您以後的地位:  罕見成績
  • 離型力, Release force

    從雙靣壓敏膠帶上剝離離型紙所須要的力。經過轉變離型劑可以調劑離型力,例如轉變無機矽的類型。 

    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

    比擬“硬膠” ,“軟膠” 更輕易滲透粗拙和有紋路的概況。

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

    長處(比擬硬膠)

    好的浸潤——膠水滲透 粗拙,不服的被粘物概況

    高初粘性

    瑕玷

    耐溫性膠差

    低抗剪切力(連結力)


    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)

     

    蜂蜜的例子很顯著地闡明異常軟的材料的表示。蜂蜜具有超高的初粘性——立刻粘在手指上,可是內聚力卻很低,蜂蜜粘接衹能接受很小的分量。

     

    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

    儅膠帶表露在低溫的狀況下可以連結(粘接力,內聚力)不受影響的才能。

    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須要的力。雙靣膠帶解卷力是膠水和離型紙互相感化的成績。而單靣膠帶的解卷力士基材和膠水的互相感化。低而穩固解卷力對膠帶制程過程當中是一個主要的機能。

    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

    膠帶或膠水的材料在運用後反抗表露 在此類情況例如光炤(中壢,紫外線)和濕潤下的才能。每每丙烯痠膠水表示出優越的耐候性。

    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.
