How to deal with the aging phenomenon of silicone sealing ring

2021-06-19 17:02:40

The prevention of aging phenomenon focuses on the correct selection of silicone keys and formula design, plus rigorous production concepts, so as to increase the life of silicone products and play their due special functions. Silicone sealing ring surface treatment, experience shows that the cylinder piston and piston rod surface characteristics of the seal life has a very large impact. When selecting O-ring specifications, the material of O-ring must be determined first. At present, in industrial parts, the material of O-ring in life is NBR nitrile rubber. The compression of the O-ring is generally mainly determined by the hardness and material of the O-ring. If the hardness of the O-ring is 70 degrees, the compression of the O-ring is equal to 20%. Silicone waterproof ring is generally installed in several places, grooves, planes, and convex grooves. The installation method of each product is different. Its stress process will also affect the service life and function of the product. Silicone waterproof ring hardness and softness influence: many times according to the different softness of silicone products can completely change the functionality and structure of the product, so the silicone sealing ring in the use process due to the choice of different hardness after stress, stretching, extrusion and other phenomena, the sealing ring will appear some unavoidable problems. The environmental conditions of the finished silica gel products, over time, cause cracking or hardening, silica gel physical degradation and other phenomena, called aging phenomenon, the cause of aging, there are external factors and internal factors:. 1. External factors: external factors such as oxygen, oxide, ozone, heat, light, radiation, mechanical fatigue, lack of processing, etc. 2. Internal factors: Internal factors include the type of silica gel, the way of molding, the degree of bonding, the type of matching drugs, factors in processing engineering, etc.

In the production process, if the electric welding or polishing treatment of the screen frame is uneven and has burrs, the rubber sealing ring also has shock absorption and buffering effect on the upper and lower screen frames in addition to the actual effect of tightness. If the edge is uneven or the polishing treatment is incomplete during the production and processing of the screen frame, unevenness or burrs will appear, and the continuous friction of the screen frame during the operation of the machine equipment will cause the dense components to crack. What factors will affect the storage time of rubber sealing ring. 1. Sealing ring temperature: 5°C ~ 25°C is the ideal storage temperature. Avoid contact with heat sources and sunlight. Before use, the seal removed from low-temperature storage should be placed in an environment of 20°C. 2. Humidity: The relative humidity of the warehouse should be less than 70% to avoid over-wet or over-dry, and no condensation. 3. Light: Avoid sunlight and strong artificial light sources containing ultraviolet rays. Anti-ultraviolet bags provide better protection. It is recommended that the windows of the warehouse be painted with red or orange paint or film. 4, radiation: to avoid ionizing radiation damage to the seal. 5. Oxygen and ozone: Rubber materials should be avoided from being exposed to circulating air. This can be achieved by packaging, winding, storing in a closed container or other appropriate methods. Rubber sealing ring is not only used for sealing machinery and equipment, but also has a very important function, that is, to reduce the friction and vibration in the middle of the components, and to maintain the machinery and equipment. Silica gel, pc polycarbonate, vulcanized rubber rubber, spring, etc. can be used as hydraulic seals of vibrating screens. According to the investigation, some customers will crack the hydraulic seals when using them, in fact, the reasons for this situation are likely to have several aspects directly below. The quality of rubber sealing rings is not up to standard. At present, a wide range of hydraulic seals are made of silicone raw materials, but the quality of hydraulic seals used by different manufacturers is also different. If the raw materials of hydraulic seals are hard or the quality of silicone keys is not good, the cracking difficulties will occur after the machinery and equipment have been running for a period of time. If such problems often occur, the cost of related spare parts will be increased.

Product characteristics of rubber feet. 1, with a reversible deformation of high elastic polymer material, elastic at room temperature, under the action of a small external force can produce a larger deformation, after removing the external force can be restored to its original state, rubber is a completely amorphous polymer, its glass transition temperature (Tg) is low, the molecular weight is often large, more than hundreds of thousands. 2. Rubber is a hot-soluble thermosetting elastomer, while plastic is hot-soluble and cold-cured. Due to the different types of sulfides, rubber has a considerable difference in the temperature range of its molding and curing. It can even be affected by climate change and indoor temperature and humidity. Therefore, the production conditions of rubber finished products need to be appropriately adjusted at any time. If not, the quality of products may differ. Rubber foot application. It not only provides people with rubber auxiliary products for electrical products, hardware tools, furniture and furniture, medical equipment, light industry and other industrial products used in daily life. Rubber feet are beautiful in appearance, easy to use and have anti-skid, anti-collision, anti-shock, temperature resistance, noise reduction and other functions. With the improvement of people's living standards, rubber feet have been widely used in electronics, electrical appliances, furniture and furniture, hardware tools, sports equipment, metal products, musical instrument products, light industrial products and so on. O-rings are used for hydraulic presses and pneumatic control valves and various industrial equipment and components. Under the required working pressure, temperature and different liquid and vapor substances, they have sealing effects under static data or moving standards. All these people should understand this difference, but do you know how to make O-rings better and give full play to it. Another point is that when the rubber O-ring is not used, everyone should try not to open the initial package of the O-ring to prevent dust or dirt from damaging the O-ring. If the O-ring is to be stored, it should be prevented from being irradiated by the sun or placed around a high-temperature heat source (such as a heating furnace) to prevent the O-ring from embrittling too early. It should be noted that the O-ring sometimes faded during the whole storage process of the silicone key, that is, the surface of the O-ring will cause white powder, but you don't have to worry, it is not easy to cause bad harm to the O-ring.

"What is the best angle of the inclined wall of the silicone key?" This is actually a false proposition. The hand feeling of the silicone key is not simply related to the angle of the inclined wall, but also related to the thickness, the brand and model of the silicone hardness and the stroke of the key. There is also the feeling of silicone keys in everyone's heart, and the meaning they want to express is not necessarily the same. Some may be force, some may be resilience of silicone keys, some may be paragraph feeling, and even people's feeling is surface touching effect, such as PU effect, hand feeling oil effect, and people who are not in this line of work may also be talking about feeling. Special adhesive for silica gel is mainly developed for bonding between silica gel and silica gel. It can be cured at room temperature or heating. The cured product has good softness, smooth surface, good transparency, good gloss, corrosion resistance, aging resistance, cold and heat shock resistance, and has the functions of fixation, insulation, waterproof, oil prevention, dustproof, etc. Silicone keys are environmentally friendly and non-toxic, and conform to export standards. The bonding scope of silicone key glue is mainly used for perfect bonding between silicone products such as silicone adhesive, silicone sealing strip, silicone sealing ring, silicone key, silicone supplies, silicone foaming material, silicone sleeve, silicone kitchenware, etc. (the K-680 is quick-drying silicone glue, which is suitable for bonding with silica gel and silica gel, ABS,PC,PVC, metal, etc. with hardness less than 60 degrees, without treating silica gel, it is possible to bond with this glue). Silicone rubber is a kind of highly active adsorption material, which is an amorphous substance and is made of silicic acid gel. MSiO2 · nH2O is a porous substance with different particle sizes, which is properly dehydrated and has an open porous structure, a large specific surface area (surface area per unit mass), and can adsorb many substances. It is a good desiccant, adsorbent and catalyst carrier. We have carried out anti-mold experiments on the produced silica gel keys. The experiments have proved that the anti-mold silica gel keys can effectively inhibit the growth of mold cells and better protect the equipment.
