Abstract: Provided is an aerogel blanket and a method for producing the same, wherein a catalyzed sol is sufficiently and uniformly impregnated into a blanket in an impregnation tank, and the catalyzed sol is allowed to stay in the impregnation tank for a specific time to control fluidity while achieving a viscosity at which the catalyzed sol can be easily introduced into the blanket, thereby forming a uniform aerogel in the blanket. As a result, the uniformity of pore structure and thermal insulation performance of an aerogel blanket are improved, the loss of raw materials is reduced through the impregnation process, the occurrence of process problems is reduced, and the generation of dust is reduced.

Abstract: Provided is an aerogel blanket and a method for producing the same, wherein a catalyzed sol I sufficiently and uniformly impregnated into a blanket in an impregnation tank, and the catalyzed sol is allowed to stay in the impregnation tank for a specific time to control fluidity while achieving a viscosity at which the catalyzed sol can be easily introduced into the blanket, thereby forming a uniform aerogel in the blanket. As a result, the uniformity of pore structure and thermal insulation performance of an aerogel blanket are improved, the loss of raw materials is reduced through the impregnation process, the occurrence of process problems is reduced, and the generation of dust is reduced.

Abstract: Multimodal polyolefin resins for manufacturing films, pipes, hollow molded articles having high melt strength and excellent formability, mechanical strength, processability and appearance are described. The resins have: density is 0.930-0.960 g/cm3; melt flow index is 0.01-10.0 g/10 minutes; ratio Mw/Mn is 10-60; and two or more peaks appear when molecular weight is measured by GPC. In molded pipe, the Mw of polymer collected at position B is 0.1% greater than Mw of polymer collected at position A; polymer having Mw of 10,000 or less among polymers collected at position A is 0.1% greater than the amount of polymer having Mw of 10,000 or less among polymers collected at position B; and the amount of polymer having Mw of 1,000,000 or more among polymers collected at position B is 0.1% greater than the amount of polymer having Mw of 1,000,000 or more among polymers collected at position A.
