TPO(熱塑性聚烯烴)防水卷材機械固定施工<br />
TPO(熱塑性聚烯烴)防水卷材屋面系統一般采用機械固定。即卷材鋪設于基層(或已被固定的保溫板),在相鄰的下層卷材搭接區,用機械緊固螺釘和固定墊片與基層固定,上層卷材與下層卷材的搭接采用熱空氣焊熔接,使卷材連接成一個(gè)整體密封的防水層。根據工程需要接縫外邊緣用密封膏封嚴。<br />
TPO(熱塑性聚烯烴)防水卷材機械固定系統的施工特點(diǎn)<br />
● 受天氣因素影響小,施工迅速、固定可靠。<br />
● 專(zhuān)用的固定件適用于不同的基層。<br />
● 可承受較大風(fēng)速引起的負壓抽吸,保證系統的安全性。<br />
● 采用織物內增強卷材,能有效避免釘眼部位的卷材出現拉裂的問(wèn)題。<br />
● 系統安裝成本低。</p>
