    摘要: A method of producing a nonfoamed formed article of a vinyl chloride resin by mixing a hydrated water-containing gypsum powder and a vinyl chloride resin powder together, and heating the obtained mixture at a temperature lower than a temperature at which the vinyl chloride resin starts decomposing thereby to remove the hydrated water of the gypsum and to form the mixture. The method makes it possible to obtain a nonfoamed formed article free of defective appearance by directly adding the hydrated gypsum (specifically dihydrate gypsum) to the vinyl chloride resin without converting it to the anhydrous gypsum, without requiring wasteful energy cost, without causing foaming or defective forming stemming from the hydrated water and maintaining stability.

    摘要: A process for neutralising exhausted sulphuric acid by means of production of di-hydrated calcium sulphate that provides the feeding of sulphuric acid (1) and of a soluble calcium salt (2) in a precipitator (3) for the precipitation of di-hydrated calcium sulphate, which is filtrated in a decantation plant (4), washed (5) and then dried (6,7,8). In the precipitator (4) a liquid acid phase and metal salts in solution remain. The calcium salt (2) can be obtained in a reactor (10) by a ion exchange reaction between a calcium ore (11) based on calcium carbonate and an exchanging acid that is stored (9) downstream the precipitator (3, 4) as liquid phase separated from the calcium sulphate (6) obtaining carbon dioxide (12). In a reactor (13) calcium hydroxide is added (14), whereby the metal hydroxides precipitate and decant in the plant (15). The calcium salt in solution is then stored in the starting reservoir (2). The di-hydrated calcium sulphate has acicular crystals of high quality, whereas the metal hydroxides can be calcinated and with the metal oxides resulting therefrom brick material can be obtained for the building industry.
