Abstract
A kind of ceramic composition, by 40～85% chemical gypsums (phosphogypsum, fluorgypsum, mirabilite gypsum, salt gypsum, titanium gypsum, flue gas desulfurization gypsum etc.), 10～40% yellow phosphorus slags (or slag, slag, wollastonite etc.), 50～20% fluorites or/and Sodium Silicofluoride and an amount of pigment and glaze form.The present invention utilizes the chemical industry waste residue to make main starting material, adopt existing technology and equipment, calcining temperature only needs 800～1100 ℃, and the ceramic that burns till has very high physical and mechanical property and good decorative effect, has very remarkable economic efficiency and social benefit.
Description
The present invention relates to a kind of ceramic composition, particularly a kind of chemical gypsum pottery is applicable to and makes finishing material.
Existing ceramic composition as finishing material generally adopts clay, feldspar, quartz, talcum etc. to make main starting material, through being mixed and made into slip, sieves, dehydration, compression moulding, makes finished product in technologies such as 1200～1300 ℃ of calcinings down, coolings; Owing to need a large amount of tonerdes etc., cause the waste in soil (arable land); Because the calcining temperature height consumes higher heat energy, the product cost height.On the other hand, a large amount of industrial residues do not obtain utilizing, difficult treatment, and cause the pollution of environment.
Purpose of the present invention aims to provide a kind of with the chemical gypsum pottery composition of chemical industry waste residue as main main raw material.
Content of the present invention is a kind of chemical gypsum pottery, and its feature part is to form (weight %) and is:
40～85% chemical gypsums, this chemical gypsum can be one or more the mixtures in phosphogypsum, fluorgypsum, mirabilite gypsum, titanium gypsum, flue gas desulfurization gypsum or the salt gypsum,
10～40% silico-calcium materials, this silico-calcium material can be one or more the mixtures in yellow phosphorus slag, slag, slag or the wollastonite,
5～20% fluorites are or/and Sodium Silicofluoride.
The composition preferably (weight %) of content of the present invention is:
60～85% chemical gypsums, this chemical gypsum can be one or more the mixtures in phosphogypsum, fluorgypsum, mirabilite gypsum, titanium gypsum, flue gas desulfurization gypsum or the salt gypsum,
10～30% silico-calcium materials, this silico-calcium material can be one or more the mixtures in yellow phosphorus slag, slag, slag or the wollastonite,
5～15% fluorites or/Sodium Silicofluoride.
Can also be added with the mineral dye that accounts for gross weight 0～7% in the content of the present invention, this mineral dye can be the oxide compound of elements such as antimony, lead, silicon, boron, chromium, cobalt, manganese, iron.
Can also glaze be arranged at the ceramic body surface daub on a wall in the content of the present invention, so that there is the pattern of various colors on the ceramic surface.
Compared with prior art, the present invention has following characteristics:
(1) without clay, utilize the main raw material(s) (accounting for about 90%) of work potteries such as reluctant chemical industry waste residue-chemical gypsum and slag, slag, yellow phosphorus slag or wollastonite, turn waste into wealth, help the protection of environment, social benefit and remarkable in economical benefits;
(2) production process and equipment and prior art basically identical, but calcining temperature only needs 800～1100 ℃, and energy consumption reduces greatly, low production cost;
(3) physical and mechanical property of ceramic finished product is good, good product quality.
Below by embodiment the present invention is further described:
