materials, complex production processes, and high production costs. Disadvantages such as low economic benefits

Embodiment 1

[0031] First of all, the cassava residues and distiller's grains should be handled separately.

[0032] After the cassava slag is sieved out, the content of starch and other impurities is relatively high. It should be adjusted to the required concentration, and it will be finely ground by a double disc mill to make the fiber length reach the range of 0.01-0.08mm. After that, pour it out and wash it repeatedly. The purpose is to remove other impurities such as starch and silt. Then filter and dry the water for later use, and the water content is controlled between 75% and 80%.

[0033] Since the distiller's grains have been cooked, fermented, and saccharified, the starch content is greatly reduced, and the starch is basically converted into maltodextrin and maltose, which are more viscous, and the protein and fiber content are increased. It should be adjusted to a concentration of 10% to 15%, and it will be finely ground by a double-disk mill to make the fiber length reach the...

Embodiment 2

[0037] As in Example 1, soak the washed and dried distiller's grains in water and stir to make them evenly dispersed.

[0038] The total weight is 4kg, the dry pulp and distiller's grains are mixed according to 6:4, that is, 2.4kg of dry pulp and 1.6kg of dry distiller's grains are mixed, and 330 kg of water is added, and the concentration is about 1.3%. After stirring evenly, add 250g of talcum powder and 1% cationic starch Paste liquid 30ml, anti-mildew preservative IP-20D 1.5g, adhesive 0.5% PVA 200ml, after stirring for 3-5 minutes, add 40g of industrial dyes, color-fixing agent NaCl 12g, waterproofing agent AKD emulsion 1800ml, add water 500kg after stirring for a few minutes When diluted, the concentration is 0.5%, and the machine is used to produce degradable flower pots. The production conditions are: embryo suction time 25-30 seconds, drying temperature 185-205 ℃, drying time 100-130 seconds (production conditions can be adjusted according to specific conditions), col...

Embodiment 3

[0040] Soak the washed and dried cassava residue in water and stir to make it evenly dispersed, and mix it with waste paper pulp in a ratio of 5:5.

[0041] 2kg each of dry paper pulp and cassava residue, add 250kg of water, the concentration is about 1.6% at this time, after stirring evenly, add 250g of talcum powder, 40ml of 1% cationic starch paste, stir for a few minutes, add 250ml of AKD emulsion, 8ml of oil repellent, After stirring for a few minutes, add 1000kg of water to dilute, and when the concentration is 0.3%, it is used on the machine to produce paper for industrial outer packing boxes. Such as: fiber cardboard, corrugated paper, liner paper, industrial packaging paper and other paper industries that do not require high appearance quality. Some customers have special requirements and can appropriately increase the amount of additives.

[0042] (1) Fiber cardboard: Fiber cardboard, also known as paper fiber molding material, is an elastic and degradable material ma...

Abstract

The invention discloses a method for producing a novel degradable material by manioc dreg and pot ale and comprises the following steps: the manioc dreg or the pot ale is purified, ground, cleaned, drained and mixed with dry paper pulp according to the weight proportion of a to b; wherein, the a lies between 2 and 5, and the b lies between 5 and 8; a papermaking addition agent is added, and the mixture is molded and parched, thus obtaining the degradable material product. Paper pulps of vegetable fiber such as waste newspapers, carton paper, paperboards and other paper pulps of vegetable fiber materials can be taken as the dry paper pulp. The method for producing the novel degradable material by the manioc dreg and the pot ale adequately utilizes wastes of manioc resources such as the manioc dreg, the pot ale to produce the novel industrial degradable material with good quality and low cost, replaces degradable materials of cellular plastics, and not only solves the difficult processing problem of wastes and changes wastes into valuable, but also effectively generates the actions of controlling and eliminating the white pollution; furthermore, the method for producing the novel degradable material by the manioc waste and the pot ale has uncomplicated technique, short production period, low cost, low energy consumption, simple and convenient operation, high product stability and good economic, social and environment-protective benefits.

Description

technical field [0001] The invention relates to a production method of a degradable material. In particular, a method for producing new degradable materials from cassava residues and distiller's grains. Background technique [0002] Guangxi is the largest cassava planting base in the country, with a planting area of ​​more than 4 million mu, and a total cassava production of 8 million tons. Both the planting area and fresh cassava production account for about 60% of the country's total output. During the "Eleventh Five-Year Plan" period, Guangxi will vigorously develop the cassava industry, and it is estimated that the annual output of fresh cassava in the region will reach 18 million tons. After cassava is processed into starch, alcohol and other substances, the remaining substances are cassava dregs and distiller's grains. Cassava dregs and distiller's grains contain a large amount of fiber and residual starch (the contents of cellulose and starch are 36% and 46% respect...
