Objects and circuits go electronic: surfaces don’t get stained

Using nanotechnology, a knowledge-based company has helped make 2D and 3D surfaces and objects waterproof in order to boost the performance and durability of products.

Electronic products are sensitive to humidity. The importance of this sensitivity becomes evident when an electronic gear is inadvertently exposed to extreme humidity or come in contact with water. Many pieces of equipment like printed electronic circuits, telephones, headphones, electronic boards and electrical gears need this feature.
Basa Fanavaran Nasir Company’s plasma processing machine that works in a vacuum is a gear capable of making 2D and 3D surfaces and objects waterproof. The machine is used to make waterproof products, particularly in the electronics or textile industries. One important application of the system is that it can create a stainproof feature. It can also activate the surface, make objects resistant to burning, create permanent hydrophilicity, and improve adhesion. The plasma processing machine, otherwise known as Plasma DEJ, can create waterproof and stainproof properties in a broad range of products such as shoes, textile products and electronic systems as well as in the field medicine.
Plasma DEJ industrial water repellent machine is environmentally-friendly because it entails a dry process, that is, it does not use chemicals and water. Further, the machine creates waterproof and stainproof properties in 3D objects in the clothing and textile industry. This adds many other features to various types of shoes, bags, carpets, garments, polyester products and leather.
The features include being waterproof or hydrophobic. These two properties help protect the body’s health for people wearing the shoes and clothes. Meanwhile, besides textile products, electronic devices such as tablets or mobile phones can also be put in the machine to develop hydrophobicity.
The device produces polymer layers on the products placed therein, such as shoes or clothes. The polymer layers are one nanometer thick or as thin as several layers of molecules. These layers give the products waterproof and stainproof properties but do not affect their appearance or mechanical properties.
The polymer layers do not work the way a nylon mesh fabric does by covering pores and affecting breathability in products such as shoes or clothing. Actually, the layers are wrapped around each piece of yarn. Surface tension in these polymer layers is very low, which causes water droplets to slip off the surface, thus preventing water absorption in the product.
There are no equivalents of the product in the Iranian market, and its most important feature, compared to products of foreign companies, is the cost price thereof, which is one fifth of the foreign peers.
