Description

Technical Field

[0001] This application relates to the field of Buddhist bead making technology, and more specifically, it relates to a type of incense ash Buddhist bead and its manufacturing method. Background Technology

[0002] Buddhist prayer beads are commonly known as bracelets, hand beads, hand rosaries, etc. In current technology, Buddhist prayer beads are mostly made of various materials such as metal, stone, bone, fruit pits, bamboo, and wood. Among them, wood is the most widely used due to the abundance of high-quality tree species, rich and diverse textures, colors, and aromas, as well as its large quantity.

[0003] Incense ash is the residue left over from burning incense in temples. Most of this ash is dumped and buried, with only a small amount used to make incense ash products (such as small Buddha statues and prayer beads). The long-term dumping and burying of large quantities of incense ash can easily have adverse effects on soil and water sources. Furthermore, existing incense ash products lack antibacterial, wear-resistant, and corrosion-resistant properties, especially incense ash prayer beads. Prolonged wear can easily cause surface wear, and contact with skin oils, sweat, and skincare products can easily lead to bacterial growth. Based on the above, this application provides an incense ash prayer bead and its manufacturing method. Summary of the Invention

[0004] To address the current shortcomings of low recycling and reuse rates of incense ash and poor antibacterial, wear-resistant, and corrosion-resistant properties of incense ash products, this application provides an incense ash prayer bead and its manufacturing method.

[0005] Firstly, this application provides a type of incense ash prayer bead, employing the following technical solution: A type of incense ash Buddhist prayer beads is made by applying incense ash glaze to the unglazed body by brushing and then firing it. The raw materials for the green body, by weight, include 40-50 parts of high white clay, 10-23 parts of modified incense ash, 2-4 parts of sintering aid, and 48-60 parts of deionized water. The incense ash glaze raw material, by weight, includes 10-15 parts modified incense ash, 0.1-0.2 parts grinding aid, and 40-50 parts deionized water; Preferably, the high-white mud is obtained by compounding kaolin and quartz powder in a mass ratio of 3-9:1.

[0006] Preferably, the modified incense ash is prepared by the following method: Modified incense ash is obtained by mixing incense ash, functional powder and modified liquid in a mass ratio of 1:0.05-0.1:2-3, ultrasonically dispersing and drying.

[0007] Preferably, the incense ash is pre-washed incense ash.

[0008] Preferably, the functional powder comprises tourmaline powder, nano zinc oxide, and nano silver in a mass ratio of 1-3:1-3:0.1.

[0009] Preferably, the modified liquid comprises sophorolipid, polyether silicone oil and ethanol solution in a mass ratio of 1:1:20-24.

[0010] Preferably, the sintering aid comprises sodium tripolyphosphate and sodium polyacrylate in a mass ratio of 5-7:1.

[0011] Preferably, the grinding aid comprises sodium silicate and isopropanolamine in a mass ratio of 3-5:1-2.

[0012] Preferably, the raw materials for the incense ash glaze may also include potassium feldspar, clay, etc.

[0013] Secondly, this application provides a method for making incense ash prayer beads, which adopts the following technical solution: A type of incense ash Buddhist prayer beads and its manufacturing method, comprising the following manufacturing steps: S1. By weight, add deionized water to high white clay and stir to mix evenly to obtain high white clay slurry. Add modified incense ash and sintering aid to high white clay slurry, continue stirring and mixing evenly, and then make round bead-shaped blanks. S2. Place the billet into the kiln and heat it to 600-800℃ at a heating rate of 2-5℃ / min. After holding it at this temperature for 2-3 hours, cool it down to room temperature at a cooling rate of 7-12℃. S3. Use a water-replenishing pen to apply clean water to the blank and inspect and select qualified blanks with no defects on the surface. S4. By weight, add the modified incense ash and grinding aid to deionized water, grind and mix evenly to obtain incense ash glaze. Apply incense ash glaze to qualified blanks by brushing and place them in a kiln. Heat the blanks to 1200-1400℃ at a heating rate of 12-18℃, keep them heated for 2-10 hours, and then cool them in the kiln to obtain incense ash prayer beads.

[0014] Preferably, the bead-shaped blank in step S1 is made by pinching or carving or by using a mold.

[0015] Preferably, the glazing amount in step S4 is 580-700 g / m³. 2 .

[0016] In summary, this application has the following beneficial effects: This application uses a mixture of kaolin and quartz powder as the main materials to prepare high-white clay slurry. By adding modified incense ash, the fineness of the high-white clay slurry can be effectively increased, the defect rate of incense ash prayer beads can be reduced, and the finished incense ash prayer beads can be made smoother. By adding a sintering aid made of sodium tripolyphosphate and sodium polyacrylate, the density of the prepared green body can be improved, which helps to achieve high density and uniform sintering at a lower temperature, reduces the shrinkage rate of the final sintered incense ash prayer beads, and further reduces the defect rate of incense ash prayer beads.

[0017] This application uses a composite of tourmaline powder, nano zinc oxide, and nano silver as functional powders. Tourmaline powder emits far-infrared rays beneficial to the human body, promoting metabolism and providing significant health benefits. The combined use of nano zinc oxide and nano silver has a significant bactericidal effect. By controlling the ratio and total amount of the three, stable compatibility with incense ash can be achieved. A modified liquid is prepared using a composite of sophorolipid, polyether silicone oil, and ethanol solution. In the modified liquid, the incense ash and functional powders are ultrasonically modified, which helps to improve the dispersion, wettability, and surface activity of the modified incense ash, and improves the compatibility and bonding between the modified incense ash and the high-white clay. This, in turn, increases the density of the prepared body and the bonding between the body and the glaze layer. The resulting incense ash prayer beads have low sintering shrinkage, low defect rate, and excellent antibacterial, wear-resistant, and corrosion-resistant properties.

[0018] This application uses sodium silicate and isopropanolamine as a grinding aid. Modified incense ash, grinding aid and deionized water are mixed and ground to obtain incense ash glaze. The obtained incense ash glaze has stable fluidity and good adhesion. It can be perfectly combined with the surface of the body and has a low sintering shrinkage rate, resulting in a high yield of incense ash Buddhist beads.

[0019] In summary, the incense ash prayer beads prepared in this application have a high incense ash content, realizing the reuse of incense ash and reducing the preparation cost. The incense ash contains important chemical components for ceramic glazing, such as silicon dioxide, calcium oxide, potassium oxide, and sodium oxide. By compounding and adding functional powders, the final incense ash prayer beads can exhibit a unique color. Detailed Implementation
