Description

纖維預氧化設備Fiber pre-oxidation equipment

本發明係與碳纖維之預氧化技術有關，主要揭露一種有助於提升碳纖維性能的纖維預氧化設備。The invention relates to the pre-oxidation technology of carbon fibers, and mainly discloses a fiber pre-oxidation device that helps to improve the performance of carbon fibers.

碳纖維是有機纖維經一系列熱處理後轉化而成的含碳量在90%以上的新型碳材料，其具有高比強度、高比模量、高導電性和導熱性、低熱膨脹係數、低密度、耐高溫、耐疲勞、抗蠕變、自潤滑等一系列的優異性能，是一種理想的功能材料和結構材料，廣泛應用於航太、民用航空及運輸等領域，並具有廣闊的應用前景。Carbon fiber is a new type of carbon material with a carbon content of more than 90% converted from organic fibers after a series of heat treatments. It has high specific strength, high specific modulus, high electrical and thermal conductivity, low thermal expansion coefficient, low density, A series of excellent properties such as high temperature resistance, fatigue resistance, creep resistance, and self-lubrication. It is an ideal functional material and structural material. It is widely used in aerospace, civil aviation and transportation, and has broad application prospects.

聚丙烯腈（polyacrylonitrile，PAN)作為原絲的碳纖維製備工藝過程包括聚合、紡絲、預氧化和碳化，其中預氧化過程是碳纖維製備過程中結構轉變的關鍵階段，也是熱處理過程中最耗時的階段，其目的是使聚丙烯腈的線型大分子鏈轉化為具耐熱結構的氧化纖維，使其在後續的碳化時不熔不燃，而能夠保持纖維形態。Polyacrylonitrile (PAN) as raw fiber carbon fiber preparation process includes polymerization, spinning, pre-oxidation, and carbonization. The pre-oxidation process is the key stage of structural transformation in the preparation of carbon fibers, and it is also the most time-consuming process in heat treatment At the stage, the purpose is to transform the linear macromolecular chain of polyacrylonitrile into oxidized fiber with heat-resistant structure, so that it will not melt and burn during subsequent carbonization, and can maintain the fiber morphology.

預氧化過程中原絲的結構轉變在很大程度上決定著碳纖維的結構和性能，在工業化生產中，多係採用梯度升溫的預氧化方式，在此過程中合適的溫度梯度範圍是必要的，起始溫度如果太低，對預氧化過程沒有貢獻，耗費時間增加成本，但起始溫度太高，劇烈的反應放熱會使沒有耐熱能力的PAN大分子鏈熔斷；另外，終止溫度如果太高，集中放熱會破壞預氧絲的結構，並且造成過度預氧化，不利於製備高強度碳纖維，但終止溫度太低，又可能使原絲得不到充分的預氧化。The structural transformation of the precursor fiber during the pre-oxidation process largely determines the structure and performance of the carbon fiber. In industrial production, most systems use a pre-oxidation method with gradient heating. In this process, a suitable temperature gradient range is necessary. If the starting temperature is too low, it does not contribute to the pre-oxidation process and takes time and costs, but the starting temperature is too high, and the severe reaction exotherm will cause the PAN macromolecular chain without heat resistance to fuse; in addition, if the ending temperature is too high, the concentration Exothermic heat will destroy the structure of pre-oxygenated filaments and cause excessive pre-oxidation, which is not conducive to the preparation of high-strength carbon fibers, but the termination temperature is too low, and the pre-filament may not be fully pre-oxidized.

