ring oxygen resin fiber plastics manufacturing methods very more, large upper can separation is mixed method, method and extrusion method 3 type. this 3 type methods 自然各 has advantages, long 处, and versus suitable scope/range, to excellent poor, has 何“本领”? China ring oxygen resin industry expert is 此专门 understanding 疑释惑. ring oxygen resin fiber plastics manufacturing methods is mixed method manufacturing fiber plastics. mixed method is use ring oxygen resin liquid short fiber and filler, mixed combined uniform again 经撕松, dry made fiber plastics, this type of plastics features is: fiber dispersion 且无定 toward, flow property good, output/production volume can large can small; is ratio large, manufacturing process in fiber loss large, strong/high degree reduce, conditions 差. 各工序 can use 手工操 as, suitable for small amount production and made; can use machine as, suitable for large amount production, 手工操 as fiber loss less, products strong/high degree high. China ring oxygen resin industry expert 说, made process in need attention/notes below/following 几点: is fiber 预处理应 using/adopting reinforcement type lubricating agent fiber, 否则需 use hot method remove fiber surface wax lubricating agent, make its amount small 于0.3%, this not only but also fiber strong/high degree reduce, will fiber short, machine mixed fiber long degree ultra- 20～40mm, 手工预 mixed ultra- 30～60mm, fiber 蓬松; is 配胶按 formulation one-time mixed use material amount, use solvent agent amount adjustment liquid tool has combined 适 黏 degree, make in and mixed combined uniform rear 无剩余 胶 liquid ensure plastics amount, usually temperature degree high degree need small 一点, temperature degree low degree need large 一点; is additives other solid additives abrasion fine, 筛, dry to indicators; is and mixed combined need make resin liquid separation fiber and filler mixed combined uniform, amount small can use 手工反复搓揉, amount large can using/adopting z type combined machine; is 撕松, mixed combined uniform rear formed material material need use or machine 撕开, 蓬松, machine main/primary material and for belt/tape 钩齿 撕松辊组 formed, through 撕松辊 反 toward will material 团撕松; is dry will 撕松 预 mixed material uniform in metal upper, 铺层不宜太 thick (generally 约20～30mm), in room temperature lower 凉置, and other large separation solvent agent rear again 进行烘 dry 处理并 make poly to 一定程 degree, temperature degree is 80℃, dry time 20～40min; is 并批, packaging good plastics speed cooling rear, packaging in plastics bag in. methods is method manufacturing fiber plastics, method is will fiber 束整束 through 胶槽浸胶, dry, and other manufacturing fiber plastics methods. this type of plastics features is: formed 束状, comparison 紧密, ratio small, 需 injection molding parts mold add material small, material 简便, production process in fiber loss relatively less, can products force 状态定 toward 铺设模 plastics, can made high strength products, plastics flow property and material 束间 互容 property 稍差, production amount ratio mixed method low. method also can separation is method and machine method, industrial production in generally using/adopting machine 械预浸 method. its in 手工预浸 method 手工预浸 method fiber 预处理, and dry and other requirements and mixed method basic same, fiber long degree is 600～800mm, need 蓬松, liquid versus for density control in 1.00～1.025 scope/range inner. 浸胶时 use copper rod 充当刮胶辊, use 手牵引 fiber 经 两 copper rod between, dry material formed long degree 封存于 plastics bag inner. machine 械预浸 method process process is: fiber from 纱架导出经集束 ring 进入胶槽浸胶, liquid versus for density control in 1.00～1.025, fiber speed degree is 1.2～1.35m/min, fiber rear through 刮胶辊进入第Ⅰ, Ⅱ grade 烘箱烘 dry. 第Ⅰ grade temperature degree is 110～120℃, 第Ⅱ grade temperature degree is 150～160℃, dry material 由牵引辊引出进入切割 machine formed long degree in plastics bag inner. extrusion method is use screw extrusion machine production glass fiber plastics it 克服 预 mixed method and method use a large amount of has machine solvent agent disadvantages, improvement 劳动卫生 conditions, reduce cost, product quality uniform stability can 连续化, 自动化 production, disadvantages is fiber in screw extrusion machine in by abrasion loss, by 剪断 情况 relatively heavy from reduce products strong/high degree, in ring oxygen fiber plastics production in using/adopting. 自: 慧聪网
