The difference between hand-use strap and machine-use strap
1. Color In general, machine straps are brighter in color than hand straps. Usually, customers can judge by color. The more transparent the color, the purer the raw materials used in the strapping belt, and the better the gloss of the strap. Customers can also distinguish whether it is hand or m...Read more -
Brief Introduction Of Different Types Of Brush Filament (II)
The previous article introduced the common types of nylon brush filament. In this article, other types of artificial brushes are to be introduced that are used in large quantities. PP: The biggest feature of PP is that the density is less than 1, and several of them can be placed in water when te...Read more -
Brief Introduction Of Different Types Of Brush Filament (I)
There are many kinds of brush materials. In early time, people mainly use natural wool. The so-called natural wool are non-synthetic materials that are collected and used directly, such as pig bristles, wool and other. Artificial fiber like PA, PP, PBT, PET, PVC and other plastic filament have th...Read more -
Problems That Organic Fiber Concrete Needs To Solve
