Novel surface treatment process for filter press

Abstract

The invention relates to a novel surface treatment process for a filter press, and the novel surface treatment process can be suitable for various strong-corrosion environments, can shorten the production period, and can save cost. The novel surface treatment process comprises the following steps of: separately performing shot blasting treatment on a thrust plate body, a main beam, a pressing plate body, an oil cylinder base and oil cylinder base supporting legs, wherein surface clearness of each shot-blast part is Sa2.5 grade, and roughness is 30-70 microns; separating adopting epoxy paint toperform roller-brushing treatment and surface-drying on the inner surface of the oil cylinder base, the guide rail surface of the main beam, the outer surface of the oil cylinder, contact surfaces between the oil cylinder base and the oil cylinder base supporting legs, and a clamping base between the thrust plate body and the oil cylinder base; and performing integral roller-coating treatment onthe surface of the rack of the assembled filter press. The novel surface treatment process for the filter press has the advantages that: firstly, the novel surface treatment process for the filter press is relatively environmentally-friendly, and the filter press treated by the novel surface treatment process has super-strong corrosion resistance, and can be suitable for various strong-corrosion environments; and secondly, the novel surface treatment process for the filter press is simple in process, and can greatly shorten the production period of the filter press.

Description

technical field [0001] The invention relates to a novel filter press surface treatment process which can adapt to various strongly corrosive environments, shorten the production cycle and save costs, and belongs to the field of filter press manufacture. Background technique [0002] The existing filter press surface treatment processes include primer plus topcoat, stainless steel coating, glass fiber coating, glass fiber reinforced plastic coating, and rotary molding. For the models with serious and harsh use environments, generally the surface of the filter press is made of stainless steel, rotational molding or glass fiber reinforced plastic anti-corrosion treatment process. The production of stainless steel cladding process is not only high in cost and long in production cycle, but also not suitable for some materials. The surface treatment process of rotational molding and glass cladding is complicated and not environmentally friendly, and it is easy to cause certain po...
