Embodiment Construction

[0022] In the present invention, the artificial marble in the mold (or inner mold) is directly irradiated with microwaves of a specific frequency (between 300 and 1120 MHz, typically 915 ± 10 MHz) that have good penetrability to artificial marble, causing the internal The frictional movement between molecules converts microwave energy into kinetic energy and finally heat energy, so that the artificial marble is heated rapidly and the curing time is greatly shortened.

[0023] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be described in further detail below in conjunction with specific embodiments and with reference to the accompanying drawings.

[0024] It should be noted that, in the following two embodiments, artificial marble blocks are used as an example for illustration. The artificial marble here refers to calcium carbonate, silicon dioxide or aluminum hydroxide powder as the main filler, unsa...

Abstract

The invention provides a method for curing artificial stone through microwave heating. The method comprises the steps that A, raw materials of the artificial stone are injected into a mold (or inner mold) after being burdened, and artificial stone which is not cured is formed; B, the artificial stone and the mold (or inner mold) are put in a microwave curing cavity together; C, the artificial stone in the microwave curing cavity is heated through microwaves and made to be completely cured, and the frequency of the microwaves ranges from 300 MHz to 1,120 MHz; D, the microwave curing cavity is opened, and artificial marble and the mold (or inner mold) in the microwave curing cavity are taken out; E, demolding is carried out, and the cured artificial marble is released out of the mold (or inner mold). The individual microwave curing cavity is designed, and the large-size artificial stone can be cured fast through the characteristic that the microwaves with the specific frequency of 300 MHz to 1,120 MHz are large in penetration depth.

Description

technical field [0001] The invention relates to the field of microwave application technology, in particular to a method for curing artificial stone by using microwave heating. Background technique [0002] Artificial stone refers to a decorative material with natural marble and granite patterns made of binders, thick and thin fillers and admixtures through a certain process. Among them, artificial marble is the most widely used artificial stone variety. It mostly uses calcium carbonate, silicon dioxide or aluminum hydroxide powder as the main filler, and unsaturated polyester or other high molecular polymers as the binder. , has many characteristics of natural marble, and because it can be adjusted manually, it has various colors, good flexibility, no obvious connection treatment, strong overall sense, and colorful, with ceramic luster, high hardness, not easy to damage, corrosion resistance, High temperature, and very easy to clean. [0003] The conventional production p...
