Description

以丙烷當燃氣用於超合金表面噴塗抗磨塗層之方法 Method for spraying anti-wear coating on surface of superalloy with propane as gas

本發明係與超合金表面噴塗製程有關,特別是指一種以丙烷當燃氣用於超合金表面噴塗抗磨塗層方法。 The invention relates to a superalloy surface spraying process, in particular to a method for spraying anti-wear coating on a superalloy surface with propane as gas.

近幾年國內外業者對於超合金表面的應用能力不斷研發,使其超合金表面之耐壓度及抗磨性提昇許多,使得各種超合金應用能連續發展,相對來說對於物合金表面需要更高抗壓強度及耐磨特性的要求門檻也愈來愈高,例如:應用在各種氣體渦輪引擎及葉片或葉輪方面,而在這幾年用來提昇超合金表面硬度及抗磨度的技術不外乎採以丙烯或丙烷做為噴塗燃氣將其碳化鎢粉末噴塗於超合金表面,藉以形成一抗磨塗層,但丙烯卻因高雄氣爆事件,導致價格快速上漲,更使得供貨量無法穩定,使用丙烯做為噴塗製程的噴塗燃氣,導致受影響工件之噴塗製程效率大幅降低,因此有部份業者開始採用丙烷替代丙烯做為超合金噴塗高性能抗磨耗塗層製程之噴塗燃氣,因丙烷價格相對丙烯價格便宜許多,更可解決供貨不穩定問題。 In recent years, domestic and foreign industry's application of superalloy surface has been continuously researched, which has improved the pressure resistance and wear resistance of superalloy surfaces, which makes the development of various superalloys continuous, relatively speaking, the surface of the alloy needs to be more The requirements for high compressive strength and wear resistance are also increasing. For example, it is applied to various gas turbine engines and blades or impellers. In the past few years, the technology used to improve the surface hardness and wear resistance of superalloys has not been used. Except for propylene or propane as spray gas, its tungsten carbide powder is sprayed on the superalloy surface to form an anti-wear coating, but propylene is rapidly rising due to the Kaohsiung gas explosion event, which makes the supply Unstable, using propylene as a spray process gas for spraying process, resulting in a significant reduction in the efficiency of the spray process of the affected workpiece, so some operators began to use propane instead of propylene as a superalloy spray high-performance anti-wear coating process Gas, because the price of propane is much cheaper than propylene, it can solve the problem of unstable supply.

而採用丙烷做為噴燃氣,卻因內含有乙硫醇及石臘(脛類)成份之臭味劑,在噴塗製程中會使得燃氣噴塗設備中之伺服馬達流量計堵塞,而阻礙噴塗燃氣流通無法量測,造成燃氣噴塗設備當機,嚴重影響抗磨塗層品質及製程穩定度。 The use of propane as the gas for spraying, but because of the odorant containing ethanethiol and paraffin (smoke) components, the servo motor flowmeter in the gas spraying equipment will be blocked during the spraying process, and the spraying is hindered. The gas circulation cannot be measured, causing the gas spraying equipment to crash, which seriously affects the quality of the anti-wear coating and the stability of the process.

且因丙烷燃氣係屬於一種三碳的烷烴,化學式為C3H8,因本身化學性能的關係極易在噴塗過程中因壓力及環境溫差改變時由氣態變回液態,同樣因乙硫醇及石臘(脛類)造成燃氣噴塗設備中之伺服馬達流量計堵塞,而阻礙噴塗燃氣流通無法量測,導致燃氣噴塗設備當機,嚴重影響抗磨塗層品質及製程穩定度。 And because the propane gas belongs to a three-carbon alkane, the chemical formula is C3H8. Because of its chemical properties, it is easy to change from a gaseous state to a liquid state during the spraying process due to pressure and environmental temperature difference, also because of ethanethiol and paraffin. (胫) causes the servo motor flowmeter in the gas spraying equipment to be blocked, which hinders the flow of the sprayed gas and cannot be measured, which causes the gas spraying equipment to crash, which seriously affects the quality of the anti-wear coating and the stability of the process.

