What is Sodium Metasilicate?

Salt metasilicate is quickly soluble in water, insoluble in alcohol and acid, and also liquid option It is alkaline, simple to soak up wetness and also deliquescence when positioned airborne, has descaling, emulsification, dispersion, dampening, leaks in the structure and also buffering ability to pH value, and is provided by the nation as “fine chemicals with concern advancement in China” as well as “inorganic chemicals in China in the future”. Among the bottom lines in the development of chemical items. Sodium metasilicate is a low-molecular crystal produced by the hydrothermal reaction of average frothing soda and also caustic soda. The industrial items consist of anhydrous, pentahydrate as well as nonahydrate, of which nonahydrate is only readily available in the Chinese market Presence is an emergency situation item with low technological material that was established quickly in the 1980s when sodium metasilicate was urgently required. Due to the fact that its melting point is only 42 ° C, crystal water will certainly be released at 30-40 ° C, which brings inconvenience to use., It is very easy to become liquid or paste when stored, as well as it is slowly being eliminated. Nonetheless, because of some user practices and some fields are not really concerned about crystal water, sodium metasilicate nonahydrate still has a specific market.

Amongst the not natural electrolytes, sodium metasilicate has the best active alkalinity and also PH buffering index, has a solid feature of wetting, emulsifying as well as saponifying oil, has exceptional performance in getting rid of, spreading out and putting on hold dust, as well as can protect against dust It can reduce the effects of acidic dust, emulsify fats as well as oils, have anti-flocculation effect on inorganic materials, and anti-corrosion effect on steels. It can change salt tripolyphosphate in Synthesize high-efficiency detergent and also steel cleaning agent to lower the air pollution of salt tripolyphosphate to the environment. Salt metasilicate has actually been put on cleaning agents for more than 40 years abroad, as well as the application modern technology is relatively mature; it has actually been related to cleaning agents as well as other markets for greater than twenty years in China. It is a fully grown chemical product. At the same time, it also has a fully grown and also wide market. Sodium metasilicate has a multitude of applications in commercial areas such as detergent, porcelains, electroplating, textile, printing and also dyeing, papermaking, concrete, concrete, refractory materials, oil as well as natural leather processing. Today, the order of sectors with large applications is: ceramics, industrial cleansing, detergents, concrete, printing as well as dyeing, papermaking, concrete, oil expedition, and also others.

Sodium Metasilicate Uses

1. Salt Metasilicate is commonly made use of in various cleaning industries. In the washing sector, such as super-concentrated washing powder, laundry detergent, washing lotion, dry cleaner, fiber whitening agent, material whitening agent, and so on, it is likewise widely utilized in steel surface cleaning representatives, beer containers, floating item solvent cleaner, all-soluble Ultimately, it can be made use of as a metal antirust representative, range cleaner, and also electrical tool cleaner, and can be used as a detergent in the food market.

2. It can additionally be made use of as mud consistency regulatory authority as well as mud decoagulant in crude oil as well as all-natural drilling control mining engineering.

3. Sodium Metasilicate In the construction market, it is used as a coagulant for preparing acid-resistant mortar, acid-resistant commercial concrete and also concrete.

4. In the paper market, it can be utilized as an adhesive, ink agent, as well as paper surface therapy representative.

5. Sodium Metasilicate is made use of as a printing and dyeing auxiliaries and also material pretreatment representative in the fabric sector.

6. Salt Metasilicate can likewise be utilized as soap filler, cleaning agent, egg chemical, as well as vegetation molecular filter, silicic acid and fire resistant materials.

Sodium metasilicate has lubricity and also can be utilized in the production of ceramic body mud; it has solid alkalinity, solid purification capability, huge buffering ability, and can counteract acidic dust. It emulsifies fat as well as oil, has anti-flocculation result on inorganic compounds, and has anti-corrosion effect on metals. As a result, it is just one of the primary parts in super-concentrated cleaning powder, and also it is also utilized in dishwashing detergents, food industry cleaning agents, as well as metal detergents. And also waste paper deinking, etc.

Preparation Method of Salt Metasilicate

The methods commonly used at present to prepare Salt Metasilicate can have two kinds of dry production with molten equimolar amounts of sodium carbonate and silicon dioxide and wet production with liquid sodium hydroxide heating and pressurizing to dissolve silicon dioxide.

In the Chinese patent document whose publication number is CN 1153139A, a kind of natural potassium feldspar is also reported as a raw material, after pulverization, batching, roasting, pressurized water immersion, filtration, concentration and countercurrent spray drying, then through compaction, Calcination changes the crystal form and many other steps to obtain powdery anhydrous sodium metasilicate. The method has more steps and a longer route. In addition, Chinese patent documents such as CN1188741A and CN1223232A have also reported methods for preparing sodium metasilicate pentahydrate and sodium metasilicate nonahydrate using sodium silicate and sodium hydroxide as raw materials.

A preparation method of granular Salt Metasilicate, using sodium silicate as a raw material, measuring the modulus of its aqueous solution and adjusting its modulus to 0.99-1.04 with sodium hydroxide, heating and concentrating at a temperature lower than the boiling point of the solution to a weight concentration of After 50%-55%, it is sprayed through a nozzle with a diameter of 2.0-2.5 mm at a pressure of 80-90 kg/cm2, and is sprayed and dried in countercurrent with hot air. The inlet temperature of the hot air for drying is 340°C-350°C. The temperature is 80°C-90°C.

Content Analysis of Salt Metasilicate

Weigh 1g sample of silicon dioxide correctly, placed it into a beaker, acidify it with 5ml hydrochloric acid, vaporize to dry skin on the steam bath, include 5ml hydrochloric acid and repeat the operation as soon as, blend the deposit with 1ml hydrochloric acid and 2ml water, placed it in the steam bath Hydrolyze until soluble salt is gotten, filter with ash-free filter paper, laundry with warm water, transfer to a platinum crucible, dry at 105 ° C for 1 hour, and carbonize at a lower temperature. Then burn at 1000 ° C to continuous weight. Moisten the residue with a few decreases of water, include 15ml of hydrofluoric acid and also 5 drops of 1:3 sulfuric acid, drive off the acid on a heating plate, and then shed at 1000 ° C to continuous weight. Salt oxide Precisely consider 500 mg of the example, disperse it in 150 ml of water, as well as warm up until completely dissolved. Include 2-3 drops of phenolphthalein examination solution (TS-167) and 100.0 ml of 0.1 mol/L sulfuric acid. Usage 0.1 mol/L salt hydroxide to drop to pink, and also after the two are deducted, every milliliter of 0.1 mol/L sulfuric acid stage.
