The invention discloses a Romel jade-based graded mass production makeup and protection integrated cosmetic raw material and an application thereof, is a divisional application of a parent case patent (2025119339307), and belongs to the technical field of cosmetics. Aiming at the problems that the existing tremolite jade does not have an exclusive makeup raw material processing technology, the performance of the raw materials is not uniform and large-scale mass production cannot be realized, the content of a color-making element (Mn / Cr) is safe hard red lines, the fiber interweaving degree is used as a core grading basis, and natural structural pink fluorescent tremolite jade (such as powdered mutton fat jade) is used as an attribute reference basis. By adopting the processes of pretreatment, primary screening of coloring elements, core grading of fiber interweaving degree, fluorescence-assisted judgment, directional prototype-assisted screening, grading purification, layering re-carving and grading finished product adaptation, a dumb and non-astringent skin feeling is realized through grading surface modification, and four-level products of star occupational level, star daily level, public high-end level and public basic level are prepared. The method is suitable for full-scene application, and the mass production feasibility and the product performance stability are both considered.

The present application relates to the technical field of the production of sanitary ceramics, and particularly relates to a low-temperature sanitary ceramic green body and a preparation method therefor, and a low-temperature sanitary ceramic. The green body comprises the following raw materials in percentages by mass: 10-20% of ball clay, 10-25% of high-alumina porcelain stone, 5-15% of spodumene tailings or microcline, 25-45% of porcelain clay, 0-10% of potassium feldspar, 5-20% of tremolite, and 5-20% of boron-containing waste glass. Problems in controlling the regularity of mass-produced products are overcome by introducing natural microfibrous / nanofibrous tremolite to replace a calcium- and magnesium-containing raw material, i.e., dolomite, performing low-temperature sintering to form a system comprising multiple mineral phases such as sodium / calcium feldspar, using a key technique capable of achieving steady-state control over the deformation rate during sintering, and broadening the sintering range of a low-temperature sintering green body. Moreover, a low-temperature sintering ceramic slurry is endowed with better forming performance, thereby improving the tensile strength of both wet and dried green bodies, solving quality problems such as susceptibility to cracking during the forming and firing processes of a green body caused by poor suspension properties of a slurry, and meeting the process requirements of mass production.
