What is the difference between the different filter materials of the electroplating filter?

There are four factors for the selection of electroplating filters:

1) Select the pump or filter material according to the composition, concentration and temperature of the liquid medicine.

PVDF applicable conditions: temperature can withstand up to 95 degrees, strong acid resistance (hydrogen peroxide, hydrofluoric acid, aqua regia, bone water, etc.) FRPP applicable conditions: temperature can withstand up to 70 degrees, resistance to general acid and alkali (a few are not resistant, such as hexavalent chromic acid, but PVC can be used).

2) According to customer requirements, select the appropriate type of pump or filter for applicable occasions.

Filter: electroplating filter, activated carbon treatment machine for waste acid treatment, electroless nickel filter for electroless nickel plating, chromic acid filter for hard chrome plating. Pump:

magnetic pumps (electrophoretic paint, pearl nickel plating, small filters - few bubbles); Vertical pumps (electrophoretic coating, exhaust gas treatment, electroless nickel filters – can be used for liquids containing crystalline particles, resistant to idling); Self-priming pump (electroplating liquid conveying, wastewater treatment - strong self-priming, universal pump, low cost).

3) The influence of plating on the selection.

a, galvanized and copper plating with acid and alkali plating, acid plating with filter element filter bag general accuracy of 1-5U; Alkalinity copper can be used 5u; Alkali galvanizing generally uses 10-20u filter element filter bags. Chemical liquid filter (electroplating filter).

b.Nickel plating: electroplating is generally more than 50 degrees, there is water mist plating, pearl plating is also called satin plating (bubble requirements are strict, magnetic pump is used), and a general filter can be used. Electroless plating, special nickel plating filter (vertical pump), high temperature PVDF material pump, low temperature FRPP material.

c.Chromium plating: there are trivalent chromium and hexavalent chromium (hard chromium), due to the different acidic influences, trivalent (frpp pump) ordinary electroplating filter on the line, hexavalent (pvdf pump) chromic acid filter (filter cartridge pvc).

4) Select the pump according to the head and flow requirements; According to the size of the cylinder groove, the number of cycles selects the filter (filtration volume = cylinder tank capacity * number of cycles hours).

For example: the length of the tank is 1m, the width is high, the number of cycles is 5-8 times, and the number of cycles of alkalinity is relatively large.

Answer: 1*, so choose 10 tons of electroplating filtration.

The different materials of the plating filter determine the weather resistance of the filter.

The materials commonly used in electroplating are PP and PVDF (polymer) filters.

This type of filter can withstand temperatures below 95 degrees Celsius, can resist acid and alkali, and is widely used in the electroplating industry.

The electroplating filter has the following functions:

1. Circulating filtration, there may be dust in the electroplating solution, there will also be burrs falling on the hanger, and the anode may also produce anode mud, these impurities may float to the parts to be plated to form defects, therefore, in the electroplating production, the installation of a filter circulating filter tank liquid, can reduce the generation of such defective products, generally required to filter 4 6 times per hour;

2. When the bath is filtered, the bath is used for a certain time or some other bath defects, and the electroplating additives and other impurities in the bath need to be removed, and the treatment step is to add hydrogen peroxide.

or potassium permanganate.

Heating – plus activated charcoal.

Adsorption - filtration, at this time, the filter is mainly to filter out activated carbon and other solid impurities;

3. The filter can also be used as an acid and alkali resistant water pump.

The purpose of the filter: It is mainly used for the separation of solids and liquids. Compared with other solid-liquid separation equipment, the liquid filtered by the filter has a higher solid content and excellent separation effect.

The basic principle of solid-liquid separation is that the mixed liquid flows through the filter cotton core (filter cloth), and the solids stay on the filter element and gradually accumulate on the filter element. The filtrate part penetrates the filter cloth and becomes a clear liquid that does not contain solids.

