Embodiment

[0028] Example: Preparation of adhesive and iron-based copper micro-electrolysis profiles

[0029] (1) Glue-like adhesive formula (mass ratio)

[0030] Light magnesium oxide (industrial grade) 15 kg

[0031] Magnesium chloride hexahydrate (industrial grade) 3.5 kg

[0032] Silica sol (industrial grade) 1 kg

[0033] Sodium hexametaphosphate 1.5 kg

[0034] Water (pH=5-7) 29 kg

[0035] (2) Preparation process of profiles

[0036] 1) Preparation of glue: Weigh light magnesia, magnesium chloride hexahydrate, silica sol and sodium hexametaphosphate according to the formula ratio, add in the quantitative water according to the formula ratio in turn, stir quickly until completely dissolved, and obtain a transparent glue .

[0037] 2) Preparation of the mold: the mold is rectangular, and its size is limited to facilitate operation and transportation. There are no special requirements for the materials of the panels around the mold, iron, plastic and wood can be used, and the ...

Abstract

The invention relates to an adhesive and a method for preparing an iron-based copper microelectrolytic sectional material. Based on requirements for sewage microelectrolytic treatment methods, silica sol and sodium hexametaphosphate are added to reach the purpose of modification of magnesium oxychloride cement. Through the cementation effect of products obtained by reactions among components, the iron-based copper particles are cemented, and a cementation skeleton of the iron-based copper particles is formed which has certain strength, can resist acidic water corrosion, and has certain conductivity; therefore, collapse of a bed layer is inhibited; the service life and time is prolonged; and the hardening problem is solved finally.

Description

technical field [0001] The invention belongs to the technical field of wastewater treatment, and in particular relates to an adhesive and a method for preparing iron-based copper micro-electrolysis profiles. Background technique [0002] In the electrochemical reaction bed (layer) of iron-based copper micro-base material, the cast iron particles that act as a supporting framework, during the process of treating sewage through micro-electrolysis, due to the continuous reaction and dissolution of iron particles, their support strength continues to decrease until they collapse. Formation of bed compaction. Hardening will block and seal a large number of pore throats that originally pass through the sewage with the help of dialysis and undergo micro-electrolysis, and finally force the water to pass through only a small number of larger fixed channels, which makes the sewage treatment capacity of the iron-based copper fixed reaction bed obvious. decline. At present, one of the ...
