In furniture decoration, the main function of the junction box is to maintain the wire, but in addition to home decoration, we will use the junction box, in some factories outside the special environment also need to use some functional junction box, such as splash-proof junction box.This junction box can ensure that the screws in the box will not loosen and then open the box will not fall off.Generally speaking, when manufacturers re-consume, they will use special materials to manufacture the junction box is the PVC junction box.Splash proof junction box requires that the junction box has a very good airtight, and there is no thick flaw in the environment with water vapor, so that water vapor can enter the junction box and cause damage to the line.PVC this kind of information is very suitable.The full name of PVC is polyvinyl chloride, generally in the light or high temperature of the environment polymerization reaction occurs in the polymer.When this kind of data is manufactured, we will add some fluctuation agent to make its properties more fluctuating in the light and heat environment.By mixing the data of the current PVC junction box, the junction box can still stop the task of maintaining the line fluctuating under the condition of low temperature or high heat.
In addition to PVC used in junction boxes, some pipe and film manufacturing materials are also made of PVC.PVC junction box has longer service life, higher safety and higher function, so many consumer manufacturers will use PVC as the manufacturing materials of junction box.The way we usually check the PVC junction box is to stop extinguishing, and the fire will usually extinguish itself when we put it out.When extinguishing, its smell is generally comforting sour and there will be yellow-green smoke. This method is the most complex and indirect identification method. Generally, some solvents will be selected to stop the identification, but this identification method is not recommended to use.
