            如何解決自動上料攪拌車鋼制水箱的銹蝕問題

            目前生產企業對鋼制水箱防銹處理的方式主要有兩種:
            At present, there are two main methods for rust prevention treatment of steel water tanks by manufacturers:
            一是鍍鋅處理,水箱做好后送到鍍鋅廠電鍍,這種方法成本較高,且費時。
            One is galvanizing treatment. After the water tank is completed, it is sent to the galvanizing plant for electroplating. This method has high cost and time-consuming.
            二是企業自行做防腐處理,酸洗除銹→浸泡磷化液中→水箱內倒入防銹漆后再倒出→烘干。這種處理因不是廠家的規范操作,質量就難以得到保證。關鍵是目前大多數專用車企業沒有酸洗、磷化工裝,基本上未對鋼制水箱做防腐處理。鋼鐵生銹的反應機理為鐵分子與空氣中的氧氣、水發生氧化反應,所以只要有空氣和水的存在,鋼制水箱生銹就在所難免。好在為了保證標準壓力下水箱的強度,所用鋼板至少有 厚度,因此水箱在使用壽命內不容易因銹蝕而漏水,即使壞了,維修或更換也較方便,且價格低廉。
            Second, the enterprise shall carry out anti-corrosion treatment by itself, pickling and derusting → soaking in phosphating solution → pouring antirust paint into the water tank and then pouring it out → drying. Because this treatment is not the standard operation of professional manufacturers, the quality is difficult to be guaranteed. The key is that at present, most special vehicle enterprises do not have pickling and phosphorus chemical equipment, and basically do not do anti-corrosion treatment for steel water tanks. The reaction mechanism of steel rust is the oxidation reaction between iron molecules and oxygen and water in the air. Therefore, as long as there is air and water, the rust of steel water tank is inevitable. Fortunately, in order to ensure the strength of the water tank under standard pressure, the steel plate used is at least thick, so the water tank is not easy to leak due to corrosion within its service life. Even if it is broken, it is convenient to repair or replace, and the price is low.
            如何解決自動上料攪拌車鋼制水箱的銹蝕問題及不同材質的水箱有哪些優缺點?
            How to solve the corrosion problem of steel water tank of automatic feeding mixer truck and what are the advantages and disadvantages of water tanks of different materials?
            承壓水箱為目前攪拌車生產廠家主要采用的水箱。此類水箱因承受一定壓力大多采用鋼制,一般筒體采用3~4mm 的 Q235鋼板卷制,封頭采用 4~5mm的Q235 鋼板或4mm的Q235鋼板制成。其內部容易生銹,需做涂層防護,但目前大多數廠家為了減少成本,均不做防腐處理。
            The pressurized water tank is the main water tank used by mixer manufacturers at present. Most of these water tanks are made of steel because they bear certain pressure. Generally, the cylinder is made of 3 ~ 4mm Q235 steel plate, and the head is made of 4 ~ 5mm Q235 steel plate or 4mm Q235 steel plate. Its interior is easy to rust and needs coating protection, but at present, most manufacturers do not do anti-corrosion treatment in order to reduce costs.
            從技術角度考慮,我認為主承壓水箱為目前攪拌車生產廠家主有兩個途徑解決銹蝕問題。
            From a technical point of view, I think the main pressure bearing water tank is the main of the current mixer manufacturer, and there are two ways to solve the corrosion problem.
            一是從現有產品的工藝加工和質量控制上考慮,如鍍鋅處理,較適合追求低成本的汽車廠家,工藝靈活,產品改型也較容易。然而電鍍的缺點也較多,工藝要求嚴格,產品質量控制困難,特別是焊接處銹蝕仍不好處理,等等。如果采用浸鍍工藝,成本更高。
            First, considering the process processing and quality control of existing products, such as galvanizing treatment, it is more suitable for automobile manufacturers pursuing low cost, with flexible process and easy product modification. However, electroplating has many disadvantages, strict process requirements, difficult product quality control, especially the corrosion of welding joint is still difficult to deal with, and so on. If the dip coating process is adopted, the cost is higher.
            二是從產品的材料上考慮。目前可替代的材料主要有不銹鋼、塑料 含玻璃鋼 和鋁合金等。這幾種材料都能夠完全解決產品的銹蝕問題,但由于每種材料的加工工藝不同,又都存在著各自的優缺點。
            Second, consider the material of the product. At present, the replaceable materials mainly include stainless steel, plastic, including FRP and aluminum alloy. These materials can completely solve the corrosion problem of products, but due to the different processing technology of each material, they all have their own advantages and disadvantages.
            鋼制水箱適用于氣壓式供水,制作簡易、維修方便。 年前有企業采用配水泵使用的玻璃鋼水箱,價格較便宜、質量輕,不易生銹。但缺點是易破碎,不易修,且不適宜氣壓式供水。塑料水箱目前多用于客車上的飲用車載水箱和卡車上,其質量輕、環保,強度也較高,開始有向工程車上推廣使用的趨勢。塑料箱體本身的承壓應能滿足要求,但接頭部分的密封要處理好,好配水泵使用。還應做低溫脆性的防護處理,但這樣會增加生產成本。
            The steel water tank is suitable for pneumatic water supply, with simple manufacture and convenient maintenance. Years ago, some enterprises used FRP water tanks for water distribution pumps, which were cheap, light and not easy to rust. But the disadvantage is that it is easy to break, difficult to repair, and not suitable for pneumatic water supply. At present, plastic water tanks are mostly used in drinking water tanks on passenger cars and trucks. They are light, environmentally friendly and have high strength. They begin to be popularized to engineering vehicles. The pressure bearing of the plastic box itself shall meet the requirements, but the sealing of the joint part shall be handled well for use with the water pump. Low temperature brittleness protection treatment should also be done, but this will increase the production cost.

