如何解决自动上料搅拌车钢制水箱的锈蚀问题

所属分类:常见问题 发布时间:2022-01-10 来源:http://www.shanqijituan.com 浏览量:18

目前生产企业对钢制水箱防锈处理的方式主要有两种:
At present, there are two main methods for rust prevention treatment of steel water tanks by manufacturers:
一是镀锌处理,水箱做好后送到镀锌厂电镀,这种方法成本较高,且费时。
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.
二是企业自行做防腐处理,酸洗除锈→浸泡磷化液中→水箱内倒入防锈漆后再倒出→烘干。这种处理因不是厂家的规范操作,质量就难以得到保证。关键是目前大多数专用车企业没有酸洗、磷化工装,基本上未对钢制水箱做防腐处理。钢铁生锈的反应机理为铁分子与空气中的氧气、水发生氧化反应,所以只要有空气和水的存在,钢制水箱生锈就在所难免。好在为了保证标准压力下水箱的强度,所用钢板至少有 厚度,因此水箱在使用寿命内不容易因锈蚀而漏水,即使坏了,维修或更换也较方便,且价格低廉。
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.

承压水箱为目前搅拌车生产厂家主要采用的水箱。此类水箱因承受一定压力大多采用钢制,一般筒体采用3~4mm 的 Q235钢板卷制,封头采用 4~5mm的Q235 钢板或4mm的Q235钢板制成。其内部容易生锈,需做涂层防护,但目前大多数厂家为了减少成本,均不做防腐处理。
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.
从技术角度考虑,我认为主承压水箱为目前搅拌车生产厂家主有两个途径解决锈蚀问题。
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.
一是从现有产品的工艺加工和质量控制上考虑,如镀锌处理,较适合追求低成本的汽车厂家,工艺灵活,产品改型也较容易。然而电镀的缺点也较多,工艺要求严格,产品质量控制困难,特别是焊接处锈蚀仍不好处理,等等。如果采用浸镀工艺,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.
二是从产品的材料上考虑。目前可替代的材料主要有不锈钢、塑料 含玻璃钢 和铝合金等。这几种材料都能够完全解决产品的锈蚀问题,但由于每种材料的加工工艺不同,又都存在着各自的优缺点。
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.
钢制水箱适用于气压式供水,制作简易、维修方便。 年前有企业采用配水泵使用的玻璃钢水箱,价格较便宜、质量轻,不易生锈。但缺点是易破碎,不易修,且不适宜气压式供水。塑料水箱目前多用于客车上的饮用车载水箱和卡车上,其质量轻、环保,强度也较高,开始有向工程车上推广使用的趋势。塑料箱体本身的承压应能满足要求,但接头部分的密封要处理好,好配水泵使用。还应做低温脆性的防护处理,但这样会增加生产成本。
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.

铝合金水箱质量轻、耐腐蚀、美观,承压也没问题,但是成本过高,成型、焊接都相对复杂。玻璃钢水箱易破碎,铝合金水箱成本太高。塑料水箱可以推广,材料为工程塑料,目前市场上比较常见。但是塑料水箱一般都是水泵供水,如果要承受压力,是否可行还需要试验再定。
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.
玻璃钢水箱损坏后,环保是一大问题。现在国外对玻璃钢制品均限制进口,所以不论其性能和成本如何,玻璃钢水箱不应成为发展的方向。塑料可回收利用,可开发性强。
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观效果,不能类似水桶、塑料盆等普通塑料制品。并能适应各种搅拌车颜色的需要,同时还要保证颜色不易褪色。
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,在北方地区需要考虑使用环境温度,同时,应注意水箱在整车的布置位置;钢制水箱在沿海地区需要注重防锈问题;玻璃钢水箱的脆性较大,必须考虑水箱的布置位置和防护;铝合金水箱质量轻,防腐效果好,适应性较强,但成本高;不锈钢水箱防腐效果好,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.
塑料和铝合金材质在轻量化及可回收方面都优于其他材质。在目前油价上涨、运输成本提高、降耗减排的大环境和市场竞争的压力下,只要产品的价格控制在一个合理的范围内,逐渐形成回收、维修、销售一条龙的产业链,塑料和铝合金就可以成为今后替代钢制品的主要发展方向,至于客户选择和使用哪种材料则是“仁者见仁,智者见智”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".
