How to clean the sealing ring using silicone rubber strip for mechanical seal

How to clean the sealing ring using silicone rubber strip for mechanical seal

2020-11-19 11:05:30

What is the role of the main use of silicone rubber on the mechanical seal, commonly used in the mechanical seal of silicone rubber, forming a barrier between the two surfaces to prevent any liquid or gas leakage, silicone rubber is a more compressible material than metal, the use of silicone products more widely, can be used for a variety of surfaces, such as glass and canned jelly. In order for the seal ring to effectively seal any leaks, it needs to be fully compacted to form a complete barrier, thereby forming a pressure seal. This silicone key is why the jar uses an elastomer seal to hold the jam or jelly instead of any other material, because rubber can produce a more hermetic seal. Before the use of rubber, the cork is the main seal used in the container. The rubber of the seal ring is cheaper and more durable. The seal ring also protects the moving parts of the object by rubbing the object against the hard surface and generating a lot of friction. What should the seal do? It is both a barrier between the two surfaces and a seal that protects the contents of the liquid silicone part inside the seal. Although seal ring manufacturers are able to manufacture large quantities of seals for general use, many companies offer the option of customizing seals for unique products. Seals can be used in countless machinery and equipment, but their two main functions are to protect moving parts and seal joints. Products with moving parts are more likely to wear out due to repeated movement of parts, so there is a risk of rapid machine failure. For these products, it is definitely necessary to invest in silicone key manufacturers to customize sealing rings to ensure that your products are better protected from this damage. Fresh-keeping boxes are commonly used storage tools in daily families. However, the only drawback is that after a long period of use, it is easy to hide dirt and dirt between the sealing ring and the groove gap of the glass fresh-keeping box. Some of them will turn yellow, some will have peculiar smell, and even become moldy and black. This not only affects the beauty, but also breeds bacteria and endangers people's health. Can moldy sealing rings be used. 1. You can use toothpicks to pick out the sealing ring from the side of the lid of the crisper and take it off. However, it should be noted that it is not easy to use force when the toothpick is opened. The toothpick is easy to break. Be careful to use force. 2. The rubber button puts the sealing ring and the box cover together into the water added with baking soda (the groove gap of the box cover should also be cleaned), and gently scrubs the groove gap between the sealing ring and the box cover with vegetable melon cloth. 3. If there are black mildew spots and white sealing rings, we can soak them in disinfectant, which will slowly lighen the color of the black spots. silicone rubber professional custom manufacturing manufacturers, to provide you with the best products, silicone products factory in dongguan city custom phone: 0769-86652688-808,

The temperature range of silicone ring is generally -60 ℃ ~ 250 ℃, the hardness range is Shore A25 to 90 degrees, and the cold resistance of O-ring is -20-30 degrees later for ordinary rubber, I .e. silicone rubber still has good elastic silicone product properties at -60-70 degrees. Some specially formulated silicone rubber can also withstand extremely low temperatures, such as low temperature sealing rings, O-ring silicone because of its environmental performance and more and more popular, to understand the knowledge of silicone products, from the silicone raw materials, color: black, brown, green silicone button color, white, red brown, yellow, blue, red, orange, transparent, gray, can also be specified by the customer color. Silicone ring has excellent heat resistance, low temperature elasticity and particularly excellent oxidation and ozone resistance, high air permeability and selectivity to gas permeation through sealing ring, and good electrical insulation performance (silicone ring has low surface energy, hygroscopicity, can play an isolation role, water resistance, but poor water vapor resistance, pressure above 50psi is not recommended, and is compatible with most oils, chemicals and solvents, A liquid silicone rubber like silicone rubber acid and alkali resistance (refers to the acid or alkali water immersion endurance) is good, polar solvent resistance is acceptable, not resistant to alkane hydrogen and aromatic oil. Rubber has been focusing on customization for decades. Customized perfect solutions and providing high-quality services highlight the new generation's pursuit of the new era goal of silicone products factories. Silicone products are mainly used for molded products. What is the use of silicone tube error, the main factors that affect the error of silicone tube are subjective factors and objective factors. 1. Due to the influence of the head temperature, under the same extrusion conditions of the silicone key manufacturer, if the head temperature is too low, the inner diameter of the extruded silicone sleeve becomes larger, and the wall thickness of the silicone hose becomes thinner. When the extrusion temperature is higher, the inner diameter of the silicone hose becomes smaller, and the wall thickness of the silicone hose becomes thicker. 2. Due to the influence of sealing elements and fluidity of the melting point of the extruded material, the fluidity of the material is closely related to the temperature. With the increase of temperature, the apparent viscosity of the material decreases and the fluidity is good. When the temperature of the machine head decreases, the apparent viscosity of the material is higher and the fluidity is poor. Forced extrusion of rubber products makes the pipe blank of the machine head pressure increase and the elastic recovery occurs due to the release of stress, its expansion level is also proportional to the previous pressure, and the poor fluidity of the material makes the material less extruded, resulting in the inner diameter of the silicone hose becoming larger and the wall thickness becoming thinner. With the gradual increase of the temperature of the rubber button, the flow performance of the extruded material in the head is improved, the pressure of the head is reduced, the amount of elastic recovery of the off-mold tube blank is correspondingly reduced, and the extrusion inner diameter is reduced. On the other hand, the extrusion amount of the material increases with the improvement of the flow performance, so that the wall of the silicone hose is thickened.

