Analysis of the shortcomings of traditional methods for cleaning jewelry with heated acid
1. Messy scene: wire unprotected, beakers or casserole explosive, electric furnace uncovered, electric furnace can be corroded by strong acid, cause short circuit, electric leakage and other dangerous situations.
2. Thick smoke: There will be thick acid mist in the instant of acid burning and color hanging. The effect of traditional method is poor; besides, devastating effect can be generated on electric appliances and personnel in operating room.
3. High risk: There are high risks of electric etching, etching wire, beaker burst, concentrated acid splash, short circuit of electric appliance, choking smoke, etc. Accidents are not rare.
Specification Parameter Table of the machine for cleaninging jewelry with heated acid:
| Model | XHF-2S | XHF-3S |
| Designed air volume(m³/h) | 300 | 400 |
| Dimensions of acid burning cabinet L*W*H(m) | 1.5*0.76*1.83 | 2.0*0.76*1.83 |
| Material | Imported PP + titanium plate + imported quartz glass | Imported PP + titanium plate + imported quartz glass |
Advantages of this machine for cleaninging jewelry with acid:
1. Complete configuration: a set of machine = jewelry cleaning table-board (titanium) + electric furnace (2-3 sets optional) + 2-3 customized beaker (Germany quartz, temperature difference resistance) + 2-3 quartz artifact baskets + ventilation hood exhaust pipe + wash tank + sedimentation tank + emergency liquid storage tank + electrical control system. The overall size is only 2000 * 760 * 1830MM;
2. Easy to operate: It is equipped with electronic control system, and operated by button; artifact baskets are used for goods picking and claiming. Baskets have handles, easy to operate.
3. High safety:
A; special customized beakers and electric furnace: German quartz beakers produced with 1200 ºC high temperature annealing, with strong resistance to temperature difference, the service life is usually about 6-12 months; infrared electric furnace comes with temperature control, all wires are hidden to completely isolate from the highly corrosive environment;
B: PVC door curtain: PVC door curtain is set up to protect the safety of personnel. It can facilitate the observation, and also prevent the concentrated acid splash.
C: Emergency pipeline system: Emergency acid-leading pipeline is set up, for strong acid to import into contingency collection tank of high-temperature and strong acid resistance along with PP pipeline in case beaker bursts. In this way, the acid liquor will not splash out, equipment will not be damaged and personal will not be hurt.
4. Thick smoke management:
Automatic interchange suction hood is equipped to realize lateral, upper and top air draft. Wind path can be automatically selected for materials picking up or fried acid. In this way, there is no need to worry about smoke affecting environment and personnel safety;
5. Easy mobility:
the machine comes with portable casters, which are convenient for equipment installation and use.
