This material is obtained in the form of fibers or slags in the production process and is used as a thermal and sound insulation in construction and various industries.\r\nSome features of stone wool include:\r\n1. Thermal insulation: Stone wool has high thermal insulation properties due to its fibrous structure.\r\n2. Sound insulation: This material also acts as a sound insulation and can help reduce the transmission of sounds in buildings.\r\n3. Light weight: due to its light weight, stone wool is suitable for use in buildings and structures that require thermal insulation.\r\n4. Fire resistance: This material is usually heat resistant and can be used as a fire insulator in case of fire.\r\n5. Chemical stability: Rockwool is usually resistant to chemicals and corrosion.\r\nRock wool is used as a common insulation material in buildings, heating and cooling systems, and various industries.\r\n### Application of rock wool in tanks and piping\r\nAs a resistant thermal insulation and high insulation properties, stone wool has many applications in tanks. Some applications of rock wool in tanks are as follows:\r\n1. Thermal insulation: Due to its high thermal properties, rock wool protects the tanks against heat loss and helps to control the internal temperature of the tank. This important feature is used in industries that need to maintain the temperature of the content, such as oil and gas industries.\r\n2. Preventing freezing: In tanks that face cold conditions, rock wool acts as an effective thermal insulation to prevent the formation of ice and freezing of the content.\r\n3. Reduction of heat transfer: through the use of sen wool

Essential oils are usually used in the manufacture of perfumes and cosmetics, soap and shampoo, air fresheners and hygiene products, flavoring food and beverages, and adding aroma to household cleaning products and incense.\r\nTypes of essential oils:\r\nEssential oils are divided into two main categories - edible essential oils and chemical or aromatic essential oils. The second category is non-edible chemical essential oils and they have different ingredients from edible essential oils. Aromatic or chemical essential oils are used for important purposes such as preparation Candles or air fresheners are used.\r\nEssential oils are available in powder-liquid and essential oil form.\r\nEdible essential oils are one of the most widely used essential oils.\r\nOrange flavoring\r\nLemon flavoring\r\nBanana flavor\r\nCoconut flavoring\r\nPineapple flavoring\r\nCherry flavoring\r\nRaspberry flavor\r\nPomegranate flavoring\r\nMango flavor\r\nStrawberry flavor\r\nCinnamon flavor\r\nRose flavoring\r\nApricot flavoring\r\nSaffron flavoring\r\nSour apple flavoring\r\nBlackberry flavoring\r\nChocolate flavor\r\nMilk flavoring\r\nCantaloupe flavoring\r\nCoffee flavoring\r\nCaramel flavor\r\nToffee flavoring\r\nButter toffee flavoring\r\nChocolate toffee flavor\r\nCaramel toffee flavor\r\nPeach flavor\r\nWatermelon flavor\r\nLemon flavoring\r\nPowdered vanilla flavoring\r\nLiquid vanilla flavoring\r\nBarberry flavoring\r\nGrape flavoring\r\nDragon fruit flavoring\r\nSweet apple flavor\r\nPear flavor\r\nMixed fruit flavoring\r\nChewing gum flavoring\r\nCherry flavoring\r\nBerry mix flavoring\r\nPistachio flavoring\r\nBiscuit flavoring\r\nAlmond flavor\r\nCola flavor\r\nRed fruit flavor\r\nBanana apple flavoring\r\nCucumber flavoring\r\nsmoke flavor\r\nTropical flavor\r\nBlueberry flavoring\r\nBlueberry flavoring\r\nKiwi flavor\r\nSeven fruit flavoring\r\nCream flavoring\r\nTutti Frutti Flavor\r\nMojito flavoring\r\nNutella flavoring\r\nHazelnut flavoring

**[RTR capacitor 40KVar 440V\r\n**](https://www.automation24.ir/product-2888/%25D8%25AE%25D8%25A7%25D8%25B2%25D9%2586-%25D9%2585%25DA%25A9%25D8%25B9%25D8% 25A8%25DB%258C-rtr-40kvar-440v)\r\nCapacitor:\r\n\r\nA capacitor is an electrical device that can store electrical charge and electrical energy, in fact, the capacitor in electrical circuits stores electrical energy in an electrostatic field, which is called the capacitive effect.\r\nCapacitor structure:\r\n\r\n1- Conductor plates\r\n\r\n2- Insulation between conductors (dielectric)\r\n\r\nCapacitors are made up of at least two conductor plates that are parallel and there is a layer of air or insulation in between. Capacitor conductor plates are usually made of aluminum, silver, and zinc, and air, paper, mica, plastic, ceramic, aluminum oxide, and tantalum oxide are used as insulating materials between the plates.\r\n\r\n**[Click here to buy the product](https://www.automation24.ir/)**\r\n\r\nUses :\r\nCapacitors have a relatively wide application. Among the uses of capacitors, we can mention timing circuits with resistors, balancing the level of direct voltage changes, and also as a filter in circuits, because capacitors easily pass alternating signals, but prevent the passage of direct signals. Considering that the electric charge is stored in the capacitor, the capacitor can also be used to create uniform electric fields. Capacitors can hold electric fields in small volumes.\r\n\r\nCapacity:\r\nCapacity is a measure of the ability to store electrical energy. High capacity means that the capacitor is able to store more electrical energy and its measurement unit is Farad. 1 farad is a big unit and it is a high capacity specification, so it is customary to use smaller units such as micro farad, pico farad and nano farad in capacitors.\r\nTypes of capacitors:\r\nCapacitors have a lot of variety that we describe the most important types of capacitors that are used today.\r\n1- Variable capacitors and trimmers\r\n2- Ceramic capacitors\r\n3- Mica capacitors\r\n4- Polyester capacitors\r\n5- Paper capacitors\r\n6- Wax and oil capacitors\r\n7- Electrolytic capacitors\r\n8- Tantalum capacitors\r\n9- Mylar capacitors\r\nImportant points in buying a capacitor:\r\n\r\nConsidering the variety of capacitors available in the market, one of the concerns of consumers is always to find a type of capacitor according to their needs, therefore, we will state some of the points that should be considered when buying a capacitor.\r\n\r\n1- Attention to the capacity of the capacitor\r\n\r\n2- Ability to withstand charge and discharge currents\r\n\r\n3- Service life\r\n\r\n4- leakage current\r\n\r\n5- Dimensions\r\n\r\n6- Frequency\r\n\r\n7- Price
