3 results about "Iron oxide yellow" patented technology

This application belongs to the technical field of building repair materials, and particularly relates to a red brick restoration agent and its restoration method. The red brick restoration agent is composed of the following components by weight: 30-40 parts polymer dry powder mortar, 8-12 parts aldehyde-free alcohol adhesive, 0.1-0.3 parts iron oxide red powder, 0.05-0.15 parts iron oxide yellow powder, and 8-12 parts clean water. This restoration agent, through the synergistic effect of "nano-mineral color matching + polymer micro-reinforcement + aldehyde-free alcohol adhesive bonding," enables the repair layer to be "integrated" with the old brick in four dimensions: visual appeal, mechanical properties, durability, and environmental friendliness, achieving "original appearance restoration and lifespan extension."

This utility model relates to the field of iron oxide yellow production technology, and discloses a feeding device for producing low-sulfur iron oxide yellow. The device includes a support frame, a weighing mechanism on the inner side of the support frame, a pad at the bottom of the support frame, and multiple support legs fixedly connected to the top left side of the pad. The tops of the multiple support legs are fixedly connected to the same storage tank, and the storage tank has an anti-blocking mechanism inside. The weighing mechanism includes a fulcrum rod, which is fixedly connected to the middle of the inner side of the support frame. A balance rod is rotatably connected to the outer wall of the fulcrum rod. In this utility model, when the weights at both ends of the balance rod are equal, a trigger switch is activated to close the electric valve, and cylinder two is activated, causing the balance rod to rotate 90 degrees. Subsequently, cylinder one is activated to push the moving block to slide, causing the opening and closing plate to move to both sides of the material container, allowing the material inside the container to fall downwards, thus achieving a quantitative feeding process.

This invention discloses a method for preparing arsenic-cadmium lattice mineralized and immobilized silicate mineral materials based on mechanochemical ball milling and its application. The invention aims to solve the technical problems of poor arsenic and cadmium immobilization and ineffective immobilization in existing silicate mineral materials. Preparation method: 1. Mix iron oxide yellow and serpentine evenly to obtain an iron-serpentine composite silicate mineral material; 2. Place the iron-serpentine composite silicate mineral material in a ball mill jar and ball mill it at a controlled speed to obtain an arsenic-cadmium lattice mineralized and immobilized silicate mineral material. Application: This invention involves adding the arsenic-cadmium lattice mineralized and immobilized silicate mineral material to polluted water or soil. This invention uses a mechanochemical method to form a surface bond between iron manganese oxides and serpentine, constructing a composite interface with multiple synergistic effects, improving the adsorption performance of cadmium and arsenic, and significantly promoting the diffusion and immobilization process of heavy metal ions into the serpentine lattice.
