Calcium silicate board production mode, the copy method and the quality of the comparison method, which prawn know
At present, with the improvement of process control level, the gap is not so big, the capacity of the upstream slurry method by increasing the width of the blanket, the quality of the press and template surface treatment to enhance, but the relative equipment investment will be large ( Japan and Taiwan can not copy the template, but because of the differences in the level of process control, the majority of domestic product copy quality products can not reach the level of the Japanese level). There are two ways to integrate business, such as Etienne, with a blanket, the production of different products can be two ways to switch at any time.
External wall of calcium silicate board seams posted why the grid is also cracked
First, whether the gap between the calcium silicate board (plate) is caulked with the caulking agent, because the outdoor long-term sun and rain, the reasons for thermal expansion and contraction
Is the calcium silicate board and the Etter plate the same material?
Calcium silicate board is the domestic follow-up imitation of the product. Although the raw materials are basically the same, but the proportion of raw materials and other ingredients added, as well as the production process is different due to the differences in these factors, product density, water resistance, fire performance are very different.
What is the difference between perforated calcium silicate wallboard and gypsum board?
Silicon calcium board was first used in high temperature furnace insulation. Such as "in order to improve the quality of shaft kiln clinker material, easy to coal blending and reduce clinker burning coal consumption, we must strengthen the kiln kiln body insulation.Often the practice is to use the internal insulation method, refractory layer, the total thickness of the insulation layer should be ≥ 650mm, near the kiln wall should be added ≥ 60mm calcium silicate board or aluminum silicate fiber mat ".
What is the difference between silicon calcium and cement fiberboard?
Fiber cement pressure plate and calcium silicate board in common 1, both of the raw material composition is similar, all contain silicon powder, calcium and fiber. 2, both through the process of pulping and copying. 3, both the appearance of the shape and length and width specifications are basically the same. 4, both in the use of many overlapping areas, such as inside and outside the wall and so on.
What is high strength microporous calcium silicate board
Microporous calcium silicate board is prepared by dynamic hydrothermal method and pressure molding. Dynamic hydrothermal method is used to make light slurry. The slurry is mixed with glass fiber to remove water. After molding, it can be dried. Part of the glass fiber and strong pressure, into a plate is completely physical process. This product does not do the top of the ceiling, why, its strength is by squeezing out, there is no chemical combination, in the wet state no strength, so can not be too thin, dry and cut into thin sheets easily broken and out Gray, I have seen are generally more than 3 cm thick block, used in a variety of fire insulation purposes, the intensity is relatively low, the national standard GB / T10699-1998 have introduced the density of 0.22 the following, the intensity is very low, no high strength Of the Japanese standard, there are 0.35-0.55 density range of the standard, the intensity of about 2MPa or so, as the density of 0.55 or more, can be done with ordinary calcium silicate board, the lower the cost, so generally do not see this Density of microporous calcium silicate products;
My house decoration with a lot of calcium silicate board, harmful to people?
Calcium silicate board consists of a variety of organic and inorganic substances, the use of advanced program-controlled equipment and flow slurry process production molding, high temperature autoclaved curing and special technology processing, is an environmentally friendly, safe, multi-functional high-level building With the plate. Product composition High-purity quartz sand + mica + perlite and other mineral fillers + plant fiber + moderate amount of low-alkali cement
What is the amount of tropicin in the calcium silicate board? Or how to define? What is the effect of the content on the quality of calcium silicate board?
So that calcium silicate board is actually Tremere to stone crystal with fiber reinforced. If the reaction is incomplete in the autoclave, the formation of the beta-tropicite crystals is not enough, resulting in a sharp decline in the strength of the calcium silicate board, and even cause waste (soft plate).
