With the acceleration of social and economic development, most enterprises have gradually increased their attention to product quality. In order to effectively meet the market demand for rubber products, rubber processing and production enterprises should not only pay attention to the quantity of products, but more importantly, to control the quality of products.
First, overview of rubber products
Rubber products are mainly rubber products processed on the basis of natural rubber, which also contains rubber products recycled from waste rubber, this rubber production has gradually exceeded natural rubber, styrene butadiene rubber belongs to one of the largest rubber types. Rubber will produce a certain pungent smell due to heat pressing after processing, and because the rubber raw material has a certain internal force, the internal force of the rubber product can not be immediately eliminated after processing, so this will make the rubber product appear unstable contraction. Therefore, in the early stage of the production of rubber products, the production of rubber products should be scientifically designed to avoid reducing the quality of rubber products. As a hot-melt thermosetting material, rubber will be affected by sulfide type changes in its curing temperature range, which requires reasonable measures to be adjusted in the process of rubber product processing to further reduce the quality difference of rubber types.
Second, the reasons for the quality problems of rubber products in China at present
1, the quality of raw materials is poor
The poor quality of rubber raw materials is the most essential reason for the quality problems of rubber products, because there are still some deficiencies in the collection technology of rubber materials in our country, resulting in the quality of material collection process is difficult to be effectively guaranteed. When cutting rubber trees, the cleanliness of rubber can not be effectively guaranteed, especially in some windy weather, it is easy to lead to pollution of rubber collection, thus affecting its own quality. In addition, because rubber trees are distributed in some southern mountainous areas, the production conditions and transportation conditions in these areas are very poor, resulting in quality problems in the production, transportation, storage and other aspects of rubber, and then affect the quality of subsequent rubber products.
2. Rubber is easy to age
In addition to being susceptible to pollution and quality problems during the collection process, rubber raw materials will also age during storage due to improper handling by relevant management personnel. Rubber aging will not only affect the product quality of rubber products, but also have a serious impact on the use of consumers. The essence of rubber aging problem is due to its own chemical reaction with the environment, due to the relevant managers did not effectively preserve and manage the rubber, resulting in the reaction of rubber with oxygen in the air, changing the rubber's own performance, making it appear a series of problems, such as discoloration, softening and so on. In addition, the reason for rubber aging is also related to temperature, too high or too low temperature will have a direct impact on the performance of rubber materials, but also accelerate the speed of rubber oxidation. To this end, in order to prevent the occurrence of rubber aging problems, it is necessary to require relevant managers to do a good job in the preservation and management of rubber raw materials.
Third, rubber product quality and testing measures
1, rubber low temperature performance test
According to the relevant investigation and research results show that the use of rubber products in the brake is also more, but also often used in the cushion, distributing valve film plate, sandwich valve, O-ring, etc., the use of rubber products in the brake is different, and there are certain differences in the temperature requirements, some brakes require the temperature of rubber products to be at minus 50 degrees Celsius. Even below this temperature, it should be used normally. Quality inspection technicians need to carry out specific tests on the cold resistance of rubber products, and be sure to ensure that rubber products do not leak and other problems at minus 50 degrees Celsius. In addition, some rubber products in the installation of machinery, also need to test its oil resistance, a lot of mechanical equipment need to often on some oil change, to ensure the normal operation of the machinery, but the general natural rubber although has a good low temperature performance, but its oil resistance is poor, and people produce synthetic rubber can meet the needs of modern machinery. When people test its low temperature performance, they can use the rubber low temperature brittleness tester, which is more accurate in detection, people can use this method to detect and eliminate rubber products that do not meet the standard through the form of survival of the fittest.
2, rubber electrical performance test
When testing rubber products, it is not only necessary to test the high temperature resistance and cold resistance of rubber, but also to test its point resistance. Perhaps in the impression of most people, rubber is insulating, but this is not the case, some rubber also has electrical conductivity, so it is also very important to do a good job of insulation and chemical inertness detection. The application range of rubber is very wide, in the electrical and electrical industry is also more common, as a special insulating material, rubber also needs to have anti-ultraviolet and anti-ozone properties, so as to better meet people's needs, in general, conductive rubber is a variety of conductive particles dispersed in rubber made of elastic conductive materials, in its detection, We must pay attention to whether the electrical performance meets the corresponding standard requirements. In addition, the testing of rubber products also includes weather resistance and aging resistance, to ensure that rubber products do not have any pollution and harm to the environment, so that rubber products can achieve sustainable development.
3. Standardize the production process
Because the quality inspection of rubber products is only to track the product and judge the pass rate of the product, but not to essentially control the quality of the product, so in order to improve the quality of rubber products, we must first standardize the production process of the product. Enterprises should be in accordance with the standard mold, formula and other production and production, to ensure that the production and processing of products meet the national unified standards. In this way, the theoretical production of rubber products will enter the reliability stage, so that the quality test of the product will reduce unnecessary trouble and greatly improve the pass rate of the product.
4. Upgrade the traditional detection technology
In order to make the detection effect more accurate, the traditional detection technology can be upgraded and updated, and the quality of rubber products will be improved to a certain extent after the update. Therefore, at this time, rubber product manufacturers can use some additives to carry out reasonable anti-aging control of rubber products, and can take antioxidants, viscosifiers, spacers, etc., to improve the quality of rubber products, further reduce the degree of aging, and enhance the quality of rubber products from the basis. In addition, rubber product production enterprises in the processing process, should also develop the corresponding specification requirements, further enhance the control of the production of rubber products, so that it meets the production specification standards, reduce the impact of differences in production standards on the quality of rubber products. In order to ensure the quality of rubber products from the basis, we can strengthen the quality publicity of rubber products, further enhance the quality awareness of users, expand the scope of quality supervision of rubber products, give full play to the testing role of inspectors and the public, improve the quality of rubber production for life and rubber production for enterprises, and establish the corresponding rubber product inspection department. Check the quality of rubber products.
5. Sample detection technology
At present, there are relatively many enterprises producing rubber products in our country. At this time, in order to effectively control the production quality of rubber products, it is necessary to adopt reasonable detection technology to ensure the quality of rubber products. At present, the relevant departments have analyzed the future development of rubber products production enterprises, and found that the enterprises have not carried out reasonable quality control of rubber products in the analysis process. This will not only affect the development and operation of enterprises, but also reduce the status of enterprises in the hearts of customers, and have a negative impact. Therefore, in order to better control the production quality of rubber products in enterprises, more clear reference standards can be adopted. Some rubber products are not representative, so in the process of rubber product sample testing, it is necessary to start with the raw material of rubber products, track the whole process of raw materials, and achieve a more reasonable product verification. In addition, in the actual production process of rubber products, the products should also be inspected in batches to avoid the existence of products that do not meet the standards in rubber products.
Iv. Concluding remarks

In summary, rubber products are widely used in many industries in China, but because of the special properties of rubber materials themselves, it is difficult to get effective control in the production and processing process, which not only affects the development of rubber processing enterprises, but also has a serious impact on the use of consumers. Therefore, Heideparker attaches great importance to the testing of products, focusing on standardizing the production process, strengthening the quality of inspection personnel and adopting advanced product inspection equipment, so as to improve the quality level and pass rate of rubber products.
