Abstract
The object of this invention is to provide a kind of wilkinite novel sodium base metallization processes, first exploit raw material and screen and dry, pulverize afterwards, after pulverizing, carry out shallow sodium process successively, carry out secondary sodium Multilevel method afterwards and breed, just can obtain finished product.Present invention process is simply effective, drying, having saved the energy without the need to adopting; And through twice sodium, Multilevel method breeds, just can obtain sodium even, the sufficient sodium bentonite of sodium effect, its sodium homogeneity can reach more than 96%.
Description
Technical field
The present invention relates to the manufacture field of natural montmorillonite, particularly relate to a kind of wilkinite novel sodium base metallization processes.
Background technology
Wilkinite take montmorillonite as the nonmetallic minerals of main mineral constituent, because door takes off some positively charged ion of the laminate structure existence that stone structure cell is formed, as Cu, Mg, Na, K etc., the effect of these positively charged ions and montmorillonite structure cell is very unstable, easily by other cationic exchange, therefore there is good ion exchangeable.Abroad apply in industrial and agricultural production 24 field 100 Duo Ge departments, have more than 300 product, thus people are referred to as " omnipotent soil ".
Bentonitic interlayer cation kind determines bentonitic type, and interlayer cation is Na
+time claim sodium bentonite; Interlayer cation is Ca
2+time claim calcium-base bentonite; Wherein the processing performance of sodium bentonite is better than calcium-base bentonite.But calcium-base bentonite distribution is far wide in sodium bentonite, therefore to carries out modification to calcium-base bentonite exactly except strengthening finding except sodium bentonite, making it to become sodium bentonite.Bentonite sodium metallization processes traditional at present just adds sodium agent after wilkinite crushing, stirring, and to carry out sodium then dry, and such technique sodium is uneven, and effect is insufficient, affects quality product, therefore solves the problem and just seems very necessary.
Summary of the invention
The invention provides a kind of wilkinite novel sodium base metallization processes, the problem such as the sodium solving original technique is uneven, sodium effect is insufficient, this technique sodium homogeneity is high, can meet the demand of different client.
The object of this invention is to provide a kind of wilkinite novel sodium base metallization processes, comprise the following steps:
Step one: exploitation bentonite material, removes large grained thing;
Step 2: raw material is layered on the base of hard field and utilizes sunlight to dry;
Step 3: after drying, carry out pulverization process, crushing process includes stirring, adds sodium carbonate afterwards, has pulverized and will screen, and removes macrobead thing;
Step 4: after pulverizing, evenly sprays sodium carbonate after it being again layered on the base of hard field, sprays the wilkinite that step 3 obtains again, spray one deck sodium carbonate more afterwards, finally breed at least 24h after having sprayed sodium carbonate,
Step 5: after breeding, is drawn in, covers upper film, continues to breed 3-7 days, obtains sodium even, effective sodium bentonite.
Further improvement is: the bentonitic fineness that pulverizing mill grinds is 120 ~ 350 orders, and the moisture finally obtaining finished product sodium bentonite is less than 10%.
Further improvement is: the number of plies of step 4 wilkinite and sodium carbonate also can up add, and its number of plies is minimum is 4 layers.
Further improvement is: the total mass of the sodium carbonate added for twice is limited, can not add, and the sodium carbonate total mass that this technique adds accounts for the 3%-7% of sodium base wilkinite quality.
Beneficial effect of the present invention: the present invention first adopts raw material and dries, pulverizes, carries out once shallow sodium after pulverizing, and the sodium carbonate of the even spray of paving afterwards touches wilkinite again, and present invention process is simply effective, drying, having saved the energy without the need to adopting; And through twice sodium, Multilevel method breeds, just can obtain sodium even, the sufficient sodium bentonite of sodium effect, its sodium homogeneity can to more than 96%.
Embodiment
In order to deepen the understanding of the present invention, below in conjunction with embodiment, the invention will be further described, and this embodiment only for explaining the present invention, does not form limiting the scope of the present invention.
The present embodiment provides a kind of wilkinite novel sodium base metallization processes, comprises the following steps:
Step one: first exploit out wilkinite, screening obtains bentonite material;
Step 2: paved by bentonite material utilizes sunlight to dry on the base of hard field;
Step 3: after drying, carries out abrasive dust process, and milling process removes macrobead thing along with stirring and screening, adopts sodium machine to add sodium carbonate afterwards and carries out a sodium;
Step 4: after a sodium, is layered on part wilkinite on the base of hard field, evenly sprays sodium carbonate and wilkinite successively afterwards, after breed 24h;
Step 5: after secondary sodium, draws in wilkinite together, covers film, continue to breed 5 days, obtain finished product.
Total number of plies of step 4 wilkinite and sodium carbonate is 4 layers; The bentonitic fineness that pulverizing mill grinds is 200 orders; The moisture finally obtaining finished product sodium bentonite is 9%; The quality that the total mass adding sodium carbonate for twice accounts for whole obtained sodium bentonite is 5%.The present invention first adopts raw material and dries, pulverize, shallow sodium is carried out once after pulverizing, the sodium carbonate of the even spray of paving afterwards touches wilkinite again, and like this through twice sodium, Multilevel method breeds, just sodium can be obtained even, the sufficient sodium bentonite of sodium effect, its sodium homogeneity can reach 96%, can meet the demand of different client.
Claims (5)
1. a bentonite sodium base metallization processes, is characterized in that: comprise the following steps:
Step one: from the bentonite ore exploitation wilkinite that calcic base is more, screening obtains bentonite material;
Step 2: the wilkinite paver of exploitation is paved and to dry on the base of hard field;
Step 3: drawn in together by the wilkinite gathering machine dried, be transported to pulverizing mill afterwards and carry out crushing, stirring process, screen afterwards, obtain Powdered bentonite, adopts sodium machine in wilkinite, add sodium carbonate stirring afterwards and carries out the shallow sodium of one-level;
Step 4: the Powdered bentonite crossed through the shallow sodium of one-level is spread out and put on paver on the base of hard field again, evenly sprays one deck sodium carbonate with duster, the Powdered bentonite and sodium carbonate that more evenly spray that the shallow sodium of one deck one-level crosses again, post inoculation at least 24h;
