Untuk mencipta elastomer silikon dengan ciri -ciri mekanikal yang tinggi, reaktif, Molekul roket lurus digabungkan dengan ejen silang dan pengukuhan (keanjalan, penyerapan, kekuatan air mata).
Apa itu elastomer silikon?
Elastomer silikon (Q), also known as silicone rubbers, exhibit negligible property loss across the temperature range of 51 to +316C (70 to +600F). When heated with an organic peroxide, such as benzoyl peroxide or 2,4-dichlorobenzoyl peroxide, the unvulcanized polymer (dimethylsilicone gum) is often crosslinked to a usable elastomer.
Silicone Elastomer History
Due to their mineral makeup, silicone rubbers, a recent subset of elastomers, may be separated from organic polymers like rubber, susu getah, and polyurethane, among others. Silicon is the fundamental chemical component of silicone (Si). The Latin word for rock, silex, is whence its name originates. Mostly silicon dioxide SiO2 (often referred to as quartz or silica) and silicates are forms of silicon that naturally occur in combination. They make silicon the second most prevalent chemical element (after oxygen) and the most significant chemical base for natural compounds. Together, they account for 25.8% of the weight of the whole crust of the planet.
- Jöns Jackob Berzelius, a Swedish scientist, was the first to successfully separate silicon on his own in 1823 by processing potassium silicofluoride (K2SiF6) with too much metallic potassium.
- J.F. Hyde conducted the initial study to create silicones for commercial use in 1930.
- James Wright, a GE engineer, was seeking for an alternative to rubber in 1949. Silly Putty was created when he combined silicone oil and boric acid, and it was later marketed.
- Neil Armstrong left the first lunar footprint in 1969 while wearing boots with silicone soles.
- The first silicone hydrogel contact lenses were created in 1990, and today, in the twenty-first century, silicones are utilized in a wide range of products, including shampoo, culinary molds, smart phone screen coverings, microprocessors, and solar panels.
Sifat elastomer silikon
Aplikasi berprestasi tinggi, terutamanya dalam situasi bermusuhan di mana bahan polimer konvensional mungkin gagal, memerlukan elastomer silikon. Komponen getah elastomer silikon memberikan ketahanan dan kebolehpercayaan yang tahan lama walaupun tertakluk kepada julat suhu yang luas (dari -50 ° C hingga 250 ° C) atau keadaan luaran yang keras (kelembapan, UV, Ozon).
Mereka sangat sesuai untuk melindungi dan melindungi peralatan elektronik, termasuk garis voltan tinggi, kerana ciri -ciri dielektrik mereka dan rintangan haba. Barang -barang ini akan terus mempunyai ciri elastomerik mereka, seperti rintangan yang sangat baik untuk merobek dan/atau pemanjangan yang sangat tinggi sebelum pecah (penting dalam acuan, pemodelan dan pembiakan, peralatan dapur, dan lain-lain.).
Selain itu selamat untuk kegunaan manusia dan tahan terhadap suhu tinggi yang diperlukan untuk mensteril, Elastomer silikon sesuai untuk aplikasi perubatan (sentuhan kulit, Peranti perubatan, implan jangka panjang, dan lain-lain.).
Silicone Elastomer Chemical Properties
As a direct result of natural rubber's inability to withstand chemicals, synthetic elastomers were initially developed to accomplish so. Silicone goods have been employed in applications that include chemicals like acetic acids, ammonia gas, sodium sulfate, and more ever since they first entered the market. Akibatnya, it is always recommended to double-check with a customer service professional what sort of silicone rubber is ideal for your application. It is crucial to remember that the various silicone grades have subtle differences on the precise types of chemicals they can withstand. Products made of silicone are suitable for use in industrial settings where chemicals are handled or stored because of their high level of chemical resistance.
Kelebihan elastomer silikon
Key benefits of silicone elastomers include:
- Kualiti:Aplikasi berprestasi tinggi yang memerlukan kesucian melampau adalah sesuai untuk elastomer silikon. Pelbagai kemungkinan kegunaan khusus untuk elastomer silikon dapat diperluaskan lagi dengan menjadikan mereka mematuhi gred makanan.
- Fleksibiliti:Anda boleh dengan mudah dan murah menyesuaikan elastomer silikon untuk memenuhi keperluan prosedur dan prestasi yang berubah -ubah.
- Prestasi:The ability to withstand both hot and cold temperatures is one of the unique characteristics of silicone elastomers, allowing them to retain a low compression set in conditions of severe heat while staying flexible in conditions as low as -40 °C.
Disadvantages Of Silicone Elastomers
Some of the key drawbacks to using silicone elastomers can include:
- Cost:When compared to rubber and other materials, silicone elastomers attract a higher price since they are a luxury product. Examining your budget and your production requirements carefully may be necessary to determine whether this applies to your application.
- Feel:Silicone elastomers might feel a little bit sticky to the touch in their unprocessed state. They seem rougher as a result, and this can make it easier for dust and other debris to stick to them.
- Compatibility:Despite silicone elastomers' superior adaptability, some situations and applications will cause them to perform poorly or react negatively. Before deciding if silicone elastomers are the best choice for you, it will be necessary to carefully assess the chemical environment existing in your operations.