以及習知燃氣噴塗設備之噴嘴,請參閱圖1所示,係習知噴嘴結構剖視圖,習知噴嘴1係具有噴嘴入口端2與噴嘴出口端3,噴塗燃氣係由噴嘴入口端1進入,並由噴嘴出口端2噴出進行噴塗,然而該噴嘴出口端3之內部孔徑A係由入口B至出口C皆為一致呈現直線式,因此習知之噴嘴1無法提昇噴塗之流速及流量及送粉背壓,噴塗燃氣之燃燒氣體火焰長度及寬度不足,導致碳化鎢粉末無法完全熔融於火焰內焰中心,進而使得碳化鎢粉末無法緻密均勻地噴塗於該超合金表面,使得抗磨塗層之性能無法達到高性能抗磨塗層之規範特性要求(GE F50TF71規範要求)。 As well as the nozzle of the conventional gas spraying device, please refer to FIG. 1 , which is a cross-sectional view of a conventional nozzle structure. The conventional nozzle 1 has a nozzle inlet end 2 and a nozzle outlet end 3 , and the spray gas is introduced from the nozzle inlet end 1 . And sprayed from the nozzle outlet end 2 for spraying. However, the internal aperture A of the nozzle outlet end 3 is linear from the inlet B to the outlet C. Therefore, the conventional nozzle 1 cannot raise the flow rate and flow rate of the spraying and powder feeding. Back pressure, the length and width of the combustion gas flame of the sprayed gas are insufficient, so that the tungsten carbide powder cannot be completely melted in the flame inner flame center, so that the tungsten carbide powder can not be densely and uniformly sprayed on the superalloy surface, so that the anti-wear coating is Performance does not meet the specification characteristics of high performance anti-wear coatings (GE F50TF71 specification requirements).

是以,如何克服上述以丙烷替代丙烯做為超合金噴塗製程之噴塗燃氣缺點以及噴塗燃氣之燃燒氣體火焰長度及寬度不足等問題,即為本發明首要研發課題。 Therefore, how to overcome the above problems of propane instead of propylene as a super-alloy spraying process, and the shortage of the length and width of the combustion gas flame of the sprayed gas are the primary research and development issues of the present invention.

In addition to making the process more stable, the quality of the high-performance anti-wear coating on the superalloy surface is further improved.

The experimental data conforms to the data reference drawing of the GE F50TF71 specification.

本發明主要係提供一種以丙烷當噴塗燃氣用於超合金表面噴塗抗磨塗層之方法,其關鍵製程中係採用丙烷做為噴塗燃氣,以及含鈷8-18%之碳化鎢做為欲噴塗在超合金k表面之噴塗粉末。 The invention mainly provides a method for spraying an anti-wear coating on a superalloy surface by spraying propane gas, wherein a key process comprises using propane as a spray gas and a cobalt carbide containing 8-18% cobalt as a tungsten carbide. Spray powder to be sprayed on the superalloy k surface.

請參圖2所示,係本發明製程概要示意圖,為使碳化鎢粉末能與丙烷燃氣在噴塗製程時呈現最佳化融合,需先對碳化鎢粉未進行一適當時間及溫度之烘烤程序a(其溫度為50-80度C、時間為5-10小時),且為使被加工之超合金k表面可供碳化鎢粉末完整塗覆,亦需先對超合金k表面做物件前處理程序b,而物件前處理程序b包括利用丙銅先對物件表面清潔,再利用高溫膠帶對超合金進行遮護,最後利用氧化鋁砂對超合金k表面進行噴砂,使超合金k形成一可供噴塗之表面。 Referring to FIG. 2, it is a schematic diagram of the process of the present invention. In order to optimize the fusion of the tungsten carbide powder with the propane gas during the spraying process, the tungsten carbide powder is first baked at an appropriate time and temperature. Procedure a (the temperature is 50-80 degrees C, the time is 5-10 hours), and in order to make the surface of the processed superalloy k available for the complete coating of the tungsten carbide powder, it is also necessary to first make the object on the superalloy k surface. Process b, and the object pre-processing program b includes first cleaning the surface of the object with copper, and then shielding the superalloy with high temperature tape. Finally, the surface of the superalloy k is sandblasted with alumina sand to form a superalloy k. Surface that can be sprayed.

接續,在對碳化鎢粉末進行烘烤程序a及超合金表面做物件前處理程序b後,對存放於一燃氣鋼瓶T內之丙烷燃氣進行第一道過濾程序c,使燃氣鋼瓶T內之髒污雜質過濾去除再進行一隔水氣化程序d,將丙烷燃氣加熱氣化成氣態狀並存放於一儲氣桶T1。 After the baking process a of the tungsten carbide powder and the pre-treatment procedure b of the superalloy surface, the first filtration procedure c is performed on the propane gas stored in a gas cylinder T to make the gas cylinder T The dirty impurities inside are filtered and removed, and then a water vaporization process d is performed, and the propane gas is heated and vaporized into a gaseous state and stored in a gas storage tank T1.

