Abstract
Description
Hg+S→HgS
石油精製所からの粒径が60μm未満の元素硫黄および硫黄ポリマ(STX(登録商標))を使用した。粒径が4mmと6.30mmの間である砂利および4mm未満の粒径まで破砕されたケイ砂の乾燥混合物を骨材として使用した。0.125mm未満の粒径を有する炭酸カルシウム(99.5%純度)を微粒子材料として使用した。それぞれの比は、重量%として表され、これらは30−60−10(砂利、砂および微粒子)であった。粒度分析曲線を図1で示す。これらの実施例で使用される水銀は、塩化ナトリウムの電気分解により塩素を得るための工場から来ている。
100gの混合物あたり86.2gの水銀および13.8gの硫黄により構成される液体Hgおよび元素Sの混合物を調製した。これらの比を、HgS(式1)の形成のための化学量論的反応に合わせた。形成反応は遊星ミルプルベリセッテ6により提供される機械的エネルギーを介して、5.4のボール/ロード重量比、400rpmの速度、および1時間のミリングで実施される。
前の工程で得られた硫化水銀(HgS)を使用し、それらを骨材、元素硫黄および硫黄ポリマから構成される混合物中に組み込むことにより、石材の生成を実施した。
表1で記載されるポリマセメントの圧縮および曲げ引張に対する機械抵抗の研究(表2)をその後実施し、ユニバーサルイベールテストオートテスト(Universal Ibertest Autotest)200−10−W機械で決定した。ローディング速度は、UNE196−1標準に従い、曲げ引張において0.05kN/s、圧縮において2.4kN/sとした。表2は、得られたデータを含む。HgSを含まないサンプルは、他のものと同じ条件下であるが、硫化水銀の添加なしで得られた参照サンプルである。
