玻璃钢管生产工艺重要有三品种型:往复式纤维环绕纠缠工艺、一连式纤维环绕纠缠工艺和离心浇注工艺。
There are three main types of FRP production process: reciprocating filament winding process, continuous filament winding process and centrifugal casting process.
往复式纤维环绕纠缠工艺(属于定长法):正在这类工艺要领中,浸胶槽随迁移转变的芯模作往复活动,少纤维玻璃丝以肯定的斜角相对芯模轴辅放,辅角(即环绕纠缠角)受浸胶槽的挪动速度和芯模转速之比掌握,浸胶槽的平移活动由计算机化的机-电掌握。环绕纠缠层数逐步增添,到达设想的壁薄为止。环绕纠缠完成后,使成品中的树脂根基固化。固化后,从玻璃钢管中脱出芯模。
Reciprocating filament winding process (belongs to length method): In this process, the dipping trough moves reciprocating with the rotating mandrel, the long fiberglass filament is placed with a certain oblique angle relative to the mandrel axis, the auxiliary angle (i.e. the winding angle) is controlled by the ratio of the moving speed of the dipping trough to the rotating speed of the mandrel, and the translation motion of the dipping trough is controlled by computerized machine-electricity. The number of winding layers increases gradually until the designed wall thickness is reached. After winding, the resin in the product is basically cured. After curing, the core die is removed from the FRP pipe.
一连式纤维环绕纠缠工艺(属于一连法) :该工艺是管子正在活动中经由过程一个供应树脂预浸无捻粗纱,短切玻璃钢纤维和树脂砂混合物的供料站,管子是正在芯模时断时续的行进中制成的。
Continuous filament winding process (belongs to continuous method): This process is a pipe in motion through a feeding station for resin prepreprepreg roving, chopped fiberglass reinforced plastic fiber and resin sand mixture, the pipe is made in the continuous progress of the core mould.
离心浇注工艺(属于定长法) :正在此工艺中,用割断的玻璃纤维加强质料和砂,喂入流动正在轴承上的钢制模具中,正在钢模一端注入加催化剂的不饱和树脂,使其浸渍加强质料,正在离心力感化下,树脂置换出纤维及填料中的氛围,从而制造出无孔隙的致密复合材料,因为离心力的感化管内壁构成一个腻滑、光亮的富有树脂的内外面层,管材正在较下温度下固化。用这种方法制造的管又称玻璃钢夹砂管。
Centrifugal casting process (belonging to length method): In this process, cut glass fiber reinforced materials and sand are fed into the steel mould on the bearing, and unsaturated resin with catalyst is injected into one end of the steel mould to impregnate the reinforcing material. Under the action of centrifugal force, the resin replaces the air in the fibers and fillers, thus producing porous and compact composite materials. A smooth and smooth resin-rich inner surface layer is formed on the inner wall of the tube under centrifugal force, and the tube solidifies at a higher temperature. The pipe manufactured by this method is also called FRP sandwich pipe.
世界上接纳往复式纤维环绕纠缠工艺造管的厂家比别的两种生产工艺生产厂家多的多,缘由之一是往复式纤维环绕纠缠工艺制造的玻璃钢管具有更普遍的用处,适用性对照好。
There are more manufacturers using reciprocating filament winding process than the other two processes in the world. One of the reasons is that the FRP pipe manufactured by reciprocating filament winding process has a wider use and better applicability.
