Anonymous users2024-01-23Under normal circumstances, solid wood furniture does not use 502 glue. Because 502 glue is based on ethyl cyanoacrylate, adding tackifiers, stabilizers, toughening agents, polymerization inhibitors, etc., and the one-component synthesized through advanced production technology is instantly cured and sticky, which can stick many things. 502 glue has a certain toxicity, but the toxicity will be reduced after curing, but 502 glue is a cyano compound after all, and it will produce toxic substances after decomposition.
In case of moisture, it is catalyzed, and it is quickly polymerized, solidified and adhered to it. The polyaddition reaction occurs under the catalysis of trace water in the air, which cures quickly and sticks to the sticky.
502 glue is used for porous and absorbent materials, and is used for steel, non-ferrous metals, rubber, leather, plastics, ceramics, wood, non-ferrous metals, non-metallic ceramics, glass and flexible materials such as rubber products, leather shoes, soft and hard plastics, etc. It is widely used in electrical appliances, instruments, machinery, electronics, optical instruments, medical, light industry and civil industries.
Adhesives used in the furniture industry generally refer to wood adhesives, which are materials that bond wood to the surface of wood or other objects. According to the different sources of raw materials, furniture adhesives can be divided into two categories: natural polymer adhesives and synthetic polymer adhesives. The adhesives widely used in the furniture industry belong to synthetic polymer adhesives, among which the most widely used and the most representative is acrylic AB glue, including urea-formaldehyde resin glue, phenolic resin glue and melamine formaldehyde resin glue.
In addition to formaldehyde-based solvent-based adhesives, the most widely used adhesives in the furniture industry include other water-based adhesives and synthetic rubber solvent-based adhesives, such as polyvinyl acetate emulsions, acrylic emulsions, polyurethane, neoprene, etc.

Lacquering solid wood furniture can not only ensure that some of the properties and characteristics of solid wood materials are effectively retained, but also improve its ornamental value in terms of texture, and at the same time avoid wood chips on the furniture from scratching consumers' hands, so as to protect the health of consumers. >>>More
Good mahogany furniture is not painted, but painted because there is a large difference in the color of the wood itself.
Specific methods to remove 502 glue from furniture:
1. In the place where there is 502 glue, drip China Resources high-efficiency glue remover, this process is very important, you need to let the liquid stay on the surface of the glue, otherwise there is no way to soften it. If it is a façade, you can first drop it on a cotton swab or paper towel and then apply it to it. In this way, the liquid will not flow around. >>>More
Generally not painted, if the lacquered ones are basically fake, there are many kinds of ebony, the main distinction is which kind of origin is where, the method of identifying the true and false, the most common method of ebony counterfeiting is to use the Mozambique skin ash wood to paint and paint, and the authentic Indonesian ebony due to its characteristics, the utensils made are generally not lacquered, the production method is mainly polished, the polished utensils are full of luster, with the use of time for a long time, The oil secreted by the utensils itself will gradually form a transparent protective layer on the surface, we call it slurry, the fuller and thicker the slurry, the higher its value, and the brothers who watch the CCTV treasure column must know! Therefore, the identification method is very simple, you should be careful when you see lacquered objects, and if you can, use coarse sand to grind off a layer. Due to the huge profits of counterfeiting, inducing some unscrupulous merchants to ignore the interests of the majority of burners, and continue to use defective fakes into the market.
