土工布胀破强度测定仪用途及适用标准:

适用于各类土工织物、土工膜及土工复合品,用于测定土工织物胀破强度。符合AB7742-87<<《纺织品胀破强度和胀破扩张度的测定弹性膜片法》;ASIMD3786-80《液压胀破强度试验方法》.

Geotextile burst strength tester uses and applicable standards:

Applicable to all kinds of geotextiles, geomembrane and geocomposites, used to determine the bursting strength of geotextiles. In line with AB7742-87 << 《Determination of bursting strength and expansion expansion of textiles by elastic diaphragm method》; ASIMD3786-80 “Test method of hydraulic bursting strength”.


土工布胀破强度测定仪技术参数:

★夹具:内径为30..5mm的环形,夹具试验过程中夹具内的试样不应滑移或被夹坏

★薄膜:为高弹性人造橡胶薄膜,厚约1.8mm.

★压力表的满量程应满足试验的A大值在压力表满量程的25%-75%范围内、液压系统应能逐步增大薄膜下的液压直至试样胀破,液体压入速率为170ML/min,胀破时应立即停止加压并在此压力下容器内的容积保持不变,以便记录使试样胀破的总压力和在胀破时使薄膜鼓胀的压力.

Technical parameters of geotextile burst strength tester:

★ Grip: a ring with an inner diameter of 30..5mm. The specimen in the clamp should not slip or be damaged during the clamp test.

★ Film: It is a highly elastic synthetic rubber film with a thickness of about 1.8mm.

★ The full scale of the pressure gauge should meet the large A value of the test. In the range of 25% -75% of the full scale of the pressure gauge, the hydraulic system should be able to gradually increase the hydraulic pressure under the film until the sample bursts. / min, the pressure should be stopped immediately when bursting, and the volume in the container remains unchanged under this pressure, in order to record the total pressure that causes the sample to burst and the pressure that causes the film to bulge when it bursts.


土工布胀破强度测定仪试样的制备:

★每项试验的试样应从样品的长度和宽度两个方向上随机剪取,距样品的边缘应等于或大于100mm,送检样品应不小于1延长米或(2m2)

★试样应不含有灰尘、折痕、孔洞、损伤部分和可见疵点。

★对同一项试验剪取两个以上的试样时,应避免它们位于同一纵向和横向位置上,即采用梯形取样法,(如A避免如卷装幅宽较窄)应在试验报告中注明情况

★剪取试样时应满足精度要求。

★剪取试样前,应先有剪裁计划,然后再剪。

★对每项试验所用全部试样,应予以编号。

上述规定适用于各类土工织物,土工膜和土工复合品,但不包括土工格栅等专门用途制品。

Preparation of geotextile burst strength tester samples:

★ Each test specimen shall be randomly cut from the length and width of the sample, the distance from the edge of the sample shall be equal to or greater than 100mm, and the submitted sample shall not be less than 1 extension meter or (2m2)

★ The sample should be free of dust, creases, holes, damaged parts and visible defects.

★ When cutting more than two samples for the same test, avoid them in the same vertical and horizontal position, that is, use trapezoidal sampling method. Situation

★ The accuracy requirements shall be met when cutting samples.

★ Before cutting the sample, there should be a cutting plan before cutting.

★ All samples used in each test shall be numbered.

The above provisions apply to all types of geotextiles, geomembrane and geocomposites, but do not include special purpose products such as geogrids.


土工布胀破强度测定仪操作步骤:

★试验前应检查仪器各部分是否正常,需要时应用标准弹性膜片对胀破仪作综合性能校验,弹性膜片发生明显变形时必须更换。

★将试样覆盖在膜片上,呈平坦无张力状态,用环形夹具将试样夹紧。

★设定液体压入速率为170ml/min,开动机器,使膜片与试样同时凸起变形,直至试样破裂并记录试验时间.

★读出试样破裂瞬间的A大压力,此即试样破裂所需的总压力值。

★松开夹具取下试样,测定用同样的试验时间使薄膜扩张到与试样破裂时相同形状所需的压力,此即校正压力.

★重复以上步骤对其余试件进行试验。

Operation steps of geotextile burst strength tester:

★ Before the test, check whether the various parts of the instrument are normal. When necessary, use a standard elastic diaphragm to check the comprehensive performance of the bursting instrument. The elastic diaphragm must be replaced when it is significantly deformed.

★ Cover the sample with a flat, tension-free state, and clamp the sample with a ring clamp.

Set the liquid indentation rate to 170ml / min, start the machine to deform the diaphragm and the sample at the same time until the sample breaks and record the test time.

★ Read the large A pressure at the moment of sample rupture, which is the total pressure value required for sample rupture.

Remove the sample by loosening the jig, and measure the pressure required to expand the film to the same shape as when the sample ruptures with the same test time.This is the correction pressure.

★ Repeat the above steps to test the remaining test pieces.
