The above-mentioned agreement was reached on the evening of the 21st by representatives of the twentieth anniversary of the conclusion of the Montreal Protocol on Substances that Deplete the Ozone Layer (hereinafter referred to as the "Montreal Protocol") and the 19th Meeting of the Parties to the Protocol.
According to the agreement, the developed countries will begin to reduce the production and use of HCFCs from 2010 and will completely stop production and use in 2020; developing countries will begin to cut HCFC production and use from 2015. In 2030, production and use will be completely stopped. According to the original plan, the time for production and use of HCFCs in developed and developing countries will be 2030 and 2040, respectively.
Steiner praised this as a crucial move by the international community to solve the problem of climate change. The early ban of HCFCs is expected to reduce the emission of billions of tons of greenhouse gases. He also said that this is the most significant historical breakthrough made by the international community in the negotiations on environmental issues in the past five to six years. It can provide impetus for the UN climate conference to be held in Bali, Indonesia this December.
Steiner also particularly praised China for its very positive cooperation attitude in the negotiation of the agreement, although implementation of the plan has a great impact on China.
On September 16, 1987, 24 countries signed the "Montreal Protocol", and China became a party to the Protocol in 1991. Over the past 20 years, through the joint efforts of all parties to the Protocol, the world has successfully reduced 95% of the ozone-depleting substances, and the protocol is also recognized as one of the most successful international environmental conventions to date.
EVA compound glue is a kind of glue, the main components are thermoplastic styrene-butadiene rubber, rosin modified resin, petroleum resin, solvent. Mainly used for bonding of EVA materials, wood, leather, EPE and other materials.
EVA is used for EVA and EVA, ABS, PS, AS, rubber, leather and other substrates, and has a particularly good bonding effect, especially ABS, EVA and other materials can be directly bonded without treatment.
EVA product features
1. Wide range of use, used for mutual adhesion of EVA and EVA, ABS, PVC, PS, AS, rubber (except silicone), leather, wood plastic and other materials.
Second, the bonding effect is good, and the aging time is long, which fundamentally changes the characteristics of 502, which is only suitable for short-term positioning, and meets the needs of long-term firm bonding of products.
3. One-component, no need to treat water, one-time gluing, more convenient to use and higher production efficiency.
4. The cured product after bonding has super flexibility, can withstand severe beating and falling, is not easy to peel off, and has good cushioning properties.
Five, ultra-low odor, in line with RoHS standards, environmental protection and health. The shelf life is very long, which can reach more than two years.
6. High strength and high transparency.
7. The initial adhesion is super strong and the toughness is good, which is suitable for bonding products with strong rebounding force.
