Abstract
The invention discloses a technique for rapidly and efficiently improving the viscosity of attapulgite clay by adopting a pure physical method. The technique is suitable for all the attapulgite clay and the newly-mined attapulgite clay needs no mound for weathering and can be used for treatment. The key technical points are that: the attapulgite clay is soaked, repeatedly extruded for a second time, watered, frozen, heated and crashed to obtain a finished product. The viscosity of the attapulgite clay processed by the technology is 2-8 times of original soil.
Description
Technical field
The invention belongs to nonmetalliferous ore deep processing field, be specifically related to the technology that the pure physical method of a kind of usefulness rapidly and efficiently improves viscous of attapulgite.
Background technology
Attapulgite (being called for short recessed soil down) is a kind of silicate of rich magnesium, and crystalline structure belongs to 2: 1 type layer chain clay minerals.Structure that recessed soil is special and character are given its very high using value, make it obtain widespread use at aspects such as purification of water quality, binding agent, farm chemical carrier, molecular sieve, siccative, sorbent material, coating, drilling muds.The colloidal property that recessed soil is good is that recessed soil is used one of most important performance, but the brilliant Shu Shifen that the excellent crystal fiber body in the natural recessed native mineral forms is fine and close firmly, even the particulate that is crushed to below 0.1 millimeter also is difficult to homodisperse in dispersion medium, thereby limited the performance of recessed native colloidal property to a great extent.Viscosity is the important indicator of products such as recessed soil preparation drilling mud, anti-settling agent and binding agent, also is the important evidence of this type of recessed native produce grade classification.
Improve recessed native viscosity at present and mainly reach by adding the collaborative corresponding physical treatment process of activator or tackifier modification, pure physical method yet there are no report.Chinese patent " technique for producing high-viscosity adhesive ' Aotu ' soil " (publication number CN1187461), disclose " the present invention relates to a kind of technique for producing high-viscosity adhesive ' Aotu ' soil; it is a raw material with the attapulgite clay ore deposit, through ore dressing, fragmentation, add roll again after activator soaks, dry, pulverize form ".The Chinese patent complete processing of viscosity of attapulgite clay " improve " (publication number CN1317067) disclose that " complete processing of raising viscosity of attapulgite clay is: natural weathering, modification processing, batching, stirring, abrasive dust and detection.Improve the complete processing of viscosity of attapulgite clay, be applied in the actual course of processing of attapulgite clay, the viscosity of its final finished than the viscosity of firm exploitation attapulgite clay, can improve more than 3 5%." above-mentioned two inventions all need be added certain additive modification, and the viscosity of the recessed soil after handling improves not remarkable.
Summary of the invention
The objective of the invention is to: a kind of technology with pure physical method rapidly and high-effectively raising viscous of attapulgite is provided, and the natural characteristic of the recessed soil of this process makes full use strengthens viscosity, abandons the auxiliary agent tackify.
Technical solution of the present invention is: recessed soil is through soaking, repeat secondary extrusion, water mixing, freezing, heat treated after, pulverizing gets product.
The concrete steps of a kind of technology that improves viscous of attapulgite with pure physical method rapidly and high-effectively of the present invention are as follows: step 1 is for soaking, and recessed soil adds in the clear water and soaked 24 hours; Step 2 is extruding for the first time, water mixing, freezing and heating, the recessed soil of step 1 gained drains the water, be squeezed into thin slice through extrusion machine, its gauge control is at 1 millimeter, and recessed soil after the extruding and clear water be 2: 1 ratio thorough mixing by weight, makes thinner, went into the freezer quick freezing 2 hours, temperature of ice house-18 ℃ is gone into baking oven baking 1 hour, oven temperature 50-60 ℃ after the recessed soil after freezing takes out; Step 3 is extruding for the second time, water mixing, freezing and heating, recessed soil after step 2 is smoked and clear water be 4: 1 mixed by weight, go into extrusion machine and be squeezed into thin slice, 1 millimeter of sheet thickness, recessed soil after the extruding and clear water be 2: 1 ratio thorough mixing by weight, makes thinner, went into the freezer quick freezing 2 hours, temperature of ice house-18 ℃, baking oven baking 1 hour, oven temperature 50-60 ℃ are taken out in freezing back; Step 4 for the recessed soil of step 3 after smoking through pulverizer pulverize finished product, finished product granularity≤0.074 millimeter.
The invention has the advantages that: 1, complete processing is simple and easy to do, need not to add any auxiliary agent; 2, immersion and freezing preceding moisture are supplied, and promote water to enter the crystalline substance bundle inner chamber of the various holes, particularly recessed soil of recessed soil by wicking action; When freezing, water freezing causes its volumetric expansion, and the recessed mass of soil grain of disintegration particularly disperses fine and close, the firm excellent brilliant combination of recessed soil-crystalline substance bundle; Be extruded with and help the crystalline substance bundle of recessed soil be separated and tear; The recessed soil that the viscosity ratio of processing recurve soil is newly exploited out improves 2-8 doubly; 3, present method can directly use the new recessed soil of exploiting out to process, and need not to handle through heap Chen Fenghua.
