消防帶 我有新說法
1839 0


消防帶又名水龍帶，是一種能承受一定液體壓力的管狀帶織物。按所用原料，可分為棉、芒麻、亞麻、合纖襯膠等消防帶；按耐壓大小，可分為普通型和高壓型消防帶（工作壓力大于10kg/cm）。

分類

消防帶又名水龍帶，是一種能承受一定液體壓力的管狀帶織物。按所用原料，可分為棉、芒麻、亞麻、合纖襯膠等消防帶；按耐壓大小，可分為普通型和高壓型消防帶（工作壓力大于10kg/cm）。

特點

高壓消防帶常用高強(qiáng)低伸型滌綸長絲為原料，用雙梭圓織機(jī)織成管坯，內(nèi)襯l～3mm厚的橡膠或?qū)⒐芘鲀?nèi)外涂一層較薄的高分子合成材料，使其具有能承受高壓且不滲漏、耐腐蝕、耐磨、輕便等特點。消防帶常用的公稱口徑有：φ65、φ80、φ90和φ100mm六種規(guī)格，每條定長為20m?？趶皆?00-150mm的用于低壓排水或供水。

原料

安全帶所用纖維，最多的是尼龍，其次是滌綸，常用機(jī)織法以2/2斜紋制得。近年來，為提高生產(chǎn)效率，針織機(jī)已被越來越多的使用，熱定型條件（張力、濕度、時間）對安全帶的力學(xué)性能有非常重要的影響，如低伸度的安全帶需在高張力下進(jìn)行處理等。
