现代 full production separation is one-time property injection shot molding and 传统定 type types. below/following 诉 即 is 传统定 type, injection shot 立体初胚, rear 经EVA打 coarse, again 进行定 type as 业. injection shot separation: 仓储配 material, material, 利拿, R0LL操 as, sheet/slice, powder 碎, 抽粒, drying, injection shot, temperature type, water 洗并核 for, packaging 缴库. type separation EVA: material, rate ratio for, abrasion, heavy 检验, 缴库. type: material, type, formed product 检查, 缴库. injection shot separation 一. raw materials formulation 1.以33 degree amount 11D实白EVA material is 例: EP2288; DF810 plastics 粒; DF940 plastics 粒; TT carbon acid 镁, titanium powder; 司 令; ZNO-80母 material; JTR-M50 foaming agent; color 胶; EVA1375红 color formulation function: plastics 粒: raw materials main/primary formed separation. 司 令: external lubricant, easy demolding ZNO-80母 material: reduce foaming temperature degree make can in 140 degree can foaming. agent: make plastics crosslinked generate 空间网状 structure, make material tool has tough property. foaming agent: in hot process in generate nitrogen gas, gas and a small amount of oxidation carbon, make crosslinked generate micro gas 孔. titanium powder, color 胶, 375红 color 胶: through ratio/proportion 搭配, make foaming rear to color requirements. DF810, DF940 plastics 粒, TT carbon acid 镁: improvement material property. formulation reaction mechanism 1. foaming agent hot separation understanding generate nitrogen gas, gas and a small amount of oxidation carbon, make crosslinked generate micro gas tool has elastic property. 2.架桥 agent hot separation understanding generate active 泼 自由基, high poly material hydrogen 离子, make high poly material tool has active property crosslinked formed 立体网状 structure, tool has tough property. 何谓EVA交连 foaming injection shot molding technology? 经由EVA mixed combined formulation utilizing injection shot molding machine and shrink small 模穴以EVA线 property 膨胀之 principle, to foaming molding 体, its in has 熔化, mixed 练, flow, crosslinked, foaming, and shrinkage as, to molding 目. main/primary 包含三 main/primary elements 之互动 injection shot control —— injection molding processing mold design —— formulation stability property 二.领 material good injection shot EVA material 按整手 material in 一起, 并放置 in formulation material 待验区. 检验人员 need for formulation material full 检. material need formulation material is positive 常. material and 检验人员签认ID卡 rear material rear can 领出仓库. 三.利拿 machine 1.工 as principle: 经 两 滚轮转动 and 仓壁挤 pressure function make material to separation solvent understanding and mixed combined 目. 2.操 as 事项: 领出 药 product 需先进先出且需放 in drying can in sheet/plate or wet 方. preheating temperature degree setting is 70 degree. 第一段 mixing/compounding time is 9-10 separation, temperature degree 达100-105 degree. temperature degree 达100-105 degree add foaming agent, agent. 第二段 mixing/compounding time is 3-4 separation, temperature degree 达105-115 degree, can material. more 换材质 or color machine 台清理 dry 净. 四.ROLL machine 1.工 as principle: material through 两 滚桶 between different speed degree generate 之撕拉, make material can more add separation mixed combined. 2.操 as 事项: front lubricated 油泵待 lubricated to 滚轮油槽 rear again 开启马达. temperature degree setting 60-70 degree, 实测不 ultra- 75 degree. 利拿卸 material rear 于ROLL upper thick 6-8mm below/following 翻割两次; 以1.0-1.5mm束 thin rear, again 以6-8mm thick degree 翻割5次 rear material. 五.出 sheet/slice machine 1.操 as 事项: material machine ROLL滚筒 temperature degree setting 60-65 degree, 实测不 ultra- 75 degree. sheet/slice thick degree is 1-1.5mm material sheet/slice long degree 80cm, wide 40cm material sheet/slice formed 6h方 can powder 碎. 六. powder machine material sheet/slice need formed 6h方 can powder 碎. less is 一批进行 powder 碎. machine rear 30秒 inner can material powder 碎, material material need powder can machine, anti 卡死. color need machine 台彻底清理 dry 净, production need cooling water. 七.抽粒 machine 1.