然而就如先前技術中所提及因丙烷燃氣內係含有乙硫醇及石臘(脛類)之臭味劑,故本發明需利用一噴塗燃氣純化過濾控制系統10將丙烷燃氣中之乙硫醇及石臘完全純化及過濾掉,以得到最佳質量之丙烷燃氣,將純化過濾後之丙烷燃氣輸送至一燃氣噴塗設備20進行噴塗。 However, as mentioned in the prior art, since the propane gas contains an odorant of ethanethiol and paraffin, the present invention requires a spray gas purification filter control system 10 to be used in propane gas. The ethanethiol and paraffin are completely purified and filtered to obtain the best quality propane gas, and the purified filtered propane gas is sent to a gas spraying device 20 for spraying.

再者,本發明係利用一加長漸擴型高流速噴嘴系統30連接該燃氣噴塗設備20及碳化鎢粉末,藉由該加長漸擴型高流速噴嘴系統30使得在超合金k表面噴塗程序e中將碳化鎢粉末集中在火焰F內焰中心,達到完全熔融於該超合金k表面形成一抗磨塗層K1,配合圖3所示,係本發明加長漸擴型高流速噴嘴系統所噴出之火焰F示意圖。 Furthermore, the present invention utilizes an elongated diverging high velocity nozzle system 30 to connect the gas spraying apparatus 20 and tungsten carbide powder, and by the elongated diverging high velocity nozzle system 30, the superalloy k surface spraying procedure e The tungsten carbide powder is concentrated in the inner flame center of the flame F, and is completely melted on the surface of the super alloy k to form an anti-wear coating K1. As shown in FIG. 3, it is sprayed by the elongated and high-flow nozzle system of the present invention. Schematic diagram of flame F.

惟,為確保本發明之丙烷燃氣從噴塗製程開始到進行超合金K表面噴塗之過程中一直保持氣態,而不會因為外在溫差或壓力導致丙烷燃氣由氣態變回液態的現象,故本發明係藉由一噴塗燃氣恆溫恆壓防液化控制系統40防止已氣化後之丙烷燃氣由氣態變回液態。 However, in order to ensure that the propane gas of the present invention is kept in a gaseous state from the beginning of the spraying process to the spraying of the superalloy K surface, the propane gas does not change from a gaseous state to a liquid state due to an external temperature difference or pressure, so The invention prevents the gasified propane gas from changing from a gaseous state to a liquid state by a spray gas constant temperature and constant pressure anti-liquefaction control system 40.

進一步說明本發明之噴塗燃氣恆溫恆壓防液化控制系統40主要手段及功能,請配合圖4所示,主要功能係為達到對燃氣鋼瓶T內之丙烷燃氣進行加熱氣化形成氣態狀,並防止丙烷燃氣由氣態再變回液態,而設計此系統主要係因本發明改以丙烷替代丙烯做為噴塗燃氣,而丙烷燃氣是一種三碳的烷烴,化學式為C3H8,亦稱為液化石油氣,同其它烴類一樣,加入充足氧氣(Oxygen)及高壓空氣(Compressed Air)時產生可見的火焰,但因丙烷燃氣本身化學性能的關係極易在噴塗過程中當壓力及環境溫差改變時由氣態變回液態,而丙烷燃氣一旦變成液態將使燃氣噴塗設備20中之伺服馬達流量計21堵塞,而阻礙噴塗燃氣流通無法量測,造成燃氣噴塗設備20當機,導致無法進行最後之噴塗程序e。 Further explaining the main means and functions of the spray gas constant temperature and constant pressure anti-liquefaction control system 40 of the present invention, please refer to FIG. 4, the main function is to achieve gasification of the propane gas in the gas cylinder T by heating and gasification. And to prevent the propane gas from returning from the gaseous state to the liquid state, and the system is mainly designed according to the invention, the propane is replaced by propane as the spray gas, and the propane gas is a three-carbon alkane, the chemical formula is C 3 H 8 Liquefied petroleum gas, also known as other hydrocarbons, produces a visible flame when added with sufficient oxygen (Oxygen) and high pressure air (Compressed Air), but due to the chemical properties of propane gas itself, it is easy to be used during the spraying process. When the pressure and ambient temperature difference change, the gas state changes back to the liquid state, and once the propane gas becomes liquid, the servo motor flow meter 21 in the gas spraying device 20 will be blocked, and the flow of the gas flowing through the gas spraying device cannot be measured, resulting in the gas spraying device. 20 crashes, resulting in the inability to perform the final spray procedure e.

