transparent separation is 2 types, types is semi transparent 橡胶, 俗城牛筋底. types is pure transparent 橡胶, 俗称玻璃胶. 今天我们 main/primary semi transparent formulation and process. full 国 工 injection molding parts processing in production 牛筋底, can is can true positive according to process process/workflow as, can to formulation setting value has 几家. causes in is is cost, is positive process process/workflow to how 做. large separation in 抄别人, need color can 接近, can to semi transparent good. 今天我 讲 is types can to formulation setting formulation and process process/workflow, is frame 架基础, can made as to upper 2000 year left right water material property standards. meanwhile can to made as NIKE and ADI and other product standards. is 何说无 method to currently most new water 平, is is material and 我们 理念 限 made. 一． 材 material. material for material property effect/influence is non important. currently 我国 橡胶材 material development non large. basic upper general purpose material can to 90 year 代 国际 water 平. different injection molding parts processing 家 材 material quality very large. large in use carbon 黑, has need 6000元一吨, has has 3000. if material property good product, selection positive production injection molding parts processing product. to 我印象 most deep is 原先我 in outer injection molding parts processing 厂 时候, testing testing formed product water 洗实验, must use USA Brand powder testing. and year time is 如此. is China powder quality good 吗? is, is 追求 一 stability property. Raw Materials can can more 花一点钱, is in production in decrease/reduce, product decrease/reduce, is versus 当于省钱. generally injection molding parts processing in solution production 异常 方面花 心思 most more, most 烦心. large 家应该都 has upper 连夜不睡觉 处理 issues 情况. 二． formulation China made 鞋橡胶 injection molding parts processing most what? technology! large 家都应该 has 同感, is good 师傅, requirements 人, is good formulation, need large 钱! full 职, 就请兼职. is Raw Materials technology 指导, also need 花钱买 Raw Materials 商 材 material and other and other. excellent RB formulation must meanwhile combined basic requirements: material property, cost and processing property this most balanced. must more excellent 选并经 amount 产考验才 can most rear formulation formed. formulation design is non complex as, design formulation need according to requirements material property indicators combined selection and combined agent, meanwhile requirements design 者熟悉 various as machine features, comprehensive amount, meanwhile need environmental protection and other factors. currently overall formulation technology water need rear water 平30-40 year. is understanding front technology industrial is 空白, understanding rear also 遭受 文革 and other parts, and other to 我们回 头 才发现, already rear more. lower 面我们 specific lower 牛筋橡胶 formulation formed 1. positive 常搭配应该 is 天然橡胶NR or IR搭配丁苯橡胶 and 顺丁橡胶 system, is 以顺丁橡胶 is system. currently large separation injection molding parts processing also in using/adopting 以天然 and 丁苯橡胶 is system, causes is 顺丁橡胶 in 60 year upper start production, China 67 year 才开始 start production, this positive is 文革时期, China technology to 灭顶之灾. 根本没 has research this new material use. in a large amount of made 鞋橡胶 injection molding parts processing 举办 初期, has injection molding parts processing 老师傅 has several formulation to outer 面, large 家依照 做. true positive technology development is outer 资进入 China rear, outer technology outer 流造就 China made technology. therefore China made 鞋业应该感谢 outer 资. simple formulation 主胶搭配 例子 NR/IR 20-30 国际都 use Malaysia standards 橡胶. inner large separation use 3L标胶. if manufacturing shallow color products, can use IR胶. SBR/SSBR 10-20 generally use 1502. solvent poly use 1205 or 1430 and other. BR 60-70 generally use 9000. outer more use BR0150 and other. this system advantages: 1. to force, force, elastic property, abrasion consumption. various has features, will its comprehensive 起, can long short. 2. 以BR胶 is 主体, filling agent and type use amount can high very more, can reduce cost material property reduce obvious. 3. BR胶 abrasion consumption non good, for wear resistance improves has non large 帮助. 4. 以顺丁橡胶 is formulation, promote agent use amount need ratio 丁苯橡胶 is less 1/3 left right. can reduce cost, reduce promote agent use amount large 会引发 吐霜 and other 异常. 5. 顺丁橡胶 elastic property in general purpose 橡胶里 most good, formed shoe sole easy deformation. 顺丁橡胶 is formulation meanwhile another issues, is wear resistant slip, especially is BR胶会 generate wet slip. this 时候就 need 搭配另一 types 丁苯, solvent poly 丁苯橡胶. 