Demoulding method for metal template and cement product

Abstract

The invention provides natural demoulding technology for realizing effective isolation of a metal template and the surface of a concrete material product, which comprises that: a conductive surface forming appliance for steel and aluminum metal templates and the like is utilized, metal electrode bars with insulating protective hooks in concrete materials such as newly cast hydrous cement and the like are inserted into a plate in rows, output positive and negative poles of a special power supply device are connected with a system consisting of the electrode bars and the metal templates by leads respectively, the electrolytic action is produced in the concrete material clamped by the electrode bar and the metal template when the concrete material is poured into the plate and the plate is powered on, and a water vapor mixing layer is produced between the metal template and the concrete material. Compared with a large amount of conventional harmful solvent type demoulding agent which only meets disposable use, the invention provides a simple, convenient, effectively, low-carbon and environmentally-friendly demoulding method with the advantages of simplified process, low cost, high work efficiency, no pollution, long efficiency and long service life or long-term use for performing construction by using the forming appliance for the templates and the like and producing the concrete material products such as cement and the like.

Description

technical field [0001] The invention belongs to the technical field that the metal building formwork and other forming appliances on conductive surfaces such as steel and aluminum can replace the traditional release agent to complete the release process. Concrete, cement and other water-containing coagulation materials construction or the manufacture of newly poured cement and other coagulation materials components and other products, and through the use of metal and other conductive surfaces of different shapes, electrode rods and special power equipment combination systems, after the products are cured , can realize the method of effective release treatment between the conductor material and the surface of concrete and other concrete products. Background technique [0002] Existing metal formwork such as steel formwork is used in the construction and manufacture of cement products such as cast-in-place concrete, as well as in the production of all water-containing cementit...

AI Technical Summary

Problems solved by technology

[0003] In the traditional release agent used in the existing formwork release treatment, the solvent volatilization affects the health of the operator; the chemical composition in the oily release agent causes the inherent strength of the surface of the concrete material to decrease; in reinforced concrete construction , after the release agent is applied to pollute the steel bars accidentally, it will affect the construction quality of the structure; unforeseen factors such as human operation will cause dust and noise pollution caused by cleaning the concrete and other dirt on the surface of the formwork after the formwork is removed; The volatilization and flow of the chemical release agent on the surface of the formwork and the cleaning of the formwork will cause environmental pollution to the air and groundwater sources; when cleaning the formwork, water resources need to be consumed; the purchase of the release agent, fire prevention and quality assurance, etc. Manual and mechanical handling such as brushing release agent, cleaning templates, reversing or cranes, etc., repairing or reworking defects on the surface of finished products, repairing template loss and defects, fines, and dealing with finished products caused by oily release agents for subsequent processes Surface interface treatment, etc., all consume management, mechanical and human resources