因此本發明之噴塗燃氣恆溫恆壓防液化控制系統40包括:至少一個以上之防液化器41、恆溫裝置42、測溫器43、恆壓裝置44,並依實際數量需求將上述器具設置在該燃氣鋼瓶T、儲氣桶T1及燃氣噴塗設備20上,而噴塗燃氣恆溫恆壓防液化控制系統40中之防液化器41(可為一加熱電毯),利用將防化器41安 裝在每個階段存放丙烷燃氣之燃氣鋼瓶T、儲氣桶T1及燃氣噴塗設備20內,可對丙烷燃氣隨時進行加熱氣化,使丙烷燃氣一直保持氣態。 Therefore, the spray gas constant temperature and constant pressure anti-liquefaction control system 40 of the present invention comprises: at least one anti-liquefaction device 41, a thermostat device 42, a temperature detector 43, a constant pressure device 44, and the above-mentioned instruments are set according to actual quantity requirements. The gas cylinder T, the gas storage tank T1 and the gas spraying equipment 20, and the anti-liquefaction device 41 (which can be a heating blanket) in the spray gas constant temperature and constant pressure anti-liquefaction control system 40, utilizes the anti-chemicalizer 41 amps The gas cylinder T, the gas storage tank T1 and the gas spraying equipment 20 which are installed at each stage for storing propane gas can heat and gasify the propane gas at any time, so that the propane gas is kept in a gaseous state at all times.

另利,利用該測溫器43配合該恆溫裝置42隨時監測溫度變化,而該恆溫裝置42之溫度值係設置50-80度C區間,更準確來說當測溫器43一旦監測到該燃氣鋼瓶T、儲氣桶T1及燃氣噴塗設備20之溫度落差異常,也就是溫度超出50-80度C區間,該恆溫裝置42立即啟動,使器具內溫度得以隨時保持在最佳溫度值(即50-80度C區間),如此一來該該燃氣鋼瓶T、儲氣桶T1及燃氣噴塗設備20內之丙烷燃氣便不會因為在傳遞過程受到溫差的變化由氣態再變回液態,進而堵塞燃氣噴塗設備20中之伺服馬達流量計21,導致噴塗燃氣流通無法量測,造成燃氣噴塗設備20當機之問題現象。 In addition, the temperature detector 43 is used to monitor the temperature change at any time, and the temperature value of the thermostat 42 is set in the range of 50-80 degrees C. More precisely, when the temperature detector 43 detects the combustion The temperature difference between the gas cylinder T, the gas storage tank T1 and the gas spraying equipment 20 is abnormal, that is, the temperature exceeds the range of 50-80 degrees C, and the thermostat 42 is immediately activated, so that the temperature inside the appliance can be maintained at the optimum temperature value at any time ( That is, the interval of 50-80 degrees C), so that the gas cylinder T, the gas storage tank T1 and the propane gas in the gas spraying equipment 20 will not change back from the gaseous state due to the temperature difference during the transfer process. The liquid state, which in turn blocks the servo motor flow meter 21 in the gas spraying device 20, causes the flow of the sprayed gas to be unmeasurable, causing a problem of the gas spraying device 20 being down.

