Microsilica as a commonly used mineral admixture for concrete, can effectively improve the strength of concrete, but also can be added to refractory materials to improve its wear resistance, but many people will find that a lot of microsilica will appear damp caking phenomenon, which affects the use, then microsilica caking how to deal with it?
The cause of microsilica moisture caking
Microsilica damp caking, that must be inseparable from the moisture in the storage environment, when there is damp caking, that can only mean that there is a problem with the storage of microsilica, and did not pay attention to the causes of this situation are the following:
- The storage environment is relatively humid, ventilation is not enough, even if there are bags to hold, in a humid environment, there will still be moisture through the gaps in the packaging into the internal, thus mixing with the microsilica, to be dried after the formation of lumps.
- Microsilica can not be stored in direct sunlight or high temperature, because direct sunlight or high temperature, will make the microsilica packaging aging phenomenon, aging bags can not effectively block the moisture in the air, the same will make the microsilica moisture caking;.
- Microsilica packaging is crude in addition to the environment, more fundamental reasons, many manufacturers in order to reduce the cost, will use very crude packaging bags, resulting in sealing is not tight enough, it is easy to moisture entry and aging phenomenon, so the purchase of microsilica must choose a reliable manufacturer.
The microsilica caking how to deal with
Microsilica clumping is very affected by its performance, and even in some humid conditions will produce mold, affecting the health of the user, so to prevent moisture clumping is very important thing, but if there has been a moisture clumping phenomenon, it needs to be handled according to different circumstances.
- If the microsilica is found to be damp, but the degree is light, and there is no clumping, the damp products should be dried in a timely manner, and in the case of confirmation of no deterioration and decay priority use off, and then check the other microsilica one by one and deal with the damp factors in a timely manner.
- If the microsilica has appeared lumpy phenomenon, it means that it has been damp and dried, then you need to ensure that no other mold, and make it completely dissolved before use, and other microsilica that has not yet appeared damp re-check, replace the storage environment.
How to prevent microsilica moisture caking
The first thing to do is to choose a reliable microsilica powder manufacturer, such as Henan Superior Abrasives.
In addition to packaging, should also provide a proprietary storage site for the storage of microsilica, the first is to avoid a humid environment, because the humid environment can not guarantee whether the moisture in the air with corrosive, damaging the product packaging, but also should avoid direct sunlight and high temperature environment.
Want to prevent microsilica moisture caking, should also pay attention to the product transportation process, the process to avoid being bumped, to stop sharp objects cut the bag, while in the product stacking, should also pay attention to lightly placed, not throw, fall, smash. In order to meet the needs of different customers, Henan Superior Abrasives can produce microsilica powder products with different specifications and usage requirements.
