ТЕХНОЛОГИЯ ЭКСИМЕРНОГО МАТИРОВАНИЯ

Новое экологичное решение даже для трехмерной поверхности. Патент на рассмотрении

По мере того как рынок всё в большей степени обращает внимание на тактильные аспекты отделки, такие как мягкая на ощупь поверхность или длительная стойкость к царапинам и истиранию, производители мебельных фасадов и изделий с трехмерной геометрией поверхности и рельефных панелей в целом нуждаются в решении, которое охватывает все стороны и кромки их изделий. Эксимерная сушка способна работать не только с плоскими панелями.

Традиционные эксимерные сушки, такие как Exydry, обрабатывают плоские панели, которые подвергаются процессу коротковолнового УФ отверждения в бескислородной среде. Технология эксимерного матирования обеспечивает получение высококачественных поверхностей с мягким на ощупь покрытием. ЛКМ отверждается таким образом, что получается чрезвычайно глубокое матовое покрытие с очень низким уровнем глянца (не более 5 gloss). Кроме того, достигается востребованный на рынке, стойкий эффект защиты от отпечатков пальцев.

Exydry-Z делает все это и многое другое. Он обрабатывает трехмерные объекты, поэтому кромки мебельных фасадов такие же матовые и такие же прочные, как и поверхность. Эта инновационная эксимерная сушка, разработанная нашими специалистами, делает еще один шаг вперед. Матовость покрытия, достигаемая путем отделки поверхности перед полным отверждением, не превышает 5 gloss по шкале от 0 до 100. Стойкость поверхности панелей, обработанных и высушенных в Exydry-Z, чрезвычайно высока, несмотря на достижение такого низкого уровня блеска.

И мы сделали это решение более экологичным. Количество азота, используемое для полного удаления кислорода по осям X, Y и Z рельефной панели, что обеспечивает матирование всех поверхностей, значительно ниже, чем в обычных эксимерных сушках.

Обладая тремя запатентованными технологиями, эта инновационная система отделывает, например, мебельные фасады окрашиваемые в распылительных автоматах с качающейся кареткой. Конструкция обеспечивает непрерывную подачу фрезерованных панелей через сушку, обеспечивая полное удаление кислорода без остановки производства. В то время как ключевые преимущества связаны с повышением качества отделки и возможностью ее достижения на трехмерных объектах, производственные затраты снижаются за счет оптимизации потребления азота.

Frequently Asked Questions

Which coated materials need drying?

All coated materials need drying. The type, duration and method of drying differ according to the nature and quantity of the applied lacquer.

How many and what types of drying are there?

Mainly two categories: physical and chemical drying. The former is based on hot air, air flow speed and time, while the latter requires a source (typically lamps) to activate some internal components in the lacquer. There are also lacquers that need both of these methods.

What types of oven are there?

There are different types of oven: in-line, vertical and UV. The first two will dry items through a physical process and differ by size, working speed and hold times of the workpieces. UV ovens, on the other hand, are based on a chemical process and their size is smaller. The choice of an oven is determined by the type of lacquer used.

How do I decide which drying technique is the most suitable?

The recommended type of drying depends on the type of product and is normally defined in agreement with the lacquer manufacturer, to ensure the required coating performance over time. The coating cycle, which also includes drying, is then defined with the aim of obtaining the desired final result, reducing the required investment and optimising performance.

What are the advantages of drying?

Let's talk about the advantages of the whole finishing process, which includes lacquer application and drying. The "finished" item ends up with improved resistance and protection from external agents, as well as a better aesthetic presentation.

What is meant by excimer drying?

Excimer drying is a drying process for UV coating products, which allows surfaces to be obtained with truly outstanding deep matt finish and resistance characteristics of the coating film. Normally it is a mixed cycle, which includes the evaporation of the solvents, followed by exposure to a dedicated lamp (an excimer lamp), to end with final UV crosslinking, necessary to definitively "lock in" the obtained result. The oven Exydry-Z ensures a deep matt finish, surface resistance and soft touch effect even on shaped or raised panels.

What is meant by inert atmosphere drying?

Drying in an inert atmosphere is obtained by dramatically reducing the amount of oxygen present in the oven and replacing it with an inert gas, nitrogen. Considering that oxygen is the natural barrier preventing the crosslinking process, this type of drying allows a 40-70% reduction in the quantity of photoinitiator needed to start crosslinking of UV coatings, resulting in significant cost savings. The first inert atmosphere oven on the market is UV-I.

What are the advantages of drying in an inert atmosphere?

In addition to the dramatic reduction in photoinitiator requirements, with the resulting lower cost of lacquers, drying in an inert atmosphere ensures other advantages. The lacquer used is less harmful to the environment. The yellowing effect caused by photoinitiators is less likely. Fewer UV lamps are required to activate crosslinking, resulting in lower energy costs.

How can I measure drying quality?

Different systems can be used to evaluate the drying quality and characteristics to be obtained from the finishing process. For example, if we want to test the final degree of resistance of the treated item, we will use destructive tests, or tests with solvents or with abrasive tools.

What should I expect in terms of consumption?

Mainly, consumption is in the form of electrical power, necessary to operate the fans that blow air or to handle workpieces inside the ovens, but also to power the lamps.

How simple is it to use a drying oven?

Normally drying ovens are rather simple machines, only a few parameters need adjustments and most importantly, these parameters remain stable even when the lacquer colours and/or the shapes of the coated pieces change. No particular skills are therefore required; it is necessary, however, to set the temperatures for the different zones (if any), the air speed and possibly the power of the lamps (if any).

How long does it take to clean a drying oven?

Normally drying ovens are basically maintenance-free, as these machines do not generally get very dirty.

Is a drying oven very maintenance-intensive?

It depends on the type of oven but generally speaking drying ovens are low maintenance. Only vertical ovens, due to their operating mode, require some extra care because of the loads that they have to bear, but all that's required is checking, tensioning and lubricating some of their parts.

Is there any after-sales service available near me?

Our international network of distributors and branch facilities is widespread globally, and most likely, you'll easily find the right contact in your own country. Otherwise, in just a few days we will send spare parts and technicians straight from our headquarters.

Can I easily manage process scheduling including drying?

The entire coating process, or the drying part only, can be managed through recipes, therefore in a very straightforward way.

Are the edges dried, too?

The drying process depends on the type of coating process. If the edges are treated during the work cycle, these will obviously require drying.

Can any oven be associated with any coating process?

Ovens, just like the coating application machines, have specific characteristics. This makes some ovens specifically suitable for some processes, while others are more flexible and able to adapt to different types of application. For example, a vertical oven is specifically intended for raised or shaped doors, but it can also be used for flat ones.

How flexible is the oven?

Each oven is created with a specific objective in mind. Within the scope of these specifications, it is obviously possible to adjust some parameters including temperature, air speed, power of the lamps and lamp distance. The machines are therefore inherently flexible when operating within their design scope.

Can I order spare parts easily?

 Yes. You can order spare parts by email, by phone, but also using cMaster, our dedicated App for ordering spare parts.
