1、http:/ htt p:/ p:/ 对于银补口和焊料成分含量你了解多少 For repairi ng and silver solder compositi on content is how much do you know 在的世界,科技不时开展,使人们的生死水平大幅度进步。人们 对饰品的外观、外型的请求,将会像对时装的需求一样。正由于如此, 新型贵金属饰品资料的开发研讨显得越来越重要,怎样使其可以消费 出外型更精致、颜色更丰厚、资料性能愈加稳定的饰品,以满足消费 In the world, from time to time to carry out the scie nee and
2、tech no logy, make peopi es life level greatlyimpro veme nt. Peoples appearanee, appearanee requests to act the role ofing is tasted, will like the demandfor fashion. Dueto this reason, the development of new preciousmetal jewelry materials research is more and more important, how to makeit can cons
3、ume out of sha pe, color is more rich, more and more refined data p erforma nee more stable accessories, to meet con sumer dema nd, is beco ming the research hots pot of this category. 这就使得我们有必要对现今在市场上存在的各种贵金属合金首 饰的成分和含量以及制造工艺做大量的研讨, 以求在充沛理解市场及 各种金属成分及其含量的变化所带来的贵金属合金各方面性质变化 的根底上,为我们开发出愈加美观, 合适人们佩带,并
4、有利于人们身 market 体安康的贵金属首饰奠定根底, 从而顺应日益开展的市场的需求。 Which makesit is necessary for us to nowexist in the all kinds of preciousmetal alloy jewelry as well as the comp ositi on and content of the manu facturi ng p rocess to do a and the lot of discussion,in order to full understand the market in all kinds of
5、 metal comp ositi on and its content cha nges brought about by the precious metal alloy various aspects warp and woof of n ature of cha nge, for us to devel op more and more beautiful, suitable for people to wear, and is beneficial to peoples physical well-being precious metal jewelry, lay the foun
6、dati on so as to comply with the dema nd of in creas in gly devel oping market. 银补口、焊料的制造加工工艺也在期间日臻成熟。 其中银补口是 为了能很好的处理银饰品的氧化、变黑、麻点、沙洞、断裂等问题而 在银料中填加的其他金属元素;而焊药是指在加工贵金属资料时所用 的衔接贵金属及其合金之连续口的一种与贵金属及其合金性质类似 Silver filling mouth, during the manufacturing process of the solder in mature gradually. Which th
7、e silver fill is in order to handle the oxidation of silver ornament, turning black, pitting, sandhole and fracture in the silver material to add other metal eleme nts; And flux ing age nt refers to the cohesi on of Preciousmetals and their alloys used in the processing of p recious metals data of t
8、he serial port of a similar alloy materials and precious metals and their alloys. Coating is made of all kinds of p recious metal alloy materials. 目前我们采用的主要是两种比拟常用的对银补口和焊料的成分 含量停止剖析的办法,首先是X射线荧光光谱剖析法-X射线荧光光 谱剖析法的基木原理是:以足够高能量的x射线光子轰击样品,从样 品原子中激起出能反映不同元素特征的独立的特征x射线。检测特征 x射线的波长(能量)及其强度,从而对样品停止定性和定量剖析。能
9、够用于贵金属成分及含量剖析办法的综合剖析。这次测试中所用x射 线荧光光谱剖析仪的型号为GY-I( D Currently we use mainiy two compared commoniy used for repairingand silver solder the component content of stop P rofili ngmethod, first the X-ray fluoresce neesp ectruman alysis method, X-ray fluoresce nee sp ectrum an alysis method in the base woo
10、de nprinciple is: with eno ugh high-e nergy X-ray p hot on bombardme nt sample, sam pie from atomic stirred out can of independent characteristics of x-rays. Detectio n of reflect the characteristics of the differentelements to characteristic X-ray wavelength (energy) and its intensity, stop the qua
11、litative andquantitativeanalysis of the sample. Can be used for metal components and content an alysis method ofcompr ehe nsive an alysis. X-ray fluoresce neesp ectrum analysis instrument used in the test model for GY - the I (D), the test temp erature to room temp erature. 另一种剖析办法是电子探针x射线显微剖析法-电子探针
12、x射线 显微剖析法的根本原理是:用高能微细的电子束轰击样品,使样品产 生特征的x射线,由此能够定性、定量的剖析样品微区的元素类型和 含量。其剖析微区的下限能够到达 ium剖析的元素能够从第11号 92号(NaU高型号的仪器能够剖析 592号元素)五角枫。由于 电子束映照面积很小,因此相应的x射线特征谱线将反映出该微小区 域内的元素品种及其含量。显然,电子探针将电子放大成像与x射线 衍射剖析分离起来,就能将所测微区的外形和物相剖析对应起来(微 区成分剖析),这是其最大的优点,本次所用电子探针x射线显微剖 析仪型号为JCXA-733,测试温度为20 C,湿度为60% Another analysi
13、s method is the electron probe x ray micro analysis method, electron probe x ray micro analysis method the fun dame ntal principle is: use high en ergy micro electr on beam bombardme nt sample, the sample x ray features, thus can be qualitative and quantitativeanalysis sampie micro area of the eleme
14、nt type and content. Lower limit can reach 1 um, it analyze the micro area an alysis of eleme nts can from 11th 92 (Na U, high model of this instrument is able to analyze the element number5 92). Dueto the electron beamreflected area is small, so the corresponding X-ray characteristic spectrallines
15、will reflecteleme nts varieties and contents of the small area. Obviously, electr on p robe to sep arate electro nicamp lificati on imaging and X-ray diffraction analysis, it can be measured in sha pe and match them with the p hysical p hase an alysis (micro component an alysis), which is the bigges
16、t adva ntage, electr on probe x ray micro analysis used in the device model for the JCXA -733, the test temp erature is 20 C , humidity is 60%. 在对常见的倒模用925银高温补口、倒模用925银中温补口、手 造用925银补口以及925银的焊料停止成分剖析后,由于在合金中参 加镍能够提升合金资料的延展性、熔点等性能,而在合金中参加铜和 锌能够增加合金的可铸性能,因而,今天我们所要讨论的925银的补 In com mon use 925 silver hig
17、h temp erature reverse mould repairing,reverse mould by removing in the 925 silver mouth, hand made with 925 silver repairing and 925 silver solder stop comp ositi on an alysis, due to p artic ip atein ni ckel in the alloy can improve the ductility of alloy materials, melt ing point, and zinc in all
18、oy can such as p erforma nee, and for copper in crease the alloy can be cast p erforma nee, therefore, what we are going to discuss today 925 silverrepairingmaterials except silver mainly touched the three metals: brass, zinc and n ickel. 倒模用925 Use 925 silver high temp erature reverse mould rep air
19、i ng. 用做倒模的高温交融925银的补口资料颜色为暗雪白色,用两种 Used for high temperature blend of reverse mould repairing data of 925 silver color as dark white, with two differentways to make the test results are as follows: 与市场上常见的含铜量为7.5%的银铜合金相比,这种倒模原料 的含铜量比拟低,不到其含铜量的一半。这是由于作为倒模原料,这 种资料是用于消费925银饰品的起版需求农用拖拉机。而锌对合金的 时效起着很重要的作用,参加锌能够使贵金属合金在热处置的条件下 硬化,来进步其硬度,使倒模愈加有形,而不会由于温渡过高或压力 过大而使其模子变形,因而,在925银高温倒模资料中参加了较高含 量的锌,为一切补口资料中最多的除渣机, 超越了补口资料总量的一 With common)n the market of silver copper alloy containing copper content of 7.5%, compared to the reverse mould material compare with low copper conten t, less tha
