中文拼音 [chāodīwēnjiāo]
超低溫膠
英文
ultra-low temperature glue-
What happens to rubber when it ' s supercooled
橡膠在超低溫的環境下會怎麼樣？Mainly made of super - fine three - dimensional staple fibers and mixed with some polyester staples of low melting point and finished products scarcely containing glue materials. after being calenderized and ironed, the product get smooth surface, silk - like glittering effect, light and exquisite hand feeling, softness, heat preservation, good washing endurance, no distortion and leaking. it feels like down but with fine tenacity and is the best among all spray bond padding products
用超細三維中空短纖維為主要原料，配以部分低熔點滌綸短纖，成品含膠量極少，經過軋光燙平后，仿絲綿表面平整、有絲光、輕薄、手感細膩、柔軟、保溫好、耐水洗性極強、不易變形、不會跑毛、手感似羽絨，具有質地纖細、表面如蠶絲、有拉力、柔軟等特點，是噴膠棉中最高擋的產品。Abstract : this paper dicussed the preparative parameteres synthesized mullite ultrafine powder by sol - gel and co2 scfd ( supercritieal fluid drying ) method from teos and al ( no3 ) 3 ? 9h2o as raw materials. the control parameteres of the colloidal particle size forming in sol - gel process and the gel structure and the scfd were studied by, xrd, tem and bet techmiques
文摘:研究了以正硅酸乙酯和硝酸鋁為原料，採用溶膠一凝膠法結合co2超臨界流體低溫乾燥技術合成莫來石超細粉的制備參數控制，並利用xrd 、 tem和bet 、技術研究了溶膠-凝膠過程中溶膠膠粒大小的控制和凝膠結構的控制及超臨界流體乾燥技術的控制。If the manufacturing temperature exceeds 200c, the melt viscosity will increase sbs molecules may result in arching which reduce the productivity
若加工溫度超過200c ，熔膠粘度會上升sbs分子可能有架橋現象，因而降低生產率Polymer - network gel process was used to synthesize nanometer oxide such as zro2 ( 3. 5mol % cao ), co3o4 and nio. dta / tg, xrd and tem were used to characterize the gel and products, and determine the lowest temperature and time for calcining the gel. the effect of the concentration of starting solution, temperature and time for calcining the gel on the size of the products were also discussed
本文採用高分子網路凝膠法進行納米zro _ 2 （ 3 . 5mol cao ） 、 co _ 3o _ 4 、 nio等納米氧化物超細粉的軟化學合成，利用dta tg 、 xrd和tem等分析手段對凝膠和產物超細粉進行表徵，確定凝膠的最低煅燒溫度和煅燒時間，並探討起始無機鹽溶液濃度、凝膠的煅燒溫度和煅燒時間對產物超細粉粒徑的影響。The hexagonal barexfe, 2. xo, ( re denote la ^ nd > sm and gd ) ultrafine powders with m - type structure were firstly synthesized by a novel technique - - - - - - sol - gel combustion synthesis method which combines sol - gel method with low temperature combustion synthesis method. based on theoretical analysis and experimental study, the effects of the composition of the gel, the different kinds of intermediate, strength of solution, the amount of complexing agent, the different kinds of anions, the adding of dispersant, auto - propagating combustion and the condition in heat treatment of the gel on crystal phase, particle size, morphology and magnetic properties of bare ^ fe ^ o, ultrafine powders were firstly investigated systematically to clarify the optimum forming conditions
本研究是在前人工作的基礎上，同時從制備方法和摻雜元素兩方面著手，以保證制備的粉體材料具有優異的性能，即首次利用溶膠?凝膠濕化學合成法和低溫燃燒合成法相結合的一種兼具二者優點的超細粉末新型合成技術? ?溶膠-凝膠燃燒合成法來完成稀土元素摻雜鋇鐵氧體bare _ xfe _ （ 12 - x ） o _ （ 19 ） （ re為la 、 nd 、 sm 、 gd ）超細粉末的制備。分享友人