How to divide the standard of silicone products with heat resistance

How to divide the standard of silicone products with heat resistance

2020-11-14 16:17:07

The heat resistance of rubber products means that rubber products can still adhere to their original functions and utilization values under the influence of high, high and high temperatures for a long time. The heat resistance of rubber products depends on the varieties and types of rubber used. Therefore, when redesigning the formula, silicone products must understand the heat resistance of rubber raw materials. 1. When the temperature requested by the working environment is 70 to 100 degrees Celsius, natural rubber and styrene butadiene rubber are selected individually. 2. When the temperature requested by the working environment is 100 to 130 degrees Celsius, neoprene rubber silicone key rubber, nitrile rubber and epichlorohydrin rubber are selected individually. 3. When the requested temperature of the working environment is between 130 and 150 degrees Celsius, base rubber, ethylene-propylene rubber and chlorosulfonated polyethylene rubber are individually selected, and mechanical gaskets in the shape of O-rings are annular elastic bodies. The cross-sectional sealing ring is circular and is generally fixed in a groove. During the assembly process, it will be compressed by two or more components, thus generating a sealed interface. 4. When the requested temperature of the working environment is between 150 and 180 degrees Celsius, the liquid silica gel is individually selected from acrylic rubber and hydrogenated nitrile rubber. 5. When the temperature requested by the working environment is one hundred and eighty to two hundred degrees Celsius, vinyl silicone rubber and fluorine rubber are selected individually. How to divide the silicone tube standard? According to the production materials, the use environment and the use requirements, the silicone tube can be divided into industrial-grade silicone tube, food-grade silicone tube and sanitary-grade silicone tube. Different types of silicone tube have strict quality division and quality requirements. Due to the special chemical properties and temperature resistance of silicone rubber raw materials, they are widely used in industry, food, pharmaceutical and other industries to transport acid and alkali silicone key manufacturers, solvents and dust, particles and other solids. Industrial silicone tube is mainly the use of silicone tube special high temperature resistance and chemical inertness and aging resistance, can be a long time in the high temperature environment above 200 degrees continuous work, UV resistance, anti aging, usually used to transport industrial materials and seals chemicals, hose using ordinary silicone rubber material, through the extrusion process production. Food-grade silicone hose is made of silicone material that meets food-grade requirements, and peroxide is used for catalytic synthesis to ensure that the produced hose does not fall off. Food silicone rubber hose is a matching hose for food filling, especially alcohol, beverage and edible oil filling. Food silicone hose has good high temperature resistance, tear resistance and bending properties, and can swing for a long time, so it is also an ideal matching hose for peristaltic pumps. Hygienic silicone tube rubber button is a high clean silicone tube, the hose from the raw materials to meet the food hygiene standards, the entire production process needs to be produced in a high clean production workshop, silicone hose is widely used in the health pharmaceutical industry, high clean laboratories, biological laboratories and vacuum weighing and other high-end scientific research projects.

