二、技術(shù)參數(shù)：
?高度：500毫米
?臺(tái)板尺寸（長×寬）：400×300毫米
?重量：30kg
?立柱與夾具夾角：45°
?加荷重量：A大29N A小20N
(20N砝碼一只，5N砝碼一只，2N砝碼一只，1N砝碼兩只)
Technical parameters:
? Height: 500 mm
? Platen size (length × width): 400 × 300 mm
? Weight: 30kg
? Angle between column and fixture: 45 °
? Loading weight: A large 29N A small 20N
(One 20N weight, one 5N weight, one 2N weight, two 1N weights)
三、使用說明：
1，調(diào)三底腳，使臺(tái)板放平。
2，調(diào)整導(dǎo)桿與上夾具所需高度，將把手并9瑣緊。
3，先把試件長端夾緊在上夾具上。
4，再把試件短端夾緊在下夾具上。
5，掛上秤砣和砝碼。
Third, instructions for use:
1. Adjust the three feet to make the platen flat.
2. Adjust the required height of the guide rod and the upper clamp, and tighten the handles 9 tightly.
3. First clamp the long end of the test piece on the upper clamp.
4. Then clamp the short end of the test piece to the lower fixture.
5. Hang the scales and weights.
四、結(jié)構(gòu)原理：
儀器主要有上夾具、下夾具及秤砣砝碼等組成，把被測(cè)試件按規(guī)定固定在上下夾具上進(jìn)行夾緊，掛上tuo及砝碼，使其面紙與石膏芯材的剝離而測(cè)出其粘結(jié)面所占百分比數(shù)據(jù)。
Fourth, the structure principle:
The instrument mainly consists of an upper fixture, a lower fixture, and a scale and weight. The test piece is fixed on the upper and lower fixtures according to the regulations and clamped. The tuo and the weight are hung so that the surface paper and the gypsum core material are peeled off to measure Percentage data of its bonding surface.
五、注意事項(xiàng)：
試件在40℃±2℃的條件下干燥至恒溫后，在測(cè)件長邊距端頭20mm處鋸一條縫，把石膏折斷，但不得破壞另一面的護(hù)面紙，測(cè)定背紙與石膏芯粘結(jié)的試件，鋸縫在試件的背面。將試件固定在護(hù)面紙與石膏芯粘結(jié)試驗(yàn)儀上，在試件沿鋸縫彎折的部分掛上20N荷重（包括夾具質(zhì)量），慢慢松開手使護(hù)面紙剝離，觀察每張板上的兩個(gè)試件護(hù)面紙剝離后的狀況。
Five, matters needing attention:
After the test piece is dried to a constant temperature under the condition of 40 ° C ± 2 ° C, a slit is cut at 20mm from the end of the long side of the test piece to break the plaster, but the other side of the paper must not be damaged. The back paper and the plaster core are measured. The bonded test piece is sawed on the back of the test piece. Fix the test piece on the adhesion tester of the paper and the plaster core, and hang a 20N load (including the weight of the clamp) on the part of the test piece bent along the saw seam. Slowly release your hａnd to peel the paper. Observe each The condition after peeling off the two test pieces from the sheet.
