Abstract
The invention discloses a kind of preparation processes of modified conch meal, it is desirable to provide a kind of calcium hydroxide content height, lightweight, porous modified conch meal.The present invention the following steps are included: A. shell cleaning;B. the calcining of shell;C. the modification of shell;The grinding of D shell;E packed products.The present invention is applied to the technical field of new material.
Description
Technical field
The present invention relates to a kind of new material, in particular to a kind of preparation process of modified conch meal.
Background technique
Conch meal is the powder of shell, and 95% main component is calcium carbonate, and there are also a small amount of other organic matters, extensively
Be applied to animal and fowl fodder and food calcium source additive, ornaments processing, construction material, desiccant etc., traditional conch meal is because of it
Manufacturing process is simple, does not play its calcium carbonate content height, porous feature.
Summary of the invention
The technical problem to be solved by the present invention is to overcome the deficiencies of the prior art and provide a kind of system of modified conch meal
Standby technique, has solved the problems mentioned above in the background art.
The technical scheme adopted by the invention is that: the present invention the following steps are included:
A. the cleaning of shell: choosing clean shell and add it to and impregnate 2-10h in the citric acid of 2-10%, and then sand is washed, husky
It is cleaned up, is dried with clear water after washing, be ground into fritter;
B. the calcining of shell: the shell of dried and crushed is put into refractory container, is then placed in calcining furnace, calcination temperature control
At 900-1200 DEG C, calcination time 2-5h;
C. the modification of shell: the shell calcined is put into pressure furnace, and the temperature of pressure furnace is controlled at 500-800 DEG C, then
Vapor and nitrogen are injected into pressure furnace, high pressure furnace pressure is controlled and is modified in 7-13 atmospheric pressure, when modified
Between be 3-6h;
D. the shell being modified is ground, obtains modified conch meal;
E. finished product is vacuum-packed in ground modification conch meal.
Preferably, the shell in the step A is chosen for the low and clean shell of content of beary metal.
Preferably, the pressure in the pressure furnace in the step C is controlled in 10 atmospheric pressure.
Preferably, the grinding shells fineness in the step D is 1500-2500 mesh.
Preferably, the grinding shells fineness in the step D is 2000 mesh.
Preferably, the vacuum packaging finished product in the step E is that ground modification conch meal is packed into vacuum packaging bag
In.
The beneficial effects of the present invention are: since the present invention includes the following steps the cleaning of A. shell;B. the calcining of shell;C.
The modification of shell;The grinding of D shell;E packed products.So the present invention be by selecting pollution-free, clean shell as raw material,
It by high-temperature calcination, being then modified again by pressure furnace high temperature and pressure, to increase containing for calcium hydroxide in conch meal
Amount, increases the hole and specific surface area of conch meal, obtains a kind of calcium hydroxide content and reaches 96% or more, lightweight, porous modification
Conch meal.
Specific embodiment
In the present embodiment, the present invention include the following steps are included:
A. the cleaning of shell: choosing clean shell and add it to and impregnate 2-10h in the citric acid of 2-10%, and then sand is washed, husky
It is cleaned up, is dried with clear water after washing, be ground into fritter;
B. the calcining of shell: the shell of dried and crushed is put into refractory container, is then placed in calcining furnace, calcination temperature control
At 900-1200 DEG C, calcination time 2-5h;
C. the modification of shell: the shell calcined is put into pressure furnace, and the temperature of pressure furnace is controlled at 500-800 DEG C, then
Vapor and nitrogen are injected into pressure furnace, high pressure furnace pressure is controlled and is modified in 10 atm highers, it is modified
Time is 3-6h;
D. the shell being modified is ground, obtains modified conch meal;
E. finished product is vacuum-packed in ground modification conch meal.
In the present embodiment, the shell in the step A is chosen for the low and clean shell of content of beary metal.
In the present embodiment, it is converted to calcium oxide by calcined shell in the step B, by the step C
High pressure is modified, and calcium oxide is reacted with water generates calcium hydroxide, chemical equation are as follows: CaO+H2O=Ca(OH)2, thus significantly
Increase the content of calcium hydroxide in shell.
In the present embodiment, the grinding shells fineness in the step D is 2000 mesh or so.
In the present embodiment, the vacuum packaging finished product in the step E is that ground modification conch meal is packed into vacuum
In packaging bag, this step can prevent from being reacted with Carbon Dioxide in Air and water and keeping modified conch meal rotten.
The present invention, by calcining furnace high-temperature calcination, then passes through height by selecting pollution-free, clean shell for raw material again
Pressure furnace high temperature and pressure is modified, to increase the content of calcium hydroxide in conch meal, increase the hole of conch meal and compare table
Area obtains a kind of calcium hydroxide content and reaches 96% or more, lightweight, porous modified conch meal.
The present invention is applied to the technical field of new material.
Although the embodiment of the present invention is described with practical solution, the limit to meaning of the present invention is not constituted
It makes, for those skilled in the art, is all to the modification of its embodiment and with the combination of other schemes according to this specification
Obviously.
