Conveyor belt manufacturer decomposition determination of coefficient of cold stretched the most detailed steps
This standard is on the cold resistance coefficient meter stretch stretching cold resistance coefficient of determination of Vulcanized rubber conveyor belt manufacturers, suitable for long-term use at low temperatures under tensile condition of rubber products-determination of cold resistance;
Test principle: this test is determination specimen in at room temperature and the low temperature Xia, to, load role Shi determination its elongation value of than, will GB58 Vulcanized rubber stretch performance of determination under standard in the of I type specimen ends stopped to equal length, makes total long becomes 42mm, as this test of standard specimen, also allows using GB528-82 standard in the of other type conveying with specimen also also interception 42mm, specimen from thickness for 2 ± 0.3mm or select thickness for 1 ± 0.2mm of sulfide film Shang for Conference take, Sample cutting direction consistent with calendering, pressing a direction;
Test instrument: stretch cold coefficient determination instrument of Shang, and Xia clip holding Manager of face respectively carved has diamond pattern, recommended used tooth shaped pattern, weights disc of weight should is equal to immersed ethanol in the of Shang clip holding Manager of weight, measurement with ruler of minimum points degrees is unlikely to Yu 1mm, wire rope should straight, and flexible, to excluded wire in stretch Shi of elongation, conveying with manufacturers from test value in the minus with load of wire elongation value, wire elongation value of determination method see company products technology specifications describes or calls technology discussion are can, Insulation containing enough alcohol in the container, to ensure that the specimen is clamped on by tension does not leak a liquid surface, a minimum of less than 1 degree low temperature hygrometer measurement test of medium temperature, immersion is recommended internal standard, immersion depth 150 mm for low temperature thermometer, test, temperature sensing bulb of a thermometer should work with specimens in the same horizontal position;
Test steps: in specimen of work parts printing Shang two article distance for 25 ± 0.5mm of parallel marking, measurement specimen standard from within of thickness, in 5 seconds within will specimen stretch to original standard from of 145% to 155% Hou, makes rubber conveying with in free State Xia parked 15-120 minutes within, in specimen Shang again printing Shang marking, can by new marking to specimen clip in Shang, and Xia clip holding Manager Shang, and will Shang clip holding Manager Department in has through pulley of wire rope end, Xia clip holding Manager solid to card in hard quality rubber Jane of bottom Central, Will loaded good of specimen and hard quality rubber Jane together immersed at room temperature alcohol in the, makes specimen can in 23 ± 2C of temperature Xia parked 3 minutes, while adjustment zero points alignment pointer disc, in instrument of weights disc Shang Yu 1 minutes within plus finished moderate of load, to guarantee specimen 5 minutes within access to original standard from of 90% large 110%, and from plus load Shi up calculation time, records ruler Shang of pointer indicates value, errors be is unlikely to Yu points degrees value of half, dropped load, remove with specimen of clip holding Manager, Parked 15-120 minutes of Shi long, will heat conveying with specimen again loaded into hard quality rubber roller in the, diffuse into has adjusting good temperature of low temperature alcohol in the, makes specimen in test temperature Xia (temperature tolerance for ± l degrees) parked 3 minutes while adjustment zero points alignment pointer, in weights disc Shang plus equivalent of load, role 5 minutes, and from plus load Shi up calculation time, conveying with manufacturers second times records ruler Shang of indicates value, errors is unlikely to Yu points degrees value of half, to ethanol in the plus dry ice of method adjustment temperature, To ensure the test medium temperature uniformity, ethanol should be stirred thoroughly before immersion in specimens, specimen freezing and stretching process, without stirring, nor may you can add dry ice to ethanol.
To provide our customers with the most satisfactory price of conveyor belt, rubber belt products of excellent quality is our eternal promise!

In we of life in the often see various of conveying with, has polyester conveyor belt , and nylon conveyor belt, and ring conveyor belt and so on, which polyester conveyor belt and nylon conveyor belt Commission belonging to strong conveyor belt, strong conveyor belt to its with body thin, strength high, viscous large of features is broad application Yu mine, and coal field, and chemical, and metallurgical, and building, and port, sector, led conveying with market of development. However powerful large conveyor belt manufacturers, quality is uneven, so there a lot of strong voices of conveyor belt question.
In order to better promote strong conveyor belts to the general user, Sealand Industry CO.,LTD improved technology, improving efficiency and quality, to provide users with high-quality strong conveyor belt, maintaining the strong reputation of the conveyor belt.
Sealand Industry CO.,LTD not only to provide you with high quality strong conveyor belt, along with mine conveyor belt, skirt, cotton canvas conveyor belt conveyor belt conveyor belts and conveyor belts and many other accessories, Sealand obtained the national patent of the conveyor, with modern equipment, diversified products, domestic and international market-oriented building first-class rubber manufacturer.
Sealand takes pride in adhering to the principle of customer first, quality good, offering quality products, welcome customers to visit us.

EP conveyor belt, heard the words all very strange? Then it had another name I am sure you know, is that polyester conveyor belt, it is one of the broader application of conveyor belts on the market today. So what advantages it has let the people choose it? It and what are the characteristics? Bo AO conveyor belt manufacturer explaining for you.
EP conveyor belt with normal compared to the conveyor belt, it was better than normal conveyor belt elastic, and high impact resistance, trench is also very good. At the same time it can be a very good knot about transportation costs, but also high quality, low cost of completion of the transport operation. And compared to the PVC conveyor belt: polyester conveyor belts with small length, wet does not reduce the strength of unique advantages. This is particularly important for long-range transport and moist conditions.
Also has a good elasticity, impact resistant polyester canvas, rich in unique flexibility, can absorb shock well. Use good resistance to water and moist environment, strong adhesion of the tape temperature is not reduced, extend the life of the belt. Unique advantages of wet intensity is not reduced.
Said these are you also interested in EP conveyor belt? If you want to learn more about the EP and PVC conveyor belt conveyor belt conveyor belt manufacturer prices to Bo takes pride consultation or order.
