持粘性測(cè)試儀使用方法：
★水平放置儀器，打開電源開關(guān)，并將砝碼放置在吊架下方槽內(nèi)。
★除去膠粘帶試卷A外層的3～5 圈膠粘帶后，以約300 mm／min的速率解開試樣卷（對(duì)片狀試樣也以同樣速率揭去其隔離層），每隔200mm左右，在膠粘帶中部裁取寬25 mm，長(zhǎng)約100 mm的試樣。除非另有規(guī)定，每組試樣的數(shù)量不少于三個(gè)。
★用擦拭材料沾清洗劑擦洗試驗(yàn)板和加載板，然后用干凈的紗布將其仔細(xì)擦干，如此反復(fù)清洗三次。以上，直至板的工作面經(jīng)目視檢查達(dá)到清潔為止。清洗以后，不得用手或其他物體接觸板的工作面。
★在溫度23℃±2℃，相對(duì)濕度65％±5％的條件下，按圖2規(guī)定的尺寸，將試樣平行于板的縱向粘貼在緊挨著的試驗(yàn)板和加載板的中部。用壓輥以約300 mm/min的速度在試樣上滾壓。注意滾壓時(shí)，只能用產(chǎn)生于壓輥質(zhì)量的力，施加于試樣上。滾壓的次數(shù)可根據(jù)具體產(chǎn)品情況加以規(guī)定，如無規(guī)定，則往復(fù)滾壓三次。
★試樣在板上粘貼后，應(yīng)在溫度 23℃±2℃，相對(duì)濕度 65％±5%的條件下放置20 min。然后將試驗(yàn)板垂直固定在試驗(yàn)架上，輕輕把砝碼連接到加載板上。整個(gè)試驗(yàn)架置于已調(diào)整到所要求的試驗(yàn)環(huán)境下或試驗(yàn)箱內(nèi)。
★持粘性測(cè)試儀按開始鍵開始計(jì)時(shí)。
★到達(dá)規(guī)定時(shí)間后，卸去重物。用帶分度的放大鏡測(cè)出試樣下滑的位移量，**至0.1mm；或者記錄試樣從試驗(yàn)板上脫落的時(shí)間（常用方法）。時(shí)間數(shù)大于等于1h的，以min為單位，小于1h的以s為單位。
持粘性測(cè)試儀標(biāo)準(zhǔn)配置：主機(jī)、砝碼3個(gè)、實(shí)驗(yàn)板6只、標(biāo)準(zhǔn)壓輥一個(gè)
How to use the stickiness tester:
★ Place the instrument horizontally, turn on the power switch, and place the weight in the slot under the hanger.
★ After removing 3 to 5 turns of the adhesive tape on the outer layer of the adhesive tape test paper A, unwind the sample roll at a rate of about 300 mm / min. At about 200 mm intervals, cut a sample with a width of 25 mm and a length of about 100 mm in the middle of the adhesive tape. Unless otherwise specified, the number of samples in each group is not less than three.
★ Scrub the test plate and loading plate with a cleaning material and a cleaning agent, and then dry them carefully with a clean gauze. Repeat this three times. Above, until the working surface of the board is cleaned by visual inspection. After cleaning, do not touch the working surface of the board with your hands or other objects.
★ At a temperature of 23 ° C ± 2 ° C and a relative humidity of 65% ± 5%, according to the size specified in Figure 2, paste the sample parallel to the longitudinal direction of the board to the middle of the test board and the loading board next to it. Use a pressure roller to roll on the sample at a speed of about 300 mm / min. Note that during rolling, only the force generated by the mass of the pressing roller can be used to apply to the sample. The number of times of rolling can be specified according to the specific product situation. If there is no stipulation, it is rolled three times.
★ After the sample is pasted on the board, it should be left for 20 min under the conditions of temperature 23 ℃ ± 2 ℃ and relative humidity 65% ± 5%. The test plate is then fixed vertically on the test stand, and the weight is gently connected to the loading plate. The entire test stａnd is placed in the test environment or test chamber that has been adjusted to the requirements.
★ Hold the sticky tester and press the start key to start timing.
★ After reaching the prescribed time, remove the heavy objects. Measure the downward displacement of the sample with a magnifying glass with indexing, ** to 0.1mm; or record the time when the sample falls off the test plate (common method). If the time is greater than or equal to 1h, the unit is min, and if the time is less than 1h, the unit is s.
Standard configuration of stickiness tester: host, 3 weights, 6 test plates, 1 standard pressure roller
