When using highly saturated red iron oxide (red ochre), there was a problem that color separation was likely to occur, making the skin look dull and causing uneven coloring. The present invention relates to a composition comprising the following components (A), (B), (C), and (D): (A) Titanium oxide (B) Zinc oxide (C) An inorganic red pigment having a hue angle of 0 to 72°, a value V of 2 to 7, and a chroma C of 5 to 7.5 as specified in the Munsell color system when measured in specular reflection (incident angle 0°, integrating sphere light reception). (D) Silica anhydride A makeup cosmetic containing

The present invention relates to the field of ceramics and preparation methods thereof, and in particular to a ceramic with a three-dimensional concave-convex texture and a preparation method thereof, wherein the glaze is inlaid with stone, the raw materials of the green body comprising, by weight, the following components: 20-30 parts of porcelain clay, 10-12 parts of quartz, 30-40 parts of feldspar, 20-30 parts of kaolin, 6-8 parts of spodumene, 6-8 parts of dolomite, and 4-6 parts of carboxymethyl cellulose glue, and the raw materials of the glaze comprising, by weight, the following components: 26-28 parts of feldspar, 20-24 parts of calcium carbonate, 18-22 parts of ball clay, 8-10 parts of kaolin, 20-22 parts of quartz stone, 2-4 parts of bone ash, 2-4 parts of ochre yellow colorant, and 2-4 parts of red iron oxide. The fired ceramic glaze presents an amber green color with convex real stone texture, concave white green body color lines, and black coloring texture attached to the glaze, thereby having rich and three-dimensional color texture.

This invention discloses a pipeline steel plate with excellent surface quality and its manufacturing method, characterized by producing 8-16mm thin-gauge pipeline steel plates using a continuous casting slab + controlled rolling process. The specific chemical composition is: C: 0.06±0.03%; Si: 0.18±0.07%; Mn: 1.60±0.25%; Al: 0.03±0.02%; Nb: 0.040±0.015%; Ti: 0.015±0.008%. The slab is heated in a walking beam furnace at a tapping temperature of 1140~1170℃, with a total furnace time of 8~10 min / cm. The furnace air-fuel ratio is 0.50~0.70, and the roughing descaling roller speed is ≤1.2m / s. The slab is formed through a two-stage rolling process of roughing and finishing. The roughing descaling process has ≥3 passes, and the finishing process has ≥2 passes. The initial thickness for finishing rolling is 3.5H~4.5H (H is the finished thickness of the steel plate). The initial finishing rolling temperature is 920~980℃. The steel plate is air-cooled after rolling. The yield strength of the steel plate is 380~480MPa, and the tensile strength is 480~560MPa. The steel plate has a continuous and complete iron oxide scale structure, which reduces the probability of red iron oxide scale formation. The steel plate also has excellent corrosion resistance.