Now the use of this item is very much, but some people will find that sometimes the surface just bought is not smooth enough, which directly affects the use of the effect, in order to deal with this problem, find out the reason is necessary, and then take measures for the original silicone products, then what is the reason for the use of silicone products is not smooth. 1. First confirm whether it is because of the mold. If the mold itself is not smooth, the surface of the foamed silicone rubber strip and other products produced will not be smooth. 2. Check whether the curing agent is added enough. If the amount of curing agent is insufficient, the surface of the product will be cured insufficiently and there will be a sticky feeling. 3. Check whether the curing agent is evenly stirred. If the curing agent is not evenly stirred, there will be sufficient curing and insufficient curing. At the same time, the silicone in the silicone can be applied to electronic devices: bonded to seals, potting glue, gel, insulating coated liquid silicone rubber, thermal conductive glue and other materials, these materials are used to protect the engine control module, the ignition coil is in the ignition module, Power system module, power system, lighting system, various sensors, connections, etc., this is bonded to the sealant, it is used in various silicone product factory control modules as bonding and fixing of components on circuit boards, or auxiliary fixing of large components, such as capacitors, inductors and electric coils, to prevent components from falling off due to vibration, and has the functions of fixing and damping. Silicone sealing strips from silicone key manufacturers have been applied to various industries such as automobiles, doors and windows, cabinets, refrigerators, containers, etc. According to the requirements of different industries, they have successively developed unique automotive sealing strips, mechanical sealing strips, door and window sealing strips and other products. Therefore, they are widely used in sealing industries such as seals, electronics, lighting, pharmaceuticals, chemicals, machinery and equipment, textile and chemical fiber, automobiles, etc. Silicone sealing strips can be applied in many fields, such as the following aspects:. 1. Silicone sealing strips can be applied to the exhaust system shaft seals, spark plugs and ignition wires of rubber products in transportation. 2.

Mold silicone operation method. 1. Silicon (rubber sealing strip manufacturer introduces uniform mixing of silica gel and curing agent: mold (title: mother of industry) silica gel appearance is flowing liquid, component A is silica gel, component B is curing agent, O-ring seal insulation silica gel product thermal silica gel pad, excellent high temperature resistance, silica gel (food grade silica gel) can withstand high temperature of 200 ℃ and can be used for a long time, the raw materials of this product meet SGS standard, through FDA food grade silica gel testing standard, tasteless and nontoxic, the manufacturer's silica gel keys are produced according to the mold, and the color and shape can be customized. For example, 100 grams of silica gel are taken and 2 grams of curing agent are added. Note: silica gel and curing agent must be stirred evenly, if not stirred evenly, the mold will appear a piece has been cured, a piece of no curing seal ring, silica gel will appear drying and curing uneven condition will affect the service life of silica gel mold and turnover times, and even cause the mold scrap condition. 2. Vacuum bubble removal treatment: silicon (after the glue and curing agent are mixed evenly, vacuum liquid silica gel is evacuated to remove bubbles. The vacuuming time should not be too long. Under normal circumstances (under normal circumstances, do not exceed ^ minutes. If the vacuuming time is too long, the silica gel will solidify immediately, resulting in cross-linking reaction, which makes the silica gel become piece by piece and cannot be painted or poured, thus the silica gel product factory wastes silica gel, silicone can only be poured into the trash can, and then take silicone to do it again. Silica gel as the main raw material processing works, known as silica gel products, silica gel is a silica gel properly dehydrated from the particle size of different porous silica gel key manufacturers material, with an open porous structure, can absorb many substances, is a good desiccant, adsorbent and catalyst carrier. First understand the color matching and color matching of silicone products are two different concepts. The color matching of seals is that we first have a target color, then match the color masterbatch according to our experience, match all kinds of color masterbatch in proportion, and then match the color into products close to the target color, while the color matching is to adjust the existing color into rubber products close to the target color. The operation of color matching between the two needs to be based on the lag of color matching, while different color matching needs to draw up the formula from scratch and change the color. For the color matching and color matching of silicone products, the operator must have rich experience in rubber key operation and good color resolution, and he must understand and be familiar with the flexible use of various color masterbatch, moreover, the whole color matching process should be based on the slow transition from light color to dark color, and the corresponding data of the number should be recorded for each color matching.
