    摘要： A method of producing an adhesive resin includes: a heating and kneading step of kneading a mixture containing a ring structure-containing hydrocarbon resin, an adhesive functional group-containing compound, and a peroxide while heating the mixture to obtain a heated and kneaded product; and a cooling and kneading step, performed in succession to the heating and kneading step, of kneading the heated and kneaded product while cooling the heated and kneaded product to obtain a cooled and kneaded product. The adhesive resin has a yellowness index (Yi) of 3.0 or less when 0.8 parts by mass of 2-(5-chloro-2-benzotriazolyl)-6-tert-butyl-p-cresol is added to 100 parts by mass of the adhesive resin.

    摘要： An ultralow-gloss polycarbonate/acrylonitrile-butadiene-styrene (PC/ABS) resin composition and a preparation method thereof are provided. The composition includes the following components: 40-80 parts by weight of bisphenol A polycarbonate, 19-40 parts by weight of acrylonitrile-butadiene-styrene graft copolymer, 1-20 parts by weight of ultralow-gloss toughening modifier, and 0.1-5 parts of processing aid. The ultralow-gloss toughening modifier includes the following components: post-treated polymeric microspheres, a low-temperature toughening agent, a coupling agent, and aid. The preparation method of the composition includes: fully mixing all components in a high-speed mixer to obtain a mixture; feeding the mixture into a main feed port from a twin-screw extruder, melting, extruding, cooling, drying, and pelletizing. The PC/ABS resin composition prepared by the present invention has extremely low gloss level and excellent impact toughness, and it can be applied in scenarios requiring low temperature resistance and low gloss level.

    摘要： A gravimetric blender has a frame, at least one material storage hopper at the top of the frame including a hopper cover, a weigh bin located within the frame, below the hopper, for receipt of material from the hopper to be weighed and being adapted for downward discharge of the material in the bin after the material received from the hopper has been weighed, at least one load cell connecting the weigh bin to the frame for sensing the weight of contents of the weigh bin, a mixer within the frame below the hopper, for mixing material weighed in the weigh bin after that material falls downwardly from the weigh bin to the mixer, and a guide adapted for vertical movement of the hopper cover therealong between positions which the cover contacts and thereby closes the hopper and at which the cover is spaced vertically but maintained in a horizontal plane above the hopper so that the hopper is open at the top.

    摘要： To improve the work environment by preventing a larger amount of a powder compounding agent from being discarded as power dust and by returning the powder compounding agent into a kneading tank by capturing said powder compounding agent by employing a simple means in closed pressure type kneader. Also to bring the compound quality closer to the design quality by drastically increasing the valuable collection rate. A recovery device for collecting an ejected powder compounding agent is installed on a closed pressure type kneader for kneading a kneading material along with a powder compounding agent in a kneading tank by rotating a kneading rotor. In the recovery device, a tubular air bag capable of expanding and contracting is connected to the side surface of the surrounding wall of the kneading tank with a ventilation chute between the air bag and the surrounding wall, the surrounding wall surrounding the periphery of a pressurized lid rising/lowering path. A branching duct capable of connecting to and being disconnected from the outside is connected to the top of the air bag, and a filter tube for filtering and capturing the powder compounding agent carried by a gaseous body flowing from the side of the kneading tank is disposed in a suspended manner within the air bag. As a consequence, it is possible to return the powder compounding agent captured by means of the filter tube to the kneading tank by means of the pressurized air flow accumulated in the air bag.

    摘要翻译： 为了通过防止大量的粉末混合剂作为动力粉尘被丢弃并通过在闭式压力式捏合机中采用简单的方法捕获所述粉末混合剂将粉末混合剂返回到捏合槽中来改善工作环境。 同时通过大幅增加宝贵的收集率，使复合质量更接近设计质量。 用于收集喷出的粉末混合剂的回收装置安装在用于通过旋转捏合转子将混炼材料与粉末混合剂一起捏合在捏合槽中的密闭型捏合机上。 在回收装置中，能够膨胀和收缩的管状气囊与气囊和周围壁之间的通风槽连接到捏合槽周围的侧面，围绕加压的周边的周围壁 盖上升/下降路径。 连接到外部并与外部断开的分支管道连接到安全气囊的顶部，并且设置用于过滤和捕获由从捏合槽侧流出的气体携带的粉末混合剂的过滤管 以悬挂的方式在气囊内。 因此，可以通过积聚在气囊中的加压空气流将通过过滤管捕获的粉末混合剂返回到捏合槽。
