Simple and Efficient Rout for Synthesis of Ceramic Pigment

Ceramic pigments are the general name of the pigments used on ceramics, including glaze stain, underglaze stain and body stain. In the process of production, these pigments need to be calcined at different temperatures. The requirements for temperature are different according to different use of pigments.

In previous reports, pure and crystalline Mg1-xCoxAl2O4 powders were obtained only after annealing the as-prepared amorphous powders at high temperatures.

Few reports on this topic show that the preparation of same ceramic pigments involves annealing at 1400°C for 3h. Even applying new methods such as sonochemical synthesis requires heating treatment at 1000°C at least for 2 hours for the formation of pure cobalt aluminate spinel phase.

Generally, increasing temperature treatment increases the crystallite sizes of powders. So preparation of single phase spinel nanoparticles at lower temperatures is the advantage of our liquid combustion method and makes it technically simple and cost effective.

Cloverdale Paints Industrial Enamel

Industrial enamel is the most commonly used material to protect steel. Industrial enamel systems for steel structures have developed over the years to comply with industrial environmental legislation and in response to demands from bridge and building owners for improved durability performance.

Previous five and six coat systems have been replaced by typically three coat alternatives, and the latest formulations have focussed on application in even fewer numbers of coats, but with increasing individual film thickness. Examples of this are epoxy and polyester glass flake coatings that are designed for high build thickness in one or two coat applications, and single coat high build elastomeric urethane coatings, up to 1000μm thick.

Modern specifications usually comprise a sequential coating application of Industrial enamel or alternatively paints applied over metal coatings to form a ‘duplex’ coating system. The protective Industrial enamel systems usually consist of primer, undercoat(s) and finish coats. Each coating ‘layer’ in any protective system has a specific function, and the different types are applied in a particular sequence of primer followed by intermediate / build coats in the shop, and finally the finish or top coat either in the shop or on site.

All the information on cadmium yellow

Cadmium yellow pigments are stable, inorganic colouring agents which are produced in a range of rich, vibrant shades of yellow, orange, red, and maroon. Modern day pigments are carefully engineered products manufactured in regulated chemical plants with full Health and Safety and Environmental permits under Responsible Care management and adherence. These cadmium yellow pigments have a carefully defined and engineered particle size, crystal structure, surface area and surface treatment to ensure they are not only correct for colour but also meet extremely low solubility and other key property limits.

The pigment chemistry is based on solid solutions of Cd,Zn, S, Se formed by calcining at high temperature to convert fully to a crystalline and stable hexagonal form, before undergoing a series of further treatments resulting in highly engineered pigment grade products.

These properties make cadmium yellow pigments unique. Being difficult to substitute, they are typically the materials of choice for ceramic, glass and metal decoration, plastic colouration and for the professional artist including restoration work.

Applications

Cadmium yellow pigments find niche applications in market segments where their unique blend of properties of clean colour shade, intensity, opacity, heat and light resistance and long-term stability are paramount.

Plastics

Cadmium yellow pigments have inherent high temperature resistance because of their method of manufacture and may therefore be used routinely in polymers which are processed at or above 300ºC e.g. polycarbonate, nylons and PTFE. Further, because of this high temperature resistance, all moulding sprues and off-cuts can be recycled whereas an organic may already be starting to undergo decomposition during moulding and be unable to withstand further heating.

How to clean porcelain enamel

It is best to clean porcelain enamel cookware right away as the surface can crack and chip if food residues are left to dry inside the pot or pan.

Avoid using steel wool scrubbers or other abrasive cleaning items on porcelain enamel. Some porcelain enamel cookware is dishwasher safe, just be sure to check first and to wipe out food residues before putting porcelain enamel in the dishwasher.

As porcelain enamel is part metal, it is typically not microwave safe. It may be useable on induction cooktops, though, so is a great option if you’re looking for cookware options in an energy efficient kitchen.

All in all, I’d say porcelain enamel is a decent option for eco-friendly cookware, but you’re much better off with ceramic, cast iron, carbon steel, stainless steel, or metal-ceramic, rather than porcelain enamel.

Benefits of industrial enamel

Industrial enamel is porcelain enamel (also called vitreous enamel), which is dry milled & coated with an organic layer in order to make it suitable for electrostatic charging.