此外,因丙烷燃氣在傳遞過程不僅會因為溫差變化產生由氣態變回液態現象,同樣也會因為壓力變化產生由氣態變回液態的現象,因此為防止經純化過濾後之丙烷燃氣在由噴塗燃氣純化過濾控制系統10傳遞至燃氣噴塗設備20過程中受到外在壓力差的影響,使丙烷燃氣由氣態狀再變回液態,故於該噴塗燃氣純化過濾控制系統10與燃氣噴塗設備20之間加設該恆壓裝置44,藉由該恆壓裝置44使丙烷燃氣在傳遞過程不會受到壓力改變之影響,其中該恆壓裝置44之壓力值以90-120PSI為最佳值,據此利用該噴塗燃氣純化過濾控制系統10可丙烷燃氣不會在該噴塗燃氣純化過濾控制系統10與燃氣噴塗設備20傳遞過程中受到壓力差的影響由氣態變回液態。 In addition, because the propane gas in the transfer process will not only change from the gaseous state to the liquid state due to the change of the temperature difference, but also the phenomenon that the gas state changes back to the liquid state due to the pressure change, so the propane gas is prevented from being purified and filtered. When the spray gas purification filter control system 10 is transferred to the gas spraying device 20, the external pressure difference is affected, and the propane gas is changed from the gaseous state to the liquid state, so the spray gas purification filter control system 10 and the fuel are burned. The constant pressure device 44 is added between the gas spraying devices 20, and the constant pressure device 44 prevents the propane gas from being affected by the pressure change during the transfer process, wherein the pressure value of the constant pressure device 44 is 90-120 PSI. The optimum value, according to which the spray gas purification filter control system 10 can be used, the propane gas is not affected by the pressure difference during the transfer of the spray gas purification filter control system 10 and the gas spraying device 20 from the gaseous state. Liquid.

透過本發明噴塗燃氣恆溫恆壓防液化控制系統40確實可有效解決丙烷燃氣在整個噴塗製程(由燃氣鋼瓶T→儲氣桶T1→燃氣噴塗設備20)因氣態 變回液態之現象,造成燃氣噴塗設備20中之伺服馬達流量計21堵塞,阻礙噴塗燃氣流通無法量測,導致燃氣噴塗設備20當機,嚴重影響塗層品質之問題。 The spraying gas constant temperature and constant pressure anti-liquefaction control system 40 of the present invention can effectively solve the gaseous state of the propane gas in the whole spraying process (from the gas cylinder T→gas storage tank T1→gas spraying equipment 20) The phenomenon of changing back to the liquid state causes the servo motor flow meter 21 in the gas spraying equipment 20 to be blocked, hindering the flow of the sprayed gas and failing to measure, causing the gas spraying equipment 20 to crash, seriously affecting the quality of the coating.

此外,請再配合圖5所示,係本發明噴塗燃氣純化過濾控制系統示意圖,進一步說明本發明噴塗燃氣純化過濾控制系統10主要手段及功能,其噴塗燃氣純化過濾控制系統10包括:一燃氣入口11、一燃氣排放管路110、一燃氣出口12、一排洩口13、一過濾吸附空間14及一氣化空間15,而燃氣排放管路110係連接該燃氣入口11並設置於該過濾吸附空間14下方,而該氣化空間15係設置該過濾空間14上方。 In addition, please refer to FIG. 5, which is a schematic diagram of the spray gas purification filter control system of the present invention, further illustrating the main means and function of the spray gas purification filter control system 10 of the present invention, and the spray gas purification filter control system 10 includes: a gas inlet 11, a gas discharge line 110, a gas outlet 12, a drain port 13, a filter adsorption space 14 and a gasification space 15, and a gas discharge line 110 is connected to the gas inlet 11 And disposed below the filtered adsorption space 14, and the gasification space 15 is disposed above the filtration space 14.

其中,過濾吸附空間14係由至少一層以上之導流過濾層140、一粗網不銹鋼鋼絲絨過濾層141、一細網不銹鋼鋼絲絨過濾層142及一吸附棉過濾層143由下而上依序構成,其中該導流過濾層140可為概呈倒V型吸附板,且該粗網不銹鋼鋼絲絨過濾層141之鋼絲直徑以1mm為最佳值、該細網不銹鋼鋼絲絨過濾層142之鋼絲直徑以0.25mm為最佳值。 The filter adsorption space 14 is composed of at least one layer of the flow guiding filter layer 140, a coarse mesh stainless steel wool wool filter layer 141, a fine mesh stainless steel wool wool filter layer 142 and an adsorbent cotton filter layer 143 from bottom to top. The flow guiding filter layer 140 can be a substantially inverted V-shaped adsorption plate, and the wire diameter of the coarse mesh stainless steel steel wool filter layer 141 is 1 mm, and the wire of the fine mesh stainless steel steel wool filter layer 142 The diameter is preferably 0.25 mm.

