| 摘要 |
Invention is related to composite material based on polyvinylchloride (PVC), where as filler is used certain fractions of mineral industrial waste oil shale ash more specifically dust burn ash and boiling layer burn ash. Such a composite material has reduced or does not at all have HCl emission in increased temperatures. Oil shale ash added to the PVC contains a certain amount of free CaO, wherein due to its chemical reactivity it is able neutralize/bind the HCl emitting during thermal disintegration of PVC according to the formula CaO + 2HCl = CaCl2 + H2O. Content of the oil shale ash in the PVC composite material is 0,5-60%. The invention also includes product made from the said composite material. |
