噴絲板是紡絲機的重要部件之一，它的作用是將黏流態(tài)的高聚物熔體或溶液，通過微孔轉(zhuǎn)變成有特定截面狀的細流，經(jīng)過凝固介質(zhì)或凝固浴固化而形成絲條。

Spinneret is one of the most important parts of spinning machine. Its function is to change the viscous polymer melt or solution into a specific cross-section flow through micropores, and then solidify in the coagulation medium or coagulation bath to form filaments.

在紡絲過程中噴絲板會被機械雜質(zhì)、碳纖、凝膠等堵塞噴絲孔，當噴絲孔部分堵塞時，在噴絲頭/板外表面會有紡絲溶液漫流，從而造成原絲纖度不勻和產(chǎn)生絲細、絲毛等問題。而當噴絲孔完全堵塞時，則會大大提高纖維的斷頭率，對纖維品質(zhì)有極大的影響，因此必須定期對噴絲板進行清洗。

In spinning process, spinneret will be blocked by mechanical impurities, carbon fiber, gel and so on. When the spinneret is partially blocked, the spinning solution will overflow on the outer surface of spinneret / plate, resulting in uneven yarn size and thin silk and wool. When the spinneret hole is completely blocked, the fiber breakage rate will be greatly improved, which has a great impact on the fiber quality. Therefore, the spinneret must be cleaned regularly.

噴絲板超聲波清洗機

傳統(tǒng)的噴絲板清洗方法如化學、物理或機械會使噴絲孔磨損以致出現(xiàn)侵蝕、微裂、孔徑不規(guī)則等問題，因而要選用清洗效果好且不會對噴絲孔造成損傷的清洗方式，為解決噴絲孔堵塞及清洗工藝會對噴絲孔造成損傷的問題，現(xiàn)在很多工廠采用超聲波清洗機來清洗噴絲板。

Traditional spinneret cleaning methods, such as chemical, physical or mechanical, will make the spinneret hole wear and tear, resulting in erosion, microcracking, irregular aperture and other problems. Therefore, it is necessary to choose the cleaning method with good cleaning effect and no damage to the spinneret hole. In order to solve the problem that the spinneret hole is blocked and the cleaning process will cause damage to the spinneret hole, now many factories use ultrasonic cleaning machine to clean the spinneret Silk board.

超聲波清洗是目前工業(yè)上應(yīng)用廣泛且效果好的一種清洗方式，其工作原理是超聲波在清洗液傳播時，清洗液中的微小氣泡在聲場的作用下產(chǎn)生振動，當聲壓達到一定值后，氣泡會迅速增大，然后閉合瞬間爆破產(chǎn)生可達到上千個大氣壓的沖擊波，沖擊波減小了污漬與被清洗工件的粘著力，可以破壞不溶性污漬而使它們分散在清洗液體中，從而達到清洗的目的。雖然氣泡的破裂能量很高，但是因每個氣泡的體積非常微小，對于工件來說不會產(chǎn)生機械破壞和明顯的溫升。

Ultrasonic cleaning is a widely used and effective cleaning method in industry. Its working principle is that when the ultrasonic wave propagates in the cleaning solution, the tiny bubbles in the cleaning solution will vibrate under the action of the sound field. When the sound pressure reaches a certain value, the bubbles will increase rapidly, and then close and explode instantly to produce shock wave which can reach thousands of atmospheres. The shock wave reduces the dirt and dust The adhesive force of the cleaned workpiece can destroy the insoluble stains and disperse them in the cleaning liquid, so as to achieve the purpose of cleaning. Although the bubble rupture energy is very high, but because the volume of each bubble is very small, there will be no mechanical damage and obvious temperature rise for the workpiece.

在清洗液中由于空化效應(yīng)產(chǎn)生的氣泡數(shù)量眾多且無處不在，因此對于工件的清洗可以非常徹底，即使是形狀復(fù)雜的工件內(nèi)部，只要能夠接觸到清洗液，就可以得到徹底的清洗。所以只要將噴絲頭/板浸入清洗液中，其各個部位都可以得到充分的清洗，包括深孔、狹縫和凹槽。

In the cleaning solution, due to the cavitation effect, the number of bubbles is numerous and everywhere, so the cleaning of the workpiece can be very thorough, even the inside of the workpiece with complex shape, as long as it can contact with the cleaning solution, it can be thoroughly cleaned. Therefore, as long as the spinneret / plate is immersed in the cleaning solution, all parts of the spinneret / plate can be fully cleaned, including deep holes, slits and grooves.

超聲波清洗噴絲板與其他清洗方法相比具有清洗效果好、用時短、節(jié)省成本、操作方便等優(yōu)勢，因而采用超聲波清洗技術(shù)清洗噴絲板是理想的清洗方法。隨著紡織行業(yè)的發(fā)展，采用超聲波清洗噴絲板的企業(yè)也會越來越多，超聲波清洗機在紡織業(yè)將會得到更多的應(yīng)用。

Compared with other cleaning methods, ultrasonic cleaning of spinneret has the advantages of good cleaning effect, short time, cost saving and convenient operation. Therefore, ultrasonic cleaning technology is the most ideal cleaning method for spinneret. With the development of textile industry, there will be more and more enterprises using ultrasonic cleaning spinneret, and ultrasonic cleaning machine will get more application in textile industry.