該噴塗燃氣純化過濾控制系統10之純化過濾方式,主要係利用該過濾吸附空間14將丙烷燃氣中之石臘M過濾去除,因石臘M本身顆粒大小不一,因此過濾方式係提供丙烷燃氣由燃氣入口11所連接之排放管路110進入該噴塗燃氣純化過濾控制系統10內部底端,並由排放管路110之排放孔1100向上排出進入該過濾吸附空間14開始過濾,首先丙烷燃氣先會經過第一層之導流過濾層140,利用該導流過濾層140以概呈倒V型吸附板之設計,先將丙烷燃氣中最粗顆粒石臘M吸附並過濾去除。 The purification and filtration method of the spray gas purification filter control system 10 mainly uses the filter adsorption space 14 to filter and remove the paraffin M in the propane gas. Since the particle size of the paraffin M itself is different, the filtration method provides propane. The gas is discharged from the exhaust pipe 110 connected to the gas inlet 11 into the bottom end of the spray gas purification filter control system 10, and is discharged upward from the discharge hole 1100 of the discharge pipe 110 into the filter adsorption space 14 to start filtering. The propane gas first passes through the first layer of the flow-through filter layer 140, and the flow-through filter layer 140 is used to design the inverted V-shaped adsorption plate, and the coarsest-grained paraffin M in the propane gas is first adsorbed and filtered. .

雖然藉由第一層導流過濾層140可將丙烷燃氣中大部份且最粗顆粒石臘M先過濾掉,但實際上丙烷燃氣內仍有殘存較細顆粒之石臘M,故該丙烷 燃氣依續進入粗網不銹鋼鋼絲絨過濾層141及細網不銹鋼鋼絲絨過濾層142,將丙烷燃氣中較細顆粒石臘M再次進行過濾去除。 Although most of the coarsest particles of paraffin M are first filtered out by the first layer of the flow-through filter layer 140, in fact, there are still fine particles of paraffin M remaining in the propane gas. The propane The gas continues to enter the coarse mesh stainless steel wool wool filter layer 141 and the fine mesh stainless steel wool wool filter layer 142, and the finer particulate wax wax M in the propane gas is filtered again and removed.

經過第一層之導流過濾層140、粗網不銹鋼鋼絲絨過濾層141及細網不銹鋼鋼絲絨過濾層142過濾後,丙烷燃氣中剩下石臘M顆粒已非常微小,但本發明之噴塗燃氣純化過濾控制系統10主要技術係要完全過濾丙烷燃氣中之石臘M,因此最後再利用吸附棉過濾層143更綿密之細微孔洞設計,將丙烷燃氣中所有石臘M完全過濾去除。 After filtering through the first layer of the flow guiding filter layer 140, the coarse mesh stainless steel wool wool filter layer 141 and the fine mesh stainless steel wool wool filter layer 142, the paraffin M particles remaining in the propane gas are very small, but the spraying of the present invention The main technology of the gas purification filtration control system 10 is to completely filter the paraffin M in the propane gas. Therefore, the fine pores of the adsorption cotton filter layer 143 are finally used to completely remove all the paraffin M in the propane gas. .

據此,丙烷燃氣中之石臘M在經過濾吸附空間14過濾去除後僅剩乙硫醇,而乙硫醇則進入該氣化空間15開如加熱氣化,而該氣化空間15內依序設置一加熱層150、一保溫層151一氣化層152,先利用該加熱層150將乙硫醇加熱氣化後,透過該保溫層151保持溫度再進入該氣化層152。 Accordingly, the paraffin M in the propane gas is filtered and removed by the filtered adsorption space 14 to leave only ethyl mercaptan, and the ethyl mercaptan enters the gasification space 15 to be heated and vaporized, and the gasification space 15 is A heating layer 150, a heat insulating layer 151 and a gasifying layer 152 are sequentially disposed. The heating layer 150 is used to heat and vaporize the ethanethiol, and then the temperature is maintained through the insulating layer 151 to enter the gasifying layer 152.

最後乙硫醇與丙烷燃氣依比重不同的特性,乙硫醇由排洩口13排出,而經純化過濾所得之最佳質化之丙烷燃氣則由燃氣出口12輸出。 Finally, the ethanethiol and the propane gas have different characteristics according to the specific gravity, the ethanethiol is discharged from the discharge port 13, and the optimally purified propane gas obtained by the purification and filtration is output from the gas outlet 12.

