How To Distinguish And Distinguish Calcium Formate
Nov 22, 2021
Due to the single raw material and simple production process of calcium formate, there are many manufacturers on the market, uneven product quality and price gap. Let's tell you how to distinguish and identify.
1: In normal acid production, 85% pure formic acid and heavy calcium carbonate (after pretreatment, it has high calcium content and less impurities). After a certain time and a certain temperature, calcium formate is more stable, its composition is high, its content is high, and the combination of calcium ions is more stable.
2: In waste acid production, the waste acid used in other products (such as waste acid after leather washing) has low acid content of 20% - 30% and low utilization rate. It also has harmful substances in leather products or other products (such as chloride ion and magnesium ion), low cost and great impact on animal body growth.
3: The by-product calcium formate is the by-product after the main product is generated (such as Methylpropane). In the generation of the main product, raw material formic acid and calcium hydroxide need to be input, in which formic acid reacts with calcium hydroxide to form calcium formate. The by-product of the main product has low content and negligible cost, but the main product (such as Methylpropane) will remain in the by-product calcium formate, It has a great impact on the growth of animals.
How to identify:
1. According to its color, feed grade calcium formate is white crystal with uniform particles, no impurities, glittering and translucent in the sun and strong fluidity.
2. Smell it. Industrial or chemical grade has a strong pungent taste, which will directly affect the palatability of feed, while feed grade has no pungent taste.
3. Taste the taste (touch a little with your finger and put it on your tongue) industrial or chemical grade has large bitterness and astringency, and high content of heavy metals, which directly affects the feeding habits of suckling pigs, while feed grade calcium formate is only slightly bitter, the taste is very light, it melts into the tongue, and then the bitterness disappears. A little light bitterness is a feature of feed grade calcium formate, It will not affect feeding and palatability.