此橡胶 has non excellent resistant slip property. large 家都知道 high 档 玻璃胶不打 slip, is is 里面并 use solvent poly 丁苯橡胶. 2. filling agent: made as semi transparent use carbon can to 效果. carbon 黑(SiO2*XH2O): is formulation in use most filling agent, in formulation in use amount generally is 30-60PHR between,目 is reduce cost, improve/increase material strong/high degree, reduce material flow property. carbon quality 直接关系 to material property. upper 普通白 carbon generally standards lower: surface 积: large 于175平方米/克 PH value: 6-7.5 moisture content 5-7% pure degree large 于98% 白 carbon surface large, 说明补 strong/high property can good, for material material property improves large, 反之胶 material hard, has tough property, material sheet/slice very difficult. acid alkali degree very key/critical, if unstable 话, has production 时会发现 has very fast material, has also 不熟. 3. active property agent active property agent （ also promote additives ）: is use promote agent reinforcement active property and can, most commonly used is zinc oxygen powder （ carbon acid zinc ）/ hard acid (1).司 令(hard acid): and zinc oxygen powder combined solvent rear formed hard acid zinc,因 hard acid zinc has slip lubricating features can demolding, improvement roll太 viscous as property,但 use more effect/influence rear processing viscous ． positive commonly used amount is 1PHR. (2) zinc oxygen powder （ZnO）: in formulation in remove is add active property agent outer,也 provide relatively high hot rate, for thick products or thick thin products effect/influence large. positive commonly used amount is 4-5PHR. hard acid and zinc oxygen powder active principle: zinc oxygen powder + hard acid ----> hard acid zinc hard acid zinc + promote agent ----> hard acid zinc / promote agent combined 体 硫磺+熱-------> active 化硫磺 hard acid zinc / promote agent combined 体 橡胶+s---------------------------->硫化橡胶 in 牛筋底 material in generally use transparent zinc oxygen powder: pellets more fine,折 light rate and 普通橡胶 versus 近, transparent property 佳. use amount can ratio oxidation zinc use amount micro less 一点. (3) alcohol amine active property agent increase PH value in and acid property, active 化白烟 surface, reinforcement 白天烟 and separation 子 结 combined Ａ．DEG active property agent (ethylene glycol, easy wet). shoe sole formulation use amount 约60-80克/公斤白烟, main/primary according to acid alkali degree 决定. positive 常PH value 為 6-7.5范圍內.PH value small, ethylene glycol use amount large. attention/notes DEG use amount, more will 导致胶 material alkali property, effect/influence time and promote agent promote 效果. B. PEG active property agent (poly ethylene glycol ） 先进 formulation use PEG+1987(尿素 type,脂肪 acid type mixed combined material) 取代以往之DEG promote agent system, its 目: scorching/burn marks issues. is solid 状,避免DEG liquid 状磅秤 upper 之困扰. 避免DEG因吸 wet 而导至 dispersion defect and hot pressure time unstable 之困扰. DEG can can 导致健康 issues. silicon type coupling agent 如SI-69 main/primary as used for carbon and 橡胶结 combined. can separation is active property agent. anti agent:也称之 is anti agent is 避免橡胶 in use process in to outer and oxygen 攻击以 and hot metal catalytic,屈曲运动之 effect/influence 而发生橡胶 surface crazing,发 viscous, hardness increase or reduce and other poor 化情形, in formulation in combined add 2-3 types (a small amount of)老 anti agent make surface formed film more increase its resistant oxygen and other 侵害,以达 to multiple different function,但 amount more formed 吐霜． 普通 牛筋 material can use SP anti agent, 但SP会 effect/influence transparent degree, that 么我们 selection transparent degree good 264就 can. use amount 1份. meanwhile need micro wax and other. add wax is let it 吐出 覆 cover/cap in surface formed 隔离层. 隔绝臭 oxygen for 橡胶 破 bad. use amount need more, 0.5份就够. if more, for viscous effect/influence very large. promote agent generally injection molding parts processing promote agent use amount very large. its combined 理搭配 use amount can decrease/reduce 1/3, but also as more 方便. 如: DM 1.2份 M 0.2份 TT/TS 0.2-0.3份. 我建议 promote agent D less add or add. is D tool has very large property. add less can in and DM and M. improve/increase it active property, if add ultra- 0.5份, 就会抑 made DM and M 效果. if non need add, 我建议不 ultra- 0.3份. or 者换一 types promote agent system: CZ/NS 0.8-1.0份. TT/TS 0.2-0.3份. use amount solid in 1.5-2.0份 between. according to above 点评, can 出牛筋 material basic formulation lower: standards: abrasion consumption 阿克隆0.4 below/following, hardness 65 degree positive negative 3 degree. force large 于100公斤/平方 cm. elongation large 于400%, force large 于35. 300%拉 force large 于35. outer aging ensure 2 year. 天然橡胶 or IR 25 SBR/SSBR 10 BR 65 白 carbon 黑 50 PEG/DEG 4-5 carbon acid zinc 4.5 hard acid 1 油 3 DM 1.3 M 0.2 BHT 1 micro wax 0.5 TT/TS 0.2-0.3 S 2 请 large 家记住 this formulation. is most 先进 牛筋 material formulation system skeleton/framework. process process/workflow has good Raw Materials, has good formulation is formed 功 一 semi, lower 我们谈一 lower process process/workflow control. 