Description

Multi-channel ceramic floor turning technology capable of recycling

The invention relates to the field of building materials and preparation technology thereof, in particular to a multi-channel ceramic floor which can be recycled.

Background technique

Ceramic floor tiles are high-energy, high-emission, high-energy-consuming industries, including other existing building materials such as wood flooring and stone. The resources are limited, and their mining is extremely damaging to the environment, thus improving the use of ceramic tiles.

Book

Life or recycling is the only way to ecological protection. The existing ceramic floor tiles have a single function and a thin thickness. They are only suitable for wet laying. They are moisture-proof, sound-proof and have poor anti-slip function. Most of them use glaze, printing and inkjet processes. The colors are easy to age and not wear-resistant, and the service life is also short. The ground after construction is affected by the natural force of thermal expansion and contraction, and it is easy to damage the buried pipeline under the ground. If the common hot and cold water pipes leak, it is easy to damage the floor decoration materials, such as ground cracking and drumming. Moreover, the distance between the ground after construction and the floor heating pipe below it is more than 50mm. This construction method will result in slow heat transfer, low thermal efficiency, and increased energy consumption and carbon emissions. The severe air pollution in the northern part of the country is closely related to the low heat efficiency of heating. Especially in the densely populated central and southern parts of China, the winter is extremely wet and cold. Due to historical reasons, central heating is not planned in the central and southern regions. Every winter, every household adopts various methods. Heating, unsafe and energy efficient. A better method is to install a heating cable under the floor, which is safe, comfortable, and low in energy consumption. However, the heating cable must be installed in an active manner, but the ground construction cannot meet its requirements. The ground after construction is carried out by common operation methods. Various pipelines are buried deep in the cement. Any pipeline that is aging or leaking or needs to add a new pipeline must destroy the existing ground and other maintenance-free pipelines. It will bring huge economic losses and waste of resources. Summary of the invention

The object of the present invention is to overcome the above deficiencies and to provide a recyclable, multi-channel, thermal energy Description

Use high efficiency ceramic floor tiles.

4) Place the mud of step (3) in the old warehouse, and the moisture content of the mud is uniform after 24 hours of boring;

5) The mud of the step ( ) is vacuum extruded into a multi-channel brick, wherein the vacuum is 0.09 MPa, and the extrusion pressure is greater than 20 Bar;

6) The kiln is assembled, and the multi-channel bricks after molding are dried for 8-10 hours, wherein the drying temperature is not more than 150 'C, and the multi-channel bricks after drying are less than 1.5% and transported into the kiln for sintering;

7) Bake, ensure that the firing temperature is greater than 1100, and burn the finished product after 4 hours.

The invention has the advantages that: the ridge rock containing the weakly viscous minerals, such as pyrophyllite, ore, sericite, etc., is used to reduce the water content, ensure the aluminum content, and improve the toughness and strength of the finished product. Sticky The soil plays a role in improving the plasticity and yield of the green body. The flux and flux minerals such as potassium and sodium feldspar can reduce the sintering temperature and the water absorption rate of the finished product, and the calorific value in the waste residue can reach the waste. The effect of energy saving, in the process of brick making, combined with die extrusion into multi-channel cavity floor tiles, the thickness exceeds 35 hidden, the bending strength exceeds 60Mpa, meets the standard of EU dry-laid paving, can be dry or floor glue Simple processing of wet paving, multi-channel can realize various pipelines on the ground and various pipelines that need to be added in the future. The construction efficiency is high, and it is simple to change without destroying the existing structure. It can be recycled completely. It is a kind of low-cost consumables. Energy-saving and environmentally friendly products.
