Ceramic tile treatment

To avoid the use of gauze screens in a PPR, the catalyst material can have the form of porous plates, similar to ceramic tiles [14]. These plates are positioned in racks. Such a PPR bridges the gap between the PPR with granular catalyst enclosed by screens and the honeycombs or monoliths that are used in off-gas treatment. 

Higher Tg acrylic polymers are used for bonding of ceramic tiles, lamination of aluminum foil or plastic films to paper and wood, and in the treatment of textiles. The lower Tg (tacky) versions of the polymer, where the acrylic component is secondary to the elastomeric-based adhesive component, are used in pressure-sensitive adhesive applications.

U) Non-Faradaic electrochemical methods. Conductometric methods have been extensively used by scientists and conservators for monitoring the content of salts removed during water immersion treatments of ancient tiles and archaeological ceramic remains. In a different manner to IC, this technique provides the total ionic... 

As seen in Table 1.1, forming methods using fine powder feeds have been practised for centuries in the preparation of such products as tiles, bricks and tablets. Brief descriptions of modern forming methods used mainly in the pharmaceutical, powder metallurgy and ceramics fields are given in Table 1.2. Such forming methods are generally outside the scope of the present treatment. Information on these techniques is well documented elsewhere the reader is directed to the references noted in Table 1.2.

At first, high-temperatnre heat treatment technique has been developed. That is, for the glazed tile or ceramic substrates, a mixture dispersion of TiO and SiO sol is coated on the surfaces, and then heated to 600-800 C. With heat treatment, the TiOj layers are sintered, and strongly attached to the surfaces. Figure 4.1 illustrates the process for forming photocatalytic thin film on tile [42]. It is characterized by the fact that the material is sintered for a short time for fixation after it is spray-coated with photocatalyst dispersion to 10 nm fine particles of TiO. The thickness of the photocatalytic thin film is controlled at aronnd 150 nm.
