If you need to accurately determine the performance of the gas through the rubber conveyor belt, you can use the gas to make the rubber not expand or corrode, and make the constant pressure stable on the surface of the sample. The basic method is as follows. You can refer to the previous operation of rubber belt steel ball pressing to determine the detailed operation method than before:

　　具體操作要點主要是我們需要保持在恒定的溫度下空氣室,是一個圓形的樣本分為高壓側(cè)和低壓側(cè)連接高壓側(cè)能夠保持恒壓氣藏,低壓側(cè)的透氣性,由于低壓側(cè)體積小,透氣氣室的儀器,測量設(shè)備和恒溫設(shè)備等等;氣室是一個可以發(fā)送樣品的外圍夾緊裝置在密閉條件下,偏高與氣壓計的精度高,低壓端應(yīng)用的困難和容易透氣微孔硬膠圖片,燒結(jié)微孔材料如不銹鋼圓片的填充空間,保持內(nèi)部的體積更小,并支持標本變形,低壓側(cè)是使用小直徑管通過可拆卸連接器連接到毛細管基準刻度線之間的空腔的總數(shù)量不應(yīng)超過規(guī)定的大小,在恒溫設(shè)備可以使用恒溫浴或使用能保持房間空氣溫度和測試溫度差異值在±0.5℃,設(shè)備標準的測試溫度是23℃。

　　The main points of operation are that we need to keep the air chamber at a constant temperature. It is a round sample, which is divided into high pressure side and low pressure side. The high pressure side can keep the gas reservoir at a constant pressure. The low pressure side has small volume. The instruments, measuring equipment and constant temperature equipment of the air chamber. The air chamber is a peripheral clamping device that can send samples under closed conditions, The high side and the high accuracy of the barometer, the difficulties in the application of the low-pressure end and the pictures of porous hard glue easy to ventilate, the filling space of sintered microporous materials such as stainless steel discs, keep the internal volume minimum, and support specimen deformation, the low-pressure side is the total number of cavities connected to the capillary reference scale line through the detachable connector, which should not exceed the specified size, In the constant temperature equipment, the constant temperature bath can be used or the difference between the room air temperature and the test temperature can be kept within ± 0.5 ℃, and the standard test temperature of the equipment is 23 ℃.

　　如果想要測試條件使用溫度接近，一般可以從以下溫度中選擇:40歲,55歲,70,85,100,125,150,175,200,225和250℃,對任何指定的測試或比較測試,允許的溫度偏差在±0.5℃,可以直接從削減或橡膠制品硫化電影,如果有環(huán)形槽空氣室內(nèi),雙方的樣品模邊緣應(yīng)該環(huán)肋,所以相應(yīng)的環(huán)槽的固定空氣室內(nèi),為平面標本。

　　If you want the test conditions to be close to the use temperature, you can generally choose from the following temperatures: 40 years old, 55 years old, 70,85100125150175200225 and 250 ℃. For any specified test or comparative test, the allowable temperature deviation is ± 0.5 ℃. You can directly cut or vulcanize the rubber products from the film. If there is an annular groove air chamber, the edge of the sample mold of both sides should be annular rib, Therefore, the corresponding fixed air chamber of the ring groove is a plane specimen.

　　可以通過適當?shù)囊?guī)范的丁基橡膠“O”型人物,把試樣夾在中間,固定在透氣室內(nèi)保持緊張,為了保證氣密性,夾緊表面在空氣室,很少真空油脂是允許的,但有效的樣品表面可能沒有油,有效樣本表面的測厚儀,把六個不同測量值,精確到0.02毫米的厚度,取算術(shù)平均6分,作為樣本的厚度值,每一個點的厚度值不應(yīng)超過10%的平均厚度值,使用垂直安裝的形式滲透工具注入適量的毛細管液體,然后轉(zhuǎn)動手柄來調(diào)整容器的液位的高度高于毛細管參考范圍關(guān)閉旁路。

　　The sample can be clamped in the middle through the appropriate standard butyl rubber "O" type person, and fixed in the ventilation room to maintain tension. In order to ensure the air tightness, the clamping surface is in the air room, and few vacuum grease is allowed, but the effective sample surface may not have oil. The thickness gauge of the effective sample surface, accurate to 0.02mm, takes the arithmetic average of 6 points, As the thickness value of the sample, the thickness value of each point shall not exceed 10% of the average thickness value. Use a vertically installed penetration tool to inject an appropriate amount of capillary liquid, and then turn the handle to adjust the height of the liquid level of the container higher than the capillary reference range to close the bypass.

　　半月板和基準校準橫切,開始記錄時間與半月板移動相應(yīng)的距離,在測試的過程中,隨時調(diào)整液體瓶的高度,保持平衡液面兩側(cè)的毛細管,透氣性達到穩(wěn)態(tài)時,大約每2分鐘記錄一個相應(yīng)的距離半月板一般5 - 6次,測試時間為10小時,測試后,本文通過對半月板移動距離和時間參數(shù)的研究，得出了橡膠輸送帶的透氣性與輸送帶的準確關(guān)系曲線。

　　The meniscus and the benchmark calibration crosscut start to record the time and the corresponding distance of meniscus movement. During the test, adjust the height of the liquid bottle at any time to keep the capillary on both sides of the liquid level balanced. When the air permeability reaches the steady state, record a corresponding distance every 2 minutes, generally 5-6 times. The test time is 10 hours. After the test, In this paper, through the study of the moving distance and time parameters of the meniscus, the accurate relationship curve between the permeability of rubber conveyor belt and conveyor belt is obtained.