再者，以加熱的方式進行預氧化反應時，隨著預氧化反應的進行，由於熱是由原絲的外層往內層傳遞，因此會先在原絲的外層形成了緻密梯形結構的氧化層(皮部)，這反而阻礙了氧向原絲內層的芯部擴散，造成如第1圖所示之一氧化纖維10當中之一纖維11產生氧化之一氧化層111(皮部)和尚未氧化之一芯部112明顯差異的一皮芯結構，該氧化層111與該芯部112之間存在一皮芯界面113。該皮芯結構的檢驗係利用掃描式電子顯微鏡(SEM，Scanning Electron Microscope)拍攝實體影像圖以觀測該氧化纖維之斷面並分別計算該氧化層的斷面面積與該芯部的斷面面積以及該氧化纖維之斷面面積，該皮芯結構之程度鑑定法為芯部比率(%)等於該芯部的斷面面積除以該氧化層的斷面面積與該芯部的斷面面積之和，亦即芯部比率(%)等於該芯部的斷面面積除以該氧化纖維之斷面面積。另外，該氧化纖維10及其所製成之碳纖維的物性，例如拉伸強度及拉伸模數，還取決於該氧化纖維10或氧化層111之氧化程度及環化程度；該氧化纖維10或氧化層111之氧化程度及環化程度愈高則該氧化纖維10所製成的碳纖維之拉伸強度及拉伸模數也愈高。該氧化層111呈氧化狀態所以結構緻密並導致所製成的碳纖維之高拉伸強度及高拉伸模數，該芯部112呈氧化不完全或未氧化狀態所以結構鬆散並導致所製成的碳纖維之低拉伸強度及低拉伸模數，因此該氧化層111與該芯部112的氧化程度不一致所導致之該皮芯結構即是導致碳纖維抗拉強度降低的主要原因之一。因此，在預氧化反應過程中如何縮短預氧化時間，以及如何提高預氧化程度同時降低甚至消除皮芯結構，對碳纖維生產成本的降低以及性能(拉伸強度及拉伸模數)的提高具有十分重要的意義。Furthermore, when the pre-oxidation reaction is carried out by heating, as the pre-oxidation reaction proceeds, since the heat is transferred from the outer layer of the precursor to the inner layer, an oxide layer with a dense trapezoidal structure is first formed on the outer layer of the precursor ( Leather part), which instead hinders the diffusion of oxygen to the core of the inner layer of the raw silk, causing one of the fibers 11 in one of the oxidized fibers 10 as shown in FIG. 1 to produce an oxidized oxide layer 111 (skin part) and A core-core structure of a core portion 112 is obviously different. A skin-core interface 113 exists between the oxide layer 111 and the core portion 112. The inspection of the sheath-core structure uses a scanning electron microscope (SEM) to take a solid image to observe the cross-section of the oxidized fiber and calculate the cross-sectional area of the oxide layer and the cross-sectional area of the core and The cross-sectional area of the oxidized fiber and the degree of the sheath-core structure are determined by the core ratio (%) equal to the cross-sectional area of the core divided by the sum of the cross-sectional area of the oxide layer and the cross-sectional area of the core. That is, the core ratio (%) is equal to the cross-sectional area of the core divided by the cross-sectional area of the oxidized fiber. In addition, the physical properties of the oxidized fiber 10 and the carbon fiber made by it, such as tensile strength and tensile modulus, also depend on the degree of oxidation and cyclization of the oxidized fiber 10 or the oxide layer 111; the oxidized fiber 10 or The higher the degree of oxidation and cyclization of the oxide layer 111, the higher the tensile strength and tensile modulus of the carbon fiber made from the oxidized fiber 10. The oxide layer 111 is in an oxidized state, so the structure is dense and leads to high tensile strength and high tensile modulus of the manufactured carbon fiber. The core 112 is in an incompletely oxidized or unoxidized state, so the structure is loose and results in The carbon fiber has low tensile strength and low tensile modulus. Therefore, the skin-core structure caused by the inconsistent oxidation between the oxide layer 111 and the core portion 112 is one of the main reasons for the reduction of the tensile strength of the carbon fiber. Therefore, how to shorten the pre-oxidation time during the pre-oxidation reaction, and how to increase the degree of pre-oxidation while reducing or even eliminating the skin-core structure, has a significant impact on the reduction of carbon fiber production costs and the improvement of properties (tensile strength and tensile modulus). Significance.

