The main purpose
Mainly used for oil (gas) drilling fluid lubricant compatibility with other drilling fluid additives, good for a variety of water base drilling fluids. In the water base drilling fluid, it has strong anti-foaming and lubricity and is a broad spectrum defoamer. The pollution caused by malignant carbonate has a certain extent.

Use
DEFA is a liquid product. In the course without dissolving, it is easy to use and can be directly mixed with drilling fluid evenly. In addition, the dosage of the product should be determined according to the drilling fluid formulation.
Recommended addition level of it is 0.1% to 0.5%.

Storage matters
1 package Logo:
DEFA is packaged in 208L plastic drum
. Each batch of product quality inspection report should be single. On the packaging, there should be clear, strong logo. Signs include: trademark, name, type, production batch number, net weight and the Health and trade names and so on.
2 Storage: Defoamer for drilling fluid should be stored in ventilated, dry room temperature 5°C to 30°C, and to grant the unit separately. Keep away from fire sources, avoid strength extruded and sunlight exposure. Co-exist with non-corrosive chemicals.
3 Transport: the application of clean means of transport with a tarpaulin, moisture, rain, sun, light textile handling should take to prevent scratch or smashes the packaging.
