4、傳統(tǒng)的灰鑄鐵管由于材料脆，強(qiáng)度和韌性較低，使用機(jī)械接口，不能承受更高的使用內(nèi)部和外部負(fù)載，使用時(shí)無法承受較高的內(nèi)、外載荷，經(jīng)常不可避免地發(fā)生爆、豁、斷、裂等現(xiàn)象，遇到地質(zhì)條件、外載條件變化時(shí)，容易發(fā)生管體脆斷、錯(cuò)位事故，并產(chǎn)生泄漏，現(xiàn)在已基本退出市場(chǎng)。 </p> <p> 5、水泥管可以提供大口徑的產(chǎn)品，但運(yùn)輸和安全的高成本，目前只在低經(jīng)濟(jì)水平地區(qū)使用。 </p> <p> 6、而鋼管耐蝕性差，使用壽命短，施工項(xiàng)目相對(duì)復(fù)雜，成本高，也逐漸退出了供水管網(wǎng)市場(chǎng)。 </p><p> VonWogozenKuhr等人在1974年提出了經(jīng)典的去極化理論，認(rèn)為埋地鑄鐵管的點(diǎn)蝕是由于SBR的活動(dòng)通過氫化酶將金屬表面去氧，總反應(yīng)式如下。4Fe+SO42-+4H2O3Fe（OH）2+FeS+2OH-好氧菌為鐵氧化菌，硫化菌和鐵，通過硫的作用產(chǎn)生硫酸可以發(fā)生好氧腐蝕。 </p> <p>

在水冷金屬型離心鑄造工藝中，應(yīng)防止過高的澆鑄轉(zhuǎn)速，調(diào)整適宜的翻包速度和主機(jī)走速;確保管模的打點(diǎn)的深度為0.25-0.3mm、直徑為4-5mm、點(diǎn)與點(diǎn)邊緣間距為0.5-0.7mm。 </p> <p> <br /> 廣西DN500球墨鑄鐵管批發(fā)價(jià)格量大價(jià)優(yōu)
