中文拼音 [shāmóyìngdù]
砂模硬度
英文
mold hardness-
The pouring tests of the ladder foam sample were made in silica sand, chromite sand and zircon sand the results show that zircon sand and chromite sand have the better chilling effect, and the structure of the aluminum alloy is finer, the hardness and strength has large improvement, subsequently the investigation provides the reference for manufacturing aluminum alloy thin thickness mold with excellent quality
結果表明,鋯英砂和鉻鐵礦砂具有較好的激冷效果,得到的鋁合金鑄件組織細小,強度、硬度有較大的提高,為薄壁隨型、質量優異的鋁合金消失模模具製造提供了技術依據。The results of the experiment are as follows : the bend strength, bend modulus, stiffness and toughness of the mortar layer will be improved when add 30 % fsmf to resin. the axis tensile strength, stiffness, hardness and weariessness of winding layer will be improved when add 25 % ~ 30 % fsmf to resin
提出了應用設想並進行了實驗研究,結果表明:在樹脂中加入30 %的fsmf ,可提高夾砂層的彎曲強度、彎曲模量、剛度和韌性;在樹脂中加入25吠屍30 %的fsmf ,可提高纏繞層的軸向拉伸強度、剛度、硬度和耐磨性,降低成本。
