Abstract
The invention relates to a detergent for sprayed glass bead dust on aluminum alloy and a dedusting method thereof. According to the dedusting method, an aluminum alloy piece which is sprayed with glass beads is put into a detergent composed of ammonium bifluoride (NH4HF2) with a concentration of 160 to 200 g/l, nitric acid HNO2 with a concentration of 20 to 30 ml/l and a small amount of an additive, with the temperature of the detergent being 10 to 40 DEG C and deterging time being 10 to 60 s; then, the aluminum alloy piece is rinsed with flowing water, and glass bead dust is completely deterged; subsequently, the aluminum alloy piece is subjected to surface treatment like chemical polishing, stain removing, deoiling, anodic oxidization, black dyeing, sealing treatment, rinsing with flowing hot pure water, drying, etc. The method provided in the invention has a very good dedusting effect and enables aluminum oxidation quality of the aluminum alloy piece to be substantially improved and an obtained product to be cleaner and more beautiful.
Description
Technical field
The present invention relates to a kind of industrial dust removal method, especially a kind of duraluminum spray granulated glass sphere dust clean-out system and dust removal method thereof.
Background technology
Phoenix optics will use a large amount of aluminum alloy parts in the manufacturing processed of carrying out optical precision instrument; Mainly be through precision work surfaces of aluminum anodic oxidation again; In recent years along with the development in market; Ornamental satin face aluminium alloy anode oxide is more and more, develops into the various satin face anodic oxidation of series from the anodic oxidation of original single metal spraying emery satin face; The shaping of satin face is also handled by original spray 100# silicon carbide, develops into present spray 150#, 220# granulated glass sphere and shot etc., and the oxidation of spray granulated glass sphere satin face is main ornamental oxidation, its epigranular, and exquisiteness, decorative effect is good.So general appearance spare, mostly number is to handle through the spray granulated glass sphere, plays ornamental requirement, but the spray granulated glass sphere can produce a large amount of glass dust; These glass dust through the injection of spray granulated glass sphere, are beaten on the aluminum alloy part surface, and duraluminum is had a kind of avidity; This layer glass dust (or glass ash) does not all come out in part optical polishing, alumilite process and each road cleaning process so that make the part aluminaization also have one deck white dust behind the black, thereby have a strong impact on black ornamental of satin face anodic oxidation; Before not having the present invention, be to lean on by hand to wipe one by one, smear or scrub clean, not only efficient is very low; Cost is very high, and quality can't guarantee that the present invention is the method through chemistry; Search out a kind of chemical substance or prescription, in liquid medicine, soak the part that sprayed granulated glass sphere the several seconds, make glass dust and liquid medicine reaction on the part; Till the removal of glass dust, carry out normal chemical rightenning alumina black again, through increasing the dedust operation; Just do not had the white glass dust after the part aluminaization is black, and this prescription liquid medicine does not injure part yet, can go ash totally again.This dust removal method, stable operation is reliable, and dedust is effective, and efficient is high, has improved the quality of aluminaization.
Summary of the invention
It is reliable to the purpose of this invention is to provide a kind of stable operation, and dust removal is effective, and efficient is high, improves the duraluminum spray granulated glass sphere dust clean-out system and the dust removal method thereof of alumina quality.
The present invention solves through following technical proposal:
Clean-out system composition of the present invention is formed and concentration content proportioning is:
Matt salt (NH
4HF
2) 160～200g/l
Nitric acid HNO
320～30ml/l
Additive is a small amount of.
Dust removal method of the present invention is that the Al-alloy parts that sprayed granulated glass sphere is immersed in the clean-out system of above-mentioned composition composition and concentration content proportioning thereof; Making the clean-out system temperature is 10～40 ℃; Scavenging period is 10～60s; Later use flowing water cleaning aluminum alloy spare, the granulated glass sphere dust promptly cleans up, carries out chemical rightenning again, goes stain, electrochemical deoiling, anodic oxidation, dyes the surface treatments such as hot pure water cleaning, drying of handling, flow of black, sealing of hole.
The Al-alloy parts that sprayed granulated glass sphere carries out other surface treatment again after past dust operation, can improve alumina quality, the product precision of Al-alloy parts greatly, makes product clean more attractive in appearance.
At present, because this method dust removing effects is very good, the present invention has weaved into phoenix enterprise process of surface treatment, is applied in batches produce.
