The service life of the polyurethane foam filler after curing isHow long will it be used? It appeared in a few yearsAgingorDeformation‘sQuestion? The editor of Weigu will explain it to everyone.
The main ingredients of styrofoamGeneralis polyurethane, which has veryStrong stability, The foaming principle of the foam caulking agent is that after it is sprayed out, it will mix with the air. The moisture in the product undergoes a curing reaction to solidify it. High-quality foam glueAfter the reaction is completedHard quality, strong adhesion. Use foam glue before curingSpecialCleaning agent canvalidClear,High quality‘s foam rubber does not need to worry about the life of the foam rubber‘sQuestion.
However, the following situations can cause problems with the foam glue after the wooden door is installed:
1、In order to save costs, the installation master or manufacturer reduced the amount of foam glue used on each door cover. Theoretically speaking, all positions are filled and no gaps are visible, which is the most perfect effect. Taking a step back and adding five dots from top to bottom and three dots at the top can also ensure strength. Any less and the effect will be much weaker.
2 In order to be quick, the installation master started to install the door leaf before the foam glue was completely cured, resulting in deformation or weak bonding.
3 , the manufacturer’s door cover material itself is not strong enough, and the quality of the door itself is too poor, no matter how good it isFoam glueIt’s impossible to stick to it.
4 . There are problems with the walls of the openings of the house, such as the walls cracking and falling off due to moisture, etc.
5. The styrofoam provided by the manufacturer itself is an inferior product. After it is sprayed out from the tank, the reaction speedverySlow, low hardness and weak adhesion ,The foaming effect is very poor and affects the adhesion. >
So if you use high-quality styrofoam products, if the above 5are not included, it is almost impossible to have problems with the styrofoam >.
