换热器胶垫板式换热器的密封热片与一般设备的密封垫片有许多不同之处。因此,对垫片材料有着特殊的要求。泉四撅乙稀或其他塑科,金属垫片或石棉绳都不适合〔B)。目前,国外广泛采用的有各种株胶。如夭然橡胶、丁麟橡胶、丁苯梅胶、抓丁橡胶。异丁橡胶、树脂一砚丁基位胶、丧丁稀橡胶、T腑丁笨橡胶、苯乙稀丁基橡胶、硅株胶、等。这些材料的安全使用滋度(见表6-3)-般在150℃以下,皿高的不超过200 t.所以,几年前,国外板式换热器的使用温度都投超过这个范围。此外。橡胶垫片还不耐有机溶荆成蚀。因此,板式换热器的应用在很大程度上受到了限制。近年来,采用了压缩石楠垫片,议在板式换热器的发展中是个萝要的改进。这种新型垫片不仅耐高滋(可耐而月抗有机腐蚀。由于这种垫片的采用,使板式换热器的应用范圈进一步扩大了(的,52, 99, 151)。
