Abstract

The invention discloses an expandable resin raw material microwave pre-foaming machine and a raw material pre-foaming method, and belongs to the technical field of plastic processing equipment. The expandable resin raw material microwave pre-foaming machine comprises a rack, a stirring cylinder, a microwave generator and a silicone rubber heating plate, the stirring cylinder is horizontally fixed in the rack, the outer bottom of the stirring cylinder is bonded with the silicone rubber heating plate, and the microwave generator used for heating the interior of the stirring cylinder is arranged at the top of the stirring cylinder. The expandable resin raw material microwave pre-foaming machine has the beneficial effects that the microwave generator and the silicone rubber heating plate are combined for heating, a medium is integrally heated, other heat transfer media are not needed, and therefore the speed is high, the efficiency is high, the period is greatly shortened, and energy consumption is reduced; and meanwhile, the expandable resin raw material microwave pre-foaming machine is free of noise and toxic gas and liquid emission and is beneficial to environmental protection.

Description

technical field [0001] The invention relates to the technical field of plastic processing equipment, and more specifically relates to a microwave pre-expansion machine for expandable resin raw materials and a method for pre-expansion of raw materials. Background technique [0002] Steam is one of the necessary conditions for the pre-foaming of expandable resin raw materials. In addition, there is an electric heating method for pre-foaming of expandable resin raw materials. However, electric heating is slow in heating up and the temperature is not easy to control, so steam is used for pre-foaming. Foaming and molding of models. Steam is obtained by means of steam boiler, steam generator, electric heater or electromagnetic. [0003] However, the use of electric heaters has high power and high operating costs; the heating temperature of electric heating tubes is not easy to control, and the production efficiency is low; the use of steam boilers and steam generators is a high e...
