Abstract
The invention relates to a coated body preparation device and a preparation method, powder material of a coated body, a coated body blank and a preparation method. A coated body blank comprising the following mineral components in weight percent: 25-45 wt% of high white ball clay, 20-40 wt% of water-washed kaolin, 2-10 wt% of quartz, 5-10 wt% of corundum, 10-30 wt% of albite, 10-30 wt% of potassium feldspar, 2-5 wt% of talcum and 0.3-1.0 wt% of water reducer, wherein the water reducer is formed by combining one or more of sodium tripolyphosphate, sodium silicate, sodium metasilicate, sodium hexapolyphosphate and polycarboxylic acid. The coated body blank comprises the following chemical components in percentage by weight: siO (SiO) 2 58～65wt％、Al 2 O 3 27～32wt％、CaO0.2～0.5wt％、Fe 2 O 3 0.5～1.0wt％、MgO1～3wt％、K 2 O2～4wt％、Na 2 O2～4wt％。
Description
Technical Field
The invention belongs to the technical field of amber-like ceramics, and particularly relates to a coated body blank, a preparation method, coated body powder and a coated body preparation device.
Background
Amber is a very unique precious stone material that has unique characteristics and values of brilliant and varied colors, original ecology and natural aesthetics, historic and cultural associations, etc., making amber a precious stone in jewelry, artwork and ornaments. However, as a precious stone, the color of amber and the appendages (insects, plants, etc.) are the main reasons for giving the value, and these things need to be formed through the fossil action for a very long time, and the forest environment for forming amber is relatively scarce, thus the scarcity of amber is caused, and the demand is high, so that amber is touted in the jewelry and ornament industries, finally, the price of amber on the market is higher than that of some rare precious stones, and the decorative effect of amber cannot be widely popularized to the public.
Therefore, the research of the artificial amber to replace the natural amber has great practical significance, and an artificial amber substitute with natural amber decorative effect and good performance becomes a goal which is constantly pursued by people, for example, publication No. CN200959937Y discloses a manufacturing method of an artificial amber stone solid panel, which comprises the following technological steps: an artificial amber Dan Shiti panel is made up of artificial stone and waterThe transparent resin products which are distributed in the artificial stone and contain animal and/or plant specimens, or artware, characters or souvenirs with different sizes and shapes are orderly or unordered.
