Pval glue can be used to bond paper and plastic products with a certain thickness. The main component of Pval glue is polyvinyl alcohol, which belongs to environmental protection glue and is a safe and non-toxic product. Pval adhesive also has the advantages of good bonding strength, waterproof and convenient use.
Second, what should I pay attention to when using glue?
1, there are many kinds of glues on the market. When using glue, choose the appropriate glue type according to the material of glue. For example, we can use pval glue to bond paper. If you want to bond rubber products, you can use AB glue and pvc glue. AB glue can be used to bond metals and metal materials. If you want to bond leather, ceramics and other items, you can use white latex. The adhesive strength and other properties of different glues will be different. If the wrong glue is used, it may lead to unstable adhesion of articles and so on.
When we use glue, we should first check the shelf life of the product. If the product has passed the shelf life, it is easy to have problems such as glue deterioration and unstable pasting. Try not to use glue that has passed the shelf life. If you want to use it, you can try it on a small scale to see if the product is firmly bonded and so on. In the process of construction, we should also pay attention to the construction environment temperature. Glue is best used at 23-28℃. If the temperature is too low, the glue will slowly dry. If the temperature is too high, the glue will evaporate and dry too quickly.
3. When using glue, first of all, the bonded items should be treated. For example, when bonding wood blocks, the dust on the surface of the wood blocks should be wiped clean. Can not be used immediately after gluing. We can press the glued items for a few minutes, and then use them when the glue is completely dry.
Here is a brief introduction about what materials pval glue is suitable for. Hope to provide reference and help.
