壓鑄鋁發黑、氧化、發霉的原因-羽杰科技
? ? ? ?羽杰科技：壓鑄鋁制品表面發黑，特別是在經過機加工以后會更加明顯，表現為黑點黑斑。這種情況可能是壓鑄時壓力不夠，工件致密度不夠，所以形成毛細孔，這些毛細孔吸水被氧化后就會出現這種問題。
? ? ? ?The surface of die-casting aluminum alloy products is blackened, especially after machining, which is shown as black spots and black spots. This situation may?It is because the pressure is not enough and the density of the workpiece is not enough during die casting, so pores are formed. This problem occurs after the pores absorb water and are oxidized
? ? ? ?一鋁合金壓鑄件發霉變黑的原因分析Cause Analysis of Mold and Blackening of an Aluminum Alloy Die Casting
? ? ? ?其一，外部環境因素。鋁是活潑金屬，在一定的溫度和濕度條件下極易氧化變黑或發霉，這是鋁本身特性決定的。
? ? ? ?First, external environmental factors. Aluminum is an active metal, which is easily oxidized and blackened or mildewed under certain temperature and humidity conditions, which is determined by the characteristics of aluminum itself.
? ? ? ?其二，自身的內部因素。很多廠家壓鑄、機加工工序之后，不做任何清潔處理，或者簡單的用水沖沖，無法做到徹底清洗干凈，壓鑄鋁表面殘留有脫模劑、切削液、皂化液等腐蝕性物質，以及其他污漬，這些又加快鋁合金壓鑄件長霉點；
? ? ? ?Second, internal factors. After the die casting and machining processes, many manufacturers do not do any cleaning treatment, or simply flush with water, which can not be completely cleaned. The surface of die cast aluminum remains corrosive substances such as mold release agent, cutting fluid, saponification fluid, and other stains, which accelerates the growth of mold spots in aluminum alloy die castings;
? ? ? ?其三，工藝設計不合理。鋁合金壓鑄件在清洗或壓檢后處理不當，為鋁合金壓鑄件發霉創造了條件，加速霉變的生成；
? ? ? ?Third, the process design is unreasonable. Improper treatment of aluminum alloy die castings after cleaning or pressure inspection creates conditions for aluminum alloy die castings to become mouldy and accelerates the formation of mouldy;
? ? ? ?其四，選用清洗劑不得當。清洗具有強腐蝕性，造成壓鑄鋁腐蝕氧化。其五，倉儲管理不到位。存放倉庫不同的高度時，發霉的狀況也不同。
? ? ? ?Fourth, the cleaning agent is inappropriate. The cleaning is highly corrosive, causing corrosion and oxidation of die cast aluminum. Fifth, warehousing management is not in place. When the storage warehouse is at different heights, the mildew condition is different.
? ? ? ?采取對策：從壓鑄鋁發霉的原因分析，我們不難得出這樣的結論：防氧化問題非單一因素造成的，他涉及內外部、工藝、倉儲等多個方面。
同時清洗、壓檢、存放、運輸等各個過程都需要考慮防氧化，哪個環節出現問題，都會長霉點給你看。故這是一個綜合問題，需制定整體解決方案。
? ? ? ?Countermeasures: From the analysis of the causes of mould forming of die cast aluminum, we can easily draw the conclusion that the oxidation prevention problem is not caused by a single factor, it involves internal and external, process, storage and other aspects.
At the same time, anti oxidation should be considered in all processes such as cleaning, pressure inspection, storage and transportation. If any problem occurs in any link, you will see the mildew. Therefore, this is a comprehensive problem, and an overall solution is needed.
? ? ? ?羽杰科技從壓鑄鋁清洗劑、壓鑄鋁防氧化劑、工藝、存放環境、存放方式等角度出發，解決了鋁合金壓鑄件發霉的難題，并可提供壓鑄鋁清洗、壓檢、存放各個過程的防氧化解決方案。
? ? ? ?From the perspective of die casting aluminum cleaner, die casting aluminum antioxidant, process, storage environment, storage mode, Yujie Technology has solved the problem of aluminum alloy die castings becoming moldy, and can provide anti oxidation solutions for all processes of die casting aluminum cleaning, pressure inspection, and storage.
