Water-soluble anionic shell powder and production process thereof

Abstract

The invention discloses water-soluble anionic shell powder, which is prepared from the following raw materials: 100 parts of shell powder, 30 parts of aluminum oxide and 40 parts of titanium dioxide.A production process of the water-soluble anionic shell powder comprises the following steps: (1) calcining: collecting the discarded shells at the seaside or in vegetable markets, washing, and putting the washed shells into a calciner, and calcining for 1.5 hours at 900 DEG C; (2) cooling: naturally cooling the calcined shells to 40 DEG C, then crushing the shells with a pulverizer, and grindingthe crushed shell into fine powder by using a grinding bowl or a grinder; (3) screening for the first time: screening the ground shell fine powder with a 200-mesh sieve to obtain shell powder; (4) mixing: taking 100 parts of the shell powder, adding 30 parts of the aluminum oxide and 40 parts of the titanium dioxide, and uniformly mixing to obtain a mixture; (5) screening for the second time: screening the mixture obtained in the step (4) with a 100-mesh sieve, and packaging to obtain the finished product. The water-soluble anionic shell powder has a remarkable effect on degradation of toxic substances such as free formaldehyde and benzene.

Description

technical field [0001] The invention relates to shell powder and a production process thereof, in particular to a water-soluble negative ion shell powder and a production process thereof. Background technique [0002] Free formaldehyde, in layman's terms, is that a large amount of formaldehyde is needed as a carrier in the production process of panels, furniture, coatings, and adhesives. However, in the high-temperature production line, most of the formaldehyde has already formed glue and is no longer formaldehyde. , This kind of formaldehyde that has reacted is no longer harmful to the human body. During the production process, a small part of formaldehyde does not participate in the reaction and becomes free formaldehyde. [0003] Free formaldehyde can irritate people's eyes, throat, chest cavity, etc. Long-term inhalation will destroy some tissues of the human body and reduce the immunity of the human body. Formaldehyde is a highly toxic substance. The impact of formal...

Problems solved by technology

The existing products for degrading toxic substances such as free formaldehyde and benzene are not effective. Therefore, developing a water-soluble negative ion shell powder that degrades toxic substances such as free formaldehyde and benzene has become a problem to be solved urgently by those skilled in the art.
