Abstract
The present invention provides a disposable tableware made up by using crop wastes, such as stalks, straws and husk and adding a small quantity of chemical raw material. Its preparation method includes: adding carboxymethyl cellulose, polyurethane and water to beating machine for beating; pouring said material into stirring mill: adding pulverized stalks, straws and husk powder and heavy calcium carbonate; stirring; sheeting and extruding-forming; microwave drying and hardening; drying in tunnel kiln; cooling by airing to room temp.; sprayingpolyurethane varnish; drying; secondary spraying, drying and cooling by airing. Said invented product is non-toxic, low in cost, quick in degradation speed, odourless, acid-resistant, alkali-resistant and free from environmental pollution, etc..
Description
The prescription of a kind of crop stalk, rice husk system disposable tableware and processing method thereof belong to the dinner ware made field, and the packaging for foodstuff field.
At present, be used to make dinner ware made and mainly contain three kinds of raw materials: the Poly Foam goods are polyethylene products of making blowing agent with fluorine Lyons, utmost point difficult degradation, even be embedded in the soil 100 years also imputrescibility, can not natural degradation thereby cause " white pollution ", and the Poly Foam goods are raw material with the oil, the waste petroleum resources.Starch-based product uses grain resource, under China's grain situation in short supply, should not promote the use of.Paper products are wasted the forest reserves owing to use wood pulp, and cost is very high, and produce the serious environmental pollution in paper-making process.
In order to overcome above-mentioned shortcoming, the invention provides snack container and food container that a kind of crop stalk, rice husk are made, can degraded in occurring in nature 48 hours, the product that is decomposed is free from environmental pollution, and soil fertility can be increased, after this product is reclaimed pulverizing, animal feed and senior crop fertilizer can be made, nontoxic, tasteless, acid and alkali-resistance, corrosion-resistant, high-low temperature resistant, cost be low, be fit to suitability for industrialized production.
It is as follows to finish the technical measures that task of the present invention takes:
It consists of prescription of the present invention by weight percentage:
Straw, powdered rice hulls 61.55～66.67, edible sodium carboxymethylcellulose 2.22～6.25, powdered whiting 4.45～11.53, polyurethane 0.74～3.12, surplus is a water, spray covering surfaces with polyurethane lacquer so that product can acid and alkali-resistance, corrosion-resistant, high-low temperature resistant, the polyurethane lacquer consumption is for only covering product surface.
Fig. 1 is the making flow chart of product of the present invention.
The processing method of product of the present invention comprises that the following step poly-:
(1) according to the above ratio sodium carboxymethylcellulose, polyurethane and water are added in the beater Be heated to 50～100 ℃ of making beating 10～40 minutes;
(2) slurry is poured in the mixer, again straw, rice husk are pulverized with high speed disintegrator Becoming the above powder of 150 orders and powdered whiting to add in the mixer stirred 25～35 fens Clock becomes the dough shape;
(3) take out material group and put into six roller tablet press breaking down compressing tablets, cut out with tablet press machine rear portion hobboing cutter Become just base, finished product has certain surplus relatively;
(4) extrusion modling in 45～100T hydraulic molding machine is sent in the tablet press machine waste product and clout back to breaking down compressing tablet again, to cut the waste;
(5) through micro-wave oven flash baking to curing molding;
(6) the tunnel of 60～150 ℃ of temperature sections kiln drying 30～40 minutes;
(7) air-cooled to room temperature to reduce the varnish adsorbance;
(8) with the spraying of polyurethane lacquer single face, avoid the etch of water with the protection product surface;
(9) under 80～150 ℃ of temperature dry 30～40 minutes;
(10) spray another side with polyurethane lacquer;
(11) under 80～150 ℃ of temperature dry 30～40 minutes, the products obtained therefrom water content was by weight≤2%;
(12) air-cooled to room temperature, with convenient check workman operation;
(13) desk checking outward appearance;
(14) packing;
(15) sterilization is valid for one year;
(16) warehouse-in;
