2Million m2 Dry Wall Machine

At present, there are almost twenty giant paper gypsum board manufacturing strains beneath building and proposed in the country, of which six are manufacturing strains with an annual output of extra than 20 million m2. From the point of view of the producers that have been put into manufacturing and the producers that are to be built, most of them are placed in the japanese coastal zone, which is immediately associated to the wealthy gypsum assets in East China, the developed economic system in the east, and the pretty developed gypsum board market. From the contemporary operation of home designed manufacturing lines, there are mostly the following issues to be solved.

Compared with overseas superior countries, home gypsum board manufacturing line paper gypsum board best indications have the following gaps:
Weight per unit area: gypsum board of the equal thickness is 2Kg/m2 heavier than that of overseas countries.
Appearance: The home board has a giant hole with the gypsum board produced by means of overseas tools in phrases of the flatness of the board and the structure of the edge, and there is extra leakage at the sticky side of the top and decrease paper, and the facet form of the gypsum board is irregular. Therefore, gypsum board is inclined to cracks for the duration of joint construction. Of course, at present, the high-quality of seam gypsum powder iis no longer too clearance is additionally one of the primary reasons.
Moisture content: The moisture content material of home plate fluctuates greatly, even though the countrywide general stipulates much less than 3%, however the proper manufacturing is frequently the part water standard, the central water content material exceeds the standard, or the moisture content material in a batch of plates is exceedingly different.
Low plate deflection value: Because the home plate dodging does now not use paper fiber, the most deflection of the produced plate is no longer as true as that of overseas merchandise when doing floor construction, and it is effortless to be brittle and handy to fold.
