1、水泥型人造石塑UV板這種人造石塑UV板是以各種水泥作為粘結劑，砂為細骨料，碎大 理石、花崗石、工業(yè)廢渣等為粗骨料，經配料、攪拌、成型、加壓蒸 養(yǎng)、磨光、拋光而制成，俗稱水磨石。仿大理石uv板
1, cement type artificial stone plastic UV board this artificial stone plastic UV board is to cement as binder, sand as fine aggregate, large pieces of marble, granite, industrial waste residue as coarse aggregate, the ingredients, mixing, forming, pressing steam curing, polishing, and made, commonly known as the terrazzo.
2、聚酯型人造石塑UV板這種人造石塑UV板是以不飽和聚酯為粘結劑，與石英砂、大理 石、方解石粉等攪拌混合，澆鑄成型，在固化劑作用下產生固化作 用，經脫模、烘干、拋光等工序而制成。我國多用此法生產人造石塑UV板。不飽和聚酯光澤好、顏色淺，可調成不同的鮮明顏色，這種樹脂 粘度低、易于成型、固化快，可在常溫下固化。

2, polyester based artificial stone plastic UV board this artificial stone plastic UV board is to unsaturated polyester as binder, and quartz sand, marble, calcite powder mixing, pouring and molding, under the effect of curing agent produced curing, demoulding, drying, polishing process and made. Our use of this method for producing artificial stone plastic UV board. The unsaturated polyester has good luster and light color, which can be adjusted into different bright colors. This kind of resin has low viscosity, easy molding, fast curing, and can be cured at room temperature.

3、復合型人造石塑UV板這種人造石塑UV板是以無機材料和有機高分子材料復合組成。 用無機材料將填料粘結成型后，再將坯體浸漬于有機單體中，使其 在一定條件下聚合。對板材而言，底層用低廉而性能穩(wěn)定的無機材 料，面層用聚酯和大理石粉制作。
3, composite artificial stone plastic UV board this artificial stone plastic UV board is based on inorganic materials and organic polymer composite. When the filler is formed by the inorganic material, the body is immersed in the organic monomer, and the blank is polymerized under certain conditions. On board, the inorganic material is low and stable performance in the bottom, the top layer is made of polyester and marble powder production.
4、燒結型人造石塑UV板這種人造石塑UV板是將長石、石英、輝石“、方解石粉和赤鐵礦粉 及少量高嶺土等混合，用泥漿法制備坯料，用半干壓法成型，在窯 爐中用 1000 C左右的高溫燒結而成。
4 and sintered artificial stone plastic UV board this artificial stone plastic UV board is the mixture of quartz, feldspar and pyroxene, calcite powder and hematite and small amount of kaolin, billets prepared by slurry method, semi dry pressing molding method, in the kiln furnace with about 1000 C high temperature sintering and.
