How to ensure the organic silicone adhesive achieves the target curing degree by matching the line speed of the coating machine and oven length for high-temperature PTFE tape?
This article covers how to match coating machine line speed and oven length to ensure organosilicone adhesive reaches target curing degree for high-temperature PTFE tape. Core matching principle: total residence time t_total = effective oven length L ÷ line speed v must be no less than minimum required cure time. Obtain cure characteristics via DSC or adhesive cure tests establishing "temperature — minimum cure time" relationship. Equivalent cumulative cure model: divide oven into zones, calculate ti=Li/v and tcure(Ti), ensure ∑(ti/tcure(Ti)) ≥1. Calculation procedures: set temperature zones with lengths Li and temperatures Ti; set line speed v, calculate each zone's residence time and contribution ratio; iterate until total ≥1 (safety margin 1.1-1.2 recommended).
