Broad Application Prospects of Magnesium Oxide for Glass Fiber Reinforced Plastic

In recent years, due to the driving force of domestic and foreign two markets in China, glass fiber reinforced plastic industry has got rapid development. Meanwhile, its downstream of the magnesium oxide industry, also going into a high-speed development period. But many manufacturers said, researching and developing of high-end magnesium oxide environmental protection material have broad prospects.

It is important for magnesium oxide to being used in glass fiber reinforced plastic production, such as the roles of thickener and increase the FRP brightness. So, compared with same type, the glass fiber reinforced plastic added magnesium oxide are welcomed by the markets. What is worth mentioning, not all types of magnesium oxide can be added to the glass fiber reinforced plastic, only special magnesium oxide can reach the ideal effect. MEISHEN magnesium oxide supplier can custom-made specifications by different customers requirements. In general case, we need to adjust the activity of magnesium oxide according to the change of climate. As for magnesium oxide for glass fiber reinforced plastic, it is better to choose active magnesium oxide, even more, it is better to choose higher activity of magnesium oxide for winter, and choose low activity magnesium oxide for summer.

Compared Magnesium Hydroxide with Aluminum Hydroxide

Both magnesium hydroxide and aluminum hydroxide are the most important inorganic flame retardants. Their common characteristics are environment friendly, filling, smoke suppression and have flame retardant function. Aluminum hydroxide is one of the earliest inorganic flame retardant in time, having the features of no corrosive gas, good stability, flame retardant effect lasting, non-toxic, etc. Otherwise, magnesium hydroxide is one of the inorganic flame retardants currently in actively research and development at home and abroad, based on the advantages of aluminum hydroxide in the above, it is better than aluminum hydroxide in smoke suppression performance and thermal stability. Heat absorption capacity of magnesium hydroxide is higher than aluminum hydroxide 17%, more beneficial to improve the flame retardant efficiency. In summary, different flame retardants have different characteristics and USES.

Compared with aluminum hydroxide, the advantages of magnesium hydroxide as follows:

1.The thermal decomposition temperature of magnesium hydroxide is 330 ℃, higher than aluminum hydroxide 100 ℃, which is more conducive to improve the processing temperature, extrusion speed, shorten the molding time.

2.Magnesium hydroxide with acid have a strong neutralizing ability, can neutralize acid gases quickly in the progress of high polymer burning, such as CO2, NOX, SO2 and so on.

3.Magnesium hydroxide has high resolution capability, helping to absorb the heat of combustion, and improve the flame retardant efficiency.

4.Magnesium hydroxide has small hardness and strong smoke suppression ability. What is more, it has weak frictional force for equipment, and helps to prolong the lifetime.

The activity is an important factor to measure the quality of magnesium oxide. As one of the main inorganic activator, adding little magnesium oxide can improve sulfidity of rubber greatly. In rubber industry, magnesium oxide and zinc oxide are playing the roles of liquidity and antioxidant ability, and optimizing the tensile strength and impact resistance of the rubber. Therefore, magnesium oxide is one of the important compound of halogenated rubber.

In chloroprene rubber production, magnesium oxide and zinc oxide are mixture and used as vulcanizing agent, in this way, magnesium oxide can reduce the activity of zinc oxide, then have the effect on slowing down the vulcanization rate, to avoid appear the problem of early crosslinking. Meanwhile, magnesium oxide can also have the effect of acid acceptor, and prevent the charred and cyclization, usually added at the beginning of the mixing. Secondly, the activity of magnesium oxide, that is to say iodine absorption value, has an big influence on scorch resistance performance of CR, even more, has a certain influence on modulus, tensile strength and hardness.

Talk More about the Loss On Lgnition

In magnesium oxide specifications, there are six commonly used physical and chemical indicators. Loss on lgnition is one of it, which has several features that other specifications like silicon, calcium, iron, aluminum cannot be compared.

The first, controllability. That is to say, after mineral being put into the furnace, we can adjust the content of it by control the calcination of calorific value and the sintering time. Therefore, you can more easily to control magnesium oxide products required different by ignition loss.

The second, the relationship with the ratio of magnesium oxide. The content of silicon, calcium, iron, aluminum are determined by ore, loss on lgnition is different from it, and inversely proportional to the content of MGO. For example, the kind of magnesium oxide 93%, that is meaning, the content of loss on lgnition is 7%, then directly calculate the magnesium oxide content is 86%. If the content of loss on lgnition increased 2% by storage or other reasons, the content of magnesium must fall off 2%.

The third, the coagulation time of magnesium oxide products. Under certain conditions, the coagulation time of magnesium oxide is particularly fast, sometimes it is opposite, even appear not-solidification phenomenon. In this case, you can look for reasons from two aspects, the one is operating temperature, the other one is loss on lgnition.

In conclusion, the higher content of loss on lgnition of magnesium oxide, the faster solidification rate.

Tips for Magnesium Oxide Suppliers to Ensure Profit Maximization

With the change of market environment, market competition is becoming more and more fierce. In this case, magnesium oxide supplier need to pay attention to the ways and methods on the premise of guarantee profits. There are some tips for magnesium oxide suppliers to ensure profit maximization.

1.Make brand famous.
Magnesium oxide supplier need to attach great importance to brand power. Only do the best products quality and service, can make MEISHEN brand into people’s heart, and become the first and required choice. Famous brand can meet customers’ changing requirement, and supply custom-made, after-sale technical guidance, even returning and exchanging. Do better in service and quality, rather than lower price.

2.To be unique.
Magnesium oxide suppliers need to research new promotion methods to attract more consumers, especially for magnesium oxide, which has a longer service life, simply to explain product performance and advantages can not meet the customers’ requirements. Suppliers should consider the specific difference in application, as well as other related products, so as to meet the customized needs.

3.Improvement of service.
Put consumers in the first place. No matter customer want to consult or buy products, we must show respect, smile to meet, patience interpretation, leave a good impression to consumers. Meanwhile, magnesium oxide suppliers are also need to strengthen our own business training and after-sales service quality, once appear problem, should help customers solve problems as soon as possible. Magnesium oxide suppliers as the basis of market forces, plays a great role in the whole market operation.

Important Uses of Magnesium Oxide in Rubber Industry

Activity is the important indicators to measuring the quality of magnesium oxide for rubber industry. In the rubber production, active magnesium oxide as one of the important inorganic activator, only add a small amount can greatly improve the degree of vulcanization.

You have to know, magnesium oxide, the same with zinc oxide are playing the role of liquidity and antioxidant ability, optimizing the tensile strength and impact resistance of the rubber. So they are the important compounds of halogenated rubber. In CR, magnesium oxide and zinc oxide mix as a curing agent, then magnesium oxide can reduce the activity of zinc oxide, to have the effect on slow down the vulcanization rate, in order to avoid crosslinking problems in the early time. Meanwhile, magnesium oxide can also have the effect of acid acceptor, to prevent the charred and cyclization. Secondly, the activity of magnesium oxide, that is iodine adsorption value, have a big influence on scorch resistance performance, tensility, tensile strength and hardness.

In addition, light magnesium oxide is also the frequently-used kind in rubber production. Most of the time, it plays the same role with active magnesium oxide. In conclusion, magnesium oxide plays an important role in rubber industry.
