Embodiment Construction

[0021] The present invention will be further described in conjunction with the following examples:

[0022] 1. Natural weathering: From the attapulgite clay mined in the mining area, the viscosity of the attapulgite clay is 1800mPa·s. After 80 days of natural weathering, the viscosity is 1880mPa·s, which is higher than that of the freshly mined attapulgite clay. The viscosity increased by 4.44%.

[0023] 2. Modification treatment:,

[0024] ① Take 97% of the naturally weathered attapulgite clay, evenly add 3% sodium carbonate, and put them into the soaking tank together, add clear water for soaking and aging, soaking time is 96 hours.

[0025] ②Take the soaked attapulgite clay, input it into a mixer for mixing, and squeeze the agitated attapulgite clay into thin slices by an extruder, with the thickness controlled at 1.0 mm.

[0026] ③The attapulgite clay flakes are air-dried, and the water content of the attapulgite clay flakes after air-drying is ≤ 15%.

[0027] After the modifi...

Abstract

The invention discloses a jprocess for improving viscosity of attapulgite clay which comprises the steps of modification treatment, batching, agitating, milling and detect. The process can be applied into the real processing procedure of Attapulgite clay, and can increase the viscosity of the end product by over 35%.

Description

Technical field: [0001] The invention relates to a processing technique of non-metallic minerals, in particular to a processing technique for increasing the viscosity of attapulgite clay. Background technique: [0002] Attapulgite clay, also known as palygorskite or palygorskite, is a water-containing magnesium-rich silicate clay mineral with a chain-layered structure. Attapulgite clay has high plasticity in the case of water, good stability in high temperature and salt water, and low density, generally 2.05~2.30g / cm 3 , Hardness 2~3 (Mohs hardness). [0003] Due to the unique crystal structure of attapulgite, it has many special physicochemical and technological properties, making it one of the clay minerals with wide application and high economic value. Attapulgite clay is mainly used in water purification, adhesives, pesticide carriers, molecular sieves, desiccants, adsorbents, coatings, mud, activated clay, foundry sand and chemical industries. [0004] The attapulgite clay d...
