橡胶软接头在生产过程中,橡胶软接头成型时,如果经过大压力压制,其因弹性体所俱备之内聚力无法消除,在成型离模时,往往产生极不稳定的收缩,必需经过一段时间后,才能和缓稳定。 Introduction: In the production process of rubber soft joints, if the rubber soft joints are molded under high pressure, the cohesive force of the elastomer can not be eliminated. When the mold is released from the mold, it will often cause extremely unstable shrinkage. After a period of time, it can be moderated and stabilized.

In the production process of soft rubber joints, if the soft rubber joints are pressed under high pressure during the molding process, the cohesive force of the elastomer can not be eliminated. When the mold is released from the mold, it will often cause extremely unstable shrinkage. Only then can it be stabilized. Therefore, at the beginning of the design of a soft rubber joint, it is necessary to carefully calculate the fit regardless of the formula or the mold. If not, the size of the product is likely to be unstable, resulting in a low quality of the product.
Soft rubber joints are hot-melt and thermosetting elastomers, and plastics are hot-melt and cold-set. Due to the different types of sulfide, the rubber soft joint has a considerable gap in the temperature range of molding and curing, which can even be affected by the climate and indoor temperature and humidity. Therefore, the production conditions of soft rubber joints need to be appropriately adjusted at any time. If there is no, there may be differences in product quality.
Soft rubber joints are prone to aging or corrosion due to their rubber characteristics, so we need to inspect and replace them regularly. For example, the problem of cracking or cracking of soft rubber joints. Some small cracks may not be very obvious. After the sun exposure (mainly ultraviolet radiation), our pipes will age over time, and there will be different degrees of cracking damage. If this happens , It needs to be replaced in time. We should try to avoid soft rubber joints in the sun or wind and rain!
It is the deformation and delamination of blisters. If there is a small part of blisters or deformation on the surface, it will not affect the performance of the product. It does not need to be replaced. If there are large blisters, deformation and / or layer separation on the surface of the sphere, sometimes rubber layer separation can be observed. At this time, it is also necessary to replace the rubber soft joint as soon as possible.
Installation of rubber flexible joint models. Any inspection should verify that the installation is correct; there are no excessive errors between the flanges, and the mounting surface to surface dimensions are correct. Check for excessive elongation, excessive compression, and incorrect lateral or angle. If installed
The rubber soft joint is displaced too much due to the incorrect setting. The rubber soft joint should be replaced after adjusting the pipeline to adapt to the existing installation.
Shanghai Luoying Pipeline Equipment Co., Ltd. has more than 20 years of production experience. It has strict quality control from the production of rubber joints to finished products. It also uses special rubber to make special rubber joints, regardless of the choice of raw materials. From the manufacturing process of rubber joints, we have unique experience and solutions to ensure the quality of each rubber joint. However, Shanghai Luoying Pipeline Equipment Co., Ltd. has been a professional manufacturer of rubber joints for many years. Our company can process rubber. The types are also diverse, and the quality of our Shanghai Luoying products conforms to national standards. The rubber joint products sold are accompanied by a supply list and quality inspection report and a company quality inspection chapter.
