Embodiment 1

[0033] The composition ratio of the composition of white cement is:

[0034] 40% by weight of silicate raw material, 20% by weight of quartz sand, 15% by weight of bauxite, 20% by weight of gypsum, 2.5% by weight of potassium feldspar, and 2.5% by weight of albite feldspar.

[0035] After the white cement composition is mixed with water, it will start to solidify within 10-14 minutes, and will completely solidify within 30-50 minutes. Generally speaking, it will completely solidify within 30-40 minutes in summer, and in winter It takes 50 minutes to fully set. But compared with the performance of domestic white cement in the past, it has been improved a lot. The performance parameter comparison table of the following domestic white cement and white cement of the present invention:

Embodiment 2

[0038] The composition ratio of the composition of white cement is:

[0039] 35% by weight of silicate raw material, 25% by weight of quartz sand, 10% by weight of bauxite, 25% by weight of gypsum, 2% by weight of potassium feldspar, and 3% by weight of albite feldspar.

[0040] After the white cement composition is mixed with water, it will start to solidify within 10-14 minutes, and will completely solidify within 30-50 minutes. Generally speaking, it will completely solidify within 30-40 minutes in summer, and in winter It takes 50 minutes to fully set. But compared with the performance of domestic white cement in the past, it has been improved a lot. The performance parameter comparison table of the following domestic white cement and white cement of the present invention:

[0041]

Embodiment 3

[0043] The composition ratio of the composition of white cement is:

[0044] 45% by weight of silicate raw material, 15% by weight of quartz sand, 20% by weight of bauxite, 15% by weight of gypsum, 3% by weight of potassium feldspar, and 2% by weight of albite feldspar.

[0045] After the white cement composition is mixed with water, it will start to solidify within 10-14 minutes, and will completely solidify within 30-50 minutes. Generally speaking, it will completely solidify within 30-40 minutes in summer, and in winter It takes 50 minutes to fully set. But compared with the performance of domestic white cement in the past, it has been improved a lot. The performance parameter comparison table of the following domestic white cement and white cement of the present invention:

[0046]

[0047] And the preparation method of the composition of white cement of the present invention is made up of the following steps:

[0048] (1) Grind the raw material with a ball mill, and ...

Abstract

The invention discloses a composition of white cement and a preparation method thereof. The composition consists of (a) 35-45 percent by weight of silicate raw material, (b) 15-25 percent by weight of quartz sand, (c) 10-20 percent by weight of bauxite, (d) 15-25 percent by weight of plaster, (e) 2-3 percent by weight of potassium feldspar and (f) 2-3 percent by weight of albite. The preparation method consists of the following steps of: (1) grinding the raw materials by using a ball mill; (2) mixing and stirring; (3) drying; and (4) packaging in a fully sealing way. The invention has the beneficial effects that: the relation performance such as initial setting time, final setting time, strength, expansion coefficient and the like of white cement is enhanced greatly, the production cost of an enterprise is reduced, the working efficiency of production is increased, the dependence of a manufacturer on imported products during production is overcome, the manufacturability during production is satisfied, the production cost of the enterprise is reduced greatly during production, and the economic benefit of the enterprise is increased.

Description

technical field [0001] The invention relates to a composition of white cement and a preparation method thereof. Background technique [0002] In the glue binding of electric porcelain production, white cement will be used for glue binding. At present, there is no white cement that can meet the use standard in China, and it cannot meet the initial setting time, final setting time, strength and expansion coefficient. requirements for production up to now. [0003] In the past, white cement imported from abroad has been used in the production industry of electric porcelain, fuses, circuit breaker poles and electric porcelain parts, but the glue binding is only an important link in the whole production. 1. Long initial setting time, 2. Longer final setting, 3. Large expansion coefficient, not suitable for fuses, circuit breakers and some electric ceramic adhesives. The amount of imported white cement is not large, and the purchase cycle is long. White cement also has great res...
