全自動超聲波清洗機(jī)技術(shù)應(yīng)用于涂裝前處理的優(yōu)點(diǎn)有哪些

全自動超聲波清洗機(jī)是超聲波清洗機(jī)的一個分支,可用于金屬表面的磷化處理的前處理。所謂磷化,是指用含有磷酸二氫鈉的酸性溶液處理后,在金屬工件表面生成穩(wěn)定的不溶性磷化膜的方法,所得膜稱為磷化膜。磷化膜的主要目的是增加膜層的附著力,提高涂層的耐蝕性。如果采用傳統(tǒng)工藝對工件進(jìn)行酸處理,會造成嚴(yán)重的環(huán)境污染和惡劣的工作環(huán)境。同時,缺點(diǎn)是結(jié)構(gòu)復(fù)雜的零件酸洗除銹后的殘酸難以清洗。工件噴涂一段時間后,沿縫隙發(fā)生腐蝕,損壞涂層表面,嚴(yán)重影響產(chǎn)品外觀和內(nèi)部質(zhì)量。所以,改進(jìn)后的工藝是脫脂、水洗、超聲波除銹、水洗、表調(diào)、磷化、超聲波漂洗、烘干。工藝增加了兩臺超聲波清洗設(shè)備,由鹽酸除銹改為以磷酸為介質(zhì)的超聲波除銹,烘干前的水洗改為超聲波漂洗。
Automatic ultrasonic cleaning machine is a branch of ultrasonic cleaning machine, which can be used for pretreatment of phosphating treatment of metal surface. The so-called phosphating refers to the method of forming a stable insoluble phosphating film on the surface of metal workpieces after treatment with an acidic solution containing sodium dihydrogen phosphate. The resulting film is called phosphating film. The main purpose of phosphating film is to increase the adhesion of the film and improve the corrosion resistance of the coating. If the traditional process is used to treat the workpiece with acid, it will cause serious environmental pollution and bad working environment. At the same time, the disadvantage is that it is difficult to clean the residual acid after pickling and derusting the parts with complex structure. After the workpiece is sprayed for a period of time, corrosion occurs along the gap, damaging the coating surface and seriously affecting the appearance and internal quality of the product. Therefore, the improved process is degreasing, water washing, ultrasonic derusting, water washing, surface conditioning, phosphating, ultrasonic rinsing and drying. Two sets of ultrasonic cleaning equipment are added to the process. The rust removal by hydrochloric acid is changed to ultrasonic rust removal by phosphoric acid as the medium, and the water washing before drying is changed to ultrasonic rinsing.
全自動超聲波清洗機(jī)技術(shù)應(yīng)用于涂裝前處理,具有以下優(yōu)點(diǎn):,超聲波清潔工件表面將達(dá)到非常均勻和清潔的效果。利用超聲波清洗機(jī)的工作原理,可使清洗液中的氣泡均勻破碎,使清洗均勻。其次,它不會損壞高精度的表面。如采用水基工業(yè)清洗劑代替?zhèn)鹘y(tǒng)的強(qiáng)酸強(qiáng)堿,避免了強(qiáng)酸強(qiáng)堿和有機(jī)溶劑對環(huán)境的污染,符合環(huán)保要求。超聲波清洗還可以有效減少有毒溶劑造成的污染和人身傷害。再次可自動清洗,無需人工重新刷涂,很好地避免了人工清洗過程中的人為損壞和工作場所臟污。清洗后,使用磷酸鹽可以更好地提高耐腐蝕性,改善基材與涂層或其他有機(jī)飾面層之間的附著力,并清潔表面,這可以很好地改善材料的冷加工性能,如拉絲、拉管、擠壓,提高表面摩擦性能,促進(jìn)其滑動。
The application of full-automatic ultrasonic cleaning machine technology to coating pretreatment has the following advantages: first, ultrasonic cleaning of the workpiece surface will achieve a very uniform and clean effect. Using the working principle of the ultrasonic cleaning machine, the bubbles in the cleaning liquid can be uniformly broken and the cleaning is uniform. Second, it does not damage the high-precision surface. If water-based industrial cleaning agent is used instead of traditional strong acid and strong alkali, the environmental pollution caused by strong acid and strong alkali and organic solvent is avoided, which meets the environmental protection requirements. Ultrasonic cleaning can also effectively reduce pollution and personal injury caused by toxic solvents. It can be automatically cleaned again, without manual re brushing, which can well avoid artificial damage and dirty work place during manual cleaning. After cleaning, the use of phosphate can better improve the corrosion resistance, improve the adhesion between the substrate and the coating or other organic finishing layers, and clean the surface. This can well improve the cold processing performance of the material, such as wire drawing, pipe drawing and extrusion, improve the surface friction performance and promote its sliding.
