| Brief introduction |
Main differences between this product and traditional products are: it has granular physical structure and granular size of 0.074mm ~ 3mm. Comparing with traditional powdery products, it has following advantages:
1. Safety production and better quality: In feeding procedure, this granular product has no problem of dust. This greatly improves working conditions of workers, eliminates powder combustion and explosion hidden dangers resulting from static electricity and meanwhile prevents the problem of pollution from happening.
2. Excellent service performance: during using process, the grain product enables very smooth material feeding, conveying and quantity measurement and is especially suitable for mechanized and automated operation.
3. Good product stability: For greatly decreased grain surface area and cover layer on surface structure of grain, the product stability is significantly enhanced and its moisture absorption time in air is 4 to 6 times longer than powder products.
4. During the process of adding and using, this product may be easily mixed with polyethylene powder. |
