Core tip: one of the current interior wall coatings is low-grade water-soluble coating, which is made by dissolving polyvinyl alcohol in water and adding pigments and other additives In order to improve its performance and reduce its cost, a variety of ways have been adopted, with many brands The main products are 106, 107803 interior wall coating The disadvantage of this coating is that it is not water-resistant and alkali resistant The coating is easy to peel off after being damped It is a low-grade interior wall coating and suitable for general interior wall decoration This kind of coating has the advantages of low price, non-toxic, odorless and convenient construction The powder can't be wiped dry, because the film-forming material is water-soluble, so there are always some traces left after scrubbing with a wet cloth Application scope and advantages of roller ceramic coating Recommended introduction: the surface of ceramic rubber plate used for roller ceramic coating is cast into durable rubber plate by hundreds of independent small ceramic pieces Each ceramic piece has raised characteristics Under general conveyor belt pressure, thousands of unique cast bumps can produce positive traction, prevent slipping and extend the service life of conveyor belt roller At the same time, the bottom layer adopts high-quality rubber, which has strong elasticity and can play a good impact resistance role The scope of application of roller ceramic coating is one three six 83857180 (the same as V) 1 Roller coating in extremely harsh working environment 2 The belt joint is not suitable for fixing with iron buckle; 3 It is suitable for leather Paint Home News: one of the current interior decoration interior wall coatings are low-grade water-soluble coatings, which are made by dissolving polyvinyl alcohol in water and adding pigments and other additives In order to improve its performance and reduce its cost, a variety of ways have been adopted, with many brands The main products are 106, 107803 interior wall coating The disadvantage of this coating is that it is not water-resistant and alkali resistant The coating is easy to peel off after being damped It is a low-grade interior wall coating and suitable for general interior wall decoration This kind of coating has the advantages of low price, non-toxic, odorless and convenient construction Dry wipe powder, because its film-forming material is water-soluble, so with a wet cloth after scrubbing always leave some traces, durability is not good, easy yellow color, but its price is cheap, construction is also very convenient, the current consumption is still the largest, about 50% of the market, mostly for low-end or temporary indoor wall decoration The second type is emulsion paint, which is made of acrylate, styrene acrylate copolymer, vinyl acetate polymer aqueous solution as film-forming substance and adding a variety of auxiliary components The film-forming substance is insoluble in water, and the film is coated Compared with the first type, the water resistance and weather resistance of the product are greatly improved, leaving no trace after wet scrubbing, and there are different decoration types such as flat light and high light Due to its less colors, the decoration effect is similar to 106 kinds In fact, these two kinds of coatings are not of the same grade at all They belong to the middle and high-grade coatings Although their prices are relatively expensive, they occupy a larger and larger market share due to their excellent performance and decorative effect Good latex coating layer has good water resistance, alkali resistance, scrub resistance, and the coating will never peel off after being damped Generally speaking (under the same conditions of pigment, volume and concentration), styrene acrylic emulsion paint has better water resistance, alkali resistance and scrub resistance than ethylene acrylic emulsion paint, and ethylene acrylic emulsion paint is better than polyvinyl acetate emulsion paint (commonly known as emulsion paint) The third type is a very popular multi-color coating The film-forming material of the coating is nitrocellulose, which is dispersed in the water phase in the form of oil in water A spray can form a variety of color patterns In recent years, another kind of porcelain like coating has appeared, which belongs to the fourth category Its decoration effect is delicate, bright and clean, elegant, and the price is not high, but the construction technology is complex, and the wet rub resistance is poor Two how to judge whether the latex paint is good or bad after opening the lid, the real environment-friendly latex paint should be waterborne non-toxic and tasteless, so if the user smells, if it has pungent odor or industrial flavor, it is not an ideal choice After a period of time, the surface of the genuine latex paint will form a very thick elastic oxide film, which is not easy to crack, while the defective paint will only form a very thin film, which is fragile and has a pungent smell Mix the emulsion paint with a wooden stick, and pick it up with a wooden stick When the high-quality emulsion paint flows down, it will form a fan shape Touch with your fingers, the genuine latex paint should feel smooth and delicate The real latex paint has no irritating smell, and the low-grade water-soluble coating of fake latex paint may contain formaldehyde, so it has a strong irritating taste Secondly, a little paint can be brushed on the cement wall After the coating is dry, it can be scrubbed with a wet cloth The real latex paint has a strong scrubbing resistance, and one or two hundred times of scrubbing will not have a significant impact on the appearance of the coating, while the low-grade water-soluble paint only has a dozen times of scrubbing, which will cause the fading phenomenon of powder falling and exposed bottom Emulsion paint is applied to the wall, and the color of the authentic product is as bright as new In the purchase to see the composition, the composition of high-quality paint should be copolymer resin or pure acrylic resin Don't forget to look at the shelf life of the product Why three emulsion paint is much better than solvent paint? Emulsion paint is water-based paint Its film performance is much better than solvent paint The organic solvent, which accounts for half of solvent paint, is replaced by water here Therefore, the toxicity of organic solvent is basically solved by emulsion paint Emulsion paint is made of some polymer aqueous solution In addition to water and different types of safe and harmless polymers or polymers, it also contains a small amount of emulsifier and a small amount of unpolymerized free monomers Free monomers are some volatile small molecular substances with different degrees of toxicity Now the concentration of free monomers of environmental protection paint is controlled below 0.1%, and the use of auxiliaries is under control 2% to 3% of them are in large quantity, and only 0.05% to 0.1% of them are in small quantity At present, the toxic concentration of