龙头: 结束 “灾难” **
水龙头与人们的日常生活息息相关, 而水龙头的安全极大地影响着人们的健康. 最近几年, 水龙头健康问题引发社会恐慌, 而温州水龙头“带铅”事件引发五金卫浴行业危机. 水是生命之源, 水龙头是 “生命之门”. 细流从水龙头流出. 如果水龙头材料中含有的铅元素析出并带入人体, 这将把它带给数百万家庭. 潜在的健康危害, 水龙头铅中毒问题已成为社会问题, 这也带来了 “阴霾” 到水龙头市场.
虽然水龙头含铅量影响人体健康,被公认为居民饮水隐患, tracing the source of damage to the water source shows that the “guilt” of faucets is not so serious. 且不论水龙头所使用的重金属元素对人体的影响, 从供水系统与水流的接触面积来看, the faucet is not a source of damage to the residents’ 饮用水供应系统.
“水龙头的含铅量肯定会对自来水的含铅量产生一定的影响, 但水龙头是最终产品, 位于整个供水管道的末端, 也是影响最小的部分。” Wang Jiade, manager of the Sanitary Quality Management Department, 当谈论到 “带领” 水龙头的, bluntly said that although the faucet contains heavy metal elements which is destructive to drinking water, 水龙头位于 “后几厘米” 整个供水系统的, 所以它与水流接触. “区域” and friction are far inferior to other transportation links.
水管: 长期 “原因” 水
实际上, water pipes have been “favored” by CCTV long before the faucet was “leaded” out of the public eye. 一月 21, 2014, 中央电视台的 “焦点访谈” program exposed major quality problems in domestic water pipe production. 水管, 作为人们饮用水的管道, 不仅影响住户的清洁卫生’ 长期喝水 “正面” 区域, but also bury a huge hidden danger for drinking water through the deep “地下”. 有专家表示, 对比“生命之门”水龙头带来的二次污染, 生命通道“水管”因其“长期作战”,对水的污染程度远大于水龙头.
回顾一月份的闭路电视录像 21, 2014, 它是 “焦点访谈” program exposed major quality problems in domestic water pipes. 根据报道, the main materials of water pipes in my country are cement pipes, 铸铁管, 钢管和塑料管, 其中塑料管道占 30%. 即使在新增加的水管中 2012, 塑料管道占一半! 央视公布了我国部分水管产区企业利用水管、电缆包布等破碎料作为水管生产原料的图片. Using these highly toxic chemical barrels to crush the green barrels is very likely to leave harmful substances, and using these as raw materials requires the addition of plasticizers and other substances in the processing process. These substances are mixed in the pipes and are also harmful to the people’s bodies. 会造成很大的危害,甚至致癌.
Since tap water pipes are in direct contact with drinking water, the country has strict drinking water standards for this. 根据规定, 生产原料应为白色高级聚乙烯或聚丙烯颗粒; 然而, 我国自来水管制造现状不容乐观. 低价竞争, 使用有毒二次回收材料生产水管. 与含有微量的水龙头相比 “带领” 元素, 这 “材料” 水管生产过程中含有的有毒元素大大超过 “铅含量” 水龙头的.
“饮用水污染源排查是一个系统性问题. 我国现有城市供水管道大部分建于20世纪80年代和90年代. Most of these pipelines are made of cast iron, 水泥, 或其他材料. 安装在地下的有毒自来水管很难找到, and the replacement life is 50 年. Once there is a risk of cancer, 对当地居民的危害是长期的. These are the sources of drinking water pollution.” 一位业内资深人士告诉记者. 不顾水管高级材料所含有毒元素对水体的污染, or the contact area of the water pipes in the entire water supply system and the water flow, 水污染程度惊人.
直接命中: 水龙头行业现状
虽然水管比水龙头对饮用水的危害更大, 毕竟, 水龙头仍然损害人们的饮用水. What is the status of my country’s faucet industry today?
根据记者的理解, 我国水龙头厂家中, 85% 的公司使用黄铜作为原材料, 关于 10% 的公司使用锌合金作为原材料, 以及关于 5% of companies use plastics as materials. 水龙头行业仍然生产铜材料. 主要材质. 作为生产水龙头的主要原材料, copper materials are mainly “首选” by manufacturers due to their obvious advantages: **, 铜是一种易于加工的材料,国内外有数百年的生产经验; 第二 , Copper is the best antibacterial material, 有利于保护人体健康、保持卫生. 根据美国环境保护署的数据, 铜多于 99% 杀菌的. Compared with other materials, including stainless steel, 铜含有汞. If this problem is not handled properly, 对人体的危害比铅毒还要大. 然而, zinc alloy is used as a raw material, 因为它比铜贵, 而且材质很难控制, 并且有很多杂质, 所以在生产中使用较少. 以塑料为原料, 产品质量控制有问题, 而且风险比铜锌合金大很多. 所以, 迄今为止, 铜仍是水龙头生产的主要原材料.
记者从业内资深人士处了解到,作为近年来兴起的五金卫浴行业, 目前有近千个水龙头品牌. 经过十多年的发展, 大多数水龙头企业仍处于中小型规模, 并且可以达到国际标准. 国产品牌很少. 在产品质量方面, 设计水平, 和过程级别, 我国水龙头生产水平与国际水平还有一定差距. 尽管国家及相关部门和协会一直呼吁企业提高产品质量, 现阶段能够达到国家标准的企业并不多. 虽然我国水龙头行业发展仍然滞后, 还有一批能够与国际接轨甚至达到国际水平的大型品牌企业.
水龙头行业是与居民生活密切相关的行业. 作为 “主导问题” 加剧的, 这 “新国标” 应运而生. For the faucet industry that is expanding, 这 “未来” 的 “新国标” will obviously usher in a new industrial pattern.
思维: 您对新国标有何看法?
这 “带领” 水龙头的设计感动了人们的心, and it has also moved the relevant national departments. 5月 6, 国家颁布了 “新国标” 对于铅中毒, 并计划12月实施 1. “从发布到实施, 过渡期非常紧迫. Some big-name companies have strong technical strength to meet the standard, 和 30 % 企业将面临一次行业洗牌。” Some experts bluntly said that the new national standard will involve changes in enterprise technology, and whether some enterprises can withstand the pressure remains to be determined.
“If the new national standard is strictly implemented, 所有水龙头公司都将不得不倒闭. The new national standard obviously cannot be implemented in the near future.” The person in charge of an enterprise in Kaiping, 广东告诉记者,国家制定新国标是好事, 但可能不符合当前产业发展形势. 能否严格执行取决于各方利益, 且能否实施还有待证实.
的制定 “新国标” 可以说引起了业界的高度关注. The reason is that the new national standard “散步” ahead of the development of the industry.
