Forming method.
Background technology
3DP (Three Dimensional Printing) printing technique is also referred to as rapid shaping technique, this method tool
Have the advantages that shaping speed is fast, with low cost, device space utilization rate is high.3DP printing technique is by conventional planar drawing
Redefining of design pattern, completes model and is changed to three-dimensional from conceptual design, realizes for design being used for accurate adding
Work manufactures, and makes model file be changed into the purpose of the part with specific dimensions or product, and greatly shortens product development cycle.
To environmental protection and advocate natural pursuit with people, the sandstone cultural brick with sandstone as aggregate, due to texture
Bright and colourful, health environment-friendly is rich in dicoration again, enjoyed in recent years and pursue in numerous areas.By 3DP printing technique, can
Printing speed goes out complex-shaped, structure diversification, and the sandstone product that mechanical strength is high, refractory ability is strong.
At present, there is more being combined with artificial marble, artificial hilllock stone, limestone, high strength gypsum, ceramic base on the market
The different size powder such as thing, starch based complex be consumptive material sandstone product, be used for process modeling, finishing furred ceiling, surface float
The field such as carving and mobile phone A pp scanning cartoon artware.With the change of the market demand, people require to get over to the color and luster of sandstone product
Come higher.However, there is a problem of the sandstone providing in China market that color variety is few more, lighter color and not bright-coloured.By rock
The uneven restriction of ore deposit distribution of color, the colored sand that there is multiple color mixes phenomenon, and this directly governs 3DP printing speed skill
Art is in the application of full-color sandstone dye field.
There is uneven, the easy reunion of Dispersion on surface, stability difference in sandstone product and see that light easily takes off in conventional dyes reagent
The shortcoming of color.Although impregnation technology small investment of production equipment, technique and flow process are simple, and goods cost is low, causes product
Acid and alkali-resistance, corrosion-resistant and weatherability are poor.If being directly exposed to open air, at short notice discolouration phenomena can occur, or even
Crackle or fracture occur and reduces product quality.Slug type full-color sandstone dyestuff does not then meet the requirement of low cost.
