Embodiment 1

[0009] Embodiment 1. A ceramic bare-pack fired multi-layer stacked release agent is formulated from 40 kg of 100-140 mesh quartz particles, 60 kg of 32-100 mesh quartz particles, 2 kg of peach gum and an appropriate amount of water. First, Dissolve the peach gum with 15-20kg of water, then add the two kinds of quartz particles, and then adjust an appropriate amount of water to form a thin paste.

Embodiment 2

[0010] Example 2, a ceramic bare-pack fired multi-layer stacked release agent, consisting of 55 kg of quartz particles of 100-140 mesh, 45 kg of quartz particles of 32-100 mesh, 0.5 kg of sodium carboxymethylcellulose (CMC) and an appropriate amount of It is formulated with water, first dissolve sodium carboxymethylcellulose (CMC) with 5-10kg of water, then add the two kinds of quartz particles, and then add an appropriate amount of water to make a thin paste.

Embodiment 3

[0011] Embodiment 3, a kind of bare-packed and fired multi-layer stacked release agent of ceramics, calcined Al by 100-140 mesh 2 o 3 50 kg of granules, 50 kg of quartz granules of 32-100 mesh, 0.8 kg of sodium carboxymethyl cellulose (CMC) and an appropriate amount of water are added. First, sodium carboxymethyl cellulose (CMC) is mixed with 12-16 kg of water dissolved, then add the quartz particles and Al 2 o 3 Granules, add appropriate amount of water to adjust to a thin paste.

[0012] The release agent described in embodiment 1-3, the weight ratio of the two kinds of particles of 100-140 mesh and 32-100 mesh and the external addition weight ratio of peach gum or sodium carboxymethylcellulose (CMC), and the addition of water The amount, so that the thin consistency of the release agent is suitable for the needs of the construction method.

Abstract

The invention relates to an insulator for bare-packing and sintering ceramics to be stacked in a multi-layered manner and an application method thereof. The insulator comprises the following raw materials in parts by weight: 35-60 parts of quartz particles with 32-100 meshes, 40-65 parts of calcined Al2O3 or quartz particles with 100-140 meshes and 0.5-2 parts of peach gum or carboxyl methyl cellulose (CMC). The application method comprises the following steps during the preparation: firstly, dissolving the peach gum or the carboxyl methyl cellulose by using water with a weight ratio of 6-20 times, then adding the proportioned other raw materials, and finally, adding an appropriate amount of water to mix into thin paste. When in use, the insulator is sprayed, coated or brushed on the surfaces of stacked parts of ceramic tire products; and after the insulator is naturally aired, the same shape or different shapes of a plurality of layers of or a plurality of ceramic tire products are vertically stacked on sintered kiln furniture on a same plane to be sintered, and the sintering temperature is 1200-1280 DEG C. After the ceramics are sintered, viscose compositions in the ceramics aredecomposed and evaporated, and the quartz particles and the calcined Al2O3 particles are only remained among the ceramic tire products and can not be melted or bonded with ceramic tires, so that the purpose of dividing and separating the vertically-stacked and sintered ceramic tire products is achieved.

Description

technical field [0001] The invention relates to a ceramic bare-pack fired multi-layer laminate release agent and a method for using the same. Background technique [0002] When ceramic products are fired, they are generally fired in a sagger set or single-layer (single) naked on the firing kiln furniture. Therefore, there are disadvantages such as low firing efficiency and high energy consumption. Contents of the invention [0003] The present invention is to provide a ceramic bare-pack fired multi-layer stacked release agent, which aims to realize the vertical stacking of multi-layer or multiple ceramic tire products on the same surface after it is sprayed, painted or brushed on the surface of the ceramic product. The firing is carried out on the flat firing kiln furniture, so as to improve the firing efficiency, save energy and reduce consumption. [0004] The present invention comprises raw materials in the following weight ratios: 35-60 parts of 32-100 mesh quartz pa...
