There are consumers who buy silicone products and find that there is a phenomenon of breakage on the edge, which often troubles many friends and leads to a certain cognitive requirements for silicone products, less a certain purchase rate, and for silicone products edge damage phenomenon is not helpless. Silicone products edge damage in the silicone products industry is called "edge explosion" the main reasons are caused by several phenomena, the product in the process of use due to the serious force and the impact of the mold caused dislocation phenomenon, so that the silicone products have minor damage resulting in subsequent gradually wear. Secondly, the product itself is damaged, in the production and processing of silicone manufacturers due to the temperature and material fixed-line problems caused by product damage phenomenon, in addition to the hardness and curvature of the product shape also has a certain impact, so the product damage problem can be controlled in various aspects of the cause!   1, hardness problem, low hardness silicone products bursting edge is more common, the main phenomenon of low hardness is the parameter deployment of silicone products manufacturers, such as the temperature of the machine and secondary exhaust problems, so set the parameters of the machine is very important, the temperature is reduced, the vulcanization time is reduced, the molding processing time of the product is just controlled in the stage of curing completion. If the time is too long, there will be material expansion of the raw material in the machine, resulting in the separation of the parting position leading to rupture.   2, raw materials are the key to silicone products, if the raw materials in the production process is not mixed in accordance with a certain time or the added part of the additives are insufficient, it may lead to various problems in the production process of the product, such as edge explosion, poor fluidity, product bulge and deformation.   3, the structure is more complex, the product explosion damage phenomenon is also relatively large, in addition to hardness, usually silica gel products explosion phenomenon in the case of low hardness with the product structure has a great relationship, such as the product is relatively thick, there is a certain arc and parting position at the high point of the product, so in the product design at the same time need to strictly control its parting position.   4, the mold is the key to the edge damage of silicone rubber products, in the mold development at the same time, how to butt inconsistent with the upper and lower parting point dislocation phenomenon, then production The problem of product damage has not been solved, so the mold processing needs to be strictly controlled.   5. Other reasons Some exceptional factors can also cause the product to explode, such as: The weight of the rubber material is not well controlled (too heavy will cause the product to explode, too light will cause the product to lack of material, lack of corners, so control in a reasonable weight will reduce the probability of explosion) Secondly, in the long-term production process without intermittent conditions should be reduced mold temperature, Keep the mold in a certain temperature range, etc. (Spray the mold with water to maintain the temperature of the mold properly without intermittently).

Aging life is the hard wound of the silicone ring, all suitable for the sealing benefits of silicone products have such a disadvantage, such as our common machine doors and Windows, electrical product sealing and car waterproof sealing ring in the middle of the city found the inevitable shortcomings, regardless of the choice of silicone or rubber and other materials through the situation and the training of time are gradually lost efficacy can not reach the reality Fruit, showing the benefits of not producing things. There are many important reasons that affect the application life, but the silicone ring will be affected by several common signs in the service seal. Affected by the strength of the roughly shrinkable permanence, According to the different method of placement, plane, rugged groove or groove, etc., the difference in the placement method of each product is very likely to cause the uneven force to find the force center shift, and the discovery side is heavy The edge light causes shrinkage permanent deformation through the permanent accumulation force, and when the sealing silicone ring is removed again, it is very likely that the shape situation has been found, so the average and the level of the force need to be mastered at the same time. The product size is wrong resulting in fracture deformation The gap question can be divided into several components, first, because of the material of the rubber material question, very many silica gel material because of the formula found poor resilience, tensile force is not enough to cause the problem in the application process is not strong enough to find cracks caused by leakage, Silica gel ring and manufacturers processing questions: for example, the product is brittle resulting in the relatively thin thickness of the silica gel product, it is easy to find this question, and the product is soft causing the rubber material to have an internal bulge, and the deformation of the cracks is found after stretching and compression forever. The product is soft or brittle resulting in ineffective effect, very often not the layout of the material and the product, but in the middle of the silicone rubber product manufacturer manufacturing process caused by the product character specifications are affected, such as the hardness and softness of the final product when processing, the processing time is extended resulting in the product is too brittle in the process of installation found cracking signs, and probably want to be promoted The product is found to be soft, resulting in deformation signs when the product is stressed. Hard and soft influence, very often based on the difference in the softness of silicone rubber products can completely change the efficacy and layout of the product, so the silicone sealing ring in the application process because of the selection of different hard and soft in the force, Tensile, extrusion and other signs are found, the sealing ring will find a few unavoidable questions, such as extrusion cracks, excessive strength, high hardness, product deformation without rebound and so on.
