Hello everyone, I am Xiaolei. Today I will talk to you about whether the door set installed withfoam filler will loosen after a long time. Many friends are also struggling with this point. Many friends are worried about the door set installed in their home. The installation master uses foam filler to install it, so after a long time, they will worry about the quality of the door, so today Let me talk to you in detail.
The first is foam filler, which has been widely used since the advent of door sets. At first, foam filler was used alone The polyurethane foaming agent is mainly used for sealing and filling. It has not been widely used for installation and fixation. However, with the increasing number of packaged doors, foam fillers are now indispensable for packaged doors. .
Foam filler is a process in which after it is punched out, it reacts with the moisture in the air and the moisture in the matrix, and then expands and then solidifies. Then this material has a negative impact on the ambient temperature of use. There are relatively high requirements, that is to say, they are lower than Below five degrees, or above 35 degrees, it will also produce some adverse factors for the curing of the foaming agent. Generally speaking, it is a relatively low temperature, or a relatively high temperature, for the curing and curing of the foam filler. Its use and how strong it is will also have a big impact.
After this material is filled, bonded and puffed, it will gradually reach an optimal hardness, which means that The strongest adhesion state, then as the use time increases, this material will oxidize with the air, which means it will gradually lose its toughness, and it is not resistant to ultraviolet rays, so it is recommended to use foam filler for installation After the suit door has been used for a long time, it will definitely become loose.
We also have certain solutions to looseness, because when the set door is initially installed and used, the manufacturer of the set door will be equipped with A special fixing piece for the set door is then nailed into the wall, and then foam filler is used to assist the bonding. With the reduction in configuration, the current set door no longer has the previous fixing piece to match, so we I can only think of some ways to solve the problem of loosening of the foaming agent after a long time.
First of all, the foaming agent reacts with the moisture in the air and the moisture in the matrix , that is to say, when it is drier and the wall is drier, its bonding strength will definitely not be high, so we need to pour some water on the wall before installing the set door, so as to ensure foaming agent to achieve an optimal adhesive strength.
The second point is that the larger the sticking area of the foaming agent, the higher its sticking strength, so when we are installing When making dots on the suit door, the dots should be slightly larger so that the adhesive strength can be increased to a relatively high level.
The third point is a problem of the ambient temperature of use, because the best sticking strength of the foaming agent is above five degrees and below 35 degrees, so the foaming within the temperature range The agent can reach a certain strength. If the temperature is relatively low in winter and we need to install a set door in our home, we can only choose to use an electric heater to adjust the ambient temperature. degree of heating, or wait until the weather warms up before installing the door set. Furthermore, when the ambient temperature of the foaming agent is relatively high, its cell structure will become worse and worse, which will also affect its adhesion. Bonding strength, when the temperature is too low, and the activity of the foaming agent is relatively low, powdering will easily occur, and the bonding force will also become worse and worse, so we should not use it outside the ambient temperature. Went to try installing the kit door.
The last point is that during the use of the foaming agent, it swells first and then shrinks.In the process of shrinking, to prevent the door gap from getting wider and wider, we need to install a few wooden wedges at the hinge position of the door gap, so as to ensure that after many years of use, this set door The gaps are still in the original state of installation.
Okay, today\’s article will be shared here. I hope it will be helpful to everyone. See you in the next issue.
