Abstract
The invention relates to the technical field of spraying processes, in particular to a low-friction spraying process for an escalator skirt board, which adopts the whole process flow that: after being degreased, derusted, acid-washed, phosphated, washed, dried and the like, a workpiece satisfies the spraying requirements; and then the workpiece is sprayed with low-friction powder and is solidified after spraying, so that a coating layer with low friction coefficient is formed on the surface of the workpiece. Therefore, the escalator skirt board satisfies the corresponding requirements in the EN115-2008 standards.
Description
Technical field:
The present invention relates to the spraying coating process technical field, relate in particular to the low friction of staircase skirtboard spraying coating process.
Background technology:
Staircase is a kind of circular flow step that has; The fixedly driven by power equipment of conveying people is used for tilting up or down; Its structure is mainly by step, step driving unit, driving host, drive disk assembly, nervous device, armrest system, metal structure, step roller track, cover plate, fishback, safety device and the electrical part parts that grade are formed up and down; Has continuous operation; The characteristics that freight volume is big are widely used in the vertical transport of the public places such as subway, light rail, station, airport, harbour, shop and mansion that the stream of people concentrates.
In staircase EN115-2008 standard-required 5.5.3.4 bar; Require escalator should reduce the possibility that stagnates and hinder between its step and the apron plate; D wherein) point requires below apron clamp preventer, to use suitable material or suitable lining face, and purpose makes the coefficient of friction of itself and leather, PVC and rubber less than 0.45.In the existing staircase skirtboard production technology, be difficult to accomplish the requirement of above standard.
Summary of the invention:
The objective of the invention is to be directed against the deficiency of prior art and provide a kind of staircase skirtboard the low spraying coating process that rubs, make the staircase skirtboard satisfy the corresponding requirements of staircase EN115-2008 standard.
For realizing above-mentioned purpose, the present invention adopts following technical scheme:
The low friction of staircase skirtboard spraying coating process, it may further comprise the steps:
Step 1, degreasing: earlier standard workpiece working index value is arrived in the parameter adjustment of the degreasing working solution in the degreasing bath; Then workpiece is hung in the degreasing bath, guarantee that the degreasing working solution did not have workpiece 10cm; Reach the regulation degreasing time, take out workpiece in the degreasing bath and put into rinsing bowl and clean the back and observe moisture film and change, occur, then get into step 2 like moisture film crack-free situation after 30 seconds;
Step 2, washing: open the recirculated water tap, in rinsing bowl one, put into workpiece and dynamically clean, scavenging period is no less than 60 seconds, gets into step 3;
Step 3, whether rust cleaning or pickling: observing workpiece has rust, has rust then to change rust cleaning in the rust cleaning groove over to, and the rust cleaning back gets into step 4; Rustlessly then carry out pickling, get into step 4 after the pickling;
Step 4, washing: open the recirculated water tap, in rinsing bowl two, put into workpiece and dynamically clean, scavenging period is no less than 60 seconds, gets into step 5;
Step 5, neutralization: in the neutralization chamber, arrive standard workpiece working index value earlier with the parameter adjustment of working solution; Put into workpiece and dynamically clean, the time is no less than 60 seconds, gets into step 6;
Step 6, table is transferred: the parameter adjustment that will show to transfer the table accent working solution in the groove earlier is to standard workpiece working index value; Put into workpiece and dynamically clean, the time is no less than 60 seconds, gets into step 7;
Step 7, phosphatization: earlier standard workpiece working index value is arrived in the parameter adjustment of the phosphatization working solution in the phosphatization groove; Put into workpiece and dynamically clean, the time is no less than 15-20 minute, gets into step 8;
Step 8, washing: open the recirculated water tap, in rinsing bowl three, put into workpiece and dynamically clean, scavenging period is no less than 60 seconds, gets into step 9;
Step 9, washing: open the recirculated water tap, in rinsing bowl four, put into workpiece and dynamically clean, scavenging period is no less than 60 seconds, gets into step 10;
Step 10, oven dry: in 100 ℃ of-140 ℃ of temperature environments, workpiece is dried, drying time is 10-20 minute, gets into step 11;
Step 11, dedusting: with the antistatic rag workpiece is carried out wiping earlier; Carry out dedusting with hairbrush then; With compressed air surface of the work is cleaned again; Get into step 12;
Step 12, inspection before the spraying: whether the inspection workpiece meets the spraying standard, gets into step 13;
Step 13, spraying: if the workpiece material is a galvanized sheet, then use the trade mark to dust as dusting coating as the low friction black of I53690052250, coating thickness is 2mm; If the workpiece material is the hairline stainless steel, then use the trade mark to dust as dusting coating as the low friction of I536-0053 2200 is transparent, coating thickness is 1.5mm; The spraying back gets into step 14;
Step 14, inspection before solidifying: inspection Workpiece painting situation gets into step 15;
Step 15 is solidified: preset the solidification temperature and the constant temperature time of curing oven, workpiece is placed in the curing oven solidify; Solidify the back that finishes and get into step 10 six;
Step 10 six, product examination: comprise the observation workpieces surface condition, detect coating layer thickness, detect coating hardness, detect coating adhesion; Get into step 10 seven;
Step 10 seven, packing: the spraying workpiece must be isolated product with the pearl cotton behind the first pasting protective film again, packs then or cases;
Above-mentioned workpiece is the staircase skirtboard.
For preventing to go here and there liquid, said step 1 is to step 9, and each step needs the first drop workpiece liquid next step of being allowed for access to the greatest extent.
Said step 12, inspection before the said spraying, for inspection workpiece phosphating coat whether careful, closely knit and complete, and whether non-secondary pollution and no rusty stain.
Inspection before the said step 14, said curing, whether evenly smooth for inspection Workpiece painting face, whether do not have the spray of leakage, tong mark and people and be the grazing vestige.
Beneficial effect of the present invention is:
The low friction of staircase skirtboard of the present invention spraying coating process; After its whole process flow has carried out comprising that to workpiece degreasing, rust cleaning, pickling, phosphatization, washing, oven dry etc. are handled; Make workpiece satisfy the spraying requirement, to the low friction powder-spraying of Workpiece painting, carried out cured after the spraying again; Make surface of the work be formed with the coating of low-friction coefficient, make the staircase skirtboard satisfy the corresponding requirements of staircase EN115-2008 standard.
