What is Potassium Silicate?

Potassium silicate is also referred to as potassium metasilicate. Separated into three kinds: ① K2SiO3=154.29, anemic crystal, often greenish-green block or lustrous solid. Melting point 976 ℃. Soluble in water, easily soluble in hot water or under pressure. The liquid solution is alkaline and also insoluble in ethanol. When revealed to acid, silicic acid gel is decomposed. Absorbs water as well as deliquesces in the air. ② K2Si2O5=214.37, colorless orthorhombic crystal. Relative thickness 2.456 (25/4 ℃), melting point 1015 ± 10 ℃. ③ K2Si4O9 · H2O=352.56, white orthorhombic crystal. Family member thickness 2.417, disintegrates when heated to 400 ℃. Soluble in water, insoluble in ethanol.

It is created by heat eutectic melting of potassium carbonate or potassium hydroxide and quartz sand. Potassium silicate is hygroscopic and also has a strong alkaline response. Potassium silicate is fairly easy to decompose in an acidic environment and precipitate silica.

Area the crucible in an oven with a temperature level of 200-300 ° C. Afterwards increase the oven temperature to 500-600 ° C. After regular temperature level treatment for 2-3 humans resources, close the stove as well as also wait on the potassium silicate glass semi-finished product. After cooling to space temperature degree in the cooktop as well as likewise taking it out, potassium silicate glass is acquired, which has high purity as well as harmony, an uncomplicated preparation job method, as well as additionally low demands for production tools.

2. Prepare a high modulus potassium silicate not natural nano-resin,
The prep job approach sequentially includes a blending treatment of resources and also a prep work procedure of high-modulus potassium silicate inorganic nano-resin. The blending procedure of resources is to initial include a low-modulus potassium silicate fluid remedy to a mixer, mix to create a vortex, and also later on include water in sequence., silica sol, stabilizer, and additionally integrating representative. After blending similarly, a premade mix is obtained. The prep work procedure of high modulus potassium silicate inorganic nano-resin is to extremely first heat the premade mix to 40 ~ 80 ° C, and then at this temperature degree, after heating The premade combination is flowed as well as likewise reacted in a reaction system developed by a mixer, a flow pump, in addition to a supergravity turning packed bed. Inevitably, the modulus 5.3 ~ 6.2, the solid material 26% ~ 30%, the bit dimension 5 ~ 20nm, as well as the return 98.5 %~ 99% high modulus potassium silicate inorganic nano-resin. The above method not simply improves product premium quality in addition to storage stability, yet also decreases response time and also reduces power usage.

3. Prepare a potassium silicate-based nanocomposite solution,
It consists of the following actions: first usage nanometer potassium silicate treatment as well as likewise nanometer silica sol treatment, include silane coupling representative dropwise, prepare nanometer high modulus potassium silicate alternative, and after that include nanometer natural option to the nanometer high modulus potassium silicate solution. Compound as well as additionally alter the pH value to prepare a potassium silicate-based nanocomposite option. The potassium silicate-based nanocomposite remedy prepared by this technique has great film-forming impact as well as also strong bond.

4. Prepare a potassium silicate reinforcement product,
The reinforcing material is made up of a potassium silicate liquid remedy with a modulus of 3.8-4, a recovery agent, a cross-linking representative in addition to a diffusing representative; its manufacturing strategy is to thin down the low-modulus commercial potassium silicate with water and boost it in a response pot Its modulus reaches 3.8-4. When taking advantage of, thin down the potassium silicate treatment with water, then include an ideal quantity of healing agent as well as cross-linking agent, along with mix uniformly; this dealing with representative can be combed or splashed, and also it is water resistant. The co2 resistance, climate resistance, ultraviolet resistance as well as likewise thermal stability are all above the existing technology. It is easy to use in addition to reduced in expense. At the same time, this reinforcing agent is anemic and also clear.

Potassium Silicate Preparation

A technique for preparing potassium silicate making use of potassium feldspar, that includes the complying with actions:
1) Disintegration of potassium feldspar: Thoroughly mix potash feldspar, ammonium fluoride as well as 98% sulfuric acid according to the mass ratio of 1:1.5 ~ 2.6:1.6 ~ 1.8, respond at 190 ~ 250 ℃ and autogenous pressure, and obtain potassium feldspar. Rock decay deposit and decay gas including SiF4;

2) Gas absorption: The disintegration gas having SiF4 undergoes dust removal treatment, and afterwards an ethanol liquid remedy is used for adsorption to generate fluorosilicic acid as well as silica speeds up; filter and also different to acquire amorphous silica and fluorosilicic acid solutions; this step It consists of presenting the decomposed gas containing SiF4 right into a dirt filter for dirt removal, passing it right into the key and second absorption towers in turn after dust elimination as well as purification, and also absorbing it via an ethanol aqueous solution with a volume portion of 10% to 30% to produce white precipitate as well as Fluorosilicic acid service is centrifuged as well as washed to acquire silica.

3) Leaching of reaction deposit: Make use of a dilute sulfuric acid option with a quantity fraction of 8 to 10% to seep the potassium feldspar decay residue at 90 to 110 ° C, and then filter the leached remedy to acquire a leach remedy;

4) Preparation of potassium fluorosilicate: The leach option goes through cation adsorption therapy to eliminate aluminum ions and iron ions to prepare a potassium sulfate option; according to the stoichiometric partnership, include the potassium sulfate option to the potassium sulfate solution. The fluorosilicic acid liquid generated in the gas absorption step produces potassium fluorosilicate speed up, with an extra of 20% to 100% of fluorosilicic acid. After maturing, it is filtered and also washed with a filter press to obtain potassium fluorosilicate;

5) Prep work of potassium silicate: According to the stoichiometric relationship, hot potassium hydroxide option is included in the potassium fluorosilicate to generate a potassium silicate service having potassium fluoride crystals; for potassium silicate consisting of potassium fluoride crystals, The option is detoxified, as well as potassium fluoride is separated to obtain a potassium silicate option; the potassium silicate option is focused to get a potassium silicate strong.

Compared to the existing technology, those technique of preparing potassium silicate by decaying potassium feldspar primarily uses the potassium aspect as well as silicon element in the potassium feldspar to transform them right into potassium silicate, as well as prepares potassium silicate solid. The spin-off amorphous silica as well as commercial supplies potassium fluoride are acquired; and also in the preparation procedure of potassium silicate, no three wastes are created, low energy intake, high outcome, high recuperation price, constant manufacturing, as well as effective use of potassium feldspar Components are also put to good use.
