如何判別即熱式熱水器金屬加熱管的質量

?一種用于冷庫、冷藏柜潮濕極高低溫環境下工作的融霜電熱管端頭密封件的配制工藝,要點為將丁腈膠、天然膠、氧化鋅、防老劑、促進劑、凡士林、環氧樹脂等原料按重量百分配合比聚合成橡膠。然后將電熱管端頭酸洗后涂上CH3COCH3、CHEMLOK205、220與合成橡膠一并壓制而成。本發明從根本上克服了原采用普通電熱管配用橡膠套作融霜電熱管端頭密封性能,防潮、抗凍效果差的弱點。具有制造工藝簡單、安全可靠、耐熱、抗凍、防潮、高絕緣性、使用壽命長等優點,為我國制冷行業解決了一大難題。

For cold storage, refrigerated cabinets humid defrosting electric heating tube end sealing process of a high temperature environment, points to the raw materials acrylonitrile butadiene rubber, natural rubber, Zinc Oxide, antioxidant, accelerator, Vaseline, epoxy resin by weight percent polymerized rubber mix. Then the electric heating tube end after acid coated with CH3COCH3, CHEMLOK205, 220 and synthetic rubber are pressed. The invention overcomes the ordinary electric heating tube with rubber sleeve defrosting electric heating tube end sealing performance is fundamentally, moisture-proof, anti freezing effect is poor. With the manufacturing process is simple, safe and reliable, heat resistance, frost resistance, moisture-proof, high insulation performance, long service life, to solve a big problem for the refrigeration industry in china.
