Cold bond system

Rubber lining by the Cold Bond System three of the four phosphoric acid storage tanks, rubber lined for Madras Fertilizers Limited. These three tanks are each 24 metres diameter and 14.4 metres high perhaps the largest in the world ever to be rubber-lined.

Bonding EPDM membrane with a cold adhesive is appropriate when structures are too light or roofs are steep with curves or sharp corners. Before application of the adhesive, the surface should be made smooth, clean, free from dust, oil, grease or other contaminates which may affect the adherence. This method is economical to cover all types of complex structures even on vertical walls. The sheets can be adhered to smooth surfaces of cement concrete, wood and metallic surfaces made of steel, aluminium, etc. An adhesive bonding system is also suitable for use on rigid insulation and old concrete roofing. 

Trim Line. In the trim shop, the fresh paint surface forms the substrate for a number of bonding operations in which parts prefabricated to a greater or less extent and subsupplied parts are adhesively bonded into the painted body. Because no more bake ovens are involved, cold-curing systems (moisture or two-component systems) are employed. 

Cold Compressive Strength (ASTM C-133). The cold compressive strength of a refractory material is an indication of its suitability for use of refractories in constmction. It is a combined measure of the refractory for the strength of the grains and also of the bonding system. 

Cold Modulus of Rupture (ASTM C-133). The cold modulus of mpture of a refractory material indicates the flexural strength and its suitability for use in construction. It is indicative of the strength of the bonding system of the refractory product. Since the test is done at room temperature, it can only show its... 

The choice of initiator system depends on the polymerization temperature, which is an important factor in determining final product properties. Cold polymers are generally easier to process than hot polymers and in conventional cured mbber parts have superior properties. The hot polymers are more highly branched and have some advantages in solution appHcations such as adhesives, where the branching results in lower solution viscosity and better cohesion in the final adhesive bond. 

Another area of much interest is the adhesion of ice to solids. This system is obviously of much interest in general everyday phenomena (tire friction on road surfaces, ice on metal surfaces, ships, etc.). Especially of interest is the adhesion of ice on ships sailing in the cold areas, and on wings of airplanes. Investigations have shown that the adhesive bonds between clean metal surface and ice are very strong. When the ice is removed by force, it breaks, leaving a thin layer of ice on the solid layer. 

Warm- and cold-dyeing double-anchor dyes are prepared by incorporating halo-triazinyl and vinylsulfonyl reactive anchors. The bond between the triazine ring and a fiber is stable under basic conditions, whereas that to the vinylsulfonyl group is stable to acid. A combination of the two anchor systems therefore produces a dye with... 

Optical excitation of metals with intense femtosecond laser pulses can create extreme non-equilibrium conditions in the solid where the electronic system reaches several thousand degrees Kelvin on a sub-picosecond timescale, while the lattice (phonon) bath, stays fairly cold. As illustrated in Figure 3.22, photoexcited hot electrons may transiently attach to unoccupied adsorbate levels and this change in the electronic structure may induce vibrational motions of the adsorbate-substrate bond. For high excitation densities with femtosecond pulses, multiple excitation/deexcitation cycles can occur and may eventually lead to desorption of adsorbate molecules or reactions with co-adsorbed species. After 1-2 ps, the hot electron...
