Active magnesium oxide is one of the important raw material of neoprene adhesive, activity reflects the reaction capacity of magnesium oxide with neoprene adhesive. Generally speaking, Inhale iodine value(mgI2/g MgO) shows the activity of magnesium oxide, Inhale iodine value below 40 (mgI2/g MgO) is low active magnesium oxide, between 40 and 100 is medium active magnesium oxide, more than 100 is called high active magnesium oxide. As a result, high quality of neoprene adhesive general use high active magnesium oxide.
Adhesive is an important species of high yield, wide usage in rubber adhesive. It has the characteristics of: large tack, high bonding strength, flexible rubber, good elasticity, impact-resistant, water, oil, alkali, acid and solvent resistance, ozone resistance, aging resistance, good durability and flame retardancy. It can bond a variety of metals, non-metallic materials, such as used for bonding rubber, leather, fabric, leather, wood, concrete, asbestos and so on. Adhesive include solvent, emulsion type and solvent free three varieties, in which solvent neoprene adhesive is the most widely used. Solvent-based neoprene adhesive is divided into hot and cold-curing type adhesive type, however, currently solvent-based cold bonding adhesive is the most used.
Hebei Meishen Chemical Technology Co.,Ltd is professional in producing all kinds of magnesium oxide, which can be widely used in industrial productions. Magnesium oxide for adhesive have an useful effect on adhesive production, if you are the adhesive manufacture, hope we can help you with our rich experience.

The Procedures in Magnesium Oxide Content Test
Hebei Meishen Chemical Technology Co.,LTD will introduce the procedures in magnesium oxide content Test.
Magnesium oxide legitimate water test
Theoretical basis: Only active magnesium oxide can be reacted with boiling water.
Steps: Accurately weigh 100 grams of magnesium oxide into a constant weight dry beaker, water was added to 400g, so that it is completely wet. Then heating boiling 2 hours on the furnace(Experiments have proved that, at 100 degrees C, two hours of hydration reaction to become fully), at last, take out and drying to constant weight of up to 150 degrees Celsius.
Calculation method: Magnesium oxide content is calculated according to the following formula. The activity of magnesium oxide content = (A – 100) / 45 x 100%. 100 is sample quality before hydration, A is the sample quality after hydration, 45 is a conversion factor.
Explanation:A lot of information is put forward to boil for 45 minutes. Stop the heating time is based on: Turn off electric power, the slurry quickly stop boiling. Because the reaction of magnesium oxide with water is an exothermic reaction, before the reaction is not over, if you stop the heating, the reaction heat will continue to maintain the slurry boiling for some time.
Through a large number of trials, general boil 2 hours response tends to completely. Issues that need attention: the heating process, to avoid spilling a beaker of slurry; drying time is as long as possible to ensure complete evaporation of moisture.

Magnesium Oxide Used in FRP Industry
Magnesium oxide as a kind of chemical additive, playing a very important role of industrial production. Now we will introduce the application in FRP industry.
In FRP industry, magnesium oxide in mainly used as thickeners, curing time modulating agent, brightening agents to enhance. If adding magnesium oxide into FRP production, it can greatly improve the quality, but on the contrary, it is bad for FRP if the magnesium oxide is substandard. Generally speaking, the specification of magnesium oxide need to be custom made, according to the different customer needs. Active magnesium oxide is the choice of most manufacturers.
Warm reminder: as the change of climate, magnesium oxide producers needed to adjust the degree activity. If active degree is higher, then will cause FRP thickening is faster. On the other hand, lower activity will cause the glass fiber reinforced plastic sheet soft, not easy to dry in the process of drying. As a conclusion, in winter, magnesium oxide activity required to be slightly higher, while it will need to be slightly lower in summer. Hebei Meishen Technology Co.,LTD have more than 20 years production experience, hope to have a pleased communication with manufacturers.

What are the Advantages of Nano Magnesium Oxide
Compared with ordinary magnesium oxide products, nano magnesium oxide is welcomed by many industries. It is a new particulate material, appearance is white powder, high purity and large specific area. It is made of very fine grains, non-toxic, odorless, good dispersion. The content of MgO is more than 99.9%, suspended in the water with good performance, easy coating. Nano magnesium oxide is also have a lower hydration rate, and a certain cohesiveness.
Nano magnesium oxide has small particle size, and big surface area. It has high hardness, high purity and high melting point and other characteristics. It has a widely application in electronics, catalysis, ceramics, oil and paint, and other fields. According to different system, add nano powder added amount ranging from 0.1 ~ 0.5%. The user should be based on a different system, after experiments then to determine the best dosage. Another way, you can contact with Hebei Meishen Chemical Technology Co.,LTD to get more information.

Specifications of Magnesium Oxide Industry Application
Magnesium oxide as an important chemical industry additives, there are some specifications needed to pay attention in different industry. Below is our industry production experience for many years, manufacturers can make it as a reference.
1.Adhesive industry. The magnesium oxide content of ferric can not too high, or the adhesive will change colour. Next the content of calcium can not too high, because high content of calcium and screenings will appear statified phenomenon. The activity of magnesium oxide between 120 to 150 is the best, that means, activity too high may due to intense response curve, and it is bad for adhesive products.
2.Tire industry. 90%≤MgO≤95%, the content of MgO can not under 90%. Loss On Lgnition%≤0.5, moisture%≤0.5, have to say, bulk density is also an important specification.
3.Wire & Cable industry. The magnesium oxide content of calcium can not too high, or the Wire & Cable will easily become brittle, even occur leakage and other dangerous situations, those are influence its service life. Moisture content can not too high, or it will occur blister of cable skin. Screenings content decided the Trachoma and Electric Leakage problems.
