Glue is easy to use, resistant to storage, simple to make, large or small in scale, and does not need to waste food. Glue is used to bond objects, because it is liquid, so it is easier to apply paste than solid paste, and the adhesion is not so strong. For a large number of places that need to be pasted, glue is better. Glue used to be packed in a paste-like straight bottle with a dip pen attached. But because glue is liquid, it flows out easily when it is reversed. In order to gradually put it into a long conical plastic or glass bottle for your own use, the bottle mouth is wrapped with a glue stick, which is also very convenient to use.

Formula 1: Take 4.5 parts of Arabic gum, soak it in 100 parts of water for 24 hours, then heat it in water bath until it is completely melted, then add 1 part of liquid carbolic acid, stir it evenly, filter it with cloth, cool it and bottle it for sale. Its sales can be distributed by contacting local department stores or stationery stores. Gum Arabic used in the formula is a kind of gum oozing from the trunk of rubber tree and other plants in Leguminosae. Colorless or yellowish translucent granular or fragmented, odorless, light and sticky, extremely brittle on the ground and slightly shiny on the surface. If ground into powder, it is pure white and extremely sticky. The main component is gum Arabic, which is essentially salt, such as calcium and potassium of gum Arabic, as well as oxidase, peroxidase, tannin and so on. Its function is to use its viscosity to make various adhesives. The glue produced by this formula is specially used to bond paper. If paper and metal need to be bonded, strong water must be used.

Formula 2: 3 parts of gum, 30 parts of gasoline and 0/part of mastic fake paint. The production method is to cut the gum into small pieces, put it in a big glass bottle with a stopper, add gasoline and shake it constantly to dissolve the gum, and then add frankincense fake paint and mix well. If it is too thin after cooking, you can put it in a pot and heat it slightly to let the gasoline volatilize a little (be careful not to get close to the fire). If it is too strong, you can add a proper amount of gasoline.

Formula 3: gum Arabic 180, water 550, glycerin 60, carbolic acid 1. First, add 50 parts of water to glycerol for dilution, soak Arabic gum in the remaining water for 65,438+0 days, then pour it into aluminum pot and heat it in another kettle. Add viscosity at the temperature of 60-765,438+/-0 degrees, and keep stirring until the rubber particles are completely melted and the thickness is uniform, then pick up the aluminum pot to stop heating, add diluted glycerol and carbolic acid, and then apply force.
