Description
Technical field
The utility model is related to component overlay coating field of weaving, more particularly to a kind of special chromium plating pin cloth of spinning.
Background technology
Existing pin cloth due to its special pin cloth structure causes that its surface can not be protected by conventional mechanical processing
The smoothness on surface is demonstrate,proved, therefore in textile process operation, be easy to cause yarn breakage and comes off, cause low production efficiency, life
It produces of high cost.
Utility model content
The technical problem to be solved by the utility model is to provide a kind of special chromium plating pin cloth of spinning, and pin cloth surface is carried out
Chromium plating provides the service life of pin cloth, and crown structure is improved, and prevents spinning from coming off and being broken, to solve to lead in the prior art
The above-mentioned defects of cause.
To achieve the above object, the utility model provides following technical solution：A kind of special chromium plating pin cloth of spinning, including
Pedestal and crown, crown are arranged on the upper surface of pedestal, spaced set, the plating hard chromium on surface layer of the pin cloth.
Preferably, the crown is formed by pedestal cutting rim charge.
Preferably, the cut surface of the crown includes segmental arc, straightway and oblique line section, adjacent oblique line section and segmental arc
Form crown.
It is using the advantageous effect of above technical scheme：The utility model pin cloth, cutting rim charge forms, simple for process, and
And the structure of crown is improved, it avoids spinning and comes off from crown, the fracture that crown causes spinning is also prevented from, with hour hands cloth
Chromium plating, avoid at a high speed by spinning pin cloth is caused to wear, the service life of pin cloth is provided.
Description of the drawings
Fig. 1 is the structure diagram of pin cloth.
1-- pedestals, 2-- crowns, 3-- segmental arcs, 4-- straightways, 5-- oblique line sections
Specific embodiment
The following detailed description of the preferred embodiment of the utility model.
As shown in Figure 1, a kind of special chromium plating pin cloth of spinning, including pedestal 1 and crown 2, crown 2 is arranged on the upper of pedestal 1
Surface, spaced set, the plating hard chromium on surface layer of the pin cloth.
Crown 2 is formed by pedestal cutting rim charge, and the cut surface of crown 2 includes segmental arc 3, straightway 4 and oblique line section 5, phase
Adjacent oblique line section 5 and segmental arc 3 form crown.
The utility model pin cloth, cutting rim charge forms, simple for process, and the structure of crown is improved, and avoids
Spinning comes off from crown, is also prevented from the fracture that crown causes spinning, with hour hands cloth chromium plating, avoid at a high speed by spinning to pin cloth
It causes to wear, the service life of pin cloth is provided
A kind of continuous chrome-plated process of pin cloth, it is right using chemical plating using unwinding system driving pin cloth successively by technology groove
Pin cloth surface carries out chromium plating, which includes,
1) it is surface-treated, oil removal treatment is carried out to pin cloth surface；Including electrochemical deoiling and electrochemical degreasing.
Electrochemical deoiling uses alkaline degreaser, and oil removing agent concentration is 50g/L, and temperature is 70 DEG C, time 30min.
Electrochemical degreasing uses alkaline degreaser, and degreaser cathode concentration is 30g/L, and degreaser cathode concentration is 50g/L,
Temperature is 70 DEG C, time 180sec, current density 10ASD, and electrode uses stainless steel or graphite.
2) polish, chemical polishing is carried out to pin cloth surface；In polishing step, carried out using the mode of impregnated ground agent
Electrochemical deoiling, at 17 DEG C, pH value 2.0, time 3min stings erosion 2 μm/minute of rate for temperature control.
3) activate, volume ratio is used to carry out activation process, time to pin cloth surface for 30% hydrochloric acid：5min；
4) chromium plating, in pin cloth chrome-faced, using chemical plating to pin cloth plating hard chromium on surface；
5) dry.
Adverse current washing is carried out between surface treatment and polishing；Adverse current washing is carried out between activation and chromium plating；Chromium plating and drying
Between carry out adverse current washing, wherein, chromium plating and drying between using pure water carry out adverse current washing.
Electrochemical deoiling agent is multi-functional using one kind, not the non-foam powder degreaser of phosphate-containing and silicate, can
Effective removal stainless steel, zinc, nickel, a variety of lubricants and grease of copper and its alloy surface.
In adding procedure, definite, point following several steps of the additive amount to adding degreaser,
1) tank liquor of 10ml is drawn, is placed in beaker, adds in 100mlDI water；
2) 4-6 drop phenolphthalein indicators are added in；
3) titrated with the hydrochloric acid standard solution of 1.0N by red to colourless as terminal；
4) additive amount of degreaser is the additive amount of 7 times of hydrochloric acid standard solution.
Electrolytic degreasing agent one kind is multi-functional, not the non-foam powder degreaser of phosphate-containing and silicate, can effectively go
Except stainless steel, zinc, nickel, a variety of lubricants and grease of copper and its alloy surface.
In adding procedure, definite, point following several steps of the additive amount to adding electrolytic degreasing agent,
1) tank liquor of 10ml is drawn, is placed in beaker, adds in 100mlDI water；
2) 4-6 drop phenolphthalein indicators are added in；
3) titrated with the hydrochloric acid standard solution of 1.0N by red to colourless as terminal；
4) additive amount of degreaser is the additive amount of 8.28 times of hydrochloric acid standard solution.
Mode that there are two types of the grinding preparation of reagents modes,
A kind of water for first injecting 1/3 volume groove body, the grinding reagent of addition 8-12% (v/v)；
Another is the water for first injecting 1/3 volume groove body, the grinding reagent and 25% (v/ of addition 12-13.5% (v/v)
V) hydrogen peroxide.
Specific step is washing, and -- using the hydrochloric acid activation of 30-40% (v/v), -- washing -- polishing -- washing, is polishing
It is preceding thoroughly to clean and remove surface oxide layer by activating.
The continuous chrome-plated process of the utility model pin cloth is formed using the technology groove of unwinding equipment and corresponding each processing step
Special chrome plating equipment carry out chromium plating, realize pin cloth continuous plating, theoretically the chromium plating length of pin cloth can reach endless, greatly
The big efficiency for improving pin cloth chromium plating, realizes automation mechanized operation, reduces production cost.
Using chemical polishing before chromium plating, the quality of chromium plating after raising, while using chemical plating come hard chrome plating, guarantee
Coating on pin cloth is uniform.
Existing similar-type products on the market, black pin cloth (to be only surface polishing by handling) unit price 200/m members；
White pin cloth (passing through simple process) 400 yuan/m of unit price；High standard pin cloth unit price 800-900 members/m are made of the application technique
Pin cloth, high standard pin cloth is equal in quality, and theoretic processing cost is 200 yuan/endless.
The cost price of product is greatly reduced, generates great economic benefit.
Above-described is only the preferred embodiment of the utility model, it is noted that for the ordinary skill of this field
For personnel, on the premise of not departing from the utility model and creating design, various modifications and improvements can be made, these all belong to
In the scope of protection of the utility model.
