What ultrasonic sensor can be used to detect the level of the blowing agent

Foaming agent, also known as styrofoam,which refers to glue with foaming properties and adhesiveness. It is widely used in the filling of window edge joints, expansion joints, and holes. Blowing agents are used in many ways, the most common being used in homes and sometimes in construction. The blowing agent used in these aspects is only a part, and industrial use is the biggest battlefield of blowing agent.

At present, most of the blowing agents on the market are put into the industry, ultrasonic distance sensor mainly used in automobile manufacturing, electrical appliances and toy models. In automobile manufacturing, it can be used in different places according to the type of blowing agent. Because the foaming agent has the effects of sealing, sound insulation and insulation, it is often used in the sealing of automobile parts. In addition, the foaming agent is also used in the manufacture of electrical appliances. Because the electrical appliance needs to be sealed with a foaming agent during the manufacturing process, the foaming agent is a combination of aerosol technology and polyurethane foam technology, so the performance and polyurethane It is the same as styrofoam, as the foaming agent is used to seal precision parts. Because the foaming agent is easy to control in terms of metering, the use of a very small amount of foaming agent can achieve the effect of sealing the electrical appliance, which is making the appliance waterproof, moisture-proof, and insulating And the effect of sealing.

In fact, the composition of the blowing agent is very simple, that is, the polyurethane prepolymer, catalyst, cross-linking agent, etc. are loaded into the high-pressure iron can and then filled with propane and other gases. Its technological process is the production of raw materials-bottle preparation-white material filling-black material 200KHz ultrasonic transducer filling-discharge valve-sealing-dimethyl ether filling-propane butane filling-screw cap-buckle cover-shaker is completed, it is worth noting It is for heating water or thermal oil, not heating items or stainless steel materials, in order to avoid direct contact with personnel, and comes with a liquid level display system to observe the liquid level height. Equipped with automatic distribution box to reasonably limit heat and operation.
