水玻璃砂微波加热工艺及工程应用方案研究

Study on the Technology and Engineering Application Method of Sodium Silicate Bonded Sand Cured by Microwave Energy

系统测试和分析了水玻璃模数Ｍ、加入量、微波加热工艺对微波固化水玻璃砂抗拉强度σｂ 和高温烘焙后的残留强度σｂｃ 的影响规律。发现水玻璃砂微波加热时间过长抗拉强度有降低趋势。提出了水玻璃砂微波加热工艺的工程应用方案。

The Influences of modulus and dosage of sodium silicate and microwave energy heat up technology for instant strength and retained strength are measured and analyzed by the numbers. The results show that instant strength is reduced when the time of microwave energy heat up is too long. The engineering application design is recommended.
