2 Preparation, structure and chemical properties of synthetic benthic soil
2.1 Preparation of synthetic benthic soil
It is insoluble in water, but can hydrate and expand in water to form a colorless transparent colle. When its mass fraction in the water is 2%, a single synthetic bentoty crystal of highly denatured collosomes can be formed.
the synthesis process of synthetic bentographic soil can be found in Figure 1. Sodium, magnesium and lithium salts are mixed with sodium silicate at a certain speed and temperature to produce non-stereotyped sediments, which are then treated at high temperatures to form part of the crystal. The resulting crystals are filtered, washed, dried and milled, resulting in a delicate white powder.2.2 Structure of synthetic benthic soil
Synthetic bentosic soil has a flaky structure, scattered in water to form flaky crystals, can be regarded as two-dimensional "inormeric polymer", the ideal structure of a single cell in the crystal is shown in Figure 2. The magnesium ions of the six octaphal structures in the figure are sandwiched between two layers of four tetum silicon atoms. These groups are balanced by 20 oxygen atoms and 4 hydrogen-oxygen roots. The height of the cell cell unit determines the thickness of the synthetic benthic crystal. The cell unit is repeated several times in the two-dimensional direction, forming the flaky appearance shown in Figure 2. It is estimated that a typical synthetic bento-earth crystal contains up to 2,000 cell units.2 shows the ideal structure for synthetic benthic soil, with 12 positive charges provided by Mg2 plus in the middle octaeth structure. In fact, unit-price lithium partially replaces magnesium. The resulting emerald chemical structure is: Na-0.7 (Si8Mg5.5Li0.3) O20 (OH)4- 0.7. The surface of synthetic benthic crystals has a negative charge of 50 to 55 mmol/(100 g). The positive charge is generally 4 to 5 mmol/(100 g) because the part of the particle is absorbed with a positive charge. Synthetic benthic soil particle size reached the nanoscale, compared with the traditional natural soil and Han soil, the particle size is much smaller.
2.3 Chemical properties of synthetic benthic soil
static electricity attracts sodium ions from the solution to the crystal surface, while water molecule permeation pressure tends to separate sodium ions. Sodium ions establish a balance in the diffusion zone of the front and back sides of the dispersed synthetic benthic crystals, as shown in Figure 3. As the two crystals approach, their positive charges are mutually exclusive. Dispersions show low viscosity and Newtonian flow.active substances (salts, surfactants, solvents, soluble impurities, pigments, fillers, substrates and additives, etc.) are added to the synthetic bentonish dispersion, which reduces the osmosis pressure that repels sodium ions on the crystal surface, causing the double layer to contract, causing the weak positive charge of the crystal edge belt to interact with the negative charge on the adjacent crystal surface. As the process continues, a "house of cards" structure is formed, and a system of water and salt forms a highly denatured gel (Figure 4). The gel is gathered together by the positive and negative charge attraction of the crystal..
