White latex glue is a commonly used water-based glue for wood processing. How to judge the quality is particularly important, because whether it is used by manufacturers or home decoration, if white latex glue of poor quality is used, it will contain a large amount of formaldehyde, toluene, etc. Hazardous substances and the use of such glue will not only endanger the health of furniture manufacturers and buyers but also affect the bonding strength of the product.
Therefore, it is extremely important to use simple methods to judge the quality of white latex glue. Below, I will share with you some simple methods to judge:
1. Judge based on smell
If it is white latex glue produced by a regular woodworking glue manufacturer, you can open the lid of the packaging barrel and smell it first. Good glue will have a light latex smell, while poor glue will have a spicy and pungent smell.
2. Judge based on touch
Good white latex glue can be touched gently with your fingers. It will feel smooth and delicate without any obvious graininess. Use a wooden stick to stir the glue, and then use the stick to gently lift it. Good white latex glue will form a fan shape. Moreover, after the glue is left in the air for a certain period, a layer of elastic oxide film will be formed on the surface of good white latex glue, which is not easy to crack. On the contrary, the film of bad glue will be very thin and will crack at the slightest touch.
3. Judge based on solid content
The solid content refers to the ratio of the remaining solid content of a certain weight of glue liquid after the volatile substances are volatilized at high temperatures. The solid content is directly proportional to the time required for the glue to cure. The higher the solid content, the faster the curing and the faster the initial strength. For glues produced using the same product process, good white latex glue has a higher solid content and a shorter drying time than poorer ones.
4. Judge based on the effect of broken materials
To put it simply, the material-breaking effect refers to the damage to the base material after the base material is bonded with glue. For bonded wood, it is the wood breakage rate of the product and whether there is degumming. The base material of a good white latex glue bonding surface has a large damage area and will not be degummed. This kind of white latex glue is better.
The above 4 methods can allow everyone to easily judge the quality of white latex glue. I hope it will help you choose white latex glue.
