Abstract
The invention discloses a formula of novel sound reel copper. High-purity cathode copper, tin ingots and zinc ingots are selected as raw materials. The molecular formula of the high-purity cathode copper is Cu-CATH-1, and in the high-purity cathode copper, the content of copper is not less than 99.9935% and the content of lead is not more than 0.0065%; in the tin ingot, the content of tin is not less than 99.99% and the content of lead is not more than 0.0035%; and in the zinc ingot, the content of zinc is not less than 99.995% and lead does not exist. In percent by weight, the formula includes 50%-70% of high-purity cathode copper, 0.7%-0.9% of tin, 0.5%-0.7% of manganese and the balance of zinc. The formula is simple and convenient to process and low in cost; detected by China's Shanghai detection mechanism of German SGS (Societe Generale de Surveillance) well-known in the filed and referring to the specification in American Consumer Product Safety Improvement Act of 2008, the content of lead in the sound reel copper is allowed to be below 0.03%. By actual detection, the content of lead in the sound reel copper produced by the formula is 0.0034% and achieves the specified standard value.
Description
Technical field: the present invention relates to the material prescription that each kind musical instrument manufacturer produces required musical instrument copper strip special, particularly relate to the prescription of novel reed copper.
Technical background: musical instrument is the special implement of people's rich cultural entertainment life, and is just selected by numerous specialties and layman, and people all can feel pleased to use one or more musical instruments.And the core of musical instrument mainly is the musical instrument copper that can produce beautiful music.Traditional musical instrument copper all contains lead, and the plumbous amount of content is about 0.4%, and lead is toxic substance.Do not encroached on for the health of guaranteeing the musical instrument user, started with,, produced the numerical value that meets German SGS feeler mechanism regulation through experiment many times from material prescription.Originally this of domestic production kind of reed material is as from state's imports such as Japan, West Europe, and the reed material that price is produced than our company is expensive to be gone out more than five times.
Summary of the invention: purpose of the present invention is exactly the prescription that a kind of novel reed copper will be provided, thereby effectively controls lead content, has reached the standard figures of art-recognized German SGS feeler mechanism defined.The object of the present invention is achieved like this, the prescription of novel reed copper, and it is characterized in that: starting material are chosen as Cu-CATH-1, and molecular formula is Cu-CATH-1, and copper content is not less than 99.9935%, and lead content is not more than 0.0065%; Tin slab, tin content is not less than 99.99%, and lead content is not more than 0.0035%; Zinc ingot metal, zinc content is not less than 99.995%, and is unleaded; The weight percent prescription is: Cu-CATH-1 50%-70%, and tin 0.7%-0.9%, manganese 0.5%-0.7%, surplus is a zinc; The reinforced melting of order in accordance with regulations in 300Kg low frequency core-type induction furnace is by formulating processes.The present invention processes simply, makes things convenient for, cost is low, living Chinese Shanghai feeler mechanism through art-recognized German SGS detects, and improve bill with reference to the U.S.'s 2008 consumer's goods and stipulate, allow reed copper lead tolerance below 0.03%, the reed copper lead tolerance actual measurement that the present invention produces is 0.0034%, has reached the standard figures of defined.
Embodiment:
The prescription of novel reed copper, it is characterized in that: starting material are chosen as Cu-CATH-1, and molecular formula is Cu-CATH-1, and copper content is not less than 99.9935%, and lead content is not more than 0.0065%; Tin slab, tin content is not less than 99.99%, and lead content is not more than 0.0035%; Zinc ingot metal, zinc content is not less than 99.995%, and is unleaded; The weight percent prescription is: Cu-CATH-1 50%-70%, and tin 0.7%-0.9%, manganese 0.5%-0.7%, surplus is a zinc; The reinforced melting of order in accordance with regulations in 300Kg low frequency core-type induction furnace is by formulating processes.During concrete enforcement, starting material of the present invention are chosen as: Cu-CATH-1, molecular formula are Cu-CATH-1, and copper content is not less than 99.9935%, and lead content is not more than 0.0065%; Tin slab, tin content is not less than 99.99%, and lead content is not more than 0.0035%; Zinc ingot metal, zinc content is not less than 99.995%, and is unleaded; Manganese 0.6%; The weight percent prescription is: Cu-CATH-1 60%, and tin 0.8%, manganese 0.6%, surplus is a zinc; Strict this prescription of pressing in 300Kg low frequency core-type induction furnace, feeds intake in proper order by copper, zinc, tin, manganese, and fully stir-melting is pressed and formulated processes.
