Abstract
The invention discloses an alloy material for a water pipe. The material is characterized by comprising, by weight, silica with the SiO2 content greater than or equal to 97%, 8-15% of lime with the CaO content greater than or equal to 90%, 10-15% of barite with the BaSO4 or BaCO3 content greater than or equal to 80%, 30-35% of coke with the C content greater than or equal to 80%, 3-6% of fluoritewith the CaF2 content greater than or equal to 80% and the balanced steel chips, 0.5-1% of AL, S less than or equal to 0.05%, P less than or equal to 0.05%, 2%-4% of silicon dioxide, 15%-20% of talcumpowder, 10%-20% of mica powder, 3%-5% of micro silica powder and the balanced Fe. The alloy material has the advantages of being safe, hygienic, healthy and durable, the problem of plastic pipeline contamination is eliminated, the price is reduced a lot compared with a copper powder, and the alloy material is a priority water pipe material.
Description
technical field [0001] The invention relates to the field of composite material manufacturing, in particular to an alloy material for water pipes and a preparation method thereof. Background technique [0002] Water pipes are water supply pipes. Modern decoration water pipes are built with buried walls. There are three types of water pipes. The first type is metal pipes, such as hot-dip cast iron pipes with plastic lining, copper pipes, and stainless steel pipes. The second category is plastic composite metal pipes, such as plastic composite steel pipes, aluminum-plastic composite pipes, etc. The third category is plastic pipes. As water pipes, after several years of use, a large amount of rust and scale will be generated in the pipes. The yellow water flowing out will not only pollute the sanitary ware, but also be mixed with bacteria that grow on the rough inner wall. Therefore, there is an urgent need in the world for a water pipe with low installation risk, suitable for...
