血浆激活

plasma_activation

The process of cleaning and activating a surface prior to applying an adhesive or coating to increase adhesion is a great way to improve the strength of the bond between the base material and adhesive or coating applied to that material. The application of the血浆激活过程可以显着提高产品的可靠性和性能。可靠性的提高导致生产价值流中的废料和制造成本的下降。这就是为什么等离子体激活是制造中的重要组成部分,其中将粘结过程纳入产品。

血浆激活功能原理

What is Plasma Activation?

Activation is the process of changing the wettability or surface energy of a material. When we discuss wettability we are observing the effect or force of a substance and a surface to stay in contact with each other. This force is often governed on a molecular level by a weak electrostatic charge (Van Der Waals forces) or as a chemical bond by the sharing of electron pairs between atoms (covalent bond).

When this surface energy is low, a fluid moves across the material leaving little to no observed residue on the surface. When this fluid dries or cures on the surface in this condition the resulting coating easily loses contact with the surface. When a surface has high surface energy and a fluid is moved across the surface, a film of the fluid is observed coating the surface. When this fluid dries or cures on the surface in this condition the resulting coating has better adhesion to the surface.

聚合物的血浆激活

塑料聚丙烯或p的激活olytetrafluoroethylene PTFE have relatively low surface energy in its natural state. This means the material must be pre-treated before gluing, painting or printing. Conventional activation by increasing surface area by mechanical roughing, priming or using a volatile organic compound (VOC) liquid adhesion promoter can give a slight shift in surface energy.

使用低压等离子体或大气等离子体对塑料激活的血浆激活可增加表面能量。氧或空气等离子体用氧键代替了聚合物的非极性氢键,从而提供了自由价电子,以共价键与粘合剂或涂层,以确保更好的粘附。

金属,陶瓷和玻璃的血浆激活

金属,陶瓷和玻璃的激活也可以通过血浆激活来改善。激活后,这些材料能够与粘合剂和涂层共价键合,从而确保与常规表面制备相比具有更好的粘附性。

在这些材料上的血浆激活必须立即使用胶合,绘画或二级工艺步骤,因为这些材料通常与空气中的氧气或水蒸气反应,从而降低表面能量并减少激活的影响。

血浆激活粉末

激活的应用也可以应用于粉末。粉末激活增加了粉末的表面能,从而增加了粉末状材料混合成液体的能力。当应用于复合固体的制造时,这种粉末激活过程对混合材料的机械性能有重大影响。

血浆蚀刻and Cleaning Strategy for Better Product Quality

血浆激活用途

Improving adhesive bonds

血浆激活增加了粘合剂和基本材料之间粘附的过程,会增加粘合剂和碱物质之间关节中的果皮和剪切。这种粘附方面的优化增加了使用粘合键合法产生的产品的可靠性和质量。

Improving paint adhesion

基础材料的血浆激活以优化油漆粘附力是血浆激活的极大利用。具有低表面能和水性油漆材料之间的粘附能力,而无需使用底漆或粘附启动子,这是制造策略的重大改进。在这种制造方法中使用血浆激活的这种转变是消除粘附启动子成本的可靠方法,这些启动子通常是从制造价值流中挥发性挥发性有机化合物(VOC)。

提高工业涂料的耐用性

Plasma activation can also be used anytime a coating, ink or dye is being used in material that exhibits poor ware performance. Using plasma activation on these types of processes increases the material properties of these coatings which improves the durability in the coating performance. Often, this application of plasma activation can deliver performance advantages not typically realized by other methods.
