1.To guarantee products with good gas yield,we take a lot of sampling test during carbide processing.
2. To guarantee carbide drums seal tightly and safety,we do regular air pressure test to drums.
3. To avoid size-mixing,we store different sizes separately.
4. To guarantee loaded goods with correct weight,sizes gas yield and guantity,we take sampling test again when loading carbide to containers.

1. Use the high quality of sodium formate as raw material.
2. Keep sodium formate and sulphoacid (purity 60%) as a proportion of 1:2.1 to guarantee the formic acid good purity but no crystallization.
3. To gurantee the quality of the formic acid liquid at light yellow colour by controling the temperature at 50℃ .
4. To control the reaction time at 45 Min to gurantee the liquid quality.
5. Seal up , keep in dry and cool place.
