What are the ways to maintain the sand table model

The sand table model is too big to install a glass cover, then the unshrouded sand table model needs to be cleaned. There is also sound, light, electricity, the circuit at the bottom of the model needs to be repaired, and how to open the entrances and exits for maintenance personnel is also a problem. Some sand table model in addition to consider the division, transportation, entrances and exits and other factors, but also to consider the sand table at the bottom of the electrical insulation, heat, fire and fire prevention and other factors. In addition, due to various materials thermal expansion and contraction coefficient is not the same, so to avoid sand table model placed on the site space temperature difference is too large, and to avoid direct sunlight, all of this in the specific production of a set of mature practices, but it is important to take these factors into account.

In addition to the working sand table model, the general use of the model has a certain preservation value. If the preservation period is very short, you can use paper, cloth, plastic sheeting, etc. to cover the model to prevent dust; if the preservation period is a little long, available cardboard, plastic sheeting, etc. to make a dust cover; if the preservation period is very long, the available 2 ~ 5mm thick plate glass glued into a dust cover, because of the good transparency of the plate glass, high strength, can withstand the many times to wipe the dust of the friction, and also to prevent people touching and moving the model, and more able to readily Viewing.

Whether the sand table model is saved separately or centrally, we should pay attention to moisture, sun, high temperature, because no matter what material model by moisture, sun or high temperature, may produce deformation and discoloration, which is extremely unfavorable to long-term preservation. Try to use a large red velvet sand table model and glass cover with a cover, plus a layer of plastic sheeting, so that both dust and sunscreen, but also to improve the sand table model of its own value. Sand table model design finished products should be stored in a special room, special custodian, in order to give full play to its function. Model storage room requires smooth ventilation, bright and clean, should avoid direct sunlight model.
