彎折儀#TCFS-8型彎折儀2022年產品主要功能有哪些@品牌新聞報道
,彎折儀,測厚儀,抗穿孔性儀,抗靜態(tài)荷載測定儀,加熱伸縮測定儀,持粘性測定儀據(jù)技術部12月31號10點09分透露:(/c149978/products/d.html)
YI、TCFS-8型彎折儀概括:TCFS-8型彎折儀根據(jù)12953,GB/18173 GB/T328之規(guī)范設計制作。用于防水卷材與防水涂料的低溫彎折試驗。
二、TCFS-8型彎折儀試驗方法:1、按GB12953的圖1表4裁取試件,將試件的迎水面朝外,彎曲180度,使50mm寬的邊緣重合;齊平;并固定。將彎折儀上下平板距離調節(jié)為卷材厚度的3倍。
2、儀器翻開,把兩塊試件平放在下平板上,重合的*邊朝向轉軸,且據(jù)轉軸20mm。在設定溫度下將彎折儀與試件*起放入低溫箱中,達到規(guī)定溫度后在此溫度下放置1h。然后在標準溫度下將上平板1s內壓下,達到所調間距位置,在此位置保持1s后將試件取出?;謴偷绞覝睾笥^察彎折處是否斷裂,或用6倍大放大鏡觀察試件彎折處有無裂紋。
三、TCFS-8型彎折儀高分子防水涂料:將試件在標準條件下放置2h后彎曲180度,使25mm寬的邊緣對齊,用訂書機將邊緣外固定,調整彎折儀的上平板與下平板的距離為試件厚度的3倍,然后將試件放在彎折儀的下平板上,試件重疊的*邊朝向彎折機軸。據(jù)轉軸中心約25mm 的彎折儀放入低溫箱中,再規(guī)定溫度下保持2后打開低溫箱,在1內將上平板壓下,保持1出試件并用8倍放大鏡觀察試件。
四、記錄試件表面有無裂痕或開裂現(xiàn)象。五、試驗完畢將彎折儀表面處理干凈擦涂防銹油脂以備下次使用。裝箱單 名稱 | 規(guī)格 | 數(shù)量 | 單位 |
