Nitinol tube surface modification

Nitinol tube surface modification -- Medical instruments -- YMUS ultrasonic spraying

Nickel-titanium alloy, also known as memory alloy, is a kind of special alloy material with memory effect. It is mainly composed of two elements, nickel and titanium, and the usual chemical composition is NiTi (the ratio of nickel to titanium can vary).

Based on these characteristics, Nitinol alloy has been widely used in many fields, mainly used in minimally invasive surgery, product categories are: medical Nitinol alloy can be used to manufacture heart occluders, aortic coated stents, wire guide products, kidney micro-pumps, vascular stents, esophageal stents, bone fixators, surgical sutures, dental orthodontic wire and other implantable medical devices; Medical Nitinol has a wide range of clinical applications, including general surgery, minimally invasive surgery, medical cosmetology, dental orthodontics and so on.

YMUS ultrasonic spraying technology uniformly prepared TPU solution on the surface of NiTi tube.

1. Uniformity: Ultrasonic spraying technology can produce high-frequency acoustic vibration, the liquid particles evenly sprayed on the nickel-titanium tube, you can get a uniform, dense coating, to avoid the coating of non-uniformity and defects.

2. Strong adhesion of the coating: ultrasonic vibration can promote the adhesion between the coating and the substrate, improve the adhesion of the coating. In the process of TPU solution spraying, the vibration effect of sound wave can better bind the coating to the surface of nickel-titanium tube, and enhance the adhesion of the coating.

3. Solvent saving: compared with traditional spraying methods, ultrasonic spraying technology can better use and penetrate the solution, thereby reducing the amount of solvent used. This not only benefits environmental protection, but also reduces preparation costs.

4.  Particle size control: ultrasonic vibration shear and disperse the particles in the solution, which can control the size and distribution of the particles in the solution. This helps to obtain the desired coating quality and performance.

5. High efficiency and fast: ultrasonic spraying technology is simple, fast and efficient, and the coating preparation time is short. The continuity and adjustability of the spraying equipment enable the TPU solution to be uniformly sprayed on the nickel-titanium tube in a short time.
