Crosslinking and curing baking system and oven cooling method thereof

Abstract

This invention relates to a crosslinking reaction and curing baking system and its oven cooling method. The oven is located outside a cleanroom, and clean air from the cleanroom is introduced into the oven cavity through cooling pipes. After the baking process, the temperature is rapidly reduced, and simultaneously, high-temperature exhaust gas is directed out of the cleanroom via hot air pipes to avoid contaminating the cleanroom environment. This system can be applied to the post-molding baking treatment of materials such as FKM (fluororubber), FFKM (perfluoroelastomer), and epoxy resin, resulting in a more complete crosslinking reaction, reduced volatile residues, and improved heat and chemical resistance. This invention offers advantages such as rapid cooling, maintaining product surface cleanliness, and reduced equipment setup and maintenance costs.

Claims

1. A crosslinking reaction and curing baking system, characterized in that it comprises: A cleanroom equipped with air meeting international standards from ISO Class 1 to ISO Class 9, with a temperature range of 15°C to 30°C; an oven located outside the cleanroom, wherein at least the oven's internal cavity inlet is located on the exterior wall of the cleanroom, through which air enters the oven's internal cavity from the cleanroom; a cooling duct connecting the cleanroom and the oven's internal cavity, allowing clean air from the cleanroom to flow into the oven's internal cavity; and a hot air duct connecting the oven's internal cavity to the external environment, used to exhaust high-temperature exhaust gases from the oven's internal cavity to the outside; thereby, after the oven's baking process is completed, the internal temperature of the oven can be rapidly reduced by introducing clean air from the cleanroom, while maintaining the cleanliness of the cleanroom.

2. The crosslinking reaction and curing baking system as described in claim 1, wherein, The cooling duct draws cleanroom air through vents in the outer wall of the cleanroom. A regulating valve is installed on the cooling duct to control the flow rate of cleanroom air introduced into the oven cavity.

3. The crosslinking reaction and curing baking system as described in claim 2, wherein, The cooling duct includes a blower.

4. The crosslinking reaction and curing baking system as described in claim 3, wherein, The inner cavity entrance of the oven is located on the front side of the oven and is closed by a door panel. The front side of the oven is embedded in an opening on the outer wall of the cleanroom, so that the front side of the oven is located inside the cleanroom.

5. The crosslinking reaction and curing baking system as described in claim 1, wherein, The oven includes at least one tray with brackets inserted into the oven cavity on both sides of the tray, and one of the surfaces of the tray that contacts the brackets is coated with Teflon.

6. A method for cooling a cross-linking reaction, curing, and baking oven, comprising: (a) Place the workpiece to be cross-linked and / or cured into an oven located outside a cleanroom; (b) After the baking process is completed, clean air from inside the cleanroom is introduced into the oven cavity through a cooling pipe. The cleanroom has an air temperature range of 15°C to 30°C, which meets international standards for Class 1 (ISO Class 1) to Class 9 (ISO Class 9); and (c) At the same time, the hot air from inside the oven is exhausted to the outside of the cleanroom through a hot air pipe to quickly reduce the temperature inside the oven cavity and prevent the cleanroom from being contaminated by exhaust gas.
