With the continuous development of film and television industry, in order to achieve more realistic effect, many scenes are all made of silicone material to replace, for example, we often see cremate bodies in the scene, if special effects post-production so effect is not so realistic, if made of silica gel to replace the dummy effect will be more realistic.So many in the choice of silicone film and television props need to pay attention to what?
First of all, the choice of materials is particularly important. The wrong choice of materials will affect many problems in the later period.A simple example is the silicone dummy mentioned above. If the fluidity of the material is not good, the silicone dummy will have a lot of bubbles, and there will be a lot of uneven pores on the face of the dummy, so that the products made will have a lot of defects and not enough lifelike.If the selected material has poor tearing performance, the silicone dummy made will not be durable, such as easy to fracture or damage in handling or storage;Z is the most important thing is that the silica gel with bad material is easy to produce oil, so the color of the later painting will have a great influence, leading to the production of the silica gel dummy is not realistic enough.So how to choose the right silica gel material for yourself?First of all, choose well-known brands at home and abroad, such as dow Corning, Japan's Shin-yue, Germany's WACO, and China's Hongtu silica gel, which are well-known liquid silica gel brands at home and abroad, the quality of the production of silica gel is more guaranteed;In addition to the selection of well-known brands, we also need to do a skin test in the process of use, such as the production of some silica gel curing sheet to test the physical properties of silica gel (tear strength, tensile strength, elongation, shrinkage, hardness and other physical properties) to understand whether the performance of the product can meet the production product needs;Secondly, a good sample can be simply painted to see how the coloring effect of the product is, whether it will fade, etc. If these tests can meet the basic requirements, then the material is not a big problem.
Secondly we must pay attention to the details in the use of the product, the ratio of different types of silica gel with curing condition is different, used to make the film and television props silicone usually has two kinds, one kind is industrial-grade silicone is a 100-2 ratio of silica gel, the other is a kind of food grade silicone surface does not have any taste ratio is the ratio of 1:1, The base material produced by these two kinds of silica gel is not the same, especially food-grade silica gel can not contact with industrial grade silica gel, including the use of industrial grade silica gel mixer container contact, otherwise it will lead to the non-curing of silica gel.As for the choice of these two kinds of silica gel, you can choose according to different needs.
In addition to the above matters needing attention, there are many other things, there may be no way to list them one by one. If you want to know more information about silica gel, you can consult hongtu silica gel professional team to answer them.In fact, film and television props are not only the production of silicone dummies, there are many aspects can be produced such as human prosthetics, head, facial features, viscera and so on.
