熱解英語怎麼說及英文翻譯
『壹』 專業英語翻譯
Thermogravimetric analysis of rubber and coal TGA diagrams expressed as rates of mass loss from the gasification/combustion of ground SBR, tyre chunks, polystyrene of various degrees of cross-linking, carbon black and coal are shown in Figure 5, at a heating rate of 20Kmin -l. Polystyrene devolatilized entirely at temperatures in the vicinity of 680 K. SBR and tyre chunks showed signs of weight loss at temperatures as low as 550K (15wt% loss). This may possibly be associated with evolution of aliphatic pyrolysates of butadiene. A second peak followed around 700 K (in the range 17- 39wt% loss), presumably corresponding to the lighter pyrolysates of the decomposition of polystyrene (polystyrene decomposes to styrene, 40wt%, and other longer chain pyrolysates37).
圖5顯示的是磨碎的丁苯橡膠、輪胎塊粒、不同程度交聯的聚苯乙烯、炭黑及煤經過氣化燃燒後以失重率來展現的橡膠與煤的熱重分析圖;燃燒是以每分鍾20K的升溫率進行。在溫度接近680K時,聚苯乙烯完全熱解,在溫度550K時,丁苯橡膠和輪胎塊粒出現失重跡象(15%失重率);這可能與丁二烯的脂族熱解產物的演變相關。第二高峰是在700K左右來臨(失重率范圍在17-39%),據推測這是與聚苯乙烯分解後較輕的熱解產物相對應(聚苯乙烯分解為苯乙烯,失重率40%,及其他較長鏈的熱解產物,37%)。
A third strong peak was recorded at or slightly above 800 K (representing 40-50wt% loss). Finally, a weak peak was recorded around 1000K, which accounted for up to 5wt% of the total mass and was attributed to part of the carbon black oxidation. A few per cent of the initial weight remained as a white resie and was classified as ash.
溫度在800K或稍高時記錄了第三強高峰的到來(代表失重率40-50%)。最後,在1000K時記錄了一個弱高峰,其失重率占總質量的5%,屬於部分炭黑氧化所造成。只剩下的白色沉澱物是原重量的幾個百分點,被分類為灰。
In separate runs, pure carbon black burned in the temperature region 780-900 K (see Figure 5). Thus, since the carbon black content of the rubber was determined to be 35wt%, it becomes evident that the third and largest peak, observed at 800K, was e to simultaneous oxidation/gasification of most of the carbon black content (35 - 5 = 30 wt%) and heavy pyrolysates from polystyrene (accounting for 10-20wt%) that has been cross-linked in rubber ring the vulcanization process.
從另外的觀測,純炭黑在780-900K的溫度區域燃燒(參閱圖5)。既然橡膠的炭黑含量是其重量的35%,
很顯然在800K時所觀測到的第三及最大高峰,是歸因於大部分的炭黑含量(35—5=30wt%)以及在硫化過程時橡膠交聯的聚苯乙烯重熱解產物(佔10-20wt%)的同時氧化和氣化。
The possibility of the evolution of the latter components was supported by TGA experiments with home-made 25% cross-linked polystyrene (described in Reference 38). Such particles exhibited two peaks, one at 600 and another at 800K, in contrast to the single peak of uncross-linked polystyrene mentioned above. The second peak of this material overlaps with the largest mass loss peak of the tyres, and also with that of carbon black oxidation. Coal particles of the larger size (180-212#m) exhibited a sharp peak at about 720 K and a wide peak in the range 800-900 K, presumably attributed to the gasification and oxidation of volatiles and char, respectively.
使用自製的25%交聯聚苯乙烯進行熱重試驗的結果支持後者成分演變的可能性(闡述於參考38);該類粒子展現兩個高峰,一個在600K,另一個在800K,與上述非交聯聚苯乙烯的僅一個高峰相比,迥然不同。本材料的第二高峰與輪胎的最大失重高峰以及炭黑的氧化重疊。可能是揮發物的氣化及半焦的氧化原因,較大的煤粒(180-212#m)在720K時展示銳鋒以及溫度在800-900K范圍時展示寬峰。
This behaviour strikingly resembles that recorded in the pyrometric radiation intensity profiles, which will be presented in the following section. Coal particles of the smaller size cut (75-90 #m) sustained a very broad single oxidation peak, 700-900 K, which may be perceived as an indication of, at least partially, overlapping volatile evolution and char oxidation of these smaller particles. The gasification/combustion rates of all materials in the TGA were similar at the heating rates of either 10 or 20 Kmin -] , concted here.
這種特性與將在下節介紹的測高溫輻射的強度譜有驚人的相似之處。較小的煤粒(75-90 #m)持續一個很寬的氧化高峰,700-900K,這種表現的原因可以被認為可能是這些小粒子的揮發物演變和半焦氧化過程重疊所造成,最少是部分原因。本次試驗的所有材料在TGA里執行每分鍾10或20K升溫率時的氣化 / 燃燒率是一樣的。
問題補充:The temperatures at which mass loss occurred changed little, if any, with either the heating rate in the TGA or the particle size in the sample.
However, devolatilization at different temperatures may be expected at the much higher heating rates of the droptube furnace.(緊接著的)注:#m為微米的單位
無論是TGA里的升溫率是多少或是樣品顆粒的大小,當失重發生時的溫度變化不大。
不過,在管式沉降爐里進行更高的升溫率燃燒時,可以預期不同溫度的脫揮發分。
