What causes deformation of silica gel products forever

by:TaiHai     2020-07-23

in the silicone products factory production test, performance test of semi-finished products is particularly important, so let us have a science the deflection of the silica gel products.

why silicone deformation

in the silicone products belong to synthetic rubber silicone rubber material, its physical I mainly belongs to a kind of viscoelastic stronger solid silica gel, also is not to say that the silicone permanent will not deformation, if deformation occurs on braced for a long time do not rebound, his main deformation is determined by material hardness of the silicone rubber products, the more soft material deformation, the smaller the o-rings deformation resilience of industrial equipment can is very important, stretching rate for a sealing ring is quite important.

if the loss of tensile rate and deformation situation should be timely replacement, in order to avoid unnecessary happens, and affect the deflection of the silica gel products main has the following several ways.

1, the long-term work lead to permanent deformation, use for a long time under the condition of high pressure, under the condition of high pressure for material hard products better easy to deformation.

2, the influence of tensile rate, the product of hard softness to decide, general silicone rubber of the highest winning percentage can reach 300% to 600% ( Soft material) , but in the use process of overstretch will directly lead to deformation and loss of permanent deformation of tensile strength, so you should don't overdo it stretched in the using process, regardless of industrial products, supplies or silicone accessories are the same.

3, temperature influence, a wet place, when the work of silicone rubber products, under the condition of damp heat in use process, stretching, gradually will be out of shape, but as the temperature of the adaptation and fall can also lead to slight deformation of silica gel products. So whether it's on the industrial application of accessories, sealing products, in addition to the tensile thought try not to let the silicone products.
