选择合适的工业粘合剂

An adhesive is a liquid or paste product that allows parts to be joined together. The adhesives used in industry are generally synthetic.

粘合剂广泛用于组装电子产品,汽车,航空,包装,建筑,木材,家用电器,纺织和鞋类领域的零件。

行业中的一些最常用的粘合剂是环氧粘合剂,氰基丙烯酸酯粘合剂和聚氨酯粘合剂。

  • How to choose an industrial or structural adhesive?

    为了为您选择合适的粘合剂,您应该首先检查它是否是compatible with the materialsyou need to put together.

    你也需要考虑周边条件such as the ambient temperature (minimum and maximum), the moisture content, UV exposure, exposure to chemicals such as detergents or acids and dust that could affect the bonding quality.

    You will also need to verify if the adhesive you choose is与压力兼容它将被放置(永久性负载,振动,抗冲击,剪切,弯曲等),特别是其对剥离(拉伸强度)的抵抗力。

    You should also consider whether what you are putting together should be able to be分开或不采取, and if so, how the glue should be dissolved.

    您还必须考虑到工作时间,即,可以修改要粘合在一起的元素的位置的时间,以及最终设置时间,即在组件之前必须等待的时间可以在正常情况下使用。作为一般规则,双组分粘合剂具有比单组分粘合剂更短的工作时间和更短的最终设定时间。氰基丙烯酸酯粘合剂,其设定时间为几秒钟,是确认规则的例外。

    Lastly, you must check that the adhesive you choose符合标准大会受到约束。

  • 你应该什么时候使用环氧粘合剂?

    你可能想要使用环氧粘合剂如果you need an adhesive that offers high mechanical strength, whether it be in terms of impact, shear or peeling. Epoxy adhesives are available in asingle要么双组分format.

    如果使用单组分粘合剂,则在热量下聚合环氧树脂,在100至200℃的温度下。如果要使用这种类型的粘合剂,则优选具有烤箱,感应或红外系统,或者至少用于聚合的热风枪(胶水的干燥和固化),这可能需要30分钟长达2小时。单组分环氧粘合剂可以是焊接的有趣替代品,例如在组装碳化钨工具时。

    如果您没有对聚合的热源来源,则可以使用双组分环氧粘合剂,其具有在室温下聚合的优点,尽管也可以通过热量加速该过程。双组分环氧粘合剂通常用墨盒,用静态混合喷嘴并排,因此您不必自己混合它们。取决于环氧粘合剂,工作时间,也称为“锅寿命”,可以从几分钟到几个小时内变化。重要的是根据所需的特性选择您的环氧粘合剂,例如所需的透明度和灵活性,待组装的部件之间的巨大差距等。

    根据其聚合后的主要特性,环氧粘合剂可分为三种类型:

    • 刚性粘合剂, which offer good shear strength and very good durability. These adhesives are used in particular with rigid substrates and high static charges.
    • Soft(灵活)粘合剂offer good impact and peel resistance, as well as good resistance to low temperatures. These adhesives are used in particular to join different materials that do not have the same expansion coefficient.
    • Strong adhesives,结合了刚性和柔性粘合剂的品质。

    三种类型的环氧粘合剂:

    • 刚性粘合剂
    • 软粘合剂
    • Strong adhesives
  • 你应该什么时候使用丙烯酸粘合剂?

    丙烯酸粘合剂are mainly used for bonding various materials such as plastic, glass or wood to金属。They offer good mechanical resistance, but not as good as epoxy adhesives. Acrylic adhesives are however generally cheaper than epoxy adhesives.

    The setting time of single-component acrylic adhesives is relatively long, around 5 to 30 minutes, but it can be accelerated by heating.

  • When should you use a polyurethane or urethane adhesive?

    聚氨酯粘合剂are widely used in thebuildingindustry, for example for bonding insulation panels. They are veryflexible粘合剂,但与环氧粘合剂相比,提供有限的机械强度,特别是当环境温度很高

    单组分聚氨酯粘合剂通过与环境湿度反应聚合。它们可以用热枪施加以减少聚合时间。如果湿度水平低,最好使用双组分聚氨酯粘合剂。

    氨基甲酸酯粘合剂主要用于粘接或修复橡胶基材料,如潜水服。

  • 你应该什么时候使用氰基丙烯酸酯粘合剂?

    Cyanoacrylate adhesives进来吧液体要么凝胶form. These adhesives are primarily designed for quick bonding and they offer good shear strength. At room temperature, setting is almost instantaneous. The first cyanoacrylate adhesives were liquid adhesives, perfectly suited for bonding rigid materials. There are now variants of cyanoacrylate adhesives in gel form with medium to high viscosity.

    Liquid adhesives can be applied to elements to be assembled by infiltration, they diffuse by capillary action. On the other hand, gels are particularly suitable for vertical surfaces and porous materials.

    Cyanoacrylate glue only adheres to a surface if there ismoisture。因此,如果表面完全干燥,它不会有效,因为它不会形成粘合性。为了解决这个问题,您可以将薄薄的水层涂在表面上以引发硬化。

    氰基丙烯酸酯粘合剂用于粘合金属,玻璃纤维,陶瓷,纸板,橡胶和塑料部件。应注意,对于耐热塑料,优选使用环氧树脂。

    这些粘合剂的缺点是它们仅提供低抗冲击性和低抗性对高温。

  • When should you use a silicone adhesive?

    Silicone adhesivesare柔性粘合剂that offer高阻动态应力良好的封口。They also have goodresistance to solvents,UV高温。然而,它们的机械强度不是很高。

    Single-component silicone adhesives require a high moisture content to polymerize. If the humidity level is low, it is better to use a two-component adhesive.

    High resistance:

    • to dynamic effort
    • to solvents
    • 到紫外线
    • 在高温下
  • 你应该什么时候使用双组分粘合剂?

    Regardless of the type of adhesive,双组分粘合剂有没有的优势依赖周围条件for polymerization and their setting time is well-controlled as long as the mixture is correctly dosed.

    Mixing can be done manually or automatically with the cartridge nozzle. If you are mixing manually, it is necessary to dose each component properly. Some two-component adhesives can generate more or less harmful gas emissions, so it is preferable to use them in well-ventilated areas.

    Advantages:

    • 聚合与周围条件无关
    • 受控凝固时间
