Description
Сначала ввод т 56% каучука и другие ингредиенты и после подъема температуры до 95°С добавл ют остальной каучук, выгрузив смесь при 100°С.First, 56% of rubber and other ingredients are added and after the temperature rises to 95 ° C, the remaining rubber is added, unloading the mixture at 100 ° C.
Пример 4. Резиновую смесь готов т по предлагаемому режиму при общем объеме заправки 215 л, что составл ет 85% свободного объема камеры резиносмесител . Вначале ввод т 64% каучука и другие ингредиенты , и после подъема температуры смеси до 105°С добавл ют остальной каучук , выгрузив смесь при 110°С.Example 4. A rubber mixture is prepared according to the proposed mode with a total filling volume of 215 liters, which is 85% of the free volume of the rubber mixer chamber. First, 64% of rubber and other ingredients are added, and after raising the temperature of the mixture to 105 ° C, the remaining rubber is added, discharging the mixture at 110 ° C.
Физико-механические показатели резин, приготовленных по предлагаемому и известному способам представлены в таблице.Physico-mechanical properties of rubber, prepared by the proposed and known methods are presented in the table.
Предлагаемый способ смешени позвол ет на 20% увеличить загрузку камеры резиносмесител и, как видно из таблицы, резины по предлагаемому способу приготовлени резиновых смесей обладают лучшими физико-механическими показател ми в сравнении с известным способом: предел прочности при разрыве увеличиваетс не менее, чем на 3-12%, устойчивость к действию многократного раст жени повышаетс не менее, чем на 10%, относительное удлинение - не менее, чем на 7%, а остаточное удлинение уменьшаетс не менее, чем на 20%.The proposed mixing method allows for a 20% increase in the load of the chamber of the rubber mixer and, as can be seen from the table, the rubber according to the proposed method for the preparation of rubber mixtures have better physical and mechanical indicators in comparison with the known method: the tensile strength at break increases by no less than 3 -12%, resistance to the effect of repeated stretching increases by no less than 10%, relative elongation by no less than 7%, and residual elongation decreases by no less than 20%.
