Attapulgite argil powder with air purifying function

Abstract

The invention discloses an attapulgite argil powder with an air purifying function. The technical scheme is as follows: the attapulgite argil powder with an air purifying function is prepared from high-viscosity attapulgite clay, an attapulgite constant-humidity conditioner, a natural mineral adsorbing / filtering agent, Cacumen Biotae, aluminum silicate fiber and polyacrylamide. The attapulgite argil powder is prepared by the following steps: pulverizing the materials, soaking and aging to obtain a wet mixture, extruding the wet mixture into a strip, airing the strip, pulverizing to obtain powder, and packaging to obtain the finished product. The attapulgite argil powder has favorable cohesive property, plasticity, thixotropy, fire resistance and thermal stability; the pottery prepared from the attapulgite argil powder with an air purifying function contains a great deal of micropores and activated carbon, thus, has the characteristics of low shrinkage, no cracking or deformation and favorable adsorbability, and can effectively adsorb formaldehyde, ammonia, benzene and other harmful substances in the air, thereby protecting the environment and improving good health of people. The invention is suitable for producing pottery artware with an air purifying function.

Description

technical field [0001] The invention relates to pottery clay, in particular to an attapulgite pottery clay powder with the function of purifying air. Background technique [0002] The mineral composition of clay raw materials is complex, mainly composed of kaolinite, hydromuscovite, montmorillonite, quartz and feldspar, the particle size is inconsistent, and often contains sand, silt and yellow clay. [0003] The color of pottery clay is yellowish-brown, off-white, reddish-purple and other hues. The pottery clay is water-absorbent and plastic after adding water. [0004] The texture of pottery fired with clay is relatively loose and has many pores, so it has strong water absorption. However, the body of pottery made of ordinary clay has a large shrinkage rate after drying and is prone to cracks. Performance is poor. Contents of the invention [0005] The purpose of the present invention is to overcome the deficiencies in the prior art and provide an attapulgite clay powd...
