束纖維強(qiáng)伸度儀Stelometer
發(fā)布時(shí)間:2009-05-20
該儀器主要根據(jù)力矩平衡測(cè)力原理。 當(dāng)束纖維斷裂時(shí)利用擺錘傾斜角度對(duì)試樣施加的負(fù)荷表示最終的斷裂強(qiáng)力,還利用左右兩夾片間伸長(zhǎng)的距離表示纖維的伸長(zhǎng)率。每完成一次實(shí)驗(yàn),即可從兩標(biāo)尺上讀出拉斷該纖維所需的強(qiáng)力和斷裂瞬間的伸長(zhǎng)率。該儀器測(cè)試精度高,與成紗強(qiáng)力相關(guān)性好,纖維斷裂后,不會(huì)出現(xiàn)慣性誤動(dòng)作。(儀器指標(biāo)符合ISO3060-1974及GB/T13783-1992)主要性能指標(biāo): 1, 試樣夾頭總厚度:11.8mm 2, 隔距片厚度:3.2mm 3, 測(cè)量范圍:斷裂負(fù)荷20N-70N,伸長(zhǎng)率0-50%(3.2mm) 4, 加載速率:10N/s, 可調(diào) 5, 比強(qiáng)度修正系數(shù):不超出0.9-1.1的范圍(在溫度20±2℃,相對(duì)濕度(65±3)%條件下) 6, 體積:320 x 390 x 160mm 7, 凈重:10kg Stelometer KX154 An instrument to check the holding strength and elongation at breakage of fibre tufts. Holding strength reading on a graduated scale from 0 to 7 Kpa (step 0.1 Kpa), elongation reading on a graduated scale from 0% to 50%. This instrument can give accurate test results and is also easy to operate. It is built in accordance with ISO3060-1974 and GB/T13783-1992) Specifications: 1. Thickness of sample holding clamp: 11.8mm 2. Thickness of separator: 3.2mm 3. Test Range: Breaking Load 20N-70N, Elongation 0-50% (3.2mm) 4. Applying load speed: 10N/s, adjustable 5. Correction Coefficient (approxi.) 0.9-1.1 (tempreture be 20±2℃, relative humidity be (65±3)%) 6. Dimension: 320 x 390 x 160mm 7. Net Weight: 10kg
