Description
本發明系關於一種環保抗鋅氧化黃銅合金配方及其製造方法；特別關於一種具有與習知含鉛或砷黃銅相當之機械加工性能，良好的抗拉強度及伸長率，極適合作為取代含鉛或砷黃銅合金之配方及其製造方法的創新發明。 The invention relates to an environmentally-friendly anti-zinc oxide brass alloy formulation and a manufacturing method thereof; in particular, a mechanical processing property equivalent to a conventional lead-containing or arsenic-containing brass, good tensile strength and elongation, and is very suitable as a substitute An innovative invention of a formulation containing lead or arsenic brass alloy and a method for its manufacture.
一般作為加工用的黃銅，會添加鋅金屬的比例為38至42%。為了讓黃銅更好加工，黃銅裡面通常有2~8%的鉛或砷以增加強度與加工性。含鉛或砷黃銅具有優良成形性(容易製作各種形狀產品)、切削性和耐磨耗性被廣泛應用於各種形狀的機械加工零件，在市場被廣泛使用，是世界上公認的重要銅合金基礎材料。但是，含鉛或砷黃銅在生產或使用過程中，容易發生鉛或砷以固態或氣態的形式釋出或溶出，醫學研究指出，鉛對人體造血和神經系統特別是兒童的腎臟及其他器官的損害較大。世界各國均很重視鉛或砷造成的污染和引起的危害，因而美國國家衛生基金(National Sanitatio n Foundation，NSF)及歐盟的危害性物質限制指令(Restriction of Hazardous Substances Directive，RoHS)等都相繼規定，限制和禁止含高鉛黃銅的使用。 Generally, as a processing brass, the proportion of zinc metal added is 38 to 42%. In order to make brass better processed, there is usually 2 to 8% lead or arsenium in brass to increase strength and processability. Lead- or arsenic-containing brass has excellent formability (it is easy to manufacture various shapes), machinability and wear resistance are widely used in various shapes of machined parts, and are widely used in the market, and are recognized as important copper alloys in the world. Basic materials. However, lead or arsenic brass is prone to release or dissolution of lead or arsenic in solid or gaseous form during production or use. Medical research indicates that lead is harmful to human hematopoiesis and the nervous system, especially children's kidneys and other organs. The damage is greater. All countries in the world attach great importance to the pollution and harm caused by lead or arsenic. Therefore, the National Sanitatio n Foundation (NSF) and the European Union's Restriction of Hazardous Substances Directive (RoHS) have successively provided , restricts and prohibits the use of high lead brass.
2006年9月20日美國加州通過了一項新的管道類 產品法令AB1953法案(亦稱加州無鉛法案)，此法案已於2010年1月1日正式實施執行，舉凡用途為人體直接飲用或烹調使用供水裝置，皆受到AB1953的嚴格規範。影響所及，包含廚房用水龍頭、吧台龍頭、浴室臉盆用水龍頭、飲水機以及閥門、儀表等任何其他終端的供水裝置，不分商業用或是住宅用，只要是安裝用來配送人體消費用水的裝置，皆必須符合此法案所要求之鉛含量必須在0.25%以下的規範標準。依目前現有法規，無鉛毒釋出的標準為在管道及其配套設備中，原本鉛的含量不得超過8%，在水管及其配套設備中，鉛的含量不超過4%，即合乎規定。但AB1953法案對原有飲用水供水系統相關產品的「鉛」標準進行了調整，其採用加權濃度控制替代簡單濃度控制，規定產品內與水接觸的零件其鉛成份含量與個別占整個水道面積的百分比計算後之總合鉛含量必須在0.25%以下。 On September 20, 2006, California passed a new pipeline class. Product Act AB1953 Act (also known as the California Lead-Free Act), this Act was officially implemented on January 1, 2010, for the purpose of direct drinking or cooking water supply devices, are subject to strict regulations of AB1953. Influencing, including kitchen faucets, bar faucets, bathroom basin faucets, water dispensers, and water supply devices for valves, meters, and other terminals, for commercial or residential use, as long as they are installed for distribution of human consumption water The devices must comply with the specifications required by this Act to have a lead content of less than 0.25%. According to the current existing regulations, the standard for the release of lead-free poison is that in the pipeline and its ancillary equipment, the original lead content should not exceed 8%. In the water pipe and its ancillary equipment, the lead content should not exceed 4%, which is in line with the regulations. However, the AB1953 Act regulates the “lead” standard for products related to the original drinking water supply system. It uses weighted concentration control instead of simple concentration control to specify the lead content of the parts in contact with water in the product and the individual water channel area. The total lead content after the percentage calculation must be below 0.25%.
歐盟市場自2006年7月1日起實施RoHS綠色環保規範，針對各種電機電子設備中使用的各種材料，其鉛、汞、六價鉻的含量須低於0.1%(1000ppm)，鎘含量須低於0.01%(100ppm)。未達到上述標準的電氣電子設備將被禁止輸入歐盟市場。對銅合金(含快削黃銅)中的鉛含量，目前規定了含量小於4%的豁免條款。但隨著代替材料的開發及普及，將刪除該項例外條款。在例外豁免條款中的銅合金，鉛含量最高可以達4%，換成一般業者容易理解的說法，就是銅合金中的鉛含量最高為40000ppm以下，相較於符合排外條款的低鉛銅材料，完全符合RoHS標準，而鉛含量在100ppm以下的銅材料，一般即稱之為無鉛銅材。 The EU market has implemented RoHS green environmental protection regulations since July 1, 2006. For various materials used in various electrical and electronic equipment, the content of lead, mercury and hexavalent chromium must be less than 0.1% (1000ppm), and the cadmium content should be low. At 0.01% (100 ppm). Electrical and electronic equipment that does not meet the above criteria will be banned from entering the EU market. For lead content in copper alloys (including fast-cut brass), an exemption of less than 4% is currently specified. However, with the development and popularity of alternative materials, the exception clause will be deleted. The copper alloy in the exception exemption clause can have a lead content of up to 4%. It is easy to understand from the general practitioner that the lead content in the copper alloy is up to 40000ppm, compared to the low-lead copper material that meets the exclusion clause. Copper materials that are fully RoHS compliant and lead less than 100 ppm are generally referred to as lead-free copper.
