Phosphor bronze plate has very good production and processing performance, and is often used in drilling production and processing into various spare parts products. Among them, the most widely used raw material of phosphor bronze plate in drilling production and processing is Pb-containing phosphor bronze plate (H59-1, etc. model phosphor bronze plate). Phosphor bronze plate with lead content has high-quality organic chemistry, physics, structural mechanics and easy-cutting properties, and is a more commonly used alloy copper raw material. According to the incomplete statistical analysis of the published data and information, the total output of lead-phosphor bronze plates in my country is about 2 million tons at this stage, which are mainly used in electronic devices, household appliances, hardware locks, connectors, software plumbing installation oil circuit boards, Smart water meters, flanges, and children's toys.
Lub hauv paus ntsiab lus ntawm kev txiav yooj yim ntawm cov hlau lead phosphor bronze phaj: Thaum lub sij hawm tsim cov txheej txheem, thaum cov khoom siv ntawm cov hlau lead phosphor bronze phaj yog drilled thiab ua tiav, cov diffuse Pb (lead) particles yog ib qho yooj yim rau tawg thiab ua rau kev tawg, uas nyob rau hauv lem ua. raws li slag thiab txo viscosity. Adhesion thiab vuam thiab lawv cov kev ua tau zoo hauv kev nce kev hla dhau. Vim qhov qis melting point ntawm cov hmoov txhuas nyob rau hauv cov khoom siv raw, thaum drilling, qhov sib cuag ntawm lub qhov txhab thiab cov nti melts instantly thaum rhuab, uas yog conducive rau hloov cov tsos ntawm drilling thiab muaj ib tug moisturizing nyhuv.
Raws li lub hauv paus ntsiab lus ntawm kev yooj yim- txiav kev ua tau zoo ntawm cov hlau lead phosphor bronze phaj, cov ntsiab lus uas muaj txiaj ntsig zoo rau kev txhim kho kev ua haujlwm ntawm cov hlau alloy tooj liab feem ntau muab faib ua peb hom raws li lawv muaj nyob rau hauv alloy tooj liab: thawj hom, ib qho me me ntawm cov khoom siv nyob rau hauv alloy tooj liab, thiab nrog tooj liab los tsim eutectic ntsiab (xws li: Pb, Bi, Ce, Te); qhov thib ob, insoluble hauv alloy tooj liab, tab sis nrog tooj liab los tsim cov tshuaj (xws li: S, O cov no); qhov thib peb, ib feem ntawm cov khoom sib tov alloy tooj liab, kuj nrog tooj liab los tsim cov tshuaj (xws li: P, Si, thiab lwm yam). Ntxiv cov khoom sib txawv yuav txhim kho cov khoom tsim thiab kev ua haujlwm, physics, thiab organic chemistry ntawm tooj liab alloys rau ntau qib.
Niaj hnub no, vim tias kev tswj hwm cov ntsiab lus ntawm cov hmoov txhuas tau dhau los ua nruj dua, ntau lub tebchaws yuav tshawb fawb txog kev tshawb fawb txog cov hlau lead tshiab -dawb, hnyav- hlau-dawb, dawb{{3} } txiav phosphor bronze daim hlau los hloov cov hlau lead phosphor bronze daim hlau, thiab ntau qhov kev tshawb fawb tshawb fawb tau tau txais.
