    覆膜砂铸造的作用根据类别的不同,大概分为以下几种:

    The functions of coated sand casting can be roughly divided into the following types according to different categories:

    普通类覆膜砂 由石英砂、热塑性酚醛树脂、乌洛托品和硬脂酸钙组成,不加有关添加剂。适用于生产一般铸铁件。

    Ordinary coated sand is composed of quartz sand, thermoplastic phenolic resin, urotropine and calcium stearate without relevant additives. It is suitable for producing general iron castings.

    高强度低发气类覆膜砂 是普通覆膜砂的更新换代产品,通过加入有关添加剂和采用新工艺配制而成,其强度比普通覆膜砂高30%以上,发气量也明显降低,适用于生产复杂精密铸铁件。

    High strength low gassing coated sand is an updated product of ordinary coated sand. It is prepared by adding relevant additives and adopting new processes. Its strength is more than 30% higher than that of ordinary coated sand, and its gas generation is also significantly reduced. It is suitable for the production of complex precision iron castings.

    高温类覆膜砂 在高温下具有强度高、耐热时间长的特性,适用于生产汽车发动机缸体、缸盖、集装箱角等复杂薄壁铸铁件。

    High temperature coated sand has the characteristics of high strength and long heat resistance time at high temperature. It is suitable for the production of complex thin-walled iron castings such as automobile engine cylinder block, cylinder head and container angle.

    易溃散类覆膜砂 具有较好的强度,同时具有优异的低温溃散性能,适用于生产有色金属铸件。

    The easily collapsible coated sand has good strength and excellent low-temperature collapsibility. It is suitable for the production of non-ferrous metal castings.

    其它特殊要求覆膜砂 为适应不同产品的需要,开发出了系列特种覆膜砂如:离心铸造用覆膜砂、激冷覆膜砂、湿态覆膜砂、防粘砂、防脉纹、防橘皮覆膜砂等。

    Other special requirements coated sand in order to meet the needs of different products, a series of special coated sand have been developed, such as coated sand for centrifugal casting, chilled coated sand, wet coated sand, anti sticking sand, anti vein, anti orange peel coated sand, etc.
