Abstract
The invention relates to a method for dispersing the deposited particles of ferruginous cemented mud rock so as to accurately test the particle size of the mud rock. The method comprises the following steps of: grinding mud rock to particles with certain sizes, adding excessive hydrochloric acid to remove ferric oxide, and grinding to disperse the deposited particles in the tightly and firmly solidified mud rock by using a rubber grinding stick.
Description
Affiliated technical field
The present invention relates to the glued mud stone testing graininess of a kind of irony new method, particularly can test the granularity of the glued mud stone of irony of fixed very consolidation, can be widely used in the glued sediment of irony.The dispersed deposition particle of size fractionated especially is provided in geological research.
Background technology
All unusual consolidations that the glued mud stone of irony is general fixed.And irony wherein; A part is the original hole stuff (promptly deposition-the stage of giving birth to together generates) that from solution, are precipitated out simultaneously with detrital grain; Another part is that iron-bearing mineral is constantly decomposed by pore water in the Diagn process; Discharge, the iron oxide that is produced bonds together deposited particles tightly, is very difficult to separately.To the sample of fixed diagenesis, generally adopt the micro-image method to carry out sreen analysis, but mud stone is made up of the clay and the detrital grain of superfine little (the main part particle diameter is generally less than 50 microns), be difficult to analyze size value with image method.And other sreen analysis method all is to the discrete particles sample.
Summary of the invention
In order to analyze the glued mud stone granularity of irony, the invention provides a kind of method of mud stone particle dispersion that irony is glued, obtain granularity data thereby can analyze accurately.
The technical solution adopted for the present invention to solve the technical problems is: iron oxide and hydrochloric acid reaction can form iron chloride soluble in water, make in the mud stone particle separately.Mud stone is crushed to a certain size particle; Add excessive concentrated hydrochloric acid, soak certain hour, wash acid; Adding a certain amount of oxydol again removes organic; Clean the pouring in the porcelain mortar of particle milled gently, can obtain the mudstone sample of particle dispersion, add water and spreading agent and can use laser particle analyzer to carry out testing graininess.
The invention has the beneficial effects as follows; Mud stone is crushed under certain particle diameter handles sample, neither influence the initial size of deposited particles, again can be effectively the iron-holder of the glued mud stone of irony be reduced to below 0.1%; It is loose that deposited particles is able to, thereby guaranteed testing graininess result's accuracy.And the method is simple, and is easy to operate.
Embodiment
At first use iron mortar, mud stone is ground to diameter 1 millimeter, sieving keeps the particle of diameter 0.8-1.2 millimeter.Then sample is put into glass beaker and add excessive concentrated hydrochloric acid, soaked 12 hours, and intermittently stir, it is fully reacted.Three, hydro-extractor is centrifugal, rotating speed: 3000 rev/mins, and the time: 15 minutes.Go to the upper strata to add deionized water after the stillness of night again, stir, left standstill 1 hour, centrifugal once more, remove supernatant liquor.Four, add 20% excess hydrogen peroxide solution, boiled 5 minutes, stirring is fully reacted it, and is centrifugal, removes supernatant liquor.Five, sample is poured in the porcelain mortar, added small amount of deionized water, use glue to grind hammer particle is milled gently, fine grinding is about more than 30 minutes.Turbid solution is poured in the beaker, and ultrasonic oscillation is 20 minutes under 40 KHzs.Add deionized water and spreading agent, can use laser particle analyzer test granularity.
