mso-hansi-font-family:"Times New Roman"">一、用途:
mso-hansi-font-family:"Times New Roman"">回彈儀標準鋼鉆是對混凝土,砂漿,磚等回彈儀進行校驗的檢驗工具。?
mso-hansi-font-family:"Times New Roman"">二、混凝土回彈儀鋼鉆概述:
mso-hansi-font-family:"Times New Roman"">回彈儀標準鋼鉆各部件由優(yōu)質(zhì)鋼及優(yōu)質(zhì)工具鋼制成。砧芯與砧體的配合面【莫氏錐度4 mso-hansi-font-family:"Times New Roman"">號】經(jīng)精細研磨而成,砧心面硬度為HRC58-62。?
mso-hansi-font-family:"Times New Roman"">三、使用方法:
mso-hansi-font-family:"Times New Roman"">回彈儀標準鋼鉆一般放置在水平面上校驗回彈儀,回彈儀垂直向下作彈擊實驗,校準回彈儀的率定值。混泥土回彈儀在本剛砧上作彈擊實驗? "Times New Roman"">的平均率定回彈值為【N "Times New Roman"">】=80+2;砂漿回彈儀在本剛砧上作彈擊實驗的平均率定回彈值為【N mso-hansi-font-family:"Times New Roman"">】=74+2 "Times New Roman"">。
mso-hansi-font-family:"Times New Roman"">四、混凝土回彈儀鋼鉆注意事項:
mso-hansi-font-family:"Times New Roman"">回彈儀標準鋼鉆作為檢驗工具,被彈擊試驗5000 mso-hansi-font-family:"Times New Roman"">次-8000 "Times New Roman"">次后,可將砧芯連同砧體在平面磨平整再用,但砧芯硬度仍需保持HRC58-62 "Times New Roman"">,否則不得再用。回彈儀標準鋼鉆HB-59 "Times New Roman"">。
mso-hansi-font-family:"Times New Roman"">五、存放:
mso-hansi-font-family:"Times New Roman"">鋼砧平時保存在干燥防塵處,以防銹蝕,彈擊試驗面不得隨意磕碰, mso-hansi-font-family:"Times New Roman"">以保證檢驗工具的標準狀態(tài)。
