High Jetness Injection Black Masterbatch are mainly used for plastic injection, such as PE, PP, ABS, PS so on. This Black Masterbatch has high pigmentation and shiny finish, it could effectively improve the end-products surface shining. The carbon black content is from 40% 55%. High Jetness Injection Balck Masterbatch have shiny pellets surface finishes, the pellets are 2.0mm-4.0mm slice un-regular.

(2) When using, tighten the U-bolt until the wire rope is flattened by 1/3. Because the wire rope is deformed after being subjected to a force, the rope card is to be tightened a second time after the wire rope is subjected to force, so as to ensure the reliability of the joint. If it is necessary to check whether the rope card is slipping after the wire rope is under stress, an additional safety rope card can be used. The safety rope card is installed about 500mm away from the last rope card, and the rope head is released out of a safety bend and then clamped with the main rope so that if the clip slides, the safety bend will be straightened, so that it can be easily found and reinforced in time. .
(3) The spacing between the rope cards is generally about 6 to 7 times the diameter of the rope, and the rope cards should be arranged side by side. The U-shaped ring part should be stuck on one side of the rope head, and the pressure plate should be placed on one side of the main rope.
(4) The correct number and method of arrangement: wire rope diameter is less than or equal to 18mm, the minimum number of 3; diameter 18mm ~ 26mm, at least 4;
Diameter 26mm~36mm, at least 5; Diameter 36mm~44mm, at least 6;
Diameter 44mm~60mm, at least 7; After the installation of the chuck, the first and second loads should be checked for looseness. In general, nuts need to be tightened further.
(1) The size of the chuck should be suitable for the thickness of the wire rope. The inner distance of the U-shaped ring is larger than the diameter of the wire rope by 1 to 3 mm. The net distance is too large to be tightly bound to the rope.
