  当我们发现饮用水中铅含量超标时,我们通常会将其归咎于铅管或含铅的黄铜和青铜配件。但一项新的研究表明,镀锌钢管涂层中的铅可能是水中铅的一个重要的长期来源。

  When we find that the lead content in drinking water exceeds the standard, we usually blame it on the lead pipe or lead containing brass and bronze fittings. But a new study shows that lead in galvanized steel pipe coating may be an important long-term source of lead in water.

  当水管不用于超过6个小时,个打开大利用10分钟,管中的水或不喝酒,这是因为管没有使用很长一段时间,水溶解太多会。此外,饮用自来水时,还要特别补充一些营养物质,如钙、锌、维生素E、C、B和蛋白质等,这些物质可以抵抗铅的毒性。

  When the water pipe is not used for more than 6 hours, the first one is opened for large utilization for 10 minutes, and the water in the pipe or does not drink, because the pipe is not used for a long time, and the water dissolves too much. In addition, when drinking tap water, it is necessary to supplement some nutrients, such as calcium, zinc, vitamin E, C, B and protein, which can resist the toxicity of lead.

  目前,我国的自来水管网大多为含铅镀锌管,已使用了5年以上。因此,为了避免铅中毒,如果可能的话,应考虑更换管网或生活用水。在供水工程的分质管道中,使用铜管供水纯水时,一般PH值约为6,铜管、焊缝、龙头处于酸性状态,铅会从管件内大量溶解,因此饮用要非凡注重。

  At present, most of the water pipe networks in China are lead-containing galvanized pipes, which have been used for more than 5 years. Therefore, in order to avoid lead poisoning, if possible, the replacement of pipe network or domestic water should be considered. In the water supply project, when using copper pipe to supply pure water, the pH value is about 6. The copper pipe, weld joint and faucet are in acid state, and lead will dissolve in a large amount from the pipe fittings. Therefore, special attention should be paid to drinking.

  经常饮用纯净水的家庭和个人应该定期补充各种营养物质,特别是钙和镁,这可以防止铅阻止吸收这些营养物质。

  Families and individuals who regularly drink purified water should regularly supplement various nutrients, especially calcium and magnesium, which can prevent lead from absorbing these nutrients.

  铝塑复合管道:

  Aluminum plastic composite pipe:

  镀锌管供水系统的自来水的二次污染和对人体健康的危害已经越来越多的消费者关注,很多消费者在新房子的装修或翻新的旧房子供水管道、几乎所有的性能优于镀锌铝塑料复合管道。但目前市场上铝塑复合管品种较多,质量和价格差异较大。如何选购铝塑复合管,已成为消费者头疼的问题。

  More and more consumers have paid attention to the secondary pollution of the tap water of the galvanized pipe water supply system and the harm to human health. Many consumers in the new house decoration or renovation of the old house water supply pipe, almost all of the performance is better than the galvanized aluminum plastic composite pipe. But at present, there are many varieties of aluminum-plastic composite pipe in the market, and the quality and price are quite different. How to choose aluminum-plastic composite pipe has become a headache for consumers.

  1. 外观

  1. Appearance

  根据相关人的引入,优质铝复合管道,一般光滑的外墙,墙上的商标、规格、适用温度、米和其他明确的识别,制造商也印在墙上的生产数量,以随时监控产品质量;产品包装良好,包装上的标签也很清楚,显眼的位置印着厂家名称、地址、电话等。而劣质产品一般墙壁粗糙,标志不清或不完整,包装简单,工厂地址或电话不明。

  According to the introduction of relevant personnel, high-quality aluminum composite pipes, generally smooth exterior walls, trademarks, specifications, applicable temperature, meters and other clear identification on the walls, manufacturers also print the production quantity on the walls to monitor the product quality at any time; the product packaging is good, the labels on the packaging are also very clear, and the manufacturer's name, address, telephone number, etc. are printed in a conspicuous position. But the inferior products generally have rough walls, unclear or incomplete marks, simple packaging, and unknown factory address or telephone number.

