Frp Anti - Corrosion for Acid - Alkali Pools, Frp Anti - Corrosion for Sewage Pools, Professional Anti - Corrosion Construction Manufacturer
Fiberglass anticorrosive lining is the most common anti-corrosion treatment method. It uses a glass fiber reinforced plastic (commonly known as "fiberglass") structure to form a protective layer on the concrete foundation. Fiberglass anticorrosive lining has the characteristics of integrity, good impermeability and reasonable cost. At the same time, selecting appropriate anti-corrosion resin can achieve good anti-corrosion effects. In the fiberglass lining anti-corrosion construction method, a composite structure of glass fiber cloth plus glass fiber chopped strand mat or surface mat is generally used, with a thickness between 1 - 3mm. Fiberglass anticorrosive lining has the advantages of long-term water immersion resistance, low water permeability, strong adhesion, high water pressure resistance, acid and alkali corrosion resistance, anti-corrosion and mildew resistance, non-toxic and harmless, long service life, simple construction and no need for a protective layer.
Fiberglass anti-corrosion process: Epoxy resin, vinyl resin, unsaturated resin fiberglass anti-corrosion lining: The anti-corrosion and waterproof lining layer is made of resin and glass fiber cloth. Specific fiberglass anti-corrosion practices include one layer of cloth and three coats of paint (also known as one layer of cloth and three coatings, one layer of cloth and three adhesives), two layers of cloth and four coats of paint (coatings, adhesives), three layers of cloth and five coats of paint (coatings, adhesives), four layers of cloth and six coats of paint (coatings, adhesives), five layers of cloth and seven coats of paint (coatings, adhesives), six layers of cloth and eight coats of paint (coatings, adhesives), seven layers of cloth and nine coats of paint (coatings, adhesives), eight layers of cloth and ten coats of paint (coatings, adhesives), nine layers of cloth and eleven coats of paint (coatings, adhesives), ten layers of cloth and twelve coats of paint (coatings, adhesives), etc. (and so on, the number of paint, coatings, adhesives is two more times than that of the cloth).
Scope of application: Anti-corrosion construction for concrete treatment pools, ditches, floors and walls that require protection against strong acid and strong alkali chemical solvents; various steel containers; the surface of various metal equipment foundations, etc. It is widely applicable to the acid, alkali and salt resistant workshops, warehouses, storage tanks, walls, floors, sewage treatment pools and other facilities in industries such as medicine, chemical industry, machinery, light industry, electronics, power plants, battery factories, electroplating factories, aluminum factories, metallurgical factories, etc.
Thickness: 1.0 - 3.0mm;
Surface form: Rolled finish type, glossy finish type;
Service life: 5 - 15 years.
Performance characteristics:
1. Vinyl ester resin has the superior physical properties of epoxy resin and the rapid hardening of unsaturated polyester, with simple and convenient processing and forming properties
2. Excellent chemical resistance, able to resist the corrosion of most salts, acids and alkali chemical reagents below 1000℃;
3. Particularly suitable for work surfaces and workplaces with heavy anti-corrosion requirements, such as working environments like strong acid and alkali pool sewage trenches;
4. Excellent mechanical properties, toughness and fatigue resistance.
Scope of application:
1. Electroplating factories, battery factories, chemical factories;
2. Chemical storage areas or barrels, large water tanks, electrolytic cells, etc.;
3. Sewage and wastewater treatment tanks, acid-base neutralization tanks.
Construction process:
1. Waterproof treatment: The first-floor ground needs to have been waterproofed;
2. Substrate treatment: Sand, repair, and remove dust according to the substrate condition;
3. Vinyl ester floor paint primer: Add the accelerator and curing agent to the vinyl ester resin in an appropriate proportion, and apply a thin coat on the substrate to enhance surface adhesion;
4. Lay fiberglass cloth: Lay the fiberglass cloth flat, adhere the fiberglass cloth to the ground with the prepared vinyl ester intermediate coat, and level the vinyl ester intermediate coat with a putty knife to make it evenly coated. Do one to three layers according to the design;
5. Vinyl ester intermediate coat: Evenly apply the prepared vinyl ester intermediate coat with a trowel for one to two coats;
6. Vinyl ester floor paint topcoat: Evenly apply the prepared vinyl ester topcoat with a roller. After completion, the overall ground is bright and clean, with uniform color and no hollowing;
7. Construction completion: People can enter after 24 hours, and heavy pressure can be applied after 72 hours (based on 25 degrees. The opening time needs to be appropriately extended at low temperatures).
