specific Embodiment approach 1

[0006] Specific embodiment one: a kind of ore glass bead used for road marking, glass bead is optical glass bead, and described glass bead is by mass ratio: 40 parts of sandstone, 28~32 parts of barite, 18.5~22.5 parts 1 part diamond, 2.5 parts calcium boronite, 2 parts feldspar, 4 parts Glauber's salt and 2 parts smithsonite.

[0007] The process method of the present invention: qualified raw materials are mixed into batch materials after being crushed, screened and measured, and the batch materials are melted into molten glass in the melting furnace. The flow of glass liquid flows out from the drain plate hole, and the stream falls vertically into the centrifuge. The centrifuge rotates at a high speed, and the glass liquid is forced to be thrown out through the small holes on the peripheral wall of the centrifuge with the help of centrifugal force, and then forms beads after passing through the high temperature zone. The glass beads are annealed to eliminate or reduce the th...

specific Embodiment approach 2

[0009] Embodiment 2: The difference between this embodiment and the ore glass beads for road marking described in Embodiment 1 is that the particle size of the glass beads is 100-850 microns.

specific Embodiment approach 3

[0010] Embodiment 3: The difference between this embodiment and the ore glass beads used for road marking described in Embodiment 1 or Embodiment 2 is that the refractive index of the glass beads is 1.62-1.72.

Abstract

The invention relates to mineral glass beads for road markings, which relates to optical glass beads and solves the problems of low refractive index and poor reflective brightness of the current glass beads for the road markings. The mineral glass beads for the road markings are the optical glass beads, wherein the glass beads are prepared from the following components in part by weight: 40 parts of sandstone, 28 to 32 parts of barite, 1835 to 22.5 parts of diamond, 2.5 parts of datolite, 2 parts of feldspar, 4 parts of mirabilite and 2 parts of smithsonite. The mineral glass beads can be widely used in road markings of airfield runways and high-level roads.

Description

technical field [0001] The invention relates to an optical glass bead. Background technique [0002] Glass beads for optics are a special glass product in the glass industry. It has certain chemical stability, high mechanical strength, good electrical insulation, integrity, uniformity, good fluidity, and does not contain any toxic heavy metals. It is safe And no pollution. Its most unique performance is that it has the original transparency of glass and the regression of directional reflection. However, the existing glass beads used for road markings have low refractive index and poor reflective brightness. Contents of the invention [0003] The object of the present invention is to solve the problems of low refractive index and poor reflective brightness of existing glass beads used for road markings, thereby proposing a kind of ore glass beads used for road markings. [0004] An ore glass bead used for road marking, the glass bead is an optical glass bead, the glass b...
