Principle and Usage of Abrasive Paper for Water-Sanding

Many items in life need to be polished with water abrasive paper to take shape, such as leather, wood, metal, cups, etc. Now let's introduce some knowledge about water abrasive paper.

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 water 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 dioxide particles on paper base with water-resistant adhesive.

Scope of application: It has the characteristics of water processing, high surface finish of 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, polishing missing notches cut from the runner, and can also be polished with fine sandpaper, removing the hydrolysis layer and emitting 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, the fine water-resistant sandpaper has a high cost performance and low price. It can be used for both water 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 a relatively large particle size and is used for rough grinding. It must be dry ground. 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 for dozens of times in one place, then 600, then 800, and so on. Continuously use water sandpaper up to 5000. Every time you change the sandpaper, you must thoroughly rinse with water, clean the stone, and use a toothbrush to scrub off the dirt in the concave and the corners before you can use finer sandpaper.