工 as principle: material screw rear solvent 化, screw sheet/slice again 由切刀横 toward 切断, cooling water 伴随而出, formed 粒状. 2.操 as 事项: machine production front 需先暖 machine, temperature degree to setting temperature degree 30 separation rear can machine, pressure large formed safety 隐患. temperature degree setting is 1-84 degree; 2-85 degree; 3-85 degree; 4-90 degree; 5-85 degree; 6-90 degree; 7-90 degree. cooling water temperature degree 50 degree below/following, material large small need uniform. machine front need screw inner EVA production 完. 八. drying material: 35-40 degree; time: 30-240 separation 钟. material must has table/sheet 格记录九. injection shot conditions production type requirements setting: 以2210 is 例: injection molding processing mold temperature degree 165 degree positive negative 5 degree; holding pressure time: 300秒. use 剑布, sheet/slice and gas 枪清理 injection molding processing mold. again use type agent spray coating rear, can clamping function. 十.恒 temperature 烘箱1.工 as principle: type according to temperature testing device temperature degree 进行工 as, 当实际 temperature degree low setting temperature degree, add hot tube/pipe add hot, 反之则 versus 反, utilizing 风扇排出 hot amount, control speed degree make temperature degree 始终于 stability lower. 2.操 as setting: separation is 60-55-50-45-40. positive negative 3 degree; speed degree 45-46 separation 钟. 3.操 as requirements: formed product need in 3秒 inner injection molding processing mold, 18秒 inner 送入烘箱. 十一.PH water 洗1. water temperature degree 35-45 degree. pressure kg/cm2 above. gas pressure 4-7kg/cm2 2. formed product water machine rear, light light 敲打掉 water 珠, rear for sheet/plate ratio for formed product rate. 3. packaging 时, prohibited mixed mixed phenomenon. type separation 一.EVA组2.领 material material upper 班时10 separation inner, type amount table/sheet to type 员工, abrasion rear formed product, good material 帐目. material 员按规定 ratio/proportion, 送初胚进行倍 rate for. IPF: 20% long degree requirements positive negative 2mm, wide degree requirements: positive negative 2mm. material upper in 间随时补足EVA and type semi products, ensure efficiency 发挥. 3. machine as 1.研 abrasion tool, EVA and to 麻布轮 and 砂轮两 types. 2.操 as methods: (1)安装 abrasion 轮A. abrasion 布轮安装时 use 3-4 block, can according to 人习惯 or type abrasion different more 改, 目 就 is can make speed degree and quality more good 发挥. B. new abrasion in use 时, need remove 反面 底线, again in positive 面拉掉余线, new abrasion 布轮即 can 安装, use 初胚试 abrasion lower can has 麻毛. C.砂轮安装时 use 1 即 can, separation coarse or fine 纱, type sample requirements is 准. need abrasion 出肉身 relatively thick use coarse 纱轮, 反之则 use fine 纱轮. (2)操 as A.砂轮: 进行初 processing, type sample and technology 课描述之 key points, 进行研 abrasion. force degree need 适当, use force degree and abrasion 掉 初胚肉身 thick degree formed positive ratio. ( use force degree is key/critical )B.麻布轮: 进行精 processing. and type rear formed product appearance and 砂轮研 abrasion 处, must 以麻布轮 again abrasion. 边墙处应倒出圆角, requirements 平而顺, is type quality key/critical in. type 时, especially is color different type, abrasion powder and machine 台卫生一定 need dry 净. abrasion formed product, has 任何尖角处, need saturated 满且圆顺. (平 sheet/plate foaming: has 裁断之断面痕). has or material surface. C. lower rear, EVA员工 will abrasion lower, method use abrasion need and more 换. 4.缴库: material 员于线 upper 收取研 abrasion rear formed product, in material material to type. 按规定 ratio/proportion, add 硫室进行检验. ( hardness, important, and density ). 5. quality and improvement. 因初胚研 abrasion quality and type has very large 关系, many issues is need to type rear can 看出, quality Common type quality and improvement in detailed 记述. 6. use tool and 劳保工 tool: 麻布轮, 砂轮, 禅子, 箩筐. 劳保: 帽子, 围裙, anti 护镜, 耳塞, anti 尘口罩. 二.定 type 组2. machine maintenance A.定 type machine less has 3 block injection molding processing mold can upper rise, active ultra- long, liquid pressure 油溢出.
