Special stone formula for pipeline
The invention provides a special stone formula for pipelines, and relates to the technical field of pipelines. The special stone formula for the pipeline comprises the following raw materials in parts by weight: 50-55 parts of a base material, 30-35 parts of an auxiliary base material, 10-15 parts of a reinforcing base material and 10-20 parts of an adhesive, the base material is calcite, the auxiliary base material is ardealite, the reinforcing base material is iron-ore slag, the adhesive is resin, the particle diameter of the ardealite is 5-50 microns, and the content of crystal water is 20-25%. The ardealite of the auxiliary base material mainly comprises grey black and grey white, the ardealite is a solid waste generated in a wet-process phosphoric acid process, the component of the ardealite is calcium sulfate dihydrate, and the ardealite is introduced as the auxiliary base material, so that waste utilization can be realized, the raw material cost of the pipeline is reduced, the dust pollution of the ardealite is reduced, and the production cost is reduced. Meanwhile, the iron-ore slag is added into the material, so that the strength of the pipeline can be greatly improved, the water tightness of the water pipe is effectively prevented from being reduced by the phosphogypsum and the iron-ore slag, the water pipe is prevented from being aged too fast, and the service life of the product is prolonged.
本发明提供一种管道特种石材配方，涉及管道技术领域。该管道特种石材配方，包括下述重量份的原料：基材50‑55份、辅助基材30‑35份、加强基材10‑15份、粘合剂10‑20份，基材为方解石，辅助基材为磷石膏，加强基材为铁矿渣，粘合剂为树脂，磷石膏颗粒直径为5～50μm，结晶水含量20～25％。本发明中辅助基材的磷石膏主要有灰黑色和灰白色两种，磷石膏是湿法磷酸工艺中产生的固体废弃物，其组分主要是二水硫酸钙，通过引用磷石膏作为辅助基材既可以实现废物利用，降低管道的原料成本，同时降低磷石膏粉尘污染，同时本发明材料中加入铁矿渣可以使得管道的强度大大增加，且磷石膏和铁矿渣有效的避免水管的水密性降低，使得水管避免过快老化，延长产品的使用寿命。
