Embodiment Construction
[0029] Below in conjunction with embodiment the present invention will be further described:
[0030] 1. The acidified loess ingredients are composed of the following components by weight percentage: 96.5% of acidified loess semi-finished products, 1.5% of instant sodium silicate, 1.4% of polyvinyl alcohol, 0.58% of hydroxypropyl methylcellulose and 0.02% of sodium carbonate %.
[0031] 2. The production method of the acidified loess: input the acidified loess ingredients into the mill for grinding, the particle fineness is ≤0.074 mm, and the powder after grinding is the finished product of the acidified loess.
[0032] 3. The production method of acidified loess semi-finished products: (1) Input the ingredients of loess mixture into the running mixer and stir, then slowly add dilute sulfuric acid into the loess mixture for acidification treatment; (2) Pass the acidified loess mixture through the rollers Machine extruded into loess flakes, the thickness of the loess flakes is...

Abstract
The invention discloses acidized loess. According to the technical scheme, ingredients of the acidized loess comprise loess, attapulgite clay, magnesium oxide, sulfuric acid, soluble sodium silicate, polyvinyl alcohol, hydroxypropyl methyl cellulose and sodium carbonate. The ingredients of the acidized loess are conveyed into a mill to be milled into powder, wherein the powdery material obtained after milling is the acidized loess. According to the production method of the acidized loess, the sulfuric acid can be prevented from having chemical reactions with the soluble sodium silicate, the polyvinyl alcohol, the hydroxypropyl methyl cellulose and the sodium carbonate; after the loess is acidized, the pH value is controlled within the range from 5.5 to 7.5, and therefore the utilization ratio of the loess can be increased, good economic benefits, environmental benefits and social benefits can be brought, and the purpose of making waste profitable can be achieved. The acidized loess is good in adsorbability, thixotropy, thermostability, plasticity and cohesiveness and suitable for producing environmental protection materials, garden materials, building materials, foaming agents and fire protection products.
Description
technical field [0001] The invention relates to acidification treatment, in particular to acidified loess. Background technique [0002] Loess is a special soil formed under arid climate conditions, generally light yellow, grayish yellow or yellowish brown, with large pores and vertical joints visible to the eye. It is now generally believed that it is mainly deposited by wind, often calcareous and often contains shells, bones and mammalian teeth, as well as calcium carbonate nodules, and sometimes iron oxide nodules to form high-quality soil that can store a large amount of water. [0003] The mineral composition of loess has three types: detrital minerals, clay minerals and authigenic minerals. Detrital minerals are mainly quartz, feldspar and mica, accounting for 80% of detrital minerals, followed by pyroxene, hornblende, epidote, chlorite, magnetite, etc.; in addition, the carbonate mineral content in loess More, mainly calcite. Clay minerals are mainly illite, montmo...
