METHOD OF PRODUCING A VINYL CHLORIDE RESIN FORMED ARTICLE |
摘要 |
<p>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.</p> |
