Abstract
A biodegradable disposable food or beverage container or packing containers is made up of calcium-contained, ore powder (75-80%), degradation aid (10-15%), reinforcing agent (3-5%), adhesive (1.5-3%) and water-proofing agent (3-5%) through selecting raw materials, mixing, stirring, vacuumizing, putting in mould, rotating or high-pressure shaping, baking blank, demoulding, spraying water-proofing agent, baking, ultraviolet sterilizing and packaging. Its advantages include richly available materials, low cost, simple technology, enough strength and rigidity, and no environmental pollution.
Description
The present invention relates to bio-degradable disposable food containers and packaging vessel, the invention still further relates to the manufacturing process of this food and drink tool and packaging vessel.
Current, environmental protection, hygiene and health are problems that people very pay close attention to, the a large amount of containers, packing and the apparatus that relate to meal, drink, and many industry, agricultural and the commercial solids disposable packaging container that uses, but mostly by difficult natural degradation not even the raw material of natural degradation make, its waste becomes the big public hazards destroying environment, threaten human hygiene and health, is called " white pollution that white garbage forms " by people.In order to solve " white pollution " problem, people have proposed many schemes, as with environmental protection type food and beverage utensiles and the packaging vessel as basic material such as paper substrate, vegetable fibre and starch, but be difficult to mostly be accepted by people, more difficultly promote the use of on a large scale, maximum problem is, the one, and production cost is higher relatively, and the 2nd, its strength and stiffness are often barely satisfactory.The CN1222329A patent application of China Intellectual Property Office's bulletin, owing to the defective of its prescription and process program, in it was implemented, parison and mould were affine, cause demoulding difficulty, and parison is prone to be full of cracks in drying process, cause the low deficiency that waits of yield rate.
The objective of the invention is at the deficiencies in the prior art, the one, the material prescription of a kind of bio-degradable disposable food containers and packaging vessel is disclosed, the 2nd, the manufacturing process of this food and drink tool and packaging vessel is disclosed.
The present invention is directed to the deficiencies in the prior art, for realizing purpose of the present invention, propose the corresponding techniques scheme: the material prescription of bio-degradable disposable food containers of the present invention and packaging vessel is that main component is calcic ore powder, stiffeners, tackiness agent, helps and separate agent and waterproofing agent, it consists of: calcic ore powder 75%-80%, help and separate agent 10%-15%, stiffeners 3%-5%, tackiness agent 1.5%-3%, waterproofing agent 3%-5%, all percentage ratios are weight percentage.The present invention chooses the calcic ore powder as base material, be equipped with corresponding stiffeners, tackiness agent again and help and separate agent, behind the hot setting, can guarantee that bio-degradable disposable food containers of the present invention and packaging vessel product not only have enough strength and stiffness, and can realize low cost production, degraded back environmentally safe.The design and manufacture technology of bio-degradable disposable food containers of the present invention and packaging vessel for select materials → mix → stir → vacuumize → drop into mould → rotation or high-pressure molding → parison oven dry → demoulding → spraying waterproof agent → finished product oven dry → disinfection by ultraviolet light → packing.Take all factors into consideration the requirement of product performance, cost and manufacturing process, the aspect of selecting materials is preferentially chosen: the calcic ore powder is that granularity is a 200-250 purpose food grade lime carbonate, also can choose 200 purpose wilkinites or 200-250 purpose oyster shell whiting etc.; Helping and separating agent is flour or starch; Stiffeners is velvet-like jute fibre, bastose or other non-toxic herb fiber for pulverizing; Tackiness agent is high-tech microniological proudcts microbial polysaccharide XC (xanthan gum), not only has excellent adhesion performance, the favourable parison demoulding, product surface gloss is attractive in appearance, also particularly can significantly improve quick under field conditions (factors), the abundant biological degradation index of bio-degradable disposable food containers of the present invention and packaging vessel, tackiness agent can also be selected Mierocrystalline cellulose (CMC, CMS), latex, gelatin etc. for use; Waterproofing agent is a food-grade alcohol dissolubility resol (PP).Mix, stirring technique is designed to: will help and separate agent flour or starch breaks into pasty state with boiling water (90 ℃-100 ℃), with the normal temperature tap water itself and calcic ore powder, stiffeners, tackiness agent are mixed again, not only can effectively solve parison and mould is affine, the problem that is difficult to the demoulding, and can significantly improve the yield rate and the surface smoothness of product.Vacuumize in the vacuum stock preparation mill and finish, can get rid of the air in the blank of stirring, kneading, improve the qualification rate and the visual appearance of product greatly.Moulding process is designed to rotation or high-pressure molding, rotoforming is suitable for rotating the symmetric form formed product, high-pressure molding is suitable for non-rotating symmetric form formed product, design corresponding mould, the products such as disposable packaging container of making bio-degradable disposable food containers of the present invention and packaging vessel and can be different food and drink tool such as bowl, basin, dish, cup, chopsticks, spoon, dish, bucket or industry, agricultural and commercial solids are not difficult.Stoving process is designed to secondary drying technology, and it is to toast 20-30 minute down for 100 ℃-150 ℃ in temperature that parison is dried, and the finished product oven dry is to toast 10-15 minute down for 60 ℃-70 ℃ in temperature.Spraying waterproof agent technology is the work in-process that parison is dried into to be entered the spraying specific equipment spray one deck waterproofing agent, reach even, the exterior appearance of internal layer spray, on the one hand be can guarantee product of the present invention store and use in not by deliquescence or leakage, be on the other hand do not influence after breaking under field conditions (factors) fast, abundant biological degradation.
Bio-degradable disposable food containers of the present invention and packaging vessel, material price is cheap, and making method is simple, the approximate pottery of smooth finish, ultimate compression strength is big, easily degraded (2-3 month can reduce the Nature), production cost is low.According to GB18006.1-1999 standard test qualified (see attached assay, submitted sample is a disposable degradable bowl of the present invention), reached purpose of the present invention through authoritative product quality supervision and inspection department.
