The raw material for the trimmer line is nylon. Depending on the type of machine and the characteristics of the product, different nylon varieties are required, including nylon 6, nylon 66, nylon 610, nylon 6 & 66 polymer.
The trimmer line first achieves a very high breaking strength and wear resistance. These two are the key criteria for judging the quality of trimmer lines.
At present, the overall quality of domestic trimmer lines cannot reach the technological level of developed countries such as the United States and Japan. This is not only the difference in production processes, but also the difference in the machines themselves. However, in the near future, the level of trimmer lines produced and developed in China will have a qualitative leap.
At present, some domestic factories promote the two-color trimmer line inside and outside, the essence of which is still the same material. There is currently no factory in China, and a research institute can find and use wear-resistant materials to add to the trimmer line. Please pay attention to this situation.
The breaking strength usually needs to reach 180kg or more, otherwise it will cause wire breakage during use and may cause injury to the user.
The wear resistance usually needs to reach 550kgs or more, otherwise the service life of the product will be very short.
If the raw material index used meets the above criteria and the additive formula is properly matched, this standard is not difficult to achieve.
In addition, at present, there are no related trimmer line production and R&D personnel in blindly producing, the raw materials are wrong, the production process is lacking, and the product defects are serious, but the price is lower than the price of the product itself. Caused a lot of market troubles.
At present, the abrasion resistance of trimmer lines produced by similar factories in the United States has reached and exceeded 30,000N, so the wear-resistant materials added to their trimmer lines have been researched and pursued by the same type of factories in China. It is believed that in the near future, such materials will be mastered by the domestic industry. At present, the chemical synthesis wear-resistant materials of the Department of Materials Science in China have made amazing breakthroughs, especially in Tianjin University. I believe that it will be used soon. If such super-abrasive materials are transformed into scientific and technological achievements, there will be a revolutionary breakthrough in the level of trimmer lines in China. And it has a qualitative leap in products in other fields.
