Abstract

The invention relates to the technical field of active clay, in particular to an active clay acid reducer, which comprises the following components in percentage by weight: 36-66% of SiO2, 5.0-20% ofAl2O3, 0.5-12% of Fe2O3, 0.2-10% of MgO, 0.2-10% of CaO, 0.1-4.0% of K2O, 0.1-15% of TiO2, 0.1-5% of Na2O, the balance is inevitable impurity, the PH value is >=7. The invention can not only prepare the activated clay finished product which conforms to the national standard or the activated clay finished product which is specified by the customer, but also can increase the output of the activatedclay and improve the economic benefit of the enterprise.

Description

technical field [0001] The invention relates to the technical field of activated clay, in particular to an activated clay acid reducer. Background technique [0002] Activated clay is an adsorption decolorizing agent made of clay (mainly bentonite) as raw material, treated with inorganic acid or salt or other impurities, rinsed with water, and dried. The appearance is powdery, odorless, tasteless, and non-toxic. , strong adsorption performance, can adsorb colored substances, organic substances, widely used in petroleum, chemical, food, national defense or medical and other fields. [0003] The production techniques of activated clay mainly include suspension method (wet method), aging method (wet method), extrusion method (semi-dry method), ultrasonic and microwave method (dry method). The production process of full dry method and semi-wet method is difficult to operate, and the stability of product quality is poor, which limits the use of activated clay, and is rarely used...
