彈性膨脹聚四氟乙烯密封帶上經過獨特加工製造而成的最以新穎的密封材料，是用純聚四氟乙烯製成，因此它保留了聚四性氟乙烯所具有一切優良性能，同時還具有極好的柔韌性和很高的抗拉強度等可貴特性，是中低溫度部位理想的密封材料。The results show that, with the quenching temperature ( 270 ~ 380 ) increasing, the carbon content and percentage content of retained austenite increase first and then decrease, which are up to a maximum value at 360 ; the tensile strength of adi decreases ; the elongation and impact ductility of adi increase first and then decrease, which are up to a maximum value at 360 ; but the hardness of adi decreases first and then increases, which is up to a minimum value at 360
結果表明，在試驗溫度范圍內（ 270 ~ 380 ） ，試樣中殘余奧氏體的含碳量及其含量隨著等溫淬火溫度的升高先增大后減小，均在360等溫淬火時出現最大值；抗拉強度隨著等溫淬火溫度的升高而逐漸降低；伸長率和沖擊韌度隨著等溫淬火溫度的升高先增大后減小，在360等溫淬火時出現最大值；硬度則隨著等溫淬火溫度的升高先減小后增大，當360溫淬火時硬度最低。From the experiments, we can see the affect of concrete performances mixing with liter polypropylene fiber and glass fiber is minor. compare with common concrete, the crack - load of concrete slab mixing with liter polypropylene fiber and glass fiber is marked improved. mixing with liter polypropylene fiber and glass fiber, the behavior of cracks - resisting of is marked improved, and the cracks are controlled and smeller
研究表明，在混凝土中摻入低摻量的聚丙烯纖維或玻璃纖維對抗壓強度及抗拉強度的影響較小；纖維混凝土板比普通混凝土板的開裂荷載有較為顯著的提高；加入低摻量的聚丙烯纖維后，混凝土板的抗塑性開裂性能有顯著提高，可以抑制、細化裂縫。Although cold - formed rectangular tube - steel column is favorable to industrialization of mass production, the cold forming process increase the yield point and tensile strength, at the same time the cold forming process decrease the ductile behavior, so it ’ s necessary to research the seismic behavior of cold - formed rectangular tube - steel column for architecture structure
冷彎矩形鋼管雖然可以實現大批量工廠化生產，但冷彎矩形鋼管在冷成型過程提高了材料的屈服點和抗拉強度同時降低了延性，因而冷彎矩形鋼管作為柱材在建築結構抗震中的應用有待進一步研究。Based on calculation method on unfold size and piece form, theory analysis and research are given on ellipse, circle tube, box as equal - high, irregular, unequal - high, irregular piece, process and condition on possibility of drawing are introduced, through calculation coefficient, number of drawing, drawing testing dies are made, results are given, it is similar to calculation method, in the same time, complex drawing presswork is planed, to avoid wrinkle, critical in drawing process. in this paper, die designing is introduced based on complex drawing unfold size calculation, press center is automatic calculated, apartments of press tools are calculated too with material mechanic production process and press form are better, period of die designing is to reduced, and cost of product is lower
對基於復雜拉深件展開尺寸計算的模具設計也作了詳細的論述，指出了現有復雜拉深件模具設計製造程序的不合理性，本文在復雜拉深件展開尺寸基礎上自動生成沖裁中心、沖裁周長，運用材料力學中桿件強度及抗失穩條件，實現對沖壓模具參數的自動計算，簡化了沖壓模具彈性元件、打料裝置的設計過程，給出了沖壓模具結構設計流程，使得模具材料核算，製造過程，沖壓方式更趨合理，縮短了模具設計製造周期，降低了產品生產成本。分享友人
