Insulating Sheet refers to all sheets used for the purpose of separating or blocking the influencing elements between substance A and substance B.
There are a wide range of types, from resin sheets surrounding small electromagnetic coils to construction sheets used as waterproofing underlayment on the roof of a school building.
However, if we are referring to insulating sheets used in industry, equipment, or building construction, we can refer to waterproof urethane sheets with high water repellency, or plastic rubber sheets for electrical isolation, for example. If it is a sheet or separates electricity, a resin rubber sheet or the like is used.
In the construction industry, it is used as a base sheet for waterproofing and water-repellent treatment of flat roofs and roof balconies.
Insulating mats are a kind of foot mat with a carpet or rug material on the surface and an insulating material with electrical resistance, such as fabric rubber or hardened polyurethane, on the backing.
Insulating sheets are often seen in everyday life in household appliances, electrical accessories that use batteries, and toys.
By separating them with a translucent polyester film, the current is cut off and the batteries are kept from being depleted.
Insulating sheets used in health therapy equipment are placed under the treatment chair to prevent the electric current projected from the equipment to the human body from being discharged to the floor.
Since the electricity does not escape under the feet, it is charged to the human body and creates a low-frequency magnetic field. It is believed that the minute amount of 1200 hz current circulating through the body relieves stiff muscles, neuralgia, stiff shoulders, and so on.
That is, once outside of the insulating sheet, the hair that was being pulled by the underlay instantly separates. The current-measuring device will also stop swinging.
So what happens if you drink water while sitting on the seat? It is easy to think that you will receive an electric shock, but you will not receive an electric shock. You can replenish water normally, so there is no need to worry.
Electronic devices are becoming smaller and more powerful as time goes by. At the same time, the challenge is to reduce noise generation and heat generation. The required insulating sheets must have high insulation and thermal conductivity.
Heat-resistant insulating sheets can be realized by using polyimide epoxy resin. The heat resistance is excellent in high temperature range resistance. They are mainly used as a heat-dissipating component for electronic components with high heat generation, such as power devices and LED modules.
The dielectric breakdown strength is estimated to be 70 kV/mm (AC), and the thermal conductivity is 3.5 W/mK.
By mixing polyimide epoxy resin and inorganic filler, an excellent heat-resistant insulating sheet has been developed. Use of this insulating sheet reduces noise generation and heat generation from electronic components.
Insulating tape is not always available in every household. A small number of households that do not use electronics or do DIY have insulation tape. However, there are substitutes for insulation tape that can be found in every household.
These are plastic wrap and vinyl. Batteries fall into the category of things that can be insulated. Batteries include everything from dry cell batteries to lithium-ion batteries and household storage batteries.
In recent years, there has been a sharp increase in the number of ignition accidents from batteries. The cause is a short circuit caused by a conductor connecting the positive and negative terminals of the battery. To be safe, batteries must be insulated.
Wrap or vinyl is a polyolefin-based resin that has insulating properties. By wrapping this around the battery, it can be easily insulated. If you wish to store them, containers made of polypropylene-based resin are recommended.
It is important to handle batteries during storage to prevent serious accidents from occurring. In particular, do not forget the process of insulating them. Even for households that do not have insulation tape, plastic wrap or vinyl is a good substitute.
