In order to produce a foamed molded article formed with a hollow part therein,

1) injecting raw materials (foamed particles and binders / or expanded particles, binders and reinforcing materials) supplied from the hopper (mixing and feeding) of the extruder into the extruder (cylinder and screw);

2) extrusion of the raw material passing through the extruder into the inside of the molding machine in which the hollow portion is stamped;

3) forming the mixed raw material in the molding machine;

4) extruding the molded foam at a low speed and supplying the upper end of the movable conveyor installed in front of the molding machine;

5) drying and curing the supplied foamed molding through a drying apparatus installed in a conveyor;

6) withdrawing the dried, cured foamed molding through a drawer running at a suitable speed;

7) cutting the drawn foamed molding to a desired length through a cutter;

  It is a basic process to obtain a completed foam molding through the manufacturing process of.

In particular, in the B) manufacturing process,

It is more preferable to further include a heating device in a hopper, a cylinder, and a molding machine, which is a component of the step-by-step process, to continuously heat the raw material, thereby to evaporate moisture contained in the raw material, and to shorten the drying rate of the foamed molding.

If so, the method for producing a foamed molding using a device equipped with a heating window for each step is described in detail as follows. (Hereinafter, a hopper equipped with a heating device is referred to as a 'heating mixer'.)

The raw materials (foamed particles and binder / or foamed particles, binder and reinforcing materials) are put into a heat mixer at a combination ratio of physical properties to be prepared,

By heating and mixing the above, water in the raw material (mainly a binder) is partially evaporated.

The mixed and heated raw materials are forward-transmitted while being kneaded, heated, and compressed by a cylinder and a screw in an extruder equipped with a thermostatic heating device.

The raw material inside the cylinder is extruded and supplied to the molding machine installed in front by the rotation of the screw in the cylinder,

By gradually passing the raw material through the hole (cross section) of the molding machine equipped with the heating device,

The foamed molding with the desired shape is continuously drawn to the top of the forward movable conveyor.

In this process, the molding machine is provided with a heating device to continuously heat the raw material introduced into the molding machine to sustain evaporation of moisture contained in the raw material.

The continuous molded foam is discharged to the upper end of the conveyor

Rapid drying and curing of the foamed molding through the drying device installed on the top of the conveyor.

(At this time, the drying apparatus may be a drying apparatus configured by using at least one drying method among heating, hot air, and microwave irradiation methods.)

The dried and cured foamed product is taken out using a drawer,

The drawn foamed molding is cut to a desired length using a cutter to produce a finished ceramic foamed molding.

(The biggest reason for the above-mentioned overlapping heating device in step is that in the actual production of the foamed molding, it is possible to quickly dry the moisture in the raw material to act as the closest cause of mass production of the product.)

On the other hand, in order to manufacture the foamed molding in individual units,

General molding method,

Inject the raw material (foam particle and binder / or foam particle, provider and reinforcing material) into the inside of the molding machine,

The above is crimped | bonded and heated by the press which attached the upper mold | type.

The prepared foamed product is taken out from the molding machine,

By using a drying device (heating, hot air, microwave irradiation, consisting of one or more drying methods in parallel) made of a stand-alone, using a method for producing a completed foam molded by curing, or

The foamed product drawn out from the molding machine is discharged to the upper end of the movable conveyor, and dried and cured while gradually moving through a drying apparatus (composed at least one drying method among heating, hot air, and microwave irradiation) installed at the upper end of the conveyor. To produce a completed foam molding.

(In this manufacturing method as well, it is preferable to mix and heat in advance using a heat mixer to partially evaporate the water in the raw material, and then to feed the raw material into the molding machine.)

The method for producing a ceramic foam molding has been described above.

In the case of the foamed molded article prepared by adding the reinforcing material,

Due to the weight of the reinforcement mixed in the main raw material,

Since the weight of the foamed molding increases,

By forming the hollow part inside the foamed molding,

It is possible to produce a ceramic foam molding with improved performance such as sound insulation and heat insulation while avoiding excessive weight increase.

In addition, the hollow portion may vary in shape and size, and may be manufactured by applying various hollow portions having a desired shape and size to a hollow portion of a single layer, a hollow portion of a double layer structure, a cylindrical structure, a square pillar structure, and the like ( 1).

However, even in the case of ceramic foam moldings manufactured without using a reinforcing material as a raw material, super lightweight properties are provided.

Of course, the effect of dramatically improving sound insulation and insulation is excellent.

In addition, a coating material of various inorganic materials emitting far-infrared rays or coated colored sodium silicate cement on the surface of the foamed molded article produced in the above various methods and forms,

It is possible to provide a highly usable foamed molded article having a wider range of use by adhering a finish including paper, fabric, synthetic resin film, fiber powder locking, etc. to the surface.

In addition, in addition to the manufacturing method described above, a variety of manufacturing methods of the foam molding is already known,

Also in the case of a ceramic foamed molded article manufactured through a manufacturing method other than the above-described manufacturing method,

Of course, it can be manufactured by configuring the hollow part according to the present invention,
