熔析鉛 的英文怎麼說
中文拼音 [róngxīqiān]
熔析鉛
英文
liquated lead-
Methods for chemical analysis of melted welding fluxes. the lead chlorofluoride - edta volumetric method for determination of calcium fluoride content
熔煉焊劑化學分析方法.氟氯化鉛- edta容量法測定氟化鈣量The imported transparent glaze fired at lower temperature was analysed semi - quantitatively by adopting emission spectroscope. the stripping of lead and cadmium from this transparent glaze fired at lower temperature in ceramic product was determined by atomic absorption spectroscope. the effect of chemical composition on the stripping of lead and cadmium was analysed. upon the author s opinion, the overproof lead stripping from the imported transparent glaze fired at lower temperature can only be settled by adopting lead - free glaze instead of adopting low - lead prescription. the author succeeded in developing an excellent lead - free transparent glaze fired at the lower temperature of 1000 1050. the success is based on an inquiry into the feasibility of using such new agents of fusion as li2o and sro in replacement of pbo ; and on a study of the effects of the contents of sio2 ， al2o3 ， b2o3and other metallic oxides on such performances of glaze as coefficient of linear expansion, fusion temperature and transparency. it is also based on an analysis of coefficient of linear expansion of blank and glaze on an analysis of coefficient of linear expansion of blank and glaze on their correlation ; and on a study of technology for preparing glaze
採用發射光譜儀對進口低溫透明釉進行半定量分析，並用原子吸收光譜儀測定其陶瓷製品的鉛、鎘的溶出量，分析化學成分對鉛、鎘溶出量的影響.結果表明，進口低溫透明釉採用低鉛配方不能解決鉛溶出量的超標問題，只有採用無鉛釉才能解決.探討用氧化鋰和氧化鍶等新型熔劑完全代替氧化鉛的工藝，研究釉料中氧化硅、氧化鋁、氧化硼和各種金屬氧化物的含量，對釉的線膨脹系數、熔融溫度和透明度等性能的影響.分析坯料、釉料的線膨脹系數及其相互關系和釉料制備的工藝，研製出優質的1000 1050低溫無鉛透明釉Abstract : the defects such as inclusion, splitting, dislocation and dendrite in the pbxla1 - x ( zry tiz sn1 - y - z ) o3 ( plzst ) single crystal grown from pbo - pbf2 flux by the slow cooling self - seeding technique were discussed in this paper. the forming mechanism of these defects were analyzed and some measures to eliminate the defects were proposed
