    超声波清洗机清洗不锈钢眼镜架配件原理
    2016-8-23 14:19:04
    眼镜中不锈钢眼镜架与黄铜、白铜镜架相比具有耐腐蚀性强、强度高、弹性好、环保等优点。但在不锈钢的钎焊技术一点问题,主要表现为焊点表面少孔、脱焊、焊点氧化等。首先应重视焊前处理,其次还要注意不锈钢对不锈钢时的清洗细节处理。
    Compared with a glasses in stainless steel frames with brass, copper nickel alloy frame, high corrosion resistance, high strength, good elasticity, environmental and other advantages. But in a stainless steel brazing technology, mainly for the solder joint surface less holes, welding, solder joint oxidation etc.. First, we should pay attention to the pre welding process, and then we should pay attention to the stainless steel cleaning details of the treatment.
    没有经过超声波清洗机清洗处理的配件表面粘,粘有油污和氧化膜,严重影响钎料对金属表面的润湿和流散。眼镜架配件焊前必须经过冷却去油和清洗机清洗,采用(HNO3)10%(H2SO3)6%,HF50G/(水)84%的水溶液酸洗,温度和时间分别为20℃,10分钟。
    Not after ultrasonic cleaning machine cleaning accessories to stick on the surface is pasted with a grease and oxide film, seriously affect the solder on the metal surface wetting and diaspora. Glasses frame fittings before welding must be after cooling oil and cleaning machine, using (HNO3) and 10% (H2SO3) 6%, HF50G/ (water) 84% aqueous solution of acid, temperature and time respectively 20 DEG C, 10 minutes.
    酸洗后用60-80℃的热水清洗残液,并迅速在60-80摄氏度的热空气中干燥,尽量缩短存放时间,从速完成钎焊,防止二次污染。配件经过机械加工会产生内应力,使金属晶格发生扭曲,
    After pickling with 60-80 DEG C hot water cleaning residue, and quickly in the 60-80 degrees Celsius hot air drying, try to shorten the storage time, expeditiously completing the brazing, to prevent secondary pollution. Parts of the mechanical processing will produce internal stress, so that the metal crystal lattice distortion,
    甚至于可能引起晶格破裂,钎焊由于钎料作用可能产生应力腐蚀,造成钎焊接头不致密,所以配件焊前通常要经受退火处理和清洗机清洗,以便肖除压力,对于难钎焊、硬质合金钢而言,配件表面镀载舟覆金属是一项特殊的预处理工艺,这是为了改善钎焊质量。
    Even may cause lattice rupture, brazing solder may cause stress corrosion due to, resulting in brazed joint is compact, so before welding accessories usually subjected to annealing treatment and cleaning machine to Xiao except pressure, for hard brazing, hard alloy steel, accessories surface plating metal boat cover is a special pre treatment process, which is to improve the quality of brazing.
