Abstract
The method for reducing ceramic radioactivity is characterized by adding lead-containing raw material or lead-containing clinker clue in the ceramic blank material, in which the content of added lead-containing raw material or lead-containing clinker clue is less than 10% of total content of said ceramic blank material. On the premise of that the whiteness and internal sintering property of ceramic product are not affected. Said invention can utilize reduction of radioactivity of ceramics material to make it meet new state quality standard so as to attain the goal of protecting health and environment.
Description
Technical field
The present invention relates to a kind of Production of Ceramics preparation method, especially relate to the ceramic radioactive preparation method of a kind of reduction.
Background technology
Because existing building ceramics contains radioactive substances such as zirconium silicate, hypothermia grait usually, therefore existing architectural pottery contains certain radioactivity usually.In order to protect environment and human health, country has newly issued quality testing standard---" the radioactive material nucleic is limited the quantity of ".According to the requirement of this standard, its radioactivity category level must indicate in constructional ornamental material manufacturing enterprise in its packing of product or specification sheets.And, forbid selling the product that does not meet this national standard on the building materials market from July 1st, 2002.And on the existing building materials market, ceramic tile class, particularly albescent ceramic tile class, its radioactivity of nearly 1/4～1/3 product exceed standard, and promptly do not meet new national standard.A large amount of uses of this class ceramic tile will be not only to all producing extremely harmful influence now but also to human health and environment protection in the future.
Summary of the invention
Technical problem to be solved by this invention is: under the prerequisite at coking property in the outward appearance whiteness that guarantees pottery reaches, how to reduce the radioactivity of ceramic product, and make it meet new national quality testing standard.
The present invention is that to solve the problems of the technologies described above the technical scheme that is adopted be a kind of new Production of Ceramics preparation method.This method is plumbiferous raw material of admixture or a plumbiferous frit in ceramic batch, wherein the raw material containing lead of admixture or contain the total content that lead frit accounts for ceramic batch and be no more than 10%.
Evidence: heavy metal lead is the most effective and the most practical material of absorbing material radioactivity.And the present invention adopted in ceramic batch admixture raw material containing lead or contained the preparation method of lead frit, thereby fundamentally solved the higher technical problem of stupalith radioactivity.The present invention makes it meet new national quality testing standard by reducing ceramic radioactive method---and " the radioactive material nucleic is limited the quantity of ", thus progressively realize the human final fine ideal of green home, healthy life, High Quality Environment.Also show by enforcement of the present invention simultaneously: this inventive method is simple, easy to operate, effect is remarkable.
Embodiment
Below in conjunction with two embodiment the present invention is further described in detail.
Embodiment 1 is admixture white lead 1% in ceramic batch.
Embodiment 2 is admixture food lead frit 2% in ceramic batch, and wherein this content that contains plumbous oxide in the lead frit is 60%.
Claims (2)
1, the ceramic radioactive preparation method of a kind of reduction is characterized in that plumbiferous raw material of admixture or plumbiferous frit in ceramic batch.
2, the ceramic radioactive preparation method of a kind of reduction according to claim 1 is characterized in that the raw material containing lead of admixture or contains the total content that lead frit accounts for ceramic batch being no more than 10%.
