Floor base construction plan, construction guide

Construction plan for different material foundations:

1) Cement mortar leveling layer: humidity below 6%, using R777 base oil or PE260 base oil treatment: 1:1 watering; 2) humidity above 6%, below 8%, using Huada epoxy base oil treatment 8% or more, postponement of construction; 3) smooth surfaces such as terrazzo floors and tiles, treated with R777 or PE260, but not watered; 4) wood or steel foundations, since they do not need to be self-leveling, so as long as the surface treatment clean.

There are two approaches to solid wood flooring:

A method of brushing cold base oil on cement floors, laying wooden keels, and finally nailing floors; another method is to lay a layer of blockboard on the keel first, or a wool floor, and then nail the floor. In this way, the floor is Uniform force, firm structure.

Composite floors are easy to install and there are two ways to do this:

One is to make a leveling layer first, then a PVC cushion is laid, and then a composite floor is laid; the other is on a cement leveling layer, a wooden keel and a wool floor are laid, and a two-story composite floor is laid.

Flexible ground floor construction guide

First, the construction conditions of the ground floor must meet the national building surface engineering construction quality acceptance specification "GB50209-2002" prescribed for the cement base surface, "should be flat, hard, dry, dense, clean and free of grease and other impurities, shall not have hemp "Surface, sanding, cracks, and other defects" conditions before the material can be laid.

Second, the construction conditions:

Within 48 hours before and after the laying of PVC flooring, the construction site must be kept clean, closed, weatherproof and maintain a constant temperature. In addition, the degree of dryness on the ground is also crucial for the construction of PVC flooring. So before laying the floor:

1. Use a moisture content tester to measure the moisture content of the base layer, and the moisture content of the base layer should be less than 3%;

2. The most reliable way to measure the moisture content of the ground is to measure the relative humidity of the concrete, and the test point must be in the most humid place. It cannot be measured at the window or doorway because the test value may be too low. The depth of the test must also be taken into account: the suspended concrete surface is 20% deeper from the surface, and 40% deeper from the mud surface;

3. The use of thermometers to detect temperature, indoor temperature and surface temperature of 18 degrees is appropriate, should not be below 5 degrees and 30 degrees above construction;

4. The relative air humidity suitable for construction shall not exceed 60%. If the moisture-proof layer has been added, the relative humidity may be up to 85%, but once it exceeds 85%, it cannot be laid;

5. PVC floors cannot be directly laid on cement floors with rising moisture. They must be ventilated first, or a layer of moisture-proof layer must be laid first.

Third, the basic floor requirements and processing:

Prior to the laying of PVC flooring, the ground conditions were the most important. The quality of the ground directly affects and determines the effectiveness and appearance of the flooring. The ground must be solid, smooth, dry, and clean. Use a floor polisher with more than 1000 watts and an appropriate grinding pad to grind the floor as a whole. Remove paint, oil stains, chemical solvents, sulfides or cured products, sealants, asphalt and glue, etc., raised and loose. Plots and empty drums must also be removed. Floor vacuum cleaners shall be cleaned with an industrial vacuum cleaner of not less than 2000 watts. For cracks on the floor, white cement and gypsum can be used for repair;

Chromium Oxide Abrasive

The high chromium wear-resistant alloy steel balls produced by our company have the following advantages:

1. With extremely high hardness, usually between 60-66 HRC, it can effectively resist wear and grinding and extend service life.

2. Excellent wear resistance, able to maintain stable performance during high-speed grinding and grinding, reducing the risk of wear and fracture.

3. It has good impact resistance and can withstand greater impact force and is not easy to break during high-speed grinding and grinding.

4. It has good corrosion resistance, can maintain stable performance in wet and corrosive environment, and is not easy to rust and corrosion.

5. Can maintain stable performance in high temperature environment, not easy to deform and soften, suitable for high temperature grinding and grinding process.

6. The wear rate of the steel ball is low, which can reduce the loss of abrasives and materials and improve the grinding and grinding efficiency.
