Abstract:
A process for drawing wire employing a lubricant comprising perfluorocarbon compounds (PFCs), including aliphatic perfluorocarbon compounds ( alpha -PFCs) having the general formula CnF2n+2, perfluoromorpholines having the general formula CnF2n+1ON, perfluoroamines (PFAs) and highly fluorinated amines (HFAs), and perfluoroethers (PFEs). Such fully and highly fluorinated carbon compounds exhibit a very high degree of thermal and chemical stability due to the strength of the carbon-fluorine bond. Further, because the compounds are fully fluorinated, and therefore do not contain chlorine and bromine, they have zero ozone depletion potential (ODP). Further, because the compounds are photochemically non-reactive in the atmosphere, they are not precursors to photochemical smog and are exempt from the United States Environmental Protection Agency (EPA) volatile organic compound (VOC) definition. Further, because they are volatile, the compounds are easily removed at the end of the process without need for an additional cleaning step. The process provides wire at significantly higher production speeds and longer die life with improved quality and less byproduct debris.
Abstract translation:一种使用包含全氟化碳化合物(PFC)的润滑剂的方法,该润滑剂包括具有通式C n F 2n + 2的脂族全氟化碳化合物(α-PFC),具有通式C n F 2n + 10N的全氟吗啉,全氟胺(PFA) HFAs)和全氟醚(PFE)。 这种完全和高度氟化的碳化合物由于碳 - 氟键的强度而表现出非常高的热和化学稳定性。 此外,由于这些化合物是完全氟化的,因此不含氯和溴,因此它们具有零臭氧消耗潜能值(ODP)。 此外,由于化合物在大气中是光化学非反应性的,它们不是光化学烟雾的前体,并且不受美国环境保护局(EPA)挥发性有机化合物(VOC)定义的限制。 此外,因为它们是挥发性的,所以在过程结束时容易除去化合物而不需要额外的清洁步骤。 该工艺以更高的生产速度和更长的模具寿命提供焊丝,同时改善质量和减少副产品碎片。
Abstract:
A mandrel lubricant for use in the manufacture of seamless tubes is described, which mandrel lubricant is composed of graphite, clay minerals from the class of smectites, a polysaccharide and, if required, a surfactant. The mandrel lubricant is applied in the form of an aqueous dispersion to mandrels which have passed through the cooling bath.
Abstract:
This invention relates to the use of ionic liquids as lubricants in vapor compression systems for cooling or heating. This invention also relates to an apparatus for adjusting temperature that operates a vapor compression cycle.
Abstract:
A stainless steel wire is plated with nickel (Ni) to a thickness of from not less than 1 mu m to not more than 5 mu m. An inorganic salt coat film mainly composed of at least one of potassium sulfate and borax (borate) and free from fluorine (F) or chlorine (Cl) is then deposited on the nickel (Ni) plate 2 as the substrate. The steel wire is then drawn to a reduction of area of not less than 60% to adjust the surface roughness thereof to a range of from 0.80 to 12.5 mu mRz, preferably from 1.0 to 10.0 mu mRz.
Abstract:
본 발명에 따른 방법에 따라서 플라스틱슬라이드층의 제조를 위해 무엇보다도 페이스트가 플라스틱분산물과 충진재로부터 만들어진다. 상기 페이스트는 유기용매를 포함하지 않으며, 소결된 다공성 금속층에 도포된다. 생산된 다층재료는 그다음 소결된다. 유기용매가 사용되지 않으므로 건강상의 위험과 화재의 위험이 경감된다. 더구나 본 발명에 따라 제조된 복합재료는 뛰어난 공동화 내성을 보인다. 베어링과 같이 종래의 윤활제가 없는 적용에 추가하여 이들 복합재료들은 특히 기어펌프 및 충격흡수기에서 결과적으로 사용될 수 있다.
