Beschreibung
Zusammenfassung:	FIELD: production of cable flexible PVS, pipes and sheet building materials. SUBSTANCE: PVC is mixed with mineral filler with temperature increased up to 25-65 C. Prior to mixing, water is introduced in the amount of 2-8% of filler mass. Then, stabilizer suspension in plasticizer is introduced into mixture and the latter is heated up to 80-120 C with stirring. EFFECT: higher efficiency. 1 tbl Использование: в производстве кабельного пластиката, а также труб, листовых строительных материалов. Сущность: смешение ПВХ с минеральным наполнителем осуществляют до 20 - 65°С, а перед смешением вводят воду в количестве 2 8% от массы наполнителя. Затем вводят суспензию стабилизатора в пластификаторе и смесь перемешивают при нагревании до 80 120°С. 1 табл.
