Tricalcium phosphate for feed is widely used as a phosphate fertilizer. Because phosphorus feed is a new type of feed, many people do not understand tricalcium phosphate for feed. Under such circumstances, if you buy blindly, you will not use it, which will lead to a series of serious consequences. This article will describe in detail the specific knowledge of tricalcium phosphate for feed.

Introduction of tricalcium phosphate
Tricalcium phosphate (abbreviation: TCP) is also known as calcium phosphate. Chemical formula Ca3(PO4)2. White crystal or amorphous powder. There are many crystal transformations, which are mainly divided into low temperature β phase (β-TCP) and high temperature α phase (α-TCP), phase transition temperature is 1120 ° C - 1170 ° C, melting point 1670 ° C; soluble in acid, insoluble in water and Ethanol.
Calcined by superphosphate, defluorinated, desulfurized, cooled, pulverized, and sieved to 180 mesh to obtain tricalcium phosphate for feed.
In the process of production, processing and use, calcium phosphate powder can enter the respiratory tract, and its occupational hazard depends on the impurities silica and fluorine. According to relevant reports, phosphate can cause systemic toxic effects only in large doses, and the dose under normal production conditions is not dangerous.
This product is not flammable.
Calcium salts are incompatible with tetracycline antibiotics. Calcium phosphate is incompatible with vitamin E (but not tocopheryl succinate). Calcium phosphate can affect the absorption of vitamin D and form a slightly soluble phosphate with some hormones.
First aid measures
Skin contact: Remove contaminated clothing and rinse with running water.
Eye contact: Lift eyelids and rinse with running water or saline. Seek medical attention.
Inhalation: Remove from the site to fresh air. If breathing is difficult, give oxygen. Seek medical attention.
Ingestion: Drink plenty of warm water and induce vomiting. Seek medical attention.
Emergency treatment: Isolation of contaminated areas and restrictions on access. It is recommended that emergency personnel wear a dust mask (full face mask) and wear general work clothes. Avoid dusting, carefully sweep it, and place it in a bag and transfer it to a safe place. If there is a lot of leakage, cover it with plastic cloth and canvas. Collected for recycling or transported to a waste disposal site for disposal.
Handling precautions: Closed operation, pay attention to ventilation. Operators must be specially trained to strictly follow the operating procedures. Operators are advised to wear self-priming filter dust masks. Avoid dust. Avoid contact with acids. Lightly load and unload during handling to prevent damage to the package. Equipped with leakage emergency treatment equipment. Empty containers may be harmful residues.
Storage Precautions: Store in a cool, ventilated warehouse. Keep away from fire and heat. Should be stored separately from the acid, avoid mixing. The storage area should be provided with suitable materials to contain spills.
Side effects
Since tricalcium phosphate is an amorphous powder, avoid contact with skin and eyes as it can irritate the eyes, respiratory system and skin.
In the process of production, processing and use, calcium phosphate powder can enter the respiratory tract, and its occupational hazard depends on the impurities silica and fluorine. According to relevant reports, phosphate can cause systemic toxic effects only in large doses, and the dose under normal production conditions is not dangerous.
If inadvertently contacted, treat it as follows: 1. Skin contact: Remove contaminated clothing and rinse with running water; 2. Eye contact: Lift eyelids and rinse with running water or saline. Seek medical attention; 3. Inhalation: Remove from the scene to fresh air. If breathing is difficult, give oxygen. Seek medical attention; 4. Ingestion: Drink plenty of warm water and induce vomiting. Seek medical attention.
The above is the introduction of tricalcium phosphate for feed. If you understand the use of tricalcium phosphate feed, you can not harm yourself when you use it. Otherwise, it is easy to cause accidents and cause damage to the body. This is not worth the candle. Be aware that although tricalcium phosphate for feed is easy to use, the body is more important.
