Abstract : by utlizing abundant local resource of ytirium and combining the characteristics of magnesium, barium, calcium and silicon, a sort of composite nodulizer - ytirium - based heavy rare earth nodulizer was developed which is characterized by its good desulphurizing and deoxidizing rate effect, excellent effect to neutralize anti - nodulizing effect of trace elements, strong nodulizng effect and degeneration - resistance, good effect to fine matrix structure, decreased chilling tendency and wide scope of applicatiom using this nodulizer to produce some important castings such as water - cooled wall of blast furnace and roller could increase mechanical properties of central area and casting yield
文摘:利用江西省豐富的釔基重稀土，結合鎂、鋇、硅、鈣等元素的特性開發了釔基重稀土復合球化劑，該球化劑具有脫硫、脫氧、抗干擾元素、球化和抗球化衰退能力強，細化基體組織，白口傾向小，適用范圍寬等特點，應用於高爐冷卻壁，軋輥等關鍵鑄件上可提高心部力學性能和工藝出品率。This paper unfolds engineering disposition and theoretical research of negative temperature high performance concrete ( nthpc ) with the damage of many factors motivation, the project background based on qing - zang railway engineering, which is one of four - emphasized engineering during the tenth five - plan. due to the difference of environment of construction and service between nthpc and ordinary concrete, and therefore durability of nthpc is required to higher level. at a first, nthpc must avoid frozen damage at early age and possess anti - freezing property at later period, in order to meet engineering practicable application need, and this are two emphasized and difficult problems, as for nthpc ; by means of mechanism analysis about deicing - agent ingredient and anti - freezing at early period, adopting composite technique routine of mineral addition + anti - freezing element + water - reducer4 - air - entraining + anti - erosion of steel component etc, based on orthogonal experimental approach, fd - 1 composite functional admixtu re was manufactured, which has more property and orientation on qing - zang railway
負溫混凝土由於和普通混凝土在施工環境及服役環境上存在的差異，因此表現為比普通混凝土更為較高的耐久性要求；負溫混凝土首先要避免早期的凍害以及具備長期抗凍性能，才能夠滿足工程實際應用的要求，這也是負溫混凝土必須解決的兩大技術關鍵；通過對目前常用防凍劑組分作用機理的分析研究及混凝土早期防凍機理探討，採用礦物外加劑+防凍組分+高效減水劑+引氣+阻銹組分功能復合的技術路線，通過正交試驗設計復配了適應青藏鐵路工程要求的專用多功能復合型外加劑fd - 1 ；並在此基礎上配製不同等級負溫高性能混凝土，開展一系列包括硫酸鹽侵蝕、氯離子滲透、抗凍融循環、收縮及耐磨性等耐久性能研究；通過對fd - 1組分和摻量的調整，優化負溫混凝土在施工特性、力學指標和耐久性三個方面的兼容、協調性。The results of lauryl sodium sulfate - polyacrylamide gel electrophoreses ( sds - page ) of the aggregate precipitate and supernatant and the result of high - performance size - exclusion chromatography of the supernatant indicated that, by wrongly linked intermolecular disulfide bonds soluble bi - molecular and tri - molecular egg white lysozyme aggregate could be simultaneously formed except being renatured to native and active egg white lysozymes during the refolding procedure of denatured - reduced egg white lysozyme ; the aggregate precipitate could be further formed by the non - covalent bonds interaction between the soluble hi - molecular egg white lysozyme aggregates, and the soluble tri - molecular egg white lysozyme aggregate could still stay at the supernatant
沉澱和上清液的不連續十二烷基硫酸鈉聚丙烯酰胺凝膠電泳（ sds - page ）和高效凝膠排阻層析分析結果表明，還原脲變性蛋白溶菌酶在稀釋復性過程中除了能夠復性成天然態蛋白溶菌酶分子外，還會形成可溶的蛋白溶菌酶分子二聚體和三聚體，二聚體和三聚體主要是靠分子間二硫鍵的錯配連接而成的；可溶的蛋白溶菌酶分子二聚體之間通過非共價鍵相互作用而形成集聚體沉澱，而可溶的三聚體溶菌酶分子則仍處于復性液上清液中。
