Primary Types of Industrial – Dyes and Pigments

Industrial coloring is quite often used in various industries today; so does the pigment. If we talk about industrial dyes, they are basically coloring, ionizing, and aromatic compounds used in various applications in various industries. Coloring has the character to show affinity for the media. However, they must be used with caution because some industrial dyes are toxic and carcinogenic. However, nowadays, dyes find their application in industries such as plastics, cement, cosmetics, rubber, paper, textiles, medicines, and others. Some of the main varieties of industrial dyes are mentioned below:

Optical Brighteners: Also known as optical agents, optical brighteners are the dyes that possess the attribute of absorbing the violet and ultraviolet region of the electromagnetic spectrum, which results in the prominent re-emission of light in the blue region. This dye is not suitable to be used in water (like in aquarium, etc.), due to its toxic nature.

Digital Textile Printing Dyes: In digital printing, computer controlled ink-jet nozzles or charged drums are used. The physical surfaces over which the digital prints are reproduced include common paper, photographic paper, plastic, cloth, etc. The popular varieties of dyes used for this purpose are acid inks, disperse inks, reactive inks, and dye based inks.

Leather Dyes: Tanneries usually make use of around 50-100 different varieties of leather dyes. Each dye produces a diverse desired effect over the leather. The dyes used in this industry include direct, acid, mordant, reactive, and basic dyes, among others.

Sublimation Dyes: These dyes primarily found their application in various types of printing. They can be found in several forms like inkjet inks, ribbons for thermal transfer, and toner for laser printers. Sublimation dyes are applied by the process called heat-transfer. Their main varieties include acid, disperse, vat, direct, and reactive.

Now, as you might have got some idea about the industrial dyes and their primary varieties, let’s discuss about industrial pigments and their types. Pigments are basically the materials that make a modification in the color of the transmitted light owing to their attribute of selective absorption of the wavelength. The change in the transmission of light varies with fluorescence, phosphorescence, as well as with other forms of luminescence, in which a material emits light. Pigments are generally used in inks, coloring paints, cosmetics, eatables, etc. Nowadays there are various types of pigments available in the market, out of which some primary types of pigments are given under:

Fluorescent Pigments: These pigments have the quality of changing the ultraviolet light into the desired color. They form the vital element of any kind of fluorescent material. The fluorescent pigments are mostly used in textile field, solvent based paper coating, and paints and aerosol coating.

CLC Pigments: Cholesteric Liquid Crystal (CLC) pigments are made from CLC films. These pigments are nowadays increasingly used in security machines and also as an impediment to the counterfeit of currency notes, legal documents, etc.

Ultramarine Pigments: They are a kind of inorganic pigments, which are non-poisonous and non-irritating in nature. They are also one of the oldest varieties of pigments. They have two basic types, viz., ultramarine blue and ultramarine violet. Ultramarine pigments found their application in coating, coloring, printing inks, cosmetics, and artist colors.

Organic Pigments: Organic pigments consist of solid particles and they are insoluble in the application medium. There are two basic varieties of these pigments, namely natural and synthetic. Organic pigments are generally used for coloring or coating purposes (both decorative and protective) on plastics, candles, paper, rubber materials, pharmaceuticals, etc.
 

Electronic Manufacturing Services

You might have a cellphone in your pocket, or somewhere close. Think about how you feel when you accidentally leave it at home. You knocked on your pocket, immediately realized that something was wrong and realization was made – “I forgot my call.” However, imagine a world where the cellphone might not exist. It takes a lot to make a telephone, but without electronic manufacturing services – nothing is possible. Electronic manufacturing services, otherwise known by the acronym EMS are one of the most critical industrial processes in existence when it comes to getting you the products you’ve grown to rely on every day.

When surface mount technology came into existence, it enabled for electronic components to be mounted onto the surface of printed circuit boards, or PCB’s. This eventually made manufacturers capable of rapidly assembling electronics, making them widely available for the general public. For example, when you interact with your computer an electrical charge is sent from one point another using the copper pathways (or traces) laid into the surface of the printed circuit board, providing a completed circuit. When a charge is sent along that circuit, it typically interact with the parts of the circuit board that do the actual work, such as a diode, microchip, or switch.

While printed circuit boards are not the end all be all of electrical connection, they surely make a great deal possible, allowing for smaller devices, miniature components, and much smaller space requirements. Before PCB’s were the standard, a standard electronic device like a television was powered not by a circuit board but by a mess of cables all individually connected to a power supply. So while we might have some of the things we do know, picture a far more antiquated version. Your mobile phone would not fit in your pocket, it would fit in a briefcase and your television would not neatly mount on your wall, it would require a 4 foot deep entertainment center.

You might be wondering where electronic manufacturing services fit into the mix, and the answer is very early. After printed circuit boards are produced, EMS providers are responsible for a wide range of services ranging from basic circuit board assembly and electromechanical assembly to surface installation, flexible circuit assembly, testing, and more. This is a type of operation that adds guts to printed circuit boards, giving them the ability to actually do something more than passing electric charges from one point to another. With EMS, providers can quickly and efficiently integrate and test these devices so that people like us can have ultra portable and high-performance electronics. Or, thought from another perspective, EMS is also used to assemble electronic components for space, military and defense applications – placing missiles reliably in the sky and rockets successfully into orbit. If you think not having a cell phone is bad, think about how a lack of effective electronic manufacturing will have an impact on organizations such as the defense department.
