[0002] Latex or rubber chemical products are common in industrial production and daily life. The glue raw materials used to produce and process such products are prone to form bubbles inside the glue during the processing. Due to the high viscosity of the glue, it is difficult for the bubbles to escape from the glue on their own. In order to ensure the quality and appearance of the product, the glue raw materials need to be degassed during the processing of such products.
