鋼絲網(wǎng)規(guī)格及用途
英文名:steel wire mesh
鋼絲網(wǎng)是建筑防裂、墻體保溫必備的建材。鋼絲網(wǎng)是水泥砂漿基面的骨架,可以選用鋼絲粗為16-18號(hào)網(wǎng)格為20-25毫米的鋼絲網(wǎng)或鍍鋅鐵絲網(wǎng)。
常用金屬網(wǎng)有兩種:鋼板網(wǎng)(拉網(wǎng))和鋼絲網(wǎng)(編織網(wǎng))
鋼板網(wǎng)是1.2mm厚鋼板沖切開口,拉伸而成。強(qiáng)度大,結(jié)實(shí)耐用,可獨(dú)立釘鋼板網(wǎng)直接抹灰。
鋼絲網(wǎng)是用細(xì)鋼絲或者鍍鋅鐵絲編織成網(wǎng),有不同網(wǎng)眼密度、尺寸,單位是“目”。必須背后襯托(水泥板、墻體等)使用。
用于裝修有鋼板網(wǎng)、鋼絲網(wǎng),抹墻網(wǎng),水泥砂漿靠網(wǎng)眼背后擠出砂漿凝結(jié)后固定,要求水泥砂漿充分臥裹以保護(hù)金屬網(wǎng)不銹蝕,類似鋼筋混凝土的保護(hù)原理。其中,鋼板網(wǎng)在使用前都是刷防銹漆的。
鋼絲網(wǎng)的材質(zhì)進(jìn)一步的拓展,主要有:長規(guī)格的不銹鋼絲網(wǎng)(低鎳的,302,304,316,316L等),主要應(yīng)用于化工企業(yè)過濾使用;錳鋼鋼絲網(wǎng)(65錳,75錳等),主要應(yīng)用于水泥篩網(wǎng),帶有氧化性的篩選;45#鋼鋼絲網(wǎng),主要是普通篩網(wǎng)。熱鍍鋅鋼絲網(wǎng),主要用于建筑外墻外保溫

熱鍍鋅鋼絲網(wǎng)優(yōu)點(diǎn):防腐性能優(yōu)異,耐久性能好
抗拉強(qiáng)度高,整體性好
技術(shù)資料:工藝 - 熱鍍鋅鋼絲網(wǎng) 絲徑 mm 0.9±0.04
網(wǎng)孔大小 mm 12.7×12.7
焊點(diǎn)抗拉力 N >65
鍍鋅層 g/m2 ≥122
鋼絲網(wǎng)執(zhí)行標(biāo)準(zhǔn):ASTM A 740-1998 JG158-2004 QB/T3897-1999
外墻保溫網(wǎng)的品種有熱鍍鋅鋼絲網(wǎng),耐堿玻纖網(wǎng)格布等。
用途及效果:
外墻保溫網(wǎng)主要用于一般建筑外墻、現(xiàn)澆混凝土、高層住宅等,在保溫系統(tǒng)中起著重要的結(jié)構(gòu)作用,在施工時(shí)將熱鍍鋅鋼絲網(wǎng)架聚苯板置于將要澆注的外墻外模的內(nèi)側(cè),外保溫板和墻體一次成活,拆模后保溫板與墻體合二為一,因此節(jié)省了人力、時(shí)間以及安裝費(fèi)用。所選用的熱鍍鋅鋼絲網(wǎng)架聚苯板塊大、質(zhì)輕,易于施工,外飾面可用于面磚,操作簡單,冬季也可進(jìn)行施工。
