摘要： Foam particles of propylene polymers which have shrunk from 40 to 95% of their original volume and have a bulk density of from 10 to 30 g/1 can be expanded if they are treated with air or nitrogen under superatmospheric pressure, subsequently decompressed. If desired post-foamed by heating and, after aging, re-treated with air or nitrogen under superatmospheric pressure, subsequently decompressed and aged under atmospheric pressure until the pressure in the cells has dissipated.
摘要翻译： 如果在超大气压下用空气或氮气处理，则其膨胀的丙烯聚合物的泡沫颗粒已经收缩了其原始体积的40至95％并且具有10至30g / l的堆积密度，随后减压。 如果需要通过加热发泡，并且在老化之后，在空气或氮气中在超大气压下再次处理，随后在大气压下减压和老化，直到电池中的压力消散。

摘要： A fireproofing material based on alkali metal silicates and containing from 20 to 60 percent by weight of water, which additionally contains from 1 to 10 percent by weight of a borate or an aluminate, preferably sodium aluminate, to improve the aging resistance. The fireproofing material can be used to insulate apertures and passages in building structures against the passage of fire and smoke, and can also be used as a fireproof glass.
