Product Details

_High temperature organic silicon sprayingDust removal frameworkPre treatment and spraying process of bag cage bone with organic silicon

1. Organic silicon pretreatment process: degreasing - water washing - acid washing - water washing (purpose: to remove surface oil stains and rust spots) surface adjustment - phosphating - water washing - surface adjustment (purpose: to enhance the adhesion of bag cage surface coating).
2Organic silicon bag cage,Dust removal frameworkOrganic silicon spraying process: dehydration - surface spraying of organic silicon powder (coating thickness: 100-150 μ m) - high temperature curing (baking at a high temperature of 220 ℃ for 120 minutes. After preservation at 200 ℃, heat setting for 30 minutes) - natural cooling of the bag cage.

The size of the 5 organic silicon bag cage and dust removal skeleton meets the requirement of tight fit with the filter bag, which plays a role in supporting the filter bag and maintaining its shape under tension during filtration and dust cleaning.
The 6-bag cage requires the anti support ring and longitudinal reinforcement to be evenly distributed, and should have sufficient strength and rigidity to withstand the gas pressure of the filter bag during filtration and dust cleaning. After running under negative pressure of 5000Pa for 1 hour, the plastic deformation should be less than 3mm, and there should be no detachment of the welding points.
The 7-bag cage can prevent damage and deformation caused by collisions and impacts during normal transportation and installation.
The axial verticality deviation of the 8 organic silicon bag cages and dust removal skeleton is ≤ 10mm, and the concentricity deviation of the two bag cages is less than 1mm. The allowable deviation of the bag cage length is negative deviation of -3~-6mm.
All welding points of the 9-bag cage should be firmly welded, and there should be no loose welding, virtual welding, or missed welding.
When making the 10 bag cage support ring, the joint should be neat, and after the joint is completed, the joint should be polished to ensure a smooth and polished surface.
The surface of the 11 bag cage in contact with the filter bag should be smooth and clean, without welding scars, unevenness, or burrs.
The normal operating temperature for the 12 bag cage is 120-190 ℃, and the allowable operating temperature is 260-300 ℃.

The service life of the 13 organic silicon bag cage and dust removal skeleton is 2 filter bag replacement cycles, which is 60000 hours. During the service life, the surface organic silicon layer will not peel off
