Stir corrosion -free powder machine works .
Etching machine is based on the force of impact and heat tolerance design theory , is the result of physical processes and chemical reactions. Its role procedure is as follows ,
Additives in the etching machine mechanical stirring , emulsified , suspended in an aqueous solution of nitric acid , the etching has been spilled on the operating plate , the plate surface is etched to form a thin protective film complex . The adhesion of the protective film of different parts of the plate surface , due to the presence of the graphic portion of the photosensitive layer , the adhesion of the protective film is large.
No sensitive adhesive protective sheet metal parts , the direct impact of the solution by the etching machine , the impact of the protective film is opened nitric acid solution , a chemical reaction , the magnesium metal is etched by ion etching in a solution dissolved in the state of the machine , while the reaction heat. No corrosion site, relatively low temperature , so that the pattern edge is retained on the forming temperature is poor, the protective agent to enhance adsorption to prevent nitric acid corrosion. With continued agitation etching machine , metal plate corrosion deeper and deeper , the pattern formed along the sidewalls on the slope .

Etching machine basic structure can be divided into three parts , the host , control boxes and refrigeration systems.
Host structure :
Etching machine host by senior PVC casing is welded into a flat rectangular case , the top lid .
There turntable and jigs , fixtures corroded metal plate fixed on the cover ;
There is a separate motor plate etching machine , working it slowly rotates, driven plywood uniform rotation .
The cover off the front of the case , hinged links , one end of the support arm with heavy rail .
Several internal corrosion aligned parallel to the root of the spindle chassis , there are paddle shaft , several axes on the same horizontal plane , driven by a belt with the same angular velocity . Extends to both ends of the spindle chassis corrosion in vitro , and the pulley bearing are connected , then the lower boxes connected by a belt with FM motor.
Corrosion body chassis below the bottom position of the water line , a heating pipe, and the cooling temperature sensing meter pipes, cold water or a refrigerant circulating in the exhaust pipe , to reduce the temperature .
There bottom drain , the liquid can be discharged from here , for leveling and cleaning liquid when put to use acid .
Corrosion chassis frame body sitting on a square base, the base from the angle iron welded into the frame , bearing play , stabilizing role cabinet .
Fixed to the base powertrain , transmission shift system, cooling system water tanks , and other power , power components.
Cooling the end of the penetrating corrosion chassis wall , connected to an external air conditioner outdoor unit or cold water tank .

Control box structure :
Control box connected by cable to the etching machine host.
There are thermometers , tachometer, timer control table , start / stop button , auto / debug button , forced heating , cooling and other buttons on the control box .
There are a variety of corrosion inside the chassis electrical switches , transformer parts. And an external three-phase power .
Parameters of the machine running , real-time monitored by the instrument display , instrument parameters can be set to generate control commands.

 
Refrigeration system structure :
Copper , zinc plate etching machine generally use the air conditioning and refrigeration . Directly driven by the air conditioner outdoor unit refrigerant circulating in the exhaust pipe cooling cabinets , refrigeration .
Magnesium plate etching machine , due to the heat quickly, require more powerful cooling capacity , so the use of water-cooled indirect way .
Lower box , within the framework of the base, there is a cold water tank placed in the box with a condenser , driven by the air conditioner outdoor unit , water cooling ;
Corrosion of cold water from the pump into the body of the chassis cooling pipes, then back to the cold water tank , so the cycle to complete the cooling process .
 
 

Magnesium and zinc plate etching machine plate etching machine main differences:
Fast magnesium plate corrosion rate. For the preparation of the new medicine , general corrosion 3 minutes 80 wire (0.8mm). The heat generated by the chemical reaction in a short concentrated outbreak , so magnesium plate etching machine requires a strong ability to control the cooling temperature of the reaction . Magnesium plate etching machine requires one minute can cool down 5 degrees Celsius, zinc plate machine is generally one minute cool down 2 degrees Celsius.
Zinc plate machines use air conditioning , a direct cooling mode ; magnesium plate etching machine with cold water cooling , refrigerant belongs to indirect cooling ways. Magnesium plate etching machine equipped with a cold water tank , you can reserve cooling capacity in advance.
 
 
Cooling capacity can be accurately and timely control . This is perfectly etched magnesium plate , is essential.
Magnesium plate etching machine with exhaust system that can be discharged in time to produce nitric oxide gas temperature , the protection of fine lines .
Magnesium board machine at the maximum operating temperature 50 degrees Celsius, the number of revolutions at 600rpm.
To accurately control the layout of corrosion effects, sometimes need in a timely manner , manual manipulation etching machine , so the control box to have the debug file.

 
We have a full plate of magnesium corrosion process , for example, a brief description of the work etching machine .
Configured in accordance with the ratio of the first solution , to adjust the liquid level , and start corrosion , stirring for some time , the solution was mixed thoroughly , so that the emulsion additives , suspended in solution , and the solution was heated to the required temperature.
Setting the temperature control range etching machine , the blade speed , etching time .
The developer , open face , protecting over magnesium plate , placed on plywood , tighten ; close the lid , start the machine and start corrosion.
After reaching the set time , the machine automatically adjusts from high speed to low speed , and you should quickly open the cover , remove the zinc plates , cleaning , etching machine and then close the cover .
After the completion of the last magnesium plate corrosion , internal corrosion necessary and appropriate to add acids , additives, surface inspection , re-set temperature, speed , time, the adjustment is completed , and then start the next piece of magnesium plate corrosion.
Etching process, with the reaction plate and the magnesium nitrate increasing the heat released , the temperature was increased after reaching the upper limit set temperature , air starts , start cooling . Cooling the refrigerant in the discharge tube body chassis corrosion in circulation , remove heat, the temperature of the solution is reduced to complete the cooling process , until the temperature reaches the set value .
If the magnesium plate corrosion longer needed , layout corrosion more work etching machine cooling system may have to be repeated several times , the pump is running and stop controlled by the thermometer .

Technology Innovation major events :
1 so that corrosion control box and the host machine phase separation . The main benefit is to make the electrical components away from the mist , reduce corrosion and prolong the life of corrosion machines ; also for flexible placement , easy maintenance .
2 will be the first semi-enclosed refrigeration compressor refrigeration form to closed cooling system ( air-cooled systems homemade , equivalent to the current air conditioner outdoor unit ) ; further into hermetic refrigeration air conditioning system .
3 . Mechanical transmission etching machine by the first generation of mechanical outer -type continuously variable , instead of the second -generation of slip -type continuously variable transmission system , then upgrade to a belt -style , motor -type continuously variable transmission , until today's FM motor speed systems.
4 . The row of acid etching machine system transformation is automatic, manual combination .

The actual use of the process , can be set as magnesium plate etching machine uniform temperature control, time , operational procedures and other parameters for each corrosion process can also design special process control parameters such that the corrosion process of each piece magnesium board particularly can automatically , accurately , and procedures to be controlled .
