Mill, water mill, oil abrasion, wax mill and toothpaste polishing etc..Dry grinding is divided into corase grinding, plain grinding and fine grinding again, wherein corase grinding is usually in Qian Chu
For going the wolline of Wood-removing device openpore, scar, glue mark and pencil print etc. dirty when reason；And plain grinding be usually wrapped up wood particle or
Emery cloth, the sand paper of vulcanite polish to big plane, and effect levelling in this way is preferable；Fine grinding is then generally used for Puttying, upper envelope
It closes in the processing of each road middle layer after paint, colorant match and complementary color.Water mill is to dip in clear water (or suds) polishing, water mill energy with waterproof abrasive paper
Polishing scratch is reduced, the smoothness of coating, and laborsaving, province's sand paper are improved.
It polishes by the different of its object and openpore polishing can be divided into, putty is polished, priming paint is polished, finishing coat grinding and buffing is beaten
Mill etc..Openpore polish purpose be mainly decontamination, it is levelling, generally with the thicker sand paper of sand grains (such as 240#, 320#) along the grain side
To polishing, it is unable to plunge grinding or random disorderly mill, in order to avoid leave mixed and disorderly sand trace；Polish openpore when, it is necessary to pay attention to lines, stupefied
The protruding parts such as angle are unable to sand damage, deformation, to influence the smoothness and beauty of its lines, angle external form.Putty polishing requires to be flat
Whole, zero defect, the lines of the lines and openpore that grind want perfect harmony, therefore face the pads such as Shi Changyong wooden unit tool directly in polishing；Thoroughly
Putty polishing in bright coating is it is noted that completely by the putty polishing around crack, hole for nailing etc., be unable to mark.Priming paint polishing packet
The polishing of seal coat and the polishing of inter coat are included, the seal coat polishing before coloring mainly goes wolline wood to pierce, general to use
The sand paper of 320# -400#；In order to make uniform coloring, this time polishing requirement is light to be ground, uniformly, otherwise will cause coloring unevenly.Face
Paint polishing is required without bright star, without obvious sand trace, is most avoided finishing coat is worn out, is generally polished with 600# -1000# sand paper.Polishing grinding
Water mill generally is taken, first grinds off bright star with 800# -1000# sand paper, then with the light frosted trace of 1500# sand paper.
