What is color coating line?
This is a pre-coating line that forms coats through advance application and baking of coating materials onto strips produced by Continuous Galvanizing Lines (CGL; to enhance corrosion resistance) and Continuous Annealing Lines (CAL; to improve properties, such as strength and elongation).
What is a coating line?
Coating line means an operation which is a single series in a coating process and which is comprised of 1 or more coating applicators and any associated flash-off areas, drying areas, and ovens wherein 1 or more surface coatings are applied and subsequently dried or cured.
What is a coating line operator?
Coating Machine Operator Operation of coater for application of various coatings. High degree of on-line inspection for optical defects. Mechanical ability to change coating cylinders and rollers, with extreme care,…
What is coil coating process?
Coil coating is the method by which a metal coil is coated in a continuous process prior to fabrication. The metal coil is brought through an uncoiler, a line-loading accumulator, processed and painted according to requirements, brought through a finish line exit accumulator and then rewound on a recoiler.
What is Colour coated steel?
Also known as pre-painted steel, the manufacturing process of colour coated steel involves applying a decorative coating (liquid paint) to a coiled steel form. This paint coating protects the steel from atmospheric corrosion while giving it more strength and enhancing the durability.
How are coil coatings applied?
Coil coating is how the coating material is applied to the strip of steel or aluminum. A coil of metal sheet is continuously fed into the process which is controlled via accumulators at each end of the line. They take in a bare coil of metal at one end and let out the finished product on the other end.
What is coil and extrusion coatings?
Coil coatings are applied to coiled sheets of metal before it is formed, while extrusion coatings are spray applied after the aluminum extrusion has been formed.
What are the types of coil coating?
Two key types of coatings used for coil coating include: Liquid paints. Powder coatings….There are 4 main film types:
- Polyvinyl chloride (PVC)
- Polyvinyl fluoride.
- Thermoplastic acrylics and.
- Polyethylene terephthalate (PET)
What is difference between PPGI and PPGL?
PPGI is short for pre-painted galvanized steel, while PPGL is short for pre-painted galvalume steel. As the name suggests, PPGI uses galvanized sheets (with a layer of zinc coating) as base metal. While PPGL is with galvalume sheet as substrate, which is coated with 55% aluminum, 43.3% zinc, and 1.6% silicon.
Which roofing sheet is the best in India?
Polycarbonate roofing sheets Polycarbonate roofing sheets are widely used in industrial and large-scale commercial buildings in India. Their insulation properties and high strength quotient make them suitable for such applications.
How are extrusion coatings applied?
In the extrusion coating process an extruder forces melted thermoplastic resin through a horizontal slot-die onto a moving web of substrate. The resulting product is a permanently coated web structure.
What is crinkle finish?
WeatherXL Crinkle Finish has a textured finish that enhances visual depth and adds a richness to color. Its subtle shading creates a shifting effect by breaking up light, providing some excellent performance characteristics. WeatherXL Crinkle Finish is ideally suited to: Create texture and add visual depth.
Which is better PPGI or PPGL sheet?
The heat resistance of the PPGL sheet is better than that of the PPGI sheet. PPGL sheet can withstand temperatures of 315 ℃. Also, PPGL sheets have better corrosion resistance than PPGI. It is because that the dense layer made of aluminum can prevent the base metal from further eroding.
What is the difference between PPGI and PCGI?
In the case of PPGI, there is a thin coating layer that consists of 18-20 microns, and continuous lines are used in the sheet manufacturing facility, and (check the meaning). In contrast, PCGI is coated with magnetically charged particles, and the thickness is around 0.6-0.8 mm.
What is extrusion process?
Extrusion is a process where a material undergoes plastic deformation by the application of a force causing that material to flow through an orifice or die. The material adopts the cross-sectional profile of the die and if the material has suitable properties, that shape is retained in the final extrudate.
What is air gap in extrusion coating?
Schematic diagram of the extrusion lamination process and final finite element mesh for the simulation. Air gap was defined as the length between die exit and contact line of the film to chill/nip roll. Neck-in was defined as the difference between die width and film width in one side.
How do I reduce the glare on my metal roof?
For a roof that is likely to cause a glare issue for neighbours, choose a darker colour in a Resene CoolColour finish. This will help reduce the glare (vs a white) while minimising heat buildup compared to a standard colour….Resene Galvo-Prime
- All exterior galvanised steel.
- Non-ferrous metals.
What is SDP paint?
JSW Steel pre-painted products are available in a variety of paint systems like Regular Modified Polyester (RMP), Silicon Modified Polyester (SMP), Super Durable Polyester (SDP), Poly Vinyldene Fluoride (PVDF) and Vinyl Coated Metal (VCM).
