Problems solved by technology

[0002] At present, most disposable fast food utensils in China are made of plastic foam as raw materials. The main component of this plastic foam fast food utensils is polypropylene. This polypropylene organic matter cannot be degraded naturally, and it will produce a lot of toxic substances when burned. The environmental pollution is very serious; and when the tableware is heated or greased, it will release pathogenic or even carcinogenic chemical substances, which seriously endanger human health

Embodiment Construction

[0015] Below in conjunction with accompanying drawing and embodiment the present invention is further described:

[0016] see figure 1 , a disposable paper tableware production process, the process steps are: add circulating white water to the hydraulic pulper to 1 / 2 of the volume of the pulper, then start the pulper, and quickly divide the quantitative pulp board into batches Throw it into a pulper for disintegration, and after disintegrating for one minute, add an FDA-certified water repellent and oil repellent, and the whole process of disintegrating the pulp board and adding auxiliary additives is 6 minutes. Then it is sent to the mixing tank to add white water or clear water to make a slurry with a mass concentration of 2‰~2.4‰ of the pulp board. After three stages of desanding to remove impurities and sand, it is placed in the pulping tank. The three-stage desander adopts the model 606 desander to carry out cyclic desanding; the one-stage desander uses a slurry pump wit...

Abstract

The invention relates to a process for producing disposable paper tableware. The process comprises that a raw material of paper pulp sheets is crushed, subjected to hydration forming and hot compression moulding on special moulds and removal of redundant rim charge on a trimming die, examined, sterilized, packaged and made into the finished product of the disposable paper dishware. The process uses widely available natural paper pulp sheets as the raw material. The product of the process is environmentally-friendly and reproducible, has oil and water-proof performance, can be degraded rapidly and naturally after being used and discarded, and causes no harm to human bodies and no pollution to environment. The process has the advantages of simpleness, reasonableness, easy operation and control and safe and reliable operation.

Description

【Technical field】 [0001] The invention belongs to the technical field of disposable paper tableware production, and relates to a production process of disposable paper tableware produced by dehydrating and hot-pressing a special mold after disintegrating a pulp board. 【Background technique】 [0002] At present, most disposable fast food utensils in China are made of plastic foam as raw materials. The main component of this plastic foam fast food utensils is polypropylene. This polypropylene organic matter cannot be degraded naturally, and it will produce a lot of toxic substances when burned. The environmental pollution is very serious; and the tableware made will release pathogenic or even carcinogenic chemical substances when heated or greased, seriously endangering human health. 【Content of invention】 [0003] In order to overcome the above-mentioned shortcomings of the prior art, the present invention provides a kind of pulp board produced by nature as a raw material. ...
