1. TDI{甲苯二異氰酸酯}用的是啥金屬催化劑

做聚氨酯嗎?通常用四丁基錫做催化劑,不是金屬,是金屬有機物。

生產TDI有光氣法和非光氣法,通過相關文獻來看,光氣法沒有用到什麼特殊的有毒催化劑,反而是原料光氣(COCl2)具有劇毒。而非光氣法催化劑通常是醋酸鹽,沒有什麼毒性。

2. 化工TDI是什麼TDI裝置是什麼看有公司招聘TDI裝置工藝工程師招聘,不理解說化工機械范疇嗎還什麼

TDI是甲苯二異氰酸酯的英文縮寫
生產方法:由甲苯硝化生成二硝基甲苯,再經還原得到甲苯二胺。甲苯二胺與光氣反應即得TDI(以2,4-異構體為主)。
TDI裝置工藝工程師的崗位職責:
1、 協助裝置經理做好質量管理和成本優化,及時發現和處理工藝異常,確保產品質量穩定;
2、 參與新工藝、新技術方案的論證、設計、施工、試車工作;
3、 協助裝置經理培訓班員, 不斷提高班員的操作水平

3. 關於TDI的3個月為一周期,必須做保養問題!

5000首保,以後每7500一保

4. 什麼是TDI,MDI的用途

TDI,即甲苯二異氰酸酯,有2,4-甲苯二異氰酸酯和2,6-甲苯二異氰酸酯(TDI)兩種異構體,主要用作聚氨酯軟質泡沫、塗料、橡膠、纖維、膠粘劑的原料。

MDI是二苯甲烷二異氰酸酯,是一種有機物,是芳烴下游主要產品,廣泛應用於聚氨酯彈性體,製造合成纖維、人造革、無溶劑塗料等聚氨酯材料的生產領域。

(4)tdi可以做現貨期貨嗎擴展閱讀:

甲苯二異氰酸酯容易與包含有活潑氫原子的化合物:胺、水、醇、酸、鹼發生反應,特別是與氫氧化鈉和叔胺發生難以控制反應,並放出大量熱。與水反應生成二氧化碳是聚氨酯泡沫塑料製造過程中的關鍵反應之一,應避免受潮。

用二苯甲烷二異氰酸酯製成的聚氨酯製品由於已經顯示出高的抗撕裂強度,耐低溫柔軟性,低導熱系數等良好的化學穩定性等特點,被廣泛地用於生產聚氨酯合成革,人造革塗層、聚氨酯軟泡、硬質泡沫等,特別用於建築材料。

5. TDI是做啥用的

TDI是英文Turbo Direct Injection的縮寫,意為渦輪增壓直接噴射(柴油發動機)。 為了解決SDI的先天不足,人們在柴油機上加裝了渦輪增壓裝置,使得進氣壓力大大增加,壓縮比一般都到10以上,這樣就可以在轉速很低的情況下達到很大的扭矩,而且由於燃燒更加充分,排放物中的有害顆粒含量也大大降低,TDI技術使燃油經由一個高壓噴射器直接噴射入氣缸,因為活塞頂地造型是一個凹陷式的碗狀設計,燃油會在氣缸內形成一股螺旋狀的混合氣。 大眾集團首創的直噴式渦輪增壓柴油發動機(TDI)技術十分先進,而且採用了多項先進技術,例如泵噴射系統、可調葉片式渦輪增壓器等等都是首次在國產轎車上應用。大眾TDI採用了最新的高壓燃油噴射技術---泵噴射系統。此系統使柴油與空氣混合更充分,燃燒更徹底;同時採用氧化型催化反應器,大大降低了CO、HC、顆粒的排放,其中CO2排放與同排量汽油車比可降低30%。另外,採用EGR系統,大大降低了NOx產生,其排放指標滿足歐3標准。

6. TDI能替代MDI來做固化劑么

可以。但用料不同。

7. MDI TDI 是甲類危險化學品還是乙類危險化學品

毒鼠強等5種禁用劇毒化學品任何人,任何情況下禁止做,不能做,不許做,不許買,不許賣,不許存,不許用 ,否則要觸犯刑法125條第二款. MDI,TDI,三氯氧磷,紅礬鈉等 是其他一般劇毒化學品.按危險化學品管理條例,生產要許可證,使用要備案,規定做,限製做, 限制買,限制賣,限制存,限制用,否則觸犯危險化學品管理條例,要限期整改,拒不整改的要按行政處罰法,罰款. 中華人民共和國最高人民法院祝二軍處長博士"<<關於辦理非法製造、買賣、運輸、儲存毒鼠強等禁用劇毒化學品刑事案件具體應用法律若干問題的解釋>的理解與適用> 道出了立法的本意.但下面公安部門把335種劇毒化學品,如生產大量用的液氯 三氯氧磷 紅礬鈉 TDI等化工原料偶爾觸犯危化管理條例的都往刑法125條第二款套,先來一個取保候審.冤屈,影響生產不說,浪費司法資源呀!!

8. TDi80和MR200加聚醚做成的固化劑,為什麼固化後會很脆,沒有韌性和彈性,請教各位懂的專家解答

下午好,TDI和聚醚都屬於硬段分子結構,如果你實現聚合反應用的是聚酯多元醇就容易出現這種情況和PU清漆一樣,芳香族異氰酸酯本來就要比脂肪族共軛強度更大,你換成THF開環縮聚的聚醚多元醇我想應該會變得柔軟一些。TDI和做列克納膠水的TTI相近固化後除非做中空發泡通常都是缺乏彈性模量的。

9. tdi100與tdi80做出的聚氨酯彈性體在性能上有何不同

tdi100與tdi80做出的聚氨酯彈性體在性能上不同有TDI-100主要應用於高品質聚氨酯彈性體的生產,從一定程序上解決了TDI80/20反應速度過快不易操作的問題,容易製成透明的製品。
TDI全稱Toluene-2,4-diisocyanate;2,4-tolylene diisocyanate是甲苯二異氰酸酯的英文縮寫。
TDI(甲苯二異氰酸酯)是常用的多異氰酸酯的一種,而多異氰酸酯是聚氨酯(PU)材料和重要基礎原料。聚氨酯工業常用的TDI是2,4-TDI和2,6-TDI兩種異構體的混合物,包括3種常用的牌號:TDI-80/20,TDI-100和TDI-65/35。前面的數字表示組成中2,4-TDI的含量。比如TDI-80/20中的80表示其組成為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(約98% ),2,6-TDI的異構體很少。主要用於生產軟質聚氨酯泡沫及聚氨酯彈性體、塗料、膠黏劑等。
TDI在裝修中主要存在於油漆之中,超出標準的游離TDI會對人體造成傷害,主要是致敏和刺激作用,出現眼睛疼痛、流淚、結膜充血、咳嗽、胸悶、氣急、哮喘、紅色丘疹、斑丘疹、接觸性過敏性等症狀。國際上對游離TDI的限制標準是0.5%以下。
甲苯二異氰酸酯為無色或淡黃色有刺激性臭味的透明液體,在紫外線照射下變黃;在合金鋼容器中加熱易聚合;能與羥基化合物中的羥基、水、胺及具有活潑氫的化合物反應生成氨基甲酸酯、脲、氨基脲及雙縮脲等。
