PTFE Spray

Fluoride resin electrostatic spray process is today world Shang most advanced of anti-corrosion process, first on equipment surface after high temperature except oil, and except rust, then on equipment surface for spray sand rough of, spray a layer special primer, and then will fluoride material powder through high pressure electrostatic equipment charging, and in farm of role Xia uniform of adsorption in was processing of equipment of surface Shang, then after high temperature baking, clinker particles on will melting into a layer dense of cover firmly attached in artifacts surface, for example 1mm thick of coated film, Also needs to be repeated 5-6 spray and baking, generally thick can be sprayed onto the 2mm fluorine materials PTFE, PFA, and FEP, ETFE, ECTFE, and PVDF several. Spraying lining equipment has been widely used in chemical industry, the pulp and paper industry, the food industry and the semiconductor industry.

1, lined reactor shell compatible with the steel welded atmospheric pressure vessel of JB/T4735-1997 or GB150-1998 of the steel pressure vessel norms.

2, various lining material: PTFE, and PFA and the FEP and the ETFE, ECTFE, and PVDF.

3, strong acid and alkali resistance, PH 1-14.

4, between the coating and the metal has very high binding capacity: force unable to remove metals and coating adhesion, as a man of the epidermis and the dermis.

It solves the traditional process of PTFE lining PTFE layer due to lack of adhesion with the metal base is easy to play drums. Off defects, more obvious in the context of frequent changes of temperature.

5, high purity and extremely low precipitation rate, meet the purity requirements of the photovoltaic industry.

6 broad, temperature, temperature-193~260?.

7, excellent stickiness-proof: after spraying not only has excellent anti performance at high temperature in use still has the unique anti-adhesive properties.

8, excellent resistance to vacuum: does not appear in any vacuum delamination (resistant to negative pressure -0.1Mpa).

9, excellent mechanical properties: high mechanical strength, high hardness and toughness.

PTFE sheet lining process description:

1, surface treatment of steel lining fluorine: sand blasting cleaning to Sa2, and detergents cleaning impurities, oil and so on.

2, with a coat of imported binders: binder used for industrial glue production company of the famous, this adhesive designed for bonding of PTFE sheet tailored and can withstand 180 ?. Corrosion resistance and ease of processing.

3, sheet paste: paste the good adhesive coated sheets in the shell lining surface, strength >10N/mm paste.

4, plate weld: pasted good plate to weld, after welding and post weld, weld strength reached the strength of sheet 95%, spark test voltage 20KV breakdown.

5, nozzle configuration: a prefabricated pipe into the pipe lining and lined with the device parts welding, weld strength reached the strength of sheet 95%, spark test voltage 20KV breakdown.
