只有来自铸造尼龙有限公司的尼龙油提供三个等级的自润滑尼龙轴承材料,以满足您的具体应用。尼龙油是一种内置油润滑的铸造尼龙,与其他塑料和传统轴承材料相比,尼龙油具有优越的机械加工性、性能和耐久性。三种等级的尼龙油可用于最苛刻的应用:大多数轴承应用的原始绿色尼龙油;食品级,与食品直接接触的天然尼龙油-FG,以及比原始尼龙油稍高压缩载荷能力的MoS2填充尼龙油-MDX。与其他轴承材料相比,将润滑油封装在尼龙基体中提供了显著的优势:在润滑困难、不可能或不理想(食物接触)的恶劣环境中,与其他等级的尼龙相比,润滑导致摩擦系数降低25%。应用。吸水率降低可提高尺寸稳定性。像黄铜一样容易加工和加工。即使在最恶劣的操作条件下,机油也不会脱落、变干或排出。在尼龙油的制造过程中,润滑油包完全分散在铸造尼龙基体中,使其成为铸件结构的一个组成部分。灰色尼龙油MDX是由二硫化钼填充料配制而成,除了润滑油外,二硫化钼填充料还能提高铸造聚合物的结晶度。这就产生了一种分子间结构更为一致的轴承材料,在物理性能值范围内分布更窄,同时保持了未填充尼龙油的高级摩擦性能。尺寸稳定性与较高的结晶度,所有nycast产品显示出改善的尺寸稳定性相比,挤压尼龙对应。但是尼龙油比常规等级的浇铸尼龙具有更好的尺寸稳定性:它的油滴填补了聚合物无定形结构中的空隙,从而减少了水被吸收到这些区域的空间。水分吸收图显示,尽管吸收速度较慢,但尼龙油稳定在约2.5%的水分含量-不到其他未填充尼龙的水分含量的一半。 Only NYLOIL from CAST NYLONS LIMITED offers three grades of self-lubricating Nylon bearing material tailored to meet your specific application. A cast nylon with built-in oil lubrication, NYLOIL provides superior machinability, performance, and durability compared to other plastic and traditional bearing materials. Three grades of NYLOIL are available to fit the most demanding applications: original green NYLOIL for most bearing applications; food-grade, Natural NYLOIL-FG for direct contact with food, and MoS2 filled NYLOIL-MDX with slightly higher compressive load capabilities than original NYLOIL. The incorporation of an oil lubricant package into the nylon matrix provides significant advantages over other bearing materials: Lubrication results in 25% lower coefficient of friction than other grades of nylon Performs in harsh environments where lubrication is difficult, impossible or not desirable (food contact) Works successfully in marine applications. Reduced water absorption promotes higher dimensional stability. Works and machines as easily as brass. Oil will not spin out, dry out, or drain out, even under the harshest operating conditions. During NYLOIL's manufacturing process, an oil lubricant package is completely dispersed within the cast nylon matrix, making it an integral part of the casting's structure. Gray NYLOIL-MDX is formulated with Molybdenum Disulfide filler, which promotes higher crystallinity in the cast polymer, in addition to the oil lubricant package. This yields a bearing material with more consistent intermolecular structure and generally a narrower distribution within the range of physical property values, while retaining the advanced friction properties of unfilled NYLOIL. Dimensional Stability With their higher crystallinity, all NYCAST products exhibit improved dimensional stability compared to their extruded nylon counterparts. But NYLOIL provides even better dimensional stability than regular grades of cast nylon: Its oil droplets fill gaps in the amorphous structure of the polymer, allowing less room for water to be absorbed into these areas. The moisture absorption graph shows that despite a slow absorption rate, NYLOIL stabilizes at approximately 2.5% moisture content - less than half the moisture content of other unfilled nylons. |

美国出口了世界上三分之二的丝织物
2019-02-22 尼龙绳的用途广泛,包括在军事领域,甚至可以称之为“战争胜利纤维”。今天,我们来说说为什么。 20世纪30年代,美国进口了世界上三分之二的丝织物――其中90%来源于日本。他们将75-80%用于针织品,特别是 |
