Introduction
With the rapid development of the fitness industry, the quality and durability of fitness equipment have become the focus of consumers and manufacturers. The surface treatment technology of fitness equipment directly affects its service life and user experience. Bis-(2-dimethylaminoethyl) ether (hereinafter referred to as “bis-ether”) is a new surface treatment material. Due to its excellent wear resistance and chemical stability, bis-(2-dimethylaminoethyl) ether (hereinafter referred to as “bis-ether”) has gradually been used in the surface treatment of fitness equipment. This article will discuss in detail the wear resistance of bis ethers in the surface treatment of fitness equipment, including its product parameters, application effects, testing methods and future development directions.

1.3 Chemical Properties
Diesethers have good chemical stability and can remain stable over a wide pH range. It is not easy to react with common acids and alkalis, but may decompose under the action of strong oxidants. The molecular structure of the bisether contains ether bonds and amino groups, which make them exhibit excellent adhesion and wear resistance during surface treatment.
2. Application of bis ether in surface treatment of fitness equipment
2.1 Surface treatment process
The application of bis ether in surface treatment of fitness equipment mainly includes the following steps:
- Surface Cleaning: Use organic solvents or alkaline cleaning agents to remove oil and impurities on the surface of the equipment.
- Primary Coating: Apply a primer to the cleaned surface to enhance the adhesion of the bisether coating.
- Di-ether coating: The bi-ether solution is evenly applied to the surface of the equipment, usually using spray coating or dip coating.
- Currecting treatment: Carry out the curing treatment at an appropriate temperature to form a dense protective film for the bis ether coating.
- Surface Polishing: The cured coating is polished to improve surface finish and wear resistance.
2.2 Application Effect
Di-ether coatings show the following advantages in surface treatment of fitness equipment:
- Abrasion Resistance: The bis-ether coating has excellent wear resistance and can effectively resist friction and scratches in daily use.
- Corrosion resistance: Bi-ether coating can resist the corrosion of chemical substances such as sweat and detergents, and extend the service life of the equipment.
- Adhesion: The bis-ether coating has good adhesion to the surface of the equipment and is not easy to peel off.
- Aestheticity: Bi-ether coating can provide a smooth and uniform surface and enhance the appearance texture of the equipment.
2.3 Application Cases
The following are some examples of fitness equipment treated with biether coating:
| Equipment Type | Processing Effect | User Feedback |
|---|---|---|
| treadmill | Smooth surface and strong wear resistance | No obvious wear and tear for one year |
| Dumbbell | Even coating, comfortable feel | Good grip, not easy to slip |
| Exercise Bike | Corrosion-resistant, easy to clean | Easy to clean, long-lasting appearance |
| Strength training equipment | Strong adhesion, not easy to peel | The coating is intact after two years of use |
3. Wear resistance test of bis-ether coating
3.1 Test Method
To evaluate the wear resistance of bis-ether coatings, the following test methods are usually used:
- Taber wear test: Use a Taber wear instrument to perform wear test on the coating to record weight loss before and after wear.
- Scratch Test: Use a scratch tester to perform scratch testing on the coating to evaluate the scratch resistance of the coating.
- Friction Test: Use a friction tester to perform friction test on the coating to record the friction coefficient and wear.
- Practical use test: Long-term observation of the coating in the actual use environment to record the wear.
3.2 Test results
The following are the wear resistance test results of some bis-ether coatings:
| Test Method | Test conditions | Test results |
|---|---|---|
| Taber wear test | 500 rpm, CS-10 grinding wheel | Weight loss 0.5mg |
| Scratch Test | 1N load, diamond stroking | Scratch width 10μm |
| Friction Test | 100N load, 1000 frictions | Friction coefficient 0.15 |
| Practical use test | Treadmill, use for one year | No obvious wear |
3.3 Results Analysis
From the test results, it can be seen that the bis-ether coating exhibits a low weight loss in the Taber wear test, indicating that it has excellent wear resistance. Scratch test results show that the bis-ether coating can effectively resist scratches and maintain surface integrity. Friction test results show that the bis-ether coating has a lower coefficient of friction and can reduce wear caused by friction. The actual use test further verified the wear resistance of the bis-ether coating, and there was no obvious wear after one year of use.
IV. Optimization and improvement of bis-ether coating
4.1 Formula Optimization
To improve the wear resistance of the bis-ether coating, it can be achieved by optimizing the formulation. For example, add nanofillers (such as nanosilicon dioxide, nanooxidationAluminum) can enhance the hardness and wear resistance of the coating. In addition, adjusting the ratio of bis ether to curing agent can improve the cross-linking density of the coating and improve wear resistance.
4.2 Process improvement
In terms of coating processes, a multi-layer coating technique can be used, i.e., an intermediate layer between the primer and the topcoat, to improve the overall performance of the coating. In addition, optimizing curing conditions (such as temperature, time) can promote sufficient curing of the coating and improve wear resistance.
4.3 Surface treatment technology
Using advanced surface treatment technologies, such as plasma treatment and laser treatment, can improve the roughness and chemical activity of the surface of the equipment, enhance the adhesion of the bis-ether coating, and thus improve wear resistance.
V. Future development direction of bis-ether coating
5.1 Environmentally friendly biether coating
With the increase in environmental awareness, the development of environmentally friendly biether coatings has become a future development trend. By using aqueous bis-ether solutions or bio-based raw materials, environmental pollution can be reduced and the requirements of green manufacturing can be met.
5.2 Multifunctional biether coating
The future biether coatings need not only excellent wear resistance, but also other functions, such as antibacterial, anti-static, self-cleaning, etc. By adding functional fillers or modifiers, the versatility of the bis-ether coating can be achieved.
5.3 Intelligent biether coating
With the development of intelligent technology, intelligent biether coating has become possible. For example, by embedding sensors in the coating, the use status and wear of the equipment can be monitored in real time, providing users with intelligent maintenance suggestions.
VI. Conclusion
Bis-(2-dimethylaminoethyl)ether, as a novel surface treatment material, exhibits excellent wear resistance in surface treatment of fitness equipment. The performance of the bis-ether coating can be further improved by optimizing the formulation, improving the process and adopting advanced surface treatment techniques. In the future, environmentally friendly, multi-functional and intelligent biether coatings will become the main direction of development, providing more possibilities for the surface treatment of fitness equipment.