一． 密炼 machine material precautions: 1. 顺序. from upper 考虑, material separation is 3段. 第一段, mixing/compounding, time 2 separation 钟, temperature degree control in 80 degree below/following. is what need mixing/compounding uniform rear can add powder 呢? is has mixing/compounding uniform add powder, different mixed powder type ratio/proportion is different. formed filling agent non-uniform. 第二段, add 入2/3 白 carbon and powder type type. mixing/compounding 2 separation 钟. temperature degree control in 100 degree below/following. 第三段, add 入1/3 白 carbon and promote agent type. mixing/compounding 2 separation material. temperature degree control in 130 degree below/following. machine most good to 120 degree above material.因 is combined agent large separation need solvent understanding in 里面才 can to most good 效果. if solvent understanding good, that promote agent 效果受 effect/influence. that need more add. add more 你说会 how 样? another dispersion good 话, formed in 橡胶里面也会迁移 呀. material good what to do? very more injection molding parts processing method is cooling rear add pressure 鞋子. its 实, most good is can let material cooling rear 停放24H rear again add 硫. is in high speed machine function lower, separation by very dispersion 乱, need time let separation heavy new polymerization, and combined agent and other in material in has again uniform process. can obvious improve/increase material tough property. 同样, add rear micro several small again production comparison combined 理. 二． hot pressure temperature degree large separation injection molding parts processing less 则155 degree above, more can to 170 degree, can 90秒出模. this 样也怪不 异常 more. positive high temperature fast speed system is 145-155 degree between, time 5 separation.因 is Raw Materials and additives and other is according to this standards production, ultra- 话 for material property very large. high temperature make material function. solution 之 吐霜. causes non complex, 总 说 also is combined agent solvent understanding degree issues. 我列举 一 我们 commonly used combined agent most high use amount, and large 家共同 discussion lower. what add! this can can. 2. less add, combined add. what combined add? shoe sole additives positive as safety use amount lower DM 1.5份 below/following more 浪费,会吐出., M 0.3份 below/following more very easy material, especially is more difficult as. D 0.3份 below/following less can active promote agent 效果, more made promote agent 效果,而 且污染 very heavy. CZ/NS and other 1份 below/following TT/TMTM 0.2份 below/following more force 差, material S 2份 below/following 油 5份 below/following, most good add. if non need add amount ultra- 10份, ultra- rear full ensure. hard acid 1份 below/following add more 会跑出. oxidation zinc / carbon acid zinc 5份 below/following anti agent 1份 below/following 1份 positive can ensure 2 year positive aging. wax 0.5份 below/following DEG/PEG 60-90克/公斤 coupling agent 0.3-1份 1份 already can non good material property. more add 改变不 large. DCP 1.5份. dispersant 1份 resin amount add. anti promote agent has promote agent can anti 吐霜. has combined combined combined 理. mixed combined promote agent amount need use. has 1/3 M in 里面,夏天 difficult 做呀,不 need good. carbon acid how much can,但 need attention/notes and carbon acid alkali combined. good product, need excellent Raw Materials, excellent combined formulation, machine equipment and 军事化 tube/pipe lower 严谨 操 as can formed. currently has in small type made 鞋橡胶 injection molding parts processing in technology content low lower, formulation combined 理, process/workflow specification formed quality very 差, can consumption large, large phenomenon. in 60-70 year water upper. 归根结底, also is technology development force amount thin low formed. in made 鞋业存 in large low 点. is force 资源缺乏, tube/pipe 理, R&D, design 人才引, 留不住, 熟练工人不足. is injection molding parts processing innovation can force low, in small injection molding parts processing large separation still 以仿冒抄袭 is 主, product 同质化严 heavy, property small. is 缺乏自己 export Brand, type export large more belongs to material processing, processing, production, true positive belongs to 自己 独立 Brand export relatively less. is export market versus for in, product 定位趋同化, injection molding parts processing 厂间存 in competition versus pressure 价. temperature and 晋江两 鞋 injection molding parts processing and injection molding parts processing more 达数千家, in recent years trend is 不断 倒闭一 small type, competition force injection molding parts processing 厂. large in 感叹生意 difficult 做. 诚然, large ring for made 鞋业 转移 is 一方面, meanwhile 也暴露出我们 in small type made 鞋橡胶 injection molding parts processing milli competition force, method 拿 出 good product.
