亚磷酸钠 meaning in English
sodium phosphite
Examples
- With the increasing of knac4h4o6 * 4h2o and naacehso ? ? 2h2o , the speed of plating was increasing when the concentration of them was low
镀液的ph值与次亚磷酸钠和硫酸钴的摩尔比对镀层成分、及相结构的影响较为显著。 - When the bath temperature is 90 and nah2po2 h2o concentration is more than 80g / l , wetting time prolongs instead and solderability decreases
镀液温度为90oc时，次亚磷酸钠用量超过809几后，润湿i时间反而增长，可焊性下降。 - When the bath temperature is at 70 and 801 : , wetting time of the deposits shortened as the nah2po2 h2o concentration increases , and solderability improves
镀液温度在70t和80 ’ c时，镀层润湿时间随次亚磷酸钠浓度的增加而缩短，可焊性提高。 - The experiments showed that these factors could increase the plating rate which the concentration of nah2 ? o2 " t ^ o , the ph and the temperature of electroless plating had been risen
实验表明：镀液ph值和施镀温度升高，次亚磷酸钠和缓冲剂浓度增加，镀速提高。 - If phosphorus was adequacy in composite powder , co - p alloy coating becomes non - crystalline . the quality of composite powder was better , and the stabilization of solution is improved with the increase of the ph from 9 . 5 to 11 . 0
硫酸钴浓度18 40g / l ，次亚磷酸钠浓度20 40g / l ，可以得到镀覆均匀、分散性好的复合粉末；增加其浓度，复合粉体的镀覆质量得以提高。
