,彎折儀,測(cè)厚儀,抗穿孔性儀,抗靜態(tài)荷載測(cè)定儀,加熱伸縮測(cè)定儀,持粘性測(cè)定儀據(jù)技術(shù)部12月31號(hào)10點(diǎn)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(shè)計(jì)制作。用于防水卷材與防水涂料的低溫彎折試驗(yàn)。
二、TCFS-8型彎折儀試驗(yàn)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(diào)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(zhuǎn)軸,且據(jù)轉(zhuǎn)軸20mm。在設(shè)定溫度下將彎折儀與試件*起放入低溫箱中,達(dá)到規(guī)定溫度后在此溫度下放置1h。然后在標(biāo)準(zhǔn)溫度下將上平板1s內(nèi)壓下,達(dá)到所調(diào)間距位置,在此位置保持1s后將試件取出?;謴?fù)到室溫后觀察彎折處是否斷裂,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(biāo)準(zhǔn)條件下放置2h后彎曲180度,使25mm寬的邊緣對(duì)齊,用訂書機(jī)將邊緣外固定,調(diào)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(jī)軸。據(jù)轉(zhuǎn)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(nèi)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(yàn)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 |
