Abstract

The utility model provides GRP corrosion-resistant water treatment equipment which can solve the problems in the prior art that the corrosion resistance of equipment is valid for a short time and the corrosion-resistant coating is caduceus. Four layers of epoxy resin (1) and two layers of degreased and dewaxed medium alkali glass fiber fabric (2) are applied on the material surface of the water treatment equipment (3) to form a GRP corrosion-resistant lining, of which the thickness ranges from 0.7 to 1.3mm. The lining has the advantages of low hydraulic permeability, bright and clean surface, high compression strength, long corrosion-resistant service life and convenience and simplicity in construction, can effectively prevent air and water from being in contact with the material of the protected equipment, is harmless and nonpoisonous, and prevents the breeding of water-based creatures.

Description

The anticorrosion water treatment facilities of fiberglass

Technical field

The utility model relates to the anticorrosion water treatment facilities of a kind of fiberglass, is mainly used in the long-effective corrosion aspect of water treatment facilities.

Background technology

The equipment body of water treatment facilities is mostly by the mild steel manufacturing, rust corrosion very easily under the situation of long-term contact water and air, and therefore problem such as polluted source occurs or leak must carry out anti-corrosion measure at the surfaces externally and internally of equipment.

In the prior art, the anti-corrosion measure of the equipment inside and outside wall of water treatment facilities generally is the brushing corrosion resistant coating, be about to clean, the dry back of equipment body inside and outside wall cleaning surfaces and apply corrosion resistant coating, as epoxy anticorrosive paint, polyurethane anti-corrosion paint and acrylic acid corrosion resistant coating etc., yet, because corrosion resistant coating is formed by the material combination that pigment, filler etc. very easily contains noxious material usually, so be difficult to reach sanitary standard; Owing to mostly being the organic granular bonding, paint itself forms on the other hand, be subjected to the service life of anticorrosive coat raw material, temperature, illumination effect bigger, general service life is shorter, between 2～5 years, the brushing corrosion resistant coating must be repaired once more then, also equipment and materials or parts must be changed in case of necessity.

Summary of the invention

The utility model provides a kind of fiberglass anticorrosion water treatment facilities, can solve short, the caducous problem of anticorrosion coating of equipment anticorrosion life-span that prior art exists.

For achieving the above object, the utility model is achieved by the following technical solutions: apply the medium alkali fiber cloth (2) of four road epoxy resin (1), two pull-up fat dewaxing at water treatment facilities (3) material surface, form the thick anticorrosion lining of fiberglass of 0.7-1.3mm.

Compared with prior art, advantage of the present utility model and good effect are:

1, the fiberglass that anticorrosive coat adopted of the utility model water treatment facilities all has resistivity preferably to acid, alkali, salt and multiple oils and the solvent of atmosphere, water and general concentration, therefore the fiberglass anticorrosive coat have nontoxic, tasteless, to the good characteristic of water quality non-secondary pollution, can guarantee the water outlet safety and sanitation.

2, the epoxy bond intensity height that anticorrosive coat adopted of the utility model water treatment facilities, chemical mediators such as soda acid are had certain stability, so anticorrosion coating difficult drop-off, long service life.

Description of drawings

Accompanying drawing is the generalized section of the utility model frp liner.

Among the figure: 1, epoxy resin; 2, medium alkali fiber cloth; 3, water treatment facilities material; H, anticorrosion lining gross thickness.

The specific embodiment

For the purpose, technical scheme and the advantage that make the utility model embodiment is clearer,, the technical scheme among the utility model embodiment is clearly and completely described below in conjunction with the accompanying drawing among the utility model embodiment.

Particularly, the enforcement of the anticorrosion water treatment facilities of fiberglass in the present embodiment, specifically can carry out according to the following steps:

1, the water treatment facilities material surface is carried out blasting treatment, cleannes reach Sa2.5, and roughness reaches 40～70 μ m;

2, apply four road epoxy resin at the water treatment facilities material surface, two layers of medium alkali fiber cloth, order is to be from inside to outside: epoxy resin, medium alkali fiber cloth, epoxy resin, medium alkali fiber cloth, epoxy resin, epoxy resin reach between the 0.7-1.3mm anticorrosion lining gross thickness.

Claims

1. anticorrosion water treatment facilities of fiberglass is characterized in that: apply the medium alkali fiber cloth (2) of four road epoxy resin (1), the dewaxing of two pull-up fat at equipment (3) material surface, form the thick anticorrosion lining of fiberglass of 0.7-1.3mm.
