Footnotes 28 2 I. ABSTRACT Pigmented wax/resin fills are made and used by painting conservators to fill losses in oil paintings. It is an ideal material because textures, such as canvas weave, can be impressed into the fills to match the painted surface. The Buffalo State College Art Conservation program employs a successful pigmented wax/resin fill formula that uses beeswax, microcrystalline wax, resin, and pigments. One of the components, Laropal® K-80, a resin, is no longer manufactured. The purpose of this investigation was to research and find an alternative resin that would yield an equal or better wax fill formula. To gain more information, aged pigmented wax samples were examined from a report written by Frederick Wallace. In addition, a questionnaire was emailed to conservators to discover what, if any, wax fills they were using, and in what manner. -

Physiotherapy Department Wax Therapy
Patient Information Physiotherapy Department Wax Therapy What is wax therapy? Paraffin wax bath therapy is an application of molten paraffin wax and mineral oil to parts of the body. The combination of paraffin and mineral oil has a low specific heat which enhances the patient’s ability to tolerate heat better than from water of the same temperature. It is one of the most effective ways of applying heat to improve mobility by heating connective tissues. Wax therapy is mainly used on your hands in a hospital setting. Wax therapy is used to alleviate: Pain and stiffness associated with Osteoarthritis and Rheumatoid Arthritis Fibromyalgia Eczema (a dry skin disorder) Joint stiffness and muscle soreness from a variety of causes, such as following fractures, some minor surgical conditions, ligament sprains and strains What are the benefits of wax therapy? Paraffin wax acts as a form of heat therapy and can help improve circulation, relax muscles and reduce stiffness in the joints. It can also help soften skin and may help reduce swelling. Are there side effects? Paraffin wax is tested in a lab to make sure it’s safe and hygienic to use on the body. It’s completely natural and has a low melting point, which means Patient Information it can be easily applied to the skin at a temperature low enough not to cause burns or blisters. However, if you have very sensitive skin, paraffin wax may cause heat rash. Heat rash results in small red bumps on the skin that can be itchy and uncomfortable. If you have a chemical sensitivity, you may develop minor swelling or breakouts from the wax treatment. -

Impact of Polymer Binders on the Structure of Highly Filled Zirconia Feedstocks

The miscibility of wax with polyethylene and polypropylene is investigated in the molten state via a rheological study, revealing wax full miscibility with high-density polyethylene and restricted miscibility with polypropylene. Mercury porosimetry measurements realized after wax extraction allow the characterization of wax dispersion in both neat organic blends and zirconia filled feedstocks. Miscibility differences in the molten state highly impact wax dispersion in backbone polymers after cooling: wax is preferentially located in polyethylene phase, while it is easily segregated from polypropylene phase, leading to the creation of large cracks during solvent debinding. The use of a polyethylene/polypropylene ratio higher than 70/30 hinders wax segregation and favors its homogeneous dispersion in organic binder. As zirconia is added to organic blends containing polyethylene, polypropylene, and wax, the pore size distribution created by wax extraction is shifted towards smaller pores. -
The Modified Research of Paraffin Material for Machining
2018 7th International Conference on Advanced Materials and Computer Science (ICAMCS 2018) The Modified Research of Paraffin Material for Machining Jin Hua, Minghua Chenb Aviation Maintenance NCO Academy, Xinyang, 464000, China [email protected], [email protected] Keywords: paraffin wax system; stearic acid; toughening agent A; polyethylene; NC machining. Abstract: The materials used in NC machine tools are usually steel, which is of high hardness. The influence factors for paraffin wax system performance are studied, which include the effects of stearic acid, toughening agent A, polyethylene and cooling-down methods. The material is prepared according to a certain proportion of the material by modification, which can be used in the mechanical processing of paraffin composite system to replace the material used in CNC processing. The practical application shows that the paraffin compound system can meet the requirements of NC machining and achieve the goal of energy saving and consumption, which is very effective. 1. Introduction Machining of material is usually using rolled steel. Because of its high hardness and great intensity, beginners easily damage equipment and tools by wrong operation during the process of practice [1-2]. Especially in numerical control machine tools, it always causes large amount of waste materials or even causes some accidents due to programming error and tool error. From the material saving and safety point of view, the paraffin can be used as training materials instead of rolled steel [3]. There are many advantages using paraffin, such as low hardness, low cost, recyclable used repeatedly, and so on. So it does not need cutting fluid in machining process and does not damage the cutter. -
