PPGI Corrugated Roofing Sheet Installation and Misunderstanding
PPGI Steel Sheet Installation
1. Dig the trough first, then the foundation, the brick foundation, and of course the foundation, depending on the situation. After that, the movable steel frame is installed. If it is multi-layer, install the prefabricated floor and then install the high quality PPGI corrugated roofing sheet. After the first floor is completed, the doors and windows are installed and the interior is finally finished.
2. The PPGI steel plate activity room is similar to the building, first level the perimeter and the partition wall. It is best to use reinforced concrete, which is relatively strong. Then set up the column, connect the skeleton with the transverse beam, the upper partition, the outer wall panel and the door and window frame; follow the floor and then put up a layer. Then go to the roof truss and roof slab; finally install the doors and windows, etc., pull the vertical support, then the sanitary ware, hardware and the like.
3. The concealed project of the PPGI steel plate movable room refers to the part that will be covered by the next process after the completion of the previous process in the construction process, and all the inspections cannot be carried out after completion. To do room decoration, “concealed project” is the key. If the “concealed project” is not done well, the surface decoration is beautiful and futile. The concealed project is divided into water installation, electric installation, moisture-proof and waterproof projects, and each of these projects cannot be ignored. If there is a problem with any link, it may bring serious economic losses. It even hurts personal safety. The construction process and material identification of the waterproof project must be done well to avoid unnecessary economic losses and injuries. After the completion of the PPGI corrugated roofing sheet activity room, the roof and wall surface shall be flattened, and the ridge, gable and the lower end of the wall shall be in a straight line; the flooding parts shall be in a straight line; whether the connecting parts are vertically and horizontally aligned; the long-term splicing of the PPGI plate structure into one Straight line, the plates are sewn into a straight line, and perpendicular or parallel to the relevant axes; the PPGI plates should be uniform in PPGI, no pollution, and the damage should be repaired in time; ensure the fastening of the joints without looseness, and the surface of the plates is not pressed by the fasteners. Concave phenomenon; the PPGI plate surface has no wrinkles, and no holes are punched.
Out of the Misunderstanding of Fireproof PPGI Steel Plate
In today’s fireproof building materials, rock wool PPGI steel plate is a very popular type of application, so many people buy PPGI corrugated roofing sheet. This PPGI steel plate occupies a large share in today’s wall system and roofing system, and the cost of this high quality PPGI corrugated roofing sheet is low. The good characteristics also make the market of rock wool PPGI steel plate expand continuously, and in order to let people better understand the superiority of this building material, China PPGI corrugated roofing sheet factory also sorted out some parameters of rock wool PPGI steel plate.
Building fires are terrible things that no one wants to see. Rockwool itself is a silicate fiber inorganic material, non-combustible, rock wool has thermal insulation, and belongs to Class A fireproof material. When using rock wool PPGI steel plate, not only the effect of heat preservation is ensured, but also the fireproof performance meets the fireproof standard. To do a good job in the fire protection of external wall insulation, we need to do the following: One is to strictly enforce various fire regulations and strictly implement the fire protection system. Select the insulation material, do the fire prevention measures for the primary stage of the use of the insulation material, monitor the construction process at the intermediate stage of the use of the insulation material, and prevent the possibility of various fires; after the insulation material is made into the external wall insulation system, do Good use of the insulation system and prevention of fires.
Rock wool PPGI steel plate is a PPGI corrugated roofing sheet with intermediate core material as rock wool. The thickness of the upper and lower steel plates can reach 0.25-0.8mm, and the density of rock wool can reach 120-150kg per square. The rock wool PPGI steel plate has a very good flame retardant effect and sound insulation effect, and its flame retardant grade can reach A grade, so it is also very safe. The application of rock wool PPGI steel plate is very strong, and the roof, wall, ceiling and partition can be very convenient to apply. In addition, the rock wool PPGI steel plate is also very environmentally friendly, so this type of building has played an extremely good promotion effect in today’s applications.
Detailed Development Trend of PPGI Steel Sheet
First, the use of high-quality substrates, the surface, plate shape and dimensional accuracy requirements of the substrate are getting higher and higher, outdoor use such as small zinc flower flat hot-dip galvanized steel coil, zinc-free flower flat hot galvanized steel coil in time The rise of zinc alloy hot-dip coils; indoor use such as electro-galvanized steel coils, foil cold-rolled sheets and aluminum coils.
Second, the improvement of the pretreatment process and the pretreatment liquid, the number of equipment is small, the cost is low, and the mainstream process is continuously improved, and the stability, corrosion resistance and environmental performance of the pretreatment liquid are continuously improved.
Third, pay attention to the development of new coatings, improve the general polyester, polyvinylidene fluoride (PVDF) and plastisol, obtain super PPGI reproducibility, anti-ultraviolet, anti-sulfur dioxide, improve corrosion resistance; develop pollution resistance, suction Functional coatings such as heat.
Fourth, the unit equipment is more complete. Such as the use of new welding machines, new roller coating machines, complete curing ovens, and advanced automation instruments.
Fifth, because cold embossing has lower cost than hot embossing, it has the characteristics of beauty, three-dimensionality and high strength, which makes the cold embossing production technology become the development trend.
Sixth, pay attention to product diversification, functionalization, high-grade, such as deep-drawing PPGI coating board, “Pomelo peel” PPGI coating board, anti-static PPGI coating board, pollution-resistant PPGI coating board, high heat absorption PPGI coating board Wait.
What are Core Materials for PPGI Steel Sheets?
The sandwich material of the PPGI corrugated roofing sheet is divided into a foam PPGI steel plate (chemical name is polystyrene PPGI steel plate), a rock wool PPGI steel plate, a polyurethane PPGI steel plate, a paper honeycomb sandwich panel, and a glass wool PPGI steel plate.
Foam PPGI steel plate is an organic material, which has the characteristics of light insulation, light weight and easy installation. It has been widely used in recent years. One of the downsides is that the foamed PPGI steel plate is extremely easy to burn and does not meet the national fire protection requirements.
Rock wool PPGI steel plate is a new type of fireproof board with the strongest fire resistance performance in the high quality PPGI corrugated roofing sheet series. It is made of natural rock, blast furnace iron ore slag, etc., which are melted into filaments at high temperature and then solidified. The rock wool PPGI steel plate meets the secondary fire protection requirements of the clean workshop, and is the most ideal structural decorative plate for indoor ceiling and movable house construction. It has a fire resistance of 600 ° C and a fire rating of Class A. It is polystyrene and there is no comparison of polyurethane. Its core material is rock wool that cannot be burned.
The polyurethane sandwich panel is composed of upper and lower PPGI steel plates and intermediate foamed polyurethane. It is one of the most widely used building materials in the construction industry. It has good insulation, heat insulation and sound insulation effects. The polyurethane added with fireproof material does not support combustion.
Glass wool and phenolic foam cored steel plates are slightly more expensive than foam. The phenolic foam material is a polymer organic hard aluminum foil foam product which is formed by foaming a thermosetting phenolic resin. It has the characteristics of light weight, fire prevention, no fire, no smoke, no toxicity, no dripping, wide temperature range (-196～+200°C), no shrinkage and no embrittlement under low temperature environment.
