Embodiment Construction

[0008] The specific structures and characteristics known in the following schemes will not be described here.

[0009] The formula mainly uses 27 parts of potassium feldspar, 14 parts of quartz powder, 3 parts of Syria, 4 parts of limestone, 16 parts of wrought talc, 3 parts of spodumene, 1 part of barium carbonate, 10 parts of high-strength billet, 6 parts of ordinary billet, carboxylate 0.2 parts of methylcellulose (OM6-1). The finished glaze slurry is made through a series of typical glaze preparation processes:

[0010] ① Measure the moisture content of various raw materials first, and then make accurate ingredients according to the formula and the amount required for production.

[0011] ② Put the prepared materials into the ball mill, and perform ball milling according to the ratio of material: ball: water = 1:1.5:1.

[0012] ③After 29 hours of ball milling, stop the machine for pulping, and go through normal procedures such as sieving and removing iron before it can b...

Abstract

The invention relates to a raw material formula of wire-post type sand-coating glaze, and relates to processing powder used for preparing ceramic product glaze. With the raw materials, electroceramics with higher mechanical properties and dielectric properties can be prepared. A purpose of the invention is achieved through the following measures: the raw material formula of wire-post type sand-coating glaze is characterized in that the glaze comprises substances of, by mass: 27-31 parts of potash feldspar, 14-18 parts of quartz powder, 3-6 parts of Xu earth, 4-7 parts of limestone, 16-20 parts of calcined talcum, 3-5 parts of spodumene, 1-3 parts of barium carbonate, 10-15 parts of a high-strength blank material, 6-12 parts of a common blank material, and 0.2-0.5 parts of carboxymethyl cellulose (OM6-1). Compared with prior art, the technical scheme provided by the invention is characterized in that with the formula, the prepared glaze is advantaged in uniform ceramic sand distribution, no sand stacking or sand lacking phenomenon, and firm ceramic sand adhesion. After a sand-coating process, the strength is improved by 20%. The glaze is convenient to use, and can be used as wire-post type sand-coating special-purposed glaze.

Description

technical field [0001] The present invention relates to a processed powder ready to be used as a glaze for the manufacture of ceramic articles. Background technique [0002] Electric porcelain is generally made of solid insulating materials, installed between conductors of different potentials or between conductors and grounding components, and is a device that simultaneously functions as electrical insulation and mechanical support. Although the structure and shape of different types of insulators are quite different, they are all composed of two parts: the insulating body and the connecting fittings. The insulator whose insulating body is porcelain is called electric porcelain. Glaze is a layer of glassy substance covering the surface of porcelain. The purpose of glazing mainly has the following points: to improve the mechanical strength of porcelain parts (20-40%), and to increase the range, the expansion coefficient of glaze is slightly smaller than the expansion of po...
