First, the use of products
Drilling fluid defoaming agent is drilling mud additives commonly used a chemical reagent, the drilling fluid defoaming agent XPJ- II is the company with be defoaming system developed with silicone (silicone) as the main material, compound many kinds of surface active agent, dispersion agent and osmotic agent and synergistic agent and thickener consisting of defoaming agent, can quickly eliminate foam drilling mud, and long time of antifoam. Its dosage is little, diffusion, good permeability, good heat resistance, chemical stability, high resistance to oxidation, low fluorescence level. No physiological activity, no corrosion, no toxicity, no adverse side effects, non flammable, non explosive, high security. It can be widely used in oil field drilling, well cementing, foam recovery and other aspects, and has a good lubrication effect. Can also be used in wastewater processing, printing and dyeing, paper making, water paint, latex paint, chemical, leather processing, emulsion polymerization, and all kinds of metal cleaning fluid, cutting fluid, grinding liquid, liquid cooling, cleaning agent aqueous system defoaming.

Two, technical requirements

Project	Index
Appearance	Milk yellow to milky white oil
Density，g/cm3	0.8～1.0
pH value	6～7
Recovery rate of drilling fluid density，%	≥80
Fluorescence grade	≤4

Three, the use of methods
Recommended general dosage 0.2%-0.5%, directly added to the bubble system.

Four. Storage and transportation
1 store in a cool, dry, ventilated place, prevent direct sunlight, away from the fire source.
2 transport and handling should be handled gently and prevent violent collision, extrusion, inversion.

Five, matters needing attention
In the use process, the staff shall wear labor protection supplies, to prevent products splashed into the eyes or contact to the skin, once the occurrence of the above phenomenon, immediately wash with plenty of water, in serious cases, timely medical treatment. Sprinkle on the ground should be as far as possible, for a small number of products with soil landfill, you can also use a large amount of water to wash, wash water into the waste water system.
