Asbestos cement and production process thereof
The invention discloses asbestos cement which is prepared from the following raw materials in parts by weight: 30 to 40 parts of asbestos wool, 100 to 110 parts of Portland cement, 1200 to 1300 parts of clear water, 0.3 to 0.8 part of a defoaming agent and 15 to 25 parts of river sand aggregate; according to the asbestos cement, firstly, the defoaming agent and other auxiliary materials are added, the defoaming agent and asbestos wool are mixed in a container so that the asbestos wool can be sufficiently loosened and completely soaked, the defoaming agent plays a role in foam inhibition and foam breaking so as to facilitate smooth subsequent stirring and mixing procedures, 1200 parts of clear water with the water temperature of 20-30 DEG C are divided into three parts according to the proportion of 590 parts: 590 parts: 20 parts, the asbestos wool is soaked and bubbles are removed through two pieces of 590 parts of clear water, then harmful dust and impurities are filtered, 1200 parts of clear water are divided into three parts, the three parts of clear water are stored by three different stirring containers, the containers can be replaced to screen residues and harmful substances left in the previous stirring and mixing process, and the continuous residue in the formed asbestos cement is avoided.
本发明公开了一种石棉水泥，该石棉水泥由以下重量份数的原料组成：石棉绒30‑40份、硅酸盐水泥100‑110份、清水1200‑1300份、消泡剂0.3‑0.8份、河砂骨料15‑25份；本发明首先，添加去泡剂以及其他辅料，通过去泡剂与石棉绒混合与容器内部，使石棉绒能等到充分的松懈，完全的浸湿，通过去泡剂起到抑泡、破泡，进而便于后续搅拌混合工序的顺利，通过将1200份水温为20‑30℃的清水分成三份，比例分别为590份：590份：20份，通过两个590份清水先使石棉绒完成浸湿，去除气泡，再将有害粉尘与杂质进行过滤，采用将1200份清水分成三份，且三份清水由三个不同的搅拌容器进行储存，可以更换容器对前面搅拌混合工序残留的残渣与有害物质进行筛分，避免其继续残留在成型的石棉水泥中。
