The first step in the degradation is most probably the classical ester scission reaction to give a carboxylic acid and olefinic end groups. Further ester scission on the adjacent ester groups of carboxylic acid and olefinic molecular chains can then lead to the formation of lower weight pyrolytic products, such as: CH〓=CHOCOPhCOOCH=CH〓、CH〓=CHOCOPhCOOH and HOOCPhCOOH, and they can pyrolyze continually to produce substrate pyrolytic compounds, such as: HOOCPhCOCH〓、PhCOOH、PhH、PhCOCH〓 and CO、CO〓. At the same time, a corsslinking cyclization reaction occurred of the formation of the gas products during the degradation of PET.

断裂大分子链端邻近羰基和乙烯基的酯键持续断裂，不断地形成小分子裂解产物，如：CH〓=CHOCOPhCOOCH=CH〓、CH〓=CHOCOPhCOOH以及HOOCPhCOOH，这些产物还会进一步裂解成分子量更低的小分子裂解产物，如：HOOCPhCOCH〓、PhCOOH、PhH、PhCOCH〓以及CO、CO〓等，与此同时，一部分乙烯基酯端基的大分子链碎片会发生支化而相互连接，再经&链脱离&和环化反应形成难燃的交联产物。

The characteristic of this installation compared with toe technologys now availatble is as follows; it needs no driving power, the structure of which is very simple; the water-supply height is not restricted for any factors within the most scops. Using H-O internal storing high-pressure gas pope as the pessure device, we can at least make the water-supply height to be 403.2 metres. If we use 16MPa mine filter press, transfering water freeboard can be very, and the height of weater-supply will be at least 1,644 meters, If the strenth of alloyed steel is desighed to be at least 50kg per square millimeters, the water-supply height will reach 50,565.6 metres.

该装置与现有技术相比其特点是：结构简单，不用动力，且上水高度在较大范围内不受任何条件的限制，采用H－0型内贮式高压气管作加压工具，从而使上水高度最少为403.2米，如果使用16MPa矿压机便可实现超高输水，其上水高度最少为1644米，按照合金钢强度最低50千克力／平方毫米设计，该装置的上水高度最少可达到50565.6米。

Noise can be reduced by about 2 dB by using oil-resistant rubber isolator to reduce solid-borne sound transmission;the setting-up of semienclosed noise barriers can not only reduce the work region's noise of workshop by 13 dB,but also adapt to the gas's characteristic involved with H2S,CO,and other poisonous components without supplied m...
