Surface technology for the chemical industry

Invulnerable surfaces for clean processes

The chemical industry requires surfaces which are both easy to clean and very resistant to chemicals and high temperatures. With surface optimisations by Aalberts surface treatment, even the most challenging production environments will not hold any unpleasant surprises. We have been active in the sector for nearly 60 years now. With our chemical surface treatment technology, we bring increased efficiency and higher quality to chemical companies.

Challenges in the chemical industry

Chemical processes are particularly sensitive to any type of contamination and/or foreign bodies that enter the production plants while the process is running. Another particular challenge is the application of protective coatings to components and plants which come into contact with aggressive media. Coatings in the area of chemical processes need to be 100% free from pores and resistant to a wide variety of chemicals. Easier cleaning, high temperature resistance and good non-stick properties are equally important.

The many challenges of surface technology in the chemicals industry at a glance:

  • Wear and tear
  • Corrosion
  • Static charge
  • Contamination
  • Aggressive chemicals
  • High temperatures

In order to be able to master these challenges, the surface must be very resistant and of high quality. Moreover, these properties have a positive effect on the production results and the economic efficiency.

More than 850 customers from all over the world are relying on our high-performance surface finishes. As experts in the field of innovative high-quality surfaces, we at Aalberts surface treatment demonstrate every day that surface technology in the chemicals industry is one of our core competencies, no matter how the challenges may look like in your company.

Polymer coatings -
highly customisable protection

Special fluoropolymer and polymer coatings have become very well established as surface coatings in the chemical industry. These hydrophobic plastic coatings are characterised by outstanding non-stick and traction properties, longevity and superior corrosion protection. Featuring thicknesses from a few to several hundred µm, the layers offer long-term protection against aggressive bases and acids with a pH value of up to 12. They have no trouble whatsoever in resisting temperatures of more than 250°C. What is more, they become firmly anchored in the substrate and are suitable for a wide variety of (non-)ferrous materials:

  • Steel
  • Stainless steel
  • Aluminium
  • Plastics
  • Ceramics
  • Copper

Our expert personnel will tailor the surface structure and roughness (from approx. 1.5 µm) to your individual needs. Problems arising in connection with the processing of substances which are extremely difficult to remove can thus be reduced: you will be able to clean containers in less time and without leaving any residues, while the consumption of release and cleaning agents decreases along with the need for maintenance.

Customised chemical surface treatment technology

Aalberts surface treatment offers products which are already perfectly suited for a wide variety of applications. With nineteen partially patented special surface finishes, our surface technology is represented in many branches of the chemical industry. Not only do our development engineers focus on the expansion of the current processes, but they continuously work on the implementation of innovative ideas.

Hereinafter you will find three case studies on the benefits of our chemical surface treatment technology.

To the processes
  • Biodiesel is an aggressive fuel which causes damages to the tanks in which it is stored. The replacement or repair of biodiesel tanks is time-consuming and expensive, which is why the inner tank walls must be resistant to chemicals and corrosion. Thick-layered polymer and fluoropolymer coatings (MagnaCoat®) protect the surfaces against corrosion and the damaging effects of biodiesel. It is possible to save on paintwork, repairs and premature new acquisitions.

  • The manufacture of paints and varnishes involves the use of mixing containers and agitators. The blending process occurs at high speeds. Solvent vapours can escape. Due to the static charge of the agitator, there is a risk of reaction with these solvent vapours. What is more, the containers and agitators need to be cleaned, in a time-consuming manner, before each new blending process.

    By applying a ChemCoat® version specifically developed for this type of application, it is possible to keep paint residues from sticking to mixing containers and agitators. ChemCoat® is a series consisting of high-quality non-stick and anti-friction coatings. We use carbon fibers to ensure that the coating is conductive. Thus, it is possible to reduce cleaning times and avoid static charges.

  • The mining of brown coal also involves transporting wet coal for the purposes of further processing. This task is taken care of by conveyor systems. These conveyor systems also contain vertically arranged conveyor plates, which due to the wet coal's weight, are subject to heavy wear. Apart from this, these plates often are clogged by the sticky mass so that repeated cleaning is required.

    When coating these conveyor plates with PlasmaCoat®, companies active in this field can benefit from good wear protection and ideal non-stick properties. Transport problems caused by wet Lignite become outdated, while the plates' replacement intervals become longer. What is more, PlasmaCoat® will significantly reduce your cleaning and maintenance costs. This coating process merges the extreme surface hardness and extraordinary wear protection of thermally sprayed metal or ceramic coatings with the non-stick and anti-friction properties of polymers and fluoropolymers.

Our strength is your advantage
