Title: Acrylic self-adhesive composition
Inventor: TSUBOTA KENJI
IPC: C09J133/04
Filed: 1988-06-25
Abstract: PURPOSE:To obtain a self-adhesive composition which has excellent adhesiveness, cohesive force and heat resistance and can prevent an adherent and a support from being hydrolyzed by adding a dialkylamine or a trialkylamine to a specified acrylic copolymer. CONSTITUTION:The title self-adhesive composition is formed by adding 1-20 pts.wt. dialkylamine or trialkylamine (each alkyl group having at least 4C) to 100 pts.wt. acrylic copolymer formed by copolymerizing 85-97wt.% (meth) acrylic ester with 3-15wt.% carboxylic compound. When the proportion of the carboxylic compound in the copolymer is lower, the cohesive force of the adhesive decreases. When it is higher, the adhesiveness decreases and the adhesive accelerates the hydrolysis of an adherend or a support. When the proportion of the dialkylamine or trialkylamine is lower, the effect of the carboxylic compound on the prevention of hydrolysis decreases. When it is higher, the adhesive softens and its adhesiveness and cohesive force decrease.

Inventor: KURITA GORO
IPC: B01J2/10
Filed: 1984-07-30
Abstract: PURPOSE:To prevent the stagnation of a fluid by positively discharging the fluid by buffle, in a stirring tank for granulating an aqueous coal slurry and a binder under stirring, by providing the buffle in the vicinity of the discharge port side of said stirring tank so as to be capable of moving the same from the upstream side of said discharge port to the downstream side thereof in the rotary direction of a rotary blade. CONSTITUTION:At a steady time, bubbles 5 are positioned at points A being the upstream sides with respect to a discharge port 16 in the rotary direction of rotary blades 2 to rotate said rotary blades 2. When the flowing of an aqueous coal slurry becomes liable to stagnate, a motor 11 is positively rotated and the buffles 5 are moved to points B by a shaft 9, a pinion 10 and a buffle support 7. Each point B is positioned in the downstream side of the discharge port 16 in the rotary direction of the rotary blades 2 and the aqueous coal slurry is easily discharged. When stagnation behavior disappears, the motor 11 is rotated reverserly to return the buffles 5 to the points A. The judgement of stagnation is performed, for example, by the flow amount from the discharge port 16 and the motor current of an electromotor 3.