            How to solve the corrosion problem of steel water tank of automatic feeding mixer truck and what are the advantages and disadvantages of water tanks of different materials?
            鋁合金水箱質量輕、耐腐蝕、美觀,承壓也沒問題,但是成本過高,成型、焊接都相對復雜。玻璃鋼水箱易破碎,鋁合金水箱成本太高。塑料水箱可以推廣,材料為工程塑料,目前市場上比較常見。但是塑料水箱一般都是水泵供水,如果要承受壓力,是否可行還需要試驗再定。
            Aluminum alloy water tank is light, corrosion-resistant, beautiful, and has no problem with pressure, but the cost is too high, and the forming and welding are relatively complex. FRP water tank is easy to break, and the cost of aluminum alloy water tank is too high. Plastic water tank can be popularized. The material is engineering plastic, which is common in the market at present. However, plastic water tanks are generally supplied by water pumps. If they want to bear pressure, whether it is feasible still needs to be tested.
            玻璃鋼水箱損壞后,環保是一大問題?,F在國外對玻璃鋼制品均限制進口,所以不論其性能和成本如何,玻璃鋼水箱不應成為發展的方向。塑料可回收利用,可開發性強。
            After the FRP water tank is damaged, environmental protection is a big problem. At present, foreign countries restrict the import of FRP products, so FRP water tanks should not become the direction of development regardless of their performance and cost. Plastics can be recycled and developed.
            塑料水箱需要具有良好的外觀效果,不能類似水桶、塑料盆等普通塑料制品。并能適應各種攪拌車顏色的需要,同時還要保證顏色不易褪色。
            The plastic water tank needs to have good appearance effect and can not be similar to ordinary plastic products such as buckets and plastic basins. It can meet the needs of various mixer colors, and ensure that the color is not easy to fade.

            如果采用塑料水箱,在北方地區需要考慮使用環境溫度,同時,應注意水箱在整車的布置位置;鋼制水箱在沿海地區需要注重防銹問題;玻璃鋼水箱的脆性較大,必須考慮水箱的布置位置和防護;鋁合金水箱質量輕,防腐效果好,適應性較強,但成本高;不銹鋼水箱防腐效果好,成本也高。
            If the plastic water tank is used, the ambient temperature shall be considered in the north, and the layout position of the water tank in the whole vehicle shall be paid attention to; Steel water tanks need to pay attention to rust prevention in coastal areas; FRP water tank is brittle, so the layout position and protection of water tank must be considered; Aluminum alloy water tank has light weight, good anti-corrosion effect, strong adaptability, but high cost; Stainless steel water tank has good anti-corrosion effect and high cost.
            塑料和鋁合金材質在輕量化及可回收方面都優于其他材質。在目前油價上漲、運輸成本提高、降耗減排的大環境和市場競爭的壓力下,只要產品的價格控制在一個合理的范圍內,逐漸形成回收、維修、銷售一條龍的產業鏈,塑料和鋁合金就可以成為今后替代鋼制品的主要發展方向,至于客戶選擇和使用哪種材料則是“仁者見仁,智者見智”了。
            Plastic and aluminum alloy materials are superior to other materials in lightweight and recyclability. Under the current environment of rising oil prices, increasing transportation costs, reducing consumption and emission reduction and the pressure of market competition, as long as the price of products is controlled within a reasonable range and a one-stop industrial chain of recycling, maintenance and sales is gradually formed, plastics and aluminum alloys can become the main development direction of replacing steel products in the future, As for what kind of materials customers choose and use, it is "different people see different people, different people see different things".
