Diatom mud purchase: the latest diatom mud purchase news good products do not add nano titanium dioxide

Core tip: for the method of how to choose diatom mud products, we mostly stay in the simple evaluation of its water absorption and fire resistance, and then the high-end point is to see how high the decomposition degree of formaldehyde is Today, Xiaobian wants to lead you to use the high-level vision of professionals to examine diatom mud products and make safe choices Recently, TV media and Internet media have paid close attention to diatom mud industry The reporter recently interviewed many professionals in the industry Some manufacturers mentioned photocatalysts What kind of substance is photocatalyst? Photocatalyst is a general term of photocatalysis materials, which are coated on the substrate surface 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 Home of coatings news: about how to choose diatom mud products, we mostly stay in the simple evaluation of its water absorption and fire resistance, and then the high-end point is to see how high its decomposition of formaldehyde Today, Xiaobian wants to lead you to use the high-level vision of professionals to examine diatom mud products and make safe choices Recently, TV media and Internet media have paid close attention to diatom mud industry The reporter recently interviewed many professionals in the industry Some manufacturers mentioned photocatalysts What kind of substance is photocatalyst? Photocatalyst is the general term of a kind of photocatalysis material It is coated on the surface of substrate, and under the action of light, it has the function of catalytic degradation Among them, titanium dioxide is one of the catalyst materials A number of experts in the industry said that titanium dioxide's air purification effect is achieved by using the photocatalyst mechanism, that is, with the help of sunlight (UV), some harmful substances are decomposed, and then the harmful substances are washed out by rain, so it is generally used for the outer wall The latest diatom mud, good news, no nano titanium dioxide (photo from the Internet) and little UV light in the room Moreover, if people are exposed to ultraviolet light for a long time, they are easy to get skin cancer Even if there is, the light is weak and the exposure time is short, which can't purify the air Besides the bathroom, it's impossible to wash the wall with water, so the air purification effect is almost unexpected Therefore, titanium dioxide is generally only used in exterior wall goods Among them, nano titanium dioxide also has this catalytic degradation effect However, the safety of nano titanium dioxide to human body has been controversial in the world It is for the above reasons that a few enterprises with strong technology R & D capabilities in the industry insist on not adding nano titanium dioxide into diatom mud, but adding inorganic minerals with catalytic effect and other composite functional additives The catalysis between inorganic minerals is not limited by ultraviolet radiation, and will occur catalytic decomposition for a long time The purification effect of diatom sludge on air is mainly measured from the following two aspects: formaldehyde purification efficiency and formaldehyde purification durability The diatom mud added with inorganic minerals and other compound functional additives with catalytic effect greatly improved the durability of formaldehyde purification More importantly, a good diatom mud product should first ensure the environmental protection of the product itself The environmental protection performance of products depends on the authoritative test reports at home and abroad, including national standards, industrial standards and international standards Generally speaking, the standard for diatom mud products is F4 star superior to EO standard, EO standard superior to the industry standard of "diatom mud decorative wall material", and diatom mud industry standard superior to the national standard The following is the comparison of domestic and foreign standards: through the above comparison, we can see that the emission limit of F4 star for free formaldehyde is 0.12mg/l, which is the most stringent environmental protection standard in the world F 4-star products have no use area limitation; F 3-star products can only be used within the range of less than 2 times of the ground area If the ground area is 10 square meters and the roof area is 10 square meters, the wall area cannot exceed 10 square meters; EO standard is equivalent to F2 star products F2 star products can only be used within 0.3 times of the floor area If the floor area is 10 square meters, the wall area cannot exceed 3 square meters For a good diatom mud, first of all, it depends on its environmental protection When purchasing, it needs to recognize the F4 star certification Secondly, it needs to see the formaldehyde purification efficiency and durability When purchasing, it must ask the manufacturer for the national authoritative test report in this respect Home of coatings focuses on the news and information of coatings, diatom mud, paint coatings, coating process, fire retardant coatings and coatings, paint coatings, coating process, decoration knowledge and decoration effect map of fire retardant coatings,
