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
(1) Develop and develop fibers with better performance, strengthen the adhesion between the fiber and the matrix, improve the elastic modulus and anti-aging performance of the fiber, improve the dispersion of the fiber in the matrix, and prevent the deterioration of the performance of the fiber i...Read more -
Research & Application Status Of Organic Synthetic Fiber Concrete (II)
2.2 Nylon fiber concrete Nylon fiber concrete is one of the earliest polymer fibers used in cement and concrete, the price is relatively high, and the application is limited. The incorporation of nylon fiber can significantly reduce the dry shrinkage value of concrete, but the flexural, compressi...Read more -

2.1Polypropylene fiber concrete From the research situation in recent years, it can be seen that polypropylene fiber reinforced concrete is the most widely studied fiber reinforced concrete material. Research at home and abroad focuses on the physical and mechanical properties of fiber concrete,...Read more -
The Role Of Organic Fibers In Concrete (II)
1.3 Improvement of impact resistance to concrete Impact resistance refers to the ability to resist the damage caused by the impact of an object when it is impacted. After organic fibers are incorporated into concrete, the compressive strength and flexural strength of concrete are increased to var...Read more -
The Role Of Organic Fibers In Concrete
Due to its high compressive strength and low cost, concrete is the most used building material in the construction field. However, due to its large brittleness, easy cracking, low impact resistance and other shortcomings, it restricts its further development. The use of organic synthetic fibers t...Read more -
Commonly Used Organic Synthetic Fibers & Their Performance Indicators
Concrete is a brittle material with high compressive strength and relatively low tensile strength. With the continuous development of modern construction technology, higher requirements have been put forward for cement concrete, the largest building material. Therefore, ...Read more -
Interpretation And Application Of Polypropylene T30S
30s is a specification of polypropylene, mainly used in the production of membrane crack fiber (agricultural rope, string, spinning, etc.) monofilament, stretch film, tube film, etc. T30s is the lightest of the general-purpose resins, with good rigidity, light transmission, corrosion resistance, ...Read more
