DY-024
Dayong
Introduction
This product is a graft copolymer of humic acid salt and cationic components. The introduction of cationic components improves the anti-slump and fluid loss reduction effects of the treatment agent.
Skills requirement:
Project | Index | |
Appearance | Black powder | |
Moisture, % | ≤10.0 | |
PH value (1% aqueous solution) | 8.0～10.0 | |
Screen allowance (sieve aperture 0.90 mm), % | ≤10.0 | |
Viscosity reduction rate | Room temperature, % | ≥70.0 |
After aging at 180 ℃/16 h, % | ≥60.0 | |
API Fluid Loss Reduction Rate | Room temperature, % | ≥50.0 |
After aging at 180 ℃/16 h, % | ≥40.0 | |
High temperature and high pressure filter loss reduction rate (150 ℃/3.5 MPa), % | ≥50.0 | |
Relative expansion rate, % | ≤60.0 | |

Package
The product should be packaged with a three-in-one package as the outer layer and a plastic bag as the inner layer. The inner and outer seals of the package should be bundled separately, and the package should have sufficient strength.
The net mass of each bag of product packaging is (25±0.25) kg.
In each batch of products, 40 bags are randomly inspected, and the average value of each bag shall not be less thanto 25 kg.
Transportation
During transportation, the product should avoid sunlight exposure, moisture-proof, rain-proof, and prevent the packaging bag from being damaged.
Storage
The product should be stored in a ventilated and dry place, and should not be exposed to moisture, rain or sunlight.
Product shelf life is 18 months.
If it exceeds the shelf life, it needs to be re-inspected before it can be used.
