Sometimes silicone parts appear cracks, aging, deformation and other undesirable phenomena, which eventually cause the product to show no use value. For some electronic parts, mechanical and electronic miscellaneous parts, this phenomenon is the most common, so for silicone parts The bad phenomena of accessories can be prevented and controllable. For the premise of silicone products, the first thing to do in terms of the power of pre-control accessories is the following!
For the cracking phenomenon, it can prevent and control the hardness, softness and right angle of the product, improve the tear strength and tensile strength from the raw material, and increase the inclination on the mold of the product to maintain the R angle to prevent the phenomenon of tearing and pulling. , The vulcanization time remains stable during processing. If the time is too long, the probability of tearing of the product will be more likely to occur. The cracking phenomenon can be controlled by these methods in the silicone product manufacturer, and the use process must be controlled by the strength of the use!
Aging phenomenon, a phenomenon that occurs in every product with an aging rate, and the silicone material accessories are also the same, so for the aging of silicone accessories, one of the first is to find the problem on the raw materials, because the performance of silicone is different. The environment and conditions used are also different. The second is the reaction of the environment and conditions. After research, it has been shown that the aging phenomenon of silicone rubber products can mainly be caused by oxidation, heat, stress, and liquid effects in the environment and area of use. The phenomenon of accelerated aging of products, oxygen in ozone The damage performance is relatively large in the middle, and the molecular chain compounds of the silica gel are different, which leads to the change or decrease of the performance of the silicone rubber products. The heat effect, the silica gel can withstand high temperature, but the use of the polymer activator under high temperature for a long time will cause the active polymer activator to cause the expansion of the silicon atom, which will soften and become soft. Bubble and other phenomena, so for the aging phenomenon, it mainly depends on the environment and conditions you use!
