Embodiment 1
[0030] Concretely use a kind of technique that bamboo pulp is provided by the invention to produce pulp molded lunch box:
[0031] 1. The selected raw materials are biennial moso bamboo chips from Chongyi, Jiangxi, with a water content of 10%, and the size of the bamboo chips is 25×10×5mm. The main chemical components are shown in the table below;
[0032] Moso bamboo chemical composition%
[0033]
[0034] 2. In view of the special requirements for sanitary conditions in the production of lunch boxes, the raw materials used are manually selected, large pieces, rotten pieces, impurities and debris are removed, and the pieces are washed in a stainless steel tank;
[0035] 3. Put the washed bamboo slices into the stainless steel dipping tank, and add the liquid medicine in proportion, the amount of NaOH is 8%; after covering the tank cover, directly steam and heat up for dipping, the dipping pressure is normal pressure, and the liquid ratio is 1: 4. The soaking time is 3 hou...

The invention relates to a process for producing a paper pulp molded meal box by using bamboo pulp. The process is characterized by comprising the following steps: S10, selecting raw materials; S20, carrying out material preparation; S30, dipping; S40, grinding the slurry; S50, carrying out slurry treatment; S60, molding; S70, testing the product; and S80, analyzing a result. Compared with other pulp, the bamboo pulp has the advantages of being low in cost, clean and environmentally friendly when being used for producing the molded meal box, and the molded meal box produced from the bamboo can meet the oil-proof performance requirement. In addition, the invention further discloses a preparation system of the natural color bamboo pulp. The production system comprises a bamboo pretreatment unit, a first reaction kettle, a thread rolling machine, an extruding machine, pulping equipment, a second reaction kettle, a defibrator, a latency tank, a dilution tank and a spiral pressure screen which are arranged in sequence. By the adoption of the pulping process and system, low-energy-consumption, pollution-free, clean and environment-friendly pulping can be achieved, the product can be widely used, environmental pollution is avoided, and the recovery cost of the used product is reduced.
Description
technical field [0001] The invention relates to the fields of pulp molding and catering packaging, in particular to a process for producing pulp molding lunch boxes with bamboo pulp. Background technique [0002] At present, most of the disposable lunch boxes are plastic products. The plastic contains a large amount of unstable plasticizers or plasticizers. When encountering hot soup and rice, it will release harmful substances to the human body and affect people's health. In addition, plastic Lunch boxes are difficult to degrade. Plastic lunch boxes are generally discarded as garbage after use. At present, there are no very scientific classification and degradation measures in my country. Generally speaking, they can only be buried or weathered, which will take decades or more than a hundred years. Seriously affect our living environment. Finally, if waste plastic lunch boxes are directly incinerated, it will not only produce a lot of black smoke, but also produce dioxins—the...
