The inorganic exterior wall coating is prepared by adding inorganic pigments as the main film-forming material, and then adding various pigments, fillers, additives and water. This kind of coating is mainly composed of water-soluble alkali metal silicate or water-dispersible silica colloid (commonly known as silica sol). The coating film has excellent weather resistance and is very stable under the action of ultraviolet rays; good heat resistance Sexuality, non-combustible and smoke-free in case of fire; better pollution resistance, not easy to absorb ash, can maintain a bright decorative effect; no volatile solvent is produced during production and use, it will not pollute the environment; its raw material resources are rich, mainly The material is the most abundant silica in the earth's crust, so it has received widespread attention. However, its coating film is not full and decorative, which limits its use. Inorganic architectural coatings are a category of waterborne architectural coatings with excellent performance, convenient use, environmental protection, and compliance with the development trend of high performance and low pollution of coatings.
How to buy:
Inorganic exterior wall coatings are mostly used in construction projects. Users should pay attention to the following points when purchasing:
1. Don't just consider the price factor, pay attention to the quality of the products, and purchase the exterior wall coatings of well-known enterprises that meet the requirements of national standards.
2, look at the appearance and logo, first of all to ensure that the packaging barrel is intact, especially in the seams or welds of the iron barrel should be no rust leakage; then look at the clearly marked on the packaging barrel, product model, name, batch number, Color number, standard number, weight, factory name, factory address, production date and expiration date should be complete.
3. Understand the main film-forming substances and precautions for construction of the purchased products. Inorganic exterior wall coating construction should pay attention to the following matters: Since inorganic exterior wall coating is made of inorganic material as film-forming substance, the adhesion to inorganic substrate is better, but on the construction of organic substrate, special attention should be paid to adhesion and related. Expansion coefficient, otherwise it will cause the coating film to peel off and fall off. Even if it is applied on an inorganic substrate, attention should be paid to the water absorption rate, pH value, presence or absence of cracks, and presence or absence of contamination of the substrate.
Special attention should be paid to the curing period of the coating. Due to the complicated reaction mechanism of the inorganic coating, it takes a long drying time, otherwise the expected performance will not be achieved. technical standard:
The test standard for inorganic exterior wall coatings is: JG/T26-2002 "External Wall Inorganic Architectural Coatings". The main technical performance indicators are: container state, construction, film appearance, contrast ratio, thermal stability, low temperature stability, dry time, scrub resistance, water resistance, alkali resistance, temperature resistance, coating resistance Staining, artificial aging resistance, etc.
