Introduction to the empirical conversion formula of ring pressure strength and side pressure strength
In the process of making the carton, the ring pressure strength of the base paper and the edge pressure strength of the finished carton are inextricably linked. Long-term production practices and laboratory testing have also validated this relationship. Cardboard edge compressive strength (ECT) is generally the edge compression strength of corrugated board, in units of cattle per meter (N/m). The paper's ring compression strength (RCT) mainly refers to the transverse compressive strength of boxboard and corrugated paper, in units of cattle per meter (N/m). The side pressure strength (ECT) of corrugated board is related to the ring pressure RCT of boxboard and corrugated paper. According to daily experience, the calculation formula of different corrugated shapes is as follows: 1. Side pressure strength (ECT) of single corrugated cardboard = RCT + paper RCT + corrugated paper RCT × 楞 rate 2. Side pressure strength (ECT) of double corrugated board = paper RCT + paper RCT + core paper RCT + first layer corrugated paper RCT × corresponding rate + second layer corrugated paper RCT × corresponding rate % This is just an empirical conversion formula for single corrugated and double corrugated. For different shapes, we also summarize another set of experience conversion formulas for ACB type corrugated and ACB type single and double corrugated, as follows: 1. Type A --- Side slab strength of single corrugated board (ECT) = 1.0 (face paper RCT + paper RCT + corrugated paper RCT × 楞 rate) 2. Type C---Side pressure strength (ECT) of single corrugated cardboard = 1.1 (face paper RCT + paper RCT + corrugated paper RCT × 楞 rate) 3. Type B---Side Compression Strength (ECT) of single corrugated cardboard = 1.1 (face paper RCT + paper RCT + corrugated paper RCT × 楞 rate) 4. AB type - double corrugated board edge strength (ECT) = face paper RCT + 1.1 × paper RCT + 1.05 × core paper RCT + A corrugated paper RCT × corresponding rate + B corrugated paper RCT × corresponding rate × 1.1 5. BC type - double corrugated board edge strength (ECT) = 1.1 × (face paper RCT + paper RCT + core paper RCT + A corrugated paper RCT × corresponding 楞 rate + B corrugated paper RCT × corresponding 楞 rate)
