Why can't rubber seals be reused?

Why can't rubber seals be reused?

2021-06-17 17:04:08

Rubber sealing rings are widely used in various industries such as hardware and plastic, silicone keys for water supply and drainage, fire fighting, shipping, pharmaceuticals, household appliances, toys, electronics, sports equipment and sanitary ware. We can see them everywhere in our life and work. However, how to install rubber sealing rings and what precautions are easily ignored by us, while the neglect of details often leads to big problems, therefore, it is necessary for us to understand what are the precautions for the installation and use of rubber sealing rings. 1. Before installation, all parts of the opened hydraulic system should be strictly cleaned, and special tools should be better used to prevent sharp metal edges from scratching fingers. 2. Do not install the wrong direction and damage the lips. If there are scars of more than 50μm on the lips, it may cause obvious oil leakage. 3, no sealing ring can be forced to install, to pay attention to the degree of fit, can not be knocked in with a hammer, but to use special tools to press the sealing ring into the seat hole, and then use a simple cylinder to protect the lip through the spline part, before installation, to apply some lubricating oil on the lip. 4, to prevent extended use, rubber sealing ring of the expiration of the period, the timely replacement of new sealing ring, and to ensure the size of the same, dynamic seal of rubber sealing life is generally 3000~5000h, should be timely replacement of new sealing ring. 5. Avoid using old rubber sealing rings. When using new rubber sealing rings, carefully check the surface quality to make sure that there are no defects such as small holes, protrusions, cracks and grooves, and they are flexible enough before use. The sealing ring should be careful not to deform the rubber sealing ring when loading into the groove. The sealing medium can be considered on the groove and O-ring. If you do not use the rubber sealing ring, try not to open the original packing to prevent the rubber sealing ring from being damaged by dust or falling into the impurities on the surface of the rubber sealing ring. If you want to save the rubber sealing ring, you should try to avoid direct sunlight or placed near the boiler and other high temperature heat sources to avoid premature aging of the rubber sealing ring. During the preservation process, the rubber sealing ring is white powder, so you don't need to worry about it. It will not affect the performance and service life of the rubber sealing ring.

When installing the rubber sealing ring, it is necessary to prevent forced installation and cannot be knocked in with a hammer. Use a utility tool to press the hydraulic sealing ring against the hole edge first, and the product models to be disassembled and replaced should be consistent. The deformation of rubber sealing ring is divided into recoverable deformation and non-recoverable deformation. Recoverable deformation means slight deformation, such as small amplitude twisting, twisting, curling, non-recoverable deformation means serious deformation, such as sealing ring crease, fracture, etc. After the slightly deformed rubber seal ring recovers its shape, it can be used normally without loss of sealing function, while the severely deformed rubber seal ring cannot be used normally even after recovering its shape. Rubber sealing ring stored for a long time, will produce a slight deformation of the phenomenon, how to restore the deformation of rubber sealing ring. 1. Take out the deformed rubber sealing ring, heat a pot of water quickly, and pour it into the container. 2. After pouring boiling water into the container, soak the rubber sealing ring in boiling water. 3. After soaking for a few minutes, take out the rubber sealing ring and pull it by hand. 4. After pulling, it is OK to restore the elasticity, so that the rubber sealing ring will return to its original shape. When it comes to rubber sealing rings, many people are all an impression, that is, they think that its characteristics are O-shaped and round. There is nothing wrong with it. This is indeed one of its major characteristics. Many people think that the operation method of this product is very simple, but the objective fact is that if it is not applied in time, it is likely to cause early damage and damage. Therefore, we must master more things to pay attention to during installation, only then can all normal applications prevent problems. When installing and applying rubber sealing rings, we should pay attention not to apply too much. The service life of general commodities is 3000~5000h h. After exceeding the service life, we should immediately replace the new sealing ring. When replacing the new sealing ring, we should also carefully consider its service performance. Silicone keys should be established without defects such as small round holes, small meat spots, gaps and concave grooves and have sufficient plasticity before everything can be delivered for normal use. When replacing, it is necessary to strictly check the excavation of the sealing ring groove, remove the dirt inside, polish the pipe drainage ditch, and prevent the lip from being reversed or damaged. If the lip is damaged by more than 50μm, it may lead to prominent oil leakage.

