How about painting the TV tower?

It's good and cheap. How to choose environmental protection coatings for Guangdong famous \x0d\? The following is for reference. \ x0d \ x0d \ The popular paint decoration in the market now actually includes two categories of products. One is wood paint with oily solvent, which is used to brush furniture and floors, referred to as paint; One is a wall paint with water as solvent, also called latex paint. Paint decoration accounts for a small proportion of the house decoration expenses of a family unit, but it is very important. Because it is the last process, the beauty and comfort of house decoration depend on this process. The last process is not done well, not only looks ugly, but also uncomfortable to live in. It may even bring adverse consequences to the health of family members because of improper selection of coatings. \x0d\ Visiting the building materials market, there are four or five hundred coating brands, which is the best? Which is the worst? Due to the particularity of paint properties, it is generally difficult to distinguish clearly. Here I briefly introduce a little regularity from two aspects. \x0d\ 1. What is a good pigment? \x0d\ 1。 First of all, in terms of performance, good coatings have high solid content and low volatile solvent VOC content. It is more cost-effective to buy a coating with high solid content, which has a large brushing area or a thicker and fuller paint film with the same area. At present, the solid content of different coatings on the market is very different. Paint with low solid content may be cheaper, but if you want to brush to the same thickness and fullness, you must buy more; Or buy the same amount of paint and apply only a thin layer. The thickness and fullness of the paint film are not enough. Secondly, good coatings have high hardness, good wear resistance and stronger adhesion to the substrate, so the service life of such coatings is longer. \x0d\3。 Third, a good coating has better transparency and can fully reflect the characteristics of the substrate. \x0d\4。 Fourth, good paint has better yellowing resistance and lasts as long as new. \x0d\5。 Fifth, a good coating has better construction performance and smoother and more beautiful film. \x0d\6。 Sixth, a good paint solvent evaporates quickly, and you can't smell anything after painting for a few days. I would like to remind you that some pigments are a little fragrant. In fact, it is not the best coating, because the toluene and xylene aromatic substances contained in this coating are still toxic. A really good paint is the kind that makes your nose a little choked when you apply it after opening the can, but it doesn't smell after a day or two. \x0d\7。 Finally, and most importantly, it is the environmental protection performance of the paint. The content of toxic and harmful substances in good paint is very low. Toxic and harmful substances in paint include volatile solvents such as VOC, benzene, toluene and xylene, heavy metals such as lead, mercury and cadmium, and free TDI. These substances are very harmful to human body, especially children's body, so there are very strict requirements for the content of these substances in paints in the national mandatory standards. Guangdong Pasteur Chemical Co., Ltd. introduced the "full-effect paint decoration" to the market, in which the contents of benzene, toluene and xylene, as well as the contents of heavy metals are controlled in a very low range that cannot be detected by the most advanced testing instruments; The content of free TDI is controlled within 0. 1%, which is far lower than the national mandatory standard of 0.7%. This is the closest coating product to environmental protection requirements on the market at present. \ x0d \ x0d \ Secondly, how to choose good coatings? \x0d\ 1。 The first is based on the introduction of authoritative departments. From the General Administration of Quality Supervision, Inspection and Quarantine (AQSIQ) to the quality inspection departments at all levels in provinces and cities, the quality of paint products on the market will be spot-checked every year, and the results will be published in newspapers, television and websites. \x0d\ \x0d\2。 Secondly, it depends on whether the enterprises that produce coatings have really passed various certifications. The certification of paint manufacturers is mainly ISO900 1:2000: 2000 international quality system certification, as well as Chinese environmental mark certification of water-based wall paint and III environmental mark certification of paint. \x0d\\x0d\3。 Third, look at the product inspection report. Whether there is a product-related quality inspection report issued by an authoritative quality inspection department is one of the important basis for judging paint quality. \ x0d \ x0d \ 4。 Fourth, look at the packaging and publicity materials of coatings. The detailed description of packaging and publicity materials shows that the enterprise is strict in management and conscientious in doing things. If the address on the packaging and materials is incomplete, the data is unclear, or even the handwriting is unclear, then this enterprise must be lax in management and sloppy in doing things. \x0d\ \x0d\5。 Fifth, do not be superstitious about foreign brands. In terms of environmental protection, good domestic brands are no worse than foreign brands; Hardness and fullness of paint, scrub resistance and weather resistance of wall coating. Some domestic brands are even better than foreign brands. \x0d\ Sixth, we should decorate it reasonably. For example, choose to designate a paint brand and adopt the way of signing a painter; Entrust the painting work to the paint dealer; Entrust a qualified decoration company to paint and so on. In this way, you can choose to use the paint of assured brand, which can avoid the rebate when buying paint and save the decoration cost.
