Manufacturing methods
Water-soluble acrylamide-acrylate emulsion copolymer is a main material of acrylamide and acrylate, made by copolymerization reaction and special treatment of
water-soluble emulsion
.

Physical and chemical properties

Solubility: soluble in water.
Density of emulsion is 1.0g/cm
3
. High flash point, it does not belong to
dangerous chemicals
.

The main purpose
Mainly used as fluid loss control agent for oil (gas) drilling fluid, good compatibility with other drilling fluid additives, applied to all kinds of water base drilling fluid. But used with caution in high-density drilling fluid. When used, it can effectively control the API fluid loss of drilling fluid and improve the quality and
lubricity
of mud cake.

Use
Water-soluble acrylamide-acrylate emulsion copolymer is a water emulsion. When used, product should be mixed drilling fluid directly, adopting uniform slow addition method or intermittent addition method. In addition, the dosage of the product should be determined according to the drilling fluid formulation. Recommended addition level of it is 0.5% to 1.0%.

Storage matters
1 package Logo: Water-soluble acrylamide-acrylate emulsion copolymer is packaged with blue plastic barreel. Its net weight is 200kg. 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: Water-soluble acrylamide-acrylate emulsion copolymer 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.

Acceptance criteria
In the factory, Products were tested by our quality supervision departments to ensure that products meet quality standards or contract the corresponding standards. Users have the right to correspond to the standard of the quality of the products received acceptance. If any, should be made within one month of receipt of product, coordinate and solve the supply and demand sides. If more than one third batch of products have been used, we have the right to refuse to retest.
