Core tip: yesterday, the provincial consumer committee announced the results of home decoration material comparison test The results show that the overall quality of waterproof materials for home decoration is not considerable The unqualified products in 26 batches are 9 batches, and the unqualified rate is more than 30% However, 11 batches of interior wall emulsion paint are all up to the standard, but there are still some problems such as false propaganda The test results show that there are many problems with waterproof materials Among them, the quality of polymer cement waterproof coating is poor, including Xinhe waterproof coating, Yunyu waterproof coating and gambling waterproof coating The compliance rate of composite resin sheet is very low Among the 5 batches of samples, 4 batches fail to meet the standard, namely, nominal Xiling, Haoyu and Fulong Several ways of roller coating Recommended introduction: roller coating includes rubber roller coating, insert plate roller coating and ceramic rubber roller coating The following is a detailed introduction of these three ways of coating The function of roller rubber coating is to increase the friction derivative between the conveyor belt and the cylinder surface during transmission, so as to reduce the friction coefficient of the conveyor belt on the cylinder surface, reduce the mutual wear of the sliding machine of the conveyor belt on the cylinder surface, improve the traction force during operation, and extend the service life of the conveyor belt and the electric roller One, three, six, 8385-7180 (V) rubber rollers are covered with diamond rollers and flat rollers, generally pure rubber plates The rubber coating of the inserted plate roller is divided into tile shell type roller and Paint Home News: yesterday, the provincial consumer committee announced the results of home decoration materials comparison test The results show that the overall quality of waterproof materials for home decoration is not considerable The unqualified products in 26 batches are 9 batches, and the unqualified rate is more than 30% However, 11 batches of interior wall emulsion paint are all up to the standard, but there are still some problems such as false propaganda The test results show that there are many problems with waterproof materials Among them, the quality of polymer cement waterproof coating is poor, including Xinhe waterproof coating, Yunyu waterproof coating and gambling waterproof coating The compliance rate of composite resin sheet is very low Among the five batches of samples, there are four batches that do not meet the standard, namely the products of nominal Xiling, Haoyu, Fulong and Shengdu The existing problems are that all the product marks do not meet the requirements of the national compulsory standards, and lack of production date, standard specifications and other contents According to the provincial people's Committee, in the market, many operators claim that the interior wall latex paint products have the effect of adsorption and decomposition of formaldehyde In fact, it is found that the so-called nominal "formaldehyde resistant" latex paint itself also contains formaldehyde, and even the measured value of free formaldehyde is relatively high 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,