free monomers and the amount of additives used in inferior latex paint exceed the standard by dozens or hundreds of times, which affects the health Now the commonly used lipang and Dulux paints have reached the specified environmental protection standards and are safe At present, there are a lot of latex paint brands in the market, and the imported and domestic products are on the same pace, with fierce competition The domestic brands with guaranteed quality and good reputation are Hongshi and Kelan; the imported brands are duluxi, Libang paint, Laiwei paint, etc The washability of these brands is generally no less than 300 times, some as high as 2000 times If the imported brand is a "green product", there is an international certification mark on the outer package, for example, Germany is a "Blue Angel" sign; the domestic product can only be called a "green product" if it has the word "product certified by China Environmental Labeling Product Certification Committee" 4 Comparison between imported latex paint and domestic latex paint; at present, imported latex paint in the market belongs to high-grade and high-priced paint It is only slightly better than domestic latex paint in leveling, fineness, color matching and can opening state Other indexes are comparable, but the price is 1? D2 times higher than domestic latex paint There are some misunderstandings about the use of imported latex paint For example, one kilogram of latex paint can be brushed over 8 square meters, which is intended to tell people that the cost per square meter is not more expensive than that of domestic latex paint But one kilogram is impossible to brush such a large area The coating is too thin to guarantee other properties Generally 1 kg paint brush 5 square meters is not less Moreover, some imported latex paints are actually produced by domestic joint ventures and are labeled with the trademarks of foreign companies But the domestic latex paint also has many good quality, but the price is much lower than the imported paint, for the general family, it is more suitable The best choice for home decoration is interior wall emulsion paint Five, how to choose the latex paint according to the different parts of painting is very important We should choose the latex paint according to the different parts of painting For example, the latex paint used on the walls of bedrooms and living rooms should have strong adhesion, fine texture, good resistance to differentiation and permeability The latex paint used in kitchens and bathrooms should be waterproof, mildew proof and easy to wash The bedroom uses polyvinyl acetate (commonly known as emulsion paint), but the kitchen, toilet and balcony ceiling parts susceptible to moisture should choose more scrub resistant paint, strong ethylene propylene or styrene propylene emulsion paint Six construction should pay attention to what latex paint before construction, the wall must be handled well, otherwise the latex paint will cause serious problems such as falling off, cracking, blistering and so on At present, many people still use 821 putty in construction In fact, 821 putty is very water-resistant When the wall contains water, 821 putty will absorb water and blister, which will cause large area blistering and falling off of latex paint And the better the performance of latex paint, the better the film-forming property, the more serious the problem Therefore, when using emulsion paint, first use the back cover to seal the wall, and then use water-resistant putty to avoid the above problems During the construction of emulsion paint, it should be stirred evenly, especially when using bright colored products If not stirred evenly, when the color paste in the paint is not stable or precipitated due to long-term storage, the construction will cause the decorative effect to be affected seriously In addition, whether and how much water can be added during latex paint construction must be strictly in accordance with the manufacturer's regulations Because some manufacturers in the design and development of latex paint, have fully considered the needs of users, designed a variety of formulas, some latex paint in the construction of water, water instead of breaking the various properties of the latex paint It should be noted that brush coating, roller coating and spray coating can be used in the construction Either of the above methods can achieve the expected effect, but the viscosity of the emulsion paint should be adjusted to make it easy to brush during the construction, and there is no obvious brush mark after brushing If the viscosity is too large, the brush mark is obvious, and the viscosity is too low, it is easy to cause slag flow and poor covering power After construction, tools shall be cleaned with water in time, otherwise, it will be difficult to clean the emulsion paint after drying due to its water resistance Can I paint the interior wall with the exterior wall paint? According to the experts, it's OK to paint the interior wall with the exterior wall paint from the perspective of environmental protection, but it's not necessary to paint the exterior wall with the interior wall paint According to the introduction, internal and external wall latex paint have their own special requirements External wall latex paint is used for painting on the building facade, so the most important index is anti ultraviolet radiation, to achieve long-term exposure without discoloration The interior wall paint is used for interior wall painting The UV resistance requirement is much lower than that of the exterior wall paint The interior wall latex paint has a high performance requirement for scrubbing resistance It is easy to stain the wall in home life and can be wiped with water at any time The external wall shall be water resistant and self-cleaning The paint film shall be hard and flat, and the dirt shall be washed away as soon as possible The elasticity of interior and exterior wall paint is very important Elasticity can prevent cracking caused by temperature and climate change Exterior wall paint can be used for interior wall painting because it also has water resistance, while interior wall paint does not have sun resistance, so it cannot be used for exterior wall painting, but experts suggest that it is better to use it for special purpose The interior and exterior wall paint have the same requirements for environmental protection People raised the question "whether the exterior wall paint can be used to brush the interior wall", mainly concerned about environmental protection, and worried about the low environmental protection index of the exterior wall paint, which will cause indoor air pollution In fact, as long as it is latex paint, whether it is interior wall paint or exterior wall paint, there is no pollution Home of coatings is specialized in coatings, diatom mud, paint coating, coating technology, fire retardant coating news and coating, diatom mud, paint coating, coating technology, fire retardant coating decoration knowledge and decoration renderings,
