What are the criteria for measuring the quality of silicone rubber tubes? In life, we can evaluate the advantages and disadvantages of silicone rubber tubes through vision, sniffing and tools, from the appearance of silicon tubes to odors to mechanical testing.

When different silicone rubber tubes are used in different products, the test requirements are different. In general, the quality of silicone rubber tubing is defined by packaging, description, color, odor, tensile testing and aging testing.

1. Outer packaging: The packaging surface is clean and tidy, no pollution, no damage.

2. Marking: The logo is clear and there is no damage. Model, name, weight, manufacturer, date of manufacture, validity, and other basic information should be noted.

3. Instruction manual: The product use instructions should be attached. The instructions should include the following contents:

a, main component, opening time, curing time and other technical parameter information.

b, detailed usage.

c, storage methods and precautions.

4. Appearance: Extrusion silica gel should be pasted, no bubbles, no crust, smooth, no collapse, no foreign matter.

5. Curing conditions: The blade is extruded at least for a length of 10 cm. After curing, a section is cut every 5 mm, and there is no pore in the section.

6. Color: The color should meet the design requirements, and there is no obvious color difference.

7. Odor: No strong pungent odor.

8. Squeezability: The extrusion is smooth and the slurry shape is good.

Physical properties

1. Tensile test: mechanical testing machine ≥ 1.5MPa (except for silica gel with special requirements)

2. Hot and cold cycle: high temperature 60 ° C, 2 h, low temperature 20 ° C, 2 h for one cycle, three consecutive cycles.

3. Water resistance: After soaking for 12 hours with silica gel, there was no significant change.

4. Anti-aging: The test report complies with national standards.

硅橡胶管的优劣衡量标准有哪些

硅橡胶管的优劣衡量标准是什么？在生活中，我们可以通过视觉、嗅探和工具，从硅管的外观到气味，再到机械测试等，来评估硅橡胶管的优缺点。

不同的硅橡胶管应用于不同的产品时，测试要求也不同。一般来说，硅橡胶管的质量是从包装、描述、颜色、气味、拉伸试验和老化试验等方面来界定的。

1.外包装：包装表面干净整洁，无污染，无损坏。

2.标识：标识清晰，无损坏。应注明型号、名称、重量、制造商、生产日期、有效性和其他基本信息。

3.使用说明书：应附上产品使用说明，说明中应包括下列内容：

a、主要成分、开启时间、固化时间等技术参数信息。

b、详细用法。

c、存储方式及注意事项。

4.外观：挤出硅胶应粘贴，无气泡，无结壳现象，光滑，不塌陷，无异物。

5.固化条件：叶片挤压至少一段10厘米，固化完毕后，每5mm切割一段，切片中无气孔。

6.色彩：颜色应符合设计要求，没有明显的色差。

7.气味：没有强烈的刺激性气味。

8.可挤压性：挤出光滑，浆料形状良好。

物理性质

1.拉伸试验：机械试验机≥1.5MPa(有特殊要求的硅胶除外)

2.冷热循环：高温60℃，2h，低温20℃，2h为一个循环，连续三个循环。

3.耐水性：用硅胶浸泡12小时后，无明显变化。

4.抗老化：试验报告符合国家标准。
