Maybe you are not a professional in the decoration industry and don’t know what panel glue is. But in fact, panel glue plays a very important role in our lives, especially in the process of home decoration. It is an important decoration material that is used in almost every household. Many furniture in our homes, as well as solid wood doors, etc., use this kind of glue. Panel glue is very convenient and quick to use, and the effect is very good, so it is favored by many consumers. Some professional operators also think that this glue is very easy to use. Xiaotu, let me tell you the formula of puzzle glue so that everyone can become familiar with it.
Puzzle glue formula:
Melamine: Melamine (Chemical formula: C3H6N6), commonly known as melamine and protein, IUPAC named "1,3,5-triazine" -2,4,6-Triamino" is a triazine nitrogen-containing heterocyclic organic compound, which is used as a chemical raw material. It is a white monoclinic crystal, almost odorless, slightly soluble in water (3.1g/L at room temperature), soluble in methanol, formaldehyde, acetic acid, hot ethylene glycol, glycerol, pyridine, etc., insoluble in acetone, ethers, and harmful to the body Hazardous and not to be used in food processing or food additives. However, recently, milk powder containing melamine in Qinghai, Gansu, Jilin and other provinces has exceeded the standard again, exceeding the standard by more than 500 times. It is likely that the "Sanlu problematic milk powder" that has not been completely destroyed is processed and sold.
Urea: Urea is also known as carbonamide, carbonamide, and urea. It is an organic compound composed of carbon, nitrogen, oxygen and hydrogen, also known as urea (the same as urine). Its chemical formula is CON2H4, (NH2)2CO or CN2H4O, and its international generic drug name is Carbamide. The appearance is white crystal or powder. It is a product of animal protein metabolism and is commonly used as nitrogen fertilizer for plants. Urea is synthesized in the liver and is a nitrogen-containing metabolite excreted by mammals. This metabolic process is called the urea cycle. Urea is the first organic compound obtained by artificially synthesizing inorganic substances.
Formaldehyde: Formaldehyde is a colorless gas with a strong irritating odor. Easily soluble in water, alcohol and ether. Formaldehyde is a gas at room temperature and usually appears in the form of an aqueous solution. Easily soluble in water and ethanol, a 35-40% formaldehyde aqueous solution is called formalin. There is an aldehyde group in the formaldehyde molecule that undergoes a polycondensation reaction to obtain phenolic resin (bakelite). Formaldehyde is an important organic raw material, mainly used in the plastic industry (such as phenolic resin, urea-formaldehyde plastic-electric jade), synthetic fibers (such as synthetic vinylon-polyvinyl formal), leather industry, medicine, dyes, etc.
Methanol: Methanol is flammable, and its vapor can form an explosive mixture with air. Methanol burns completely to produce carbon dioxide and water vapor, and also releases heat. Equation: CH3OH+O2→CO2+H2O? Industrial preparation method and reserve Methanol is prepared industrially using a mixture of carbon monoxide and hydrogen (synthesis gas) under certain conditions.
NaOH: Sodium hydroxide (NaOH), commonly known as caustic soda, fire soda, and caustic soda. It is also called caustic soda in Hong Kong because of its other name: caustic soda. It is a white crystal at room temperature and has Strongly corrosive. Easily soluble in water, its aqueous solution is strongly alkaline and can turn phenolphthalein red. Sodium hydroxide is a very commonly used base and one of the essential medicines in the chemistry laboratory. Its solution can be used as a washing liquid
Polyvinyl alcohol: polyvinyl alcohol, organic compound, white flake, floc or powdery solid, odorless. Soluble in water, insoluble in gasoline, kerosene, vegetable oil, benzene, toluene, dichloroethane, carbon tetrachloride, acetone, ethyl acetate, methanol, ethylene glycol, etc. Slightly soluble in dimethyl sulfoxide. Polyvinyl alcohol is an important chemical raw material used in the manufacture of polyvinyl acetal, gasoline-resistant pipes and vinylon synthetic fibers, fabric treatment agents, emulsifiers, paper coatings, adhesives, etc.
Polyvinyl acetate: Polyvinyl acetate? (Polyvinyl? acetate)
Molecular formula?: (C4H6O2)n
Structural formula: colorless viscous liquid Or colorless to slightly yellow transparent glassy particles. Odorless, tough and plastic. Will not stain or age due to sunlight and heat. It softens at about 30℃. Soluble in ethanol, propanol and benzene, insoluble in water and fat. The relative density (d4) is 1.191, the melting point is 100~250℃, the average molecular weight is 22000, and the water absorption is 2%~3% (25℃, 24h).
After Xiaotu’s detailed introduction, I believe everyone has a preliminary understanding of the formula of puzzle glue. When purchasing, you may wish to ask the opinions of professionals first, and refer to the opinions of friends who have already decorated. Xiaotu’s suggestion is to give priority to environmentally friendly materials. Don’t forget to shop around. After all, decoration is a big expense, but it also needs to be cost-effective. Of course, choosing products from big brands will be more trustworthy and have guaranteed quality, which can reduce the pollution caused by these decoration materials and make them safer to use.
