Before we introduced the influence of temperature, humidity and ventilation on sealant, so today we will introduce the influence of the last construction detail.
China joint adhesive wholesaler"s products have passed SGS, CMA and A certification. Please feel free to promote and use our products.
PS: Summary of common problems in beauty joint construction
Problem 1, Winter is difficult to glue, difficult to discharge
Reason: When the ambient temperature is below 5℃ in winter, curing agent will become sticky
Solution: Soak in 50℃-60℃ warm water for about 10 minutes (tighten the bottle mouth, discharge mouth down, bottom up, pay attention to prevent water!)
Problem 2, Blistering
a. Reason: Due to low temperature, the temperature of seam products is too high when heating, resulting in lesions of seam agent raw materials (curing agent, resin, additives).
Solution: Soak in 50℃-60℃ warm water for about 10 minutes.If it still doesn"t work, replace it with a new sealant in time.
b. Reason: The gap is damp
Solution: Before the seam, ensure that the gap is dry and dust-free. If the seam bubbles have been made, if the bubbles are not many, they can be cut and filled.If there are too many bubbles, it is recommended to dig up and clean up before the sealant is dried, and do it again after drying.
c, reason: The glue is not uniform, not enough to fill, part of the seam is too thin.
Solution: Glue is recommended to play, fill the gap without leaving a gap.
d, reason: The use of inferior products, their own bubbles more.
Solution: Qualified products generally manufacturers can adjust the formula in the production process, production technology is more mature, defoaming is no problem.If the use of inferior products caused by the need to replace the product.
Problem 3, The United States is brittle and easy to break, difficult to shovel glue.
Reasons: One is caused by low temperature, the construction temperature in winter is less than 5℃, curing is slow, the material becomes brittle;Two is higher heating, will accelerate the curing, strength rise fast, a long time inconvenient to clean;3 it is brick of hemp face, archaize does not wipe beautiful seam wax.
Treatment methods: One is to enhance the temperature of the construction site;The second is to use 50℃-60℃ warm water soak, can not be too high and mild soak too long;Three is to clean up in time in winter.
Problem 4, White after construction
Reason: In the curing process, contact with alkaline substances for a long time, indoor low temperature leads to too long curing time, or indoor humidity, moist gap, slow curing and easy moisture absorption, will lead to white joints after construction.
Treatment: Clean the gap, ensure no moisture and no water drop, the gap to keep dry.Once there is a whitening phenomenon, it is recommended to shovel off the whitening place and do it again.
Problem 5, Not solid
Reasons: First, the gap is wet;The second is that the construction did not knock off the glue in front of thirty or forty centimeters, resulting in uneven mixing;Third, there are problems with the glue gun, resulting in uneven rubber out of AB material, rubber channeling, and uneven mixing.
Treatment methods: One is to ensure that the gap dry dust-free;Two is must press the correct construction method construction;Third, it is recommended to use the glue gun with uniform force and good quality, or check the glue gun and tighten the screws before the glue gun is stitched.
Problem 6, Gap edge residual material cleaning is not clean
Cause: There are problems with the glue gun. The screws on the push plug and push rod of the glue gun are loose, leading to uneven glue release and rubber shifting of AB material, so that the mixing is not completely uniform.
Solution: It is recommended to check the glue gun and tighten the screws before sewing.The use of uniform force and good quality glue gun.
