Silicone tableware vulcanizing oven

Silicone tableware vulcanizing oven

Inner box size: H1550*W840*D1200mm (can be customized according to requirements)

The role of the secondary vulcanization box: When the silicone rubber is vulcanized by peroxide, the decomposition of the peroxide initiates the reaction of the polymer, and the formation of a low molecular compound such as benzene and benzoic acid in the rubber will affect the mechanical properties of the rubber. The crosslink density is not sufficient. To further react, it is necessary to increase the time or increase the temperature, which takes up the time of the mold and the vulcanizer and affects the efficiency. In the second-stage vulcanization, the peroxide is actually very small, mainly by increasing the cross-linking by oxygen. Therefore, the oven should be equipped with an air blower and the glue should not be stacked too densely. Low-molecular substances such as HF released during the vulcanization of the fluororubber will hinder the cross-linking of the rubber, and the high temperature will also be released. Corrosion of metal parts, so also requires two-stage vulcanization. In addition, the fluororubber may also undergo a cyclization reaction to produce a fluorine-containing ring, thereby further improving its heat resistance.

The oven is a forced air convection heating type secondary vulcanization device, which has the dual exhaust gas discharge effect, and can be equipped with a hot-loadable loading and unloading truck, which is beneficial to improve quality and work efficiency.

This product is suitable for rubber and synthetic rubber products, such as: rubber tube, rubber belt, sealing strip, small parts, synthetic rubber wire, silicone insulating sleeve, etc.

Secondary vulcanization box appearance:

The design of this precision oven exterior structure: according to the ergonomics and space design, the appearance is beautiful, the operation is convenient, and the reduction is very limited.

Less station area.

1. The outer casing is made of t=1.2mm thick cold-rolled plate, and the surface is sprayed with high-temperature spray paint (environmental outdoor powder) to prevent rust and corrosion.

2. The secondary vulcanization box is integrated (single door, two doors, three doors, four doors), and the high temperature sealing strip is added around the door panel, which makes the furnace high temperature gas

Does not leak a good insulation effect.

3, the shelf tray is welded by stainless steel square tube, each layer shelf can be taken out independently, and 4 universal joint brake activity wheels are installed at the bottom of the oven.

And equipped with four positioning foot cups (foot cups can adjust the height of the oven and the ground).

◎ Secondary vulcanization tank liner:

The silicone oven has a special air-structure design that ensures the temperature uniformity inside the cabinet during baking.

Energy savings.

1. The inner inner liner is made of 1.2mm thick SUS304 stainless steel mirror panel. It has anti-rust and anti-corrosion functions and is used for several years.

After wiping, it is still as clean as new.

2, high temperature silicic acid insulated rock wool with a density of 130K and a thickness of 100mm around the liner; it has very good thermal insulation effect, and the cabinet

The surface temperature is within 50 ° C, which greatly reduces the cost of using the oven.

3. Built-in special designed circulating horizontal air duct, the air volume can reach 2000m3 per hour, and can be cycled more than 7500 times per hour to make the furnace temperature more uniform.

◎ secondary vulcanization box

The stainless steel fin-type heating tube is installed at the air outlet of the oven wind impeller, and the heat is evenly distributed. The heating tube terminal is externally placed in the oven, and the heating tube is spaced 55 mm apart from the heating tube to avoid the compact connection of the honeycomb heating tube. The resulting short circuit between the phases is insufficient to avoid potential danger. The heating tube terminal opening is on the back side of the oven, which avoids the heat transfer to the electrical components caused by the opening at the top and reduces the service life of the appliance (the temperature of the general appliance is below 45 ° C).

◎ Secondary vulcanization chamber circulating air system and exhaust system:

1. The top is equipped with a 0.75KW wind-driven motor platform: 10.5-inch centrifugal wind impeller (guaranteed sufficient air volume). The high-volume circulation design mode compensates for the temperature difference caused by the oven during ventilation (cycle times: 7500 times / H).

2, with air inlet and outlet, so that the turbid gas inside the oven is discharged to the outside, into the fresh air, reduce the turbid gas discharged from the product in the oven, so that the surface color of the product is more realistic, and the air flow regulating valve can be adjusted at any time. The amount of gas.
