Beyond its impact on physical performance, glycyl glutamine also plays a role in supporting the immune system
. Glutamine is considered a vital nutrient for immune cells, particularly lymphocytes and macrophages, which are essential for the body’s defense mechanisms. Under stress, such as strenuous exercise or illness, the body’s glutamine levels can deplete, leading to impaired immune function....

- Overall, rock drilling tools play a vital role in various industries and are essential for the successful completion of drilling operations. By choosing the right tools and ensuring their proper maintenance, companies can improve the efficiency and cost-effectiveness of their drilling projects.
- Coal drilling is not a task for the faint-hearted, nor is it a job that can be accomplished without the right equipment. It demands robust, high-performance drill bits that can withstand the harsh conditions of the earth's crust and the abrasive nature of coal. The primary function of a coal drill bit is to penetrate the rock layers, creating boreholes for blasting or inserting mining machinery.
- 2. Improved Efficiency The unique design of MF rock drill rod allows for increased drilling speed and efficiency. The rod is designed to transfer power more effectively, reducing the amount of time and effort required to complete a drilling job.





Extended Life
The coated resin surface increases resistance to chemical corrosion and continuous UV exposure.

Hengshui Jrain, completed a lot of FRP fittings for our Australia customer, and they were loaded from workshop today. Hope their travel oversea is joyful.
Fiberglass reinforced plastic (FRP) is a composite material made of a polymer matrix reinforced with glass fibers. This material is often referred to as glass fiber reinforced plastic or GRP (Glass Fiber Reinforced Plastic).


Jrain’s products can be designed and manufactured specially based on customer’s specific application.


Due to the hard carbon nanofibers and abundant welded joints among the nanofibers, the hard carbon aerogels display robust and stable mechanical performances, including super-elasticity, high strength, extremely fast recovery speed (860 mm s-1) and low energy loss coefficient (<0.16). After tested under 50 % strain for 104 cycles, the carbon aerogel shows only 2 % plastic deformation, and retained 93 % original stress.
