Description

TARIFNAME Düsük Kursun Oranina Sahip Bor Ilaveli Pirinç Alasimi TEKNIK ALAN Bulus, düsük kursun oranina sahip bir pirinç alasimi ile ilgilidir. TEKNIGIN BILINEN DURUMU Bakirin elektriksel iletkenligi yüksek seviyedir ve ayni zaman çevre dostu bir malzemedir. Ayrica bakir yüzeyinde zararli bakteriler hayatta kalamaz. Bakirin içerisine performansinin artirilmasi için baska elementler eklenir. Örnegin bakir ve çinko içeren bir pirinç alasimina kursun eklenmesi pirincin kesme performansini önemli ölçüde artirir. Ancak kursun oraninin fazla olmasi insan sagligina ve ekolojik denge için yikici bir etkiye sahiptir. Bu yüzden kursun içeren alasimlarin kullanilmasinda dünya çapinda kisitlamalar uygulanmaktadir. Genellikle, pirincin islenmesi daha kolay islenmesi için % 38-42 oraninda metalik çinko eklenir. Pirinç için dayanikliligini ve islenebilirligini artirmak için % 2-3 agirlik oraninda kursun ilave edilr. Kursun içeren pirinç mükemmel kaliplanabilirlige (çesitli sekillerde ürünlerin üretilmesini kolaylastirir), kesme performansina ve asinma direncine sahiptir, böylece çesitli sekillere sahip mekanik parçalara yaygin olarak uygulanir, bakir endüstrisinde büyük bir orana sahiptir ve dünyanin en önemli temel malzemelerinden biri olarak bilinir. Bununla birlikte, kursun içeren pirinç üretimi veya kullanimi sirasinda, kursun kati veya gaz durumunda çözülme egilimindedir. Tibbi çalismalar, kursunun insan hematopoietik ve sinir sistemlerine, özellikle çocuk böbreklerine ve diger organlara önemli zararlar verebilecegini göstermistir Bu nedenle, pirincin yüksek kursun içerigi alternatifi olacak, akiciligi iyi ve ayrica mükemmel döküm performansina, polisajlanabilirlik kalitesine, kesme performansina ve mekanik özelliklere sahip olan yukaridaki problemleri çözmek için bir alasim formülü saglamaya ihtiyaç EP2963134B1 yayini asagidakileri içeren bir düsük-kursun pirinç alasimina iliskindir: pirinç dengeleyici olarak kalan oranda çinko içermesinden bahsetmektedir. BULUSUN KISA AÇIKLAMASI Bulusun amaci, insan sagligi konusundaki kursunun toksit etkisini en aza indirmek için alasimdan kursunun çikarilmasi zorunlulugunu getiren yeni kanunlara uyum ile birlikte akiciligi iyilestirilmis, dökülebilirligi arttirilmis, mekanik özellikleri ve polisajlanabilirlik kalitesi iyilestirilmis bir pirinç alasimi saglamaktir. Bahsedilen amaçlara ulasmak üzere bulus, % 55 ila % 65 agirlik oraninda bakir; % 0.0001 agirlik oraninda demir içeren; % 0.01 ila % 0.3 agirlik oraninda kalay; % 0.1 ila % 0.4 agirlik oraninda alüminyum, % 0.0001 ila % 0.02 agirlik oraninda nikel içeren bir pirinç alasimi olup özelligi; %35 ila %45 agirlik oraninda çinko içermesidir. Bulusun tercih edilen bir yapilanmasinda, % 57 ila % 62 agirlik oraninda bakir içermesi ile karakterize edilmektedir. Pirinç alasimindaki bakir oraninin belirtilen degerler arasinda seçilmesi üretim verimliligi-yapisal özellikler-dayanim açisindan avantaj saglamakta ve ayrica elektrik iletkenligi kullanim yerine göre kabul edilebilir seviyelere gelmekte, ve buna ek olarak kolay dökülebilir bir malzeme olmasi nedeniyle de tercih edilmektedir. Bulusun tercih edilen bir yapilanmasinda, % 0.05 ila % 0.3 agirlik oraninda demir içermesi ile karakterize edilmektedir. Pirinç alasiminda demir, bor ile kombinasyon yaparak tane inceltmede rol oynar. içermesi ile karakterize edilmektedir. Pirinç alasiminda bor, demir ile kombinasyon yaparak tane inceltmede rol oynar. Bulusun tercih edilen bir yapilanmasinda, % 0.05 ila % 0.15 agirlik oraninda kalay içermesi ile karakterize edilmektedir. Pirinç alasiminin kullanim alanlarina göre mukavemet ve korozyon direncinin artirilmasi gerekmektedir. Bu yüzden pirinç alasimina kalay eklenmesi ile pirincin mukavemet ve korozyon direncinin artirilmasi saglanmaktadir. Bulusun tercih edilen bir yapilanmasinda; % 0.15 ila % 0.3 agirlik oraninda alüminyum içermesi ile karakterize edilmektedir. Pirinç alasimin dökülebilirligini arttirmak için ilave edilir. Bununla birlikte mukavemet ve sertlik degerleri üzerinde artis yönünde etkisi vardir. Bulusun tercih edilen bir yapilanmasinda, %36 ila % 44 agirlik oraninda çinko içermesi ile karakterize edilmektedir. Alasima çinko ilavesi ile pirinç alasimi olusmaktadir. Belirtilen % agirlik oraninda dökülebilirlik ve dayanim üzerinde olumlu etki yaratmaktadir. Bulusun tercih edilen bir yapilanmasinda, %37 ila %43 agirlik oraninda çinko içermesi ile karakterize edilmektedir. Alasimdaki çinko oraninin belirtilen agirlik oraninda olmasi dökülebilirlik, dayanim optimizasyonunu özelliklerinin iyilesmesini saglamaktadir. Bulusun tercih edilen bir yapilanmasinda, bor agirlik oraninin demir-nikel toplam agirlik oranina göre oraninin % 0.002 ila % 0.2 olmasi ile karakterize edilmektedir. Böylece, bor, pirinç alasiminin tane inceltilmesinde demir-nikel kombinasyonlariyla rol oynar. Akicilik, dökülebilirligi arttirabilir. Demir, pirinç alasiminin toklugunu artirabilir. Bulusun tercih edilen bir yapilanmasinda, bor agirlik oraninin demir-nikel toplam agirlik oranina göre oraninin % 0.0025 ila % 0.12 olmasi ile karakterize edilmektedir. BULUSUN DETAYLI AÇIKLAMASI Bu detayli açiklamada, bulus konusu gelistirme herhangi bir kisitlama olmayacak sekilde ve sadece konuyu daha iyi anlatmasi için örneklere referanslarla anlatilmistir. Yüksek kursun içerikli pirinçlere alternatif olarak kursunu azaltilmis, akiciligi iyi ve ayrica mükemmel döküm performansina, polisajlanabilirlik kalitesine, kesme performansina, Tatur testine ve mekanik özelliklere sahip olan yukaridaki problemleri çözmek için bir alasim formülü saglamaya ihtiyaç vardir. Formülasyon ile ilgili asagidaki tabloda verilen araliklarda seçilen element oranlarina göre pirinç alasiminin özellikleri detayli bir sekilde anlatilmistir.

