A Catalyst to Longevity of your Product–Industrial Coating

Coating is a covering applied to a product usually referred to as the ‘substrate’ with a layer of liquid or powder. It is done either for decorative or protective purpose or even both. Coating may be all-covering or may also cover some parts of the substrate.
There has been an increasing demand for industrial coating in the market. Industrial coatings are essentially specialized paints that are used for protective and functional purposes, to resist corrosion and destruction from dust and other materials thus increasing the longevity of the product and enhancing its functions. Coating helps the substrate to achieve a desired level of strength, surface tension and a perfect finish.
Coating is used on the following materials or products:

  • Pharmaceutical Tablets: are coated to confer specific benefits; that broadly range from facilitating product identification to modifying drug release from the dosage form.
  • Food Items: are coated for various purpose namely; adding nutritional value, enhancing taste and longer preservation.
  • Metal Equipments: are coated for durability, to reduce wear & tear and protection against corrosion.
  • Wooden Furniture: are coated for it provides durability, rich colour and minimizes hazards.
  • Glass: is coated for protection from mechanical and chemical stress, increased scratch resistance and shatter protection and also for beautification.
  • Textile/Fabric: is coated for superior heat protection, exceptional durability and resistance to chemicals and abrasion.
  • Paper: is coated to give water resistance and wet strength to the paper or to protect against ultraviolet radiation.
  • Plastic: is coated for resistance from heat and for rough & tough features to last long.

Types of Coating:

  1. Powder Coating – Powder coating is a multi-step finishing process.
    i: The product is cleaned and prepared for coating.
    ii: It is coated with a fine powder. The powder covers the product’s surface.
    iii: The product is then moved into a curing oven, to get heated, allowing the powder to melt and flow into a uniform coating that adheres to the product, creating a very durable and attractive coating around the product after the melted powder cools and hardens.
  2. Liquid Coating – Liquid paint coating is the simple application of paint to products, with the help of various machineries.

Paper Coating Machine

The paper and paper products plays more substantial role in the day-to-day life of the human, its usage are increasing every day in as newspapers, magazines, envelopes, books & diaries, stationeries, packaging and etc. the usage of paper and paper related products have become nearly unlimited. The increasing application has increased the demand of quality paper, majorly the paper quality is defined in terms of its smoothness, glossy finish, printability, uniform thickness and moisture contain.
The increasing demand of the paper the manufacturers wanted to have the paper manufacturing machines to produce higher quality paper, increase productivity, reduction in the waste, safe and improved process control. The paper manufacturing and paper coating process is known as one of the major dewatering process, which requires removal of all even a small amount of water also by the way of evaporation for the quality paper and coatings. The paper machine consist of the four sections Forming Section, Press Section, Drying Section, Calender Section. Wikipedia explains the sections as follows:

  • Forming section, commonly called the wet end, is where the slurry of fibres filters out fluid a continuous fabric loop to form a wet web of fibre.
  • Press section where the wet fibre web passes between large rolls loaded under high pressure to squeeze out as much water as possible.
  • Drying section, where the pressed sheet passes partly around, in a serpentine manner, a series of steam heated drying cylinders. Drying removes the water content down to a level of about 6%, where it will remain at typical indoor atmospheric conditions.
  • Calender section where the dried paper is smoothened under high loading and pressure. Only one nip (where the sheet is pressed between two rolls) is necessary in order to hold the sheet, which shrinks through the drying section and is held in tension between the press section (or breaker stack if used) and the calender. Extra nips give more smoothing but at some expense to paper strength.

The most critical part of the paper making process is drying the paper post press section to leave around 6% of the moisture contain within paper, hence the selection of the dryer and drying technology plays very vital role in total paper production system. In the dryer section, the paper entanglement passes over rotating; a cast iron cylinder which was heated by the means of heat transfer mechanism such as Convention, Conduction and/or Radiation and the most of the remaining water is removed by evaporation. When the paper leaves the dryer section its solid content has increased to about 90-95%. Thermal energy transferred from the heater is used for the dewatering of the paper in the dryer section.
Since the drying is critical in the entire paper production process as overlooking its criticality by the paper manufactures and/or plant operators may results in improper paper quality of paper, increased waste and reduced production. Hence the choice of the drying technology and dryers needs to be done properly by consulting with the leaders in the field of heater and heating technologies such as KERONE.
