preparation example Construction

[0032] The preparation method of the porcelain fuse case of the present invention comprises the following steps:

[0033] 1) According to the number of parts by mass, each raw material is weighed;

[0034] 2) Using the wet ball milling process to prepare mud in the ball mill, control the mass content of particles with a size less than or equal to 10 μm in the mud to be 75-90%;

[0035] 3) Pass the mud through a 140-200 mesh sieve and remove iron, use a certain production process to shape the green body, and fire it at 1180-1250 ° C to form a fuse porcelain shell. .

[0036] The invention uses waste materials recovered from the production of isostatic electric porcelain, and uses feldspar and additives at the same time, which overcomes common problems such as loose body and cracking, easy burning and red absorption of products, poor tensile strength of products, etc., and ensures the quality of the products. , and passed the verification to meet the technical requirements of ...

Embodiment 1

[0040] 1) Weigh and take raw materials according to the mass ratio, including 85 parts of waste materials, 13 parts of potassium feldspar, 0.3 parts of sodium carbonate, and 1 part of additives, including 0.4 parts of binder sodium carboxymethyl cellulose and 0.6 parts of A15 dispersant;

[0041] 2) Put it into a ball mill, use the wet ball milling process to prepare mud, and control the mass content of particles with a size less than or equal to 10 μm in the mud to 75%;

[0042] 3) The mud is passed through a 140-mesh sieve and iron is removed. The prepared mud is sprayed as normal, the green body is pressed, and fired at 1180°C to produce a qualified fuse porcelain shell product.

Embodiment 2

[0044] 1) Weigh and take raw materials according to the mass ratio, including 90 parts of waste materials, 11 parts of potassium feldspar, 0.4 parts of sodium hydroxide, 1.2 parts of additives, including 0.48 parts of binder sodium carboxymethyl cellulose, and 0.72 parts of A15 dispersant ;

[0045] 2) Put it into a ball mill, use the wet ball milling process to prepare mud, and control the mass content of particles with a size less than or equal to 10 μm in the mud to 85%;

[0046] 3) The mud is passed through a 180-mesh sieve and iron is removed. The prepared mud is sprayed as normal, the green body is pressed, and fired at 1200°C to produce a qualified fuse porcelain shell product.

Abstract

The invention relates to a blank formula of a fuse ceramic shell using a waste material recycled from isostatic pressing electroceramics and a preparation method thereof. The blank comprises following components in parts by mass: 85-90 parts of waste material recycled from isostatic pressing electroceramics, 10-15 parts of feldspar, 0.3-0.5 part of water reducing agent and 0.8-1.2 parts of additive. The fuse ceramic shell is prepared from the raw materials through steps of grinding, sieving, deironing and so on. Due to adoption of the waste material recycled from isostatic pressing electroceramics, the water reducing agent and additive as well as the feldspar as the fluxing agent, the performance of the ceramics is effectively guaranteed, the costs of the raw materials and manufacture are lowered, the performance requirements of the ceramics are met, and excellent effects of the ceramics are achieved.

Description

technical field [0001] The invention belongs to the field of ceramic manufacturing, and relates to a formula and a preparation method for fuse porcelain shell blanks produced by using isostatic piezoelectric ceramics to produce recycled waste materials. Background technique [0002] Porcelain shells of high and low voltage current-limiting fuses generally use ceramic products with high aluminum content as the outer insulator, which is the main component of fuse products. In an increasingly competitive market environment, porcelain outer insulators require excellent performance and moderate prices. The products mainly use natural minerals as raw materials. As the disposable resources of mines in my country become less and less, the manufacturing process, material properties, and overall performance of the products are greatly affected. Overcoming its source of raw materials, improving process performance and reducing material cost has become a top priority. [0003] The commo...
