Embodiment Construction

[0027] Below in conjunction with embodiment the present invention will be further described:

[0028] 1. The sodiumized chlorite ingredients are composed of the following components by weight percentage: chlorite flakes 95.6%, instant sodium silicate 2.1%, polyvinyl alcohol 1.6%, hydroxypropyl methylcellulose 0.5% and sodium acid pyrophosphate 0.2%.

[0029] 2. The production method of sodiumized chlorite: input the sodiumized chlorite ingredients into the mill for grinding, the particle fineness is ≤0.074 mm, and the powder after grinding is sodiumized chlorite stone.

[0030] 3. The production method of chlorite flakes: (1) input the chlorite mixture into the immersion tank, then slowly add water into the chlorite mixture for soaking and sodiumization, and the soaking time for sodiumization is 48 hours; (2) take out the soaked The chlorite mixture is stirred in a double-shaft mixer, and after being evenly stirred, it is input into an extruder and extruded into chlorite fla...

Abstract

The invention discloses sodium modified chlorite, and the key points of the technical scheme are that: sodium modified chlorite ingredients comprise chlorite, magnesium oxide, sodium carbonate, instant sodium silicate, polyvinyl alcohol, hydroxypropyl methyl cellulose and sodium acid pyrophosphate. A production method of the sodium modified chlorite is as follows: sodium modified chlorite ingredients are transported into a mill for powder milling, and the milled powder is the sodium modified chlorite. By first sodium modification and then ingredient compounding, chemical reaction of the sodium carbonate and the instant sodium silicate, the polyvinyl alcohol and the hydroxypropyl methyl cellulose can be avoided. According to the needs of product quality, the sodium acid pyrophosphate is used for adjusting the PH of the sodium modified chlorite. The sodium modified chlorite has the characteristics of good adsorption, suspension property, thixotropy, lubricity and thermal stability and high plasticity, and is applicable to the production of filler, sorbents, suspending agents and lubricants for asphalt felts, paper making, pesticides and fire control products.

Description

technical field [0001] The invention relates to sodium treatment, in particular to a sodium-treated chlorite. Background technique [0002] Chlorite is a kind of aluminosilicate mineral, which often coexists with authigenic quartz. It is in the shape of needles, pompoms, and roses. Its occurrence in the pores is pore lining and pore filling. Generally, the coniferous chlorites are mostly pore liners wrapped on the surface of the particles, while the pompom-like and rose-like ones are filled in the pores. Chlorite can be transformed from minerals such as biotite, hornblende, and montmorillonite. Authigenic chlorite is generally rich in high-valent iron ions, and it is easy to produce precipitation when it interacts with HCL and other acids in drilling fluids, causing reservoir damage. , is an acid-sensitive mineral. [0003] In the chlorite mining area, excavators are used for mechanized mining of chlorite raw ore, and what is excavated is a dense massive chlorite raw ore, ...
