The test is carried out in accordance with the decision of CB 2794. The test is carried out by using a rotary viscometer, which is NI)I-1 type rotary viscometer, No. 3, and the speed is 12:mi.
4.3 The test is carried out in accordance with the regulations of GB/T2733.
.1 Determination of shear force
4.4.1 Test receiver and environment
This test adopts the following requirements:
5) The speed can be adjusted (100 yuan 1(0)um/min and (2u±10)mm/ain:) The error is not greater than 1% of the range
) The force measuring band should be made of When the test machine is used, the measured force should be within %~8% of the range. The test temperature should be (232) and the adhesive ratio should be (65). 4.4.2 Detailed preparation
The sample preparation should be carried out according to the relevant provisions of the adhesive. There is no such provision. The following method should be used for the preparation. 4.4.2.1
From the core layer of the conveyor belt, any three-layer belt core ball is made into 100ml (longitudinal south! × 15cm (lateral) trial production two pieces will be bonded by hand equal steel wire wheel example called power punching machine or any other type It is similar to the flying equipment, and the surface is not cleaned, and the stomach is kept in a constant temperature dry explosion at 63~u for about 10min: then the adhesive is cooled to the original temperature. 4.4.2.2 Concentrated glue
Lightly adjust the components of the medium and the single components: 85 parts of the quality plate: add 15 parts of the B group, and the sieve glue is 30mm (vertical) × 1.0num (horizontal) on the adhesive surface. The glue is about 5i. The glue layer should be thin and hooked, without leakage, and then it is about 15mint.
4.4.2.3 Curing|| tt||Lay the test piece on the plane with a thickness of (25±1) mm. Apply 40k1/· for 1 minute. Calculate the time at the same time. After the sample is placed in the test environment for the specified time, cut it into 5 test pieces with a width of (25+1) m along the longitudinal direction of the sample. 4.4.3 Calculate the test results to use the
dosage and measure the thickness and latitude of the test joint surface (accurate to 5): Place the sample on the upper and lower clamps, the distance from the clamping point to the overlap is (5±1), open or tensile testing machine and press (2 u+1 () mn/min, the maximum load before the specimen is sheared and the damage type is obtained, and the shear strength (MP) is calculated according to the formula:
Where: P—maximum load outside the test. : R
The width of the specimen is m
The length of the specimen is m.
The test results are expressed as the technical average value of the dynamic type. 4.5 or the determination of the strength
