In modern industry, ABS (acrylonitrile-butadiene-styrene) and PC (polycarbonate) plastics are widely used in a variety of products due to their unique physical properties. However, when these materials come into contact with lubricating grease, cracking problems may occur, which is not only first, but Baoxing briefly introduces the basic characteristics of ABS and PC plastics. ABS plastic is known for its excellent mechanical strength, good toughness and high impact resistance, and is often used in the manufacture of automotive parts, electronic product shells, etc. PC plastics, on the other hand, are widely used in spectacle lenses, smartphone screens, and other products due to their excellent transparency and extremely high impact resistance.
Analysis of the cause of rupture
1. Chemical compatibility: The chemical composition in some lubricants may not be compatible with the chemical structure of ABS or PC plastics. These components can attack the plastic, causing it to soften or weaken its structure, leading to cracks or cracks.
2. Thermal stability: lubricating oil may generate heat during operation. If this heat exceeds the heat resistance limit of ABS or PC plastics, it may cause deformation or deterioration of the properties of the material.
3. Stress concentration and design defects: If there are defects in the design of plastic devices, such as uneven thickness or sharp corners, lubricating oil may penetrate into these weak areas, resulting in stress concentration and then cracks.
4. Aging and oxidation: Long-term exposure to lubricating oil may accelerate the aging process of plastics, resulting in reduced material properties and thus increasing the risk of breakage.
Baoxing lubricants according toabswithpcAfter an in-depth analysis of the causes of plastic breakage. After continuous attempts, the following coping strategies are proposed:
First and foremost, it is crucial to choose a lubricant that is compatible with ABS and PC plastics. Lubricants that may contain offensive chemicals should be avoidedSecondly, the compatibility and durability of the material should be fully considered in the design stage. The durability of the product can be significantly improved by optimizing the design to reduce the stress concentration points;Regular inspections are also important to help identify and repair problems that could lead to breakageSpecial additives or coatings can also be applied appropriately to improve the oil resistance and durability of the plastic, thereby reducing the risk of breakage.