TR TR TR DESCRIPTION Boron Added Brass Alloy with Low Lead Ratio TECHNICAL FIELD The invention relates to a brass alloy with a low lead ratio. KNOWN STATE OF THE ART Copper has a high electrical conductivity and is also an environmentally friendly material. Additionally, harmful bacteria cannot survive on the copper surface. Other elements are added to copper to increase its performance. For example, adding lead to a brass alloy containing copper and zinc significantly increases the cutting performance of the brass. However, high levels of lead have a devastating effect on human health and ecological balance. For this reason, worldwide restrictions are imposed on the use of lead-containing alloys. Generally, 38-42% metallic zinc is added to brass to make it easier to process. Lead is added to brass at a rate of 2-3% by weight to increase its durability and workability. Lead-containing brass has excellent moldability (making it easy to produce products of various shapes), cutting performance and wear resistance, so it is widely applied to mechanical parts of various shapes, has a large proportion in the copper industry, and is known as one of the most important basic materials in the world. However, during the production or use of lead-containing rice, lead tends to dissolve in its solid or gaseous state. Medical studies have shown that lead can cause significant harm to human hematopoietic and nervous systems, especially children's kidneys and other organs. Therefore, rice will be the high lead content alternative, which has good fluency and also has excellent casting performance, polishability quality, cutting performance and mechanical properties to overcome the above problems. need to provide an alloy formula to solve Publication EP2963134B1 relates to a low-lead brass alloy containing: brass mentions containing a residual zinc as a stabilizer.

Therefore, by adding tin to the brass alloy, the strength and corrosion resistance of brass is increased. In a preferred embodiment of the invention; It is characterized by containing 0.15% to 0.3% aluminum by weight. It is added to increase the castability of the brass alloy. However, it has an increasing effect on strength and hardness values. In a preferred embodiment of the invention, it is characterized by containing 36% to 44% zinc by weight. Brass alloy is formed by adding zinc to the alloy. It has a positive effect on castability and strength at the specified weight percentage. In a preferred embodiment of the invention, it is characterized by containing 37% to 43% zinc by weight.
