Mullen C 頂破強(qiáng)度測試儀的運(yùn)作
不論您使用的型號是否手動或是全自動的操作型號,測試原則是相同的。
要測試的樣品材料夾緊在測試儀上兩個橫放扁平的圓板之間。 流體從一個腔室經(jīng)活塞恒定的移動率而流出,迫使一個沉重的橡膠膜擴(kuò)大至低盤 開口,并施加一個不斷提升的壓力對抗沒有支撐的樣品區(qū)域。在此同時,連接到氣缸的測量器表示的壓力在氣缸內(nèi)上升。瞬間樣品脹破,壓力 下降,讓壓力表指針靜止并指出把樣品脹破所需要的力。
脹破力量測試指出一種材料在受到瞬間沖擊的強(qiáng)度比較。測試可以指出機(jī)織物中經(jīng)紗和緯紗的相對強(qiáng)度,或針織面料中各纖維的強(qiáng)度比較。它表示紙或非織造布面料的纖維張力,并展示出實時或最終,物料使用的染料,化學(xué)品或所有類型材料加工,從瓦楞紙板到塑料薄膜的影響。 它顯示了磨損、老化和環(huán)境變化的對材料強(qiáng)度的影響。
MULLEN型號
對于200psi以下的壓力的有C型,LC型和CA型,主要用于,紙張,鋁箔,塑料,輕量紡織品,非織造布,針織物等材料上,所有型號的測試程序都是相同的,型號間不同的地方是在于自動化的程度上。
對于200PSI到1500PSI壓力,有A型和AH型測試紙板,瓦楞板,重量級紡織品等等,J型是使用500PSI壓力,在所有型號的測試程序都是相同的,型號間不同的地方是自動化程度。