Industrial enamel refers to a modern industrial enamel technology, which involves the spraying & deposition of electrostatic charged dry powder enamel on metal substrates.

This relative new application method has many benefits compared to traditional wet enameling and is therefore preferred by major appliances & water heater manufacturers worldwide.

Benefits of industrial enamel

Industrial enamel has many benefits compared to traditional wet enameling, such as:

  • Improved coating quality
  • Simplification of enameling process
  • Reduction of enameling cost
  • Environmental friendly
  • Saving factory floor space

Understanding the different types of porcelain enamel coating

Manufacturers use polyurethane porcelain enamel coatings in a wide array of environments, often as a protective final coat over other custom formulated industrial primers. Polyurethanes resist abrasion, and can enhance durability to withstand wear and tear and abuse.

These porcelain enamel coatings maintain color and can have an attractive, high-gloss finish, if desired. Aliphatic polyurethane porcelain enamel coatings have good UV and environmental durability. Such porcelain enamel coatings are a good choice for outdoor applications.

Aromatic polyurethane products resist degradation in wet conditions or underwater, but they tend toward fading when exposed to UV light. These porcelain enamel coatings can work well in interior environments.

Two component polyurethanes do require protection for workers when applied, as with many other types of chemical processes. They are available in low VOC formulations.

How long does enamel powder coating last?

Enamel powder coating can maintain its finish up to 15-20 years, depending on pre-treatment and the type of powder. Its resistance to weather, corrosion, and chemicals makes enamel powder coating a more durable finish than paint or other liquid coatings.

Enamel powder coating pre-treatment

Pre-treating your substrate is the most important process to getting maximum life out of your enamel powder coating. Because the powder particles are electrostatically charged onto the surface, it’s imperative for that surface to be clean for proper adherence. Most pre-treatment includes stripping any existing coating and corrosion, and cleaning the bare metal.

If your substrate is pre-treated poorly or not at all, your enamel powder coating will chip easily and have a very short life.

Here, our new automated six-stage pre-treatment system is the best solution available for a thorough and consistent cleaning. Even laser scale can be removed. Manual washes are also available, if your project requires it. We use only environmentally safe chemicals for all pre-treatment solutions.

Longevity of enamel powder coating types

There are various types of powders available for a range of applications.

Epoxy – Extremely durable and excellent resistance to corrosion and chemicals. Best used indoors, as sun and weather can cause fading and deterioration within a matter of months. We recommend the use of epoxy primers as the first step in our 2 coat process. When coupled with a UV stable top coat this combination will ensure your coating project lasts for years down the road.

Polyester – One of the most commonly used powders, polyesters have a large selection of colors and gloss. Great for interior and exterior applications. Super durable chemistries offer good resistance to chemicals, corrosion, and UV weathering.

Fluoropolymers – Incredible weathering capabilities allow fluoropolymer powders to retain gloss and colors very well. They are also resistant to corrosion. An excellent choice for outdoor applications. Warranties up to 20 years can be available when applied to specific surfaces by a certified applicator.

Porcelain Enamel Coatings

Porcelain enamel coatings have their origins in ancient times when they were mainly used for decorative and ornamental purposes. From the industrial revolution onwards, these coatings have started to be used also as functional layers, ranging from home applications up to the use in high-technological fields, such as in chemical reactors.

The excellent properties of porcelain enamel coatings, such as fire resistance, protection of the substrate from corrosion, resistance to atmospheric and chemical degradation, mainly depend and originate from the glassy nature of the porcelain enamel matrix itself. On the other side, the vitreous nature of porcelain enamel coatings limits their application in many fields, where mechanical stress and heavy abrasion phenomena could lead to nucleation and propagation of cracks inside the material, thus negatively affecting the protective properties of this coating. Many efforts have been made to improve the abrasion resistance of enamelled materials.

On this regard, researchers showed encouraging results and proposed many different improvement approaches. Now it is possible to obtain porcelain enamels with enhanced resistance to abrasion. Differently, the investigation of the mechanical properties of porcelain enamel coatings remains a poorly studied topic. In the literature, there are interesting methodological ideas, which could be successfully applied to the mechanical study of enamelled materials and could allow to have further insights on their behaviour. Thus, the path that should be followed in the future includes the mechanical characterization of these coatings and the search for new solutions to address their brittle behaviour.
