High-resilience sponge technology adopts cold-molding technology to form high-resilience cold-cured polyurethane foam, which has excellent mechanical properties (high resilience, low hysteresis loss); high compression load ratio, so it has a significant sitting comfort Type; excellent fatigue resistance; feel similar to latex surface; good air permeability and flame retardant properties. At the same time, due to the short production cycle, high efficiency, and low energy consumption, it has now replaced the traditional thermally cured polyurethane foam. In addition to these, high resilience sponges have some advantages: good shock resistance and flexibility; good tear strength; easy adjustment of hardness; excellent resilience and flexibility; excellent foam replasticity (after being changed in shape) It can be restored to its original shape immediately, with good elasticity); it can be made into any shape. So high resilience sponge has many applications in life. It also has a wide range of uses in the home furniture industry, aircraft industry, toy industry, automobiles, motorcycles, trains, high-end sporting goods industry (mainly sports protective gear) and other industrial fields. Among them, there are mainly motorcycle seat cushions, car headrests, backrests, sofa cushions, mattresses, high-end car seats, sofa seats, office seats, toys, massage equipment accessories, high-density balls, and one-shot foams of various shapes.
So in the production process, you may encounter such a problem, the machine sinks badly, what should I do?
First of all, analyze the reasons: Why does the sinking phenomenon occur? First, because the gel speed is too slow, increase the amount of catalyst correspondingly to increase the gel speed; second, the late stability of the silicone oil has deteriorated, so increase it appropriately at this time Dosage; Third, it may be due to incorrect flow ratio or uneven mixing. In this case, pay attention to the operation; fourth is caused by PPGG water intake; fifth is the proportion of black material, too high proportion will also cause such problems.
There are also some ways to alleviate the sinking problem: replace T-9 with T-12; replace diethanolamine with glycerol; re-adjust the mold temperature.