Rubber sealing ring is the most common rubber commodity. Their main uses are common, the production process is relatively simple, and many raw materials are applied. The vast majority of O-ring damage is not caused by the design scheme or working pressure of rubber O-ring. A good design scheme is not easy to cause the damage of O-ring, if it only unilaterally increases the working pressure. 1. Reduction and Rashin are the basic elements, because the secret recipe of rubber O-rings is different, and the reduction of rubber O-rings manufactured by different companies is also different from Rashin. Under the standard of long-term reduction, commodities will cause the imagination of reduction of stress relaxation. Such conditions will slowly expand with the change of time. The longer the time, the smaller the reduction and Rashin, resulting in insufficient ductility and leakage of silicone keys. 2. Temperature is a very critical element. Temperature is very critical to the relaxation degree of rubber sealing ring. No matter what kind of rubber raw material, it will accelerate its high temperature embrittlement rate. The higher the working temperature, the greater the vapor shrinkage deformation. When the commodity deformation exceeds 40%, the O-ring will gradually lose its ductility and cause leakage. Rubber sealing ring as a popular product in various industries in recent years, although the scope of its use is very wide, but there are some friends do not understand, rubber sealing ring used in what equipment. Rubber seals with its transparent, smooth appearance, coupled with its resistance to high and low temperature characteristics, and not easy to aging, not easy to deformation advantages, coupled with its resistance to ozone, solubility, sealing ring electrical insulation and other aspects also have a good performance, making rubber seals in chemical, medical, food, electronics, machinery and other industries have a wide range of use. It can be seen that we will come into contact with a lot of rubber seals in our lives. In the automotive industry, rubber seals are used more often, including windshields, doors and windows, body seals that we can see, and cushion parts that we can't see., The potting and sealing of electrical assemblies are all made of rubber seals. Rubber is the material used for sealing rings on household appliances. Rubber films and plastic wrap can be used for the storage of vegetables and fruits. However, sealing strips are still used in the construction industry, such as bathroom brick seams, waterproof bathing utensils, sealing cement joints, sealing doors and windows and other places.

A part of the silicone key on the conductive surface has a conductive function. When the silicone key is pressed, the conductive surface contacts the switch contact on the circuit board. At this time, the switch is closed. When the silicone key is released, the conductive surface is separated from the switch contact, and the switch is opened at this time. (The conductive materials are mostly conductive ink and conductive carbon particles of the silicone key). Exhaust slot When the silicone button is pressed, the air under the inclined wall is removed from the exhaust slot to press the silicone button. When the silicone button is released, the external air flows from the exhaust slot into the inclined wall below, and the button can Bounced up smoothly. The inclined wall of the button can determine the position of pressing and bouncing back the silicone button. Its inclined angle, shape and thickness directly determine the load, feeling and elasticity of the silicone button. The characteristics and application of remote control silicone key products. 1. High temperature resistance: applicable temperature range -40 to 230 degrees Celsius, can be used in microwave oven and oven.. 2. Easy to clean: Silicone products produced by silica gel can be cleaned after rinsing in water, and can also be cleaned in the dishwasher.. 3. Long life: The chemical properties of the silicone material are very stable, and the products made, the silicone keys have a longer life than other materials.. 4. Color diversity: according to the needs of customers, the deployment of different beautiful colors.. 5.

What caused the silicone keys to have no elasticity. First of all, let's take a look at the structural problem of the silicone key: this situation is generally caused by the non-stroke planning of the silicone key or the thick elastic wall planning of the silicone key when the silicone key is planning the structure. the second type of silicone oil pressure molding control is not in place because the silicone raw material is too much or less when the silicone key is pressed into the oil silicone key. 1. Choose a suitable supplier, should not use the price as the only criterion, you can understand the supplier to do which silicone products are more, you can probably determine the supplier to do what kind of silicone products more professional. 2. Pay attention to the size of the company and whether the process is done in the factory. Many customers who seek quotation online cannot see the size of the silicone key of the supplier's factory, while the silicone product factory in the Pearl River Delta is also uneven. At this time, we should not only pay attention to the unit price of the product, but also examine the size of the supplier's factory, so that the supplier can send some videos of workshop equipment, etc. 3. The ownership of the mold on the quotation sheet. The customer mentioned above stepped on this pit. After the silicone key of the custom instrument was opened in another mold, he wanted to adjust the mold and find a supplier to do it again because the delivery date was not on time. However, the supplier of the customer refused to give the mold, and the ownership of the mold was not clearly noted in the contract.
