Abstract

The applicability of infra‐red thermography for assessing building façades was studied. Results from the laboratory experiments highlight the importance of the environmental conditions on the accuracy of technique. The thermograms were found effective in showing the simulated anomalies in test samples.

Abstract

Despite many advances during the last decade in both infra‐red sensor and solid state camera technology, until now little headway has been made in the production of cost‐effective semiconductor sensor arrays capable of operating far into the infra‐red. Old ideas, renewed by the capabilities offered by the latest micromachine technology, may change all this. Reviews the problems associated with building such sensor arrays before introducing some interesting new research results.

Abstract

Although cure of paint coatings by radiation is no new phenomenon, there is considerable increased interest in development of industrial processes using radiation curing for a variety of reasons. Before studying the developments in detail, it is worth noting that radiated energy can basically be divided into two categories. In the first category we have ionising radiation which for our purposes includes electromagnetic radiation of wave lengths less than visible light and also accelerated electrons. In the second category is radiation, which is essentially thermal in its effect ranging from infra red through to microwave and radio frequency. The use of these longer wave length radiations, whose effect is essentially thermal, will not be discussed in detail since all coatings which can be cured in normal high temperature ovens are basically capable of cure with such methods. It is worth noting however, that improvement in the design of infra red lamps with peak radiation in the near infra red at around 1200 nanometers has led to speed up in infra red curing which has been particularly useful in cure of alkyd‐amino finishes on heat sensitive substrates such as wood. There is also developing interest in high frequency long wave length radiation, particularly in the area usually referred to as microwave. Here we have penetrative radiation which produces heat effects by what is sometimes referred to as molecular friction. The conversion of the microwave energy into heat depends on the loss factor of the material in question and so the process is most efficient with polar materials such as water. The most likely use of microwave heating is with water based coatings on substrates which will not themselves heat up rapidly, such as non‐polar plastic films.

Abstract

Infra‐red thermal monitoring of drill bit temperatures is just coming into use for laminate drilling. Although not yet in production use, the method has been evaluated, with promising results, in the engineering laboratories of four major manufacturers. In addition, it has been used with excellent results as a research tool during studies of interactions between drill wear, drill temperature, compositions of entry and backup materials, hole quality, and other parameters of the drilling process. This paper will outline the principles of infra‐red thermometry and will then discuss the present and the anticipated applications to laminate drilling.

Abstract

The requirement to test paint arises at every stage in the development and manufacture of coatings though the exact nature of the test procedure varies widely. For example, in the development of a formulation it will be necessary to evaluate changes in the decorative and protective properties of the coating on its substrate, whilst once the product is in production quality control testing will be required. This typically involves rapid evaluation of liquid and dried paint samples to check for conformation to preset limits. A very wide range of techniques are used in these forms of testing though, in general, the equipment and procedures involved are familiar to all paint technologists and include apparatus such as viscometers, glossmeters, colorimeters, hardness testers and artificial weathering machines.