據此,透過本發明該噴塗燃氣純化過濾控制系統10確實可有效將丙烷燃氣中臭化劑(含乙硫醇及石臘M)完全純化及過濾掉,解決在噴塗製程時不會因丙烷燃氣仍含有臭化劑(含乙硫醇及石臘M)而沾粘到燃氣噴塗設備20之伺服馬達流量計21而污染塗層及影響噴塗燃氣控制問題。 Accordingly, the spray gas purification filter control system 10 of the present invention can effectively purify and filter out the dissolving agent (containing ethanethiol and paraffin M) in the propane gas, thereby solving the problem in the spraying process. Propane gas still contains a odorant (containing ethanethiol and paraffin M) and sticks to the servo motor flow meter 21 of the gas spraying device 20 to contaminate the coating and affect the control of the spray gas.

本發明經由上述噴塗燃氣純化過濾控制系統10及噴塗燃氣恆溫恆壓防液化控制系統40,將丙烷燃氣中臭化劑(含乙硫醇及石臘)完全純化及過濾,並控制丙烷燃氣在整個噴塗製程傳遞過程中不會因氣態變回液態,因此可確實解決燃氣噴塗設備20中之伺服馬達流量計21因沾粘到臭化劑(含乙硫醇及石臘)而造成堵塞,阻礙噴塗燃氣流通無法量測等問題。 The invention completely purifies and filters the dissolving agent (containing ethanethiol and paraffin) in the propane gas through the above-mentioned spray gas purification filter control system 10 and the spray gas constant temperature and pressure anti-liquefaction control system 40, and controls the propane. The gas does not change back to the liquid state due to the gaseous state during the entire spraying process, so it can be surely solved by the servo motor flow meter 21 in the gas spraying device 20 due to sticking to the odorant (containing ethanethiol and paraffin). Causing blockages, hindering the flow of spray gas and measuring problems.

本發明為進一步提昇物合金K表面之抗磨塗層K1高緻密、高硬度、高延長結合力之功效,該燃氣噴塗設備20連接該加長漸擴型高流速噴嘴系統30,請參閱圖6所示,係本發明加長漸擴型高流速噴塗噴嘴系統剖視示意圖,該加長漸擴型高流速噴塗噴嘴系統30係由一加長型入口端31連接一漸擴型高流速噴嘴出口端32組合而成,其中該加長型入口端31係包括一加長部33,以及一氧氣入口310、一粉末入口311、一丙烷燃氣入口312及一高壓空氣入口313。 The invention further enhances the effect of high-density, high-hardness and high-strength adhesion of the anti-wear coating K1 on the surface of the alloy K. The gas spraying device 20 is connected to the elongated and divergent high-flow nozzle system 30, see FIG. Shown is a schematic cross-sectional view of the extended diverging high velocity spray nozzle system of the present invention. The extended diverging high velocity spray nozzle system 30 is connected by an elongated inlet end 31 to a divergent high flow nozzle outlet end 32 combination. The elongated inlet end 31 includes an elongated portion 33, an oxygen inlet 310, a powder inlet 311, a propane gas inlet 312, and a high pressure air inlet 313.

該丙烷燃氣經由該燃氣噴塗設備20中之伺服馬達流量計21控制輸出量後,再經由丙烷燃氣入口312進入該加長漸擴型高流速噴塗噴嘴系統30內,同時該氧氣、碳化鎢粉末及高壓空氣亦分別藉由氧氣入口310、粉末入口311、及高壓空氣入口313進入該加長漸擴型高流速噴塗噴嘴系統30內,因丙烷燃氣屬於可燃氣體,氧氣屬於助燃氣體,再施以適當燃點使氣體產生燃燒現象形成一火焰F(此處屬先前技術,故請容許本發明人不再贅述)。 The propane gas is controlled by the servo motor flow meter 21 in the gas spraying device 20, and then enters the extended diverging high-rate spray nozzle system 30 via the propane gas inlet 312, and the oxygen, tungsten carbide The powder and the high-pressure air also enter the elongated and divergent high-rate spray nozzle system 30 through the oxygen inlet 310, the powder inlet 311, and the high-pressure air inlet 313, respectively. Since the propane gas belongs to the combustible gas, the oxygen belongs to the combustion-supporting gas, and the application is repeated. The flame is generated by the combustion of the gas by a suitable ignition point (this is a prior art, so the inventors will not repeat them).

