为了配合冷硬树脂沙工艺的推广应用,我们试制了一种有色合金冷硬树脂砂型(芯)快干树脂余料。我们在铝、铜合金铸件的批量生产中采用了这种涂料,实践证明效果较好。现已纳入我厂冷硬树脂砂工艺的正常生产使用。一、涂料的基本组成一种涂料一般都含有四种基本成分:耐火填料、粘结剂、悬浮稳定剂和稀释剂。 1。耐火填料:耐火填料是涂料的最基本成分,通常要求热化学稳定性 In order to cope with the popularization and application of chilled resin sand craft, we trialled a non-ferrous alloy chilled resin sand (core) quick-drying resin residue. We used this kind of coating in mass production of aluminum and copper alloy castings, which proved to be effective. Has now been incorporated into the normal production and use of our factory cold and hard resin sand process. First, the basic composition of a coating A coating generally contains four basic components: refractory filler, binder, suspension stabilizer and diluent. 1. Fire-resistant filler: Fire-resistant filler is the most basic ingredients of coatings, usually require thermal chemical stability
