Hardness standard of silicone extruded strip

by:Kenna     2021-06-26
The standard for the hardness of silicone extrusion rods. This technology is recognized by the world as a good process for producing extruded products. The characteristic of microwave heating is that heat is directly generated in the object to be heated, instead of being input from the outside as usual, which not only generates heat quickly , And the distribution is uniform, which is beneficial to improve product quality and greatly shorten the heating time. Hot air vulcanization sealing strip: hot air sulfur has developed to strong wind type vulcanization, that is, high temperature, high speed hot air vulcanization (Tmax: 450°C and Vmax: 60m/s) can also achieve the effect of flame pretreatment, and the safety is greatly improved. Introduction to electrical cabinet door self-adhesive sealing strips are made of three types of self-adhesive sealing strips with good elasticity and resistance to compression deformation, resistance to aging, ozone, and chemical effects, and a wide operating temperature range (-40°C to +120°C). Ethylene propylene rubber (EPDM) rubber is foamed and densely compounded. It contains unique metal clamps and tongue buckles, which is strong and durable. It plays a key role in various electrical cabinets. The hardness standard of silicone rubber extrusion strips can be classified into solid core products (round, square, flat cross-section shapes), hollow products and metal rubber composite products according to the cross-sectional shape. Second, the three-dimensional heat aging resistance Ethylene-propylene sealing strips have been tested many times before production. From the experiments, it can be seen that the product can continue to work in a high-temperature environment without aging. Therefore, many companies use the product to improve Work efficiency, so as to get more profits. 2. At the same time, put the silicone rubber sealing strip at high temperature for a period of time (placed on the roof or in a sunny place), the PVC sealing strip will become very soft in a short time, the grease on the surface of the sealing strip will be deposited, contaminated with dust, and Yellowing (oil is easy to absorb soil) seepage, dirty hands; the physical properties of silicone rubber sealing strips have no change, the pressure cooker sealing ring for household use is silicone rubber, which uses the high temperature resistance, non-toxic and environmental protection of silicone rubber Performance: There is no obvious change in physical properties of silicone rubber in a working environment of 200°C. The skeleton sealing strip is co-extruded from dense rubber, foam rubber and steel wire/steel sheet. Also known as EPDM sealing strip (EPDM)-suitable for the special environment of -40℃ -+160℃, it has superior anti-ozone characteristics, anti-ultraviolet characteristics, resistance to chemical solvents, and various physical and chemical performance indicators far exceed Similar products. Among the hardness standards of silicone extrusion strips, metal rubber composite sealing strips account for more than 60%. For rubber sealing strips, the cross-sectional design is very important. The first is the shape and size of the sealing lip. The sealing lips on both sides should be the same, Appropriate force contacts the glass from both sides of the car window glass. Regularly check for cracks and breaks. If you find that the sealing strip is broken, you can find an adhesive to repair it first. The adhesive is specially used for bonding, so it is not difficult to repair the cracks. It is used to maintain the door, window glass, front and rear windows, triangular windows and other parts of the body. Its better maintenance ensures safe and comfortable driving. However, few car owners pay attention to its maintenance, but in fact its maintenance is very It’s important because once it’s aging and damaged, it will cause rain leaks in the cabin and increase the wind noise of the car. Rain leaks can easily corrode the body. We can keep the car sheltered from wind, rain, dust and heat by maintaining it. , The effect of sound insulation, and when the body is shaken and twisted, it also plays a role in buffering, absorbing shock and retaining glass. It also plays a decorative role on the edge of the door and window junction, so the owner must maintain it frequently. what is? The coated sealing strip is a composite product made of four kinds of materials with excellent texture. The tough outer skin not only provides the basic quality guarantee for the coated sealing strip, but also is beautiful and elegant. It is an excellent companion for modern home doors and windows; thermosetting The core, the main component is PU, which is the main material of the coated sealing strip. Its super plasticity and our company's excellent technology can meet the needs of different door and window manufacturers; the internal PP skeleton and the perfect combination of plastic and rubber TPU The fishbone barb design and the classified application of the double-sided tape imported from Germany further perfect the covered sealing strip. It is widely used in the fields of box sealing and building sealing. The cold resistance, heat resistance, foaming, solid, and special properties of different application fields developed and designed by our company can meet the application needs. Installation method of inlaid wooden door sealing strip :Because the width of the saw blade or grooving knife used by each manufacturer when grooving is different, there are usually 4mm, 3mm, 2.5mm, 2.0mm, and most of them are 3mm, which is used in the purchase of seals. Be optimistic about the article.
