中文拼音 [fángróngjì]
防熔劑
英文
antiflux-
Antiwear ( aw ) agent additive that is active in preventing damage caused by occurrence of solid phase welding between sling surfaces without local surface melting
抗磨（ aw ）添加劑相互滑動的表面因發生相互摩擦會造成損壞。抗磨添加劑就是能有效防止這類磨損，同時又不會發生滑動的表面熔化的添加劑An strippable antirust packing plastic which was hot - melt type and solvent type was made of eva resin as the main film components, corrosion inhibitor and modifying agents, and the application of the material in the antirust of cutting tool and machine tool were discussed
摘要介紹了以熱塑性樹脂為主要成膜物質，加入防銹劑和改性劑製成熱熔型和溶劑型可剝離防銹包裝材料，並敘述了其在刀具和機床防銹方面的應用情況。The effect of h3bo3 was discussed in detail, and the luminescence and aferglow time was increased. the stability of this material was studied and it needs coating processing in application. then by changing the base, activator, flux and reaction condition, we studied different phosphors based on the aluminates, silicates, catio3 and y2o2s in detail, and obtained the best stoichiometry and preparation of these phosphors with the colors of red, red and orange, yellow - green, blue - green, cyan and blue - purple
本論文採用高溫固相法，對黃綠色sral _ 2o _ 4 ； eu ， dy長余輝材料的發光特性進行了深入的研究，詳細討論了助熔劑硼酸對材料的影響，大幅度提高了該材料的余輝亮度和時間，並對該材料的穩定性進行了研究，得出使用時要進行包膜或其他防潮處理的結論。Meanwhile it retains evenness on lift force to prevent leakage of residue that is caused by installation clearance error or changes in welding criteria, flow off molten iron as well as break - over welding, so that the ideal fosion depth and finishment have been fulfilled
在需原動力的條件下，該機利用彈性夾角變化，隨著筒體轉動，使墊層焊劑始終緊貼筒體外側環向焊接區，並保持托力均勻防止因裝配間隙誤差或焊接規范變化而引起漏渣，鐵水下淌及焊穿現象，達到理想的熔深度和光潔度。This paper is mainly concerned about how to purify the industrial products of the antioxidant d and bht, how to determine their purities, determining their purities and the purities need to be more than 99 %. in order to attain this objective, the recrystalizing method is used to purify antioxidant d and antioxidant bht. the methods of high performance liquid chromatography ( hplc ) is used to determine the chemical composition of the antioxidant d and bht, it is qualitative analysis
本論文是以防老劑d與bht工業品為主要原料制備防老劑d與bht標準物質，首先進行了防老劑d與bht的提純和熔點的測定試驗，並通過實驗確定了防老劑d與bht重結晶提純工藝；然後設計區域熔融裝置，擬定操作規程和技術條件，通過用區域熔融法提純重結晶后的防老劑d和bht產品滿足標準物質的純度要求。Electromechanical components for electronic equipment. basic testing procedures and measuring methods. part 12 : soldering tests. section 6 : test 12f : sealing against flux and cleaning solvents in machine soldering
