Abstract:
The present invention relates to improvied materials for fabricating can bodies. In particular, the present invention relates to can tooling components (20) fabricated from whisker-reinforced silicon nitride having from about 5 to about 15 weight percent whiskers with an average diameter of at least about 0.75 micrometers. The material preferably has a thermal expansion coefficient of from about 0.20 to about 0.24. The present invention also provides a method for reducing the trim height of can bodies (30) formed using a can tooling apparatus (20, 40, 50, 60, 70, 80).
Abstract:
Disclosed is a composition and process for cleaning articles contaminated with water insoluble contaminants. The process allows for efficient recycling of components in the system. The wash solution (10) effectively cleans water insoluble contaminants and, upon settling in separation vessel (16), quickly releases contaminants from the wash solution (10). In this manner, the wash solution (10) and components of it can be readily recycled. The composition of the present invention includes between about 1.86 volume percent and about 37.2 volume percent terpene, preferably d-limonene, and between about .14 volume percent and about 2.8 volume percent surfactant.
Abstract:
Disclosed is a process for separating components of liquids in industrial processes for cleaning of articles. The process is directed toward a terpene-based cleaning system including washing and rinsing of contaminated articles and which further includes separating components of used wash and/or rinse solutions into component parts so that terpene components of the solutions can be recycled for further washing and the water component of the solutions can be purified and recycled for rinsing. The method can include filtering a stream directly from the wash solution to avoid fouling of the filter (22). The method also includes using a cross flow filter (26) having a pore size of between about 50 ANGSTROM and about 7,500 ANGSTROM to effectively separate water from remaining components of the contaminated wash solution.
Abstract:
A method for finishing metal surfaces, especially that of metal containers, using a cleaning agent (24) having a substantillay neutral pH is provided. In one embodiment of the invention lubricants and coolants (28) used during container forming processes are cleaned from the surface of metal containers by using a terpene cleaning agent (24) comprising d-limonen, alpha-terpineol, beta-terpineol, alpha-pinene, beta-pinene, alcohols of such agents or mixtures thereof. Surfactants may also be used to aid in the cleaning process. The organic component of the cleaning agent, as well as lubricants, coolants (28) and aqueous components (34), are separated for recycling and reuse. Cleaning metal surfaces according to the method of the present invention has many attendant advantages including decreased roughness and increased reflectivity of metal surfaces, increased mobility on a container production line, and reduced amounts of paint, overcoat and internal coat required to decorate metal surfaces.
Abstract:
A non-caustic oven cleaner comprising a terpene is provided. The terpene is most preferably d-limonene. The oven cleaner further comprises effective amounts of a cleaning surfactant, a foaming agent, a stabilizer, a wetting agent and a viscosity agent. Said oven cleaner is produced by separately pre-mixing the oil phase components and the water phase components and then mixing the oil phase into the water phase. A method for safely cleaning oven residue is provided, comprising heating the oven, contacting the oven cleaner to the interior surfaces of the oven for a specified amount of time, and further rinsing said oven cleaner from the interior surfaces of the oven.
