Abstract
The present invention provides an electrostatic plastics-spraying method for garbage can. Said invented method includes the following steps: pretreating can body, spray-coating and solidifying so as to form a compact coating layer with uniform colour and strong adhesive force on the surface of can body to make garbage can possess good acid-proof alkali-resisting and heat-resisting property.
Description
The present invention relates to the electrostatic plastic spraying field, particularly be applicable to the electrostatic plastic spraying process of dustbin.
Normally used dustbin surface is all adopted varnished; Varnished not acid and alkali-resistance, weatherability is poor, perishable getting rusty, life cycle is short; It is attractive in appearance also to have a strong impact on the appearance of the city.
The object of the present invention is to provide a kind of electrostatic plastic spraying process that is used for dustbin, adopt this method can form on staving surface fine and close, color and luster evenly, the coating of strong adhesion, make dustbin have acid-alkali-corrosive-resisting and hear resistance preferably.
Purpose of the present invention is achieved by following steps:
(1) staving is put in people's degreasing pond after the degreasing, put the washing of people's clear water reserviors;
(2) staving is put rust cleaning, washing again in people's acid pond;
(3) put neutralization in people's neutralization pond, washing again;
(4) putting the people shows to transfer and carries out the surface in the pond and adjust;
(5) put processing in people's phosphatization pond, clean the back air dry;
(6) staving is used the purification of compressed air dedusting;
(7) move people's powder spraying chamber, carry out the high-pressure electrostatic plastic-blasting,
(8) the staving face coat is cured.
When the staving face coat was cured, operating temperature was 170-190 ℃, and be 20 minutes hardening time.
The coating that adopts electrostatic plastic spraying process to produce on the dustbin surface have densification, color and luster evenly, characteristics such as good, the good decorating effect of strong adhesion, physical and mechanical properties, long service life.
Further specify the present invention below in conjunction with production technology.
At first dustbin is carried out preliminary treatment, put into the degreasing of degreasing pond, after 15 minutes, sling and put the washing of people's clear water reserviors, put in people's acid pond rust cleaning then 20 minutes, wash again with the frock staving of slinging; Put in people's neutralization pond again and neutralize, put the people after the cleaning and show to transfer and carry out surface adjustment in the pond, put at last people's phosphatization pond in 20 minutes, clean air dry afterwards, the staving surface has just formed the grey phosphating coat; Carry out high pressure electrostatic painting then, the rubbish staving is fixed on the frock, use the purification of compressed air dust removal, move people's powder spraying chamber, staving sprays by order from the inside to the outside, spray gun is to the about 150～250mm of surface of the work distance, and from the powder belt negative electrical charge of spray gun ejection, powder flies to the dustbin of positively charged and is adsorbed on the staving; At last simplified surface is cured processing, curing is important procedure in the spraying operating process, and the length of hardening time is extremely important, too short incomplete film forming, poor performance, the especially bad mechanical property of solidifying of time; Time is oversize, may produce heat ageing, the generation aberration of filming.Be 20 minutes hardening time among the present invention, solidification temperature 170-190 ℃.Dustbin solidifies the back and takes out from baking oven, adopts the nature type of cooling, makes workpiece temperature reduce to room temperature.
Claims (2)
1. electrostatic plastic spraying process that is used for dustbin is characterized in that may further comprise the steps:
(1) staving is put in people's degreasing pond after the degreasing, put the washing of people's clear water reserviors;
(2) staving is put rust cleaning, washing again in people's acid pond;
(3) put neutralization in people's neutralization pond, washing again;
(4) putting the people shows to transfer and carries out the surface in the pond and adjust;
(5) put processing in people's phosphatization pond, clean the back air dry;
(6) staving is used the purification of compressed air dedusting;
(7) move people's powder spraying chamber, carry out the high-pressure electrostatic plastic-blasting;
(8) the staving face coat is cured.
2. the electrostatic plastic spraying process that is used for dustbin according to claim 1 is characterized in that in the curing process, and operating temperature is 170-190 ℃, and be 20 minutes hardening time.