In addition, the fiber yarn bundle 20 can continuously receive the microwave focusing treatment of the microwave processing unit 40 in the furnace body 33 in a stacking manner at a speed of 1 to 40 minutes through the furnace body 33 to become the oxidized fiber yarn bundle 20A. For example, the fiber yarn bundle 20 enters the furnace body 33 at the front end of the furnace body 33 and is transferred to the rear end of the furnace body 33, and then is transferred from the rear end of the furnace body 33 to the front end of the furnace body 33. Then, it is transferred from the front end of the furnace body 33 to the rear end of the furnace body 33 again. In this way, the winding is repeated until it is transferred from the rear end of the furnace body 33 as the oxidized fiber yarn bundle 20A as required. . The use of the stacked winding method can effectively shorten the required length of the furnace body 33.

據以，可在該傳送單元30之運作下，帶動該纖維紗束20依照預先設定的速度通過該微波處理單元40之作業區域，在該纖維紗束20通過該微波處理單元40作業區域之過程中，利用微波聚焦對連續通過該爐體33的該纖維紗束20施以超高速預氧化處理，將該纖維紗束20加工成為該氧化纖維紗束20A。該纖維紗束20係由該纖維或複數個該纖維集結成束所構成，該氧化纖維紗束20A係由該氧化纖維21或複數個該氧化纖維21集結成束所構成，運用本發明纖維預氧化設備，係將該纖維紗束20之該纖維預氧化為該氧化纖維21。According to this, under the operation of the transmission unit 30, the fiber yarn bundle 20 can be driven through the working area of the microwave processing unit 40 at a preset speed, and the process of the fiber yarn bundle 20 passing through the working area of the microwave processing unit 40 can be driven. In the process, the fiber yarn bundle 20 passing through the furnace body 33 is subjected to ultra-high-speed pre-oxidation treatment by microwave focusing, and the fiber yarn bundle 20 is processed into the oxidized fiber yarn bundle 20A. The fiber yarn bundle 20 is composed of the fiber or a plurality of the fibers assembled into a bundle, and the oxidized fiber yarn bundle 20A is composed of the oxidized fiber 21 or a plurality of the oxidized fibers 21 assembled into a bundle. The oxidizing device pre-oxidizes the fibers of the fiber bundle 20 into the oxidized fibers 21.

