Do you know the origin of anti loosening nylon powder for screws

Rohm Haas and Nylok collaborated to develop this special material, which is mainly divided into nylon 11 resin, a long carbon chain flexible nylon refined and processed from castor oil. When the shear force exceeds the yield strength of nylon 11. To tighten or loosen screws, the destructive force generated by ordinary vibration cannot reach the yield strength of nylon 11. So far, no other material has been found to be more suitable for screws than nylon 11. Through cooperation with material manufacturer Rohm Haas, nylok has become a leading brand in the global screw anti loosening industry.

In the past, to prevent screws from loosening, we used liquid glue to seal the ends of the screws. There were methods such as drilling holes and embedding nylon strips to prevent loosening, and adding spring washers to prevent loosening. However, the anti loosening effect was often not obvious or the efficiency was low, making operation inconvenient. In the past decade, screw anti loosening nylon powder technology has been introduced to China, rapidly developing and growing. More and more users have recognized the anti loosening reliability, reusability, and convenience suitable for assembly line operations of this product. It has been successfully popularized in the mobile phone industry, sports equipment, high-end furniture, automotive parts, and other fields.

The small invention and creativity of American company Nylok have brought a revolution in the field of screw anti loosening. They have found a special material to easily achieve the anti loosening effect of screws, which can be repeatedly used and has a significant anti loosening effect. It can be produced on a large-scale assembly line.

The material must meet the following requirements: 1. It is a heat shrinkable material with elasticity. 2. Strong adhesion with screws: not easy to loosen, resistant to oil and solvents. 3. Moderate hardness: The hardness is too high, making it difficult to lock the screws, the hardness is too small, and the torque cannot be guaranteed.

Before using this product, remove oil and rust from the screws. Oil stains on the substrate will significantly affect the adhesion of the coating. It is not recommended to heat the screws too high. When the temperature is above 330 ℃, the degradation rate of nylon 11 will accelerate, which will also affect the interlayer adhesion. It is recommended to set the temperature so that the surface can form a sand like shape. If the temperature is too high, the surface will flow flat, and the resistance to torque will be reduced. When this product is not in use, it needs to be wrapped to prevent moisture.

Our company is the agent of Rohm Haas company's nylon powder in China. The colors include blue, red, orange, coffee, gray, green, etc. Depending on the size of the screw teeth, different product models are corresponding. In addition, for some special screw models, there are special models that do not require secondary electroplating for surface coating differences.
