Application of Coated Abrasives in Furniture Industry
As we all know, the application of coated abrasives in modern industry is very common. At present, coated products are mostly concentrated in the woodworking market, metal grinding and surface treatment market, and the automotive industry. For the traditional woodworking market, the manufacturing problems of today's abrasive tool manufacturers have been basically solved, the characteristics of their products are gradually the same, and the quality difference and top brands are gradually narrowed. Sandpaper for wood include dry sanding, wet sanding and mechanical sanding.
Dry sanding: Use sandpaper or sanding
disc for grinding. It is suitable for grinding hard and brittle paints. The
disadvantage is that a lot of dust will be generated during the operation,
which will affect the environmental sanitation. Wet sanding: sand with
sandpaper dipped in water or soapy water. Water grinding can reduce wear marks,
improve the smoothness of the coating, and save sandpaper and labor. However,
when spraying the lower layer of paint after water grinding, first, the lower
layer of paint must be applied after the water-grinding layer is completely
dry, otherwise the paint layer will easily whiten. Another highly absorbent
substrate should not be water milled. Mechanical grinding: During large-scale
construction, in order to improve work efficiency, mechanical grinding methods
can be used, such as electric grinding machines (disc type, vibration type).
When we get a piece of white blank, we
first rough sand it to remove the small edges, corners, burrs and other traces
left on the furniture during processing. It’s important for wood industry to
select what grit sandpaper for cabinets. The dust from sanding is easy
to embed in the temples, so it is necessary to brush the dust while sanding
until the surface is flat and smooth. After blowing and wiping, use different
types of sandpaper to polish it separately. After many times of polishing, the
furniture seems to be very smooth in every part.
One of the rules of furniture sanding is to
use a sanding sponge block (sponge sand or wood block), because
furniture sanding without a sanding block cannot guarantee uniform sanding
strength. For flat surfaces, the sanding block should be cushioned; a sanding
block without a cushion is inflexible, so the grit from the sanding block can
scratch the wood surface during sanding. For curved surfaces, your best bet is
a thick foam pad or sponge covered with sandpaper. These fillers change their
shape according to the curvature of the wood, resulting in a consistent and
even sanding force.Then perform fine grinding. The purpose of this level of
grinding is to eliminate the sand marks left in the rough grinding process, and
the purpose is to keep improving. At this stage, when grinding the corners and
edges of the object, the force should be appropriate, the action should be
light, and the original round or square outline must be maintained. As the last
water-grinding process, so that the furniture produced is closer to the
tradition.
