    • PURPOSE: A foam styrene resin producing device is provided to adjust the size of a resin particle conveniently and simply, and to improve productivity by saving energy and reducing a cycle. CONSTITUTION: A foam styrene resin manufacturing apparatus is composed of a pure water tank(10) supplying pure water; a styrene monomer tank(11) supplying a styrene monomer; a distributing tank(12) supplying various additives; a foaming agent tank(13) supplying a foaming agent; a preliminary polymerizing tub(14) and a screw feeder reactor(15) for pre-reaction; a main polymerizing tub(16) such as a main reactor; a cooling circulator(17) cooling and aging; a drum screen(18) washing; a sludge tank(19) such as a temporary storing place; a centrifugal separator(20) and a dehumidifying system(21) for dehydration and dehumidification; and a dehumidifying drier(22) operating at a final step. Various additives are added in pre-reaction, screw feeder reaction and main reaction steps. The main stage reacts with two steps according to temperature. A proper additive is added according to the reaction step to compensate the defect between the physical properties of foam styrene resin. The particle is obtained over 94% with adding a resin particle control agent and a dispersing agent in the main reaction step, and with changing the stirring speed.
    • 目的:提供一种泡沫苯乙烯树脂生产装置,方便简便地调节树脂颗粒的尺寸,并通过节约能源和减少循环来提高生产率。 构成:泡沫苯乙烯树脂制造装置由提供纯水的纯水罐(10)组成; 提供苯乙烯单体的苯乙烯单体槽(11) 供应各种添加剂的分配罐(12) 提供发泡剂的发泡剂罐(13) 用于预反应的预聚合桶(14)和螺旋进料反应器(15) 主聚合槽(16),如主反应器; 冷却循环器(17)冷却和老化; 滚筒筛(18)洗涤; 诸如临时存放处的污泥池(19); 用于脱水和除湿的离心分离器(20)和除湿系统(21); 和在最后一步操作的除湿干燥器(22)。 在预反应,螺旋进料反应和主反应步骤中加入各种添加剂。 主要阶段根据温度进行两步反应。 根据反应步骤添加适当的添加剂以补偿泡沫苯乙烯树脂的物理性能之间的缺陷。 在主反应步骤中添加树脂颗粒控制剂和分散剂,并且改变搅拌速度,获得超过94%的颗粒。