請同時配合參照第5圖所示，分別實施以無微波、微波功率12kW/m 2、微波功率16 kW/m 2、微波功率20 kW/m 2、微波功率24 kW/m 2之微波聚焦處理於該纖維紗束20，可確實得到以微波功率24 kW/m 2之微波聚焦處理於該纖維紗束20經過10分鐘後，即可讓該氧化纖維紗束20A當中之該氧化纖維21的氧化程度達到100%，與該纖維紗束20相對應地，該氧化纖維紗束20A由單根該氧化纖維21或複數個該氧化纖維21集結成束所構成。同樣地，以微波功率20 kW/m 2之微波聚焦處理於該纖維紗束20經過15分鐘後，即可讓該氧化纖維紗束20A當中之該氧化纖維21的氧化程度達到100%；以微波功率16 kW/m 2之微波聚焦處理於該纖維紗束20經過25分鐘後，即可讓該氧化纖維紗束20A當中之該氧化纖維21的氧化程度達到100%。而即使僅以微波功率12 kW/m 2之微波聚焦處理於該纖維紗束20經過40分鐘後，即使無法讓該氧化纖維紗束20A當中之該氧化纖維21的氧化程度達到100%，但也可使該氧化纖維21的氧化程度達到89%。而若僅以傳統加熱製程而以270℃對該纖維紗束20加熱經過40分鐘的無微波製程，則該氧化纖維21的氧化程度最多只達到70%。因此，運用本發明所提出之施以微波製程與傳統加熱製程相比，本發明能有效地提高該氧化纖維21的氧化程度且縮短製程時間，尤其以微波功率24 kW/m 2之微波聚焦處理於該纖維紗束20進行10分鐘以達到100%氧化程度的該氧化纖維21，為進行氧化階段的最佳製程條件。 Please also refer to Figure 5 to implement microwave focusing processing with no microwave, microwave power 12kW / m 2 , microwave power 16 kW / m 2 , microwave power 20 kW / m 2 , and microwave power 24 kW / m 2 In the fiber bundle 20, a microwave focusing treatment with a microwave power of 24 kW / m 2 can be surely obtained. After 10 minutes of passing through the fiber bundle 20, the oxidized fiber 21 in the oxidized fiber bundle 20A can be oxidized. The degree reaches 100%. Corresponding to the fiber yarn bundle 20, the oxidized fiber yarn bundle 20A is composed of a single oxidized fiber 21 or a plurality of oxidized fibers 21 gathered into a bundle. Similarly, after the microwave fiber treatment with microwave power of 20 kW / m 2 is focused on the fiber yarn bundle 20 for 15 minutes, the oxidation degree of the oxidized fiber 21 in the oxidized fiber yarn bundle 20A can reach 100%; After the microwave focusing treatment with a power of 16 kW / m 2 is applied to the fiber bundle 20 for 25 minutes, the oxidation degree of the oxidized fiber 21 in the oxidized fiber bundle 20A can reach 100%. And even if only the microwave focusing treatment with a microwave power of 12 kW / m 2 is applied to the fiber bundle 20 after 40 minutes, even if the oxidized fiber 21 in the oxidized fiber bundle 20A cannot be oxidized to 100%, but The degree of oxidation of the oxidized fiber 21 can be 89%. If only the traditional heating process is used to heat the fiber yarn bundle 20 at 270 ° C for 40 minutes without a microwave process, the oxidation degree of the oxidized fiber 21 is only 70% at most. Therefore, using the microwave process provided by the present invention compared with the traditional heating process, the present invention can effectively increase the oxidation degree of the oxidized fiber 21 and shorten the process time, especially the microwave focusing treatment with a microwave power of 24 kW / m 2 The oxidized fiber 21 is subjected to the fiber yarn bundle 20 for 10 minutes to reach 100% oxidation degree, which is the optimal process condition for the oxidation stage.

請同時配合參照第6圖所示，以微波功率24 kW/m 2之微波聚焦處理於該纖維紗束20，分別處理2分鐘、4分鐘、5分鐘、10分鐘及15分鐘並檢驗所形成之該氧化纖維21的環化程度，該氧化纖維21經過5分鐘後之環化程度即達100%，因此環化程度達100%的所需時間5分鐘少於氧化程度所需的時間10分鐘。請同時配合參照第7圖、第8圖及第9圖所示，分別以24 kW/m 2之微波聚焦處理於該纖維紗束20分別進行5分鐘、10分鐘及15分鐘所製造而成之該氧化纖維紗束20A當中的該氧化纖維21的斷面以掃描式電子顯微鏡(SEM，Scanning Electron Microscope)拍攝實體影像圖，發現該氧化層211佔該氧化纖維21之99.0%以上或該氧化層211的斷面面積佔該氧化纖維21之斷面面積係為99.0%以上，且並無明顯之皮芯結構。 At the same time, please refer to Figure 6 to focus the fiber yarn bundle 20 with microwave power of 24 kW / m 2 and process it for 2 minutes, 4 minutes, 5 minutes, 10 minutes, and 15 minutes, and check the formation. The degree of cyclization of the oxidized fiber 21, the degree of cyclization of the oxidized fiber 21 after 5 minutes reaches 100%, so the time required for the degree of cyclization to reach 100% 5 minutes is less than the time required for the degree of oxidation 10 minutes. Please refer to Fig. 7, Fig. 8 and Fig. 9 at the same time. Manufactured by microwave focusing treatment of 24 kW / m 2 on the fiber bundle 20 for 5 minutes, 10 minutes, and 15 minutes, respectively. A scanning electron microscope (SEM) was used to take a solid image of the oxidized fiber 21 in the cross-section of the oxidized fiber yarn bundle 20A. It was found that the oxidized layer 211 accounted for more than 99.0% of the oxidized fiber 21 or the oxidized layer. The cross-sectional area of 211 accounts for 99.0% or more of the cross-sectional area of the oxidized fiber 21, and there is no obvious skin-core structure.

