  • 离型力, Release force

    从双面压敏胶带上剥离离型纸所需要的力。通过改变离型剂可以调整离型力,例如改变有机硅的类型。 

    Force needed to remove the liner from the covered adhesive layer of the d/s PSA tape. The release force can be adjusted by release agents, such as silicones.


  • 软胶, Soft adhesive

    相比“硬胶” ,“软胶” 更容易渗入粗糙和有纹路的表面。

    Contrary to “hard adhesives” (), “soft adhesives” flow easier into rough and textured surfaces and substrates.

    优点(相比硬胶)

    好的浸润——胶水渗入 粗糙,不平的被粘物表面

    高初粘性

    缺点

    耐温性胶差

    低抗剪切力(保持力)


    Advantages (compared to hard adhesives):

    good wetting – adhesive flows into rough,

    uneven substrates high initial tack (immediate bond)

    Disadvantages:

    lower temperature resistance

    lower shear resistance (holding power)

     

    蜂蜜的例子很明显地说明非常软的材料的表现。蜂蜜具有超高的初粘性——立即粘在手指上,但是内聚力却很低,蜂蜜粘接只能承受很小的重量。

     

    The example of honey shows very clearly how a very soft mass behaves. Honey has “supertack” – it sticks to the finger immediately, but its internal strength is so low that a bond made with honey withstands only little load.

  • 耐温性, Temperature resistance

    当胶带暴露在高温的情况下可以保持(粘接力,内聚力)不受影响的能力。

    Ability of a tape to remain unaffected (adhesion, cohesion) when exposed to higher temperatures. We distinguish between “short term” temperature resistance (seconds to minutes) and “long term” temperature resistance (hours to years) Test method: “temperature resistance”.


  • 解卷力, Unwinding force

    解卷一卷压敏胶带所需要的力。双面胶带解卷力是胶水和离型纸相互作用的结果。而单面胶带的解卷力士基材和胶水的相互作用。低而稳定解卷力对于胶带制程过程中是一个重要的性能。

    Force required to unwind a PSA tape. The unwinding force of d/s tapes is a result of the interaction between adhesive and release liner. In case of s/s tapes it is the interaction between the backing and the adhesive. A low and constant unwinding force is an important property for the processing of an adhesive tape.

  • 耐候性, Weather resistance

    胶带或者胶水的材料在使用后抵抗暴露 在此类环境例如光照(日照,紫外线)和潮湿下的能力。通常丙烯酸胶水表现出良好的耐候性。

    The ability of a material (tape or adhesive) after application to resist exposure to such conditions as light (daylight, UV-light) and humidity. Generally acrylic adhesive tapes display good weathering resistance.
