Coating general knowledge: coating packaging: it is an international practice to measure liquid substances by volume

Core tip: several sets of wooden furniture ordered by Mr Li have been completed When preparing to buy wood paint, the worker calculated the volume of wood paint required for him However, when Mr Li selected wood paint, he found that several domestic brands he was interested in were all marked by weight rather than volume Mr Li wondered: should we buy according to the volume or the weight marked on the package?
It is an international practice to measure liquid substances by volume There are two ways to measure the volume and the weight of goods at the same time in the world and in China The international practice is liquid matter Paint agent, top 10 Chinese wall paint brands Recommended introduction: interior wall paint and exterior wall paint can achieve beautiful, clean and pleasant effects, but the effects in different environments are different, so the color of the paint will be different There are ten brands of Chinese paint, ten brands of global paint, ten brands of Chinese wall paint, and ten brands of Chinese paint, Famous trademark of Chinese paint and coating In private rooms, most of us choose according to our own personality, personal hobbies and living habits The younger generation will choose the interior wall paint with rich colors and bright colors, while the older ones will have some working experience Paint Home News: several sets of wooden furniture ordered by Mr Li have been completed When preparing to buy wood paint, the workers calculated the volume of wood paint needed for him However, when Mr Li selected wood paint, he found that several domestic brands he was interested in were all marked by weight rather than volume Mr Li wondered: should we buy according to the volume or the weight marked on the package? The measurement of liquid substances by volume is an international convention There are two ways of measurement, volume measurement and weight measurement, both at home and abroad The international common practice is to measure liquid substances by volume and solid substances by weight As a liquid coating product, most of the foreign coating companies sell by volume measurement, while most of the Chinese companies still trade by weight measurement No matter from the perspective of formulation design and product development of the coating itself, or from the perspective of customer convenience, we believe that the volume measurement of liquid coating is more in line with the modernization and scientific development of the industry Ding Zhi, director of comprehensive work department of China Coating Industry Association It is understood that the volume mark has been used for the measurement of coating product packaging by international multinational companies and domestic foreign companies However, most domestic coating enterprises, especially those producing civil decorative coating products (such as wood coating, latex paint, etc.), almost all adopt weight measurement, and the product packaging barrels are marked with 'kg' In a survey on the current measurement methods of coating enterprises just concluded by China Coating Industry Association, it has been found that the measurement by weight has become a kind of marking method used by domestic enterprises for a long time They think that when customers order at present, most orders are still shown by weight measurement table, and it's troublesome to change the packaging barrel identification into volume measurement, so most enterprises hope to Keep the status quo Huang Tianyuan, deputy director of Expert Committee of China Coating Industry Association, who participated in the investigation, said: 'at present, China's coating products have generally moved towards ISO international standards or equivalent adoption, and the adoption of international standards has become the development trend of China's coating product technical specifications The volume measurement of liquid coating is just a reflection of the internationalization of coating industry standard, which is convenient to unify with the international coating industry and realize the international connection According to Huang Tianyuan, the concentration and scale of China's coating industry are not high There are still thousands of small enterprises with annual output less than 1000 tons, mainly producing low-grade phenolic coating, alkyd coating and Matt water-based building coating In order to pursue economic benefits, quite a number of small enterprises often over add high density, low quality and low price fillers, such as barium sulfate, calcium carbonate, talcum powder, wollastonite, etc "If weight measurement is adopted, it will provide these small enterprises with the opportunity of rough manufacturing, counterfeiting and counterfeiting, reduce the performance of products, reduce the coating rate of products, thus damaging the interests of customers, causing a great waste of raw material resources, resulting in disordered development of the market, which is not conducive to the upgrading of coating products and the healthy development of the whole industry In addition, the weight measurement is not conducive to the quick and convenient calculation of the required coating amount in the project Before construction, according to the technical data, utilization density, solid content and other data provided by the coating manufacturer, according to the actual surface area, coating thickness and construction passes, the volume usage of the coating can be calculated conveniently and accurately But if it is measured by weight, it is difficult to calculate the demand of coating variety with technical parameters, which undoubtedly adds trouble to the formulation of construction scheme 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,
