【摘要】本文分析了雙向拉伸聚酰胺(尼龍)薄膜拉伸強(qiáng)度測(cè)定的不確定度,通過建立測(cè)量不確定度的數(shù)學(xué)模型,分析了拉力機(jī)測(cè)試不確定度、厚度測(cè)試不確定度、寬度測(cè)試不確定度、重復(fù)性測(cè)試不確定度等因素對(duì)于測(cè)量不確定度的影響,并對(duì)其進(jìn)行評(píng)定,研究表明重復(fù)性測(cè)試因素對(duì)于不確定度結(jié)果的影響最大。

【關(guān)鍵詞】不確定度;拉伸強(qiáng)度;評(píng)定

Abstract: Determination of the uncertainty of the tensile strength of biaxially oriented polyamide (nylon) film is analyzed. Through establishing a mathematical model of uncertainty,the impact of factors such as uncertainty in tensile testing, uncertainty in thickness testing, uncertainty in width testing, and uncertainty in repeatability testing on measurement uncertainty is analyzed and evaluated. The research shows that repeatability test make the greatest impact on the results of uncertainty.

Keywords: uncertainty; tensile strength; evaluation

0引言

雙向拉伸聚酰胺(尼龍)薄膜是生產(chǎn)各種復(fù)合食品包裝材料的重要材料,已成為繼雙向拉伸聚丙烯(BOPP)、雙向拉伸聚對(duì)苯二甲酸乙二醇酯(BOPET)薄膜之后的第三大包裝材料。(剩余3011字)
