Embodiment 1

[0036] The specific steps for the application of magnesium oxychloride cement to produce disposable tableware are:

[0037] 1) Dissolve 60 grams of magnesium chloride hexahydrate in 100 grams of water at room temperature. At this time, a small amount of magnesium chloride hexahydrate should be undissolved in the solution to obtain a magnesium chloride solution.

[0038] 2) Weigh 17.5 grams of lightly burned dolomite and 0.3 grams of attapulgite, mix and grind them evenly to obtain powder.

[0039] 3) Mix 4.5ml of magnesium chloride solution with all the powder in step 2), and grind for 10 minutes.

[0040] 4) According to the shape of the tableware, the slurry is formed by conventional extrusion or injection into the tableware mold; the tableware is a plate, cup, bowl, spoon, chopsticks or fork;

[0041] 5) After 40 minutes, demould or cut the tableware, place the tableware for 4 hours, then dry it in a ventilated environment at 60°C for 4 hours, take it out after drying, was...

Abstract

The invention, which relates to application of magnesium oxychloride cement, is characterized in that Magnesium Oxychloride Cement can be applied to disposable tableware, which is recyclable, environment-friendly and good to the health of human body.

Description

technical field [0001] The invention relates to an application of magnesium oxychloride cement. Background technique [0002] The existing magnesium oxychloride cement is mainly used in the construction field. [0003] The current disposable tableware (such as plates, cups, bowls, spoons, chopsticks or forks) is made of wood, paper or polymer materials. Disposable tableware consumes a lot of resources objectively, especially wooden or paper Disposable tableware belongs to one-time consumption, which not only causes waste of wood resources, but also brings pollution to the environment. my country consumes 45 billion pairs of disposable chopsticks and paper tableware every year, consumes 1.66 million cubic meters of wood, and needs to cut down about 25 million large trees, which is equivalent to reducing the forest area by 2 million square meters. At the same time, the use of polymer materials to produce disposable tableware has brought huge pollution to the environment beca...