The filter is a commonly used filtration and separation equipment in electroplating, chemical, liquid medicine and other industries, which was used in chemical production at the beginning of the 18th century, and is still widely used in hardware electroplating, plastic electroplating, circuit board (PCB), electronics, wastewater treatment, environmental protection waste gas treatment, etching cleaning, anodizing, electrophoretic coating production and other industries. The filter is composed of multiple filter elements and filter barrels to form a filter chamber, and the pressure is the filter driving force. Filters are mainly divided into:

PP filter, PVC filter, filter cartridge copper plating filter, filter bag nickel plating filter, Yangtao gold plating filter, filter paper galvanized filter, filter cloth chrome plating filter, electroless nickel filter and other different styles of filters.

The purpose of the filter: it is mainly used for solid-liquid separation. The liquid medicine is filtered by pressure, and is widely used in metal plating, plastic electroplating, circuit board (PCB), electronics, wastewater treatment, environmental protection waste gas treatment, etching cleaning, anodizing, electrophoretic coating production and other industries.

Especially for the separation of viscosity, it has its unique advantages.

How the filter works.

The working principle of the filter: the filter liquid is sent into the filter chamber under strong pressure, and the solid part of the filter liquid that enters the filter chamber is intercepted on the filter element by the filter cotton core (filter cloth), and the liquid part is discharged from the filter chamber through the filter cotton core, so as to achieve the purpose of solid-liquid separation.

In terms of style, the filter is divided into pressing plate type and lock cap type; In terms of filtration levels, there are single barrels and double barrels; In terms of filter plate materials, there are PVC, FRPP, PVDF, SUS304 316; But no matter what kind of filter, its working principle is first of all pressure filtration, the filter element and the filter barrel form a filter chamber, the filter liquid is sent into the filter chamber under strong pressure, the solid part of the filter liquid that enters the filter chamber is intercepted on the filter element by the filter cotton core (filter cloth), and the liquid part is discharged from the filter chamber through the filter cotton core (filter cloth), so as to achieve the purpose of solid-liquid separation, with the increase of pressure, the solid-liquid separation is more thorough, but from the energy and cost considerations, too high pressure is not cost-effective.

Filtration mechanism: The filtration mechanism is composed of a filter barrel, a filter element, a tripod, an acid and alkali resistant self-priming pump, and the filter barrel is composed of a buckle, a monocular screw, a handle, a pressure gauge, etc. The tripod consists of a bucket and a rack; The acid-base resistant self-priming pump consists of a motor and a pump head.

The liquid medicine enters the filter barrel from the acid and alkali resistant self-priming pump.

Solid particles are trapped in the filter element because their particle size is larger than the pore size of the filter medium (filter cloth).

The liquid flows out of the outlet of the filter barrel.

The filter on the electroplating has the following uses: 1. Circulating filtration, there may be dust in the electroplating solution, and there will be burrs falling on the hanger, and the anode may also produce anode mud, and these impurities may float to the parts to be plated to form defects, therefore, in the electroplating production, the installation of the filter circulating filter tank liquid can reduce the generation of such defective products, and it is generally required to filter 4 6 times per hour; 2. When the bath is filtered, the bath is used for a certain time or some other tank defects, and the electroplating additives and other impurities in the bath need to be removed, and the treatment step is to add hydrogen peroxide (or potassium permanganate) - heating - plus activated carbon adsorption - filtration, at this time the filter is mainly to filter out activated carbon and other solid impurities; 3. You can also use the filter as an acid and alkali resistant water pump.

The electroplating filter is a device that uses vacuum as the filtration power to separate the solid-liquid slurry. It is an excellent filtration equipment for iron ore concentrate, non-ferrous metal concentrate and non-metallic concentrate filtration operations.

