Make a chemical model, how to make your own chemical model

Gypsum, gypsum ** economical, easy to use and process, used in ceramics, plastics, model making, etc. The gypsum has a delicate texture, is easy to repair the surface decoration processing after molding, is easy to store for a long time, is suitable for making models with various requirements, and is convenient for display. Metal, steel materials are used in many applications, such as various specifications of steel, pipes, plates, and sometimes a small amount of other metal materials such as aluminum alloys.

The production of metal model materials mainly considers factors such as mechanical properties and cost. The mechanical properties are mainly considered from the strength, elasticity, hardness, stiffness and impact tensile ability of metal materials. The metal model processing process mainly includes cutting, welding, casting, forging, etc.

Due to the limited processing conditions in the laboratory, there are few options for metal model processes. Oil sludge, oil sludge is a kind of...

Chemical models are generally made of molecular models, and they are generally done using some waste materials. Of course, there are also specialized chemical models. You can buy it directly.

If you don't want to buy it, you can make your own with plasticine and black short sticks.

Atoms are represented by spheres and covalent bonds are represented by short rods.

Hydrogen is blue, the smallest, carbon is black, 2 to 3 times the diameter of hydrogen, oxygen is one unit of hydrogen larger than carbon, red is used, so that most of the organic matter is fine, and if necessary, nitrogen is purple, the size is between carbon and oxygen. Phosphorus is green, which is larger than all of the above, and then there is sulfur, which is slightly larger in size than phosphorus.

With table tennis and bamboo sticks! The easiest and most economical

Materials: Waste table tennis balls, plastic shells of Chinese medicine pills, plastic balls for toys, iron wire with a diameter of 3mm, a mixed solution of acetone and ethyl acetate (1:1).

Generally, you can first make a ball and stick model of inorganic molecular structure, then a scale model, then a crystal structure model, and finally a ball and stick model and a scale model of organic compound molecules. According to the atomic radius and bond length data listed in the textbook and the uniform ratio of the actual material, the bond length can be enlarged when making diamond and graphite crystal models with table tennis balls. In order to facilitate the production of the model scale is unified, the appearance is neat and standardized.

How to do it: first cut the cracked ping ball (or plastic pill shell) and dissolve it in a mixed solution of acetone and ethyl acetate (1:i) to form a paste and bottle it as a binder.

When making a model of a ball and a bat, atomic crystal, and ion crystal model, you can thread a red hot wire into a table tennis ball, and then dot a drop of adhesive at the node; When making a scale model, it is necessary to use plastic balls of different sizes, cut into hemispherical shapes with red-hot iron wire, and then glue them with adhesive; When making a tightly packed model of metal crystals, you can bond them layer by layer, and then layer by layer. The order and diagram of the atoms in the various models are presented in the textbook. Finally, it can also be painted and colored as needed.

I don't know if it's a chemical model.
