Definitions
- the present invention relates to a method for producing non-paper pulp natural fibers of paper pulp molded products, especially relates to a method that recycle and reuse the traditional industrial waste with coarser natural fibers such as palms, hemp and coconut shells to reproduce to a moldable pulp by steps such as scouring and bleaching, so as to produce a paper molded product. Therefore, the problem that paper pulp is hard to be obtained may be solved, and the cost of the paper molded product may be decreased.
- a well known paper molded packing product material especially to a fibrous material used for a packing container with environmental protection effect or decomposable.
- conventional paper production technology can not deal with harder fibers, therefore, the nonpoisonous plants such as wood pulp, sugar cane bagasse, phragmites communis, straw pulp, grain shells, starch and recycled paper are the major raw material, however, the amount of the above mentioned paper pulp raw material is limited, especially that trees are the primary raw material for producing paper pulp, and are the max number of usage, which seriously persecute the ecological environment of the earth. Therefore, some proprietors and nations who care the environmental protection have tried hard to find the replace product.
- the primary object of the present invention is to provide a method for producing non-paper pulp natural fibers of paper pulp molded products, which recycle and reuse the traditional industrial waste which has never been used before, such as palms, hemp and coconut shells, to both solve the problem of waste in the processing products nations and areas that produce palms, hemp and coconut shells (trees), and decrease the logging of trees to protect the ecological environment of the earth.
- the another object of the present invention is to provide a method for producing non-paper pulp natural fibers of paper pulp molded products, which produces the paper molded products by recycling and reusing the traditional industrial waste that has never been used before, such as palms, hemp and coconut shells, to decrease the cost.
- the producing steps of the present invention comprising: a. scouring, soaking and stirring the non-paper pulp natural fibers with water in a tank, wherein the ratio of the natural fibers to water is 1:10, adding 0.01% ⁇ 5% parts NaOH, scouring agents, penetrating agents and bleaching stabilizers, relative to the natural fibers, and being well stirred; b. bleaching, 1% ⁇ 10% parts H2O2 relative to said natural fibers is added well stirring of step a for stirring to an appropriate degree, for bleaching and being heated to about 90°C with soaked time in 30 ⁇ 90 minutes; c.
- step b washing, obtaining said non-paper pulp natural fibers after finishing bleaching of step b, then be soaked into the cold water with 0.01% ⁇ 5% Sodium Hydrosulfite about 30 minutes; d. dehydrating, taking out said non-paper pulp natural fibers after washing and swing or air-drying it; e. pulverizing, putting said non-paper pulp natural fibers into the pulverizer after dehydrating; f. pulping, putting said non-paper pulp natural fibers into the mixing pulp tank with adding the water to become a well mixed natural fibers pulp after pulverizing, wherein the ratio of the natural fibers to water is 1:10; g.
- cross-linking agents containing nonionic compounds and cationic compounds with said non-paper pulp natural fibers in a storage tank to become a moldable pulp after pulping, wherein said cross-linking agent is made with 0.75% ⁇ 5.4% parts Fluorochemical serice, 0.9% ⁇ 7.2% parts High polymer compound, 0.15% ⁇ 0.54% parts Aliphatic polyamine and 0.75% ⁇ 9% parts Alkyl acryl copolymers, relative to the amount of said natural fibers; h.
- paper pulp molding spraying a releasing harmonizing agent membrane on the surface of a paper molding mold, applying appropriate moldable pulp and then being heated to about 120°C , 10 ⁇ 20 minutes for drying thermosetting, wherein said releasing harmonizing agent is mixed from 9.5% parts releasing agent, 0.5% cross-linking agent and 90% dilute water; i. releasing, releasing products from mold by air-blowing to obtain paper pulp molded products.
- step f wherein after pulverizing said non-paper pulp natural fibers, further adds a part of paper pulp, recycled paper, or thermal resistance additives containing anionic compounds with equal amount of non-paper pulp natural fibers, and then, being stirred with water to form a uniform natural fibers pulp; said thermal resistance additives containing 50% ⁇ 80% parts Inorganic Aluminum Silicate and 1.5% ⁇ 9% parts Natural wax emulsion, relative to said natural fibers.
- a chemical polymer such as PP, OPP, OPS, PE, PET, or environmental protection waterproof, watergrease water based paint
- a chemical polymer such as PP, OPP, OPS, PE, PET, or environmental protection waterproof, watergrease water based paint
- the paper molded products produced by above method use the traditional industrial such as palms, hemp and coconut shells (trees) as the major raw material, the cost may be decreased, the problem of industrial waste may be solved, and the logging amount of trees may be decreased to protect the ecological environment.
- traditional industrial such as palms, hemp and coconut shells (trees)
- the method for producing non-paper pulp natural fibers of paper pulp molded production of the present invention comprises the steps of:
- non-paper pulp natural fibers of paper pulp molded production of the present invention which recycle and reuse the traditional industrial waste such as palms, hemp and coconut shells, after a series special steps such as scouring and bleaching, to both solve the problem of waste in the processing products nations and areas that produce palms, hemp and coconut shells (trees), and decrease the logging amount of trees to protect the ecological environment; furthermore, the cost may be decreased efficiently and the competition ability may be increased by the method for producing non-paper pulp natural fibers of paper pulp molded production of the present invention.
- a part of paper pulp or recycled paper is mixed with said pulverized non-paper pulp natural fibers to meet the requirement of the different production place, so as to increase the using range and economical benefit; or thermal resistance additives containing anionic compounds is added, the amount is equal to non-paper pulp natural fibers, and 10 times amount of water is added together, then, being stirred to form a natural fibers pulp which can be used at 200 °C to meet the requirement of oven or microwave; said thermal resistance additives containing 50%-80% parts Inorganic Aluminum Silicate and 1.5% ⁇ 9% parts Natural wax emulsion, relative to said natural fibers.
- a chemical polymer such as PP, OPP, OPS, PE, PET, or environmental protection waterproof, watergrease water based paint
- a chemical polymer such as PP, OPP, OPS, PE, PET, or environmental protection waterproof, watergrease water based paint
