Recently, the Green Furnishing Environmental Technology Industry Committee of China Interior Decoration Association (hereinafter referred to as the "Green Residential Committee") released the experimental results of the comparison of the environmental performance of the floor and the board, and also announced that the "Green Home Material 3G Logo" The "Procurement Specification" has passed the review of the Ministry of Commerce and will be officially implemented on December 1, 2013. In addition, dozens of well-known enterprises such as Hubei Baoyuan, Juran Home, Red Star Macalline, B & Q, Sacred Floor, Sofia (16.51, -0.04, -0.24%) wardrobe, living home floor, TATA wooden door, etc. were invited to join together Advocating "guaranteeing green households to practice social responsibility", for a time, the home furnishing industry set off a wave of "standardization" of plate.
Big brand flooring and sheet products have a high environmental compliance rate
It is understood that at the end of May this year, 28 consumer organizations in Beijing, Tianjin, Hebei, Liaoning, Shanghai and China Consumer News, a total of 29 consumer rights protection units, and the China Association of Interior Decoration Green Home Environmental Technology Working Committee, lasted In the past three months, a comparative test activity on the environmental performance of floors and boards was carried out. A total of 35 samples were tested in this comparative test, including 28 floor samples and 7 panel samples. Most of them are mainstream brands that are relatively popular in the market and rank well in the industry. Comparative test results show that, according to the national mandatory standard "Limits for Formaldehyde Emission in Interior Decoration Materials and Panels" (GB18580-2001), the compliance rate of formaldehyde emission for 35 samples is 97.14%. The overall environmental protection status of the floor and board represented by the company is relatively high, and the green environmental protection performance of the representative brand floor and board products is trustworthy.
Domestic commonly used plate is equivalent to international
In today's furniture industry, MDF and particle board are the world's most automated, most stable, and most mature artificial board varieties. In China's panel furniture industry, artificial materials such as MDF and particle board are also commonly used. These artificial boards are made from wood and its processing residues, separated and planed by fibers, rearranged and pressed together. It has all the excellent characteristics of wood, and overcomes some of the shortcomings of wood, so it has been widely used and favored in the furniture industry. China's wood-based panel technology was first introduced from abroad, and the national standards for related products were formulated at the early stage of introduction. After many amendments, especially after undergoing the mandatory national standard GB18580-2001 "Limits for Formaldehyde Emissions in Artificial Panels and Products of Interior Decoration Materials" and several major technical adjustments to adhesives, the performance and quality of artificial panels have been improved. A substantial increase. At present, the production technology of China's medium-density fiberboard and particleboard companies is quite mature, and some of them are comparable to foreign advanced levels. Many of the well-known international brands are also purchased in the Chinese market and manufactured in Chinese companies.
Need to improve product green monitoring system
It is reported that at present, most of the furniture panels in China have passed the license and environmental protection certification assessment, and branded furniture companies have basically selected high-quality products that have passed environmental label certification. "Ten Ring Certification" is China's most authoritative product environmental label certification. It implements strict national relevant standards and regulations, is consistent with internationally accepted product certification, and has reached mutual recognition cooperation with environmental label certification agencies in many countries and regions. It is a product certification worthy of consumer confidence. However, at present, there are many domestic manufacturers of wood-based panels, mainly small and medium-sized enterprises. The products are mixed, and certification is voluntary. Not all panels have passed environmental certification. Some manufacturers only need to meet the short-term standards to meet the inspection. Through some special chemical treatment methods, the formaldehyde emission in the short-term can be very low. Therefore, only standards are not enough. A complete certification system is also needed to ensure the implementation of standards, build a stable market competition order, and protect consumers' rights and interests to the greatest extent. In this regard, 29 consumer rights protection units jointly appealed that raising the environmental protection level of the plate from the source directly affects the quality of the product and directly affects the consumer's living environment. The plate production enterprises should raise environmental awareness, improve the product green monitoring system, and gradually Improve the production ratio of green sheet materials, cut off pollutants from the source, provide a high-quality material foundation for the environmental protection of green home products, and at the same time lay the foundation for consumers to enjoy true green home life.

Water Reducer mainly is used for cement in construction field. Used for and widely for self-cured, vapor-cured concrete and its formulations. At the early stageof application, extremely prominent effects are shown. As the result, the modulus and site utilization can be drastically, the procedure of vapor cure is omitted in peak-heatsummer days. Statistically 40-60 metric tons of coal will be preserved when a metric ton of the material is consumed.The new raw material is researched and produced by ourselves, which is mainly used in theproduction of polycarboxylate superplasticizer products.
Remarkable plasticity: as a condition of blending where amount of cement and collapsibility are fixed aforehand, mixing water can be decreased by 18-28% when it is admised with reinforced concrete at 0.5-1.0%. Ststistically, compression strendth on the 1st day, the 3rd day and the 28th day after single application is increased by 60-90% and 25-60% respectively when it is added at standard blend dosage. As the result, compression strength, tensile strength, bucking strgth and modulus of elasticity will be improved to some extent.
