With the heart of the sincerity, be full of the fine love to treat each person, let nearby the ocean overflows the genuine feeling that its joy melt; 以真诚的心,满怀着美好的爱去对待每一个人,让身边洋溢着其乐融融的真情;
Cr-Al ( Cr) 2O3 cermets with fine Cr particles uniformly distributed in ceramic matrix have been successfully produced by combination of combustion synthesis and solidification technique of controlling the melt cooling condition. The cermets have relatively good oxidization resistance. 通过燃烧合成和控制熔体冷却条件的凝固技术合理结合,制备了Cr相颗粒细小均匀分布于陶瓷基体的Cr-A(lCr)2O3金属陶瓷,该金属陶瓷具有较好的抗高温氧化性能。
Results show that quantity of fine powder can be increased when the gas pressure and melt temperature are properly increased or the inner-diameter of melt delivery tube is reduced. 结果表明:适当地提高气体压力和金属熔体温度或者减小导液管内径,均能使雾化粉末细粉量增加。
In the fine POY and DTY's melt direct spinning, non-homogeneity of fibers 'supermolecular structure and dyeing were caused by chips of wide molecular weight, high melting crystallization temperature and narrow melting peak. 试验发现相对分子质量分布宽,熔融结晶温度高且切片熔融峰形窄,在直纺生产细旦POY、DTY时易造成纤维超分子结构的不匀,而产生染色不匀。
Au-Sn solder has large strength, fine ant-oxidation, small melt point, low liquidity, excellent heat fatigue and creep deformation resistant. 金锡焊料本身强度高,抗氧化性能好,抗热疲劳和蠕变性能优良,熔点低,流动性好。
