Introduction
Rubber expansion joint is also called: flexible rubber expansion coupling, rubber soft connection, and soft rubber joint, rubber compensator, rubber shock hose, rubber shock reducer, is one kind of high elasticity, high air tightness, medium resistance and weather ability pipe fittings.
Rubber expansion joint consists of outer rubber, inner rubber, framework layer, and reinforcing bar and flange. Relying on rubber¡¯s special performances as long range elasticity, air impermeability, medium, climate and radiation resistance, rubber expansion couplings can reduce the vibration and noise of pipeline, and can be caused by the temperature change of heat bilges cold shrink compensation effect.
Production progress
1. Raw material: we never use reclaimed raw rubber, rubber is imported from USA. Before used, raw material should be tested, including physical test and some chemical experiment to test the hardness and so on;
2. Rubber pretreating and ingredients;
3. Milling: first, rubber plastication, second, rubber mixing, we will add rubber compounds, like sulfurzing reagent, surfactant, softener, stabilizer, foaming agent and some special compounds, at the same time, rubber will be extruded into plates, cut, produce 45 degree angle. The plates cannot directly be used, they should be cooled about 24 hours;
4. Molding: it will cost much time;
5. Vulcanizing: the largest vulcanizing tank in Asia ø5000*15000, right time, temperature, pressure is very important;
6.Test and experiment: these tests should be done, hydraulic test, resistance to vacuum, displacement of the performance, rubber physical properties, thickness and the strength and other quality test;
7. Package: out package the free of fumigation wooden case; inside package: plastic film and textile membrane.