請同時配合參照表一及表二所示，表一為以電熱管加熱方式的傳統製程及使用本發明纖維預氧化設備之氧化纖維製造方法之微波製程，測得該纖維紗束20、該氧化纖維紗束20A及其後續碳化製成之碳纖維紗束的拉伸強度比較表；表二為以電熱管加熱方式的傳統製程及使用本發明纖維預氧化設備之氧化纖維製造方法之微波製程，測得該纖維紗束20、該氧化纖維紗束20A及其後續碳化製成之碳纖維紗束的拉伸模數比較表。前述以電熱管加熱方式的傳統製程，其製程條件為該爐體溫度270℃，處理時間為40分鐘，所得出之物性結果列為『比較例一』；前述本發明的微波製程，其製程條件為該爐體的溫度220℃，微波頻率2450 MHz，微波功率24 kW/m 2，處理時間為10分鐘，所得出之物性結果列為『實施例一』。於比較例一及實施例一中之該纖維紗束20係使用聚丙烯腈所製成。 Please refer to Tables 1 and 2 at the same time. Table 1 is the traditional process of heating by electric heating tube and the microwave process of the oxidized fiber manufacturing method using the fiber pre-oxidation device of the present invention. The fiber bundle 20 and the oxidation were measured. Comparison table of tensile strength of fiber tow 20A and carbon fiber tow made from subsequent carbonization; Table 2 shows the traditional process of electric heating tube heating and the microwave process of the oxidized fiber manufacturing method using the fiber pre-oxidation device of the present invention.

The physical property results obtained are listed in "Example 1". The fiber bundle 20 in Comparative Example 1 and Example 1 was made of polyacrylonitrile.

表一： 拉伸強度(MPa) 纖維紗束 氧化纖維紗束 碳纖維紗束 比較例一 865 221 2824 實施例一 865 164 3675 從表一中顯示實施例一之微波製程所製成之氧化纖維紗束，其最終碳化後之碳纖維紗束的拉伸強度是比較例一的1.3倍(3675除以2824)，亦即拉伸強度提高30%。微波製程因能讓PAN氧化更為完全，所以微波製程的該氧化纖維紗束強度略低於傳統電熱管製程的該氧化纖維紗束強度，此為本發明的微波製程更能夠讓該纖維紗束提高氧化程度之另一證據。 Table I: Tensile strength (MPa) Fiber yarn bundle Oxidized fiber yarn bundle Carbon fiber yarn bundle Comparative example one 865 221 2824 Example one 865 164 3675 Table 1 shows that the tensile strength of the oxidized fiber yarn bundle made by the microwave process of Example 1 after final carbonization is 1.3 times that of Comparative Example 1 (3675 divided by 2824), that is, tensile Increased strength by 30%. Because the microwave process can make the PAN oxidation more complete, the strength of the oxidized fiber yarn bundle in the microwave process is slightly lower than the strength of the oxidized fiber yarn bundle in the traditional electric heating control process. Another evidence to increase the extent of oxidation.

