不锈钢电热管即热式 电热水器的使用性能及安全性能如何,主要取 决于其采用的加热器,目前国 内市场中即热式电热水器的加热器用材一

般分为以下几类: 不锈钢 不锈钢护套加热器:不锈钢加热管不锈钢加热管不锈钢加热管不锈钢加热管技术较早,但由于 不锈钢材质延展性差,发热管金属护 套及内胆均采用有缝不锈钢管合成的加热器,布满了焊缝(发热管越多,焊缝就越多),加热管的表面负载高,因此易结水垢,这种先 天缺陷不可避免,严重影 响金属加热体的散热,轻则加热时间延长,费电,重则造 成发热丝热能传导不出,使护套 管中的加热丝在短期内易断裂,从而水 中带电危及安全.就算加 装镁棒来保护加热体,由于容积的限制,也只能 在一定程度上缓解结垢问题,所以不 锈钢加热器一般都做成可拆卸的,只能靠 定期清洗和保养.同时又 造成拆装过程中密封不好的问题,存在安全隐患.Stainless steel electric heating tube is the use of performance and the safety performance of electric water heater, mainly depends on the heater, the current domestic market the heater for electric water heater is divided into the following categories: stainless steel sheath heater: stainless steel heating pipe heating pipe heating pipe stainless steel stainless steel stainless steel heating pipe technology earlier, but because of poor ductility of stainless steel material, heating pipe metal sheath and liner adopt welded stainless steel pipes for synthesis of heater, full of weld (heating pipe is more, more seam), heating tube surface load is high, so easy to scale, this defect is unavoidable, seriously affecting the metal heating body heat, light then the heating time prolonged, electricity costs, weight is caused by the heating wire heat conduction not, make the heating wire protective sleeve pipe rupture easily in the short term, thus endangering the safety of water charged. If adding magnesium stick to protect the heating body, because the volume limit, also can alleviate the scaling problem in a certain extent, so stainless steel heaters are generally made into detachable, can only rely on regular cleaning and maintenance. And at the same time caused disassembly process seal is not good, the existence of security risks能大大优于不锈钢,同时,无氧紫 铜材质的延展性强,所以采 用无缝纯紫铜管及铜管焊,可减少焊缝的数量,铜的电 位比水中杂质元素的电位要低很多,不会受到电腐蚀,从根本 上杜绝了水垢的危害并提高了热效率.根据<中国日 用电器质量监督检测中心电热水器具实验室>最近的检验报告以及<中国疾 病预防控制中心>对水家 电相关的测试结果均显示:无氧紫 铜加热器在其选材以及设计中表明其100%抗菌性,抗霉性 均在检测的材料中名列榜首.但无氧 紫铜的材料成本是不锈钢材料成本的4倍,成本太高,影响了 其在即热式电热水器行业中的广泛应用. 因此,无氧紫 铜在即热式电热水器核心部件的运用已大大提高了热水器的安全系数,也成为高,低端快 速电热水器划分的分水岭. 外壳须带保护甲 除了加热器外,外壳材 料也对即热式电热水器安全防护的又一重保护甲.一般来说,目前市 场上快速电热水器的外壳材质主要有金属面板,如:铁,不锈钢,普通塑料或压膜,如各种金色,银色及彩色膜;另外还有ABS特种胶料等几种外壳. 热水器 长期处于潮湿的环境中使用,应该采用ABS特种胶做成的外壳,其特性表现为阻燃,耐热性耐化学性高,抗拉强度,抗冲击强度,表面硬 度高等先天优点 以上介 绍了几种不同材料的加热管进行比较Can greatly better than that of stainless steel, at the same time, oxygen-free copper material ductility is strong, so the use of pure copper and copper welding, can reduce the number of copper weld, the potential than the potential impurity elements in water is much lower, not subject to corrosion, fundamentally eliminate the scale effects and improve the thermal efficiency. According to the < Chinese household electrical appliances Quality Supervision Testing Center of electric water heater laboratory > recent inspection report and the Chinese Center for Disease Control and prevention of water appliances > test results showed: oxygen-free copper heater shows that the 100% antibacterial material and in its design, mold resistance are among the top in the test material. But the anaerobic copper material cost is 4 times the cost of stainless steel materials, the cost is too high, affecting its application in electric water heater industry. Therefore, the oxygen-free copper in electric water heater core components has greatly enhanced the safety factor of water heater, also become high, divide the low-end fast electric water heater is divided. Shell with a heater shall be protected from outside, the shell material of instant electric water heater safety protection and a heavy armour. Generally speaking, the current market fast electric water heater The shell material mainly metal panels, such as: iron, stainless steel, plastic or film, such as gold, silver and color film; in addition to the ABS material, special glue several housing. Water heater in the long-term use of damp environment, outer shell should be made ABS special glue, the characteristics of the performance of flame retardant, chemical resistance of high heat resistance, tensile strength, impact strength, hardness higher inherent advantages over the heating of different materials are compared several tube
