2020-03-09(1) The additives in the rubber compound are not uniformly dispersed during mixing. (2) There are many impurities in the vulcanizing agent, impurities of small molecules become decomposed......
2020-03-09At present, most of the main bodies of high-rise or super high-rise buildings are made of steel, which has poor fire resistance performance. If effective fire protection measures are not taken, the st......
2020-03-07In the petrochemical industry, the chemical industry and the metallurgical industry, pipes, furnaces and other thermal equipment are common. Using SiO2 aerogel and its composites to replace traditiona......
2020-03-07Non-supercritical drying technologies include atmospheric drying, subcritical drying, and freeze drying. Subcritical drying is similar to supercritical drying, except that the temperature and pressure......
2020-03-07When the organic solvent or water in the alcohol gel is heated and pressurized above the critical temperature and pressure, the gas-liquid interface in the system will disappear, and the capillary pre......
2020-03-07At present, the preparation of SiO2 aerogel generally adopts the two-step method of first acid and then alkali. A low pH value is conducive to the hydrolysis of TEOS, and a high pH value is conducive ......
2020-03-07Increasing temperature is conducive to the collision and coagulation of sol particles, which is considered to be inversely proportional to the gel time. However, excessive temperature is likely to cau......
2020-03-07As 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......
