Surface treatment of glass

Work undergone in this area has looked at tensile and impact properties of a PVC composite filled with hollow glass beads, of three different sizes, and different volume fractions (96). The influence of particle shape and silane coupling agents, for surface treatment of glass beads, on mechanical properties has also been investigated (116, 366). 

The aim of this book is to serve as a centralized information source for anyone who is interested in the surface and electrochemical properties of silicon and its oxides. It will be most useful to the scientists who study the surface phenomena of silicon and to the engineers who design and fabricate silicon-based electronic devices. It can also serve as a general reference for researchers working in the fields of semiconductor electrochemistry and surface science, in which silicon is commonly used as a model material. In addition, it can be useful to the geologists who study rock-water interactions and to the people who work on etching and surface treatment of glasses. 

Silicic acid esters, Si(OR)4, are produced by the reaction of SiCl4 with the appropriate alcohols. The most important representative of this group is tetraethoxysilane (tetraethyl orthosilicate) Si(OC2H5)4, which is used directly, or after hydrolysis to ethylpolysilicates, as a binder for ceramic pastes, for inorganic zinc dust paints (corrosion protection), for the surface treatment of glass and for the modification of silicates. Silicic acid esters are further used for rendering polymer surfaces scratch-resistant. 

This equation was used to estimate the interfacial adhesion in comparison with the acid-base properties of glass fibers in LDPE. The effect of surface treatment of glass beads on their interfacial adhesion to PET was also estimated from a mechanical property measurement. A mathematical model describing the adsorption of polymers on filler surfaces related coupling density to the average area available for coupling between rubber and filler surface. ... 

The glass industry is a traditional big user of Rare Earths, which are used both for the manufacturing of the glass material itself, and also for the surface treatment of glass pieces. 

The chemical reactions occurring are probably similar to those described above for glass (22). Supporting evidence that amino compounds are chemisorbed by metal oxide surfaces has recently been obtained by inelastic tunnelling spectroscopy (23). Further investigations are being carried out to find explanations for the differences observed in the effects of amine surface treatment of glass and of metal on the adhesion of this polyurethane to the substrate.

There is a separate entry in this book dealing with the surface treatment of particulate fillers in plastics, and so the main discussion here will be about the surface treatment of glass fibres.

Surface treatment of textiles, leather, glass, wood, and paper is the second largest application for fluorinated polyurethanes. The coatings are applied in one-step treatment and impart resistance to soil, water, oil, and stains as well as a smoothness to fabrics and leather that resists removal by many cycles of laundering or dry cleaning.52...

Influence of Acid Treatment. The presence of free alkali on the surface of glass and its influence on adsorption and allied phenomena are well known. McBain (17) pointed out the significance of acid treatment of glass vessels to remove the alkali in quantitative treatment of the phenomenon mentioned. The removal of surface alkali caused a marked change in the production of —Az (20). This last effect was studied in Siemens-type vessels, some of which were prewashed with chromic acid and boiling distilled water and dried under vacuum for 24 hours others were used as they were prepared from fresh glass. 

This detailed article reports on the latest developments by three groups of researchers in the field of antibacterial surface treatments for glass, some polymers (such as PE, PP, nylon, and PETP), and porous materials which are carbohydrate-based. The three teams believe their antibacterial treatments will not worsen the increasing problem of bacterial resistance to antibiotics. Full details of the developments are provided.
