Magnesium Chloride Application
Magnesium chloride is widly used in various industries and normal life. List below for reference:
Magnesium Chloride Desiccant
Magnesium chloride is widly used as the main raw material of desiccant, compared with other desiccant products, it has particular advantages:
1. Its moisture absorption speed is faster, its absorption speed is several times that of ordinary silica gel desiccant. And its moisture absorption rate is high.
2. As a desiccant, magnesium chloride can work a longer time than other desiccants.
3. Magnesium chloride desiccant has chemical hygroscopic properties, it reacts with the moisture to form another substance. It does not release moisture into air as other desiccants when outer circumstance humidity is low. In addition, as long as there is moisture in the air, magnesium chloride desiccant will capture and absorb it, so it can create a dry environment, which is vital for industries with strict humidity requirements.
4. A wonderful character of Magnesium chloride desiccant is that it can keep solid form after absorbing moisture, it does not spill liquid, and do not have any impact for packaging materials, which is much safer and save a lot of trouble.
5. If use magnesium chloride pellet as a desiccant, it can be more favorable.
Snow and Ice melter
The use of rock salt or sand on icy roads has now decreased and is being replaced with magnesium chloride liquor, Magnesium chloride is much less toxic to plant life surrounding highways and airports and is less corrosive to concrete and steel (and other iron alloys) than sodium chloride. The liquid magnesium chloride is sprayed on dry pavements prior to precipitation or wet pavement prior to freezing temperatures in the winter months to prevent snow and ice from adhering and bonding to the roadway. The application of anti-icers is utilised in an effort to improve highway safety. Magnesium chloride is also sold for household and business use to de-ice pavements & driveways. In these applications, the compound is applied after precipitation has fallen or ice has formed, instead of previously. The use of magnesium chloride seems to show an improvement in driving conditions during and after freezing precipitation.
Dust suppression
Due to the hygroscopic character of magnesium chloride, it can be a very effective dust suppressant. Main applications in this field: dust control on gravel roads, rural roads, indoor horse-riding arenas, quarries and mine sites. Since magnesium chloride continuously absorbs moisture from the air, surfaces treated with magnesium chloride stay dust free over a long period of time. Magnesium chloride is not only an excellent dust suppressant, it also acts as a compaction agent. The moisture absorbed from the air binds the dust particles into the road surface. The road traffic then helps the binding process and this results in a stabilised, hard packed road surface. In most cases only one or two liquid treatments per year are required and because it is a 100% natural product, it is non-toxic and safe to the environment
Water treatment
Magnesium Chloride can used as a magnesium source for phosphate removal in waste water (i.e. manure, municipal water treatment, waste water treatments of food processing industry). The phosphate can be precipitated by producing Magnesium Ammonium Phosphate. Magnesium chloride can also be used in combination with calcium hydroxide in non-sulfate containing waste streams. By adding magnesium chloride & calcium hydroxide, magnesium hydroxide is formed in-situ and contaminants (metals or organics) co-precipitate. In this way, process water can be re-used.
Food Industry
As an important coagulant used in the preparation of tofu from soy milk; the pharmaceutical grade is recommended for use in baby foods & nutritional supplements
Animal feed
Used as a source of magnesium nutrition, catalysers, salts for sea aquariums (pharmaceutical grade is often recommended for this end use)
Construction
Used in combination with magnesium oxide for the production of special types of magnesium oxychloride cements (often called Sorel cements). Floors of Sorel cement are very hard, durable and always level as well as having very good conductivity properties (hence suitable for high tech production halls, warehouses) and are resistant to oil and solvents.
Abrasive
Magnesium chloride cements (often called Sorel cements) are used in the production of abrasive stones, polishing marble & granite and in the production of mill- stones (for rice whitening mills)
Household & Cleaning
Used to prevent wet sponges & sponge cloths from drying in packaging; toilet-bowl cleaners, liquid detergents and also as a raw material for production of magnesium silicate, a bleaching stabiliser for washing powders (prevents damage to fabrics by uncontrolled bleaching); as a thickener in some fabric softeners and due to its very hygroscopic character, magnesium chloride can be used as a moisture absorbent to lower the humidity in household rooms.
Textiles
Magnesium chloride can be used as a catalyst in the so-called “finishing” process (cotton & polyester-cotton impregnated with resin preventing creases & folds).
Toiletries
Be used in bath-salt preparations and dermal cosmetics
