220Z PPO旭化成

220z ppo旭化成--ppo在通讯器材该行业在国外以前是mp2po铝合金的较大销售市场,1985年占mppo 总需要量的42% ,现阶段已减少到21 %。ppo/hips关键作为外壳、机罩和机套,作为其他輔助组件的偏少。在通讯器材行业,关键用以手机、catv、通讯卫星园盘无线天线和pbx系统软件。虽然80 时代中后期因为其他原材料的市场竞争使ppo的市场需求降低,但来源于pc机和通信设备的强悍要求,仍在90时代中后期推动了mppo 消耗量的提高.通讯器材/办公用品对ppo的需求量将持续保持每一年5 %的增速

ppo was once the largest market for mp2po alloy in the unitedstates in the field of telecommunications. it accounted for 42% ofthe total demand of mppo in 1985 and has been reduced to 21% atpresent. ppo / hips is mainly used as casing, hood and casing, andless as other auxiliary parts. in the field of telecommunications,it is mainly used for mobile phones, catv, satellite disk antennaand pbx system. although the market share of ppo decreased due tothe competition of other materials in the late 1980s, the strongdemand from personal computers and communication e stillled to the growth of mppo consumption in the mid-1990s. the demandfor ppo from telecommunications / office e will continue tomaintain an annual growth rate of 5%
