各种防水衬垫系统膨润土防水毯身经百战
在封(feng)闭式的情况下(xia)见水(shui)(shui)时(shi),膨润(run)(run)土(tu)会(hui)澎涨产生一个低亲水(shui)(shui)性(xing)的黏土(tu)壤层(ceng),其(qi)防(fang)(fang)水(shui)(shui)性(xing)等于(yu)几英寸厚的缩小(xiao)粘土(tu)。其(qi)与众(zhong)不同的特(te)性(xing),包含(han)提(ti)升(sheng)內部抗剪切应(ying)力(li)和长期性(xing)的抗应(ying)力(li)松弛摩擦阻力(li),使(shi)复合(he)型膨润(run)(run)土(tu)防(fang)(fang)水(shui)(shui)毯合(he)适运用于(yu)各种各样防(fang)(fang)水(shui)(shui)垫片(pian)系(xi)(xi)统(tong)软件(jian)。它能在拉申(shen)、部分(fen)凹陷、湿区循(xun)环系(xi)(xi)统(tong)和冻融循(xun)环等状况下(xia)维持(chi)非常低的吸水(shui)(shui)性(xing)。另(ling)外还具备工(gong)(gong)程(cheng)施工(gong)(gong)简洁(jie)明了、低成本、节约施工(gong)(gong)期等优势。
