In many industrial application scenarios, overline silicone oil plays a crucial role. As a commonly used base oil, the viscosity selection of dimethyl silicone oil is particularly important, directly affecting the application effect and production efficiency.

I. Understanding Process Requirements

Firstly, it is essential to clarify the specific requirements of the overline process. For the high - speed production of fine wires, such as ultra - fine conductors in the electronics industry, low - viscosity dimethyl silicone oil is needed. Low - viscosity silicone oil has good fluidity and can quickly and evenly coat the surface of the wire. During high - speed operation, it can promptly form a lubricating and insulating protective layer to prevent the wires from entangling and being damaged by friction, ensuring the continuity of production. On the contrary, for coarse wires and low - speed conditions, a higher - viscosity product can be appropriately selected. It can provide more long - lasting protection, reducing the frequency of adding silicone oil and lowering maintenance costs.

II. Considering Environmental Factors

The working environment temperature has a significant impact on the viscosity of dimethyl silicone oil. In high - temperature environments, the viscosity of silicone oil will decrease. If a model with originally low viscosity is selected, it may lead to insufficient lubrication and insulation performance. Therefore, in high - temperature workshops, high - viscosity silicone oil should be preferred to ensure that it can stably adhere to the wire surface and maintain its performance at high temperatures. In low - temperature scenarios, such as outdoor wire production and storage areas, too high viscosity will make the silicone oil less fluid, making it difficult to evenly apply. Low - viscosity silicone oil can easily cope with this situation, ensuring that the wire is not hindered during low - temperature startup and operation, preventing the wire performance and equipment operation from being affected by the coagulation of silicone oil.

III. Matching Equipment Characteristics

Different overline equipment has different compatibility with the viscosity of silicone oil. Precision overline equipment, with high - precision nozzles and coating devices, needs low - viscosity silicone oil to cooperate. It is conducive to precisely controlling the amount of silicone oil applied, achieving fine coating, and meeting the quality standards of high - end products. Some traditional and large - scale overline equipment, with relatively coarse structures, can use high - viscosity silicone oil. Relying on its good adhesion, it can evenly cover the wire under the simple coating of the equipment, achieving the purpose of protection, without the need for complex and precise control, reducing the cost of equipment modification and upgrade, and ensuring the smooth progress of production. In short, the selection of the viscosity of dimethyl silicone oil needs to comprehensively consider various factors and accurately match the needs of the overline scene in order to give full play to the performance of silicone oil and help produce high - quality wires.
