tdi可以做现货期货吗
1. TDI{甲苯二异氰酸酯}用的是啥金属催化剂
做聚氨酯吗?通常用四丁基锡做催化剂,不是金属,是金属有机物。
生产TDI有光气法和非光气法,通过相关文献来看,光气法没有用到什么特殊的有毒催化剂,反而是原料光气(COCl2)具有剧毒。而非光气法催化剂通常是醋酸盐,没有什么毒性。
2. 化工TDI是什么TDI装置是什么看有公司招聘TDI装置工艺工程师招聘,不理解说化工机械范畴吗还什么
TDI是甲苯二异氰酸酯的英文缩写
生产方法:由甲苯硝化生成二硝基甲苯,再经还原得到甲苯二胺。甲苯二胺与光气反应即得TDI(以2,4-异构体为主)。
TDI装置工艺工程师的岗位职责:
1、 协助装置经理做好质量管理和成本优化,及时发现和处理工艺异常,确保产品质量稳定;
2、 参与新工艺、新技术方案的论证、设计、施工、试车工作;
3、 协助装置经理培训班员, 不断提高班员的操作水平
国内企业:
沧州大化集团有限责任公司(600230)
甘肃聚银化工有限公司
中国蓝星集团
山东巨力股份有限公司(000880)
3. 关于TDI的3个月为一周期,必须做保养问题!
5000首保,以后每7500一保
4. 什么是TDI,MDI的用途
TDI,即甲苯二异氰酸酯,有2,4-甲苯二异氰酸酯和2,6-甲苯二异氰酸酯(TDI)两种异构体,主要用作聚氨酯软质泡沫、涂料、橡胶、纤维、胶粘剂的原料。
MDI是二苯甲烷二异氰酸酯,是一种有机物,是芳烃下游主要产品,广泛应用于聚氨酯弹性体,制造合成纤维、人造革、无溶剂涂料等聚氨酯材料的生产领域。
(4)tdi可以做现货期货吗扩展阅读:
甲苯二异氰酸酯容易与包含有活泼氢原子的化合物:胺、水、醇、酸、碱发生反应,特别是与氢氧化钠和叔胺发生难以控制反应,并放出大量热。与水反应生成二氧化碳是聚氨酯泡沫塑料制造过程中的关键反应之一,应避免受潮。
用二苯甲烷二异氰酸酯制成的聚氨酯制品由于已经显示出高的抗撕裂强度,耐低温柔软性,低导热系数等良好的化学稳定性等特点,被广泛地用于生产聚氨酯合成革,人造革涂层、聚氨酯软泡、硬质泡沫等,特别用于建筑材料。
5. TDI是做啥用的
TDI是英文Turbo Direct Injection的缩写,意为涡轮增压直接喷射(柴油发动机)。 为了解决SDI的先天不足,人们在柴油机上加装了涡轮增压装置,使得进气压力大大增加,压缩比一般都到10以上,这样就可以在转速很低的情况下达到很大的扭矩,而且由于燃烧更加充分,排放物中的有害颗粒含量也大大降低,TDI技术使燃油经由一个高压喷射器直接喷射入气缸,因为活塞顶地造型是一个凹陷式的碗状设计,燃油会在气缸内形成一股螺旋状的混合气。 大众集团首创的直喷式涡轮增压柴油发动机(TDI)技术十分先进,而且采用了多项先进技术,例如泵喷射系统、可调叶片式涡轮增压器等等都是首次在国产轿车上应用。大众TDI采用了最新的高压燃油喷射技术---泵喷射系统。此系统使柴油与空气混合更充分,燃烧更彻底;同时采用氧化型催化反应器,大大降低了CO、HC、颗粒的排放,其中CO2排放与同排量汽油车比可降低30%。另外,采用EGR系统,大大降低了NOx产生,其排放指标满足欧3标准。
6. TDI能替代MDI来做固化剂么
可以。但用料不同。
7. MDI TDI 是甲类危险化学品还是乙类危险化学品
毒鼠强等5种禁用剧毒化学品任何人,任何情况下禁止做,不能做,不许做,不许买,不许卖,不许存,不许用 ,否则要触犯刑法125条第二款. MDI,TDI,三氯氧磷,红矾钠等 是其他一般剧毒化学品.按危险化学品管理条例,生产要许可证,使用要备案,规定做,限制做, 限制买,限制卖,限制存,限制用,否则触犯危险化学品管理条例,要限期整改,拒不整改的要按行政处罚法,罚款. 中华人民共和国最高人民法院祝二军处长博士"<<关于办理非法制造、买卖、运输、储存毒鼠强等禁用剧毒化学品刑事案件具体应用法律若干问题的解释>的理解与适用> 道出了立法的本意.但下面公安部门把335种剧毒化学品,如生产大量用的液氯 三氯氧磷 红矾钠 TDI等化工原料偶尔触犯危化管理条例的都往刑法125条第二款套,先来一个取保候审.冤屈,影响生产不说,浪费司法资源呀!!

8. TDi80和MR200加聚醚做成的固化剂,为什么固化后会很脆,没有韧性和弹性,请教各位懂的专家解答
下午好,TDI和聚醚都属于硬段分子结构,如果你实现聚合反应用的是聚酯多元醇就容易出现这种情况和PU清漆一样,芳香族异氰酸酯本来就要比脂肪族共轭强度更大,你换成THF开环缩聚的聚醚多元醇我想应该会变得柔软一些。TDI和做列克纳胶水的TTI相近固化后除非做中空发泡通常都是缺乏弹性模量的。
9. tdi100与tdi80做出的聚氨酯弹性体在性能上有何不同
tdi100与tdi80做出的聚氨酯弹性体在性能上不同有TDI-100主要应用于高品质聚氨酯弹性体的生产,从一定程序上解决了TDI80/20反应速度过快不易操作的问题,容易制成透明的制品。
TDI全称Toluene-2,4-diisocyanate;2,4-tolylene diisocyanate是甲苯二异氰酸酯的英文缩写。
TDI(甲苯二异氰酸酯)是常用的多异氰酸酯的一种,而多异氰酸酯是聚氨酯(PU)材料和重要基础原料。聚氨酯工业常用的TDI是2,4-TDI和2,6-TDI两种异构体的混合物,包括3种常用的牌号:TDI-80/20,TDI-100和TDI-65/35。前面的数字表示组成中2,4-TDI的含量。比如TDI-80/20中的80表示其组成为80%的2,4-TDI和20%的2,6-TDI;TDI-100中的100表示基本上都是2,4-TDI(约98% ),2,6-TDI的异构体很少。主要用于生产软质聚氨酯泡沫及聚氨酯弹性体、涂料、胶黏剂等。
TDI在装修中主要存在于油漆之中,超出标准的游离TDI会对人体造成伤害,主要是致敏和刺激作用,出现眼睛疼痛、流泪、结膜充血、咳嗽、胸闷、气急、哮喘、红色丘疹、斑丘疹、接触性过敏性等症状。国际上对游离TDI的限制标准是0.5%以下。
甲苯二异氰酸酯为无色或淡黄色有刺激性臭味的透明液体,在紫外线照射下变黄;在合金钢容器中加热易聚合;能与羟基化合物中的羟基、水、胺及具有活泼氢的化合物反应生成氨基甲酸酯、脲、氨基脲及双缩脲等。
