Abstract

The invention discloses a non-phosphorus slow-dissolving glass water treatment agent. The water treatment agent is prepared through using a glass matrix and an additive, the glass matrix comprises 9-18wt% of sodium oxide, 23-28wt% of silicon oxide, 46-55wt% of boron oxide, 0.6-1.2wt% of potassium oxide and 1.0-2.0wt% of alumina, and the additive comprises, by total amount of the glass matrix, 10-12.5% of zinc sulfate (ZnSO4), 6.5-9.5% of sodium tungstate (Na2WO4) and 0.16-0.18% of silver nitrate (AgNO3). A preparation method of the water treatment agent comprises the following steps: fully stirring the glass matrix and the additive, uniformly mixing, melting at 1400-1500DEG C for 2-3h, carrying out cold curing fragmentation, drying, and screening to obtain the non-phosphorus slow-dissolving glass water treatment agent. The water treatment agent has excellent ingrained dirt removing, corrosion and scale inhibition, organism killing and cleaning effects.

Description

technical field [0001] The invention relates to a water treatment agent, in particular to a phosphorus-free water treatment agent. Background technique [0002] In the cooling tower of the central air-conditioning refrigerator of the building and the cooling water system of the factory, in order to solve the problems of metal corrosion of water pipes, scale deposition on pipe walls, and adhesion of bacteria and sludge, a variety of phosphorus-containing organic chemicals are used to inhibit corrosion, scale, and sterilization. For the treatment of algae, due to the cumbersome and complicated operation of water quality control, the dosing lags behind the water quality, and the concentration of chemicals in the water fluctuates greatly. Not only does the cost remain high (medicine costs, labor costs for cleaning the water system, and labor costs for a large number of water sample detection reagents during the operation period) , water quality regulation, water consumption, ele...