而本發明之加長漸擴型高流速噴塗噴嘴系統30之特殊設計處係在於該加長型入口端31延伸設置之加長部33,藉由此加長部33之設計可增加該加長型入口端31之長度,相較傳統之噴嘴1並無本發明之加長部33設計,而就本發明實施例而言,該加長型入口端31長度以介於110-140mm區間為最佳值。 The special design of the elongated diverging high-rate spray nozzle system 30 of the present invention is the extension portion 33 extending from the elongated inlet end 31, whereby the elongated inlet end 31 can be increased by the design of the elongated portion 33. The length, compared to the conventional nozzle 1, does not have the design of the elongated portion 33 of the present invention, and for the embodiment of the present invention, the length of the elongated inlet end 31 is preferably in the range of 110-140 mm.

另一特殊設計係於該漸擴型高流速噴嘴出口端32,由圖6之剖視圖顯示該漸擴型高流速噴嘴出口端32之內部孔徑A1係呈現由入口B1逐漸擴張至出口C1的方式,相較習知之噴嘴1之內部孔徑A由入口B至出口C皆為一致之設計截然不同,而就本發明實施例而言,該漸擴型高流速噴嘴出口端32之開口端角度以介於1.0-3.0度區間為最佳值。 Another special design is at the outlet end 32 of the divergent high flow nozzle. The cross-sectional view of FIG. 6 shows that the internal aperture A1 of the diverging high flow nozzle outlet end 32 is gradually expanded from the inlet B1 to the outlet C1. Compared with the conventional design, the internal aperture A of the nozzle 1 is completely different from the design of the inlet B to the outlet C. For the embodiment of the present invention, the opening end angle of the outlet end 32 of the diverging high-flow nozzle is interposed. The 1.0-3.0 degree interval is the best value.

據此,本發明加長漸擴型高流速噴塗噴嘴系統30係結合加長型入口端31與漸擴型高流速噴嘴出口端32之設計,同時經由本發明實驗測試DOE(Design Of Experiment),調整至最佳參數、水準、調合熱能及動能(反應時間、反應溫度、燃氣火焰速度)的條件下,確實達到以下優點。 Accordingly, the extended diverging high-rate spray nozzle system 30 of the present invention combines the design of the elongated inlet end 31 and the divergent high-flow nozzle outlet end 32, and is adjusted to the DOE (Design Of Experiment) by the present invention. Under the conditions of optimal parameters, level, blending heat energy and kinetic energy (reaction time, reaction temperature, gas flame speed), the following advantages are indeed achieved.

經由該加長漸擴型高流速噴塗噴嘴系統30可提昇丙烷燃氣流速及流量(160-210SCFH)及提高送粉背壓(80-110PSI),增加噴塗燃氣之燃燒氣體火焰長度及寬度,並將碳化鎢粉末完全集中在火焰內焰中心,達到完全融合效果,使得碳化鎢粉末可完整噴塗於該超合金K表面,並形成高性能之抗磨塗層K1,請配合參閱圖7所示,係本發明加長漸擴型高流速噴塗噴嘴系統實驗測試數據參考圖。 Through the extended diverging high-flow spray nozzle system 30, the propane gas flow rate and flow rate (160-210 SCFH) and the feed back pressure (80-110 PSI) can be increased, and the length and width of the combustion gas flame of the sprayed gas can be increased, and The tungsten carbide powder is completely concentrated in the center of the flame inner flame to achieve a complete fusion effect, so that the tungsten carbide powder can be completely sprayed on the surface of the super alloy K, and a high-performance anti-wear coating K1 is formed, as shown in FIG. The invention test data reference drawing of the extended diverging high-rate spray nozzle system of the present invention.

Because the temperature difference or pressure difference changes from the gaseous state to the liquid state, The servo motor flow meter 21 in the gas-fired spraying device 20 is blocked, hindering the flow of the sprayed gas and cannot be measured, resulting in a problem of the gas-spraying equipment 20 being down, further improving the high-performance anti-wear coating K1 quality.

第3點、透過本發明加長漸擴型高流速噴塗噴嘴系統30確實可增加丙烷燃氣在整個噴塗製程中之流速及流量(160-210SCFH),及增加送粉背壓(80-110PSI),並提高噴塗燃氣之燃燒氣體火焰長度及寬度,將碳化鎢粉末得以完全集中在火焰內焰中心,達到完全融合效果,進而使得碳化鎢粉末可完整噴塗於該超合金K表面,形成高性能抗壓強度及耐磨之抗磨塗層K1。 At the third point, the elongated and high-flow spray nozzle system 30 of the present invention can increase the flow rate and flow rate (160-210 SCFH) of the propane gas throughout the spraying process, and increase the powder back pressure (80-110 PSI).
