basic concepts of cellulose ether In dry mortar, the addition of cellulose ether is very low, but it can significantly improve the performance of wet mortar, which is a major additive that affects the performance of mortar construction. The cellulose ether is mainly made of natural fiber, and is processed by alkali dissolution, graft reaction(etherification),.. read more →

Acidifiers are mainly designed for weaned piglets as feed additive to compensate for lack of gastric acid in stomach. The research of acidifiers has a history of over 40 years. In 1960, people in feed industry found that piglet diarrhea can be relieved by organic acid. After that, simple acidifiers were used to lower pH.. read more →

Set-Accelerator refers to an additive, which can increase the mortar strength and has no significant effect on the later strength. According to the chemical composition, it is divided into two types: organic and inorganic.The organic includes Calcium Formate , Triethanolamine, Triisopropanolamine, Urea, etc. And the inorganic includes Sulfate, Chloride and so on. The effect of.. read more →

Effect of fumaric acid, calcium formate and mineral levels in diets on the intake and growth performance of newly weaned pigs The weaned pig has limited ability to acidify its stomach contents. The objective of this study (comprising three experiments) was to examine the effect of feeding diets containing fumaric acid (FA), calcium formate (CF).. read more →

Effects of dietary calcium formate inclusion on broiler performance Modern broilers grow much faster and more efficiently than their predecessors. Because of the rapid growth rates of broilers, particular attention must be given to the skeletal development of the bird. Calcium formate (CaFo) has been used as a calcium source in animal diets in the.. read more →

As the main product or the by-product, calcium formate has various production methods. The main method for producing calcium formate at present is to react with dilute formic acid and calcium carbonate or calcium hydroxide to generate calcium formate solution. After the insolubles are filtered out, and the filtrate is concentrated and crystallized. Then calcium.. read more →

In drying mixed building materials, such as thermal mortar, ceramic tile adhesive, cement base plaster, repair mortar, waterproof mortar and etc, in order to increase their early strength, usually high alumina cement and gypsum are used as coagulants. Antifreeze should be added under low temperature environment, calcium formate as a new type of setting-Accelerator has.. read more →

Eggs are the main source of income for laying hens. Unlike broiler chickens, the main topic of raising laying hens is to improve the quality of eggs and maintain or increase the production of eggs, not to improve the quality of chicken. The shell of an egg accounts for 12% of the total weight of.. read more →
