增加粘合劑涂量普通可進(jìn)步粘合強(qiáng)度，準(zhǔn)繩上只需粘合強(qiáng)度等于原資料纖維本身分離強(qiáng)度即可。過高的粘合強(qiáng)度常常是在楞頂上涂布過多粘合劑的結(jié)果，它將招致瓦楞楞峰與面紙粘結(jié)面過大，使瓦楞楞峰由U形變成矩形，降了楞高，呈現(xiàn)搓板狀外型，結(jié)果使瓦楞紙板的其它性能惡化。
Increasing the amount of adhesive can improve the adhesive strength, and only the adhesive strength is equal to the separation strength of the original material fiber itself. Too high adhesive strength is often the result of coating too much adhesive on the top of the corrugated board, which will lead to too large bonding surface between the corrugated peak and the surface paper, making the corrugated peak from U-shaped to rectangular, reducing the height of the corrugated board, showing the shape of washboard, resulting in deterioration of other properties of the corrugated board.
正常狀況下，瓦楞楞峰面上粘膠寬度為1.5mm,多不超越2mm為宜，淀粉粘合劑用量約為10-15g/m2.粘合強(qiáng)度取樣規(guī)則是取楞長為25mm,寬度為80mm的瓦楞紙板，這就請(qǐng)求在計(jì)算粘合強(qiáng)度值時(shí)停止數(shù)據(jù)處置。
Under normal conditions, the width of the adhesive on the corrugated peak surface is 1.5mm, which is no more than 2mm. The amount of starch adhesive is about 10-15g / m2. The sampling rule of the adhesive strength is to take the corrugated board with the length of 25mm and the width of 80mm, which requires that the data should be stopped when calculating the adhesive strength value.
把80mm寬度中有幾個(gè)楞算準(zhǔn)，同時(shí)乘以每個(gè)楞的長度值25mm,把它變成被測瓦楞紙板試樣所具有的楞的總的長度值。X=L2xQ/L1式中X:-一定長度單位內(nèi)試樣的實(shí)踐楞數(shù)，個(gè)LI:-規(guī)范規(guī)則的不同楞型檢驗(yàn)的單位長度（300mm）L2:-試樣長度值（80mm）Q:-規(guī)范規(guī)則單位長度內(nèi)楞型的數(shù)量（個(gè)）測試結(jié)果，求出算術(shù)均勻值，并按下列公式計(jì)算出粘合強(qiáng)度。
First, calculate several edges in the 80mm width accurately, and multiply the length of each edge by 25mm to change it into the total length of the edge of the tested corrugated board sample. In the formula x = l2xq / L1, X: - the practical number of test pieces in a certain length unit, Li: - the unit length of different test pieces in the standard rules (300 mm) L2: - the value of test piece length (80 mm) Q: - the number of test pieces in the standard rules unit length, the arithmetic uniform value, and the adhesive strength are calculated according to the following formula.
