Silica gel tension is insufficient, silica gel products not up to standard what reason!

Molding process there is always some bad phenomenon, silicone products in some of the more frequently used silica gel parts, to the requirement of pull a certain degree of resilience and tensile strength of the product mainly is the need to his tenacity to maintain, so in some manufacturing industry, machinery industry using silicone material once appear insufficient, rebound damping fails, all other performance of the product will be useless, so the operation of the molding process of the personnel, the modulation of the machine, the raw material of is the key to product toughness and bad. For ordinary silicone raw materials will appear some problems, such as the use of life is not up to standard, toughness is poor, lack of springback. Too much silicone oil is added in the silicone raw materials and the performance of white carbon black lead to produce chaos, silicone in silicon atoms are destroyed, sticky phenomenon in a softness to reduce, not appear softness liquidity, resulting in a decline in the tensile strength of the product after high temperature molding, product won't show up in after the completion of the production, but after a period of use in various environment will gradually appear under the conflict of product deformation, resilient rate drops, the phenomenon such as product sticky. In the manufacturer of silicone products molding process in the machine debugging cooperate has a certain impact, sometimes the staff in the process of sulfide in order to improve yield increase the production efficiency, will reduce the mold vulcanization time products will be feeble phenomenon, to increase production to reduce the time under the premise of must increase the rate of temperature reaches a certain balance, otherwise the product will appear all sorts of bad phenomenon, and the production time is too long products appear too brittle tensile tear phenomenon also occur and suggest appropriate control products in the process of production time and curing temperature. In addition to the machine in the production process, raw material, human, environment and so on a number of factors outside the toughness of the silica gel products won't appear quality problem, so the silicone products manufacturer in the production process control of the several factors, the quality of the product basic no problem!