表二： 拉伸模數(GPa) 纖維紗束 氧化纖維紗束 碳纖維紗束 比較例一 8.82 6.03 194.4 實施例一 8.82 6.92 227.1 從表二中顯示實施例一之微波製程所製成之氧化纖維紗束，其最終碳化後之碳纖維紗束的拉伸模數是比較例一的1.17倍(227.1除以194.4)，亦即拉伸模數提高17%。 Table II: Tensile modulus (GPa) Fiber yarn bundle Oxidized fiber yarn bundle Carbon fiber yarn bundle Comparative example one 8.82 6.03 194.4 Example one 8.82 6.92 227.1 Table 2 shows that the tensile modulus of the oxidized fiber yarn bundle made by the microwave process of Example 1 after final carbonization is 1.17 times (227.1 divided by 194.4) of the first carbonized yarn bundle, that is, the tensile modulus Increase in elongation modulus by 17%.

至此，本發明與傳統加熱製程作用於該纖維紗束之該氧化纖維紗束相較，運用本發明能將傳統加熱製程所需的40分鐘縮短為10分鐘，因此製程效率提高3倍，節省了製程的時間；與傳統加熱製程相較，本發明亦將碳纖維紗束的拉伸強度提高30%及拉伸模數提高17%；與傳統加熱製程相較，本發明亦將該氧化纖維紗束20A當中的該氧化纖維21的該氧化層211的斷面面積佔該氧化纖維21之斷面面積係為99.0%以上，使其無明顯之皮芯結構，使得該氧化纖維紗束20A的斷面更趨向均勻一致，故能將碳纖維紗束的拉伸強度及拉伸模數提高。故運用本發明能夠以相對更為積極、可靠之手段提升碳纖維性能。So far, compared with the oxidized fiber yarn bundle which is applied to the fiber yarn bundle by the traditional heating process, the present invention can shorten the 40 minutes required by the traditional heating process to 10 minutes, so the process efficiency is increased by 3 times and saved. Compared with the traditional heating process, the present invention also increases the tensile strength of the carbon fiber yarn bundle by 30% and the tensile modulus by 17%. Compared with the traditional heating process, the present invention also increases the oxidized fiber yarn bundle. The cross-sectional area of the oxide layer 211 of the oxidized fiber 21 in 20A accounts for 99.0% or more of the cross-sectional area of the oxidized fiber 21, so that it has no obvious core-core structure, so that the cross-section of the oxidized fiber yarn bundle 20A It tends to be more uniform, so it can increase the tensile strength and modulus of carbon fiber yarn bundles. Therefore, the application of the present invention can improve the performance of carbon fibers in a relatively more active and reliable way.

運用本發明於實施時，係以24 kW/m 2之微波聚焦處理於該些纖維紗束5~10分鐘之實施樣態呈現為佳。是以本發明可適用於該纖維紗束20通過該爐體33後不經該收卷機組32捲取而是接續碳化製程以連續生產方式生產碳纖維紗束，或適用於成捲之該纖維紗束20以該供料機組31捲出並以該收卷機組32捲取之生產方式。 In the implementation of the present invention, it is better to perform a microwave focusing treatment of 24 kW / m 2 on the fiber yarn bundles for 5 to 10 minutes. Therefore, the present invention is applicable to the continuous production of carbon fiber yarn bundles after the fiber yarn bundles 20 pass through the furnace body 33 without being taken up by the winder unit 32, and then continuous carbonization process, or is applicable to the fiber yarns rolled into rolls. The production mode of the bundle 20 is taken up by the feeding unit 31 and taken up by the winding unit 32.

請再度參照第5圖，如前所述以微波功率12 kW/m 2之微波聚焦處理於220℃對該纖維紗束20經過40分鐘後，該氧化纖維21的氧化程度達到89%；而以傳統加熱製程而以270℃對該纖維紗束20加熱經過40分鐘的無微波製程，則該氧化纖維21的氧化程度達到70%。因此本發明相較於傳統加熱製程而言，能夠以較低的溫度便可達到更高的氧化程度，故可避免浪費熱能。 Please refer to FIG. 5 again. As described above, after the microwave fiber treatment with microwave power of 12 kW / m 2 is performed at 220 ° C for 40 minutes, the oxidation degree of the oxidized fiber 21 reaches 89%.
