Method for coating high-strength potassium titanate whisker with nano calcium carbonate and alkali matrix of high-strength potassium titanate whisker

Abstract

The invention provides a method for coating a high-strength potassium titanate whisker with nano calcium carbonate. The method comprises the following steps: (1) firstly, preparing the high-strength potassium titanate whisker; (2) mixing the potassium titanate whisker with a reacting agent, introducing CO2 of which the purity is 95% or higher, and performing heating stirring for 1-1.2 hours; and (3) filtering a reactant, washing, and drying, thereby obtaining the potassium titanate whisker of which the surface is coated with nano calcium carbonate. The invention further discloses an alkali matrix which comprises the following components in parts by weight: 5-10 parts of the potassium titanate whisker of which the surface is coated with nano calcium carbonate, 20-30 parts of improved organic matters, 5-15 parts of alkalescence matrixes, 4-5 parts of alkaline soil bacteria and 1-2 parts of a soil conditioning agent.

Description

technical field [0001] The invention relates to the field of material technology, in particular to a method for coating nano-calcium carbonate with high-strength potassium titanate whiskers and an alkaline matrix thereof. Background technique [0002] Under the conditions of different pH values ​​of sandy fluvo-aquic soil and loamy fluvo-aquic soil, the pH value of the root system of peanut seedling stage and the growth of seedlings were tested. It is acidic, and the root pH values ​​of different varieties in the same pH environment and the same variety in different pH environments are different. Within the range of pH values ​​set in the experiment, the growth of peanut seedlings is the largest at pH 7-8. [0003] In addition, studies have shown that the combination of nano-calcium carbonate, humic acid and organic fertilizer can promote tillering of peanuts, increase the number of effective needles, leaf area and dry weight, and increase the soluble sugar and protein conte...
