該試驗機采用精密機械結(jié)構(gòu)和自動化控制系統(tǒng)，能夠精確執(zhí)行標(biāo)準(zhǔn)化的測試流程。設(shè)備通常配備微電腦控制、觸摸屏操作界面和數(shù)據(jù)記錄系統(tǒng)，實現(xiàn)測試過程的高效管理和結(jié)果的可追溯性，滿足制藥行業(yè)對質(zhì)量控制的嚴(yán)格要求。
測試原理
GB/T8948抗揉搓性能試驗機的測試原理基于機械摩擦模擬法。測試時，將規(guī)定尺寸的試樣固定在儀器的兩個夾具之間，通過一個夾具的往復(fù)運動對試樣進(jìn)行揉搓作用。
夾具間的距離可調(diào)節(jié)，通常設(shè)置為35mm。在測試過程中，上夾具保持固定，下夾具以設(shè)定的頻率和行程進(jìn)行往復(fù)運動，使試樣受到持續(xù)的揉搓作用。揉搓頻率通常為120次/分鐘或45次/分鐘，根據(jù)不同標(biāo)準(zhǔn)和要求可選擇不同的測試模式。
測試過程中可施加不同的壓力負(fù)重，范圍通常為0.2-2.0kg，通過壓碼遞增加載的方式實現(xiàn)。測試結(jié)束后，通過檢查試樣表面的龜裂、損傷情況或測定其物理性能變化來評估材料的抗揉搓性能。
應(yīng)用領(lǐng)域
GB/T8948抗揉搓性能試驗機在多個行業(yè)的質(zhì)量控制與產(chǎn)品研發(fā)中具有重要應(yīng)用價值。
