Paint is a special main material in home decoration. It is a coating material applied to the surface of the object with protective properties, decorative properties or other special properties. The most commonly used coatings in home decoration are wall paint and wood paint. . In general home decoration, the expenditure of paint only accounts for about 5% of the entire renovation cost, but it accounts for 80% of the entire decoration area. 100% determines the overall decoration effect and the living room environment, which directly affects the health of the family. A special place in home renovation. Therefore, Xiao Bian reminds the owners to be very cautious when purchasing paint, so as not to affect the future residence.
There are many types of coatings, but there is no uniform division method. There are usually the following classifications: 1. Classification according to the shape of architectural coatings (1) Liquid coatings (2) Powder coatings, etc. 2. Classification according to the nature of major film-forming substances (1) Organic materials (2) inorganic coatings (3) organic-inorganic composite coatings; 3, according to the state of the coating film classification (1) plane coatings (2) color sand coatings (3) multi-layer coatings; 4, by construction Use of materials (1) exterior wall material (2) interior wall coating (3) ceiling coating (4) floor coating (5) roof coating; 5, classification by performance of coating film (1) waterproof coating (2) fire protection Coating (3) anti-corrosion coating (4) anti-mold coating (5) insect-repellent coating (6) rust-proof coating (7) anti-condensation coating.
Paint selection method:
How to choose a home decoration paint brand that is consistent with the overall decoration style of the home decoration room. The home improvement paint that is both healthy and environmentally friendly is a problem that the decorator is very concerned about. When purchasing home improvement paints, be sure to pay attention to the following options:
1. Try to go to the formal market or specialty store with heavy credit to buy, mainly because the quality of the interior wall paints sold by these enterprises is higher than the results of the supervision and inspection conducted by the Municipal Quality and Technical Supervision Bureau in recent years.
2. Recognize the logo on the product packaging when purchasing, especially the factory name, factory address, product standard number, production date, expiration date and product instruction manual. It is best to purchase products that have passed ISO14001 and ISO9000 system certification. The quality of these products is relatively stable and there are no quality problems.
3. Purchase products that meet the “GB18582-2001 Interior Decoration Materials Interior Wall Coatings Hazardous Substances Limits†standard and obtain environmental certification marks.
4. When purchasing, pay attention to observe whether the packaging container of the product is damaged or inflated. Shake it at the time of purchase to check for cementation. If the paint appears, it cannot be purchased.
5, usually most paint can not be opened on the spot to check the intrinsic quality of the product, so consumers must ask for valid invoices such as invoices and construction instructions when purchasing.
In addition, the corresponding paint can be selected according to local conditions. For example, a room with a large flow of people should use a paint with good pollution resistance, aging resistance and good color retention, such as strong stain resistance and good color retention. The paint is especially suitable for the living room wall; according to the climatic characteristics, the south should use the paint with good moisture resistance and mildew resistance; in the north, the paint with low temperature resistance and good construction property should be selected.
Indoor paint purchase principle:
Interior wall decorative coating is one of the main materials of home decoration. The selection of interior wall coating generally has the following principles:
1. Consider functional requirements: different functional areas have different requirements for coatings. For example, kitchens, bathrooms and other tidal parts should use coatings with good water resistance. The bedroom, living room and other parts should be selected with good decorative effect, fine layers, paint with certain scrub resistance, colorful paint and so on.
2, consider the decorative effect: as an interior wall paint, the decorative effect is very important. Because this is to choose a layer that is delicate and durable, the color is light and fresh, and at the same time it must be coordinated with the color of the furniture.
3, consider the coating performance and construction conditions: it is generally believed that home decoration should give priority to single-component soluble coatings, the construction method is best to brush. These materials have low odor and are easy to operate. If solvent-based coatings are used, better ventilation is required. If you choose two-component materials, you should pay attention to the accuracy of the ratio, and the second should be used within the specified time, and can not be stored for a long time.
4. Choose different coatings for different base layers: such as concrete and cement base, the coatings are required to have good alkali resistance and opacity. Optional latex paint, scrub resistant interior paint, colorful pattern paint, etc. Do not choose melamine paint for lime and plaster walls. Non-alkaline coatings should be used on the wooden base.
1, strong, thermostable
Because CPVC compares PP-R, PE-X to be firm. Compared with PP, the PE-X tube, under the similar pressure, CPVC may use a smaller caliber to achieve the same water flow, thereby saving material costs and installation time. Compares with other thermoplastic, CPVC has the remarkable mechanical property under the different temperature, is suitable for the bearing the situation, the application temperature may reach as high as 93°C, the life may amount to 50 years.
2, easy installation
The connection method are very similar with PVC. Most commonly used and simple connection method is resolver cementation. Other connection methods are threaded connection, flange connection and electrode connections.
3, non-corrosive oxygen permeability
CPVC have the anti-oxygen, therefore the oxygen seepage from the radiator will not bring metal corrosion.
4, reducing the infiltration of additives
In order to prevent oxidation, some modified plastics needs to increase the massive antioxidant that may be infiltrated into the water supply system ,causing the ill-smelling smell.
5, without the impact of chlorine in water
A lot of polyolefin materials (including PP, PE) may be decomposed with water, while CPVC is not affected by the impact of residual chlorine in water that there is no cracks and leakage.
6, good flame retardancy
CPVC limiting oxygen index is 60, therefore it will not burn in the air. It has the characteristics : misfires the flame decoction,not to increase the fire set,restrict flame spread,low smoke generation. 7, CPVC has excellent chemical resistance to non-polar strong acid and alkali. Commonly used to substitute the metal to process the corrosive material, such as the poor quality of water, acidic material alkaline matter and other peroxide solutions.
8, the low thermal conductivity
CPVC thermal conductivity is only 1.05. heat is not easy to disseminate from the pipeline, heat loss of pipeline is low.
9, bacteria breeding is not easy
CPVC is not influenced by the impact of residual chlorine in water. So it will not result in cracks and leaks. Inner wall of pipe is smooth, not easy to breed bacteria. The research indicated that the breeding of germs in CPVC pipe is far lower than other materials such as copper, steel and other plastic pipe.
10, low thermal expansion
CPVC thermal-expansion coefficient is lower than other plastics. The tube expansion is very small when tube-pass heat, unlike other types of channels (such as PP-RRP) due to the higher temperature caused by heat expansion coefficient that could cause snake bending,the existence safe hidden danger and eyesores.
11, the test of time
none of a thermoplastic material such as CPVC,avoid the maintenance after 40 year hot water system's test, and displays its excellent performance
