I believe that people engaged in industry or agriculture must be familiar with calcium formate, in addition to adding calcium formate to the production of concrete and cement, many people have also begun to put their vision into farming feed. But calcium formate is not easy to use, it also comes in different types and grades. One of the more common is a feed additive, and the other is an early strength agent in building materials. Industrial grade calcium formate is prohibited for the feed industry, so what are the main differences between industrial grade calcium formate and feed grade calcium formate, and how to judge it?
(1) Industrial grade calcium formate
Industrial grade calcium formate is a rapid coagulant, lubricant and early strength agent widely used in the construction industry. Suitable for building mortar and all kinds of concrete, can accelerate the solidification of cement, shorten the setting time, especially in winter construction, can prevent the solidification speed is too slow at low temperatures. To make the early strength of the cement production or use process is improved, and it is more quickly used.
In addition, the industry can also be used for cement, mortar, leather tanning or as a preservative, by-product generally low content, more impurities, poor efficacy, low price.
(2) feed grade calcium formate
It is very useful in the early stages of farming. It is a high-purity, high-content additive and is one of the nationally recognized feed additives.
The main differences between industrial and food grade calcium formate are obvious in many ways:
1. Appearance. The calcium formate for feed is pure white crystal with uniform particle size and good fluidity.
2. Content. Among them, the feed grade calcium formate content and calcium content are determined by a fixed percentage, industrial grade calcium formate relatively more impurities, so the purity is lower than the feed grade. The two can also be classified and distinguished according to the composition of ortho-and ortho-acid.
3. Heavy metals. The heavy metal of feed grade calcium formate is relatively close to 0 or less.
In general, these two types of calcium formate are probably these aspects, we must pay attention not to mix industrial grade calcium formate and feed grade calcium formate together, not only can not play the original role, but also have more difficult results.
