4. Confirm the Crafts of the colored Coating: Only Ultrasonic Titanium Coating
We know reusable steel straws are used for drinking and safety is very important. When it comes to colored, metal straw wholesaler or distributor or customer will consider is the colored metal straws safe to our health? Actually, there are 3 kinds of colorful coating for the extra long metal straws. And also it’s necessary for you to know the difference between Ultrasonic Titanium Coating, Water Electroplating, and Water Electroplating.
1 Ultrasonic Titanium Coating: FDA passed
It featured a long-lasting Stable membrane performance and high safety (FDA-approved, implantable)
Here below is the advantage of Ultrasonic Titanium Coating:
- The film layer has a strong bonding with the surface of the workpiece, which is more durable and wears resistant.
- The diffraction performance of ions is good, and it is possible to plate workpieces with complex shapes.
- The high deposition rate and high production efficiency
- The wide range of coatable layers
- Stable membrane performance and high safety (FDA-approved, implantable)
2 Water Electroplating: color shiny but not safe. Not Eco.
Water Electroplating is related to water and an aqueous solution as the name implies, and the principle of electrochemical reaction is a chemical process. Due to the large use of water/water solution, the pollution is large.
Considering drinking function, we can’t use Water Electroplating to coat or plate on stainless steel straw.
3 electrostatic spraying: Low Pirce Harmful to your health.
Hazard: Spraying paint without protection, the concentration of benzene in the air of the workplace is quite high, which is extremely harmful to paint sprayers. Long-term exposure to benzene can cause chronic poisoning, resulting in leukopenia, thrombocytopenia, bone marrow hematopoietic dysfunction and other diseases. The harm to the human body can not only occur through the inhalation of the lungs but also through the skin. The human skin is directly in contact with the paint, which can dissolve the fat in the skin, causing the skin to crack, inflamed and enter the human body.
Some Jieyang metal straw factory use electrostatic spraying to the coating on the straw and it’s looking great, But it’s very very bad to your health and it’s No business ethics to sell the stainless steel straws bulk.
You need to remember that any Red metal straw is using electrostatic spraying to coat, and you should pass the factory immediately.
