when the time is too long at high temperature, the material will be reduced&put co2 into yellow. do not use ldpe, pom, abs/pa tube cleaning machine. use ps to clean up.、the thermal sealing of lldpe film is good, so long as the lowest sealing temperature is reached, it has good heat sealing strength,&the sealing ability of the seal is strong.、(5) when the shrinkage/vacuum bubble occurs, other conditions can not be solved, adding back pressure can be solved between 5kg/cm2~20kg/cm2. if the back pressure is too high, it will cause overheating&difficult driving.、tpv主要由二部分组成,一是塑料,作为连续相,二是橡胶作为分散相。通常橡胶需要与软化油或增塑剂与之配合。化剂和一些助剂也是必不可少的。另外为了成本或者某方面的性能,一些无机填料会被填加。许多塑料和橡胶之间可形成tpv,但仅有个别共混物经过动态化后具有实用价值,目前商业化的有pp/pe/epdm,pp/nbr,pp/acm,ps/sebs。在化工出版社《热塑性弹性体》一书中对11种橡胶和9种塑料制备的99种橡胶/塑料共混物进行了,研究发现,要性能的橡胶/热塑性塑料动态化共混物,必须以下条件:1塑料和橡胶两种聚合物的表面能匹配;2橡胶缠结分子链长度较低;3塑料的结晶度大于15%。当塑料与橡胶之间的极性或表面能差别比较大的情况下,添加的相容剂,再进行动态化,也可以良的共混物。、saturation 0.40%、the worlds largest manufacturer of abs five are: china cmo company, the total capacity of 1 million 250 thousand tons / year, of which 1 million tons / year, zhenjiang tainan plant unit of 250 thousand tons / year; the total production capacity of 930 thousand tons / year of bayer lg; chemical total production capacity of 700 thousand tons / year; ge plastics ge total capacity of 650 thousand tons / year; basf production capacity of 560 thousand tons / year, five enterprises accounted for 55.6% of the worlds total production capacity. five major production enterprises he accounted for more than half of the global abs capacity. due to the large gap of abs supply in the mainland of china, a large number of products he been exported to china. at the same time, chi mei&lg he set up factories in mainland china&he the intention of expanding [3].、from the point of view of the product, the packaging film accounts for more than 50% of the total amount of the packaging plastic. the biaxially oriented polypropylene (bopp) film is one of the largest consumption areas of pp resin in china. in 2003, 86 bopp production enterprises (123 production lines) were produced in china. the total production capacity is 1 million 400 thousand t/a,&2 million t/a (138 production lines) in 2004. the output will exceed 1 million t. domestic enterprises focus on improving product competitiveness,&he introduced a number of advanced bopp production equipment. the width of the film is 8.3m,&the line speed is as high as 400~500m/min. according to chinas existing bopp film production capacity conversion, the annual demand for pp resin of nearly 2 million t, with high speed, so it should be extended pp spel material, good transparency in the development of bopp films, including attention, ethylene propylene copolymer used in supporting, in order to adapt to the introduction of new equipment of bopp films.、 、advantage、thousands of thai plastic professional sales. makrolon 2405 pc bayer materialscience ag (gen kos)、 、eva 1, widely used in foam material, functional films, packaging mold, hot melt adhesive, wire&cable&toys&other fields.、the performance of pet、the pom enhanced pom
