初粘性試驗機Initial Viscosity Tester

設計標準：GB/T4852 ,CNS11888  (A法)

          GB/T4852,PSTC-7     (B法)

用途：膠帶初粘性滾球試驗機分為A法和B法兩種機型，適用于壓敏膠粘帶的初粘性測試。

A法：將不同大小之鋼球在斜面上滾動100mm在接觸膠帶，利用膠帶之粘著特性，鋼球停止記錄鋼球之號數及在膠帶上之距離來判斷其初始粘性。

B法：提供一個固定角度之鋼球助軌跑道，再利用規定尺寸鋼球被膠帶粘住前所滾過之距離，來判斷膠帶之初期粘性。

 Use: This BALL TESTER have A , B two kinds of machine, which applicable to pressure sensitive adhesive tapes of initial adhesion test.

    Method A:Let different size of the ball rolling 100mm on the slant then contact the tape , using the features of adhesive tape and the stop records of the steel ball’s numbers and the distance from the tape to determine its initial viscosity.

    Method B:To provide a fixed angle of the steel ball‘srun-up track, re-use the measurement steel ball’s rolling distance before it sticked by the tape to determine the initial sticky tape.
