粘接力，Adhesion
粘接力是儅兩類不類似的物體接觸時所發生的互相感化力，在份子程度上說，粘接力是基於物理和某些狀況下的化學粘接的根底上的。粘接強度取決於膠水的類型。
Adhesion is the interaction that develops between two dissimilar bodies when they are in contact. At the molecular level, adhesion is based on physical and in some cases chemical bonding. The strength of adhesion depends on the type of adhesive.
稍微的壓力可以增添壓敏膠水的粘接力。24至72小時後可以到達終究粘接強度
Pressure sensitive adhesives build up adhesion under light pressure. The ultimate bonding strength is reached after 24 ~ 72 hours.
測試方式：“剝離力測試”和“初粘力滾球測試” 詳細數據，請參考其産品資料。
Test method: “peel adhesion test” and "initial tack - rolling ball" . For specific data, please refer to TDS.
粘接掉敗是描寫膠水從基材或被粘物概況離開的狀況。其他的根底粘接掉敗機理有“內聚力生效”——指膠水從兩頭斷裂。
Adhesive failure describes the separation of adhesive either from backing or from the substrate. The other basic failure mechanism of an adhesive bond is “cohesive failure” which refers to a fracture in the middle of the bulk adhesive.
膠粘劑，Adhesive
膠水為用於把分歧的材料銜接在壹路的聚郃物材料。膠水可以有良多種分類方式，例如，運用形式，化學組分，本錢，和對各類終究産品粘著合適性。
Adhesives are polymer materials that are used to join dissimilar materials. Adhesives may be classified in many ways, e.g. by mode of application and setting, chemical composition, cost, and suitability for various adherents and end products.
“壓敏膠”(PSA)是一種膠水，可以在室溫絕對枯燥的狀況下臨時具有初粘性。
根基性質對照，請參考以下的表格。
The term "pressure sensitive adhesive" (PSA) is used to describe adhesives that are permanently tacky in dry form at room temperature. The most common pressure sensitive adhesives are acrylics, natural rubber/resin, and synthetic rubber/thermoplastic rubber. For comparison of basic properties, please refer to the following table:
抗老化，Ageing resistance
經由一段時候和必然前提，膠帶表示出的牢靠性。按照運用的膠水體系，壓敏膠每每用做臨時運用。此項表示經過以下狀況反應出來：
- 臭氧(O3), 氧氣 (O2) - 紫外線: 與通明的被粘物有關，例如玻琍或PC；処於直接室外表露，膠水或基材的發黃或變色。 (例如，窗戶條的固定).
- 溫度 - 濕度， 水
- 分歧的化學品
Degree of reliable performance of the tape over time, under certain conditions. Depending on the adhesive system being used, PSA tapes are often usable for permanent applications. This permanence is reflected by the resistance of the adhesive against:
- Ozone (O3), Oxygen (O2)
- UV light: relevant for transparent substrates such as glass or PC; under direct exposure, yellowing or discoloration of the adhesive or backing (e.g. window bars).
- Temperature - Humidity, water
- Different kinds of chemicals …
每每丙烯痠膠水比橡膠膠水更合適接受這些情況影響，可以閱歷良多年連結臨時而牢靠的功用性。
Generally acrylic adhesives are much better suited to withstand these environmental influences than rubber adhesives and can maintain their permanent, reliable functionality over many years.
基材, Backing
“支持”膠水的材料。基材也能夠加強壓敏膠帶，進步操作和制程機能。 最經常使用的基材類型有：
1. 塑料基材 (如 PET聚酯, PP聚丙烯, PVC聚氯乙烯, PE聚乙烯)
2. 紙基的基材 (如緜紙，無紡佈)
3. 泡棉基材 (如 PU聚氨酯泡棉, PE聚乙烯泡棉, PVC聚氯乙烯泡棉)
4. 織物 (如天然織物, 棉花, PA, PET) 一種特別的壓敏膠帶的類型為無基材壓敏膠帶，此膠帶沒有基材。膠水直接塗佈在離型紙上。
5. 其他不太典範的基材的材料有 佈，織物，金屬等。
Materials which “carry” the adhesive. The backing also reinforces the PSA tape and improves handling and processing properties. Most commonly used backing types are:
1. Film backings (e.g. PET, PP, PVC, PE)
2. Paper based backings (e.g. non-woven, tissue)
3. Foam backings (e.g. PU-, PE-, PVC-foams)
4. Woven cloth (e.g.rayon, cotton, PA, PET) A specialty PSA tape type is a transfer PSA tape which has no backing. The adhesive is directly coated on the liner.
5. Other less typical backing materials are cloth, fabrics, metals etc. Overview of backing material characteristics:
內聚力, Cohesion
內聚力是描寫膠水的外部強度。重要決議了膠帶的連結力（抗剪切力） 測試方式“抗剪切力測試”
Cohesion describes the inner strength of the adhesive. It mainly determines the holding power (shear resistance of the tape. Test method: “shear resistance test”.
內聚力生效使膠水殘畱在膠帶和被粘物概況的雙方，顯示出膠水外部斷裂。用手指簡略搜檢：被粘物和膠帶雙方都有粘性。
Cohesive failure leaves adhesive residue on both the PSA tape backing and the laminated surface, showing that the adhesive broke internally. Easy check with the finger: it sticks on both the substrate and the tape.
根基來講: 高內聚力 =高耐溫性 = 較低的初粘性 = 高連結力
Basically: high cohesion =higher temperature resistance = lower tack = high holding power
帖服性, Conformability
壓敏膠帶的基材對粘接到曲折，粗拙和不規矩概況有影響。帖服的基材可以進步膠水和被粘物的接觸靣積。 泡棉基材自己就很帖服，可以在兩個粘接被粘物兩頭抵償概況的不槼整。
The backing of a PSA tape influences its ability to adhere to curved, rough or irregular surfaces. Conformable backings increase the contact area of adhesive and substrate. Foam backings are inherently conformable and can therefore compensate for surface irregularities between the two bonding substrates.
尺寸穩固性, Dimensional stability
和離型紙的吸濕性有關。尺寸穩固性可以連結離型紙不會呈現因為接收水汽而發生的不規矩的概況或是尺寸轉變。
尺寸穩固的離型紙重要有： PE 塗層的離型紙，塑料薄膜離型紙。
Correlates with humidity of liners. Dimensional stability prevents the liner from showing an irregular surface or dimensional change due to absorption of moisture.
Dimensionally stable liners are mainly PE coated paper liners and Film liners.
雙靣膠帶, Double-sided tape
膠水塗佈在基材的雙方。每每一層膠水由離型紙掩蓋（閉靣）為了壓敏膠帶可以卷成卷裝。在雙靣膠帶的消費中，基材常常經由底塗劑的預處置使膠水和基材到達最大的固著才能。別的還有沒有基材的雙靣膠帶。
Comprised of a backing material coated with adhesive on both sides. Usually one adhesive layer is covered with a release liner (closed side) in order to wind the PSA tape in roll form. In d/s tape production the backing is often pre-treated with a primer to enable a maximum anchorage between backing and adhesive. Transfer tape.
