Preparation process of ultrathin rock plate

Abstract

The invention provides a preparation process of an ultrathin rock plate. The process comprises the following steps: S1, preparing raw material powder, namely putting corundum, quartz, potassium feldspar, albite and polycrystalline mullite fibers into a ball mill according to a ratio, and carrying out ball milling; S2, powder distribution: after magnetic separation for iron removal and homogenization, adding a toughening agent and an activating agent into the powder in proportion, drying, spraying and granulating in a drying sprayer to form a mixture, and then feeding the mixture into a distributor for distribution; S3, high-pressure compression molding, specifically, conveying the powder obtained in the step S2 into a ceramic plate mold through a conveying belt, carrying out compression molding through a 500-ton air pressure vibration molding machine, and manufacturing a green body of the ceramic rock plate; S4, spraying glaze; S5, ink-jet printing; S6, coating a bottom slurry of the brick; S7, firing specifically, firing the ceramic rock plate; and S8, carrying out detecting, sorting and warehousing. The preparation process of an ultrathin rock plate is high in toughness, attractive in appearance and not prone to embrittlement.

Description

technical field [0001] The invention relates to the technical field of preparation of ceramic thin plates, in particular to a preparation process of ultra-thin rock plates. Background technique [0002] The ultra-thin ceramic sheet has the characteristics of "big, thin, light, and beautiful": super-large specifications, up to 1200cm×3600cm, and a single board area of ​​4.32m 2 , which is currently the largest porcelain architectural decorative plate in the world. It can be widely used in cabinets, home panels, integral bathrooms, and spray-painted background walls. It has good integrity, small seams, and is easy to clean; ultra-thin size, thickness only It is 3.0mm, which greatly saves resources and energy. It can be combined with other materials to make products with special materials, such as composite lightweight door panels, acid and alkali resistant laboratory table tops, hospital antibacterial wall operation table tops, outdoor furniture, etc. ; Ultra-light weight, on...

Problems solved by technology

[0003] However, because the ultra-thin rock slab is ultra-thin and ceramics are fragile, special shock-absorbing settings are required during transportation and handling to ensure that the rock slab is intact, and rock slabs are required on contact surfaces such as special curved walls. It has high toughness. Therefore, it is necessary to design a preparation process for ultra-thin rock slabs with high toughness, beautiful appearance, and not easy to be brittle.
