1. The styrofoam cannot be punched out
First look at the styrofoamMaterial tankwhetherhas For solidification, shake the can body with your hands. If it can be shaken, it means it is not solidified and it can be punched. If it can be shaken‘sMoving but unable to hit or unable to finish, there may betoNext question：A.glueGun assemblyNoin place,The valve is not open. Tighten the glue gun firmly and open the valve. B.The muzzle, adapter or barrel of the foam glue gun is clogged. Clean it immediately and use cleaning agent span>After cleaningCheck whether it is smooth;Or directly replace the glue gun with a new one. C.FoamglueThe valve appears “stuck”, which may be caused by being placed upside down for a long time. You can remove the can and put it aside for five minutes. Insert a nail into the valve and tap it gently with a hammer. Once you hear the ventilation sound, put the glue gun on it and you can use it. It is recommended一Used in one go. D.Due to the low temperature(5℃The following) results in the inability to type , can be placed in warm water soakIt can be used normally in about five minutes.
2. Excessive pursuitProfits, deliberately reduce costs, add fillers, and increase the weight of white materials, this kind of productNoBut the foaming volume is low and shrinkage will occur More than 50%, so a pore-opening agent was added to open the foam thenSolving the shrinkage problem,ButThat’s itThe elasticity of the foam is gone and 会Water leakage, bearing capacityis also greatly reduced. Therefore, it is recommended to use high-performance products of big brands, and not to use some low-priced off-brand products for the sake of temporary gains and leaving many hidden dangers. It is recommended to use Weigu foam glue.
5. How to solve the problem of poor adhesion during construction and the problem that the surface of the wall profile cannot be adhered to?
First ensure the bonding surface of the glue If there is no oily material or Teflon coating, make sure to clean the dust and sand on the adhesive surface or spray a small amount of water on the adhesive surface.
6. What to do if the gap is particularly large or small during construction
When encountering a large gap, such as horizontal You can first lay a layer on the bottom layer, then fill in other vertical seams, and finally fill the seams on the original basis. This can avoid oneOne-time printing Full and waste a lot of glue. When you encounter a very small gap, you can not fill it first, but use the last 100 grams or so of each can of glue to fill it.
7. What should I do if the curing is slow
Spray a small amount of water on the adhesive surface, and try to use a swinging nozzle to fill it to increase the amount of glue. When the gun is taken out, it is fully exposed to the air and shortens the curing time. If the construction period is short, you can choose pre-foamed products, which can shorten the curing time. 一general glue After punchingyou can do surface treatment after 40 minutes, and it will be completely cured and set, and it will no longer expand or shrink.
8. What should I do if the foam cells become very large after curing?
The pores of the cured foam rubber are very large, which may be due to The humidity of the local construction environment is too low. Because the foaming principle of styrofoam is to react with water to produce carbon dioxide gas and foam. This phenomenon will occur if the humidity is too low and there is insufficient water, resulting in incomplete reaction. It may also be caused by using the soaking process and pressing the bubbles too early. It is recommended to sprinkle water before construction in a dry environment, and consult the manufacturer to select the appropriate soaking time.
