Principle And Usage Of Abrasive Paper For Water-sanding
Water abrasive paper also plays a big role in the production of models, such as eliminating the water outlet of the parts, polishing the missing parts of the parts cut from the runner, etc. Sometimes, fine wet abrasive paper can also be used to remove the gloss of the spray paint. Remove the oxidation layer of the metal parts and make the metal parts emit their original luster. Oil on water sandpaper can make wooden models show a soft luster.
The production principle of water sandpaper
Water sandpaper is made by sticking silicon carbide particles on a paper base with a water-resistant adhesive.
Scope of application: It has the characteristics of water processing, the high surface finish of the workpiece, and no dust and water pollution during water sandpaper operation.
Characteristics of water sandpaper
Sandpaper has a considerable effect on model making, avoiding water outlets of parts, and polishing missing notches cut from the runner, and it can also be polished with fine sandpaper, removing the hydrolysis layer and restoring the original metal luster. Oil polishing can make the surface smooth and shiny.
Water-resistant sandpaper has a wide range of particle size distribution. ranging from P60 to P5000. For products, the finest dry sandpaper is about P1000. Water sandpaper is especially suitable for fine-grained, high-precision polishing. Compared with other precision processing materials, fine water-resistant sandpaper has a high-cost performance and a low price. It can be used for both wet and dry grinding, with wide adaptability
Water sandpaper usage method
Water sandpaper is used in water or with added water, not for dry grinding. All sandpapers must be cut into blocks of about 60x30 millimeters for use. Generally, grind the stone and find a flat surface. If the stone surface is not flat enough, you can buy iron sandpaper to make it flat.
Iron sandpaper has relatively large particle sizes and is used for rough grinding. It must be dry around. Water sandpaper has small particles and is used for fine grinding. It is used with added water. Start from the coarsest and the smallest number of water sandpaper is the coarsest.
Usually start with 320, grind back and forth dozens of times in one place, then 600, then 800, and so on. Continuously use water and sandpaper up to 5000. Every time you change the sandpaper, you must thoroughly rinse it with water. Clean the stone and use a toothbrush to scrub off the dirt in the concave and the corners before you use finer sandpaper.