  2. 铝层不可忽视

  2. Aluminum layer cannot be ignored

  好铝塑复合管,在铝层搭接焊接时,铝层与塑料层紧密接触,无分层现象,而且假冒产品有的铝层搭接不焊,有的铝层与塑料层经常分层,不紧密。

  Good aluminum-plastic composite pipe, when the aluminum layer is overlapped and welded, the aluminum layer and the plastic layer are in close contact, and there is no layering phenomenon. In addition, some aluminum layers of counterfeit products are overlapped and not welded, and some aluminum layers and plastic layers are often layered and not close.

  3.价格差异

  3. Price difference

  目前,市场上销售的铝塑料复合管道,价格有很大的不同,一些1 - 2元每米,7 - 10元每米,根据铝塑料复合管道的生产成本分析,价格过低的产品,原材料的质量不能保证。因此,消费者在购买时,不能贪图便宜。实际上,一些大企业的生产能力不断提高,生产成本不断降低,一些著名品牌产品的价格也在下降,装饰铝塑复合管,住房需求的现在,名牌和普通产品总价值只有几十元不同,所以购买的产品有一定的声望是明智的选择。

  At present, the prices of the aluminum plastic composite pipes sold on the market are quite different. Some are 1-2 yuan per meter, 7-10 yuan per meter. According to the production cost analysis of the aluminum plastic composite pipes, the quality of the raw materials for the products with low prices cannot be guaranteed. Therefore, consumers should not be greedy for cheap when they buy. In fact, the production capacity of some large enterprises is constantly improving, the production cost is constantly reducing, and the price of some famous brand products is also declining. Nowadays, the total value of famous brand and ordinary products is only tens of Yuan different with the demand for decorative aluminum-plastic composite pipes and housing. Therefore, it is a wise choice to purchase products with a certain reputation.

  PPR管:

  PPR pipe:

  PPR管的正式名称为无规共聚物聚丙烯管,是目前国内使用更多的一种安装供水管道。

  The official name of PPR pipe is random copolymer polypropylene pipe, which is the most widely used water supply pipe in China.

  PPR管的接口采用热熔技术,管道完全集成,所以一旦安装压力测试通过,水就不会再泄漏,可靠性非常高。但这并不是说PPR水管不是有缺陷的水管,耐高温、耐压稍差,长期运行温度不能超过70℃;每一节的长度是有限的,且不能弯曲施工,如果铺设管道的距离较长或转角较多,在施工时会用到大量的接缝;管道很便宜,但配件相对昂贵。从综合性能上讲,PPR管道是目前性价比较高的管道材料,所以成为家装管道改造的首选材料。

  The interface of PPR pipe adopts hot-melt technology, and the pipe is fully integrated, so once the installation pressure test is passed, the water will not leak again, and the reliability is very high. But this is not to say that PPR water pipe is not a defective water pipe, which is slightly poor in high temperature resistance and pressure resistance, and the long-term operating temperature cannot exceed 70 ℃; the length of each section is limited, and bending construction is not allowed. If the distance to lay the pipe is long or there are many corners, a large number of joints will be used during construction; the pipe is very cheap, but the accessories are relatively expensive. In terms of comprehensive performance, PPR pipeline is currently the pipeline material with high cost performance, so it has become the preferred material for home installed pipeline transformation.

  市场上销售的PPR管主要有三种颜色,白色、绿色和灰色,为什么会有这种差异,经销商的回答是使用原材料PPR颗粒和不同的填料造成的差异。其中,灰绿色是质量较好的PPR管材,灰色是质量稍差的早期普通管材。

  There are three main colors of PPR pipes sold on the market: white, green and gray. Why is there such a difference? The dealer's answer is the difference caused by the use of raw material PPR particles and different fillers. Among them, grey green is the PPR pipe with good quality, and grey is the early ordinary pipe with slightly poor quality.

  一般在水电改造中,原来的水管可以更换,家装公司和商家在建议装修人安装PPR安装时都选用热水水管,即使是经过冷水的地方也用热水水管。这是因为热水管的技术参数比冷水管高,而且价格差异不大,所以水管用于航道改造。

  In general, the original water pipe can be replaced in the water and electricity transformation. Home decoration companies and businesses recommend that decorators use hot water pipes when installing PPR, even in places where cold water has passed. This is because the technical parameters of hot water pipe are higher than that of cold water pipe, and the price difference is not big, so the water pipe is used for waterway reconstruction.
