Process for improving viscosity of attapulgite clay

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 non-metallic ore processing technology, in particular to a processing technology for increasing the viscosity of attapulgite clay. Background technique:

[0002] Attapulgite clay, also known as palygorskite or palygorskite, is a hydrous magnesium-rich silicate clay mineral with chain layer structure. Attapulgite clay has high plasticity in the presence of water, good stability in high temperature and salt water, and low density, generally 2.05-2.30g / cm 2 , hardness 2 to 3 (Mohs hardness).

[0003] Due to the unique crystal structure of attapulgite, it has many special physical, chemical and technological properties, and has become 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.

Embodiment Construction

[0021] Below in conjunction with embodiment the present invention will be further described:

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

[0023] 2. Modification treatment:

[0024] ①Take 97% of attapulgite clay after natural weathering, add 3% sodium carbonate evenly, and input it into the immersion pool together, add clear water for immersion aging, and the immersion time is 96 hours.

[0025] ② Take the soaked attapulgite clay, put it into the mixer for stirring, and extrude the stirred attapulgite clay into thin slices through an extruder, and the thickness is controlled at 1.0 mm.

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