搬了新房我们第一件事就是装修，涂料是我们装修中最常遇到的东西了，那大家对它的了解有多少呢?平时装修的时候有各式各样的装修材料和涂料，大家有没有听说过消失模涂料呢?消失模涂料分铸铁消失模涂料，铸钢消失模涂料，合金钢消失模涂料。今天呢，小编就来给大家来介绍下消失模涂料和它的性能，、基本组成，希望能给大家带来帮助哦！
铸件的好坏主要取决于消失模涂料，消失模涂料的配比是至关重要的工序。我国在全面掌握消失模铸造工艺技术的基础上，山东工业大学等一些大专院校的消失模专家研究消失模涂料配比的工艺、技术，总结经验、教训。多次利用小批量反复对比试验，终于掌握了消失模涂料最佳组合方案，确保了消失模涂料配比的质量，使得白模的涂刷简单且质量好，工艺易于掌握，铸件成品消失模涂料层的一次性脱落百分比进一步提高，外表光滑，合格率也直线上升。现在我们已经不需要进口消失模涂料。
耐高温消失模涂料是以水为载体，颜色为红色和黑色，无毒、无味、无污染，抗粘砂性好，能使泡塑模型表面上形成致密的高强度涂层，消失模涂料具有较好的悬浮性，能在空气中自然干燥或经45-55℃烘干均可。
消失模涂料的性能包括众多指标：轻度、透气性、耐火度、绝热性、耐急冷急热性、吸湿性、清理性、涂挂性、滴淌性、悬浮性等，这些性能指标可以归纳为两类：工作性能和工艺性能。涂料的强度、透气性、耐火性、绝热性、耐急冷急热性等均为工作性能，涂料的涂挂性、滴淌性和悬浮性等则属于工艺性能。
消失模涂料要具有高温透气性。在消失模铸造设备上，涂料的高温透气性很大的程度上直接影响铸件的品质问题，高温是指涂层的耐火性一定好，热膨胀系数要低，涂料的透气作用是确保模型气化所生成的气体可以通过涂层，通过型料之间的间隙由阵痛泵抽走。第二，消失模涂料要具有很好的涂挂性。涂料的涂层比较厚，因此，对于涂料的要求一定要有塑性变形的能力，严格地控制涂料的流淌性，对热固性树脂为粘结剂的涂料，可以在其中加入少量的触变剂，用来提高涂料的涂挂性。第三，消失模涂料要具有很好的润湿性，在涂料中添加适量的表面活性剂与粘结剂，在涂挂后能够得到优良的铸件！
以上就是小编今天所讲述的主要内容，消失模涂料性能没想到那么强大吧!可是我们平时经常用到的哦!小编也在这提醒大家，在装修新房子的时候，不仅要美观大方，物美价廉，还要注意的是要挑选对我们身体无害的材料去使用，以防一时的疏忽给我们带来不必要的困扰!今天小编的提醒大家可以放在心上，大家有木有记住呢！
