Valmet has fused its paper and boardmaking offering to introduce the new OptiTM range of products. The coating includes four different types of chemicals: Leuco Dyes – Leuco dyes can switch between two chemical forms, one of which is colorless. Vapor Deposition We offer three different vapor deposition processes to deliver the coating properties and structures you need on precision parts. About Thermal Paper . The type of coating technology applied is determined by machine process conditions like speed and web width as well as the paper and board quality desired.
Standard thermal paper is similar to regular 20-lb. bond paper. In order for Thermal Paper to be imaged, it needs a static heat source like a hot stylus or more commonly by a dynamic source of heat like a thermal print head.
In order to improve the service life of paper tube mandrels, a hard, extremely wear resistant coating is required. OptiCoat family of coating technology provides innovative solutions for all paper and board grades. Thermal paper is that indicate letter, Top Coating Shape and form by reaction with heat. A&A Coatings offers many solutions to not only prevent this corrosion in the equipment but to repair and recondition corroded or worn out components. Let us now try to understand the process of manufacturing these papers: The surface of the paper is coated with a solid-state mixture of a dye and a suitable matrix. This is accomplished by a row of very fine dots that are heated and cooled as the paper is transported across the print head by a step motor. The dyes used in thermal paper are usually triaryl methane phthalide dyes or … On-site WC-Co-Cr coating systems for callender roll repair. Thermal spray coatings are used to improve friction and wear and, as a result, the life span of machine parts is enhanced.
PrimeCoat Curtain coater. Thermal paper without a top coating is a good choice for uses that do not require the protective benefits of top coating.
The manufacturing and processing of Pulp and Paper is an extremely corrosive process. Both coatings are provided on the same side of the paper. (When you heat Thermal paper furtively by a cigarette lighter, you can see the paper’s color change to Black, Blue and Red, is depend on dye)
Thermal paper is paper that is coated in a certain chemical that, when heated to a certain temperature,causes the material to change colors.

Thermal paper is composed of a base paper, an undercoating and a thermal coating. HVAF & HVOF coating equipment to protect chilled cast iron, thermo and deflection compensated rolls in super-calender, soft and multi-nip-calenders with tungsten carbide coatings. Around 80-90 microns thick (thicker than both regular and
Thermal paper is produced by Coating on Base paper. It is a versatile process that can use a large range of materials starting from pure metals to alloys, carbides, ceramics and even composites. APT thermal spraying Factory is located in Jiangmen City. Thermal spray covering equipment and services for paper machine coater rolls, winder reel drums and cylinders in California, USA. Tungsten carbide/cobalt is among the most wear resistant of the thermal spray materials. Facsimile paper is typical of it. Our thermal spray processes are cost-effective and versatile, helping you protect new and worn parts from wear, corrosion, fatigue, oxidation and high temperatures. When the paper is exposed to heat via a thermal print head, microcapsules in the coating break open to release the dye that creates the image or text.
