    Precision Cleaning for Historical Documents

    ICPF Heritage Science Published Journal Article 2021 

    Safe and Effective

    ICPF Abstract (as published)

    The cleaning of particles from smooth and rough paper surfaces using a high-speed CO2 snow jet was investigated. The measurements included characterization of the jet properties, determination of the cleaning efficiency, and evaluation of any possible adverse effects.

    CO2 Technology Improves Bondability

    A manufactured product may require component surfaces to be joined using methods such as gluing, welding, soldering, and coating. The ability of a surface to be cohesively or adhesively joined or bonded to another surface is termed bondability.

    CO2 Improves Surface Wettability

    A manufactured product may require component surfaces to provide fast and uniform spreading and contact of applied (liquids) adhesives, coatings, paints, sealants, underfills, or molten metals. The ability of surface to be wetted by another substance is termed wettability.

    CO2 Application Profile

    CO2 MQCL for Titanium Machining

    Atmosphere. Optimized.


    The past century has witnessed significant advancements in cutting machines, cutting tools, machine controls, processing materials, and cooling-lubrication chemistries. However, surprisingly very little has changed with regards to the application of coolants and lubricants during machining – the machining atmosphere.

    CO2 Improves Surface Cleanliness in Different Ways

    A manufactured product may require components to have a certain maximum level of surface contaminants such as particles and oils to enable wetting, bonding, or machining operations, or to enable assembly, testing, or functional performance of the product. The ability of surface to be cleaned to a pre-determined and desired cleanliness level, efficiently and without damage to the surface or product, is termed cleanability.

    Surface Transformations

    CO2 Changes Surfaces in Different Ways

    The most practical and unique aspect of COprocessing technology is its ability to transform the chemical and physical nature of a manufactured surface, selectively or non-selectively, and in many different ways. Example surface transformations include dirty-to-clean, hot-to-cool, low surface free energy-to-high surface free energy, high outgassing-to-low outgassing, and non-polar-to-polar.

    Contaminant-Constrained Manufacturing Systems

    Surface Contamination Constrains Manufacturing

    Manufacturing systems comprise numerous processes and apparatuses needed to fabricate a product. In addition, manufacturing systems require inputs such as space, energy, materials, labor, and time. Processes include wire bonding, hard metal turning, precision assembly, adhesive bonding, welding, and inspection, among many other examples.

    CO2 Processing Technology 2.2.3

    CO2 Processing System


    The CO2 processing system comprises three components, as follows:

      • Problem: a manufacturing system comprising a manufacturing apparatus and process (i.e., machining, bonding, assembly, fastening, testing) and a manufactured product (i.e., hardware, subassembly, workpiece, substrate) which is constrained in one or more ways by one or more contaminants (product or tool) present before, during, or following the manufacturing process.
