Electronic circuit coating is a method applied to the printed circuit board (PCB) to protect circuit boards and circuit elements against environmental conditions (humidity, dust, vibration, etc.) and to prevent corrosion. So what is a PCB? PCB or Printed Circuit Board (printed circuit board) is called the plates on which the electronic circuit elements are placed and the electrical connection between these elements is provided by means of copper surfaces. Briefly, PCBs have two important purposes; – Keeping electronic components together – To provide electrical connection between components. Protective coatings are designed to protect solder joints, leads of electronic circuit components, exposed traces and other metallized areas from corrosion, the conformal protective coating process extends the working life of the PCB.
Electrically conductive adhesives are primarily used for electronic applications where the circuit elements are held in place and the electric current formed between them can be transmitted. Conductive adhesives gain conductive properties thanks to the mixture of metals such as silver, gold, copper, nickel, graphite and chemical resins. Unlike electrically conductive adhesives, most common adhesives (anaerobic adhesives, cyanoacrylate adhesives, epoxy adhesives, and acrylic-based adhesives) act as an electrical insulator.
Repair putty is an epoxy-based sealant with a polymer structure. Repair pastes are products that can be processed, drilled and painted mechanically and have steel, aluminum and plastic filling properties. They are materials that fill cracks, collapses, cracks or gaps in various equipment and obtain a similar and equal surface to the applied surface. Metal, aluminum, plastic, wood etc. It can be used easily on all surfaces and materials. It is resistant to oils, hydrocarbons, alcohol, hot and cold water, acids and bases. It is resistant to vibrations and helps prevent corrosion.
Friction between the contact surfaces of the two machine elements that are in contact and in motion, and accordingly, the temperature rise and wear and energy loss between the elements occur. In today’s industry, energy losses are seen in every machine in every field. The expectation of 100% yield has always been impossible. In some studies conducted by various organizations in the world, it has been revealed that one third of the energy produced is spent at the end of friction. In addition, it has been determined as a result of similar studies that the abrasions on the machine functional surfaces cause enormous economic losses. In order to minimize the energy loss experienced, lubricants are used to reduce or completely eliminate the contact surfaces, and this is critical.
UV light is part of the electromagnetic spectrum. Ultraviolet rays are electromagnetic radiations that fall between visible light and X rays. Ultraviolet or ultraviolet (abbreviated UV) radiation is called radiation with a wavelength between 100 and 400 nm. Due to their short wavelengths, they cannot be seen with the human eye. Our eyes are sensitive to wavelengths between 400 and 700 nm.
Sealing gaskets are the elements that play the role of combining between different installation and machine parts in order to prevent leakage in general. The gasket provides the sealing with the compression process. Sealing is possible with the harmonious operation of all components in the system.
Epoxy adhesive is a thermoset polymer plastic material with an extremely strong, durable and flexible structure that can withstand environmental conditions. Epoxy adhesives basically consist of epoxy resin and hardener. During the application, the components enter into a chemical reaction and form the desired structure. In this way, epoxy adhesives provide versatile application opportunities in different areas. In addition, it allows high tensile and impact strength material connections and is ideal for maintenance-repair-process processes.
In addition to traditional fastening methods such as bolts, rivets and welding, bonding is also an accepted joining technique. Metal adhesive is a natural or synthetic substance used to join or bond two or more metal surfaces with a bond that is strong and flexible enough to resist separation without the need for conventional methods such as nails and screws.
In order to achieve the best results, it is necessary to use the metal adhesive that is most compatible with the material to be fixed. So there are some additional factors to consider before deciding on the use of adhesive. For example, the adhesive must be suitable for the materials to be bonded, match the manufacturing method, withstand the calculated working loads and the working environment. In addition, surface preparation, application method, curing system and their time and costs should also be considered.
Metals are materials that are frequently encountered in many tools and equipment that we use in our daily lives. Many materials, from the cutlery we use while eating to the pipes and valves in our homes, the toys we play with, or the bicycles and cars we ride, are either completely made of metal or contain metal. With the intensive use of these materials in our lives, it is possible to encounter terms such as rust and rusting. Rust is a hydrolyzed iron oxide (Fe2O3) compound that occurs as a result of the chemical reaction caused by the presence of metal and metal alloys in humid, humid or acidic environments. At the same time, corrosion is used as a higher heading and you can click the link to read our article on the subject.
Corrosion is the event that they lose metallic properties by entering chemical or electrochemical reactions with the medium they are in metals. The most general sense is that materials are not able to be corrupted by environmental impact. All kinds of material made from metal undergo less or very corrosion during use.
