Brief introduction of technical performance of Huili cement fiber board raised floor

The cement fiber board is made of high-density and new environmental friendly cement and fiber as the base material. The bottom surface is sealed with galvanized sheet, and its thickness is not less than 0.3 mm. There is no rubber strip around it for edge sealing. It has the properties of fire prevention and waterproof, and has high strength, which can meet the load-bearing requirements of the equipment.

Brief introduction of technical performance of Huili cement fiber board raised floor

Comparison and analysis of cost difference between "Huili" brand raised flooring and similar products in China

I. Technology R&D cost investment Huili company has its own independent R & D team, in calcium sulfate flooring research and development, cooperation with Nanjing University and the Chinese Academy of Forestry Wood Industry Research Institute, invested a large amount of scientific research costs, developed calcium sulfate products with high strength and good quality stability, and develop calcium sulfate flooring industry quality standards; in the all-steel flooring products, Huili company and the United States ASM Group to establish cooperation, the introduction of foreign production technology and mold. Ⅱ, the production cost of calcium sulfate products Serial number Project content Huili Products Domestic Similar Products 1 Main Materials Calcium sulfate raw material Selected natural α-extra high strength gypsum powder (CaSO4 1/2H2O) Advantages: green, high purity, good strength and toughness Disadvantages: relatively high cost Ordinary gypsum powder mixed with ordinary cement or fly ash Advantages relatively low cost DisadvantagesLow purity, low strength and toughness, not environmentally friendly Paper pulp Unbleached sulfate coniferous wood pulp ProsNatural wood pulp, green, no impurities, no odor, high floor strength Disadvantages relatively high cost Recycled pulp from waste newspaper and kraft paper Advantages low cost DisadvantagesMany impurities, odor, not environmentally friendly, low floor strength Glue Shanghai Nogawata Stick Glue AdvantagesEnvironmental protection, no pollution, firm paste Disadvantages Cost increase 、 Common resin adhesive Advantages relatively low cost Disadvantage: not environmentally friendly, poor adhesiveness Steel plate Shougang galvanized steel AdvantagesHigh hardness, good flatness, bending resistance and other properties, good rust resistance Disadvantages Increased cost Ordinary small steel mill steel plates Advantages relatively low cost. DisadvantagesMany impurities, poor steel properties, general bending resistance, general rust resistance 2 Production Process Calcium sulfate base material Single-piece preparation, single-piece production. In other words, after mixing all kinds of raw materials separately and evenly, through the automatic electronic weighing system, the amount of all kinds of raw materials required for each piece of board is accurately weighed according to the formula, and then it enters the mixing bin for production. The advantages ensure that each piece of product has uniform texture, stable quality and small density error Disadvantages: more procedures, time-consuming operation, higher cost Direct mixing and stirring of various raw materials in batches AdvantagesSimple process, easy to operate Disadvantage: Uneven texture of each piece, high or low content of ingredients, large error in density of each piece. 3 Key production equipment Ovens Huili company introduced two sets of German BISON automatic mesh belt drying equipment, the whole drying channel is about 30 meters long, divided into 5 levels, each level of drying channel adopts electronic digital technology to automatically control the temperature, to ensure that the whole drying process is in a constant temperature state. AdvantagesThe whole drying process is in a constant temperature state, the temperature difference between each place in the drying tunnel at all levels is less than 1℃, thus ensuring that each piece of calcium sulfate board substrate can be evenly dried, to achieve the moisture content, product qualification rate. DisadvantagesHigh cost of equipment, use and maintenance costs are large. Homemade traditional old ovens or kilns Advantages low equipment price and maintenance costs Disadvantages difficult to control the temperature in the oven channel to achieve constant temperature, the temperature difference between the various parts of the oven channel, generally 10 ℃ or more, calcium sulfate board can not be dried. In addition, if the temperature in the oven is too high, the substrate will be over-dried and the moisture content is too low, the substrate will be dusted, the strength of the substrate will be reduced, and it will be easy to break after the force; if the temperature in the oven is too low, the substrate cannot be evenly dried and the moisture content is high, the galvanized steel plate and the substrate cannot be firmly pasted, and there are often quality problems such as shelling, blistering and rusting of the surface steel plate. Note: The good or bad of the substrate directly affects the floor load-bearing and use safety, so the key to the quality of calcium sulfate flooring is the quality of

Analysis of the principle of Huili anti-static flooring

Static electricity is an objective natural phenomenon, generated in many ways, such as contact, friction, impulse flow, etc.. The basic process can be summarized as follows: contact → charge → transfer → coupling layer formation → charge separation. Human body due to its own actions and other objects in contact with the separation, friction or induction and other factors, can bring thousands of volts or even tens of thousands of volts of static electricity. Static electricity is the result of the loss of balance between positive and negative charges in the local range. It is a kind of electrical energy, retained in the object performance, with high potential, low power, small current and the characteristics of the short duration of action.

Analysis of the principle of Huili anti-static flooring

Technical performance comparison between electroplating and hot-dip galvanizing on the surface of Huili anti-static flooring accessories

Hot-dip galvanizing is much more corrosion resistant than electro-galvanizing, mainly because the thickness of hot-dip galvanizing is much thicker than electro-galvanizing, but the appearance of hot-dip galvanizing is worse than electro-galvanizing. The cost of hot-dip galvanizing is higher.
