As early as 1931, Steven.S. Kistler began to study aerogels. His original method was to use acidic concentration of sodium silicate aqueous solution, redissolve silica with supercritical water,......
2020-03-06Aerogel generally refers to a lightweight nano-solid material with nanometer-sized ultrafine particles aggregated to form a nanoporous network structure, and the pores of the network are filled with a......
2020-03-06White carbon black has a very significant reinforcing effect on various rubbers, among which the reinforcing effect on silicone rubber is particularly outstanding. ......
2020-03-06There are a large number of micropores on the surface of the white carbon particles, which have a strong adsorption effect on the vulcanization accelerator, so the vulcaniza......
2020-03-06The ability of white carbon black to form gels is comparable to carbon black. Therefore, when mixing white carbon black, the Mooney viscosity of the rubber compound increase......
2020-03-06White carbon black, especially gas phase white carbon black, is the best reinforcing agent for silicone rubber, but there is a problem that hardens the compound rubber, which is g......
2020-03-05Due to the large specific surface area of white carbon black, it tends to secondary aggregation, and it is very easy to absorb water in the air, resulting in strong hydrogen bond ......
2020-03-05The surface of white carbon black has a strong chemisorption activity, which is related to the surface hydroxyl group. It can be combined with water in the form of hydrogen ......
2020-03-051. The use of modified silicone oil: on the one hand, it can inhibit the yellowing of the silicone rubber after vulcanization in the second stage; on the other hand, it can increase the vulcanization ......
2020-03-05For high-temperature vulcanized silicone rubber, two-stage vulcanization is usually required to remove the decomposition residues of the peroxide, while further crosslinking the silicone rubber to obt......
2020-03-05Mixing is one of the most important components in the rubber processing process. Mixing can be performed by separate mixers and mixers. The mixer mixing is also divided into high temperature and low t......
2020-03-04A product obtained without strict technological processes, even if the inferiority of the product can not be detected on the spot, it will always be built on a quicksand like a pagoda, I wonder if it ......
2020-03-04As a rubber product manufacturer, there are often questions: rubber formula, technology and other technologies are definitely important, but how important is it, how much gold does he have, and can a ......
2020-03-04If there are large particles or large rubber in the sealant, it is a control problem in the production process, which can be solved by strengthening management and strengthening control. If there a......
2020-03-04The surface drying time of the weather-resistant rubber is 30-40 minutes, which is not short for normal construction, but the surface drying will be faster when the construction environment changes gr......
