Description

Manufacturing method of nano shell powder plastic ingot

Technical field

The invention relates to a method for preparing a nano-shell powder plastic ingot.

Background technique

In ancient times, technology was limited, and cement was not a popular item. It was forced to use local oyster shells as a binder for building materials. At that time, Taiwan, China, was used as a binder for building materials from the Dutch rule to the Japanese rule in the 17th century. Artificial calcination burns oyster shells into oyster ash, and then uses oyster ash to blend sugar water and glutinous rice syrup to become an adhesive. The traditional brick and stone combination is used. This proves that oyster ash is an indispensable and important building material in the past. In addition, in the construction and maintenance of old wooden boats, oyster ash mixed with tung oil must also be used to fill the crevices of the wooden boat so that it will not leak water, and it has both strong and durable characteristics.

Today, low-cost industrially produced cement and plasticized raw materials have completely replaced oyster ash, making oyster shells useless. As a result, fresh oyster production areas have piles of unmanageable oyster shells, causing serious local problems. As a result, the civilians are forced to think about solutions in Taiwan, but after research by private units and institutions, there are many results in the conversion of oyster shells:

One. Fertilizer: Because oyster shells are rich in minerals and calcium carbonate, the oyster shells are crushed and then evenly sprinkled in the farmland and stirred to neutralize alkalinity and become a fertilizer for soil improvement. Fruits will also put oyster flour to add nutrients.

Second, feed: if the oyster shells are ground into coarse grains, they can be supplied in chicken and duck feed, so that the chickens and ducks can be used as a basis for supplementing minerals and calcium carbonate after eating, and the eggs laid by the chickens and ducks will not be softened and cracked problem.

Third, food: If the oyster shell is ground into powder, it can be used as food for humans to provide nutrients for the body to supplement the minerals and calcium carbonate.

Fourth, the greening of the saline zone: The saline zone contains the seaside. In this area, oyster shells can be laid first, and then light soil can be laid on the oyster shells. The oyster shells can only be dialyzed into the light soil with moisture upwards. It completely prevents the salt from rising into the light soil. According to this, it is guaranteed that the light soil can be planted with green plants, flowers and trees that cannot withstand salt.

Continuing from the use of ancient oyster shells and the current research results, the results have better greening effects in fertilizer, feed, food and salt areas. In the application of sea wool yarn and thermal insulation of industrialized fibers, the technology still has to be settled or agglomerated, and the current industrial application is limited to the fiber, which actually wastes the antistatic and antistatic properties of the calcined oyster shell. The effect of ultraviolet rays, therefore, thinking about how to re-use and highlight the value of oyster shells is already the first research center for industrialized applications.
