塑料填料是在软填料和半软填料的基础上发展起来的。它有两个优点。其结构是将塑料盘压扣成双环大塑料环,环上压有醛纤维或聚酯纤维,使纤维束分布均匀;内环为雪花状塑料树枝,不仅可以挂膜,还可以有用地切割气泡,提高氧气的转移率和利用率。水气生物膜充分交换,水中有机物得到高能处理。

Plastic filler is developed on the basis of soft filler and semi soft filler. It has two advantages. The structure of the utility model is that the plastic disc is pressed and buckled into a double ring large plastic ring, and the ring is pressed with aldehyde fiber or polyester fiber to make the fiber bundle evenly distributed; The inner ring is a snowflake shaped plastic branch, which can not only hang film, but also cut bubbles to improve the transfer rate and utilization rate of oxygen. The water vapor biofilm is fully exchanged, and the organic matter in water is treated with high energy.

再生塑料颗粒中填充料起控制成本和改进特性的功效。填充料通常分有机化学填充料和无机物填充料,那麼怎么才能辨别出再生塑料中填充料是有机化学的還是无机物的呢?主要由无机填料组成的填料是与大部分材料性质完全不同且不相容的固体物质,因此它们可以通过相对简单的方法进行分离和鉴定。
The fillers in recycled plastic particles can control cost and improve properties. Fillers are usually divided into organic chemical fillers and inorganic fillers. How can we tell whether the fillers in recycled plastics are organic chemical or inorganic? The fillers mainly composed of inorganic fillers are solid substances which are completely different and incompatible with most materials, so they can be separated and identified by relatively simple methods.
鉴定塑料填料的常用方法是灰化和溶解。灰化鉴别方法是先将含有填料的塑料颗粒灰化,然后放入高温炉中熔化并燃烧聚合物,烧掉有机物,剩下的无机填料用元素特征分析法鉴别。塑胶灰化溫度通常为600℃上下,热固性塑料可低某些,热固性塑料要高某些、那样能够使塑胶充足溶解。融解鉴别法适用未化学交联塑胶,挑选适度有机溶剂将塑胶本身融解,填充料做为不溶物被提取。
Ashing and dissolving are commonly used to identify plastic fillers. The method of ashing identification is to incinerate the plastic particles containing fillers, then put them into a high temperature furnace to melt and burn the polymer, burn the organic matter, and identify the remaining inorganic fillers by element characteristic analysis. The ashing temperature of plastics is usually about 600 ℃. Thermosetting plastics can be lower than thermosetting plastics. Thermosetting plastics should be higher than thermosetting plastics, so that the plastics can be fully dissolved. The melting identification method is suitable for non chemically crosslinked plastics. Appropriate organic solvents are selected to melt the plastics, and the fillers are extracted as insoluble substances.
对于交联材料,化学分解方法如水解、碱性水解、酸解、氨解等。可用于在溶剂中分解和溶解大部分材料以分离填料。分离出的填料可以通过元素分析或仪器分析来鉴定。
For crosslinked materials, chemical decomposition methods such as hydrolysis, alkaline hydrolysis, acid hydrolysis, ammonolysis, etc. It can be used to decompose and dissolve most materials in solvent to separate fillers. The separated fillers can be identified by elemental analysis or instrumental analysis.
