Construction process of Qingyang high-density polytetrafluoroethylene board

Sulfur trioxide dissolves in rain and dew to form sulfuric acid. Acid rain, acid mist, and acid gas will react with calcium carbonate to produce relatively loose calcium sulfate, commonly known as gypsum. Acid mist is the main cause of surface loss of calcium containing stone. Gypsum is a hydrated crystalline expansive substance that dissolves and washes away calcium sulfate expansive substances in areas frequently washed away by rainwater, forming dissolution. In areas where rainwater is difficult to wash away, loose calcium sulfate easily adsorbs dust and forms a black scale layer. When the scale layer thickens to a certain extent, it will form blister like or sheet-like protrusions, and even peel off. If the stone contains a high amount of magnesium carbonate, it will cause small pores to form on the surface of the carbonate rock. 6. Salt alkali spots, white spots, and powdery salt alkali spots are white solid marks formed by salts or alkalis in the micropores of stone and presented on the surface of the stone.
The PTFE stair board must be 5mm thick, with a length equal to the length of the stair board; The width is the step width. Cutting the PTFE board on the stairs requires the use of a profile cutting machine for cutting. The general market price is divided into two types: pure materials and recycled materials.

Polyethylene tetrafluoroethylene board has low lubricity and plays a buffering role in earthquake resistance.

1. We attach great importance to the safety of residents' homes.

2. The frequent occurrence of natural disasters leads to the damage of stairs, making it impossible to escape and rescue.

3. Polyethylene tetrafluoroethylene board has low lubricity and plays a buffering role in earthquake resistance.

Why does PTFE stair board always use 5mm function? In recent years, PTFE stair slides have been widely used and have been widely used in most buildings.

Different types of stone have varying rates of weathering based on their structure, hardness, composition, and usage environment. Studying the weathering problem of stone is beneficial for further placing different types of stone in more suitable building locations during design, in order to prolong the service life of buildings and decorations and achieve better decorative effects; It is also conducive to fully utilizing the increasingly mature stone protection and maintenance technologies in recent years to protect stones. Marble (mainly carbonate) in stone is generally considered to be more prone to weathering than granite, mainly due to the increase in acidic substances caused by human living and production environments, especially acid rain, which exacerbates the erosion of building decorative surfaces and causes severe damage to the stone used for exterior decoration; Compared to granite mainly composed of silicates, silicates have higher stability and are less prone to weathering compared to marble.
Polytetrafluoroethylene sheet is refined from 100% pure polytetrafluoroethylene through various processes such as molding, turning, cutting, etc. It has good chemical corrosion resistance, no aging, electrical insulation, and extremely low friction coefficient among known plastics. It can be used at temperatures of -180+260 degrees Celsius under no load.

Usage: Flat pads, V-shaped pads, lining materials, etc. Sealing materials: piston rings, guide rails, etc. Lubrication materials: electrical insulation materials: anti sticking materials, etc.

PTFE PTFE sheet specifications:

Thickness (mm) 0.2-6mm

Width (mm) 250, 300, 400, 500, 850, 1000, 1200, 1500, 1800, 2000

Length: (mm) 500.

Alkali cleaning: mainly for acidic pollutants. After using it at home for a period of time, there will inevitably be oil stains, tea, etc. How to perform maintenance? Cleaning method: Generally, neutral cleaning agents are used to clean and soften with flexible materials. Protection method: Use penetrant protective agent, which can penetrate into the stone and seal the micropores of the stone, preventing the entry of pollutants and protecting the marble from being contaminated. And better protection is achieved by using a penetrating protective agent followed by a surface type protective agent. Regular maintenance: Use neutral cleaning agents for cleaning, and if necessary, use polishing agents to polish the countertop, making the stone appear high brightness.

Detailed introduction to the construction process of polyethylene PTFE board for stairs:

1. Clean the surface of the stairs and do not allow sharp particles.

2. Lay plastic wrap.
3. Use polyethylene PTFE board for laying stairs.
4. Bolt fixation (note: spacing, edge distance).
5. Perform pouring.

SBS modified asphalt tile waterproofing membrane is particularly used for waterproofing buildings in cold and structurally deformed areas, while SPP modified asphalt waterproofing membrane is suitable for waterproofing buildings in high temperature and strong solar radiation areas. Construction operation requirements for SBS waterproofing membrane: Basic requirements: The base layer must be flat, clean, and dry, with a moisture content of less than 9%. Then, the surface of the base layer should be evenly coated with primer and brushed until it is dry before construction can begin. SBS waterproofing membrane laying sequence direction: high first, then low span; At the same height, go far first and then come close; Lay the same plane starting from the lower part. Lay in the direction parallel to the ridge when the slope of the paving direction is 3%; Lay parallel or perpendicular to the ridge direction when the slope is between 3% and 15%: Lay perpendicular to the ridge direction when the slope is 15%.