The reason why the plate and frame filter press can flourish and be widely used in various industries is that its biggest advantage is positive pressure and high pressure pressure dehydration, which is much larger than the pressure difference of the traditional vacuum filter, so the filter cake has low moisture, less energy consumption, less metal loss, and the filtrate is clear and transparent. As early as more than ten years ago, some experts pointed out that the filter press is the only excellent equipment among all industrial filters that can ensure that the moisture content of the filter cake reaches less than 10% and can be without flocculants. There are many models of filter presses, and filter presses are divided into, box type, plate and frame type, and bag type.

1. An important basis for purchasing corrosion-resistant filters.

1. Select the material of the electroplating filter by the composition, temperature and nature of the liquid conveyed. PVDF material can generally withstand high temperature of 95 degrees, strong acid and solanine. FRPP material can withstand 70 degrees, and is suitable for general acid and alkaline liquids.

2. Users can choose the appropriate corrosion-resistant filter type and pump according to their own needs.

The filter is generally divided into electroplating filter, electroless nickel filter for electroless nickel plating, activated carbon treatment machine for waste acid treatment, and chromic acid filter for hard chrome plating. Acid and alkali resistant magnetic pumps are generally used in electrophoretic coating, small and medium-sized electroplating filters, etc. Vertical pumps are generally suitable for exhaust gas treatment, electrophoresis process, and electroless nickel filters can be used for liquids containing crystalline particles, which can be idled.

3. Through the pump head, the flow demand is selected by the pump. Through the size of the cylinder tank, the number of cycles selects the filter (filtration volume = cylinder capacity * number of cycles h).

Second, the advantages of corrosion-resistant filters.

1. The corrosion-resistant filter has the advantages of high filtration, wide filtration area, simple operation, high efficiency and easy cleaning.

2. The main barrel of the corrosion-resistant filter is made of PP material integrated injection molding, which has the characteristics of strong and durable, no leakage, acid and alkali resistance and high temperature resistance.

3. The filter material of the corrosion-resistant filter is designed vertically, and other components are easy to replace, and the user can replace them at any time according to the customer's requirements.

The electroplating filter is a variety of electroplating liquid circulating filtration, PLC microcomputer automatic control.

In the process of electroplating, it is often encountered that the process and operation control are under normal conditions, but the electroplating products are not satisfactory. Defective products such as burrs and pittings often occur, and the medium and wide sludge generated by Anode Yongjie, the incomplete pretreatment of product electroplating, the dirt brought in by the product and the precipitation generated by chemical reactions all have a considerable impact on the point pair. For example, in the process of nickel plating reaction, nickel particles will inevitably be generated, which must be removed in time, not to mention that the transfer liquid will be used continuously for a period of time and will produce other impurities, such as not filtering in time will seriously affect the service life of the transfer liquid and stabilize the pants cultivation designation, so that the coating is rough.

The installation of a filter to circulate the filter bath fluid can reduce the generation of such defective products.

Advantages: 1. The corrosion-resistant filter has the advantages of high filtration, wide filtration area, simple operation, high efficiency and easy cleaning.

2. The main barrel of the corrosion-resistant filter is made of PP material integrated injection molding, which has the characteristics of strong and durable, no leakage, acid and alkali resistance and high temperature resistance.

3. The filter material assembly design of the corrosion-resistant over-hu filter machine is easy to replace other components, and the user can replace it at any time according to the customer's requirements.

The electroplating filter adopts a filter bag filter material design, and the liquid medicine is filtered through the filter bag, and it is easy to disassemble and clean. The main body and all important parts are integrally molded with PP material, which has high temperature resistance, acid and alkali resistance and other special excavation properties.

1. Determine the type of filter according to the chemical properties of the chemical agent Sakura liquid to be electroplated and filtered. For such as copper, nickel, zinc plating, etc., you can choose a conventional electric spine Nianzi plating filter; For strong acids such as hexavalent chromic acid plating, it is necessary to choose a special filter for chromic acid.

2. Determine the size of the filter according to the filtration volume of the solution. If the amount of liquid to be filtered is 10t, a 10t filter should be used.
