After the mixing of the silicone rubber compound, the parking time should not be less than 24h, so that various compounding agents (especially structure control agents) can fully function with the raw......
2019-12-16Too much plasticizer or structure control agent is added to the rubber compound, resulting in poor rubber resilience and slow vulcanization speed; too much plasticizer or structure control agent is ad......
2019-12-16It is also an important factor that leads to poor rubber resilience and slow vulcanization speed. As the white carbon black itself is acidic, and the added structure control agents are mostly acidic, ......
2019-12-16The rubber does not reach the normal sulfur point during vulcanization, the vulcanization speed is too long, and the vulcanization is insufficient, resulting in poor rubber elasticity. You can solve t......
2019-12-16The sealant is formed into a strip from a plastic bottle, and the following properties can be tested or simply judged during the process of applying the glue and observing the strip. (1) Squeezabil......
2019-12-13(7) Squeezability: This is an item of sealant construction performance. It is used to indicate the ease of use of the sealant. Too thick glue is poor in extrusion properties, and it is very laborious ......
2019-12-13(4) Elongation: Elongation is the elastic performance of the sealant after it is completely cured. It also belongs to one of the mechanical properties. It refers to the percentage of the total elongat......
2019-12-13(1) Appearance: The appearance of the sealant mainly depends on the dispersion of the filler in the base rubber. The filler is a solid powder. After being dispersed by the kneader, mill, and planetary......
2019-12-13Environmental factors have a significant effect on the curing properties of sealants. The first is the effect of temperature. The higher the temperature, the faster the curing reaction speed. The phen......
2019-12-13The one-component sealant sealed package is stable in the container, and it will solidify when it is exposed from the container when exposed to the air. This is a chemical reaction process. The sealan......
2019-12-12Organic silicon construction sealant is mainly composed of base glue, filler, cross-linking agent, catalyst and other additives. Base glue is the basic material of the sealant, which determines the pe......
2019-12-12Silicone building sealants are condensed through chemical reactions to cure volatile small molecules. This type of product can be classified according to the different chemical reactions, that is, the......
2019-12-12Building sealants can be classified according to different methods, such as the structural sealants and non-structural sealants mentioned above. This is a classification method, which is based on the ......
2019-12-12Construction sealant is a paste-like construction sealing material composed of basic rubber, fillers, curing agents and other additives. After being used, it will cure to become a flexible rubber mate......
2019-12-12Peroxide vulcanization refers to organic peroxides that release free radicals when vulcanization and heating are added to the rubber ingredients (such as peroxide propylene and so on). Peroxide ur cau......
