1. first, there are a lot of chemical products that can not find the more suitable alternatives under the conditions promised. For example, we all know the decorative adhesive coated guess urea formaldehyde resin (UF) free formaldehyde problem inside, although so many years we have very much domestic and foreign enterprises or Research Institute, laboratory, Ye Hao, Ye Hao, are trying to find the UF resin substitute, there are some products of the product. For example, the MDI class. But the problem is that these new alternatives, on the one hand more than UF resin high many times, and the practice of the function is a lot worse, and better practice green, capital is expensive do not know how much (not doubled two times, is likely to be the number of times a hundred times) - so now in addition to some high-end products, is still the most important selection of UF resin adhesive coated guess.
2. the second is that even if the money is promised, it can not ensure the complete use of dangerous chemicals. This doesn't talk much. It's very good to know that explosives are dangerous chemicals. Why is it risk that it can explode? There is no substitute, even a safety explosive can be fried, and there is no explosive that cannot be blown up. For other things, most of the green chemical tests made in the laboratory are difficult to expand to the scale of industrial production. This part is still the effort of demand chemistry and chemical workers, but they are now paying low wages and trying to move.
3.the whole system of chemical industry has now been formed for such a long time, not today to say green, tomorrow can be green success. Not a company is green, and it's completely green. The division of labor in the chemical industry is very clear now, and few of the factories have the ability to do the products from the primary chemical raw materials. Is a factory produces the most primary chemical raw materials, and then sold to downstream do intermediate chemical plant, chemical plant to do intermediate raw materials into intermediate, and then sold to downstream manufacturers and intermediates, layers of processing, eventually sold to make products factory (such as cosmetics factory, food factory, for example) into the hands of consumers products and OEM nachulaimai. Now the chemical variety is very jumbled and diverse, almost every kinds of chemicals have their common characteristics in production, production of each chemical will be green tough -- perhaps a small cannot you see on the road next to the small building, took control of the country in more than half of some chemicals market for a IT are more simple to understand vocabulary: chemical production is highly fragmented, this fragmentation has greatly increased the response from its green chemical industry will be difficult.
4.Gongsifenming, now under the condition of hazardous chemicals, decreased the damage doesn't demand from the response itself, we only need to ensure that our chemical produced adverse effect not the outside world can be, we need to ensure that: 1) the most basic: after all products are not to use the health damage; 2) damage without the formation of hazardous chemicals production and storage process. These two points can be reached in theory now, but the demand for these two points depends on supervision and real supervision. But now the regulation is very strange, too - small businesses here, big business too Niubi and can not control, can only pick some medium-sized enterprises -- the tube supervision plays the effect is limited, so can only hope that their importance to the safety production of their alert (because once out of trouble, enterprises themselves the first place is certainly the victim). Some large scale businesses have relatively complete safety response systems. However, more and more small businesses do not understand this. Maybe they lost their understanding because of their pursuit of profit.
