The new technology for preparing fully degradable plastic materials using CO2 as a raw material jointly developed by Jiangsu Zhongke Jinlong Co., Ltd. and the Guangzhou Institute of Chemistry, Chinese Academy of Sciences recently passed the major scientific and technological achievements appraisal organized by the State Environmental Protection Administration. This technology has developed a new CO2 copolymerization catalyst separation system and obtained an aliphatic polycarbonate polyol with a colorless catalyst content of less than 1 mg/L, which can produce polyurethane materials. This new type of biodegradable foam can be applied to packaging materials and has a broad market prospect.
Experts believe that the products produced by this new technology are not only low in cost but also completely degradable, solving the “white pollution†hazard and opening up new avenues for the recycling of greenhouse gases CO2. This technology can not only provide a new raw material for polyurethane, but also can be derived from many new products, thus forming a new plastic industrial chain.

Functions of eye black
1. It has the effect of lengthening eyelashes and enlarging eyes.
2. It can bring curling and supporting force to eyelashes.
3. It can improve the support of eyelashes, and the shape of eyelashes is curved. Especially when we blink and close our eyes, these two layers of eyelashes like small fans can prevent the upper eyeliner from contacting the oil of the lower eyelid and faint, so it is necessary to curl the eyelashes before brushing them.
Misuse of eye black
1. Apply eye black more than 3 times. It is enough to apply eye black twice. If you don't want your eyelashes to form a ball, generally speaking, you can get the best effect by applying it twice.
2. Insert and pull the eyelash brush. It is easy to harden mascara, because air is mixed in the process. Eyelashes are easy to coalesce, and the floating powder is serious.
3. Start applying eye black from the middle of your lashes. When you apply eye black, you must start from the root. eye black is not used for a long time, and it will dissolve when you apply it, so the application method is likely to be wrong. The possibility is as high as 99%. Generally, the curly eye black with larger mascara brush is used.
4. At first, eye black was too thick. Sweep up gently, and then emphasize the wavy feeling when smearing according to personal conditions. Too much mascara at a time is easy to get dirty, because the eyelash state has not been adjusted to the best.
