Liquid silica gel products have its defects in strong things, silicone rubber material is no exception, we use countless silica gel seals in daily necessities, in sealed and dustproof daily necessities, decorative gifts and electronic products, for performance it has good advantages, but also has a fragile side, Today we will explain what rare defects silicone sealing products have in the use of the problem!
Alkali corrosion is impact on any material, the silica gel from tensile tearing resistance and rebound has certain advantages, solvent solution is the only thing this material can be in harmony for soft matter, after experiments showed the silicone material come into contact with acid solution such as (sulfuric acid, hydrochloric acid), silicone material will be reduced to software matter such as silt shape, after long-term abuse bubble will gradually concentrated burn, It doesn't go away completely!
Silicone material belongs to the highly active small molecules, adsorption material itself has been with the adsorption dynamics, so make the silicone product will naturally, the phenomenon of the adsorption stained with dust, it is a common phenomenon, so sometimes you in industrial use to seal looks bright surface covered with dust impurities in raw material is the main reason, Secondly, the die surface on the die is too smooth, resulting in the phenomenon of greater adhesion!
When a seal glue a degree of stress is beyond the product itself after the limit will naturally cause certain deformation effects, the silica gel products stress deformation phenomenon is rare, so the long-term stress after the extrusion and vibration will certainly lead to products in the internal molecular chain rupture, deformation of products won't play leads to aging, gradually appear failure phenomenon of performance!
Bubbling phenomenon, liquid silica gel products bubbling problem more than one or two consumers reflect, then what is the specific reason for the emergence of oil?
Point adhesion phenomenon occurring to the touch feeling sticky, there are several main factors, first is raw materials mixing when adding dose of silicone oil and other compounds, prompted a residue after synthetic material after high temperature vulcanization molding products will slowly ooze oil in a certain period of time, the other is caused by silicone rubber products factory production, Such as vulcanizing agent and the addition of internal demoulding agent and surface demoulding agent spraying lead to facial compound residue intervention, after long-term use slowly began to appear oil!
