Application of various glues
There are many types of glue, and various glues have different applications. To glue larger xylophone parts and adhesive walls, glue or latex can be used. Water glue should be used hot. When the glue is used, put the dry glue in the iron pile first, add water, and then put the iron rake in a container filled with water (boil the gluer) and heat it strangely. In this way, the glue will not be traced back, nor will it shape the drillability of the glue. When the mold is wet, apply hot glue, and then use a clip to clamp it tightly to make it tight with a string. Keep the glue in place until it hardens. The glued parts can also be reinforced with small nails, which should be nailed where the subsequently installed component can shave the nail.
Adhesive surplus water glue, should not be immediately dry brush with a good glue. Latex does not have to be heated. Before use, put the glue into cold water, and how much it should be used, it should not be left until the next use. The glue dissolves in about 20 minutes, and its concentration should be similar to that of the upper layer of thick sour milk. Its use is the same with water glue. Latex should be placed in a sealed crucible and gradually lose its viscosity in the air. Superstructures, equipment components, and permeable screeds made of thin metal wire should be coated with synthetic rubber on the surface of the piano before painting. After that, the parts can be fixed in place.
This glue can be replaced by a colorless nitrocellulose roller. When used, place a small amount of nitrocellulose varnish on the lid of the person's metal. When it is thick, use it like a water gel. Careful attention should be paid when pasting small pieces of various colors. If the glue is sluiced from underneath the parts, the varnish and the oil coating are dissolved to form spots or leaks, then all the labor may be lost. When the paper is dried, the glue is used to make a similar glue.
