How to Control the Temperature during Drying after Weaving the Braided Hydraulic Rubber Hose?

How to control the temperature during the production of braided high-pressure hoses and hydraulic hoses in the process of drying after dipping the glue? The temperature in our drying room is about 45 degrees. Drying for 1 hour, there will still be bubbles after vulcanization. Think about the problem of drying? And there is water in the bubbles? How is drying more appropriate? Listen to our professional introduction from Industrial Hose Manufacturer.

Recommendations 1. The temperature of the drying room is about 45 degrees. Drying for 1 hour is a little less. Generally, drying takes about 4 hours.

Recommendation 2. Our drying conditions are 70 ~ 80 ℃, 2 ~ 3 hours.

Recommended 3. Hydraulic Rubber Hose should be air-dried for 1 hour at normal temperature after dipping the glue, and then can be dried in the drying room at 45 degrees to 60 degrees for no less than 4 hours. Dry, not dry inside, vulcanized, foamed and delaminated.

Recommendation 4. Dry for 4 hours at 50-60°C.

Recommendation 5. My drying is on-line drying, a three-meter hot drying tunnel, a temperature of 160 degrees, a speed of 15 meters per minute, and it can be dried completely. I use gasoline glue.

Recommendation 6. I haven't tried high temperature and short time drying.

After you wind it up, apply the glue online and then dry it, then press the outer glue, and the adhesion reaches the standard. This process is worth promoting. Saved the drying room and a large number of hanging hose racks, improved production efficiency, changed the intermittent process to a continuous process, just added a high temperature oven, I have the opportunity to ask you about it.

I only saw continuous drying production in the infrared baking oven in the past, but the tube embryo stays in the oven for 3-4 minutes, unlike you only staying for 12 seconds.

Suggestion 7. We generally dry at 50-60 ℃ for 12 hours. We use hydrosol slurry.

Recommendation 8. Online drying in a short time, it is not enough to get the temperature of the oven alone. A blower must also be installed. The three conditions for evaporation are: temperature, the speed of air flow, the liquid surface area, and the liquid surface area cannot be changed, but It can change the speed and temperature of air flow. The wind speed is too fast, the temperature cannot go up, and the speed is too slow to achieve the effect, so the wind speed is the key. When designing the oven, you should also consider the wind direction and exhaust, because the solvents are flammable. Pay attention to safety!

Recommendation 9. Adhesion of high pressure hose

We use water-soluble glue, as mentioned above, 70-80 degrees, 12 hours. completely fine. Now we are using the glue directly without drying, pressing the outer layer while passing the glue. The cost is lower than water-soluble glue.

The above is the method introduced by the supplier of SAE Hydraulic Rubber Hose for the temperature of the braided hydraulic hose after soaking the glue. I hope it can help everyone.
