您當前的位置:  常見問題
  • 離型力, Release force

    從雙面壓敏膠帶上剝離離型紙所需要的力。通過改變離型劑可以調整離型力,例如改變有機硅的類型。 

    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.


  • 軟膠, Soft adhesive

    相比“硬膠” ,“軟膠” 更容易滲入粗糙和有紋路的表面。

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

    優點(相比硬膠)

    好的浸潤——膠水滲入 粗糙,不平的被粘物表面

    高初粘性

    缺點

    耐溫性膠差

    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)

     

    蜂蜜的例子很明顯地說明非常軟的材料的表現。蜂蜜具有超高的初粘性——立即粘在手指上,但是內聚力卻很低,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.

  • 耐溫性, Temperature resistance

    當膠帶暴露在高溫的情況下可以保持(粘接力,內聚力)不受影響的能力。

    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

    解卷一卷壓敏膠帶所需要的力。雙面膠帶解卷力是膠水和離型紙相互作用的結果。而單面膠帶的解卷力士基材和膠水的相互作用。低而穩定解卷力對于膠帶制程過程中是一個重要的性能。

    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

    膠帶或者膠水的材料在使用后抵抗暴露 在此類環境例如光照(日照,紫外線)和潮濕下的能力。通常丙烯酸膠水表現出良好的耐候性。

    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.
