Embodiment Construction
[0021] The present invention will be further described below in conjunction with specific embodiment:
[0022] Example 1-Example 6, comparative analysis of whiteness, coagulation time and demoulding time under different proportions of raw material components, see Table 1.
[0023] Table 1
[0024]
[0025] In the above embodiments, the whiteness of the granulated blast furnace slag powder is 86-88, the particle size is less than 0.045 mm, and the strength is S75 or S95. The particle size of plaster of paris is less than 0.080mm, and the main component content is CaSO 4 ≥88%, whiteness not less than 65.
[0026] The preferred raw material components are: granulated blast furnace slag powder: plaster of paris: water = 1:0.7:0.26. At this time, the initial setting time is the shortest and the demoulding is the fastest, which is conducive to large-scale production and improves production efficiency.
[0027] When being used to make handicrafts, the specific operation steps o...

Abstract
The invention relates to the sculpture material field, in particular to a sculpture ground slag material and a molding method thereof. The sculpture ground slag material and the molding method thereof are characterized in that granulated blast-furnace slag powder, plaster and water are mixed by weight ratio of 1: (043-1) : (0.2-0.3). specific operation steps include the following steps: 1) mixing the granulated blast-furnace slag powder and the plaster in complete formula amount, adding water in the stirring process, fully stirring for 3-5 minutes, and making moldable materials; 2) injecting the moldable materials into a mold, swinging for 2-5 minutes, still standing for 10-20 minutes, and then demolding after molding; 3) placing products after demolding in a venting environment for at least more than 2 hours before transport. Compared with the prior art, the sculpture ground slag material and the molding method thereof have the advantages that characteristics of white appearance and high self strength of granulated blast-furnace slag are fully utilized, and particularly in outdoor large-scale landscape sculptures, the sculpture ground slag material and the molding method thereof enable the sculptures to have outstanding characteristics of high strength and waterproof performance and the like in long time, and reduces cost by 30%.
Description
technical field [0001] The invention relates to the field of sculpture materials, in particular to a slag powder material for sculpture and a molding method thereof. Background technique [0002] At present, people widely use gypsum as a sculpture material, and gypsum has the advantages of stable chemical properties, easy molding, and moderate hardness. The main component of gypsum is calcium sulfate dihydrate (Ca〔SO 4 〕·2H 2 O), also known as dihydrate gypsum, water gypsum or soft gypsum, monoclinic crystal system, the crystal is plate-like, usually in the form of dense block or fiber, with white or gray, red, brown, glass or silky luster, friction The hardness is 2, the density is 2.3g / cm 3 . [0003] When used to make large handicrafts, in order to improve the strength of the plaster model, the following methods are usually used: [0004] 1. Heating and dehydrating natural dihydrate gypsum under steam conditions can produce α-hemihydrate gypsum, also known as autocla...
