The water absorption rate of XPS is beyond doubt, and it has excellent waterproof properties; However, the water absorption rate of sulfoaluminate porous insulation board is within a predetermined range, from 2-11 (v/v%), which has its particularity and controllability: generally used in external wall insulation, we control the water absorption rate of the board at 7-8 (v/v%) through technology. As the main body of the board is composed of cement, the water absorption rate is controlled within this range for easy bonding with cement mortar to make it stick firmly without virtual adhesion or hollowing off. However, this water absorption rate does not affect its insulation performance because the entire system has excellent waterproof properties. The sulfoaluminate porous insulation board external wall insulation system has been tested by the Sichuan Construction Engineering Quality Inspection Center after 8 high-temperature water spraying cycles and 5 heating and freezing cycles. The tested system specimen did not produce any water seepage cracks, and there were no defects such as hollowing, peeling, or bubbling.
The thickness of the PTFE board used for stairs is 5mm, with a length equal to the length of the stair board and a width equal to the width of the stair tread.

Various specifications with a width of 26cm/27cm/28cm/300cm can be customized for regular use. According to customer needs, the PTFE board for stairs can be cut using a profile cutting machine. After the completion of the staircase PTFE board device, cover the simple purified areas with adhesive paper iron or use plastic film to cover and protect them. Stop using the quiet guardrail to protect the easily scratched area.

Industry insiders analyze that the common preventive measures for granite hollowing include the following six points: 1) Medium coarse sand should be used as the sand, and it should be witnessed that the sampling and inspection are qualified before it can be used in engineering. Drinking water should be used as the mixing water for mortar and plain cement slurry. For those whose water properties cannot be determined, they should be sent to the laboratory for testing. Only after passing the test can they be used in engineering. Construction shall be carried out strictly in accordance with the requirements of the construction process standards. The base layer shall be cleaned and moistened with water. After self inspection and passing the inspection, the supervising engineer shall conduct concealed acceptance before applying plain cement slurry and laying 1:3 dry hard mortar. Each concealed layer shall be inspected layer by layer to ensure no loopholes. Avoid using acidic or alkaline cleaning agents. Due to the fact that the main component of granite is natural marble, which belongs to limestone and is mainly composed of calcium carbonate (CaCO3), non neutral substances can damage its luster. In order to achieve a good cleaning effect, cleaning agents on the market often use acidic and alkaline substances as raw materials, which can cause the loss of luster and affect the appearance of the granite. It is recommended to avoid using non neutral acidic or alkaline substances such as * and tile cleaners. Do not cover the carpet for a long time. Covering the surface of the granite with a carpet for a long time without replacement or ventilation, the moisture in the granite itself cannot be released through the capillary pores, resulting in an increase in the moisture content of the granite and causing the surface of the board to "spit out" water vapor in the future.

Direct component guide, select stairs. Luban steel stairs are usually arranged with scattered components. Component, the latter of the di items in the board. Polytetrafluoroethylene is a solid material with a known low coefficient of friction, and is corrosion-resistant and aging resistant. It is a material for staircase joints, and the performance of other alternative materials is much lower.

The application of low friction performance in load is due to the fact that some equipment's friction parts are not suitable for lubrication, such as in situations where lubricating grease will be dissolved by solvents and fail, or products in the fields of papermaking, pharmaceuticals, food, textiles, etc. need to avoid lubricating oil contamination. This makes PTFE filling material an ideal material for oil-free lubrication of mechanical equipment parts (directly bearing loads).

Most families choose solid wood dining tables, but the popularity, texture, and high-end quality of marble dining tables have become the pursuit of more and more families. Let's take a look at some related characteristics of marble dining tables together: Marble, because of its smooth surface, is generally not easy to wipe off water and oil seepage in a timely manner. After a long time, the only remedy is to brush the varnish again. 2： Marble dining tables are more upscale, but not as healthy as solid wood flooring materials. 3： Marble dining tables are more suitable for large apartments because marble is bulky to transport. Not very suitable for moving. The relative advantages of marble are: 1. It does not deform; High hardness and strong wear resistance.

This is because the friction coefficient of the material is known to be in solid materials. Its specific uses include bearings for chemical equipment, papermaking machinery, and agricultural machinery, as piston rings, machine tool guides, and guide rings; Widely used in civil and architectural engineering as support blocks for bridges, tunnels, steel structure roofs, large chemical pipelines, storage tanks, as well as bridge bearings and bridge rotors.

The closed cell rate and dimensional stability of polyurethane rigid foam insulation layer should be paid special attention to its shrinkage performance under high humidity and low temperature, high humidity and high temperature conditions. In addition to focusing on bonding strength, various adhesive pastes, crack resistant mortars, and jointing pastes should also pay attention to their comprehensive indicators of freeze-thaw resistance, impermeability, and crack resistance. Anchor bolt building accessories should not only focus on the tensile strength of single nails, but also pay special attention to the effectiveness and aging life of connections with solid walls, air blocks, and lightweight blocks. Application technology: When many chemical building materials are combined together, how to form a mutual connection and life matching, how to achieve overall optimization of performance and life, and form a complete coating finish, brick finish, and other decorative engineering structure can only be achieved through application technology research to form a technical system that can be used in practice.
